Technology of Semi Trailer Suspension Manufacturer in China
A semi-trailer suspension assembly belongs to the technical field of semi-trailer suspension. It includes a front bracket, a leaf spring, a balance arm, a middle bracket, a rear bracket, a first leaf spring seat, and a second leaf spring seat. One of its characteristics is that the first leaf spring seat and the second leaf spring seat are respectively connected with the middle bracket and the rear bracket through the shock absorption device.
The upper part of the middle bracket is provided with a balance arm, which is connected with a leaf spring. The end of the leaf spring is provided with a clamping hook and limit blocks are installed on the inner wall of the upper part of both ends of the balance arm. A groove is designed in the middle of the lower end of the limit block. One end of the inner side of the groove is in contact with the clamping hook, and the outer end of the groove is clamped with the clamping hook.
The effect of its technology is that the suspension assembly manufactured in China has the advantages of good vibration damping effect, which prevents the end of the suspension from falling off and improves its service life and driving safety.
Introduction of Semi Trailer Suspension Manufacturer in China
At present, the suspension of semi-trailer adopts leaf spring balance suspension for manufacturers in China. Due to the influence of road roughness and the influence of alternating load generated in vehicle starting and braking conditions, the suspension bracket of semi-trailer will also be influenced by the action of alternating load. Under the repeated action of this alternating load, crack initiation, expansion, and sudden rupture may occur, which is a potential safety hazard.
Since the vibration of the vehicle during transportation will affect the quality and service life of the vehicle, in order to solve the impact of vibration, in the frame structure of the semi-trailer, the balance arm swings under different road conditions to reduce the impact from the wheels and suspension. Therefore, during the swinging process of the balance arm, the end of the suspension easily crosses the highest point of the arc surface and escapes from the balance arm. This can cause vehicle failures and accidents.
In order to improve the safety and service life of semi-trailer cargo transportation, it is necessary to have the most ideal structure of the existing semi-trailer suspension to achieve the effect of reducing vibration and solve the problem of the suspension end snapping out of the balance arm.
Thoughts on Solution of Suspension Failure
In order to solve the above technical problems, the present technology provides a semi-trailer suspension assembly, which effectively solves the problem that the current semi-trailer suspension system has large vibration caused by uneven road conditions and excessive vibration causeing the end of the suspension snap out of the balance arm. The problem is that the semi-trailer has a short service life and a low safety factor during transportation.
The purpose is to design a suspension system that has a good vibration reduction effect and can avoid the end of the suspension from falling off. In order to achieve the aformentioned goal, the solution used with this technology to solve the technical problem is to include the suspension assembly of the semi-trailer with a front bracket, a leaf spring, a balance arm, a middle bracket, and a rear bracket.
The first plate spring seat is arranged between the front bracket and the middle bracket. A second plate spring seat is arranged between the middle bracket and the rear bracket. An adjustment pull rod is connected between the first plate spring seat and the front bracket, while a fixing rod is connected between the second plate spring seat and the middle bracket. With this setup the first leaf spring seat and the second leaf spring seat are respectively connected with the middle bracket and the rear bracket through a shock absorbing device.
