Abstract

The invention discloses a double-cavity hydraulic retarding device integrated at the bottom of an engine. The double-cavity hydraulic retarding device comprises a hydraulic retarder and a control unit, wherein the hydraulic retarder is installed at the bottom of the engine and provided with a retarding working cavity, and the hydraulic retarder further comprises a concentrated output shaft, an inlet pipeline, an outlet pipeline, a pump, a reflux pipeline, an inlet throttle valve and an outlet throttle valve. The hydraulic retarder is provided with two sets of moving wheel and fixed wheel devices which are arranged in the retarding working cavity, and each set of moving wheel and fixed wheel device comprises a moving wheel and a fixed wheel. An engine crankshaft is movably connected with the concentrated output shaft through a first transmission device, a master clutch is arranged between the first transmission device and the concentrated output shaft, and an auxiliary clutch is arranged between the moving wheel of the second set of moving wheel and fixed wheel device and a corresponding second transmission device. The double-cavity hydraulic retarding device takes an engine cooling agent as a working medium and can eliminate no-load loss, improve low-speed performance and provide effective retarding and braking functions.

Description

technical field [0001] The invention relates to a double-cavity hydraulic retarder integrated at the bottom of an engine, which belongs to the technical field of vehicle auxiliary braking. Background technique [0002] When the vehicle is under continuous braking for a long time, high-intensity braking or frequent braking, the temperature of the brake disc or brake drum will increase significantly, resulting in a decrease in the friction factor, aggravated wear, and partial or even complete loss of braking performance. Dangerous thermal recession phenomenon. Although the application of anti-lock brake system (ABS) and electronic brake force distribution system (EBD) has improved the stability and reliability of vehicle braking, they have little effect on the thermal fading phenomenon of brakes. At present, many countries including my country have clearly stipulated that passenger cars and trucks above a certain specification must be equipped with auxiliary braking devic...
