Abstract
The utility model discloses a self -lubricating car pull rod joint mechanism, including bulb round pin and overcoat in the joint of bulb round pin afterbody, bulb round pin afterbody is the bulb, and the bulb is covered with and connects the assorted dust cover outside the bulb round pin middle part position in locating the bulb seat, the outer chrome -faced of bulb plates the one deck copper alloy at bulb seat internal surface, sets up a plurality of blind holes on the internal surface of the surface of the bulb of mutually supporting and bulb seat, and the distribution that misplaces each other of a plurality of blind holes, the blind hole is embedded to have solid lubricant, the blind hole diameter is 2mm~3mm, and the degree of depth is 4mm~5mm. The utility model discloses a self -lubricating car pull rod joint mechanism has excellent wearability, self -lubricating nature, simultaneously, still has higher bearing capacity.
Description
Technical field
The utility model relates to a kind of self-lubricating automotive rod head mechanism.
Background technique
Automobile pull rod joint mechanism is the vitals in auto steerer, if there are wearing and tearing in the bulb in automobile pull rod joint mechanism, cause occurring gap between bulb and ball cup, in steering procedure, then very easily can occur that steering wheel loosens or the situation of shakiness, affect traffic safety, and in order to solve the above problem, driving personnel always can carry out lubrication work in automobile pull rod joint mechanism frequently, but because bulb is installed in inside ball cup, and ball cup is positioned at joint, therefore cause bulb present position very special, be difficult to directly lubricate it, need to carry out lubrication work to bulb by after the dismounting of automobile pull rod joint mechanism major part, seem and extremely bother, and general lubrication work all needs the carrying out of staff's not timing, if staff forgets sometimes, under the adjustment not having oiling agent, once automobile pull rod joint mechanism runs, bulb then can carry out rubbing with ball cup thus cause wearing and tearing in rotation process, finally make to occur gap between bulb and ball cup.
Summary of the invention
The utility model will solve the bulb of existing automobile pull rod joint mechanism cannot the technical problem of selflubricating.
The technical scheme in the invention for solving the above technical problem is:
Self-lubricating automotive rod head mechanism, comprise ball stud and be coated at the joint of ball stud afterbody, ball stud afterbody is bulb, bulb is located in ball cup, ball stud medium position is covered with the dust-proof cover matched with joint, the outer surface chromium plating of described bulb, one deck Cuprum alloy is plated at ball cup internal surface, the outer surface of the bulb cooperatively interacted and the internal surface of ball cup arrange multiple blind hole, and multiple blind hole mutual dislocation distribution, described blind hole is embedded with solid lubricant, and described blind hole diameter is 2mm ~ 3mm, and the degree of depth is 4mm ~ 5mm.
Span between described blind hole and blind hole is 6mm ~ 8mm.
The cross section of described blind hole is irregular polygon.
The technique effect that the utility model can reach is:
Compared with prior art, self-lubricating automotive rod head mechanism of the present utility model, in the outer surface chromium plating of bulb, one deck Cuprum alloy is plated at ball cup internal surface, and multiple blind hole be dislocatedly distributed is set, in blind hole, inlaid solid lubrication oil, has excellent wear resistance, self lubricity, meanwhile, also there is higher bearing capacity.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model self-lubricating automotive rod head mechanism.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Refer to Fig. 1, the utility model provides a kind of self-lubricating automotive rod head mechanism, comprise ball stud 1 and be coated at the joint 4 of ball stud 1 afterbody, ball stud 1 afterbody is bulb 2, bulb 2 is located in ball cup 3, ball stud 1 medium position is covered with the dust-proof cover 5 matched with joint 4, the outer surface chromium plating 6 of described bulb 2, one deck Cuprum alloy 7 is plated at ball cup 3 internal surface, the outer surface of the bulb 2 cooperatively interacted and the internal surface of ball cup 3 arrange multiple blind hole 8, and multiple blind hole 8 mutual dislocation distribution, described blind hole 8 is embedded with solid lubricant, described blind hole 8 diameter is 2mm ~ 3mm, the degree of depth is 4mm ~ 5mm.
Span between described blind hole 8 and blind hole 8 is 6mm ~ 8mm.
The cross section of described blind hole 8 is irregular polygon.
Above the self-lubricating automotive rod head mechanism that the utility model embodiment provides is described in detail, apply specific case herein to set forth principle of the present utility model and mode of execution, the explanation of above embodiment is just for helping to understand the technological scheme that the utility model discloses; Meanwhile, for one of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.
