The conventional automobile braking system is mostly used for the existing new energy automobile, and the kinetic energy of the automobile is dissipated into the air in the form of heat energy through a wheel-side brake and a brake disc or a brake drum; or a part of braking energy is recovered to the power battery in a negative torque rectangular mode generated by the motor.

However, in the traditional mode of dissipating the kinetic energy of the vehicle into the air in the form of heat energy, the brake can be rapidly heated, the heat fading phenomenon occurs, the braking distance is increased, even the braking failure can be caused, the service life of the brake shoe is greatly shortened, a large amount of dust pollution is generated, and the braking capability is influenced; in addition, although some new energy automobiles are additionally provided with a braking energy recovery system, namely a system for recovering a part of braking energy into a power battery in a negative torque rectangular mode generated by a motor, the conversion power of the system is limited, and the braking power is insufficient due to the braking mode of generating negative torque by the motor, so that the requirement of completing braking in a short time cannot be met, and emergency and quick braking cannot be realized.

The automobile kinetic energy recovery device disclosed in patent application No. CN201510073928.7 comprises a fixed shell fixed with an automobile frame, wherein a first clamping piece and a second clamping piece are arranged on the end wall of the fixed shell; the rotating disc is synchronously connected with the automobile axle and is positioned on one side of the fixed shell, and a third clamping piece opposite to the first clamping piece and a fourth clamping piece opposite to the second clamping piece are arranged on the rotating disc; the outer sleeve is arranged on the inner side of the side wall and can rotate around the central axis of the fixed shell relative to the fixed shell, and the outer sleeve is positioned between the first clamping piece and the third clamping piece; the inner sleeve is arranged on the inner side of the outer sleeve and can rotate around the central axis of the fixed shell relative to the fixed shell, and the inner sleeve is positioned between the second clamping piece and the fourth clamping piece; the two free ends are respectively connected with the torsion elastic pieces on the inner sleeve and the outer sleeve; the first driving unit and the second driving unit respectively drive the inner sleeve and the outer sleeve to axially move. The torsional elastic element and the clutch mechanism are used for accumulating the kinetic energy lost during braking, and the accumulated braking kinetic energy is converted into the elastic potential energy of the torsional elastic element, so that the elastic potential energy of the torsional elastic element is used for driving the axle to rotate when the automobile starts and accelerates. The automobile kinetic energy recovery device has the advantages that the number of parts is less than that of the parts in the prior art, most of the parts are common transmission parts, so that the transmission efficiency is relatively high, the safety coefficient is higher, and the manufacturing cost is lower.

However, in the practical use process of the kinetic energy recovery device, we find that the two end states of the torsional elastic element are switched by the telescopic movement of the linear motor, and the meshing of the convex teeth and the tooth grooves is utilized to realize the rotary butt joint during the telescopic movement, although the butt joint and the switching can be realized, the abrasion to the convex teeth and the tooth grooves in the whole process is extremely serious, and because the real-time positions and states of the corresponding convex teeth and the tooth sockets are not fixed, rigid contact and collision are easily caused when the convex teeth are butted with the tooth sockets, namely, the convex teeth are not inserted into the concave parts of the tooth grooves, so that the loss of the component is further increased, the linear motor continues to work and stretch, however, the protruding teeth and the tooth grooves are abutted at the moment, so that the linear motor cannot extend, and the service life of the linear motor is seriously influenced, and therefore, the disc type brake device for converting the kinetic energy of the new energy automobile is provided.

when the pedal is released, the time relay 43 is triggered, the first strong electromagnet 41 is instantly electrified with forward current, the inserted rod 36 is instantly sucked and inserted in the positioning frame 34, meanwhile, the second strong electromagnet 42 is electrified with reverse current, so that the inserted rod 36 of the inner ring of the coil spring 31 is inserted in the groove 33, at the moment, the elastic potential energy generated when the inner ring of the coil spring 31 is reset is utilized to assist the wheel disc 1 to start, the time relay 43 presets time, and when the preset time of the time relay 43 is reached, the time relay 43 instantly controls the second strong electromagnet 42 to be electrified with forward current, suck the groove 33 and reset and inserted in the positioning frame 34 for continuous use.

It should be noted that, in the process of inserting the inserting rods 36 into the grooves 33 respectively, as the wheel disc 1 rotates, the inserting rods 36 may not be inserted into the grooves 33 correspondingly while being ejected, and it may be a practical situation that the inserting rods 36 are inserted into the outer sides of the positions of the grooves 33 of the wheel disc 1 correspondingly, which may affect the stable energy storage of the coil springs 31 at this time, but it should be noted that, at this time, although the automobile is in the braking state, the automobile body is not stopped at the beginning of braking, but only at the beginning of braking, and as the tire and the wheel disc 1 rotate, when the grooves 33 rotate to the positions of the inserting rods, the inserting rods 36 are directly pushed and displaced until being inserted into the grooves 33, so as to be used for kinetic energy conversion.

Referring to fig. 10, it is further optimized that the inserting rod 36 may not be directly inserted into the groove 33 at a time, in the present application, the inserting rod 36 includes a first combining rod 361 and a second combining rod 362, the strong electromagnet 41 and the strong electromagnet 42 are respectively installed on the corresponding first combining rod 361, and one side of the first combination rod 361 close to the wheel disc 1 is provided with a displacement groove 364, the second combination rod 362 is slidably arranged at the notch position of the displacement groove 364, and a compression spring 363 having two ends respectively connected to the second combined rod 362 and the inner wall of the displacement slot 364 is provided in the displacement slot 364, so that the insert rod 36 has the ability of expansion and contraction, so that when it is not inserted into the groove 33, the second combined rod 362 can be contracted in the first combined rod 361 to reduce the friction loss when the inserted rod 36 is pushed by strong magnetism to be in close contact with the wheel disc 1, thereby effectively prolonging the service life of the wheel disc.

Furthermore, the magnetism of the first strong electromagnet 41 and the second strong electromagnet 42 is made of soft iron materials, so that the first strong electromagnet and the second strong electromagnet are attracted by the strong magnet 51 in a current-free state, the stability of the position of the inserting rod 36 is ensured in a parking state through the design, the inconvenience of pushing the inserting rod 36 into the groove 33 accidentally when the vehicle is pushed to move under the condition of vehicle fault exercise is avoided, and the coil spring 31 is extremely easy to be excessively wound in the process so as to be damaged.

Further, the mounting sleeve ring 2, the coil spring 31 and the positioning plate 37 are all of a combined structure, namely, the two identical half structures are spliced outside the automobile driving shaft by using hidden screws, so that the mounting sleeve ring is convenient to disassemble, assemble and replace.

In addition, in the application, the maximum winding number of the coil spring 31 is assumed to be X1, the effective braking distance of the automobile is X2, and the circumference of the wheel roller is X3;

x1 > X2/X3;

wherein X2/X3 is the revolution of automobile tire in the course of standard braking distance, and every revolution of tire and rim plate 1, the corresponding revolution of coil spring 31, further, can set up X1 > 2 (X2/X3), in order to consider the situation that the braking distance increases after the tire wears, and then the maximum condition of avoiding rim plate 1 to drive the condition of the transitional coiling of coil spring 31, guarantee its life.
