Abstract

The utility model relates to a steering knuckle and especially relates to an integral steering knuckle which comprises a pivot pin, a brake arm, an upper arm and a steering arm that are molded into a whole body. The bottom of the pivot pin is a rotating disk portion. The brake arm, the upper arm and the steering arm are disposed on the rotating disk portion of the pivot pin. The beneficial effects of the integral steering knuckle are that through the integral structure, machining and assembling procedures are minimized and press mounting is not needed, therefore, surfaces of parts are not likely to be damaged and defects of stress concentration at matching positions are overcome.

Description

A kind of Integral steering joint
Technical field
The utility model relates to steering swivel, relates in particular to a kind of Integral steering joint.
Background technology
Steering swivel is one of vital parts on steering axle of automobile, can make vehicle steadily travel and sensitive transmission travel direction, 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.
Existing slewing journal structure is as shown in Fig. 1 to 2: steering swivel body 100, pivot pin 200, consist of.Its assembly relation is: by the magnitude of interference, coordinate, pivot pin 200 is pressed in the middle of the centre hole of steering swivel body 100.
There is in the course of the work following problem in this slewing journal structure:
1) processing, assembly process is more;
2), while press-fiting, there is the possibility of damaging pivot pin 200 surfaces;
3) in pivot pin 200 and the cooperation place 201 of steering swivel body 100, there is the concentrated possibility of generation stress.
Summary of the invention
In order to solve the problems of the prior art, the utility model provides a kind of Integral steering joint.
The utility model provides a kind of Integral steering joint, comprises integrated pivot pin, brake control lever, upper arm and spindle arm, and wherein, the bottom of described pivot pin is rotating disk portion, and the end of described brake control lever, upper arm and spindle arm is positioned at the rotating disk portion of described pivot pin.
As further improvement of the utility model, the rotating disk portion of described pivot pin is provided with lightening hole.
As further improvement of the utility model, the axis of described lightening hole and the axis of described pivot pin coincide.
As further improvement of the utility model, described upper arm is provided with lightening grooves.
As further improvement of the utility model, the intersection of the lateral surface of described pivot pin and rotating disk portion is provided with rounding.
As further improvement of the utility model, the radius of described rounding is between 2 to 3 millimeters.
As further improvement of the utility model, described brake control lever has two at least.
As further improvement of the utility model, the rotating disk portion of described pivot pin is provided with Control arm coupling end.
The beneficial effects of the utility model are: by such scheme, adopt integral structure, reduced the operation of processing with assembling, do not exist and press-fit, therefore, also overcome the possibility that piece surface damages, also overcome the concentrated defect of cooperation place stress simultaneously.
Accompanying drawing explanation
Fig. 1 is the perspective view of steering swivel in prior art;

The specific embodiment
Below in conjunction with accompanying drawing explanation and the specific embodiment, the utility model is further illustrated.
Drawing reference numeral in Fig. 3 to Fig. 5 is: rotating disk portion 1; Pivot pin 2; Brake control lever 3; Upper arm 4; Spindle arm 5; Control arm coupling end 6; Lightening hole 7; Lightening grooves 8; Rounding 9.
As shown in Figures 3 to 5, a kind of Integral steering joint, comprise by pivot pin 2, brake control lever 3, upper arm 4 and the spindle arm 5 of forging or casting integrated moulding, wherein, the bottom of described pivot pin 2 is rotating disk portion 1, the end of described brake control lever 3, upper arm 4 and spindle arm 5 is positioned at the rotating disk portion 1 of described pivot pin 2, wherein, pivot pin 2 is for fifth wheel hub unit, described brake control lever 3 is for connecting brake caliper assembly, described upper arm 4 is for connecting front overhang pillar assembly, and described spindle arm 5 is for connecting deflector pull bar, and described Control arm coupling end 6 is for connecting Control arm.
As shown in Figures 3 to 5, the rotating disk portion 1 of described pivot pin 2 is provided with lightening hole 7, can keep, on the basis of intensity, rigidity, reducing weight.
As shown in Figures 3 to 5, the axis of the axis of described lightening hole 7 and described pivot pin 2 coincides.
As shown in Figures 3 to 5, described upper arm 4 is provided with lightening grooves 8, can keep, on the basis of intensity, rigidity, reducing weight.
As shown in Figures 3 to 5, the intersection of the lateral surface of described pivot pin 2 and rotating disk portion 1 is provided with rounding 9, can fall the possibility of stress concentration.
As shown in Figures 3 to 5, the radius of described rounding 9 is between 2 to 3 millimeters.
As shown in Figures 3 to 5, the rotating disk portion 1 of described pivot pin 2 is provided with Control arm coupling end 6.
A kind of Integral steering joint that the utility model provides, adopt the integral structure of pivot pin 2, brake control lever 3, upper arm 4 and spindle arm 5, reduced the operation of processing with assembling, do not exist and press-fit, therefore, also overcome the possibility that piece surface damages, also overcome the concentrated defect of cooperation place stress, by lightening hole 7, lightening grooves 8, reduced total weight respectively simultaneously.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
