Detailed Description

Fig. 1 is a schematic structural view of a section of an output shaft and gears of a synchronization device 100 according to an embodiment of the present invention. Specifically, the synchronization device 100 of the present embodiment may include the gear 10 and the output shaft 20. Wherein, the inner ring of the gear 10 is provided with a friction plate groove 11. The output shaft 20 is provided with an oil inlet hole 21 having one end closed, and an oil outlet hole 22 communicating with the oil inlet hole 21. The outer side of the output shaft 20 is connected with a friction plate 23, and the oil outlet 22 can guide the hydraulic oil at the oil inlet 21 to the friction plate 23. The output shaft 20 is arranged on the inner ring of the gear 10, the friction plate 23 is clamped in the friction plate groove 11, and hydraulic oil entering the output shaft 20 from the oil inlet 21 enters the friction plate groove 11 from the oil outlet 22 to push the friction plate 23 so that friction force is formed between the friction plate 23 and the side wall of the friction plate groove 11, so that the gear 10 and the output shaft 20 are synchronous.

The synchronizing device 100 of the present embodiment includes only the output shaft 20 and the driven gear 10 provided on the output shaft 20, and is compact and simple in structure, saving space for arrangement. In addition, the synchronizer 100 of the present embodiment eliminates mechanical devices (a hub, a sleeve, an engaging tooth, and a synchronizing ring), reduces the occurrence of secondary impact, and avoids the generation of mechanical noise at the end face of the engaging tooth of the gear sleeve.

FIG. 2 is a schematic block diagram of an output shaft of a synchronizing device according to one embodiment of the invention; FIG. 3 is a schematic side view of an output shaft of a synchronizing device according to one embodiment of the invention; FIG. 4 is a schematic block diagram of a gear of the synchronization device according to one embodiment of the present invention; as a specific example, one end of the output shaft 20 of the synchronization device 100 of the present embodiment is provided with a plurality of magnetic members 24. A battery 12 and an induction coil 13 are provided at the gear 10. The battery 12 is connected with the induction coil 13, the battery 12 is used for providing current for the induction coil 13 to generate a magnetic field, and the current generated by the induction coil 13 can charge the battery 12. The induction coil 13 is close to the plurality of magnetic members 24, so that when the battery 12 supplies current to the induction coil 13 to generate a magnetic field, the induction coil 13 and the magnetic members 24 form a force of mutual attraction or mutual repulsion, and the gear 10 can be regulated. The magnetic member 24, the induction coil 13 and the battery 12 are provided in the synchronizing device 100 of the present embodiment to assist in synchronizing the gear 10 with the output shaft 20 using hydraulic oil. Specifically, when the vehicle gear shift requirement is low, the hydraulic oil input at the output shaft 20 can be directly utilized to enable the friction force to be formed between the friction plate 23 and the friction plate groove 11, and further enable the output shaft 20 and the gear 10 to be synchronized. When the vehicle has high gear shifting requirements and a large rotation speed difference, the rotation speed difference can be reduced by utilizing the electromagnetic force generated among the battery 12, the induction coil 13 and the magnetic part 24, so that the synchronous friction plate 23 is assisted to perform a synchronous function, and the synchronous performance is improved.

As a specific example, in the present embodiment, when there is a difference in rotational speed between the gear 10 and the output shaft 20, there is a difference in rotational speed between the magnetic member 24 and the induction coil so that the induction coil cuts the magnetic induction wire to generate a current to charge the battery 12. Specifically, when the vehicle is in a neutral operating condition, the rotation speed difference between the gear 10 and the output shaft 20 causes the rotation speed difference between the induction coil 13 and the magnetic member 24, so that the induction coil 13 cuts the magnetic induction lines of the magnetic member 24, and current is generated to charge the battery 12. The synchronous device can not only utilize the electromagnetic force to assist the synchronous process of the synchronous device 100, but also charge the battery 12 through the principle of magnetic electricity generation, thereby realizing energy recovery.

As a specific example, as shown in fig. 2 and 3, the output shaft 20 of the present embodiment has a cylindrical shape, the oil inlet hole 21 is located on the central axis of the output shaft 20, and one end of the oil inlet hole 21 is open and the other end is closed. The plurality of magnetic members 24 are uniformly disposed at the outer sidewall of the closed end of the output shaft 20. Specifically, the magnetic member 24 may be a permanent magnet, and may be an electromagnet. The number of the magnetic members 24 may be at least two, and the number of the magnetic members 24 is 4 in the present embodiment. The number of magnetic elements 24 can be freely designed according to the force requirements at the actual vehicle gear change.

