Hydraulic retarder independent mounting structure

Abstract

The invention relates to the field of machine design and manufacture and discloses a hydraulic retarder independent mounting structure, comprising a fixing beam, connectors and a mounting frame; such mounting structure may be mounted between an automobile girder and a double transmission shaft connection independently; such mounting mode is different from an existing retarder mounting mode; in installation of present existing hydraulic retarders at home and abroad on an automobile transmission case, matching with an auxiliary case of the transmission case is required, and a distance between a drive axle and the auxiliary case necessarily greater than 450 mm is also required; particularly in parallel installation mode, a distance between girders is required to be greater than 750 mm; the connection mode of the independent mounting structure according to the application to a vehicle need not be connected to the auxiliary case of the transmission case, and the distance between the drive axle and the auxiliary case is not necessarily limited; installation is suitable for girder width of 500 mm and above; such mounting structure allows hydraulic retarders to be mounted in mass vehicles at home and abroad; the blank of hydraulic retarders at home and abroad is made up, and life safety and property safety of all passengers and drivers are guaranteed.

Description

technical field [0001] The invention relates to the field of mechanical design and manufacture, in particular to an independent installation structure of a hydraulic retarder. Background technique [0002] Hydraulic retarder is also called hydraulic deceleration device. Cars use exhaust brake when going down a long slope. Although they can receive a good braking effect, for heavy vehicles with a larger tonnage, the exhaust brake effect is limited. Therefore, hydraulic deceleration retarders are installed on heavy vehicles equipped with hydromechanical transmission. [0003] The hydraulic retarder is a reducer for large trucks. It converts the kinetic energy of the transmission shaft into the internal energy of the oil through the agitation of the oil, and then dissipates heat through the heat exchanger to achieve the retarding effect. When the oil in the fuel tank is pressed into the working chamber by the high-pressure air, the hydraulic retarder works. When the high-pres...

AI Technical Summary

Problems solved by technology

When the oil in the fuel tank is pressed into the working cavity by high-pressure air, the hydraulic retarder works. When the high-pressure air in the fuel tank is discharged, the oil returns to the oil tank and the hydraulic retarder stops working, while the hydraulic retarder in the prior art When the oil tank for the hydraulic retarder is insufficient, part of the air will leak into the working chamber, which will affect the work of the hydraulic retarder
