Specific embodiment
The present invention is further illustrated in the following with reference to the drawings and specific embodiments.
Embodiment 1
As shown in Figure 1, a kind of automobile stabilizer bar fatigue experimental device, including 2 clamping devices, 6,2 executing agencies, 2 pieces
Support plate 3 and pedestal 1,2 clamping devices 6 are separately positioned on 2 pieces of 3 tops of support plate, 2 clamping devices 6 folder
Holding stabiliser bar 7, the executing agency is separately positioned on 7 both ends of stabiliser bar, and two pieces of support plates 3 are symmetricly set on 1 both ends of pedestal,
Support plate design its shape be it is trapezoidal, trapezoidal bottom is mounted on base plate 2, increase the length that contacts with base plate 2 of bottom,
Stability when testing machine operation is improved, material is saved.The design of supporting device is using the thought by multiple part combinations, in this way
It saves material and also facilitates processing, while being also convenient for carrying.
Clamping device 6 includes 2 V-type locating pieces, and 2 V-type locating pieces are upper locating piece and lower locating piece, institute respectively
It states 2 V-type locating pieces to be horizontally set in support plate 3, lower locating piece is bolted with support plate 3, and the upper locating piece is under
Locating piece is opposite to be bolted.In order to detect experimental rig to the stabiliser bar 7 of different model, select vee-block fixed
Position.The V-type locating piece is wider with range.Though positioning datum whether by processing, whether complete cylindrical surface or
Local arc surface, all can be used vee-block；V locating piece is good to neutrality, and the positioning datum axis of workpiece can be made to be centered in vee-block two
On the symmetrical plane on a inclined-plane, will not shift in the lateral direction, and easy for installation " drawing executing agency includes push rod 5
With hydraulic cylinder 4, the push rod 5 is separately connected stabiliser bar 7 and hydraulic cylinder 4, and the push rod 5 uses U-shaped connector with stabiliser bar 7.
Executing agency includes push rod 5 and hydraulic cylinder 4, and the push rod 5 is separately connected stabiliser bar 7 and hydraulic cylinder 4, the push rod
5 use U-shaped connector with stabiliser bar 7.The working condition of 7 fatigue test of stabiliser bar is past on 7 end vertical direction of stabiliser bar
Multiple movement, predominantly detects the torsional strength of the bending strength and shaft at lever arm, and whether the times of fatigue of verifying stabiliser bar 7 closes
Lattice, for the direction of support force and driving force, there is no specific requirements, due to 4 small volume of hydraulic cylinder, so designing a kind of new
Modes of emplacement can satisfy test requirements document so that is, by the just vertical placement of hydraulic cylinder 4, and effectively reduce land occupation sky ask.
Stabiliser bar 7 is horizontal positioned, using at 7 shaft both ends of stabiliser bar as the gripping point of bushing, guarantees the stabilization of stabiliser bar 7 in test
Property, trapezoidal support plate 3 is installed under bite, further enhances the stability of system.Common fatigue tester is in stabiliser bar 7
End point is using unilateral earrings connection type, and connection pin shaft will receive unilateral shear stress, and contact area is small, tired real
During testing, pin shaft is also easy to produce fatigue fracture, causes the termination of test, so 4 end of hydraulic cylinder is designed as U-shaped connection, when
7 end of stabiliser bar be less than U-shaped connector be loaded width when, end can be placed among U-shaped head, cut the unilateral side of pin shaft
Shear force becomes beautiful side stress simultaneously；When 7 end of stabiliser bar be greater than U-shaped connector be loaded width when, end can be placed in U
The side of type head increases the contact area of pin shaft, ensure that the service life of pin shaft, design connection head shapes, bottom is fixed
Mode is hingedly fixed using ears flange, and the power that hydraulic cylinder 4 is subject to vertically effectively can be transmitted to pedestal 1 by this connection type
On.When stabiliser bar 7 is when carrying out fatigue test, lever arm knee generates rigid deformation, and 4 push rod 5 of hydraulic cylinder is by horizontal direction
On power, so that hydraulic cylinder 4 is generated micro-displacement in the horizontal direction；It adopts to be hinged and can effectively solve 4 level of hydraulic cylinder
The influence to fatigue test is swung, move hydraulic cylinder 4 can freely in the horizontal direction.
Long strip footing plate 2 is additionally provided on pedestal 1,2 upper surface of the base plate dress has T-slot, the basis
Hydraulic cylinder 4 is placed on plate 2.
The description and the appended drawings of the invention be considered as it is illustrative and not restrictive, on the basis of the present invention, ability
According to disclosed technology contents, some of technical characteristics can be made field technique personnel by not needing creative labor
Some replacements and deformation, are within the scope of the invention.
