Embodiment Construction

[0023] Please see figure 1 , is an assembly drawing of the steering drive axle drive axle support device provided by the first embodiment of the present invention.

[0024] Such as figure 1 As shown, the steering drive half shaft is divided into an inner half shaft 10, an outer half shaft 8 and a hinge device 9 connecting the inner and outer half shafts together. The inner half shaft 10 cooperates with the side gear installed in the drive axle housing 12, the outer half shaft 8 cooperates with the steering hub 7, and the power transmission and steering are realized through the hinge 9 between the two.

[0025] The part of the inner half shaft 10 close to the side gear is located in the drive axle case 12, and there is liquid lubricating oil in the drive axle case 12.

[0026] In this embodiment, at the seam of the drive axle housing 12, a driving half shaft support device 11 is installed, which is used to connect the driving axle housing 12 and the inner half shaft 10, so th...

Abstract

The invention discloses a steering drive axle driving axle shaft support device, comprising an outer sleeve 1, an elastic rubber 2 and an inner bushing 3; wherein, the external diameter of the outer sleeve 1 closely transition fits with the drive axle shell 12 rabbet; the inner bushing 3 and the outer sleeve1 becomes an integral through the elastic rubber 2, the inner bushing 3 and the inner axle shaft 10 clearance fit with each other; the inner bushing 3 has the installation position of the oil seal 6 at one end of the drive axle shell rabbet, preferentially, wherein the inner diameter of the inner bushing 3 has major diameter section and minor diameter section; the inner diameter clearance fitting with the inner axle shaft 10 has minor diameter section; the interface of the major diameter section and the minor diameter section forms a treppe towards the outside of the drive axle shell 12, the treppe being the installation position of the oil seal 6. The steering drive axle driving axle shaft support device has the advantages of effectively supporting the drive axle driving axle shaft inner axle shaft and preventing the liquid lubricating oil in the drive axle shell from leaking.

Description

technical field [0001] The invention relates to automobile technology, in particular to a steering drive axle drive axle support device. Background technique [0002] In the work of trucks, light vehicles, etc., the engine generates power, which is transmitted to the drive axle through the clutch, transmission (4X4 including transfer case) and drive shaft, and the driving force is distributed to the left and right steering drive axles by the drive axle differential axle gear , the steering drive shaft drives the wheels to rotate to make the car move. In addition to transmitting power, the steering drive shaft also changes the direction of power transmission according to the turning needs of the vehicle. [0003] The steering drive half shaft is divided into an inner half shaft, an outer half shaft and a hinge device connecting the inner and outer half shafts together. One end of the inner half shaft matches the half shaft gear in the drive axle housing, the other end is co...
