Abstract
The invention relates to a rack for detecting a flexible fatigue life of an automotive half shaft and a detection method. The rack for detecting the flexible fatigue life of the automotive half shaft comprises a fixed base and a loading arm (8), wherein the fixed base comprises a base (1), an axle housing sleeve (2) and an axle housing flange head (3); foundation bolt holes are arranged on the periphery of the base (1); the centre of the base (1) is connected with the axle housing sleeve 2 in a vertical direction, the axle housing flange head (3) is connected to the upper side of the axle housing sleeve (2), and the axle housing flange head (3) is provided with a flange hole connected with a flange hole of a bearing seat (6) of a half shaft support; and a connecting end connected with a half shaft flange of the half shaft support is arranged on one end of the loading arm (8). The rack for detecting the flexible fatigue life of the automotive half shaft and the detection method, provided by the invention, can be used for simulating a test for applying a lateral acting force to the half shaft through loading a fluctuating force loaded on the loading arm when the automobile runs under an S-shaped curved road condition, detecting lateral flexible fatigue resistance of the half shaft through the test and judging the fatigue rupture of the half shaft in advance.
Description
Technical field
The invention belongs to the Performance Detection field of auto parts and components, relate to a kind of stand and detection method that detects automobile axle shaft flexible life.
Background technology
At present, the automobile axle shaft bench test has only that semiaxis is quiet turns round two kinds of strength test and semiaxis torsional fatigue life tests.The quiet radially maximum twist moment of turning round strength test detection semiaxis of semiaxis; The test of semiaxis torsional fatigue life detects radially torsional fatigue life of semiaxis; And to automobile under the S detour condition condition of going, during side direction transversal force that automobile is left and right to be produced when taking turns turning to of receiving, semiaxis receives lateral thrust power; Though and fatigue lifetime and the bench test method of country when not being defined in semiaxis and receiving lateral thrust power, lost efficacy in advance at semiaxis also slowly fatigue break of power by bending.For addressing this problem, need a kind ofly can detect the anti-lateral thrust of semiaxis stand and the detection method of fatigue lifetime.
Summary of the invention
The purpose of this invention is to provide a kind of stand and detection method that detects automobile axle shaft flexible life that can detect the tired ability of the anti-lateral thrust of semiaxis.
One of technical scheme of the present invention: it comprises fixed pedestal and loading arm, and described fixed pedestal comprises base, axle housing sleeve pipe and axle housing collar head; Be provided with anchor (bolt) hole around the base; Base is connected with the axle housing sleeve pipe in vertical direction, and axle housing sleeve pipe top is connected with the axle housing collar head, and the axle housing collar head is provided with flange hole and is connected with the flange hole of the bearing seat of semiaxis supporting; One end of loading arm is provided with the link that is connected with the semiaxis flange of semiaxis supporting.
Base is provided with the pilot hole that is connected with semiaxis, the center of pilot hole the axle housing sleeve pipe axially on.
Described base and axle housing sleeve pipe are welded to connect, and axle housing sleeve pipe and axle housing collar head are welded to connect.
Two of technical scheme of the present invention: detection method is following:
Earlier fix fixed pedestal with the anchor (bolt) hole of foot bolt through fixed pedestal;
The semiaxis supporting is put on the fixed pedestal, and an end of semiaxis is connected with the pilot hole of base earlier, through bolt bearing seat is connected with the axle housing collar head again;
Through bolt the link of loading arm is connected with semiaxis flange in the semiaxis supporting;
On the automobile rolling radius R on the loading arm, load pulsating force F;
Pulsating force F is the suffered side force of car load, and under pulsating force F effect, the bending fatigue of carrying out semiaxis detects.
The present invention has simulated automobile under the S detour condition condition of going; Through being carried in the pulsating force on the loading arm; Simulate and realize that semiaxis receives side action power and makes an experiment, detect the tired ability of the anti-lateral thrust of semiaxis, judge the semiaxis fatigue break in advance through this test.
Description of drawings
The structural representation of Fig. 1, the embodiment of the invention 1.
Embodiment
The present invention can pass through the technical scheme practical implementation, can do further description to the present invention through following embodiment, yet scope of the present invention is not limited to following embodiment.
Embodiment 1: base 1, axle housing sleeve pipe 2 and axle housing collar head 3 are fixed on through foot bolt on the base of monitor station through being welded into the fixed pedestal structure.The semiaxis supporting has semiaxis 4, back-up ring 5, bearing 7 and bearing seat 6 to be one by the semiaxis fit; Semiaxis 4, back-up ring 5, bearing 7 and bearing seat 6 are through special-purpose press-loading device, and being press-fit into place becomes the semiaxis supporting structure, need press-fit the semiaxis supporting structure when detecting at every turn.One end of semiaxis 4 is connected with the pilot hole of base 1 earlier; The fixed pedestal structure is connected with bolt with the semiaxis supporting structure; The semiaxis flange hole of semiaxis supporting structure is connected with loading arm 8 usefulness bolts, acts on the pulsating force F on the automobile rolling radius R of loading arm 8, is provided by the equipment that pulsating force is provided.Begin test after each position connects, the suffered side direction of car load calculates pulsating force F under the effect of pulsating force F, carries out the repeated bend test of semiaxis, reaches to detect semiaxis flexible life purpose.
