Self-adaptive automatic transmission for dual-overrunning-clutch shaft sleeve output

Abstract

The invention discloses a self-adaptive automatic transmission for dual-overrunning-clutch shaft sleeve output. The self-adaptive automatic transmission comprises a speed control system, and a power output shaft sleeve which is rotatably matched with a main shaft in a sleeving mode, wherein the speed control system comprises a low-speed-gear transmission mechanism, a gear reversing transmission mechanism and a self-adaptive transmission assembly; and the gear reversing transmission mechanism is provided with a transmission ratio I for transmitting gear reversing power to the main shaft from asecondary shaft, and the low-speed-gear transmission mechanism is provided with a transmission ratio II for transmitting low-speed-gear power to the main shaft from the secondary shaft, and the transmission ratio I is greater than the transmission ratio II. Two overrunning clutches are reasonably matched, and the transmission ratios are reasonably set for the gear reversing mechanism and the low-speed-gear mechanism, so that the integral structure is simple and compact, interference is avoided, integral performance of the self-adaptive automatic transmission is guaranteed, and transmission stability is guaranteed; power is output by the shaft sleeve, and an output part can be selected according to the needs, so that the self-adaptive automatic transmission is suitable for the field of electric vehicles, and is also suitable for other variable-torque mechanical transmission fields. Meanwhile, the shaft sleeve output further can guarantee a relatively great output torque.

Description

technical field [0001] The invention relates to a motor vehicle transmission, in particular to a dual overrunning clutch sleeve output self-adaptive automatic transmission. 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, which increases the manufacturing cost of ...
