The first straight line hydraulic actuation cylinder wears the first unidirectional line slideway and the track base successively, and by this first Connecting rod is mutually fixed with the bushing sleeves device, and the bushing sleeves device is fixed with the bushing mounting assembly, the bushing mounting assembly Mutually fixed with the fixture;
Also include one and be used for the second straight line hydraulic actuation cylinder, one vertical that axial force is provided for the bushing sleeves device The second unidirectional line slideway and a second connecting rod that post, one are fixed on the column, one end of the second unidirectional line slideway with Second straight line hydraulic actuation cylinder connection, the other end are connected by the second connecting rod with the bushing mounting assembly;
Also include one and be used for the 3rd linear hydraulic cylinder and one that torsion force is provided for the bushing mounting assembly Three connecting rods, the 3rd linear hydraulic cylinder is in contact by the third connecting rod with the fixture.
It is preferred that the bush test bench frame apparatus, which also includes one, reverses cylinder and a switching connector, the torsion cylinder is cut with this Change connector to be fixed on the substrate, the torsion cylinder wears the switching connector and is connected with the fixture.
On the basis of common sense in the field is met, above-mentioned each optimum condition can be combined, produce the utility model it is each compared with Good example.
Positive effect of the present utility model is:
1st, carry out axial direction, radial direction to bushing by three linear hydraulic cylinders and reverse three directions to load simultaneously, Three directions load and truer can must simulate various typical conditions simultaneously, such as medium Belgian road, long Ramp bridge, TCS (slide road Face), ABS (braking road surface) gravel road, wet and slippery road, side hole etc. lower three directions of road conditions stress, can most true simulation bushing Service condition on real vehicle.
2nd, by the design of a two-way linear slide rail, solve because bushing is planar because axially and radially simultaneously The influence of tangential force is produced during loading to linear hydraulic cylinder, so as to really simulate three-dimensional of the road surface to bushing at the trial Power, while also protecting linear hydraulic cylinder.
3rd, the reasonable outside dimension of design bushing sleeves device so that only need to be by changing the internal diameter chi of bushing sleeves device It is very little, just can cover comprising external bushing in external bushing in preceding lower control arm front and rear bushings, rear upper suspension arm, rear drag link, it is rear under The experimental rig of all bushings of front-rear axle in control arm including external bushing, torsion beam bushing, rear trailing arm bushing etc., so as to reach Most experiment demands are met with minimum experimental rig cost.
4. this bush test, which is the three axis force realized by three linear hydraulic cylinders, tests (radial direction+axial direction+torsion), but This experiment can also be converted to linear hydraulic cylinder simultaneously and hydraulic actuation cylinder is reversed while two carried out test (footpath to power To+reverse), this device has had linear hydraulic cylinder concurrently and has reversed the change over adapter of hydraulic actuation cylinder in design, during experiment Can free switching in both modes.
