Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of vehicle mounts, and particularly relates to an eddy current retarder mount structure for a pure electric mine dump truck. Background Art
[0002] A mine truck, which belongs to off-road vehicles, is mainly used in mines and engineering. It is more durable and has a greater load capacity than ordinary trucks. Mine trucks are designed to meet the requirements of mine construction operations. Therefore, the whole vehicle and its components of mine trucks are considered for the mine operation environment and are designed and manufactured for such users.
[0003] At present, mine trucks generally work in open-pit mining areas with harsh road conditions. The road conditions in the mining area are harsh, the road surface is bumpy, and during driving, the eddy current retarder will jump up and down due to the vehicle bumping. If the displacement of the eddy current retarder is too large, it will cause a severe impact on the drive shaft. If the strength and stiffness of the eddy current retarder mount bracket are insufficient, the bracket will be deformed or even broken. If the stiffness of the shock pad is insufficient, its durability will be poor. In this way, the eddy current retarder may have a large displacement or even separation from the eddy current retarder, and in severe cases, it will damage the drive shaft and axle, and even cause safety accidents.
[0004] Therefore, a reliable eddy current retarder mounting device is needed to support the eddy current retarder and dampen its vibration. Summary of the Utility Model

[0011] As can be seen from the above technical solutions, a suspension structure of an eddy current retarder for a mining vehicle provided by the present utility model has left and right suspension brackets and a mounting bracket cooperatively arranged. The structural strength of the mounting bracket for assembling the eddy current retarder can be increased through the first mounting section and the second mounting section, avoiding deformation and fracture of the suspension bracket of the eddy current retarder, which may cause a large displacement of the eddy current retarder mounted thereon and damage the drive shaft and the axle, and improving the structural reliability.
