Abstract

The invention provides a rear-mounted three-level gearbox assembly with double shifting forks. The rear-mounted three-level gearbox assembly comprises a gearbox housing; an input shaft, an angle gear shaft and a middle shaft are disposed in the gearbox housing; the input shaft is sequentially provided with first driving teeth and second driving teeth; medium-low speed gear transition teeth, medium speed gear middle teeth and low speed gear middle teeth are disposed on the middle shaft; the input shaft is in key joint with a medium-high speed gear clutch which is provided with the medium-high speed gear shifting fork; the middle shaft is in key joint with a low speed gear clutch which is provided with the low speed gear shifting fork; a low speed gear shifting fork shaft is disposed on the low speed gear shifting fork; a medium-high speed gear shifting fork shaft is disposed on the medium-high speed gear shifting fork; first grooves are formed in the outer side of the low speed gear shifting fork shaft; second grooves are formed in the outer side of the medium-high speed gear shifting fork shaft; the first grooves and the second grooves are each provided with a shifting fork shaft control mechanism. The gear shifting structure is reasonable in design, three-level speed changing is achieved, and the requirements for running with heavy load and fast running with light load are met.

Description

technical field [0001] The invention belongs to the field of transmissions, in particular to a rear-mounted three-stage transmission assembly with double shift forks. Background technique [0002] At present, the demand for the load capacity of tricycles has increased, and the load capacity of tricycles has increased from 0.5 tons to 2.5 tons. The increase in load requires not only an increase in engine power and output torque, but also an increase in the requirements for the variable speed and torque capacity of the transmission system. It is difficult for the transmission to meet the requirements of running fast under heavy loads and running fast under light loads without excessively increasing the engine displacement. Moreover, the structure of the shift fork is also crucial, and the existing design of the shift fork structure is unreasonable and needs further improvement. Contents of the invention [0003] In view of the above-mentioned shortcomings of the prior art, ...
