Automobile aluminum alloy lower arm is also called automobile lower suspension, which is an important part of the car. Although the parts are small, it plays an important role in supporting the body. It forms the suspension system together with the shock absorber and spring. The following describes the function and precautions of aluminum alloy lower arm.

How about aluminum alloy lower arm

All kinds of tests must have been done before the car was put on the market. If there is something wrong with the material of the aluminum alloy lower arm, something must have happened during the test, and there will not be so many cars still using aluminum alloy lower arm. Integral casting in the lower arm strength and cost, are higher than the double-layer splicing.

How to use aluminum alloy lower arm

1. The function of the swing arm is to cushion the vibration of the car during driving. The shock absorber is used to cooperate with the swing arm to cushion the vibration.

2. Rust proof. Usually, we can check whether the swing arm is rusty by ourselves. The position of the swing arm is located in the parts connecting the front wheel tire and the center body of the car. It is easy to check. If rust is found, we must go to the 4S store in time to prevent fracture and accidents.

3. Timely replacement, when there is a problem with the lower arm, we should replace it in time, otherwise serious traffic accidents will occur. The service life of the lower arm of each car is different. We need to replace it according to the maintenance manual or the suggestion of the 4S store.

4. To prevent the chassis from being scratched. When driving, we should pay attention not to take uneven roads as far as possible. Such roads are easy to scratch the ground, which not only causes damage to the chassis, but also easily causes damage to the lower arm and cracks in the lower arm. Lower arm injury prone to steering wheel jitter, deviation and other phenomena.

5. Four wheel alignment. After replacing the lower arm, we need to carry out four-wheel alignment. The four-wheel alignment is to prevent the car from running off the track or eating tires.

6. Materials and swing arm materials are quite diverse, including aluminum alloy, cast iron, double-layer stamping parts and single-layer stamping parts. All kinds of materials have advantages and disadvantages. The toughness of the stamping parts is better, but the strength is not enough, and it is easy to fracture when impacted.
