Description

Technical Field

[0001] This utility model relates to the field of mining dump truck technology, and more specifically, it relates to a support component and support mechanism for a mining dump truck. Background Technology

[0002] The rear support of the mining dump truck platform is a key component of the vehicle, connecting the support frame to the main beam of the chassis via a support assembly. The support assembly consists of a bottom casting, symmetrical flat plates, and bent plates, which increases the contact area with the support frame, allowing the force to be evenly transferred to the main beam of the chassis. Furthermore, the special design of each component ensures close cooperation, improving structural stability and load-bearing capacity, and guaranteeing the stable operation of the mining dump truck in harsh environments.

[0003] Currently, the rear support structure of traditional mining dump truck platforms often has some problems. The connection between the support components and the bracket and the main beam of the frame is not tight enough, which leads to uneven force transmission and stress concentration, affecting the service life and safety of the vehicle.

[0004] However, the support components in the existing technology are often relatively simple in structure and cannot effectively increase the contact area with the bracket. As a result, the force on the support components cannot be evenly transmitted to the main beam of the frame, which in turn affects the stability and reliability of the entire vehicle structure.

[0005] Therefore, in order to solve the problems existing in the rear support structure of the mining dump truck platform, this utility model proposes a support component and support mechanism for a mining dump truck. Utility Model Content
