The 'single-side starting transmission system' has the advantages that the power of an engine directly drives wheels or front wheels through the power of one side of a gear shifting and speed dividing device, and the power of the other side of the gear shifting and speed dividing device is transmitted to the wheels through the speed changing of an automatic gearbox.

The 'unilateral starting transmission system' has the advantages that the power of an engine directly drives wheels or front wheels through the power of one side of a gear shifting and speed dividing device, and the power of the other side of the gear shifting and speed dividing device is generated by a generator to be charged by a storage battery and then is supplied to a motor to drive the wheels.

3. The design and application of multifunctional gear-shifting and speed-dividing device with integrated gear-shifting and speed-dividing (differential) functions.

The 'single-side starting transmission system' is suitable for other mechanical transmission and related applications.

The technical field is as follows:

the present invention relates to mechanical transmission drive systems for automobiles and the like.

Secondly, background art:

the development of the automobile industry in the world such as the outbreak growth of well-jet type, the production and sales volume of automobiles are also rising year by year, the rapid development of the automobile industry in China can be said to bring prosperity to the national traffic industry and economy, and people and even countries can feel the importance of the automobile industry, however, most of the main advanced driving transmission technologies of automobiles are still mastered abroad, and the middle-high-end automobile models capable of embodying the advanced technologies of automobiles come from entrances and joint finances, wherein a representative Toyota Puruis hybrid automobile has the key technology monopolized for nearly 20 years until the oil-electric hybrid automobile is gradually popularized, so that the technology related to energy conservation and environmental protection is more important? The single-side starting transmission system is combined with the current energy-saving and environment-friendly concept, the transmission efficiency of the existing automobile is greatly improved, meanwhile, the active transmission parts are reduced and cancelled, the energy conservation and environment protection are realized, the automobile structure is optimized, the manufacturing cost is saved, and the like.

Thirdly, the invention content and implementation:

except for pure electric vehicles, the transmission structure of the vehicle is that an engine drives wheels to move after being changed in speed by a gearbox. The invention relates to a single-side starting transmission system, which is characterized in that engine power directly enters a gear shifting speed divider designed by the inventor, one side of the transmission is transmitted to a wheel or a front driving wheel differential mechanism, the other side of the transmission is transmitted to an automatic transmission, and the transmission is transmitted to the wheel or a rear driving differential mechanism after the speed of the automatic transmission is changed. When the device is applied to a gasoline-electric hybrid vehicle, the other side of the device is transmitted to the generator, the generator generates electricity to charge the storage battery, and then the electricity is supplied to the motor to drive wheels or a rear-drive differential.

The working principle and the specific implementation are as follows:

FIG. 1 is a plan view of a power transmission device for a front-rear drive type automobile, 1 being a starting, 2 being a shift speed-dividing gear, 3 being a transmission, when the engine is accelerated and started, the power is transmitted to the gear-shifting speed-dividing gear by the clutch, the torque transmitted by the gear-shifting speed-dividing gear to the wheel side is small, the vehicle body in a static state is difficult to start, the other side of the gear box is subjected to torque conversion through the automatic gearbox, the torque after torque conversion is large in performance, and the driving wheels can be directly started to run, so that the gear-shifting speed-dividing device plays a key role, because the differential mechanism has a differential function, the power of the engine basically acts on one side of the automatic gearbox, the automobile basically moves in a uniform speed straight line when the power on two sides of the interaction of the gear shifting and speed dividing mechanism and the gearbox is gradually balanced along with the continuous increase of the speed of the automobile after starting, and the gearbox obviously acts under the starting and accelerating functions in the moving process.

Fig. 2 is a top view of a power transmission structure of a front-engine rear-drive hybrid electric vehicle, wherein 1 is an engine, 2 is a gear-shifting differential, 3 is a generator, 4 is an electric motor, 5 is an electric control system, and 6 is a storage battery.

Fig. 3 is a top view of a front four-wheel drive type vehicle power transmission structure, and fig. 4 is a top view of a front four-wheel drive hybrid vehicle power transmission structure, which is structurally modified in that one side of a differential is driven by front wheel drive, and the other side is driven by rear wheel drive through an automatic transmission or a motor, and the operation principle is the same as that of the front four-wheel drive hybrid vehicle power transmission structure.

Design of the gear shifting and speed dividing device:

FIG. 5 is a top view of the power transmission structure of the gear shifting and speed-dividing device, wherein the lower gear is a power input gear, the upper and lower gears of the middle 4 corresponding gears are coaxial rotation gears, the two gears at the two sides are power output gears, and the two outer upper and lower cross beams are integrated into a whole and have left and right sliding grooves to act on a large gear which can be integrated into a whole and slide left and right on a middle small gear shaft. The expression form is as follows:

1. a shift transmission having a differential function.

2. The form in the figure is represented as a neutral state.

3. When the left side gear and the lower side gear of the large gear integrated on the outer side are closed, the gear shifting and speed dividing device is in a forward gear.

4. When the left side of the large gear integrated on the outer side is separated and the right side is closed, the gear shifting speed divider is in a reverse gear.

5. In the practical application process, the transmission speed ratio of the lower side gear and the large gears on the two outer sides is designed according to the performance of the engine, the transmission and the specification of the wheels.

The advantage analysis of the 'single-side starting transmission system':

1. conventional automobiles have a mechanical efficiency of 70% after the engine power is shifted through the transmission, and then the mechanical efficiency of the automobile using the "single-start transmission system" herein should be more than 80%, because nearly half of the power is directly applied to the wheels.

2. Because the power distribution is reduced and the specification of the automatic gearbox is large, the size can be reduced.

3. Under the action of the gear shifting and speed dividing device, the dynamic complementary type buffering at the two sides is more favorable for the stable exertion of the automatic gearbox, and the pause and the frustration existing in the automatic gear shifting of the automatic gearbox are reduced or eliminated.

4. Because the automatic gearbox is separated from the engine, the gearbox is designed at the rear side of the vehicle, the weight of the front vehicle of the passenger vehicle is reduced, the vehicle structure is optimized, and the maintenance is more facilitated.

5. Simplify passenger car hybrid structure, practice thrift manufacturing cost, realize energy-concerving and environment-protective.
