Abstract
A front axle steering knuckle arm is composed of a steering knuckle arm body. The steering knuckle arm body is composed of a left section body and a right section body, the axis of the left section body and the axis of the right section body are arranged not to be in the same axis position, and the axis of the left section body and the axis of the right section body are arranged to form a 16-degree included angle. When a horizontal pull rod is arranged in front of a front axle, the front axle steering knuckle arm forms a reasonable steering trapezoid so that a left front wheel and a right front wheel of a vehicle obtain reasonable deflection angle matching when a vehicle turns. Wheels are made to conduct pure rolling on different circumferences around the same instant steering center to avoid or reduce side slipping of tires, therefore, the service life of the tires is prolonged, and stability when the vehicle turns is improved.
Description
Technical field
The utility model belongs to the motor turning technical field, and what be specifically related to is a kind of front axle steering knuckle arm.
Background technology
Vehicle bridge is one of vitals of car chassis, and vehicle bridge links to each other with vehicle frame or vehicle body by suspension system, and wheel is installed at two ends, transmits the application force of all directions between vehicle frame or vehicle body and the wheel; Generally, vehicle bridge has not only been born the vertical load from frame or vehicle body, and in vehicle traveling process, also bears the impact load that landing ground comes by the wheel transmission, and namely the quality of vehicle bridge performance directly has influence on the safety performance of car load.
Steeraxle, usually be referred to as propons, generally comprise front-axle beam steering swivel, track arm and wheel hub etc., steeraxle is to utilize steering swivel to make wheel deflection certain angle, to reach the purpose of automobile turning, steeraxle also bears former thereby the longitudinal force of generation and the side force that automobile turning causes such as automobile brake and acceleration except bearing vertical load, and the effect of the moment that causes of these power, stressed complexity; Whole bar of present existing track arm all be assembled portion with the band tapering on same axis, this makes that intermediate rod, track arm and front axle can't form when intermediate rod is contained in the place ahead of propons and turns to ladder type, makes tire occur premature wear easily.
Summary of the invention
The purpose of this utility model is at the deficiencies in the prior art, and a kind of reasonable in design is provided, and whole bar of track arm and the assembled portion of this bar band tapering are not in same axis front axle steering knuckle arm.
The utility model is achieved through the following technical solutions: the front axle steering knuckle arm, formed by the track arm body, this track arm body is made up of left and right two segment bodies, and left segment body and right segment body axis be not in same axial location setting, and is 16 degree angle settings.
Described right segment body is the stepped shaft shape.
The coupling end of described left segment body and right segment body is made as taper shaft.
The beneficial effects of the utility model embody and are: prior art is compared, and the utility model forms when intermediate rod is contained in the place ahead of propons and reasonably turns to ladder type; Left and right front-wheel obtains rational angle of inclination coupling when making motor turning; Make wheel make pure rolling around same instantaneous center of turn at different circumference, avoiding or to reduce tire and break away, thereby prolong service life of tire, improve the stability of Ackermann steer angle.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in detail.
Fig. 1 is the utility model structural representation.
Following is the concrete title of each sign among the figure: 1 left segment body, 2 right segment bodies.
The specific embodiment
As shown in Figure 1, the front axle steering knuckle arm is made up of the track arm body, and this track arm body is made up of left and right two segment bodies (1,2), and left segment body 1 is not in same axial location setting with right segment body 2 axis, and is 16 degree angle settings.
Left side segment body 1 is made as taper shaft with the coupling end of right segment body 2.
The utility model track arm is symmetrical set, and couples together by intermediate rod between this track arm, and intermediate rod, track arm and front axle form and turn to ladder type when intermediate rod is contained in the place ahead of propons, have significantly reduced the premature wear of tire.
Claims (3)
1. the front axle steering knuckle arm is made up of the track arm body, it is characterized in that: the track arm body is made up of left and right two segment bodies, and left segment body and right segment body axis be not in same axial location setting, and is 16 degree angle settings.
2. front axle steering knuckle arm according to claim 1, it is characterized in that: right segment body is the stepped shaft shape.
