Problems solved by technology

At present, the fixed-axis gear train hydraulic transmission that also has a multi-gear structure, such as the "power transmission hydraulic transmission" disclosed in CN2599318Y, but the multi-gear transmission usually adopts a transmission structure of more than five shafts. different shafts, which makes the size of the transmission larger, so the application occasions are subject to certain restrictions

Abstract

The invention relates to automobile dead axle train hydrodynamic drive transmission. It is formed by hydrodynamic torque converter and transmission. The former includes dynamic force coupling, locking clutch, runner, impeller, oil pump, idler pulley seat, and input shaft. The latter includes driving shaft, each driving gear, output shaft, gear shift sleeve, and reverse shaft and gear. It has the advantages reasonable structure and convenient installation.

Description

technical field [0001] The invention relates to a hydraulic transmission for a motor vehicle, in particular to a hydraulic transmission transmission of a fixed axle wheel system for an automobile. Background technique [0002] There are two main types of transmissions in automobiles: mechanical transmissions and hydromechanical transmissions. The mechanical transmission is complicated to operate. For a car that needs to stop, start and accelerate frequently, the driver must change gears frequently, which is labor-intensive, and the mechanical transmission is a rigid transmission with a step change, and the vibration and impact are relatively large during driving. , poor ride comfort. For the hydromechanical transmission, one is a planetary gear transmission, which can obtain an appropriate number of gears through fewer planetary rows, and has the advantages of compact structure and light weight. But there are also defects such as complex process and high manufacturing cost...
