Transmission shifting mechanism for all-electric cars

Abstract

The invention relates to a transmission shifting mechanism for all-electric cars. According to the technical scheme, the transmission shifting mechanism mainly comprises a shifting motor, linear bearings, a shift fork shaft, a triple-cone synchronizer, a self-locking pin, a shift fork, a shift block, a shift shaft, a buffer, an angle sensor and the like. The buffer is connected with the shifting motor. The shift shaft is mounted on the buffer in a connected manner through splines. Two ends of the shift shaft are provided with the angle sensor and the shift block respectively. An oil seal is disposed between the angle sensor and the shift block. The shift block is inserted into a shift fork hole. The shift fork is connected with the shift fork shaft through the pin. The shift fork shaft is connected to front and rear shells through the linear bearings. The shift fork is inserted into a gear ring of the triple-cone synchronizer. The transmission shifting mechanism has the advantages that shifting force is small, shifting is stable, shifting time is short, and accordingly ECT shifting is higher in quality and reliability.

Description

technical field [0001] The invention relates to a gear shifting mechanism of a pure electric car transmission. Background technique [0002] As we all know, with the world's energy crisis and environmental protection issues becoming increasingly prominent, the automobile industry is facing severe challenges: on the one hand, oil resources are in short supply, and automobiles consume a lot of fuel, and the rising number of automobiles has exacerbated this contradiction; The extensive use of aggravated environmental pollution. With the continuous increase of the dual pressure of resources and the environment, the development of new energy vehicles has become the direction of the development of the automobile industry. Among them, the development of electric vehicles is the most important, but now the transmission of pure electric vehicles shifts gears. The mechanism generally adopts a single-taper lock ring synchronizer, which has a large shifting force, long shifting time, an...

[0002] As we all know, with the world's energy crisis and environmental protection issues becoming increasingly prominent, the automobile industry is facing severe challenges: on the one hand, oil resources are in short supply, and automobiles consume a lot of fuel, and the rising number of automobiles has exacerbated this contradiction; The extensive use of aggravated environmental pollution. With the continuous increase of the dual pressure of resources and the environment, the development of new energy vehicles has become the direction of the development of the automobile industry. Among them, the development of electric vehicles is the most important, but now the transmission of pure electric vehicles shifts gears. The mechanism generally adopts a single cone lock ring synchronizer, which has a large shifting force, long shifting time, and difficult shifting.
