Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic clutches, in particular to a leakage-proof hydraulic clutch pump. Background Art

[0002] The hydraulic clutch pump, as part of the hydraulic system, is mainly responsible for generating and transmitting pressurized liquid (usually hydraulic oil) to drive the operation of the hydraulic clutch. Its function is to convert mechanical energy into hydraulic energy, thereby realizing remote control and operation of the clutch.

[0003] After searching, the patent with the patent announcement number CN201520310012.4 discloses a hydraulic clutch master pump for automobiles. Although the device is provided with a sealing device at the connection between the oil inlet and the oil inlet joint when in use, the sealing device includes a rubber sleeve and a fixed pressure plate, the rubber sleeve is arranged on the inner wall of the oil inlet, the oil inlet joint is inserted in the rubber sleeve with interference fit, the oil inlet joint is circumferentially extended with an annular limit plate, the fixed pressure plate is pressed on the annular limit plate and locked on the pump body, but the connection between the oil inlet joint and the oil inlet is not tight enough when the device is in use, and it is impossible to ensure that the oil inlet joint will not loosen due to vibration. Vibration is a common phenomenon during the operation of the car, and the design of the hydraulic clutch master pump cannot ensure that the oil inlet joint remains tightly connected under vibration conditions. This may cause the oil inlet joint to gradually loosen during long-term use, thereby affecting the normal operation and performance stability of the hydraulic clutch. Since the connection between the oil inlet joint and the oil inlet is not tight enough, the hydraulic oil may leak from the connection under high pressure. This leakage will not only reduce the working efficiency of the hydraulic clutch, but also pollute the surrounding environment and increase maintenance costs. Utility Model Content

[0004] In view of the deficiencies of the prior art, the utility model provides a leakage-proof hydraulic clutch pump, which solves the problems raised in the background technology.

[0042] Working principle:

[0043] When the oil pump starts to work, it pumps the oil through the rubber hose 6 into the housing 5 of the hydraulic clutch pump. The oil enters through the inlet pipe 504 and passes through the connection between the socket 502 and the joint 7 to ensure that the oil can flow smoothly into the pump body. Under the action of the oil pressure, the piston head 804 receives a backward thrust, which then pushes the push rod 8 backward. The movement of the push rod 8 is connected to the connecting rod 2 through the fixed clamp 801, thereby driving the connecting rod 2 to move together. A spring 803 is arranged at one end of the push rod 8 close to the piston ring 802. Its function is to buffer the sudden impact of the oil pressure on the push rod 8 and protect the internal structure of the pump body from damage. At the same time, the spring 803 can also help the push rod 8 return to its initial position when the oil pressure decreases.

[0044] The connecting rod 2 is in transmission connection with the actuator (such as a clutch) through the connector 1. When the push rod 8 is pushed by the hydraulic pressure, the connecting rod 2 will also move accordingly, and then transmit the power to the actuator through the connector 1 to realize the separation or engagement of the clutch. The setting of the exhaust port 501 allows the air accumulated inside the pump body to be discharged, ensuring that the hydraulic fluid can fill the entire pump body and establish a stable pressure. At the same time, the plugging and bolt 701 fixing method between the connector 7 and the socket 502, as well as the clamp 601 locking and fixing method between the rubber hose 6 and the connector 7, ensure the sealing performance of the pump body and prevent the leakage of hydraulic fluid.
