Mechanical double overrunning clutch adaptive automatic transmission bridge with planetary system input

Abstract

The invention discloses a mechanical double-overrunning clutch self-adaptive automatic transmission axle with planetary system input, which includes a drive axle housing and a planetary gear train for power input. The transmission system is located in the axle housing, and the transmission system includes a low gear transmission mechanism. , Reverse gear transmission mechanism and adaptive transmission assembly; the reverse gear transmission mechanism has a transmission ratio I that transmits the reverse gear power from the layshaft to the hollow main shaft, and the low gear transmission mechanism has a transmission that transmits the low gear power from the layshaft to the hollow main shaft Ratio II, transmission ratio I is greater than or equal to transmission ratio II; the overall structure of the present invention is simple and compact, and the reverse gear transmission shares the transmission route with the low gear and fast gear transmission, which has strong adaptability, smooth and natural coordination, and improves the overall efficiency. In the axle housing, the overall structure is compact, and the strength and rigidity of the overall axle are improved, and the occupied volume is small. The planetary deceleration input is used to increase the torque, and a high-speed motor can be used as a power source.

Description

technical field [0001] The invention relates to a transmission for a motor vehicle, in particular to a mechanical double-overrunning clutch self-adaptive automatic transmission bridge with planetary system input. Background technique [0002] The working conditions of mechanical transmission systems are generally complex, and torque needs to be distributed to realize the transmission of different loads and speeds. Taking electric vehicles as an example, the driving environment is complex and changeable. Moreover, the electric drive method commonly used in existing electric vehicles is a motor-driven fixed-speed ratio, and the reasonable range of high efficiency is narrow and limited, resulting in a vicious circle, resulting in the following problems: [0003] 1. It can only work within the torque range of a certain working condition. [0004] 2. In order to meet the road conditions under the condition of constant speed ratio, the speed of the motor can only be increased, wh...
