Description

Technical Field

[0001] The utility model relates to an adjusting device for a brake cylinder push rod of an armored vehicle, belonging to the technical field of general assembly of tracked armored vehicles. Background Art

[0002] When assembling the brake cylinder in the brake system of tracked self-propelled artillery and rocket launcher vehicles, the top rod of the brake cylinder needs to adjust its extension length after assembly to adjust the total clearance of the brake friction pair. In fact, after assembly, the adjustment rod at one end of the brake cylinder is adjusted to adjust the extension length of the top rod, and the adjustment rod needs to be rotated about 80 times. Since the brake cylinder is installed below the front deck of the armored vehicle, the space where it is assembled is very narrow. This narrow space makes it impossible for the operator to use an electric tool to rotate the adjustment rod when rotating the adjustment rod. The electric tool, such as an electric wrench, can only use an ordinary ratchet wrench to rotate the adjustment rod. Due to the limited operating space, the operator can only rotate the adjustment rod by a quarter of a turn each time when using the ratchet wrench. This will cause the ratchet wrench to be rotated about 300 times to adjust the extension distance of the top rod of the brake cylinder on one side. The operator of the two brake cylinders equipped on this vehicle needs to manually rotate the ratchet wrench about 600 times. This method has a low adjustment efficiency, which has a certain impact on the assembly efficiency of the whole vehicle and has a high labor intensity for the operator.

[0003] Therefore, it is urgent to propose a novel armored vehicle brake cylinder push rod adjustment device to solve the above-mentioned technical problems. Utility Model Content
