Problems solved by technology

[0002] Some special working conditions often require vehicles to have a higher clearance, such as inter-row weeding, loose soil, fertilization, soil cultivation, etc. for mid-term field management of tractors, usually by increasing the diameter of the road wheel to complete the clearance. However, this will make it easier for the tractor to sink when performing field operations, making it impossible to perform field operations in sticky fields, and different application environments have different requirements for vehicle clearance, such as plowing, plowing, sowing, harvesting, road surface Conventional operations such as transportation require a ground clearance of 30-50 cm, while mid-term field management operations such as weeding between rows, loosening soil, fertilizing, and soil cultivation require a higher ground clearance, but cultivators that can complete mid-term field management operations, It is not suitable for conventional tractor operations, so different tractors need to be configured in order to complete ordinary routine operations and field management operations, which not only requires a large investment but also has low equipment utilization

Embodiment 1

[0015] like figure 1 As shown, the high ground clearance vehicle drive axle includes a housing 1, a power output shaft 3 is installed in the bridge tube 2 on both sides of the housing 1, and side transmission boxes 4 are fixedly installed at both ends of the housing 1, respectively. The side transmission box 4 includes:

[0016] Upper box body 41, the drive shaft 5 of the side transmission box is installed in the rotation of the upper box body 41, and the drive shaft 5 of the side transmission box is connected with the spline of the power output shaft 3; An upper driving bevel gear 6 is fixedly installed, and an upper driven bevel gear 7 meshing with the upper driving bevel gear 6 is also rotatably installed in the upper box 41;

[0017] The lower box body 42, the wheel half shaft 8 is installed in rotation in the said lower box body 42, the lower driven bevel gear 9 is fixedly installed on the said wheel half shaft 8, and the lower driven bevel gear 9 is also rotatably insta...

Embodiment 2

[0022] like figure 2 As shown, the structure of the second embodiment is basically the same as the structure of the first embodiment. The rotating device is installed on the upper box body 41, and the wheel steering arm 13 is fixedly arranged on the variable ground clearance box body 43; 41 between the bearings 14 .

[0023] The upper end of the variable clearance box 43 is installed on the upper box 41 through a rotating device, and the wheel steering arm 13 is fixed on the variable clearance box 43; the wheel steering arm can complete the wheel steering under the steering rod. Steering can be used as the steering drive axle of the vehicle, and the variable ground clearance box body 43 installed between the upper box body 41 and the lower box body 42 improves the ground clearance of the vehicle. The ground clearance of the vehicle can be changed, and the ground clearance can be adjusted according to the operating conditions. The adjustment is convenient and reliable to mee...

Abstract

The invention discloses a high ground clearance vehicle drive axle. The drive axle comprises a shell, wherein power output shafts are installed in axle tubes at the two sides of the shell; lateral transmission cases are fixedly installed at the two ends of the shell; each lateral transmission case comprises an upper case body, a lower case body, a variable ground clearance case body and an intermediate power transfer device; a lateral transmission case driving shaft connected with one power output shaft by a spline is installed in the upper case body in a rotary manner; an upper driving bevel gear meshed with the lateral transmission case driving shaft is fixedly installed on the lateral transmission case driving shaft; an upper driven bevel gear meshed with the upper driving bevel gear is also installed in the upper case body in a rotary manner; a wheel half shaft is installed in the lower case body in a rotary manner; a lower driven bevel gear is fixedly installed on the wheel half shaft; a lower driving bevel gear is also installed in the lower case body in a rotary manner; the two ends of the variable ground clearance case body are installed on the upper case body and the lower case body; and the intermediate power transfer device is arranged between the upper driven bevel gear and the lower driving bevel gear. The drive axle has the following beneficial effects that: the variable ground clearance case body improves the ground clearance of the vehicle; the ground clearance of the vehicle can be changed by replacing the variable ground clearance case body; and the ground clearance can be adjusted according to the operation conditions.
