Problems solved by technology
[0004] However, for the cab suspension lateral stability assembly structure, the lower arm is an integral stamping and tailor-welded structure, and the overall structural strength is relatively low, which is not suitable for vehicles with heavy cab weight. At the same time, the circumferential welding of the lower arm and the lateral stabilizer The strength of this welding method is weak, and there is a gap in the left and right directions at the joint between the front suspension and the front flip support, and the vehicle will move left and right when turning

A heavy truck cab suspension lateral stable structure comprises a swing-arm supporting seat and a lateral stability part, wherein the swing-arm supporting seat is arranged on a truck body, and the lateral stability part is connected with the swing-arm supporting seat. The swing-arm supporting seat is connected with the lateral stability part through a swing-arm assembly to weaken cab suspension roll when the truck conducts steering; and the swing-arm assembly comprises a lateral connecting hole fixedly connected with a connecting hole of the swing-arm supporting seat through a lateral bolt assembly and a longitudinal connecting face fixedly connected with a connecting face of the lateral stability part through an axial bolt, the swing-arm assembly is integrally formed through forging, the integral strength of the heavy truck cab suspension lateral stable structure is high, and the probability of the phenomenon of left-right displacement of the cab is greatly reduced.
Description
technical field [0001] The invention relates to a suspension lateral stability structure of a cab of a heavy truck. Background technique [0002] The stabilizer bar assembly structure is an important part of the heavy truck full floating cab suspension system used to control the cab roll angle, and can ensure the stability of the cab and improve the service life. The design of the stabilizer bar assembly structure is directly related to the performance and reliability of the entire cab suspension system. [0003] At present, the anti-stabilizer bar assembly structure of the heavy-duty truck cab has a scissor structure formed by the upper bracket and the lower swing arm. Torsion is generated, due to the function of the stabilizer bar, the phenomenon of inconsistency in the left and right downward movement of the cab can be alleviated, and the excessive roll of the cab can be prevented. [0004] However, for the cab suspension lateral stability assembly structure, the lower ...
