Description
Technical field
The utility model design vehicle semiaxis, is specifically related to a kind of light bus rear axle shaft.
Background technology
Semiaxis is the solid axle of transferring power between diff and drive wheel, and it is inner is connected with differential side gear, and outer end is then connected with the wheel hub of drive wheel, brake wheel or brake disc etc.; The moment of torsion transmitted from diff is through semiaxis, wheel hub etc., and finally passing to wheel, is a strength member of transmitting torque in transmission system.Semifloating axle shaft, except transmitting torque, also will bear the moment of flexure that vertical power, side force and longitudinal force act on; Be usually used on light bus, but existing light bus rear axle semi-axis structure is unstable, easily breaks down or causes the accident, causing loss.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of Stability Analysis of Structures and the light bus rear axle shaft of use safety.
For solving the problem, the utility model provides a kind of light bus rear axle shaft, comprise flange, axis body and spline body, described axis body is provided with successively flange, the first oil sealing coordinates platform, bearing fit platform, the second oil sealing coordinates platform, connection for transmission circle and spline body, described first oil sealing coordinates platform, bearing fit platform, the second oil sealing coordinates platform, the diameter of section of connection for transmission circle reduces successively, and described flange is provided with mounting hole.
As further improvement of the utility model, described flange is provided with brake wheel and coordinates boss.Described connection for transmission circle is provided with at least one.
As further improvement of the utility model, described axis body hardness is HRC26-29, and described axis body surface is provided with hardened layer, and the thickness of described hardened layer is the 10-20% of axis body diameter of section.Described mounting hole is symmetrical arranged, the distance between described symmetrically arranged mounting hole and tire suitable.
The utility model compared with prior art, has the following advantages.
(1) the utility model has Stability Analysis of Structures and the advantage of use safety.Owing to axis body being provided with successively flange, the first oil sealing coordinates platform, bearing fit platform, the second oil sealing coordinates platform, connection for transmission circle and spline body, and reasonable in design, assembling are simple, use safety and integral installation system stability.Because the diameter of section of the first oil sealing cooperation platform, bearing fit platform, the second oil sealing cooperation platform, connection for transmission circle reduces successively, described flange is provided with mounting hole, ensures further to install to stablize, and minimizing manufacturing expense, be suitable for industrialized production.
(2) coordinate boss because flange is provided with brake wheel, ensure further to install and stablize.Because connection for transmission circle is provided with at least one, according to the actual conditions of installing, can suitably increase connection for transmission circle.
(3) because axis body hardness is HRC26-29, described axis body surface is provided with hardened layer, and the thickness of described hardened layer is the 10-20% of axis body diameter of section, ensures that service life reduces expenditure.Because mounting hole is symmetrical arranged, the distance between described symmetrically arranged mounting hole and tire suitable, ensure the stability of overall installation system.
Accompanying drawing explanation
Fig. 1 is the structural representation of light bus rear axle shaft of the present utility model.
In figure: 1-flange, 2-axis body, 3-spline body, 4-first oil sealing coordinates platform, 5-bearing fit platform, and 6-second oil sealing coordinates platform, 7-connection for transmission circle, 8-mounting hole, and 9-brake wheel coordinates boss.
Detailed description of the invention
Below in conjunction with drawings and Examples, explanation is further explained to the utility model.
As shown in Figure 1, a kind of light bus rear axle shaft, comprise flange 1, axis body 2 and spline body 3, axis body 2 being provided with successively flange 1, first oil sealing coordinates platform 4, bearing fit platform 5, second oil sealing to coordinate platform 6, connection for transmission circle 7 and spline body 3, first oil sealing coordinates platform 4, bearing fit platform 5, second oil sealing to coordinate platform 6, the diameter of section of connection for transmission circle 7 reduces successively, and flange 1 is provided with mounting hole 8.Flange 1 is provided with brake wheel and coordinates boss 9.Connection for transmission circle 7 is provided with at least one.Axis body 2 hardness is HRC26-29, and axis body 2 surface is provided with hardened layer, and the thickness of hardened layer is the 10-20% of axis body 2 diameter of section.Mounting hole 8 is symmetrical arranged, the distance between symmetrically arranged mounting hole 8 and tire suitable.
Foregoing is example of the present utility model and explanation; but do not mean that the obtainable advantage of the utility model is so limited, may to wherein one or more of the advantage realized in the simple transformation of structure and/or some embodiments all in the protection domain of the application in every the utility model practice process.
