The invention discloses a gear selecting and shifting structure, a transmission and a vehicle. The gear selecting and shifting structure is provided with multiple gears and comprises a shell, a driving shaft, a gear selecting assembly and a gear shifting assembly. At least part of the driving shaft is arranged in the shell, the driving shaft is provided with a gear selecting and shifting sleeve, the gear selecting and shifting sleeve has a plurality of running positions, and each running position forms the corresponding gear. The gear selecting assembly comprises a grooved wheel and a grooved wheel stirring pin, the grooved wheel is meshed with the grooved wheel stirring pin, and the grooved wheel abuts against the gear selecting and shifting sleeve so as to drive the gear selecting and shifting sleeve to change the running position. The gear shifting assembly comprises a gear shifting fork, a gear shifting lead screw and a lead screw nut, the lead screw nut is arranged on the gear shifting lead screw in a penetrating mode, the lead screw nut is arranged at one end of the gear shifting fork, and the other end of the gear shifting fork abuts against the gear selecting and shifting sleeve. In this way, the driving shaft is in abutting connection with the gear selecting and shifting structure, the gear selecting and shifting structure can adjust and control gear shifting, the gear shifting accuracy of the gear selecting and shifting structure is improved, and gear replacement of the driving shaft can be more stable and reliable.
Description
technical field [0001] The invention relates to the technical field of vehicles, in particular to a gear selection structure, a transmission and a vehicle. Background technique [0002] In the prior art, a shifting structure is provided in the transmission of the vehicle to change gears, so that the vehicle can run more efficiently and smoothly. The mature structures of shifting structures in the prior art are ball screw type, worm gear type, gear transmission type and rack and pinion type. The collocation of the above-mentioned types is likely to cause inaccurate gear shifting, thereby reducing the performance of the transmission. At the same time, this operation method is relatively complicated, which makes the user's use of the transmission less expensive. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, an object of the present invention is to provide a selector shift s...
