Description

Automatic exhaust clutch slave cylinder structure Technical Field The invention belongs to the technical field of automobile transmissions, and particularly relates to an automatic exhaust clutch slave cylinder structure. Background The clutch slave cylinder is an important component of a clutch control system of the transmission, one end of the clutch slave cylinder is connected with a clutch pedal and an oil pipe of the clutch master cylinder, and the other end of the clutch slave cylinder is connected with a separation support arm. When the clutch pedal starts to work, pedal force is transmitted to the clutch slave cylinder by the clutch master cylinder, and the clutch slave cylinder works to enable the separation support arm to swing, so that the separation and combination functions of the clutch are realized. Because the clutch slave cylinder is tightly connected with other parts, the clutch master pump is connected with the clutch slave cylinder through an oil way, and the clutch slave cylinder and the oil way are required to be subjected to air release and exhaust after initial assembly and maintenance, the reasonable design of the clutch slave cylinder structure is important. Disclosure of Invention The invention aims to provide an automatic exhaust clutch slave cylinder structure, which effectively solves the exhaust problem of the clutch slave cylinder after initial installation and maintenance, and enables the clutch slave cylinder and an oil way to exhaust more efficiently and rapidly. The clutch slave cylinder structure comprises a clutch slave cylinder body, a front casing shell, a stud, a separation support arm, a separation bearing assembly and a clutch separation finger, wherein one end of the clutch slave cylinder body is connected with a clutch master cylinder through an oil way, the other end of the clutch slave cylinder body is matched with the separation support arm, the separation support arm and a separation bearing assembly central hole are assembled into the front casing shell along a front casing shell guide rail, the clutch separation finger is arranged at one end, far away from the separation support arm, of the separation bearing assembly and is arranged on the front casing shell guide rail, a separation support arm stud ball socket is arranged on the stud ball head, a support arm clip is fixed at the front end of the separation support arm through a mounting hole at the front end of the separation support arm, the support arm clip is used for clamping and fixing the separation bearing assembly, the stud clip is arranged at the middle of the separation support arm, the stud clip is used for clamping the stud, and a bleeder screw is arranged on the clutch slave cylinder body. Further, the clutch slave cylinder body is connected with an oil pipe of the clutch master cylinder through a first branch pipe on the clutch slave cylinder body, a bleeder screw is arranged on a second branch pipe on the clutch slave cylinder body, a part of the bleeder screw, which is leaked outside the clutch slave cylinder body, is provided with an air vent, and the inside of the bleeder screw is of a hollow structure and is connected with an inner cavity of the clutch slave cylinder body and the air vent. Furthermore, the inside of the bleeder screw is provided with an oil-proof breathable film. Further, a rubber gasket is arranged between the joint of the bleeder screw and the clutch slave cylinder body. Compared with the prior art, the invention has the beneficial effects that: 1. the bleeder screw can automatically exhaust gas unidirectionally, does not need to unscrew the bleeder screw, and simultaneously keeps the function of exhausting gas by unscrewing the bleeder screw when necessary. 2. According to the invention, a layer of oil-proof breathable film is newly added inside the air release screw of the clutch slave cylinder, and the air vent is newly added outside the air release screw, wherein the air vent is a one-way air vent for air, and when the clutch slave cylinder and the oil way are exhausted, air passes through the oil-proof breathable film and the air vent in sequence, so that the exhaust is facilitated. 3. The bleeder screw is matched with the rubber gasket for use, plays a sealing role on the matched position of the screw, and reduces the entry of tiny impurities as far as possible. The clutch cylinder and the oil way are more efficient and faster in exhausting.
