Embodiment 1

[0029] Such as figure 1 , figure 2 They are schematic diagrams of the structure of the axle box 1 and the countershaft box 2 of the axle drive unit respectively. In the field, the axle box 1 is also called the axle box. As a drive axle structure, one end of the axle box 1 is connected to the axle box 2, The other end symmetrically extends two circular connection plates 1-1, the connection plates 1-1 are parallel to each other and are provided with a circular hole 1-2 with a coaxial center, and the subshaft case 2 is also provided with a circular hole 2-1, the circular hole Two 2-1 are parallel to the axis of the circular hole 1-1.

[0030] Such as image 3 a. image 3 b. image 3 c. A rotatable transmission shaft 11 is installed in the axle box 1. Both ends of the transmission shaft 11 are exposed from the axle box 1. A rotatable half shaft 21 is installed in the subshaft box 2. One end of the half shaft 21 extends out of the subshaft box 2. The hub 4 is driven by the un...

Embodiment 2

[0033] Such as Figure 5 It is the assembly drawing of the automobile front axle lifting axle based on the bridge drive unit, a pair of bridge drive units of embodiment 1 are symmetrically installed on one end of the main half shaft 5, and the transmission assembly includes the driving wheel 23 and the transmission on the main half shaft 5. The driven wheel 24 on the shaft 11, the surfaces of the driving wheel 23 and the driven wheel 24 are coupled to each other, the driving wheel 23 drives the driven wheel 24 on the two transmission shafts 11 to move in opposite directions, and the driven wheel 24 can be around the drive wheel 23 axis For planetary revolution, the driving wheel 23 and the driven wheel 24 are preferably pot gears 23 and bevel gears 24, but are not limited thereto. Such as Image 6, each auxiliary shaft box 2 is driven by the telescopic mechanism 6 on the same side, so that the two shaft boxes 1 rotate around the main half shaft 5 to form an included angle, an...

Abstract

The invention discloses a bridge drive unit and an automobile lifting axle based on the bridge drive unit. The bevel gears in the axle boxes on both sides are driven by basin gears arranged on the main half shaft, so that the transmission shafts connected with the bevel gears in the axle boxes The half shaft is driven by the transmission assembly, and then the universal joint and the wheel hub are rotated. The two shaft boxes are hinged to each other and connected to the main half shaft. They can rotate around the main half shaft and are equipped with a locking mechanism. The side can push the axle box to rotate. The automobile lifting axle based on the bridge-connecting drive unit of the present invention can lift and lower the chassis of the automobile and improve the barrier-crossing ability.

Description

technical field [0001] The invention relates to the technical field of drive axles, in particular to a bridge drive unit, and also to an automobile lifting axle based on the bridge drive unit. Background technique [0002] The chassis of the car has always been driven by one bridge to drive the left and right wheels. At present, there is no drive bridge structure that can change the height of the chassis according to the terrain. Therefore, the obstacle crossing height of the existing off-road vehicles is below the radius of the wheel. Assuming a wheel with a diameter of 1000mm, about Can cross obstacles less than 500mm. So existing off-road vehicle all can not satisfy the demand of off-road situation. Contents of the invention [0003] In view of the existing problems, the present invention aims to provide a drive axle that can be lifted and changed in height, so that the height of the chassis can be adjusted, and the vehicle’s ability to cross obstacles is increased. ,...
