Abstract
The invention discloses a bench test device for a drive axle assembly with an axle load, and the device comprises a drive mechanism connected with the input end of a to-be-detected drive axle, a loading mechanism which is connected with two output ends of the to-be-detected drive axle, and an axle case loading mechanism for applying a load to the case of the to-be-detected drive axle. The axle case loading mechanism comprises a press plate assembly which is used for compressing the case of the to-be-detected drive axle, an axle case loading apparatus which is used for applying a load to the press plate assembly, and a sensor which is used for detecting the applied load of the axle case loading apparatus. According to the invention, the device irons out the defects of a bench test carried by a bench test device for a drive axle assembly under the no-load condition in the prior art. The device can simulate the operation condition of a real car with the drive axle with the load, and achieves a purpose of checking the drive axle and the accessories thereof.
Description
Technical field
The present invention relates to a kind of driving axis bench test device.
Background technology
At present, driving axis are generally fixed on drive axle on ferrum floor in spring block position, are not inconsistent with real vehicle state when bench test is installed by support.
At present, driving axis bench test device is all to carry out bench test in the case of no axle load.But drive axle is band axle load during actual use, this causes axle housing produce a certain degree of deformation, and the auxiliary equipment on axle housing can all be affected.Therefore, current driving axis bench test device cannot examine the drive axle with axle load and its auxiliary equipment.
The content of the invention
For the shortcoming for carrying out bench test in the case of overcoming driving axis bench test device in prior art and not having axle load, the present invention is to provide for a kind of band axle load driving axis bench test device, it can simulate the operating condition of the real vehicle with axle load of drive axle, reach the purpose of examination drive axle and its auxiliary equipment.
The technical scheme is that：The load maintainer that is respectively connected with including the drive mechanism and two outfan of drive axle to be detected that are connected with drive axle input to be detected, for the axle housing load maintainer to Drive axle housing imposed load to be detected；Axle housing load maintainer is included for compressing the Anchor plate kit of Drive axle housing to be detected, for the axle housing charger for Anchor plate kit imposed load, for detecting the sensor of axle housing charger imposed load.
The Anchor plate kit includes pressing plate positioned at Drive axle housing top to be detected, positioned at the guiding crossbeam of Drive axle housing bottom to be detected, connect pressing plate and be oriented to the screw rod of crossbeam, be oriented to crossbeam slip cap loaded on support.
The axle housing charger upper end Jing sensors are contacted with pedestal upper end, and axle housing charger lower end is contacted with pressing plate.
The support is two, respectively at putting drive axle plates spring abutment position to be detected.
The support is portal frame.
The drive mechanism includes driving means, input pickup and input shaft.
The load maintainer includes charger, output transducer, power transmission shaft, the bearing block for connecting power transmission shaft and drive axle to be detected.
The bearing block is fixed on ground.
Due to drive axle sample Jing pressing plates and screw rod in the present invention, it is fixed on guiding crossbeam in spring block position, and is oriented to crossbeam and can only move up and down along portal frame, left and right outfan is directly connected to and is fixed on ferrum floor with bearing block, therefore, reach the installment state as real vehicle.Due to by portal frame, sensor and charger, axle load being applied to axle housing, therefore, it can carry out the bench test with axle load state, reach the purpose of examination driving axis and its auxiliary equipment in the case of with axle load.
In the present invention, the mounting means of drive axle is the mounting means for simulating real vehicle, overcome the shortcoming that spring block position is fixed and real vehicle state is not inconsistent in existing mounting means, the version of the present invention can be simulated real vehicle and apply car load rated load on Drive axle housing and be tested.Present configuration is simple, can apply axle load, the drive axle that can be examined under axle load and its auxiliary equipment to drive axle.
Description of the drawings
