Clamping device used for transmission shaft of motor vehicle

Abstract

The invention discloses a clamping device used for a transmission shaft of a motor vehicle. The clamping device comprises a fixed shell sleeve (1) and a rotary shell sleeve (5). An iron bead circular groove (6) is formed in the inner planar surface of the fixed shell sleeve (1). Another iron bead circular groove (6) is formed in the outer planar surface of the rotary shell sleeve (5). The rotary shell sleeve (5) is arranged in the fixed shell sleeve (1), and a plurality of iron beads (7) are arranged between the two iron bead circular grooves (6). The iron beads (7) are fixedly connected through a clamping sleeve (8). An oil conveying pipe (10) is arranged in the rotary shell sleeve (5). An upper oil pipe (11) and a lower oil pipe (12) which are connected with the oil conveying pipe (10) are arranged in the rotary shell sleeve (5). A pressure applying column (13) is fixed to the front portion of the rotary shell sleeve (5). A pressure applying area (14) is arranged in the pressure applying column (13), and the pressure applying area (14) and the upper oil pipe (11) are arranged in a through mode.

Description

technical field [0001] The invention relates to a transmission shaft clamping device for a motor vehicle. Background technique [0002] At present, the transmission shaft has become an important part of the motor vehicle. Due to the different sizes of the motor vehicle, it is necessary to use a transmission shaft with a matching length. Some large vehicles, such as (road rescue vehicles, container trucks, transport vehicles), etc., due to their own drive shafts are too long when the engine is running at high speed, the drive shaft tends to be eccentric, causing the vehicle to vibrate and cannot drive at high speed , Seriously affect the stability and safety of motor vehicles, and pose a threat to the safety of drivers. Contents of the invention [0003] The object of the present invention is to provide a transmission shaft clamping device for a motor vehicle to solve the problems raised in the above-mentioned background technology. [0004] To achieve the above object, t...
