Abstract

The invention discloses a mechanism capable of realizing forward transmission for two-way driving and reverse transmission for one-way locking. The mechanism comprises a driving shaft, a driven shaftand a fixed shell. Locking grooves are formed in the end face of the driven shaft, engaging teeth are arranged on the end face of the driving shaft, and the engaging teeth are located in the locking grooves. The fixed shell is arranged at the matching position of the driving shaft and the driven shaft in a sleeving mode. Locking mechanisms are arranged in the locking grooves. When the forward-transmission driving shaft rotates reversely and the reverse-transmission driven shaft rotates forwards, the locking mechanisms move away from the inner wall of the fixed shell, so that the driving shaftis in normal transmission fit with the driven shaft. When the reverse-transmission driven shaft rotates reversely, the locking mechanisms are pressed on the inner wall of the fixed shell, so that thedriven shaft is clamped on the fixed shell. According to the mechanism capable of realizing forward transmission for two-way driving and reverse transmission for one-way locking, the function of forward transmission for two-way driving and reverse transmission for one-way locking is realized through the improvement of the matching position of the driving shaft and the driven shaft; and the cost islow, the structure is compact, the occupied space is small, and spatial layout difficulty is low.

Description

technical field

[0001] The invention relates to the technical field of vehicles, in particular to a forward drive bidirectional drive and reverse drive one-way locking mechanism. Background technique

[0002] When a motor vehicle is parked or started on an uphill road, a downward force parallel to the slope is generated due to the vehicle's own weight, that is, the slope resistance, which will cause the vehicle to slide backward along the slope, which is extremely unsafe. For a manual transmission motor vehicle, the driver must coordinate and cooperate with the parking brake, clutch and accelerator pedal when going uphill, but this series of operations is very cumbersome and difficult to master. It is not easy, and this inherent problem has become a major defect of MT vehicles. At the same time, due to the inherent characteristics of AMT vehicles, it is difficult to control the ramp start of AMT vehicles. This major defect of AMT vehicles hinders the popularization and use o...
