Description

Technical Field

[0001] This utility model relates to the field of braking technology, specifically to a fully suspended disc brake bridge device. Background Technology

[0002] Currently, the axles on the market include several structures such as fully suspended drum brakes, semi-suspended drum brakes, and semi-suspended disc brakes. Compared to semi-suspended structures, the advantage of a fully suspended structure is that the half-shaft only bears torque, while the bending moment is borne by the axle housing. Disc brakes, compared to drum brakes, have the advantages of better braking performance, better heat dissipation, simpler and more convenient maintenance, and are suitable for high-speed vehicles. However, there is a lack of axles on the market that possess both of these structures.

[0003] Therefore, a fully suspended disc brake bridge device is proposed. Summary of the Invention
