Embodiment Construction

[0012] Examples, see attached Figure 1~4 , the air inlet 1-2 of the electromagnetic air proportional valve is arranged on the left side above the rear cover 1 for enhancing the braking performance of the hydraulic retarder, and the first air passage 1 is arranged on the right side of the air inlet 1-2 -3, the second gas path 1-5, the third gas path 1-6. The first air passage 1-3 is wave-shaped and the right end communicates with the second air passage 1-5. The side wall of the first air passage 1-3 is provided with a ventilation groove 1-4, and at the same time passes through the ventilation groove 1-1- 4 communicates with the second air passage 1-5, and the left end of the first air passage 1-3 communicates with the air inlet 1-2 after being combined with the rear cover 1 and the middle cover. The second air passage 1-5 is still wave-shaped and the left end communicates with the left end of the third air passage 1-6. The third air passage 1-6 is straight and closed at the r...

Abstract

The invention belongs to automobile parts, and particularly relates to a rear cover for enhancing the braking performance of a hydraulic retarder. An air inlet of an electromagnetic air proportional valve is formed in the left side of the upper portion of the rear cover, and a first air channel, a second air channel and a third air channel are formed in the right side of the air inlet. The included angle between the center line of a first oil channel section and the horizontal direction is beta, a second oil channel section is vertically upward, and the included angle between the center line of a third oil channel section and the vertical direction is alpha. An oil storage chamber is arranged at the top end of a lubricating oil channel and communicates with an oil suction port of a lubricating oil pump, and the lubricating oil channel and an oil inlet channel are surrounded by the lubricating oil channel and the oil inlet channel to form an oil outlet channel. A one-way valve is arranged in a one-way valve seat hole, the one-way valve seat hole is communicated with a middle cover oil outlet channel through the one-way valve, and a heat exchanger oil inlet hole is formed in the lower end of the oil outlet channel. The structure is compact, the function integration level is high, oil liquid entering a working cavity of the hydraulic retarder can be effectively prevented from containing a large amount of air, and the continuous stability of the braking performance of the hydraulic retarder is guaranteed.

Description

technical field [0001] The invention belongs to auto parts, in particular to a back cover for enhancing the braking performance of a hydraulic retarder. Background technique [0002] The hydraulic retarder is a kind of oil that participates in the work through the agitation of the stator and the rotor. The rotor throws the oil to the stator, and the stator throws the oil to the rotor, and then exerts a reaction force on the rotor to prevent the rotor from rotating. The effect of vehicle deceleration. Hydraulic retarder control is to use compressed air to hydraulically pump the oil in the fuel tank into the working chamber to participate in the work, and the air in the working chamber will be discharged at this time. If there is more air mixed in the air in the working chamber and the oil, it will seriously cause insufficient braking force of the hydraulic retarder, threatening the driving safety of the vehicle. Contents of the invention [0003] The purpose of the presen...
