Abstract
The utility model belongs to the technical field of automobile part tools, and particularly relates to a spindle head for an automobile. The spindle head for the automobile comprises a spindle rod and a ball, wherein the ball and the spindle rod adopts inclined plane transition; a square cavity is formed in the ball, the cross section of the ball is a square with four circular arc transition corners, arc-shaped concave surfaces are formed on the four outer side walls of the ball, the upper end of each square concave part is communicated with the upper end surface of the ball, concave grooves are formed in the lower parts of the inner side walls of the ball, and the concave grooves and the square concave parts are arranged on the side walls of the ball in one-to-one correspondence; and the spindle rod retracts gradually in a stepped manner from top to bottom, and transition between steps is achieved through arc-shaped surfaces. The spindle head for the automobile is reasonable in structure, and the service life of the spindle head can be well prolonged.
Description
Technical field
The utility model belongs to automotive parts apparatus technical field, relates in particular to a kind of automobile spindle nose.
Background technology
Spindle nose is indispensable mechanical part in mechanical transmission course, has important effect in mechanical transmission course.When mechanical drive, because the matching of structure and system is poor, in use often there is following defect in current spindle nose:
1, in transmission process, spindle nose driving force is uneven, and transmission effect is poor, and in transmission process, friction coefficient is larger, and serious wear affects service life, causes the replacement frequency of parts higher, cost increase.
2, existing spindle nose is connected insecurely with other parts of system, can not effectively meet the requirement of Joint strenght, even causes spindle nose in transmission process, to occur the phenomenon coming off.
So the structure design of above-mentioned spindle nose is unreasonable, make spindle nose have larger problem.
Summary of the invention
The purpose of this utility model is to solve above-described technical matters, provides a kind of rational in infrastructure, automobile spindle nose that can fine its period of service of prolongation, and its technical scheme is as follows:
Automobile spindle nose, is characterized in that, described automobile comprises axostylus axostyle and bulb with spindle nose, between described bulb and axostylus axostyle, passes through chamfered transition, in described bulb, offer square cavity, the cross-sectional plane of described bulb is the square of foursquare arc transition, on four lateral walls of described bulb, offer arc-shaped concave, described arc-shaped concave from top to bottom shrinks gradually, the lower end of arc-shaped concave is connected with the upper end lateral wall of axostylus axostyle through inclined-plane, on described arc-shaped concave, offer square depressed part, the upper end of described square depressed part communicates with the upper surface of bulb, the place, bottom of the madial wall of described bulb offers recessed groove, described recessed groove and square depressed part be corresponding setting one by one on each sidewall of bulb, described axostylus axostyle is stepped from top to bottom to be shunk gradually, passes through arcwall face transition between each ladder.
The automobile spindle nose that the utility model provides, when in use, is equipped with Automobile shaft wheel hub on the lateral wall of axostylus axostyle.Described axostylus axostyle is stepped from top to bottom to be shunk gradually, passes through arcwall face transition between each ladder.Because it is stair-stepping, be arranged so that Automobile shaft wheel hub can be good at being connected on axostylus axostyle, difficult drop-off.And in bulb, offer square cavity, in square cavity, be the square central siphon of welded hollow.On four lateral walls of described bulb, offer arc-shaped concave, described arc-shaped concave from top to bottom shrinks gradually, the lower end of arc-shaped recess face is connected with the upper end lateral wall of axostylus axostyle through inclined-plane, and the connection that is arranged so that spindle nose and miscellaneous part of arc-shaped concave is more stable.And the connection that is arranged so that bulb and square hollow central siphon of depressed part and recessed groove is more stable, easy fracture not.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with Fig. 1, illustrate embodiment:
As shown in Figure 1, automobile spindle nose, described automobile comprises axostylus axostyle 1 and bulb 2 with spindle nose, passes through inclined-plane 3 transition between described bulb 2 and axostylus axostyle 1, in described bulb 2, offer square cavity 4, the cross-sectional plane of described bulb 2 is the square of foursquare arc transition, on four lateral walls of described bulb 2, offer arc-shaped concave 5, described arc-shaped concave 5 from top to bottom shrinks gradually, the lower end of arc-shaped concave 5 is connected with the upper end lateral wall of axostylus axostyle 1 through inclined-plane 3, on described arc-shaped concave 5, offer square depressed part 6, the upper end of described square depressed part 6 communicates with the upper surface of bulb 2, the place, bottom of the madial wall of described bulb 2 offers recessed groove 7, described recessed groove 7 and square depressed part 6 be corresponding setting one by one on each sidewall of bulb 2, described axostylus axostyle 1 is stepped from top to bottom to be shunk gradually, passes through arcwall face transition between each ladder.
The automobile spindle nose that the utility model provides, when in use, is equipped with Automobile shaft wheel hub on the lateral wall of axostylus axostyle.Described axostylus axostyle is stepped from top to bottom to be shunk gradually, passes through arcwall face transition between each ladder.Because it is stair-stepping, be arranged so that Automobile shaft wheel hub can be good at being connected on axostylus axostyle, difficult drop-off.And in bulb, offer square cavity, in square cavity, be the square central siphon of welded hollow.On four lateral walls of described bulb, offer arc-shaped concave, described arc-shaped concave from top to bottom shrinks gradually, the lower end of arc-shaped recess face is connected with the upper end lateral wall of axostylus axostyle through inclined-plane, and the connection that is arranged so that spindle nose and miscellaneous part of arc-shaped concave is more stable.And the connection that is arranged so that bulb and square hollow central siphon of depressed part and recessed groove is more stable, easy fracture not.
