Automobile aluminum alloy hem arm is also called the car under suspension, is an important part of the car, although the parts are small, but for the support of the body has a very important role, and the car's shock absorber, spring, together constitute the suspension system. The following is an introduction to the role of the aluminum alloy hem arm and matters needing attention.
Aluminum alloy hem arm is good
Cars must have done a variety of tests before the launch, if the aluminum alloy hem arm material because of the material force problem, it must have been an accident in the test, there will not be so many cars also use aluminum alloy hem arm. The overall cast lower arm strength and cost are higher than the double layer splicing.
How does aluminium alloy hem arm use
1. Cushion the vibration. The role of the swing arm is to buffer the vibration of the car during running, among which the shock absorber is used to coordinate with the swing arm to play a buffering role.
2, anti-rust, usually we can check whether the swing arm is rusty, the swing arm is located in the front tire and the car center body connection parts, easy to check, if found rusty phenomenon must be promptly to 4s shop to deal with, to prevent the accident of fracture.
3, timely replacement, lower arm problems, we should be timely replacement, otherwise there will be a serious traffic accident. The service life of the hem arm of each car is different, so we need to change it according to the maintenance manual or the Suggestions of the 4S shop.
4, anti chassis rub, usually when we drive, we should pay attention to try not to go uneven road, the road is easy to rub the site, not only chassis damage, but also easy to cause the hem arm damage, hem arm crack. Lower swing arm injury prone to steering wheel shake, run off.
5. Four-wheel positioning. After replacing the hem arm, we should carry out four-wheel positioning on the car, which is to prevent the car from running off-track or eating tires.
6, material, swing arm material is more diverse, there are aluminum alloy, cast iron, double layer stamping parts, single layer stamping parts, all kinds of materials have advantages and disadvantages, stamping parts toughness is better, but the strength is not enough, easy to break by impact.
The above is the introduction of quanshun xiaobian aluminum alloy arm relevant knowledge, I hope to help you.
