Abstract
The utility model discloses a lightweight semi-axis for car, including semi-axis outer end, semi-axis middle part and semi-axis inner, the semi-axis outer end is provided with the flange, and semi-axis inner is provided with the integral key shaft, the semi-axis middle part is equipped with the centre bore, and centre bore outer fringe end is equipped with the peripheral hole. The utility model discloses realize full floating hollow semi-axis, through establishing centre bore and peripheral hole, on the basis of guaranteeing semi-axis result of use, the biggest effect subtracts the heavy to the semi-axis for the semi-axis can reduce 10% ~ 15% of former solid axle, makes whole car weight reduce, and it is effectual to fall heavy, reduces manufacturing cost, does benefit to the energy saving and emission reduction of vehicle.
Description
Technical Field
The utility model relates to an automobile semi-axis technical field specifically is a lightweight semi-axis for car.
Background
The half shaft, also called as a driving shaft, is a shaft for transmitting torque between a variable box speed reducer and a driving wheel, and the inner end and the outer end of the half shaft are respectively provided with a universal joint which is respectively connected with a speed reducer gear and a hub bearing inner ring through splines on the universal joints. The solid automobile body is solid generally, so that the weight of the whole automobile is increased, the weight reduction effect is poor, the manufacturing cost is increased, and the energy conservation and emission reduction of the automobile are not facilitated.
In view of this, we propose a lightweight half-shaft for an automobile to solve the above problems.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a lightweight semi-axis for car to solve the problem that proposes in the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a lightweight semi-axis for car, includes semi-axis outer end, semi-axis middle part and semi-axis inner, the semi-axis outer end is provided with the flange, and semi-axis inner is provided with the integral key shaft, the semi-axis middle part is equipped with the centre bore, and the centre bore outer fringe end is equipped with the peripheral hole.
Preferably, the half shaft outer end, the half shaft middle part and the half shaft inner end are all in friction welding with each other.
Preferably, the peripheral holes are distributed in the middle of the half shaft in an annular array.
Preferably, the aperture of the central hole is 2-5 times of that of the peripheral holes.
Preferably, the aperture of the central hole corresponds to the sum of the aperture of the peripheral holes plus the linear distance between the two hole edges.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses realize full floating hollow semi-axis, through establishing centre bore and peripheral hole, on the basis of guaranteeing semi-axis result of use, the biggest effect subtracts the heavy to the semi-axis for the semi-axis can reduce 10% ~ 15% of former solid axle, makes whole car weight reduce, and it is effectual to fall heavy, reduces manufacturing cost, does benefit to the energy saving and emission reduction of vehicle.
Drawings
FIG. 1 is a schematic structural view of the present invention;
fig. 2 is the cross-sectional view of the middle part of the half shaft of the utility model.
In the figure: 1 semi-axis outer end, 2 semi-axis middle parts, 3 semi-axis inner ends, 4 central holes, 5 peripheral holes.
