Description

Variation rigidity virtual automobile body clamp suspension testing stand
Technical field
The present invention relates to a kind of automobile 1/4th suspension testing stand, a kind of suspension testing stand moved in view of body stiffness and sprung mass.
Background technology
In order to improve product development speed, it is achieved parts factory and main engine plants' synchronous development, it is desirable to have effect ground improves the test level of parts.Existing suspension testing stand focuses mostly in suspension system closed test, body movement and the body stiffness impact on suspension property during design aspect have ignored real train test, how suspension junction point is rigidly fixed with testing stand base plate, truth during this uses with suspension is not inconsistent, thus causes the error that suspension tests.In order to solve this contradiction, but needing to design the suspension testing stand of the stressing conditions during a kind of true simulated suspension uses, this testing stand clamp considers body stiffness and the motion of sprung mass.
Summary of the invention
Present invention aims to the defect of existing suspension testing stand, a kind of variation rigidity virtual automobile body clamp suspension testing stand that can simulate body stiffness and sprung mass motion conditions is provided, this testing stand clamp has in flexibility and process of the test and can float, so that proving ground test is more reasonably simulated in suspension bench test.
The present invention solves above-mentioned technical problem and be the technical scheme is that a kind of variation rigidity virtual automobile body clamp suspension testing stand, including T-slot base plate, slide-and-guide post, sliding bearing and plain bearing housing, virtual body component, suspension and vehicle wheel component, actuating vibration table, it is characterized in: slide-and-guide post and actuating vibration table are installed on the two ends of T-slot base plate, and adjustable distance is connected between slide-and-guide post and actuating vibration table with T-slot base plate, suspension and vehicle wheel component are placed on actuating vibration table, and be connected with virtual body component, virtual body component is installed on slide-and-guide post by sliding bearing and plain bearing housing;Virtual body component includes connecting gripper shoe, spring bearer plate, spring, U-type groove angular adjustment frame, the virtual vehicle body of variation rigidity, control arm connector, variation rigidity virtual vehicle body lower end is fixing with suspension and vehicle wheel component to be connected, side is connected with U-type groove angular adjustment frame angle adjustable, it is connected spring between U-type groove angular adjustment frame and spring bearer plate, spring bearer plate rear end face be connected the adjustable connection in gripper shoe vertical position, connection gripper shoe is fixing with sliding bearing and plain bearing housing to be connected, connect the adjustable connection in gripper shoe lower end side vertical position control arm connector, control arm connector is connected with suspension and vehicle wheel component.
Connect gripper shoe side upper and lower end and be respectively provided with regulation spring bearer plate and the vertical T-slot of control arm connector vertical position.Connect gripper shoe lower end and connect balancing weight by bolt and nut.
The invention have the advantages that:
The present invention gathers multi-function in integral whole.By simulating the body stiffness of different stage, suspension bench test is made more to fit proving ground test result.The suspension testing stand of the application present invention is applicable to carry out the performance test of the independent suspension such as Multi-link suspension system, McPherson strut system;Coordinate different loading systems, apply the testing stand of this fixture can meet actual condition test and intend power regime test.This testing stand is applicable to suspension system early development test.The match test of suspension and vehicle body match test and amortisseur and spring can be realized after determining body stiffness.
Accompanying drawing explanation
Fig. 1 is the structural representation of automobile 1/4th suspension testing stand of the present invention.
Detailed description of the invention
The invention will be further described with embodiment below in conjunction with the accompanying drawings.
As it is shown in figure 1, a kind of variation rigidity virtual automobile body clamp suspension testing stand, including T-slot base plate 1, slide-and-guide post 2, sliding bearing and plain bearing housing 3, virtual body component, suspension and vehicle wheel component 9, actuating vibration table 11.
1) slide-and-guide post 2 and actuating vibration table 11 are installed on the two ends of T-slot base plate 1, fix with T-bolt, adjust suspension and the installation dimension of vehicle wheel component 9 by changing the distance between slide-and-guide post 2 and actuating vibration table 11.Suspension and vehicle wheel component 9 being placed on actuating vibration table 11, and be connected with virtual body component, virtual body component is installed on slide-and-guide post 2 by sliding bearing and plain bearing housing 3.
2) virtual body component includes connecting gripper shoe 4, spring bearer plate 5, spring 6, U-type groove angular adjustment frame 7, the virtual vehicle body of variation rigidity 8, control arm connector 10 and balancing weight.Variation rigidity virtual vehicle body 8 lower end is fixed with suspension and vehicle wheel component 9, side is connected with U-type groove angular adjustment frame 7 by screw-nut, adjusts suspension and the setting angle of vehicle wheel component 9 by changing the setting angle between the virtual vehicle body of variation rigidity 8 and U-type groove angular adjustment frame 7;
3) spring 6 is connected between spring bearer plate 5 and U-type groove angular adjustment frame 7.Spring bearer plate 5 rear end face be connected the adjustable connection in gripper shoe 4 vertical position, connect gripper shoe 4 to fix be connected with sliding bearing and plain bearing housing 3, connecting the adjustable connection in gripper shoe 4 lower end side vertical position control arm connector 10, control arm connector 10 is connected with suspension and vehicle wheel component 9.
