Description
Technical field
The utility model relates to automobile clutch technical field, particularly a kind of clutch coupling structure for pressure test.
Background technology
At present, automobile clutch in maintenance process, overhaul transmission components clutch coupling time, friction disc due to clutch coupling is wearing detail, and clutch coupling frequency of maintenance is high, after on the clutch device sometimes fixed to variable-speed shaft, occur that clutch coupling seal is poorly sealed, cause dismounting again.Because when overhauling, clutch coupling, not through pressure testing inspection, exists uncertain, torque converter is installed to and occurs after on car that indivedual gear power is little, the fault such as to burn to death without gear, clutch coupling even sometimes, affects work efficiency.
Utility model content
Technical problem to be solved in the utility model is, for the deficiencies in the prior art, provides a kind of clutch coupling structure for pressure test, to reach pressure testing inspection before the clutch device overhauled mixes variable-speed shaft, distinguishes the object whether product is qualified.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of clutch coupling structure for pressure test, comprise and be pressed on the upper and lower end face of clutch coupling endoporus respectively by the upper press cover of clutch coupling endoporus shutoff, lower cover, described upper press cover is connected by screw rod with between lower cover, and described lower cover is provided with pressurized air inlet suction port.
Described screw rod is stretched out by lower cover and passes upper press cover and stretches out, and the bar wall of its external part is provided with external thread, and nut is connected on external thread and locks.
In nut lock state, upper press cover, form inlet chamber between lower cover and clutch coupling endoporus, described inlet chamber is communicated with clutch coupling working oil chamber by air admission hole.
The described upper press cover end face be pressed on clutch coupling endoporus is extended with the boss matched with clutch coupling endoporus aperture and forms step surface structure, and the described lower cover end face be pressed on clutch coupling endoporus is extended with the boss matched with clutch coupling endoporus aperture and forms step surface structure.
The end face that described upper press cover is pressed in end face on clutch coupling endoporus, lower cover is pressed on clutch coupling endoporus is respectively equipped with seal groove, is provided with O-ring seal in described seal groove.
The utility model adopts said structure, has the following advantages: 1, through pressure testing, effectively controls the qualification rate of clutch coupling, thus ensure that the quality of follow-up assembling; 2, the step surface structure of upper press cover, lower cover ensure that the easy for installation of upper press cover, lower cover; 3, O-ring seal plays sealing effectiveness.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail;
Fig. 1 is the structural representation that the utility model fills pressure testing on the clutch;
Fig. 2 is structural representation of the present utility model;
In Fig. 1 ~ Fig. 2,1, upper press cover; 2, lower cover; 3, screw rod; 4, pressurized air inlet suction port; 5, nut; 6, inlet chamber; 7, working oil chamber; 8, O-ring seal; 9, friction disc catch spring; 10, clutch friction plate; 11, clutch hub; 12, piston.
Embodiment
A kind of clutch coupling structure for pressure test as shown in Fig. 1 ~ Fig. 2, comprise and be pressed on the upper and lower end face of clutch coupling endoporus respectively by the upper press cover 1 of clutch coupling endoporus shutoff, lower cover 2, be connected by screw rod 3 between upper press cover 1 with lower cover 2, lower cover 2 is provided with pressurized air inlet suction port 4.
Screw rod 3 is stretched out by lower cover 2 and passes upper press cover 1 and stretches out, and the bar wall of its external part is provided with external thread, and nut 5 is connected on external thread and locks.Upper press cover 1 and lower cover 2 are pressed on the upper and lower end face of clutch coupling endoporus by nut 5, are sealed by clutch coupling.At nut 5 locking state, upper press cover 1, form inlet chamber 6 between lower cover 2 and clutch coupling endoporus, inlet chamber 6 is communicated with clutch coupling working oil chamber 7 by air admission hole.Upper press cover 1 end face be pressed on clutch coupling endoporus is extended with the boss matched with clutch coupling endoporus aperture and forms step surface structure, lower cover 2 end face be pressed on clutch coupling endoporus is extended with the boss matched with clutch coupling endoporus aperture and forms step surface structure, and expediently gland 1, lower cover 2 compress.
The end face that upper press cover 1 is pressed in end face on clutch coupling endoporus, lower cover 2 is pressed on clutch coupling endoporus is respectively equipped with seal groove, is provided with O-ring seal 8, plays sealing function in seal groove.Clutch coupling comprises friction disc catch spring 9, clutch friction plate 10, clutch hub 11, piston 12.
Pressurized air is filled with from pressurized air inlet suction port 4, pressurized air enters inlet chamber 6 and enters clutch coupling working oil chamber 7 by air admission hole, promotes piston knee-action, checks pistons work dirigibility, with or without gas leak phenomenon, whether the clutch coupling after inspection maintenance is qualified.Through pressure testing, effectively control the qualification rate of clutch coupling, thus ensure that the quality of follow-up assembling.This structure for pressure test is applicable to body two ends to seal, and utilizes pressurized air to carry out pressure testing experiment to replace fluid.
Pressure testing process is: want to carry out pressure testing to clutch coupling, clutch coupling inlet end upper and lower port must be sealed.A set of according to clutch coupling hole size processing upper and lower cover plates, upper and lower cover plates will be pressed on the upper and lower end face of clutch coupling endoporus by middle screw rod.Consider that upper and lower cover plates installs accurate positioning in pressure testing process, will process a positioning step by upper and lower cover plates according to clutch coupling hole size.Consider the sealing of upper and lower cover plates, a seal groove must be processed, to install O-ring seal in upper and lower cover plates.Consider the harmony of clutch coupling pressure testing air inlet, process an intake interface, gases at high pressure are delivered to clutch coupling inside near clutch coupling inlet end.When not installing clutch disc pressure testing, gas to be given slowly, being unlikely to clutch plunger compression to exceed its stroke range like this, and its seal is damaged.0.7 ~ 0.9MPa voltage stabilizing test to be carried out, to detect the sealing situation of clutch coupling under constant air pressure at clutch coupling pressure testing end.
By reference to the accompanying drawings the utility model is exemplarily described above; obvious the utility model specific implementation is not subject to the restrictions described above; as long as have employed the various improvement that the technical solution of the utility model is carried out; or directly apply to other occasion, all within protection domain of the present utility model without improving.
