Description

Technical Field

[0001] The utility model relates to the technical field of steering knuckle equipment, in particular to an automobile steering knuckle with a quadrangular pyramid structure design. Background Art

[0002] With the development of science and technology and the progress of the times, people's means of transportation are becoming increasingly abundant, and automobiles are one of them. In the process of manufacturing automobiles, many parts are needed, and the selection of automobile steering knuckles is particularly critical. Automobile steering knuckles, also known as "ram's horns", are one of the important parts in automobile steering axles, which can make the car run stably and sensitively transmit the direction of travel. The function of the steering knuckle is to transmit and bear the front load of the car, support and drive the front wheels to rotate around the kingpin to steer the car. The existing automobile steering knuckles, during use, adjust the gap when the steering knuckle is connected to the end of the front axle of the car by changing the thickness of the gasket, which makes it poor in flexibility and weak in assembly efficiency.

[0003] The application number is CN202220544975.0, which discloses an anti-fracture automobile steering knuckle, and relates to the technical field of automobile steering knuckle, including a fixed seat, one side of the fixed seat is connected to a journal, and a first fork ear is installed above the other side of the fixed seat, a threaded area is provided on the inner side of the first fork ear, and a movable tube is threadedly connected to the inner side of the threaded area, and the outer wall of the movable tube is connected to a fixed rod, and a reserved groove is provided on the outer wall of the first fork ear, and the reserved groove and the fixed rod are through-distributed, and a second fork ear and a gasket are installed below one side of the fixed seat, and the gasket is installed at the bottom end of the movable tube. In the utility model, by manually rotating the fixed rod, it drives the movable tube and the gasket to move downward, so as to complete the thickness required by the gasket when the steering knuckle is connected to the front axle of the automobile, and adjust the gap, so that people do not need to find a suitable gasket, and can directly adjust the height of the gasket moving downward, thereby achieving the purpose of improving assembly efficiency and excellent flexibility.

[0004] The anti-fracture automobile steering knuckle disclosed in the above document has the following defects: when the steering knuckle is in use, the structure is not provided with a corresponding linkage structure to enable the steering knuckle to drive the wheels to achieve the steering function, and it is also impossible to achieve steering of the wheels on both sides at the same time, thereby reducing the flexibility of the steering knuckle.

[0005] It can be seen from this that the existing automobile steering knuckle does not have the function of steering the wheels, and it is necessary to improve the existing deficiencies and provide a function that can flexibly steer the wheels. Utility Model Content
