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

Embodiment 1

[0019] like Figure 1-3 As shown, the present invention discloses an air inlet structure of a hydraulic retarder ventilator. The ventilator is a rectangular structure, and the upper surface of the ventilator is provided with two sets of circular openings connected with the hydraulic retarder shell. There are two sets of circular openings connected to the electromagnetic proportional valve on the lower surface, several circular openings are opened on the side of the ventilation device, two sets of air inlets are arranged in the ventilation device, and the upper The circular openings on the surface and the circular openings on the sides communicate with each other to form an airway structure.

[0020] The air inlets are respectively a group of cross-shaped structure air inlets 1 and a group of T-shaped structure air inlets 2. The air inlets all use circular openings on the upper surface of the ventilation device as air inlets 3, and the air inlets on the side of the ventilation ...

Abstract

The invention relates to the field of mechanical design and manufacture, and discloses an air inlet structure of a hydraulic retarder ventilator. The upper surface of the ventilator of the present application is connected to the air inlet of the retarder cover, and the lower surface is connected to the air outlet of the electromagnetic proportional valve. , the airway structure is designed with three rotation angles of 90°. When the retarder is not working, the exhaust gas will collide at a right-angle flow rate. There is a storage room for the retarder. When passing through this channel, three collisions and separations are carried out at three right-angle turns. The retarder medium oil and the oil discharged from the retarder gas at high temperature are recovered, which increases the service life of the retarder. and performance.

Description

technical field [0001] The invention relates to the field of mechanical design and manufacture, in particular to an air inlet structure of a hydraulic retarder ventilation device. 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-...
