Multi-cam self-adaptive multi-gear automatic transmission countershaft

Abstract

The invention discloses a multi-cam self-adaptive multi-gear automatic transmission countershaft. The countershaft comprises a supporting shaft and a mechanical intelligent self-adaptive variable speed assembly located on the supporting shaft. The mechanical intelligent self-adaptive variable speed assembly comprises an overrun clutch, a torus axial outer taper sleeve, a torus axial inner taper sleeve and a variable speed elastic component. The multi-cam self-adaptive multi-gear automatic transmission countershaft is used in transmissions, has all the advantages of an existing cam self-adaptive automatic transmission, and is of a multi-cam structure, therefore, sensitivity in the gear shifting process is ensured, jerking feeling and jam feeling during gear shifting are eliminated, driving comfort is improved, furthermore, energy is saved and consumption is reduced; the dynamic property, economical efficiency, driving safety and driving comfort of a vehicle are greatly improve. In addition, by means of cams and the cooperative relationships among the cams, a clutch is locked after separation, elimination of the transmission gaps among transmission components is facilitated, transmission precision and efficiency are improved, and drive energy is saved.

Description

technical field [0001] The invention relates to a motor-driven transmission structure, in particular to a secondary shaft of a multi-cam self-adaptive multi-speed automatic transmission. Background technique [0002] In the prior art, automobiles, motorcycles, and electric bicycles basically directly control the throttle or current control speed through a speed control handle or an accelerator pedal, or use a manual mechanical automatic transmission mechanism to realize speed change. The operation of the handle or accelerator pedal depends entirely on the driver's operation, which often causes a mismatch between the operation and the driving conditions, resulting in unstable operation of the motor or engine, and engine stalling. [0003] In motor vehicles, when the driver does not know the driving resistance and only operates the transmission device based on experience, the following problems inevitably exist: 1. When starting, going uphill and with a large load, due to the ...

AI Technical Summary

Problems solved by technology

[0006] In view of this, the object of the present invention is to provide a multi-cam self-adaptive multi-speed automatic transmission sub-shaft, which is suitable for all automobiles and even heavy-duty automobiles. It solves the problem that small torque-rotational speed changes cannot satisfy road use under complex conditions. It has good stability, further improves work efficiency, and has better energy-saving and consumption-reducing effects; it can also realize multi-speed automatic transmission according to driving resistance, further reducing Less frustration and save driving energy consumption; at the same time, the shifting process is smooth without jamming, sensitive response, saving driving energy, reducing energy consumption, and further improving the service life. It is suitable for all motor vehicles and makes the vehicle situation more stable
