Gearbox based on hydraulic transmission

Abstract

The invention belongs to the technical field of transmissions, and particularly relates to a gearbox based on hydraulic transmission. The gearbox comprises two torque hydraulic conversion mechanisms, a first liquid duct, a gearbox body, a driving gear, a transmission gear, a base and a second liquid duct, the torque hydraulic conversion mechanisms convert between rotation of a transmission shaft and reciprocating flow of liquid, and when the torque hydraulic conversion mechanisms are in matched use, torque transmission effect of the transmission shaft in complex spatial distribution can be realized; the gearbox is designed to have three gears, and three transmission gears and one driving gear are meshed; the driving gear is mounted on a combination base which can move transversely and longitudinally, and the driving gear moves along a plane of the base to selectively drive one of the three transmission gears to realize gear shifting. The liquid duct is connected with the transmission shaft to separate out a power input shaft in the gearbox, mounting flexibility of the gearbox is improved, and the gearbox has a good application prospect.

Description

Technical field [0001] The invention belongs to the technical field of gearboxes, in particular to a gearbox based on hydraulic transmission. Background technique [0002] At present, the positions of the power input shaft and the output shaft in the automobile gearbox are relatively fixed, and a moving transmission gear is added between the two shafts, and the movement of the transmission gear realizes the speed change of the gearbox. The gearbox includes the input shaft, the output shaft and the transmission structure between the two, resulting in a large volume of the entire gearbox. When installing, it is often forced to determine the installation position first due to space constraints, and then because of the distance between the power source and the gearbox. It should not be too large, and the position of the gearbox determines the position of the power source, and then other equipment is installed; the position of the gearbox and the power source basically determines...

The gearbox includes the input shaft, the output shaft and the transmission structure between the two, resulting in a large volume of the entire gearbox. When installing, it is often forced to determine the installation position first due to space constraints, and then because of the distance between the power source and the gearbox. It should not be too large, and the position of the gearbox determines the position of the power source, and then other equipment is installed; the position of the gearbox and the power source basically determines the structural layout of the entire product, which often causes designers to have certain differences in the internal structure of the product. Trade-offs, the internal structural layout of the product is very likely not the optimal structural layout
