Abstract
The utility model discloses a highland gap drive axle which comprises a main speed reducer and two semiaxis. Each semiaxis is connected with the main speed reducer through a drive mechanism. The drive mechanism comprises a main drive shaft and a drive shaft. The main drive shaft is connected with the output end of the main speed reducer, the main drive shaft and the drive shaft are connected through a bevel gear set I, the drive shaft and the semiaxis are connected through a bevel gear set II, and the main drive shaft is arranged above the semiaxis. Due to the fact that the main drive shaft and the main speed reducer are supported to a higher position through the drive shaft, and gaps from the ground of the main drive shaft and the main speed reducer are increased, so the main drive shaft and the main speed reducer are not prone to run into obstacles, the drive axle is prone to pass, and adaptation performance to field road conditions of agricultural vehicles is improved.
Description
Technical field
The utility model relates to a kind of drive axle.
Background technology
The drive axle of existing automobile comprises main reduction gear, two transmission shafts and two semiaxis, two transmission shafts basically semiaxis on an axis, the height of drive axle is determined by wheel size, because wheel size is that certain restriction is arranged, therefore, drive axle is all not bery high.Farm vehicle need to be in the field farming, because the road conditions in field are special, obstacle is more, particularly the long-living field of crop is arranged, need to avoid crop, and existing drive axle is easily run into crop or other obstacle, affects the farm vehicle operation.
Summary of the invention
The technical problems to be solved in the utility model is: a kind of high-clearance drive axle is provided, makes its road conditions comformability to the field good.
In order to solve the problems of the technologies described above, the utility model comprises main reduction gear and two semiaxis, two semiaxis respectively are connected with main reduction gear by a transmission device, described transmission device comprises main driving axle and side transmission shaft, main driving axle is connected with the main reduction gear mouth, main driving axle is connected the bevel gear set I and connects with the side transmission shaft, the side transmission shaft is connected by the bevel gear set II with semiaxis, and main driving axle is positioned at the semiaxis top.
For the ease of turning to, described each side transmission shaft rotates by bearing and is arranged on the rotary support, the dead in line of rotatably supported rotation axis and side transmission shaft, and rotatably supported lower end is fixed with steering swivel, and steering swivel is connected with the axle housing of semiaxis.
In order to make it simple in structure, described bevel gear set I and bevel gear set II include two finishing bevel gear cuters that are meshed.
In order to make its transmission stability good, described side transmission shaft is obliquely installed, and the upper end of two side transmission shafts is all drawn close to the centre, and main driving axle and semiaxis all are horizontally disposed with.
The beneficial effects of the utility model are: the utility model supports to the higher position by the side transmission shaft with main driving axle and main reduction gear, increase its ground Clearance, make it not allow to run into obstacle, so that the crossing ability of drive axle is good, improved the road conditions conformability of farm vehicle to the field.
Description of drawings
Fig. 1 is the utility model structural representation;
