Hydrodynamic transmission for light vehicle

Abstract

The invention relates to a hydrodynamic transmission for a light vehicle. An oil pump driving sleeve and a supporting shaft are installed on a box body; an oil pump arranged in the box body is connected with the oil pump driving sleeve; a power take-off window is formed in the position, at the horizontal part of an input shaft, of the box body; a connection gear arranged on a guide wheel base in a sleeving mode is engaged with an oil pump connection gear arranged on the pump driving sleeve through two power takeoff gears on the supporting shaft; a first shaft and a second shaft are each provided with a wet clutch and a corresponding driving gear; driven gears installed on the first shaft and the second shaft are engaged with two input gears of the input shaft correspondingly; all driving gears on the first shaft and the second shaft are engaged with an output shaft gear, a high-gear output gear and a low-gear output gear on an output shaft correspondingly; and a reverse-gear clutch Kr and a reverse-gear driving gear on a reverse-gear shaft are engaged with the wet clutch on the first shaft and the low-gear output gear correspondingly, and are matched with a lockup clutch, so that output with six forward gears and one reverse gear is achieved. The hydrodynamic transmission is ingenious and compact in structure and flexible in operation, has the multiple gears, and can adapt to different working conditions of the light vehicle.

Description

technical field [0001] The invention relates to a hydraulic transmission for light vehicles, belonging to the technical field of hydraulic transmissions for light vehicles. Background technique [0002] The transmission of general automobile mainly has two kinds of mechanical transmission and hydraulic mechanical transmission. The mechanical transmission is complicated to operate. For a car that needs to stop, start and accelerate frequently, the driver must shift 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. The wet multi-disc clutch is controlled by an electro-hydraulic valve to realize gear shifting. The hydraulic mechanical transmission has the advantages of good manufacturing process and high transmission efficiency due to the use of external meshing gears for gear shifting transmission. As for the hydromechan...

AI Technical Summary

Problems solved by technology

The automatic transmission of a passenger car cannot be installed due to insufficient power; the automatic transmission of a heavy-duty vehicle has an unsuitable power range and is too large to be installed

Furthermore, due to the common insensitivity of the existing hydraulic transmissions of the same type, it is difficult to use when switching between different working conditions, and the use is labor-intensive.
