Abstract

A speed variator system for motor-driven vehicle is sequentially composed of power unit, master clutch, speed variator, drive unit, and a secondary power unit consisting of secondary clutch, hydraulic pump and hydraulic motor. Its method is also disclosed, which features that the power is continuous in the procedure of speed variation.

Description

technical field [0001] The invention relates to a transmission device of a motor vehicle and a transmission method thereof. Background technique [0002] In a traditional motor vehicle, the transmission system generally includes a power machine, a clutch, a transmission, a transmission member (including the output shaft of the transmission, a universal joint and a drive shaft) and a drive axle (including the final drive, Differentials, axle shafts and transaxle cases). The speed change process of the vehicle is: the driver depresses the clutch pedal to disengage the clutch to cut off the transmission line between the power machine and the driving wheel, and then uses the shift control handle to adjust the gear set in the transmission from one set of meshes to another set of meshes. Afterwards, the clutch pedal is released, the clutch is engaged, and the disconnected transmission line is reconnected, and the power is transmitted from the power machine to the universal transm...
