[embodiment]
For making the purpose of this utility model, technological scheme and advantage more cheer and bright, below by accompanying drawing and embodiment, the utility model is further elaborated.But should be appreciated that, specific embodiment described herein only, in order to explain the utility model, is not limited to scope of the present utility model.In addition, in the following description, omitted the description to known configurations and technology, to avoid unnecessarily obscuring concept of the present utility model.
Consult Fig. 1 and Fig. 2, the utility model embodiment provides a kind of universal joint assembly that Decompression valves is housed, and comprises cross axle axis body 1, is provided with axle journal 2 on cross axle axis body 1, is arranged with axle sleeve 4 on axle journal 3, is provided with Decompression valves 4 on cross axle axis body 1.In the present embodiment, Decompression valves 4 is located at cross axle axis body 1 central position, can certainly be located at other positions.A kind of universal joint assembly that Decompression valves is housed that the utility model provides, its Decompression valves 4 is directly connected with cross axle axis body 1, thereby makes the Bas Discharged of universal joint inside more quick, and the manufacturing of universal joint integral body is also more convenient.
Particularly, described Decompression valves 4 comprises valve body 41, spool 42, Compress Spring 43 and pad 44.The front end of valve body 41 is provided with through hole 411, rear end is provided with counterbore 412, and the diameter of counterbore 412 is greater than the diameter of through hole 411, and counterbore 412 is connected with through hole 411, the axis of counterbore 412 and through hole 411 all with the dead in line of valve body 41.The diameter of spool 42 is less than the diameter of through hole 411, the front end of spool 42 is provided with cartridge cover 421, the diameter of cartridge cover 421 is greater than the diameter of through hole 411, and the rear end of spool 42 is provided with screens 422, the diameter of screens 422 be greater than spool 42 diameter, be less than the diameter of through hole 411.
Further, front end at through hole 411 is provided with through hole chamfering 413, cartridge cover 421 is provided with and the excessive face 423 of the taper being connected, the excessive face 423 of taper matches with the side of through hole chamfering 413, thereby cartridge cover 421 can be fitted tightly with through hole 411 easily, improve the sealing effect of Decompression valves 41.
Particularly, spool 42 is installed on valve body 41 inside, and the rear end of spool 42 is located in counterbore 412 through through hole 411, and Compress Spring 43 is sheathed on the rear end of spool 42, and pad 44 is located between Compress Spring 43 and screens 422.That is to say, pad 44 and Compress Spring 43 are positioned at the counterbore 412 of valve body 41, and pad 44 is connected to screens 422 places of spool 42, and Compress Spring 43 is between pad 44 and counterbore 412 bottom surfaces.
Further, pad 44 center is provided with center hole 441, the bilateral symmetry of center hole 441 be provided with assembling limit 442, the spacing on assembling limit 442 is less than the external diameter of pad 44, is greater than the internal diameter of center hole 441; The external diameter of pad 44 is less than the diameter of through hole 411, the internal diameter of center hole 441 be greater than spool 42 diameter, be less than the diameter of screens 422.In the present embodiment, assembling limit 442 is straight flanges, can certainly be other structures, as arc-shaped side etc.Further, the rear end of spool 42 is provided with blind hole 424, the dead in line of the axis of blind hole 424 and spool 42.This kind of structure met the assembling needs of pad 44 with spool 42, reduced the processing cost of pad 44, also guarantees that pad 44 and screens 422 form interference fit, make Decompression valves 4 overall structures more firm simultaneously.
Embodiment of the present utility model is: Decompression valves 4 is threadedly connected on cross axle axis body 1, and cross axle axis body 1 inside is located in spool 42 rear ends.When tranquility, the spool 42 of Decompression valves 4 fits tightly with through hole 411 in the elastic force effect lower front end cartridge cover 421 of rear end Compress Spring 43, forms sealing configuration, prevents that air from entering universal joint inside by Decompression valves 4.When lubricant oil injects universal joint, the air of cross axle axis body 1 inside increases, and pressure increases.When the air of universal joint inside is enough to promote the further compression Compress Spring 43 of pad 44 to the pressure of spool 42 rear ends, spool 42 outwards moves, make the sealing configuration between cartridge cover 421 and through hole 411 destroyed, air outwards flows out by valve body 41 and the space of spool 42, carry out pressure release, the air of cross axle axis body 1 inside reduces simultaneously, and pressure reduces.When the air pressure of universal joint inside is less than the elastic force of Compress Spring 43, pad 44 turns back to initial position, and band movable valve plug 42 moves inward, and makes cartridge cover 421 and through hole 411 form again sealing configuration, starts pressurize.Along with lubricant oil injects universal joint, Decompression valves 4 continues to carry out the cyclic process of pressure release and pressurize, thereby solved because universal joint internal pressure is excessive, cannot inject the problem of lubricant oil, guaranteed that universal joint inside is full of enough lubricant oil, and then the injection number of times of minimizing lubricant oil, improve the utilization efficiency of lubricant oil, strengthen the flexible performance of universal joint.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace or improvement etc., within all should being included in protection domain of the present utility model.
