Description
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 for spacing multi-connecting-rod linear guiding formula independent suspension.
Background technology
Manned vehicle in present market is suspension many link-types independent suspensions that adopt of intermediate car especially more, the steering swivel be used in conjunction with is one of parts crucial in suspension frame structure, and its Main Function is to connect each pilot bar side chain of multi-connecting-rod separated suspension, shock absorber, brake caliper and hub bearing.
Although the conventional independent suspensions such as Multi-link suspension can both meet the suspension design requirement on function at present, when wheel bounce, wheel alignment parameter all can change.In actual applications, the variation of any positional parameter of wheel all can have a negative impact to vehicle handling stability or other aspect performances.Descend such as, the variation of wheelspan can cause automobile straight line driveability, also cause rolling resistance to increase and on the impact of steering swivel system simultaneously; The variation of camber angle can cause the inordinate wear of tire etc.In the time of how can guaranteeing wheel bounce, can not change be a Focal point and difficult point in the independent suspension structure innovative design to the positional parameter of wheel.For this problem, I take charge of invented a kind of can be for the spacing multi-connecting-rod linear guiding formula suspension of Motor Vehicle Independent Suspension System, referring to [1. providing holt, Zhao Jingshan, Zhang Jie, Liu Xiang etc. with many link linear guide independent suspensions of 3-RRR flexible compensation mechanism: China, 201120274238.5[P] .2011-08-01.], this suspension fork mechanism can make the camber angle of wheel, Kingpin inclination angle and casterangle, the left and right wheels distance, toeing-in (posterior cord) and wheel base substantially remain unchanged in wheel bob process, thereby improve the road-holding property of automobile, riding comfort and the traveling comfort of taking, and can effectively reduce the wearing and tearing of tire.Simultaneously, under the prerequisite with stronger exploitativeness, can guarantee that this suspension fork mechanism has large respectively to rigidity, reduce as far as possible the stand under load distortion.
Steering swivel commonly used can not be complementary with novel many link linears guiding type suspension at present, 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 of suspension.
Summary of the invention
The object of the invention is to overcome the deficiency of above-mentioned existence, and a kind of steering swivel 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 complete by following technical solution, it comprises steering swivel main body and hub anchor shaft, offers four journal stirrups on the steering swivel main body, is respectively upside the first journal stirrup that forms the upside journal stirrup, upside the second journal stirrup; Form downside first journal stirrup of downside journal stirrup, downside the second journal stirrup, also be provided with brake clamp bearing and absorber seat on 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 the first journal stirrup, upside the second journal stirrup, downside the first journal stirrup, downside the second journal stirrup is 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 the first journal stirrup and upside the second journal stirrup, downside the first journal stirrup and downside the second journal stirrup, all about the vertical plane symmetry of described 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 and; 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 described steering swivel main body, be equipped with hollow structure.
The present invention compared with prior art, have the following advantages and the high-lighting effect: the automobile of applying this steering swivel and linear guiding formula suspension fork mechanism, can realize that wheel alignment parameter can remain constant in wheel bob process, thereby effectively reduce the wearing and tearing of tire, and can effectively improve road-holding property, the riding comfort of automobile and the traveling comfort of taking; In addition, in suspension pilot bar side chain on this steering swivel journal stirrup, the diameter of outside connecting bore is not identical, 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 by adjusting nut the function of adjusting revolute pair joint gap and pretension; The middle part of upside journal stirrup, downside journal stirrup and absorber seat in the steering swivel main body, can arrange 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 has the advantages such as the strong and equipment adjustment of designability facilitates.
