Abstract

The invention relates to the field of mechanical design and manufacturing, and discloses an independently mounted hydrodynamic retarder. The independently mounted hydrodynamic retarder comprises a hydrodynamic retarder cover, a rotor pump driving wheel, a stator pump driven wheel, a spline shaft, a hydrodynamic retarder shell, an electromagnetic proportional valve and a heat exchanger. By means ofoptimal structure design, the technology of separating the driving wheel and the driven wheel is adopted, and no-load loss generated when the retarder stops working is greatly reduced; and semi-spherical design is adopted by the overall appearance, stress is even, the heat radiating effect of the retarder is improved, and the use performance of the retarder is greatly improved. Aiming at the problem about medium oil recycling of an oil storage chamber of the retarder shell and overheating of the electromagnetic proportional valve, a corresponding solving design structure is provided, the oilreplacing frequency of the retarder is effectively reduced, and the heat exchange time of the retarder is effectively shortened; and the work efficiency is improved, cost is reduced, the service lifeof the retarder is prolonged, and the performance of the retarder is improved.

Description

technical field [0001] The invention relates to the field of mechanical design and manufacture, in particular to an independently installed 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-pressure air in the ...
