Description

Car transmission shaft anchor clamps

Technical Field

The utility model relates to the field of transmission shaft clamps, in particular to an automobile transmission shaft clamp.

Background

Typically, a propeller shaft is provided between the gearbox and the drive axle for effecting power transfer from the gearbox to the drive axle. In the prior art, the assembly process adopted by the transmission shaft is as follows: frame (bottom face up), axle assembly, assembly of one end of a transmission shaft, frame overturning (right side up), assembly of a gearbox, and assembly of the other end of the transmission shaft and the gearbox.

In the process, the frame overturning process is involved, at the moment, one end of the transmission shaft is connected with the rear axle, while the other end of the transmission shaft is not connected with related parts, and accidents such as falling and collision of the transmission shaft are easy to occur in overturning. Meanwhile, in the overturning process, the transmission shaft swings greatly, and the middle support, the universal joint and other parts are extremely easy to damage.

Aiming at the problems and potential safety hazards existing in the transmission shaft in the frame overturning process, nylon ropes are commonly used at present to fix the front end of the transmission shaft on a frame cross beam or a longitudinal beam, so that the transmission shaft is prevented from falling and colliding when the frame is overturned. However, nylon rope tying methods are prone to the following problems:

1. nylon ropes are unreliable during use. The knotting methods and forces adopted by different operators are different, so that phenomena such as nylon rope sliding buckles and the like are very easy to occur, and safety accidents such as transmission shaft falling and the like occur;

2. after binding with nylon ropes, the transmission shaft and the cross beam can slide relatively in the overturning process, so that the transmission shaft and the paint layer of the cross beam are damaged, scratches appear, and the appearance effect of the whole automobile is affected. In addition, the sliding process can damage the middle support and other parts of the transmission, so that oil seals leak oil, and the damping performance is reduced.
