Oil chamber cover for parallel connection of hydrodynamic retarder

Abstract

The invention relates to the field of mechanical design and manufacturing, and discloses an oil chamber cover for parallel connection of a hydrodynamic retarder. Through structural design, a transition area of the oil chamber cover serves as a buffer transition area of high-temperature and high-pressure oil for a hydrodynamic retarder working cavity and a heat exchanger; an elliptic structure is adopted and stabilized through reinforcing ribs, so that the high-temperature and high-pressure oil cannot directly dash into the heat exchanger, and the performance of the heat exchanger is protected; the reasonably designed oil chamber cover is integrated with such functional parts as an oil way structure, an oil return chamber, a transition area and an oil collecting chamber; and the reinforcing ribs are staggered on the inner surface of the oil chamber cover to promote the high-temperature and high-pressure bearing capacity of the oil chamber cover.

Description

technical field [0001] The invention relates to the field of mechanical design and manufacture, in particular to a cover for an oil chamber of a parallel 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-pressu...

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