Specifically, as shown in fig. 2 and 3, the oil outlet hole 22 is located at the side wall of the output shaft 20 and extends in the radial direction, the oil outlet hole 22 includes an oil inlet 223 communicating with the oil inlet hole 21 and oil outlets 221, 222 located between the friction plates 23. Since the synchronous force between the gear 10 and the output shaft 20 is derived from the friction force between the friction plate 23 and the friction plate groove 11, and the friction plate 23 is clamped in the friction plate groove 11, the hydraulic oil can be well input to the position between the friction plate 23 and the friction plate groove 11 through the oil outlets 221 and 222 on the side edge of the friction plate 23, so that the synchronous process of the synchronous device 100 is ensured.

As a specific embodiment, the friction plate 23 of the present embodiment is plural, and an oil outlet of at least one oil outlet hole 22 is provided at both sides of each friction plate 23. A valve (not shown in the drawings) is provided at the oil inlet 223 of the oil inlet hole 21 so that the oil outlet hole 22 is controllably opened and closed, and the oil outlet holes 22 on the same side of the plurality of friction plates 23 are simultaneously opened or closed. Specifically, as shown in fig. 2 and 3, the number of the friction plates 23 of the present embodiment may be 3, and the number of the friction plate grooves 11 may also be 3. A first oil outlet 221 is arranged at the left side of each friction plate 23, and a second oil outlet 222 is arranged at the right side of each friction plate 23. All first oil outlets 221 are opened or closed simultaneously, and likewise all second oil outlets 222 are opened or closed simultaneously. Since the gear 10 and the output shaft 20 are synchronized by pushing the friction plate 23 with hydraulic oil in this embodiment, so that there is friction between the friction plate 23 and the friction plate groove 11, if the forces pushing to the two sides of the friction plate 23 are the same, they are easily balanced with each other, so that the force between the friction plate 23 and the friction plate groove 11 is almost 0, and the synchronization requirement is not met. Therefore, during the synchronization function of the synchronization device 100, the oil inlets 21 on the same side of the friction plates 23 are opened uniformly, so that the hydraulic oil applies a force in the same direction to the friction plates 23 from the same side of the friction plates 23, thereby implementing the synchronization process. For example, in the present embodiment, the oil outlet hole 22 on the left side of the friction plate 23 is opened first, so that the hydraulic oil enters into the friction plate groove 11 from the first oil outlet 221. After the synchronization process is completed and when the pressure needs to be relieved, the oil inlet 21 on the other side needs to be opened, that is, at this time, the hydraulic oil enters the friction plate groove 11 from the first oil outlet 221 and the second oil outlet 222, so that the forces given to the friction plate 23 by the hydraulic oil on the two sides of the friction plate 23 are balanced with each other, and the pressure relief is realized. The two oil inlet modes realize the switching between synchronization and neutral position.

Specifically, the working principle of the synchronizing device 100 of the present embodiment is that the hydraulic oil in the output shaft 20 is controlled to form pressure in the friction plate groove 11 in a hydraulic manner to push the friction plate 23 of the hydraulic device to realize a synchronous output function, and when the synchronizing function is exited, the left side and the right side in the oil hole of the output shaft 20 realize a pressure-withdrawing function and a pressure-increasing function to realize the switching between the synchronization and the neutral gear.

The magnetic member 24, the induction coil 13 and the battery 12 in this embodiment are auxiliary to the synchronization process of the different devices. The specific process comprises the following steps: the battery 12 is controlled to output corresponding current to the induction coil 13, and magnetic force is generated between the induction coil 13 and the magnetic member 24 by the principle of electromagnetism generation, namely, the principle of like poles repelling each other and opposite poles attracting each other, so that the driven gear 10 is regulated. In the neutral position, a rotation speed difference is formed between the magnetic part 24 and the induction coil 13 so as to cut magnetic induction lines, and current is generated to charge the battery 12 for energy storage. When the D gear is shifted up, discharging is carried out through the target rotating speed difference to the induction coil 13 to realize the speed regulation function, and the synchronous process is increased to reduce the synchronous pressure of the clutch friction plate 23. When the gear D is shifted down, the same principle is adopted, the drag torque is counterbalanced, and the hydraulic friction system is assisted to realize the synchronization function. Because the structure is different from the traditional synchronizer structure, and no gear sleeve, synchronous ring and joint gear exist, the secondary impact Clink noise and the impact limiting end face noise do not exist, the comfort of the whole vehicle is greatly improved, and the policies of energy recovery, energy conservation and emission reduction are realized.

