Description

Right knuckle shell

Technical Field

The utility model relates to an auto parts technical field especially relates to a right knuckle shell.

Background

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 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. The steering knuckle 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. The steering knuckle is connected with the vehicle body through three bushings and two bolts and is connected with a braking system through a brake mounting hole of the flange plate. When the vehicle is running at high speed, the vibration transmitted from the road surface to the knuckle through the tire is a main factor to be considered in the analysis. In a driving state of the vehicle, the knuckle is subjected to a variable impact load, and therefore, the knuckle is required to have high strength. 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 end part of the steering knuckle is provided with a steering knuckle shell, and a left steering knuckle shell and a right steering knuckle shell which are symmetrically designed are respectively arranged on the left side and the right side. The existing right steering knuckle shell is more traditional in design, inconvenient to install and not firm enough in connection.

Furthermore, the shell, the flange plate, the mounting column, the upper supporting seat and the lower supporting seat are formed by integral casting.

Further, the hinge hole comprises a conical hole penetrating through the fork-shaped front side plate of the lower bearing seat and a cylindrical hole penetrating through the rear side plate.

Further, an included angle between the upper supporting seat or the lower supporting seat and the flange plate is 81 degrees.

The utility model has the advantages that: the right steering knuckle shell is designed into a spherical arc structure, so that the strength of the whole left steering knuckle shell can be improved, the weight is reduced, the flange plate is provided with the threaded hole for convenient installation, and one side of the shell is provided with the mounting column with threads, so that the assembly precision is further improved, and the loosening of screws in the use process is prevented; when the automobile steering knuckle is installed, the pin shaft penetrates through the pin shaft hole and the pin hole of the automobile steering knuckle simultaneously, then the pin shaft with threads is inserted into the upper lock hole and the hinge hole and is locked by the nut, and therefore the pin shaft is fixed. Compared with other steering knuckle shells in the market, the left steering knuckle shell has the advantages of being novel in structure, convenient to install and firm in connection.
