Abstract
The utility model discloses a front knuckle with a ball pin assembly, comprising a knuckle assembly, a ball pin assembly, a slotted nut and a cotter pin. The ball pin assembly comprises a ball pin, wherein the pin rod of the ball pin is provided with a conical surface matched with the knuckle assembly, the head part of the ball pin is provided with a threaded section matched with the slotted nut and a round hole matched with the cotter pin, and the slotted nut is provided with a groove matched with the cotter pin. The utility model has the advantages that the ball pin assembly and the knuckle assembly are matched through a conical surface (more than 75% is fitted) by adopting the slotted nut and the cotter pin, wherein the slotted nut is used for tightening, and the cotter pin is used for locking and limiting, therefore, the traditional structure that the ball pin assembly and the knuckle are matched with each other through a cylindrical hole and a connecting mode using a axial pin bolt for limiting is replaced. The utility model has the advantages of more reasonable design, simple manufacture as well as tight and reliable connection, thereby greatly prolonging the service life of the ball pin assembly.
Description
Technical field
The utility model relates to a kind of knuckle assembly, more specifically says, it relates to a kind of preceding steering swivel dribbling pin assembly.
Background technology
Ball pin assembly is a safety member crucial in the car chassis system, its with steering swivel and swing arm assembly between cooperate, will directly have influence on the reliability and the service life of its use.In case ball pin assembly lost efficacy, consequence is with hardly imaginable.In the prior art, ball pin assembly cooperates by cylindrical hole with steering swivel, and with the spacing connection mode of pivot pin bolt.The subject matter of prior art is: higher to steering swivel and ball end processing request.Want the space length of strict control ball pin mounting hole and pivot pin bolt mounting holes.Undersized, can cause pivot pin bolt dress not advance; Oversize meeting causes the ball pin obviously loosening up and down, even causes the slippage from the steering swivel endoporus of ball pin.In addition, ball lock ring shape grooving is wanted controlling dimension equally, and oversize pivot pin bolt dress does not advance, and it is loosening to cross the bead pin.The steering swivel processing difficulties, operation is many, processes loaded down with trivial details.Requirement of strength to the pivot pin bolt is higher.In implementation process, the pivot pin bolt only is contacting with ball end in theory, and ball pin assembly in use, bears bigger load, so commonly now the pivot pin bolt occurs with structure and bending or fracture defect occur.Now use structure, the gap between ball end and the pivot pin bolt is the major cause that causes the ball pin assembly early failure.Because the gap between ball end and pivot pin bolt, there is the displacement of steering swivel cylindrical hole axis direction in ball pin assembly, in vehicle traveling process, ball pin axis direction loose spacious, can cause the wearing and tearing of ball end club and knuckle bores, along with the increase of abrasion loss, so that ball pin assembly can be occurred, Peril Incident will be occurred from the slippage fault.Ball pin assembly is gone here and there up and down, also can cause the early damage of ball pin dust boot.
Summary of the invention
The purpose of this utility model is to overcome deficiency of the prior art, provides a kind of reasonable in design, make simple, connects fastening reliable, the preceding steering swivel that the improves product service life pin assembly of dribbling.
The purpose of this utility model is achieved through the following technical solutions.Steering swivel dribbling pin assembly before this, comprise knuckle assembly, ball pin assembly, also comprise fluted nut, spring cotter, described ball pin assembly comprises ball end, the pin rod of ball end is provided with the conical surface that cooperates with knuckle assembly, the head of ball end is provided with thread segment that cooperates with fluted nut and the circular port that cooperates with spring cotter, has the groove that cooperates with spring cotter on the fluted nut.
As preferably: described fluted nut is regular hexagon, has circumferentially 6 uniform grooves.
As preferably: the tapering of the pin rod conical surface of described ball end is identical with knuckle assembly taper hole tapering, and ball end conical surface outside diameter is slightly larger than knuckle assembly taper hole outside diameter, and ball end conical surface end diameter is less than knuckle assembly taper hole end diameter.
As preferably: after fluted nut locking, the groove on set circular port of the head of ball end and the fluted nut is positioned at straight line.
As preferably: the set circular port of the head of ball end is two, right-angled crossing mutually, and all axially perpendicular with ball end.
As preferably: the set circular port of the head of ball end is a counter sink.
The beneficial effects of the utility model are: by using fluted nut and spring cotter, and between ball pin assembly and the steering swivel by cone match (75% or more applying), and it is fastening by fluted nut, spring cotter locking is spacing, replaced existing with in the structure, ball pin assembly cooperates by cylindrical hole with steering swivel, and with the spacing connection mode of pivot pin bolt.The utility model design is more reasonable, and making is simple, connection is fastening reliable, and the service life of improving ball pin assembly greatly.
