Description

Technical Field

[0001] The utility model relates to the technical field of automobile brackets, and more specifically to a novel combined cover plate. Background Art

[0002] Leaf springs are made of multiple sheets of steel with different lengths and curvatures. After installation, the two ends naturally bend upward. When the impact force of the road surface on the wheel is transmitted, the steel plate deforms, playing a role in buffering and reducing vibration.

[0003] The formation of leaf spring: a cover plate is placed horizontally in the middle of the steel plate, and the steel plate is locked by U-bolts. Rubber is placed in the center hole at the bottom of the cover plate to prevent the cover plate from being worn and increase the service life of the cover plate. The shock absorber is stuck in the center of the two holes of the shock absorber bracket, and the locking pin passes through the shock absorber and the center of the bracket.

[0004] The existing cover plate and shock absorber are two parts. Separate processing leads to larger part errors and inaccurate part assembly positioning. Utility Model Content

[0005] The utility model provides a novel combined cover plate to solve the problems of large processing errors and inaccurate assembly positioning of parts caused by the independent design of the existing cover plate and the shock absorber.

[0007] Preferably, based on the above solution, a reinforcing rib is provided between the second arm and the side surface of the base plate.

[0008] Preferably, based on the above solution, the first support arm and the second support arm are triangular in shape, and a through hole is provided on the first support arm.

[0009] Preferably, based on the above solution, the first arm and the second arm are transitioned to the substrate through an arc.

[0010] Preferably, based on the above scheme, the depth of the sinking groove is 5 mm, the diameter of the mounting hole is 16.5 mm, and the inner end length of the mounting hole is 50.5±0.3 mm.

[0011] The utility model provides a new type of combined cover plate, in which the original cover plate and the shock absorber bracket are combined into one part, so that the cover plate and the shock absorber bracket can be accurately positioned during the installation and maintenance process; in addition, one-time processing avoids tolerance accumulation, which can effectively improve the installation accuracy and ensure the riveting accuracy, so as to improve the carrying capacity of the vehicle itself.
