Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the utility model structure connection diagram.
Fig. 2 is the external electric connection diagram of the utility model controller 13.
The specific embodiment
As shown in Figure 1, the oil circuit of hydrodynamic retarder is made of oil inlet, oil outlet and the relevant oil circuit of pressure oil tank 6, hydrodynamic retarder epitrochoidal chamber 3, water oil heat exchanger 7 successively.Stator 1, rotor 2 and pressure sensor 8 are installed in the hydrodynamic retarder epitrochoidal chamber 3.Be provided with a 3-position-3-way solenoid valve 5 between vent, high-pressure air source A and the atmosphere B of pressure oil tank 6, fuel tank 6 is communicated with 3-position-3-way solenoid valve 5 with tracheae 12.3-position-3-way solenoid valve 5 is connected with controller 13, and 3-position-3-way solenoid valve 5 is accepted controller instruction C.Fuel tank 6 connects between hydrodynamic retarder epitrochoidal chambers 3 atmosphere B and the oil gas check valve 4 to be connected with tracheae 12 by oil gas check valve 4 and communicates.The H Exch 7 that has water inlet G and water outlet H is connected between fuel tank 6 and the hydrodynamic retarder epitrochoidal chamber 3, and H Exch 7 links to each other with oil pipe 11 with retarder epitrochoidal chamber 3.On near near the oil pipe 11 the retarder epitrochoidal chamber 3, epitrochoidal chamber oil temperature sensor 10 is set.Be arranged on pressure sensor 8 in the hydrodynamic retarder epitrochoidal chamber 3, be arranged on the H Exch 7 temperature sensor 9, epitrochoidal chamber oil temperature sensor 10, the signal wire (SW) of gear handle 14,3-position-3-way solenoid valve 5 is electrically connected controller 13 respectively.Controller 13 is gathered the signal F of cooling-water temperature sensor 9 and the signal D of epitrochoidal chamber oil temperature sensor 10 in real time.
The operation different according to chaufeur, gear handle 14 have 1,2,3,4,5 five gear, and wherein 1 grade is the constant speed gear, and 2,3,4,5 to be respectively liquid filled ratio be 25%, 50%, 75%, 100% gear; Gear handle 14 provides gear signal I to controller 13; Acceleration pedal signal J and ABS signal K.The signal E of controller 13 real-time collecting work cavity pressure sensors 8, and with the contrast of the pairing pressure signal of driving switch incoming signal, carry out logic determines, the mode of operation of decision 3-position-3-way solenoid valve 5 is inflation position, suppression or venting position.Vehicle present speed when gear handle 14 is allocated to 1 constant speed retaining can be remembered, and car speed will be controlled near the memory rate, when 14 groups of operating handles after 1, memory can be deleted, normal vehicle operation.When 3-position-3-way solenoid valve 5 is positioned at the exhaust position, high pressure air meeting exhaust to atmosphere in the pressure oil tank 6, have portion of air simultaneously and enter hydrodynamic retarder epitrochoidal chamber 3 by oil gas check valve 4, accelerate the draining speed of oil in the epitrochoidal chamber by pressing mode, thereby realized draining the oil fast of hydrodynamic retarder.
