Problems solved by technology

[0006] In view of this, the purpose of the present invention is to provide a multi-cam self-adaptive multi-speed automatic transmission, which is suitable for all automobiles and even heavy-duty automobiles. It can not only adapt to changes in driving resistance without cutting off the driving force, but also automatically perform gear shifting. , to solve the problem that small torque-rotational speed changes cannot meet the problem of road use under complex conditions, with goo

Abstract

The invention discloses a multi-cam self-adaptive multi-gear automatic transmission. The transmission comprises a box body, a power input shaft, a power output shaft, a self-adaptive variable-speed high gear assembly, a first gear assembly and a self-adaptive variable-speed n-gear assembly, wherein the output revolving speed of the n-gear assembly is lower than that of the high gear assembly and higher than the first gear assembly, and the n-gear assembly comprises a second gear, a third gear......and an nth gear. The multi-cam self-adaptive multi-gear automatic transmission has all the advantages of an existing cam self-adaptive automatic transmission, and is of a multi-cam multi-gear structure, therefore, sensitivity in the gear shifting process is ensured, jerking and jam 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 improved. In addition, by means of the power output shaft, cams and the cooperative relationships among the cams, a cone 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 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 increase in driving r...
