Description
Technical field
This utility model relates to a kind of dust cover connector assembly.
Background technology
At present, conventional Motor vehicle steering link connector assembly is mainly made up of ball pin, joint, upper ball base, lower ball base, spring base, spring, oil nozzle, cover plate etc., or lower ball base and spring base is united two into one, and cover plate can also be changed to plug screw.Not only structure is complicated for it, but also after having the disadvantage that the assembling of (1) connector assembly, when ball pin produces suitable moment, working depth and pressure difference highly due to spring, and the mismachining tolerance of joint and produce bigger axial gap, thus when in vehicle traveling process, when connector assembly is with suspension bob, ball pin is easily generated axial float, so that the pendulum shake of driver's feel, direction is wayward, also accelerates the abrasion between ball pin and ball seat, between upper ball base and joint housing simultaneously；(2) on, lower ball base and ball pin all adopt rigid material to make, there is mismachining tolerance and heat treatment deformation, thus when upper, lower ball base coordinates with ball pin, and upper ball base is when coordinating with joint, there is fit clearance, and their contact surface is uneven, in line contact, during use, abrasion differ, abrasion is accelerated, axially and radially gap between ball pin and ball seat increases, thus causing whole connector assembly hydraulic performance decline, service life is substantially reduced, even occur that in use procedure, ball pin and upper ball base do not have relative motion, but upper ball base produces relative motion with joint, the abrasion of aggravation joint is thus causing the serious consequence that ball pin is deviate from from joint significantly.
For the problems referred to above, the patent document that publication number is CN2733075 discloses a kind of Motor vehicle steering link connector assembly, its technical scheme is: include dust cover, ball pin, joint and cover plate, the ball seat that described ball pin lower end is made equipped with elastomeric material, ball pin and joint, ball seat closely cooperate, and ball seat and cover plate compact siro spinning technology.
But, in the technical scheme of above-mentioned patent document.Owing to dust cover upper end is connected in ball pin by collar, after a protracted use, collar easily produces to loosen thus affecting dust-proof effect.And riveting is passed through on joint in dust cover lower end, easily protrude after long-time use and drop.
Utility model content
This utility model is intended to provide a kind of dust cover connector assembly, so that dust cover and ball pin and joint compact siro spinning technology, occurs without the phenomenon loosening and dropping.
Dust cover connector assembly in this programme, base case is: include joint, ball pin, ball pin is by spheroid, changeover portion and connecting portion form successively, the cavity volume adapted with spheroid is offered in joint, the ball seat coordinated with spheroid it is provided with at the bottom of the chamber of cavity volume, changeover portion and described connecting portion extend radially outwardly along described spheroid, the cover plate that ball seat is spacing it is provided with outside ball seat, also include dust cover, dust cover upper end is provided with vulcanite ring, vulcanite ring periphery is connected with sulfuration collar, dust cover upper end is fixed on the connecting portion of ball pin by vulcanite ring and sulfuration collar, joint outer rim is provided with the groove of annular, dust cover lower end is provided with the projection of the annular with fit depressions, collar it is provided with in projection.
Operation principle and beneficial effect: unlike the prior art, it is provided with vulcanite ring in dust cover upper end, sulfuration collar it is arranged with outside vulcanite ring, it is then passed through sulfuration, make firmer being difficult to of sulfuration collar deform, and sulfuration after cure rubber ring and sulfuration collar link into an integrated entity, sulfuration collar without departing from, make the fixing more persistently reliable of dust cover upper end, it is to avoid dropping occurs and loosens.In dust cover lower end, by setting the groove of annular in joint outer rim, dust cover lower end is provided with the projection with fit depressions, sets collar in projection, makes projection be connected in groove, and is fastened by collar so that fixing of lower end is also relatively reliable.
Scheme 2, as the improvement to base case, cover plate has the structure adapted with ball pin.Advantage is, it is simple to ball pin rotates in cavity volume.
Scheme 3, as the improvement to base case, protruding by dust cover portion integral molding.Advantage is, one-body molded firm and be easy to manufacture.
