Description
Technical field
This utility model relates to field of automobile, particularly relates to a kind of Combined Loading for detecting semiaxis intensity
Testing stand.
Background technology
Semi-floating drive axle is a kind of rigid drive axle, is that one is widely used in chiasma type passenger car, light passenger-cargo carriage
And the drive axle of offroad vehicle.In car load driving process, wheel is primarily subjected to following both sides load: due to surface roughness
The shock loading introduced on tyre contact patch；Due to Vehicular turn, accelerate, brake at tire earth point introduce inertia carry
Lotus.Semifloating axle shaft is also subjected to taking turns from the vertical impact load on road surface with Vehicular turn, acceleration in car load driving process
The inertial load introduced at tire earth point.Semifloating axle shaft dish portion (bearing is to connecting Pan Chu) is except bearing the torsion in driving process
Vertical impact load and lateral duction load is still suffered from outside square.According to tired for semiaxis in automobile industry standard QC/T293
The regulation of labor test load: the moment of flexure being subject to by half-and-half bearing is converted to moment of torsion, semiaxis only is applied to make a concerted effort by semiaxis torsional fatigue test
Square, it is impossible to checking Half axle disc portion fatigue life, and the life-span in Half axle disc portion is directly connected to car load driving safety, therefore semi-floating
The checking of Half axle disc portion fatigue life is most important, needs to study a kind of testing stand for detecting Half axle disc portion fatigue strength.
Utility model content
For overcoming existing semiaxis torsional fatigue test cannot detect the deficiencies such as Half axle disc portion fatigue strength, this utility model institute
Solve the technical problem that and be: a kind of bracket loading test platform being exclusively used in detection semifloating axle shaft dish portion fatigue strength is provided.
This utility model solves its technical problem the technical scheme is that semiaxis combined loading test platform, including flower
Key support, bearing bracket and twisting fixture, described spline support is for supporting the splined end of semiaxis, and the support of bearing is used for supporting
The Half axle disc end of semiaxis, twisting fixture is arranged in Half axle disc, and described twisting fixture is provided with vertical actuator straight down
And the horizontal actuator parallel with semiaxis.
Further, described spline support is provided with the spline gear fixture splined end for the semiaxis that is fixedly clamped.
Further, described spline gear fixture is provided with torsion sensor.
Further, twisting fixture be provided with adjustment track, described vertical actuator and horizontal actuator can adjust
Slide on track.
The beneficial effects of the utility model are: by arranging spline support and bearing bracket for supporting semiaxis, then
Semiaxis is installed twisting fixture, and utilizes the vertical actuator on twisting fixture and horizontal actuator that Half axle disc is executed
Pressure, thus detect the fatigue strength in Half axle disc portion, this apparatus structure is simple, manufactures easy to use, can quick and precisely detect half
The fatigue strength in reel portion.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
Figure is labeled as, 1-spline support, 2-bearing bracket, 3-twisting fixture, 4-semiaxis, the vertical actuator of 5-, 6-
Laterally actuator, 7-spline gear fixture, 8-adjusts track.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further illustrated.
As it is shown in figure 1, this utility model includes spline support 1, bearing bracket 2 and twisting fixture 3, described spline support
1 for supporting the splined end of semiaxis 4, and the support of bearing 2 is for supporting the Half axle disc end of semiaxis 4, and twisting fixture 3 is arranged on Half axle disc
On, described twisting fixture 3 is provided with vertical actuator 5 straight down and the horizontal actuator 6 parallel with semiaxis 4.This practicality
Novel using method is: first the splined end of semiaxis 4 is penetrated at the bearing on bearing bracket 2, is inserted into spline and props up
On frame 1 and be fixed, then twisting fixture 3 is installed in the Half axle disc of semiaxis 4, laterally by vertical actuator 5 and finally
Actuator 6 is installed on twisting fixture 3, during test, is loaded twisting fixture 3 by vertical actuator 5 and horizontal actuator 6,
Thus detect the fatigue strength in Half axle disc portion.
Described spline support 1 is provided with the spline gear fixture 7 splined end for the semiaxis 4 that is fixedly clamped.Spline gear presss from both sides
Tool 7 can be suitably used for the spline of different size, clamps and dismantle all very convenient, and can clamp the splined end of semiaxis 4 firmly, anti-
Only semiaxis 4 rotates and axial float.
Described spline gear fixture 7 is provided with torsion sensor.Torsion sensor can be turned round with semiaxis during monitoring test
Turn the situation of change of fatigue test moment of torsion, in order to the comprehensive fatigue strength analyzing semiaxis.
Wheel hub corresponding to different semiaxis 4 is not of uniform size, bears lateral load to enable preferably to simulate wheel
Time the Half axle disc portion bending load situation born, described twisting fixture 3 is provided with adjustment track, described vertical actuator 5 He
Laterally actuator 6 can be slided on track 8 adjusting, and is adjusting on track 8 by adjusting vertical actuator 5 and horizontal actuator 6
Position simulate the stress point of tire, the measurement of this testing stand made is more accurate, and can be suitably used for the semiaxis of different size.
This utility model simple in construction, can detect the fatigue strength in Half axle disc portion quickly and easily, analyzes semiaxis
In the service life in dish portion, provide certain technical guarantee to safety in production, there is good practicality and application prospect.
