Detailed Description
The invention is described in further detail below with reference to the following figures and specific examples:
for convenience only, in the following description, specific directional terms are used, reference is made to the corresponding drawings, and no limitation of the present invention is intended, and when changes are made in the direction defined in the drawings, the direction in which the words are used should be construed as corresponding different directions.
As shown in fig. 1, 3, and 4, the bottom pull clutch cylinder is mounted directly below the transmission case 13 and at the front end of the clutch case 14. The cylinder 1, the piston 3 and the piston rod 4 are arranged in the cylinder.
A guide plate 5 is arranged in the cylinder 1 along the radial direction, and a gas working chamber is arranged between the guide plate 5 and the front end cover 11 of the cylinder; the guide plate 5 is provided with a vent hole 51 and a mounting hole 52; the piston 3 is arranged in the gas working chamber in a sliding manner, a sealing ring is arranged between the piston and the cylinder 1, and the gas working chamber is divided into a normal pressure chamber 15 and a high pressure chamber 16; the piston rod 4 is disposed in the mounting hole 52 to assist the sliding of the piston 3.
An exhaust passage 2 is opened in the side wall of the cylinder 1. The atmospheric pressure chamber 15 is communicated with the exhaust passage 2 through a first exhaust hole 21 formed in the inner wall of the cylinder 1, and the first exhaust hole 21 is located at the joint of the front end cover 11 of the cylinder and the side wall of the cylinder 1. The high-pressure chamber 16 is communicated with the exhaust channel 2 sequentially through the vent hole 51, the exhaust electromagnetic valve 6 and the second exhaust hole 22 arranged on the inner wall of the cylinder 1, the second exhaust hole 22 is positioned at the joint of the rear end 12 of the cylinder and the side wall of the cylinder 1, and the exhaust electromagnetic valve 6 is a two-inlet and two-outlet electromagnetic valve. An air outlet hole 23 is formed in the outer wall of the cylinder 1 where the exhaust channel 2 is located; the air outlet 23 is provided with an air pipe joint 8, and the air pipe joint 8 is connected with an exhaust pipe 9 through a sealing element. The side surface of the transmission shell 13 opposite to the air outlet 23 is provided with an air pipe clamp 10, the exhaust pipe 9 is fixed in the air pipe clamp 10 after bypassing the transmission shell 13 upwards (around the transmission shell 3/4), and the opening of the exhaust pipe 9 is arranged downwards to prevent accumulated water from entering the exhaust pipe 9.
The working principle of the utility model is as shown in figure 2:
the atmospheric chamber 15 is open to the atmosphere, while the high-pressure chamber 16 is filled with high-pressure gas during operation, and the high-pressure chamber 16 is open to the atmosphere via the exhaust solenoid valve 6. When the piston 3 moves leftwards, the exhaust electromagnetic valve 6 is closed, the high-pressure chamber 16 is continuously filled with high-pressure gas, and the air in the normal-pressure chamber 15 is continuously exhausted through the first exhaust hole 21; when the piston 3 moves to the right, the exhaust solenoid valve 6 is opened, and the high-pressure gas is continuously exhausted through the second exhaust hole 22, at this time, although the cavity of the normal pressure chamber 15 becomes larger as the piston 3 moves to the right, because the high-pressure gas is exhausted from the high-pressure chamber 16, compared with the air intake of the normal pressure chamber 15, the exhaust amount of the high-pressure chamber 16 is much larger than that of the normal pressure chamber 15, and therefore, even when the piston 3 moves to the right, the exhaust hole 23 is still in an exhaust state. Therefore, adopt the utility model discloses end draws formula clutch slave cylinder no matter piston 3 is the motion left or right, can not arouse external gas to inhale cylinder 1, can effectively avoid the vehicle to end to draw formula clutch slave cylinder 1 to intake when wading into water to solve the trouble that end draws formula clutch slave cylinder and intakes and arouse, improved the reliability of mechanical type automatic transmission end draws formula clutch slave cylinder.
