Description

A kind of steering swivel that is used for spacing multi-connecting-rod linear guiding formula suspension
Technical field
The present invention relates to the steering swivel of auto parts and components, be particularly related to a kind of connection bearing set that is used for spacing multi-connecting-rod linear guiding formula independent suspension.
Background technology
Manned vehicle in the present market is suspension many link-types independent suspensions that adopt of intermediate car especially more; The steering swivel that is used is one of parts crucial in the suspension frame structure, and it mainly acts on is to connect each pilot bar side chain of multi-connecting-rod separated suspension, shock absorber, brake caliper and hub bearing.
Though conventional at present independent suspensions such as many link-types suspension can both satisfy the suspension design requirement on function, when wheel bounce, wheel alignment parameter all can change.In practical application, the variation of any positional parameter of wheel all can have a negative impact to vehicle handling stability or other aspect performances.Such as, the variation of wheelspan can cause automobile straight-line travelling ability drop, also causes rolling resistance to increase simultaneously and to the influence of steering swivel system; The variation of camber angle can cause the inordinate wear of tire etc.Can not change be emphasis and the difficult point in the independent suspension structure innovative design to the positional parameter of wheel in the time of how can guaranteeing wheel bounce.To this problem; I take charge of and have invented a kind of spacing multi-connecting-rod linear guiding formula suspension that can be used for Motor Vehicle Independent Suspension System, referring to [1. supporting holt, Zhao Jingshan; Zhang Jie; Liu Xiang etc. have many connecting rods linear guiding independent suspension of 3-RRR flexible compensation mechanism: China, 201120274238.5 [P] .2011-08-01.], this suspension fork mechanism can make camber angle, Kingpin inclination angle and casterangle, left and right wheels distance, toeing-in (posterior cord) and the wheel base of wheel in wheel bob process, remain unchanged basically; Thereby improve road-holding property, the riding comfort of automobile and the traveling comfort of taking, and can effectively reduce Tyte Wear.Simultaneously, under the prerequisite with stronger exploitativeness, it is big respectively to rigidity to guarantee that this suspension fork mechanism has, and reduces the stand under load distortion as far as possible.
Steering swivel commonly used at present can not be complementary with later-model many connecting rods linear guiding formula suspension, can't realize that each side chain of suspension fork mechanism is connected with the smooth of hub, therefore needs design to be applicable to the knuckle mechanism of this kind suspension.
Summary of the invention
The objective of the invention is to overcome the deficiency of above-mentioned existence, and a kind of steering swivel that is used for spacing multi-connecting-rod linear guiding formula suspension is provided, can connect each side chain of linear guiding formula suspension, shock absorber and brake caliper and hub bearing.
The objective of the invention is to accomplish through following technical scheme, it comprises steering swivel main body and hub anchor shaft, offer four journal stirrups on the steering swivel main body, is respectively upside first journal stirrup that constitutes the upside journal stirrup, upside second journal stirrup; Constitute downside first journal stirrup of downside journal stirrup, downside second journal stirrup also is provided with brake clamp bearing and absorber seat on the described steering swivel main body; Be provided with the brake caliper connecting bore in this brake clamp bearing, be provided with the jounce bumper connecting bore in this absorber seat.
As preferably, described upside first journal stirrup, upside second journal stirrup, downside first journal stirrup, downside second journal stirrup are equipped with suspension pilot bar side chain connecting bore; The intersection on determined two the vertical planes of suspension side chain connecting bore axis of upside journal stirrup, with the intersection on determined two the vertical planes of suspension side chain connecting bore axis of downside journal stirrup, both overlap or are parallel.
As preferably, described upside first journal stirrup and upside second journal stirrup, downside first journal stirrup and downside second journal stirrup are all about the vertical plane symmetry of said intersection and steering stub axle line of centers.
As preferably, described suspension pilot bar side chain connecting bore is divided into inboard suspension pilot bar side chain connecting bore and outside suspension pilot bar side chain connecting bore, its axis heavy with; And the diameter of inboard suspension pilot bar side chain connecting bore is less than the diameter of outside suspension pilot bar side chain connecting bore.
As preferably, under the prerequisite that reaches static strength and life requirements, to alleviate the weight of this steering swivel main body, the middle part of upside journal stirrup, downside journal stirrup and absorber seat in the described steering swivel main body is equipped with hollow structure.
The present invention compared with prior art; Have the following advantages and the high-lighting effect: the automobile of using this steering swivel and linear guiding formula suspension fork mechanism; It is constant to realize that wheel alignment parameter can remain in wheel bob process; Thereby effectively reduce Tyte Wear, and can improve road-holding property, the riding comfort of automobile and the traveling comfort of taking effectively; In addition; The diameter of outside connecting bore is inequality in the suspension pilot bar side chain on this steering swivel journal stirrup; Therefore can on the pin that connects suspension pilot bar side chain and steering swivel journal stirrup, overlap upper bush by an end, thereby reach the function of adjustment revolute pair joint gap and pretension through the adjustment nut; The middle part of upside journal stirrup, downside journal stirrup and absorber seat in the steering swivel main body can be provided with hollow structure, under the prerequisite that reaches static strength and life requirements, can alleviate the weight of steering swivel; That this steering swivel has is simple in structure, be easy to processing and weight-saving characteristics, also have designability strong with advantages such as assembling is easy to adjust.
