Embodiment 1

[0018] Such as figure 1 , 2 As shown, the present invention discloses an oil-gas combined parallel hydraulic retarder device for automobiles. The hydraulic retarder is installed on the rear side of the vehicle gearbox and driven by the speed-up gear of the gearbox, including a signal receiving end, a controller 3. Proportional valve 4, gas storage tank 5, hydraulic retarder and sensor components, manual switch 1 and brake air pressure switch 2 are connected to controller 3 through signal lines, and one end of proportional valve 4 is connected to hydraulic retarder. The other end is connected with the gas storage tank 5, and receives the control signal of the controller 3 through the signal line, and the sensor assembly is installed on the peripheral side of the hydraulic retarder.

[0019] The hydraulic retarder includes a working chamber, an oil storage chamber 6 and a cooler 10. The oil storage chamber 6 is connected to the proportional valve 4. The working chamber is forme...

Abstract

The invention relates to machine design and manufacturing and discloses an oil-gas combined parallel hydraulic retarder device for an automobile. The oil-gas combined parallel hydraulic retarder device for the automobile comprises a signal receiving end, a controller, a proportional valve, a gas storage tank, a hydraulic retarder and a sensor assembly. The separation technique that a rotor pump driving wheel is disengaged from a stator pump resisting wheel is adopted for the oil-gas combined parallel hydraulic retarder, so that an unnecessary load generated by air to the automobile is reduced when the oil-gas combined parallel hydraulic retarder does not operate; the parallel hydraulic retarder is connected with an auxiliary box of an automobile transmission and connected with a rotating shaft of the automobile in parallel; the design structure is simple, and installation and maintenance are convenient; the die-casting formation design is adopted for an important shell structure, deformation is small, the wall thickness is uniform, the strength is high, and the heat dissipation effect of the oil-gas combined parallel hydraulic retarder device is good; and the weight of the oil-gas combined parallel hydraulic retarder device is only about 50 KG, the torque generated in unit weight is large, and requirements of large slopes and large-tonnage vehicles in Chine can be met.

Description

technical field [0001] The invention relates to mechanical design and manufacture, in particular to an oil-gas combined parallel hydraulic retarder device for automobiles. 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 stator of the hydraulic retarder is also the retarder housing, which is connected to the rear end of the transmission or the frame, and the rotor is connected to the transmission shaft through a hollow shaft, and blades are cast on the rotor and the stator. When working, apply pressure to the oil pool with the help of the control valve to make the working fluid fill the working chamber between the rotor...
