The clutch master cylinder is connected to the clutch pedal and connected to the clutch booster through the oil pipe. The function is to collect pedal stroke information and realize the clutch disengagement through the function of booster.
The brake master cylinder, also known as "brake master cylinder" and "brake master cylinder", is the main source of the brake system of the whole vehicle to be matched. The final role is to cooperate with the brake system assembly to brake the whole car. According to different vehicles, it is also divided into two types: air brake master cylinder and oil brake master cylinder. In general, most of the brake master cylinders in passenger cars (such as cars and micro passengers) use oil brake master cylinders, while commercial vehicles Brake master cylinders (such as trucks, tractors, etc.) generally use air brake master cylinders.
The right end of the pressure-building piston 2 and the left end of the boosting piston 3 are provided with an annular guide groove 6, and a guide ring 7 cooperating with the annular guide groove 6 is provided in the annular guide groove 6, the left end of the pressure-building piston 2 and the boosting piston 3 The right end of each is provided with an annular groove 8, the annular groove 8 is sleeved with a sealing ring 9 that cooperates with the annular groove 8, and a pressure building cavity 10 provided on the right side of the pressure building piston 2 The right side of 10 is provided with an oil valve 11 connected to the left side of the pressure-building piston 2 and a return spring 12 connected to the oil valve 11 on the right side. The left side of the return spring 12 abuts the inside of the left end of the cylinder 1. During installation, put the return spring 12 into the cylinder body 1, install the sealing ring 9 and the guide ring 7 into the cylinder body 1 after the pressure piston 2 is installed, and then put the connecting rod 5 into the first connecting rod of the pressure piston 2 The hole 4 is then put into the cylinder 1 after the booster piston 3 is fitted with the sealing ring 9 and the guide ring 4 while ensuring that the connecting rod 5 is introduced into the second connecting rod hole 13 of the boosting piston 3.
When in use, the right end of the booster piston 3 is connected to the push rod. When the clutch pedal is depressed, the pedal force acts on the boost piston 3 through the push rod. At this time, the boost piston 3 and the push rod are on different axes, so the boost piston 3 There is a separating force in the direction of movement and a lateral separating force perpendicular to the direction of movement; the separating force in the direction of movement acts on the pressure-building piston 2 via the connecting rod 5, and the pressure-building piston 2 is only affected by the direction of movement Without the lateral force causing partial wear, which also reduces the friction between the pressure-building piston 2 and the cylinder 1 during the movement, reduces the wear of the pressure-building piston sealing ring 9, and extends Working life, at the same time, because the pressure-building piston 2 is not subjected to lateral outward force, it will not tilt, greatly reducing the failure rate of the clutch master cylinder assembly during the work.
