Abstract

The invention discloses a speed transforming transmission device for vehicles. The speed transforming transmission device for the vehicles comprises a mechanical transmission module, a hydraulic transmission module and a device shell; the mechanical transmission module comprises a first shaft, a second shaft, a third shaft, a transfer gear, a second shaft driven gear, a low gear driving gear, a high gear driving gear, a third driven gear, a low gear driven gear, a high gear driven gear, a first adaptor, a low gear clutch and a high gear clutch; the hydraulic transmission module comprises a hydraulic pump, a pump shaft, a pump shaft gear, a hydraulic motor, a motor shaft, a motor shaft first gear, a motor shaft second gear and a second adaptor; and through the mutual operation of the mechanical transmission module and the hydraulic transmission module, when speed transforming transmission is realized, speed transforming transmission requirements of three transmission modes of pure mechanical transmission, pure hydraulic transmission and hydraulic and mechanical series connection composite transmission can be realized, so that the speed transforming transmission process has the characteristics of both having mechanical transmission and hydraulic transmission to adapt the speed transforming transmission requirements of different types of the vehicles.

Description

technical field [0001] The present invention relates to a transmission, in particular to a variable speed transmission for a vehicle. Background technique [0002] The variable speed transmission has various structures and adopts different power transmission methods, but at present, mechanical and hydraulic transmission methods are the most common. [0003] Mechanical transmission utilizes a system consisting of various mechanical components to transmit power. Mechanical transmission has the characteristics of high transmission reliability, high efficiency, and can realize stepped or continuously variable transmission. However, the mechanical transmission system has a low degree of flexibility in structural layout, and it is easy to cause transmission instability and a sharp drop in transmission efficiency when performing mechanical stepless transmission. And other issues. [0004] Hydraulic transmission is the use of a system consisting of hydraulic pumps, hydraulic motor...
