Description

A kind of lightweight steering swivel
Technical field
The present invention relates to a kind of steering swivel applied on automobile, relate in particular to a kind of lightweight steering swivel being suitable for racing car.
Background technology
Steering swivel is one of vital parts on steering axle of automobile, and vehicle steadily can be made to travel and sensitive transmission travel direction, and the function of steering swivel bears automotive front load, support and drives front-wheel to make motor turning around stub rotation.Under motoring condition, it subjects changeable impact load, is one of key components and parts on automobile, has very high requirement of strength.Therefore, people have carried out large quantifier elimination to steering swivel, just define society get on the car in panoramic slewing journal structure, constantly promote the performance of automobile.Under normal circumstances, steering swivel can adopt the mode of quenching to be optimized it, but surface hardening process is not easy to operate, the performance of laser quenching hardened layer can not effectively be ensured, the bad control of steering swivel case depth, case depth increases, strength at repeated alternation increases, but when hardened-depth is spent dark, top layer is compression effort, and thus case depth is excessive, strength at repeated alternation declines on the contrary, and workpiece fragility is increased.Case depth shallow then out of reach effect, this just creates tremendous influence to the performance of steering swivel, especially more huge on the impact of automotive wheels passive axostylus axostyle.
In order to solve the problem, Chinese patent literature CN103057590A discloses a kind of high-strength automobile steering knuckle, comprises terminal pad, described terminal pad side is provided with axostylus axostyle, opposite side is provided with two fork ears, and described fork ear is respectively equipped with pin-and-hole, and described axle surface is provided with carburizing strengthening layer.Namely the high strength steering swivel described in above-mentioned patent documentation, by arranging carburizing strengthening layer at the axle surface of steering swivel, makes steering swivel become hardness high, and wear resisting property is good, and strength at repeated alternation is high, the high strength steering swivel that anti-shock loading is large.
But the high strength steering swivel described in above-mentioned patent documentation has the following disadvantages: this steering swivel adopts solid manufacture to form, weight is surprising, intensity is superfluous, shorter and smaller and the machining process more complicated of size, be only applicable to the mass production method that automotive field is such, and racing car field can not be met for weight-saving requirement, so-called lightweight is exactly under the guarantee intensity of automobile and the prerequisite of safety performance, reduce the curb mass of automobile as much as possible, lightweight, can bring better handling, the power that driving engine exports can produce higher acceleration/accel, vehicle is light, during starting, acceleration capability is better, stopping distance during brake is shorter.
Summary of the invention
For this reason, technical matters to be solved by this invention is that in prior art, steering swivel is solid manufacture, and weight is large, and processing technology is complicated, and then provides a kind of quality little, lightweight, is easy to processing, can meets the lightweight steering swivel of racing car field lightweight requirements.
For solving the problems of the technologies described above, a kind of lightweight steering swivel of the present invention, it comprises the steering swivel skeleton being applicable to being connected with suspension system, be arranged on the wheel shaft on described steering swivel skeleton and braking ear, described steering swivel skeleton forming is panel, the circumferential side wall of described panel is solid wall, the circumferential side wall of described panel around centre portion be netted hollow out, described wheel shaft is arranged perpendicular to described panel.
Described braking ear is located on the sidewall on the thickness direction of described steering swivel skeleton, and arranges near described wheel shaft.
Described braking ear and described steering swivel frame welding are fixed.
One end away from described wheel shaft of described steering swivel skeleton, and the middle part of described steering swivel skeleton is equipped with the yoke connecting bore penetrating described plate thickness, the sidewall of each described yoke connecting bore forms the bolt hole penetrating described yoke connecting bore sidewall, by bolt, the yoke in the described suspension system inserted in described yoke connecting bore is connected with described steering swivel skeleton.
Described yoke connecting bore forms two, is separately positioned on described panel one end away from described wheel shaft, and the middle part of described panel.
Described panel is fixedly connected with hole away from one end of described wheel shaft is also provided with one, the described sidewall being fixedly connected with hole forms the bolt hole being fixedly connected with hole sidewall described in penetrating, by bolt, the connecting rod in the described suspension system be fixedly connected with described in insertion in hole is connected with described steering swivel skeleton.
The bolt borehole jack had for strengthening resistance to abrasion is all overlapped in described bolt hole.
Described steering swivel skeleton forming is inverted trapezoidal panel, and described wheel shaft is arranged on the small end end of described inverted trapezoidal panel.
Described steering swivel skeleton and described wheel shaft are formed in one.
Described inverted trapezoidal panel is divided into upper and lower two parts by the crossbeam of entity, and described netted hollow out is molded on described upper and lower two parts, and described netted hollow out is the netted hollow out of honeycomb, and the described yoke connecting bore of described middle panel is molded on described crossbeam.
Technique scheme of the present invention has the following advantages compared to existing technology:
(1) in the present invention, described steering swivel skeleton forming is panel, and the circumferential side wall of described panel is solid wall, the circumferential side wall of described panel around centre portion be netted hollow out, described wheel shaft is arranged perpendicular to described panel, namely described steering swivel skeleton is no longer solid manufacture, and makes the middle panel for netted hollow out, while the intensity ensureing this steering swivel, there is quality little, lightweight, be easy to the feature of processing, the weight-saving requirement of racing car field can be met.
(2) in the present invention, described steering swivel skeleton forming is inverted trapezoidal panel, the lower end of described steering swivel skeleton is vertically provided with described wheel shaft, the large end of described steering swivel skeleton and midway location are provided with described yoke connecting bore, thus this steering swivel can be connected with suspension system smoothly, the requirement that installing wheel is wanted in this steering swivel bottom can be met again, wheel is constantly rotated around described wheel shaft in the process of moving.