FIG. 5 is a schematic block diagram of a synchronizer governor system according to an embodiment of the present invention. As a specific embodiment, the synchronization device governing system 200 of the present embodiment may include the above synchronization device 100, the information obtaining module 30, the calculating module 40, and the control module 50. The information acquiring module 30 is used for acquiring information of the vehicle. The calculation module 40 calculates a force value required for synchronization according to the information of the vehicle, and calculates an oil inlet speed of hydraulic oil required in the synchronization device 100 and/or a current value required to be supplied to the induction coil 13 by the battery 12 according to the force value. The control module 50 controls and adjusts the oil inlet speed of the hydraulic oil of the synchronization device 100 and/or the discharge current of the battery 12 according to the oil inlet speed value and/or the current value of the hydraulic oil, so as to realize the speed regulation of the synchronization device 100.

As a specific example, the information of the vehicle includes the rotation speed of the output shaft, the rotation speed of the current input shaft, the pre-shift speed ratio, the synchronization time, the actual angular acceleration. The calculation module obtains a rotation speed difference according to the rotation speed of the output shaft, the pre-gear ratio and the rotation speed of the current input shaft; and then obtaining a target angular acceleration according to the rotation speed difference, and comparing and feeding back the target angular acceleration and the actual angular acceleration obtained by real-time detection to obtain a force value required for synchronization.

More specifically, the calculation process of the calculation module of this embodiment specifically includes:

multiplying the collected rotating speed of the output shaft by the pre-gear ratio to obtain the rotating speed required by the pre-gear;

subtracting the rotating speed of the input shaft at the current gear from the rotating speed required by the pre-engaged gear to obtain a rotating speed difference;

dividing the synchronous time by the rotating speed difference to obtain a target gradient, namely a target angular acceleration;

and inputting the synchronous gradient rate to a formula multiplied by a Ks coefficient through radial feedback of the target angular acceleration and the actually measured actual gradient, namely the actually measured angular acceleration to obtain the synchronous target force. Specifically, the formula Fs ═ Ms × Ks + Fd, where Fs is the target synchronization force, Ms is the friction torque, Ks is the adjustment coefficient, and F is the adjustment coefficient_DTo lock the detennt force. Wherein Ms is J × N + (± Md), J is moment of inertia, N is gradient, i.e., angular acceleration, and Md is drag torque. Adjusting coefficient Ks as initial default coefficient, adjusting properly when detecting the difference between the target and the actual valueNode +0.1 or-0.1.

And obtaining a corresponding voltage value according to the synchronous target force, and obtaining a corresponding current value according to the voltage value, so as to obtain an output current value of the battery 12 required to be controlled. The rotation speed of the speed regulating device is controlled in such a way as the force is in direct proportion to the output current.

In other embodiments, the oil inlet speed value of the corresponding hydraulic oil is obtained according to the synchronous target force, and the oil inlet speed of the output shaft 20 is controlled according to the oil inlet speed value, so as to achieve the purpose of speed regulation.

Specifically, after the pre-engaged gear target force is obtained, calibration is carried out through a hydraulic oil pump power/motor and a calibration team to establish, finally selection and calling are carried out in a table lookup interpolation mode, and finally realization is carried out in a pressure/electronic control mode.

The speed regulating system 200 of the synchronization device of the embodiment can directly control the oil inlet speed of the synchronization device 100 and/or control the discharging current value of the battery 12 according to the target rotating speed of the vehicle and the current information of the vehicle, so as to realize the gear shifting synchronization speed regulating function of the synchronization device 100, and the synchronization gear shifting and speed regulating process is simple and rapid, and has good synchronization performance, low energy consumption and low production cost.

As a specific embodiment, the present embodiment also provides a vehicle including the above synchronizer speed control system 200. The vehicle with the speed regulating system 200 of the synchronizing device has the advantages that the electromagnetic speed regulating function is adopted, the synchronizing performance is better than that of a traditional synchronizer, the structure is more compact, the weight is lighter, the cost is lower, the energy recovery function is provided, the ultra-low energy consumption is realized, the production and manufacturing cost is lower, and the application of the synchronizing function of the gear shifting system is more suitable.
