Double-cone friction transmission self-adaptive automatic variable speed spindle assembly

Abstract

The invention discloses a double-cone friction transmission self-adaptation automatic speed changing spindle assembly which comprises a transmission shaft, a slow-gear transmission mechanism and a mechanical intelligent self-adaptation speed changing assembly. Friction faces of drive friction discs and friction faces of driven friction discs of the mechanical intelligent self-adaptation gear changing assembly are in double-cone-face friction transmission. According to the double-cone friction transmission self-adaptation automatic speed changing spindle assembly, the friction discs are adopted to form a separating and combining structure, the beneficial effect of the sensitive response is achieved, and the axial size is small; meanwhile, the structure that the radial sections of the friction faces are trapezoidal annular protrusions are embedded in annular grooves is adopted, double cone faces are formed, the friction faces are disconnected, and therefore coaxiality of the drive friction discs and the driven friction discs is ensured easily, the friction faces are easily enlarged, and good transmission is ensured under the limited elasticity conditions; and sensitivity of separating and combining is easily ensured, transmission precision is improved, and the assembly is suitable for the field of electric vehicles.

Description

technical field [0001] The invention relates to a motor vehicle transmission, in particular to a double-cone friction transmission self-adaptive automatic transmission main shaft assembly. 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 the accelerator pedal depends entirely on the operation of the driver, which often results in a mismatch between the operation and the driving conditions, resulting in unstable operation of the motor and stalling. [0003] In motor vehicles, when the rider does not know the driving resistance, the speed change device is only operated and controlled based on experience, which inevitably has the following problems: 1. When starting, going uphill and with a heavy lo...

Problems solved by technology

[0006] In view of this, the object of the present invention is to provide a side-mounted self-adaptive automatic transmission with wave-shaped friction transmission, which can not only automatically perform gear shifting without cutting off the driving force according to the change of driving resistance, but also solve the problem of torque-rotational speed. Small changes cannot meet the problem of road use under complex conditions; long-term operation can still ensure stable support, reduce operating noise, ensure operating comfort and improve transmission efficiency, thereby reducing energy consumption; change the stroke of the axial joint surface of the fast and slow gear engagement and separation mechanism In the long-term current situation, the separation and engagement are fast and thorough, which is conducive to improving the transmission accuracy. After a long period of use, the overall shape and position tolerance will still be guaranteed, thereby ensuring the stability of the transmission.
