Transmission automatic shift mechanism

Abstract

An automatic shifting mechanism for a transmission, comprising: a first push-pull electromagnet, a second push-pull electromagnet connected in series, a shifting mechanism with a position sensor for detecting the push-pull electromagnet, an operating mechanism and the A connected controller, wherein: the first push-pull electromagnet is fixedly arranged in the transmission housing, one end of the gear selection mechanism is connected to the second push-pull electromagnet, and the controller collects the detection signal of the position sensor to judge and generate four gear selection positions And whether the gear selection is in place, and send instructions to the operating mechanism to achieve gear shifting. In the present invention, without changing the overall layout of the existing AMT and DCT, it only needs to change the control cover assembly and add a control module to realize automatic gear shifting.

Description

technical field [0001] The invention relates to a technology in the field of automobile transmissions, in particular to an automatic shifting mechanism of a transmission. Background technique [0002] With the rapid development of transmissions, there are more and more design requirements for electric shifting mechanisms. Both AMT and DCT can apply electric shifting technology. However, the structure of automatic transmissions is more complicated than that of ordinary transmissions, and it is easy to appear out of sync during acceleration. , Frustrated situation, low transmission efficiency, due to the use of hydraulic control, the leakage of hydraulic oil will cause pollution to the environment. AMT is prone to the problem of low shifting stability, while DCT has a relatively small technical popularity and high production costs. Contents of the invention [0003] Aiming at the above-mentioned deficiencies in the prior art, the present invention proposes an automatic shif...
