Abstract
An automobile steering knuckle is composed of a steering knuckle body (1), an upper swing arm fixing hole (2), a disk brake base fixing hole (3), a hub bearing installing hole (4), hub bolt installing holes (5), a steering pull rod fixing hole (6), a lower swing arm fixing hole (7) and an auxiliary threaded hole (8), wherein the four hub bolt installing holes (5) are of an asymmetrical structure, the angles between the center lines of the four hub bolt installing holes (5) and the X axis and the Y axis formed by the center lines of the four hub bolt installing holes (5) are 22.1 degrees, 68 degrees, 34.5 degrees and 25.3 degrees respectively, the steering pull rod fixing hole (6) is formed in the right end of a steering pull rod connecting arm, the upper portion of the steering pull rod fixing hole (6) is a cylindrical hole, and the lower portion of the steering pull rod fixing hole (6) is a conical through hole with the taper of 1:6. According to automobile steering knuckle, due to an optimized a hub fixing bolt base, the automobile steering knuckle can be applicable to more types of automobiles on the basis that original design is not changed, and universality of parts is improved.
Description
Technical field
The present invention relates to auto parts and components field, particularly relate to a kind of for small-sized 4 wheel driven stub axle.
Background technology
Steering swivel is one of vital parts on steering axle of automobile, and the function of steering swivel is to bear automotive front load, supports and drive front-wheel to make motor turning around stub rotation.Under motoring condition, it is bearing changeable impact load, therefore, requires it to have very high intensity.The major part being connected with spindle has transmission shaft, wheel hub, disc brake support, stable direction pull bar, fixing parts such as swing arm up and down, therefore the fixed form of steering swivel directly affects the safety performance of automobile, the damaged event of the spindle that constantly occurred in recent years running at high speed, therefore improving steering knuckle structure of car, is the only way of improving vehicle safety performance.For this reason, design a kind of high strength, spindle easy for installation, for improving, vehicle operation performance and safety performance are significant.
Summary of the invention
The object of the invention is to solve the technical deficiency of above existence, a kind of novel spindle is provided, under existing steering knuckle structure of car prerequisite, by the dual safety being arranged on steering swivel, steering track rod fixed orifice is set, improve spindle safety performance.
Technical scheme of the present invention is achieved in the following ways: a kind of spindle, by steering swivel main body, top link fixed orifice, disc brake base fixed orifice, hub bearing mounting hole, boss bolt mounting hole, steering track rod fixed orifice, lower swing arm fixed orifice, additional threaded bores forms, in the middle of steering swivel main body, be provided with hub bearing mounting hole, it is top link pipe link that steering swivel main body extends upward elongated portion, top link pipe link top is provided with top link fixed orifice, top link and top link fixed orifice link together, steering swivel main body is turned left and is extended two two ear type structures with hub bearing mounting hole line of centers symmetry, in ear type structure, be respectively arranged with a disc brake base fixed orifice, steering swivel main body is provided with lower swing arm connecting portion to downward-extension, lower swing arm connecting portion below is provided with lower swing arm fixed orifice, steering swivel main body is provided with four boss bolt mounting holes along hub bearing mounting hole surrounding, it is characterized in that: four described boss bolt mounting holes adopt unsymmetric structure, the X that four boss bolt mounting hole line of centerss and boss bolt mounting hole line of centers form, the angle that Y-axis line forms is respectively 22.1 °, 68 °, 34.5 °, 25.3 °.
Described steering swivel main body is extended steering track rod connecting arm to the right, and steering track rod connecting arm right-hand member is provided with steering track rod fixed orifice, and steering track rod fixed orifice is top cylindrical hole, and bottom is the circular cone through hole of tapering 1:6.
Described top link fixed orifice side is also provided with two inconsistent additional threaded bores of the degree of depth, for auxiliary fixedly top link.
The present invention, by the wheel hub bolt of rear end plate seat of optimal design, can not change in original design basis, is applicable to more multi-vehicle-type, has improved the commonality of parts.
