Description

Universal joint out star wheel inner chamber concentricity thimble
Technical field
The utility model relates to a kind of universal joint out star wheel inner chamber concentricity thimble, belongs to Car Drive Shaft constant velocity cardan joint product manufacturing technical field.
Background technology
The important node that universal joint out star wheel is constant velocity cardan joint carry-over moment and turns to, its fatigue resistance and service life, is related to stability and the security performance of running car; As everyone knows, the connecting axle portion that universal joint out star wheel mainly comprises clutch can portion and is coaxially connected with clutch can portion, in the preprocessing operation that described connecting axle end surface working axiality positioning process hole is universal joint out star wheel, out star wheel inner chamber concentricity thimble in the process in axiality positioning process hole, can be used to improve the axiality of out star wheel location.Tradition concentricity thimble structure many employings pneumatic actuation and complex structure, requires also high, so maintenance cost is high to the air-tightness of assembly.
Summary of the invention
The utility model for the deficiency that prior art exists, provides a kind of universal joint out star wheel inner chamber concentricity thimble just, to realize object that is simple to operate, that hold great efforts, reduce operating cost and maintenance cost.
For solving the problem, technical solution adopted in the utility model is as follows:
A kind of universal joint out star wheel inner chamber concentricity thimble, comprising: some through holes be disposed radially, is provided with a tensioner pearl and a piston in each described through hole; Also comprise central shaft hole, described central shaft hole is blind hole, and arranges along thimble central shaft; Described through hole through thimble outer surface and described central shaft hole, circular array mode is distributed in thimble radial section; Described tensioner pearl comprises link and holding end, and described piston is slidably disposed in described through hole, and described piston is fixedly connected with by the link of connecting rod with described tensioner pearl; Also comprise fluid power system, described fluid power system comprises header, fuel tank, described header one end connects described central shaft hole, the other end connects selector switch valve, is connected between described selector switch valve and described fuel tank by the first oil pump in parallel, the second oil pump.
As the improvement of technique scheme, described through-hole wall is also fixedly installed restraining position ring block.
As the improvement of technique scheme, the end that described through hole is positioned at described central shaft hole is connected with oil connection, described fluid power system also comprises oil distributing pipe, flow divider-combiner, described oil distributing pipe is connected with described oil connection, and described flow divider-combiner is connected between described oil distributing pipe and described header.
Compared with prior art, implementation result of the present utility model is as follows for the utility model:
Universal joint out star wheel inner chamber concentricity thimble described in the utility model, while guaranteeing the holding distance and hold dynamics of tensioner pearl, structure is simple, simple to operate and operation and maintenance cost is low.
Accompanying drawing explanation
Fig. 1 is tensioner pearl described in the utility model cross section structure schematic diagram perpendicular to axial direction;
Fig. 2 is the structural representation of hydraulic system described in the utility model.
Detailed description of the invention
Below in conjunction with specific embodiments content of the present utility model is described.
As depicted in figs. 1 and 2, be universal joint out star wheel inner chamber concentricity thimble structure schematic diagram described in the utility model.Out star wheel inner chamber concentricity thimble described in the utility model, comprises some through holes 1 be disposed radially, and is provided with a tensioner pearl 2 and a piston 3 in each described through hole 1; Also comprise central shaft hole 4, described central shaft hole 4 is blind hole, and arranges along thimble central shaft; Described through hole 1 through thimble outer surface and described central shaft hole 4, circular array mode is distributed in thimble radial section; Described tensioner pearl 2 comprises link 21 and holding end 22, and described piston 3 is slidably disposed in described through hole 1, and described piston 3 is fixedly connected with by the link 21 of connecting rod with described tensioner pearl 2; Also comprise fluid power system, described fluid power system comprises header 5, fuel tank 6, described header 5 one end connects described central shaft hole 4, the other end connects selector switch valve 7, is connected between described selector switch valve 7 and described fuel tank 6 by the first oil pump 8, second oil pump 9 in parallel.
Particularly, described first oil pump 8 is set as multiple flow pump, the second oil pump 9 be set as reflux oil pump, described tensioner pearl 2 hold action by following process implementation: described multiple flow pump runs, described selector switch valve 7 is communicated with described multiple flow pump and described header 5, liquid in described fuel tank 6 is scattered in each described through hole 1 after entering described central shaft hole 4 by described header 5 again, the expansion of liquid volume promotes the movement outside of described piston 3 to described through hole 1, and then realizes described tensioner pearl 2 and outwards hold.Hold after operation completes when described tensioner pearl 2, described tensioner pearl 2 is needed to be reset in described through hole 1, the homing action of described tensioner pearl 2 is by following process implementation: described withdrawing oil pump operation, described selector switch valve 7 is communicated with described backflow oil pump and described header 5, in described through hole 1, liquid is by described header 5, described withdrawing oil pump reflux extremely described fuel tank 6, in described through hole 1 liquid volume reduce the medial motion making described piston 3 to described through hole 1, and then realize described tensioner pearl 2 and inwardly reset.
Further, described through hole 1 inwall is also fixedly installed restraining position ring block 10.Described spacing ring 10 can arrange one group, also can arrange many groups, and setting position is also comparatively flexible, and as described in as near in through hole 1 as described in being arranged at, the position of the holding end 22 of tensioner pearl 2, also can be arranged at two terminals of sliding trace in described piston 3 course of work.This improves the offside operation of piston 3 or tensioner pearl 2 when being to be avoided oil pump or pipeline road to occur abnormal conditions.
Further, the end that described through hole 1 is positioned at described central shaft hole 4 is connected with oil connection 11, described fluid power system also comprises oil distributing pipe 12, flow divider-combiner 13, described oil distributing pipe 12 is connected with described oil connection 11, and described flow divider-combiner 13 is connected between described oil distributing pipe 12 and described header 5.This improves mainly direct for former header 5 structure connecting central shaft hole 4 to be changed to and arrange flow divider-combiner 13 between header 5 and each through hole 1, this object improved is that equivalent is shunted, and whole thimble need not be changed during oil path failure, only need change corresponding oil pipe or oil connection 11, reduce maintenance cost.
Above content is in conjunction with specific embodiments to the detailed description that the utility model is done, and can not assert that the utility model is specifically implemented to be only limitted to these explanations; For the utility model person of ordinary skill in the field, without departing from the concept of the premise utility, some simple deduction or replace can also be made, all should be considered as the scope belonging to the utility model protection.
