Signs of front horn damage include:
Tire problems: car tires may eat the tire, deviation phenomenon, this is because the Angle damage affects the normal work of the tire, lead to uneven tire wear.
Brake problems: brake may feel obvious jitter, this is because the Angle damage affects the stability of the brake system, may lead to bearing and drive shaft damage.
Abnormal front wheel wear: the front wheel may appear abnormal wear, direction poor return, this is because the damage of the sheep Angle affects the normal rotation and positioning of the front wheel.
Abnormal body noise: when the vehicle is driving, there may be abnormal body noise fault symptoms, this is because the damage of the horn leads to the abnormal movement of the mechanical parts.
Vehicle stability problems: horn damage may affect the stability of the vehicle, comfort and handling, in serious cases may lead to the vehicle can not run, and even accidents.
The automobile horn is a part of the steering knuckle assembly, is responsible for connecting the wheel and suspension, bears the load on the front of the automobile, and supports the front wheel to rotate around the kingpin to realize the automobile steering. Therefore, the health of the shofar is critical to the performance and safety of the vehicle. Once found to be damaged, should be replaced in time to ensure driving safety.
What is the role of the car horn?
The car's horn is called "steering knuckle" or "steering knuckle arm", which is the axle head that bears the steering function at both ends of the I-beam in front of the car, and it is a bit like the horn of the sheep, so it is commonly known as "the horn of the sheep".
The main function of the front horn of the car is to transfer and bear the front load of the car, support and drive the front wheel to rotate around the kingpin, so that the car turns.
The front horn of an automobile, , also known as the steering knuckle or steering knuckle arm, is the axle head at both ends of the front I-beam bearing the steering function. Its shape is a bit like a goat's horn, so it is called "goat's horn". steering knuckle is an important part of automobile steering system. can make the vehicle run stably, stably, transmit the driving direction sensitively and ensure the accuracy of driving. In the driving state, steering knuckle bears variable impact load, therefore requires it to have high strength. There are two arms on the steering knuckle on one side of the integrated front axle near the steering disc, are connected with the longitudinal and transverse tie rod respectively, there is only one arm on the other side of the steering knuckle connected by the transverse tie rod. This design allows the car to steer smoothly, at the same time to ensure safety and stability.
In addition, the car horn is also called the "steering knuckle" or "steering knuckle arm", it is the axle head of the front I-beam with the steering function. The structure of the horn is a bit like a horn, , so it is commonly known as "ox horn". steering knuckle can make the car smoothly, sensitive transmission of the direction of travel, is one of the important parts of automobile steering.
The function of the steering knuckle is to transfer and bear the load of the front of the car, support and drive the front wheel to rotate around the kingpin and make the car turn. In the driving state of the car, it is subjected to variable impact loads, so it is required to have a high strength.
Extended data: There are two arms on the steering knuckle on one side of the integrated front axle near the steering disc, which are connected to the longitudinal tie rod and the transverse tie rod respectively, and only one arm on the other side of the steering knuckle connected by the transverse tie rod.
The connection mode of the steering knuckle arm on the steering knuckle is mainly connected through the 1/8-1/10 cone and spline, which is firmly connected and not easy to loosen, but the steering knuckle processing process is more.
The steering knuckle arm is mostly forged from the same material as the steering knuckle, and it reaches the same hardness with the steering knuckle through heat treatment. Generally, increasing the hardness can increase the fatigue life of the parts, but the hardness is too high, the toughness of the original is too poor, and the machining is difficult.
1, the steering knuckle arm or bushing allows a clearance of 0.3-0.5 mm. If excessive wear, should be replaced.
2. When assembling, the bushing should be oiled. And fill the two liners with lithium grease.
