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, be equipped with a cavity in the bulb, open to the bulb outer wall cavity bottom has the oilhole, the cavity top has hung soft spring, is fixed with the balancing weight at the lower extreme of soft spring, still be fixed with the one deck filter screen in the cavity, the filter screen is in the below of balancing weight, places one and adsorb the sponge that has lubricating oil on the filter screen. The utility model discloses a self -lubricating car pull rod joint mechanism, the problem of the unable self -lubricating of bulb among the present automobile pull rod joint mechanism has been solved to the structure that adopts the balancing weight extrusion to have the sponge of lubricating oil.
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, a cavity is provided with in described bulb, described cavity bottom has oilhole to bulb outer wall, described cavity top is hung with soft spring, balancing weight is fixed with in the lower end of soft spring, one deck filter screen is also fixed with in described cavity, described filter screen is in the below of balancing weight, filter screen is placed the sponge that is adsorbed with lubricant oil, when self-lubricating automotive rod head mechanism is static, soft spring is in normal stretch state, balancing weight does not contact with sponge, when self-lubricating automotive rod head mechanism uses, soft spring is in improper extended state, balancing weight extruding sponge.
Described cavity is cylindrical body.
Described bulb surface is provided with oil groove, and described oil groove is connected with oilhole.
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, adopt balancing weight extruding with the structure of the sponge of lubricant oil, when vehicle traveling is jolted, the kinetic transformation of spring is the potential energy of balancing weight, balancing weight extruding sponge, lubricant oil in sponge is extruded, flow between filter screen and cavity bottom subsequently, finally flow out from oilhole, to bulb, there is lubrication.
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, a cavity 6 is provided with in described bulb 2, oilhole 7 is had to bulb 2 outer wall bottom described cavity 6, described cavity 6 top is hung with soft spring 8, balancing weight 9 is fixed with in the lower end of soft spring 8, one deck filter screen 10 is also fixed with in described cavity 6, described filter screen 10 is in the below of balancing weight 9, filter screen 10 is placed the sponge 11 that is adsorbed with lubricant oil, when self-lubricating automotive rod head mechanism is static, soft spring 8 is in normal stretch state, balancing weight 9 does not contact with sponge 11, when self-lubricating automotive rod head mechanism uses, soft spring 8 is in improper extended state, and balancing weight 9 extrudes sponge 11.
Described cavity 6 is in cylindrical body.
Described bulb 2 surface is provided with oil groove 12, and described oil groove 12 is connected with oilhole 7.
Working principle of the present utility model is as follows:
Self-lubricating automotive rod head mechanism of the present utility model, bulb 2 and ball stud 1 are designed to separable structure, like this, the upper end of soft spring 8 is weldingly fixed on the lower end surface of ball stud 1, balancing weight 9 is fixed on the lower end of soft spring 8, place in the cavity 6 of bulb 2 and fix filter screen 10, filter screen 10 is placed sponge 11, on sponge 11 fall lubricant oil, treat have lubricant oil to overflow in oilhole 7, namely show that sponge 11 is filled lubricant oil, finally, ball stud 1 and bulb 2 are fixed, soft spring 8 is in cavity 6 with balancing weight 9.Self-lubricating automotive rod head mechanism of the present utility model, be installed on compact car, when the vehicle is still, the elastic potential energy of soft spring 8 determined by the weight of balancing weight 9 completely, balancing weight 9 now still has certain distance with sponge 8, sponge 8 is in the state to lubricant oil normal sorption, when the vehicle is running, due to jolting of vehicle, the elastic potential energy of soft spring 8 increases, balancing weight 9 meeting extruding sponge 11 often, because sponge 11 is filled lubricant oil, like this, the sponge 11 be squeezed, lubricant oil wherein is just extruded and flow to filter screen less than 10, finally flow out through oilhole 7, lubricate whole bulb 2.
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.
