Background
A Steering Knuckle (Steering Knuckle), also known as a "claw", is one of important parts in an automobile Steering axle, and can enable an automobile to stably run and sensitively transmit the running direction. The steering knuckle is used for transmitting and bearing the front load of the automobile, supporting and driving the front wheel to rotate around the main pin so as to steer the automobile. In the driving state of the vehicle, it is subjected to a variable impact load, and therefore, it is required to have a high strength. The knuckle is a hinge for steering the wheel, and is generally fork-shaped. The upper fork and the lower fork are provided with two coaxial holes for mounting the main pin, and the steering knuckle journal is used for mounting a wheel. Two ears of a pin hole on the steering knuckle are connected with the fist-shaped parts at two ends of the front shaft through the main pin, so that the front wheel can deflect a certain angle around the main pin to steer the automobile. In order to reduce the abrasion, a bronze bushing is pressed into a pin hole of the steering knuckle, and the lubrication of the bushing is lubricated by injecting lubricating grease by a lubricating nipple arranged on the steering knuckle. In order to make the steering flexible, a bearing is arranged between the lower ear of the steering knuckle and the fist-shaped part of the front axle. An adjustment shim is also mounted between the upper ear and the fist-shaped part of the knuckle to adjust the gap therebetween. In order to maintain the stability of straight running of the automobile, the steering portability and reduce the abrasion between tires and parts, a certain relative position must be kept between a steering wheel, a steering knuckle and a front shaft and a frame, and the installation with the certain relative position is called steering wheel positioning and also called front wheel positioning. The correct front wheel positioning should be: the automobile can run stably without swinging; the acting force on the steering wheel is not large when steering; the steering wheel has an automatic aligning function after steering; the tyre and the ground do not slip so as to reduce oil consumption and prolong the service life of the tyre. The front wheel positioning comprises the backward tilting of a kingpin, the inward tilting of the kingpin, the outward tilting of a front wheel and the toe-in of the front wheel.
The existing clamp is not strong in inclusion, one set of clamp can only adapt to a product with one angle, usually, a factory can produce more than three different steering knuckles and steering knuckles with different main pin hole included angles, each batch of produced steering knuckles needs to be replaced, the clamp is very troublesome, even if a plurality of production lines are used for producing simultaneously, orders often fluctuate, machines need to be allocated frequently, and the clamp is more troublesome to replace.
