Technical Field
The invention relates to a power transmission system of a new energy vehicle, and particularly discloses a fan split differential case of a new energy recreational vehicle.
Background
With the decreasing of petroleum resources and the increasing of air pollution, new energy vehicles normally become a development hot door, and meanwhile, the new energy vehicles also move forward more conveniently and comfortably, and the body weight of a new energy rear axle assembly at the present stage is too large, so that the resource waste is caused, and the motor burden is also heavier.
Disclosure of Invention
In order to meet the requirement of portability of new energy vehicles, particularly new energy recreational vehicles, the mini split differential case body of the new energy recreational vehicle is reasonable in structure, high in space utilization rate, convenient to install and maintain and high in resource utilization rate.
The technical scheme adopted by the invention is as follows: a split differential box body of a new energy recreational vehicle fan is formed by buckling a left half shell and a right half shell, wherein bolt holes are symmetrically formed in the peripheries of the two half shells, and the left half shell and the right half shell are fixedly connected through bolts; the left half shell and the right half shell are provided with power output holes for connecting a rear axle half shaft, and the left half shell is provided with a power input hole for connecting a motor; a connecting motor flange and a connecting rear axle flange are respectively arranged around the power output hole and the power input hole; the connecting motor flange is connected with a middle yoke plate of the motor through a bolt; the flange for connecting the rear axle is connected with the flange on the rear axle through a bolt; the rear axle connecting flange comprises four rear axle connecting bolt holes which are circumferentially and uniformly distributed around the power output hole and an annular upright post arranged at the outer edge of the power output hole, reinforcing ribs are arranged between the inner ring and the outer ring of the annular upright post for connection, the rear axle connecting bolt holes divide the annular upright post into four arc-shaped weight unloading grooves with equal size, and the reinforcing ribs are connected between the rear axle connecting bolt holes and the annular upright post; the top surface of the half shell forms a certain descending slope from the annular upright post to the edge.
Furthermore, the outer part of the annular upright column is symmetrically connected with a triangular fixed support which is connected between the annular upright column and the half shell.
Furthermore, the arc-shaped weight-unloading groove is divided into at least two sections by reinforcing ribs.
Furthermore, the edge of the differential case is positioned at two sides of the flange connecting the rear axle, and two process pressure points are symmetrically arranged.
Furthermore, the connecting motor flange comprises three connecting motor bolt holes, wherein one connecting motor bolt hole is positioned on the central axis of the left half shell and forms an equilateral triangle position relation with the other two connecting motor bolt holes around the power input hole.
Furthermore, a reinforcing panel protruding out of the surface of the shell is arranged in the area between the three bolt holes for connecting the motor, and a weight-unloading groove is formed in the reinforcing panel.
The invention has the beneficial effects that:
according to the invention, through the arrangement of the weight-unloading groove and the arrangement of the annular upright post, the problems that the existing small-sized vehicle differential case body such as a new energy recreational vehicle is overlarge in weight and easy to damage can be reasonably solved, the resource waste is reduced, the motor burden is reduced, and the raw material cost is reduced. Meanwhile, the differential motor assembly is convenient to install, high in strength and not easy to damage.
