Abstract
The utility model provides a motor vehicle damping system modal test rack device, includes and corresponding and supply its rack of parking and be used for stationary gantry's connecting rod by test machine motor car wheel, the rack includes the bottom plate, erects the backup pad at bottom plate one end and middle part, has the guide board at the other end of bottom plate and the top welding of middle part backup pad, lies in two a backup pad middle parts welding jack on the bottom plate, a jack upper portion welding platform, be equipped with four truckles below the bottom plate. This structure is used for the in -process to motor vehicle damping system modal test, makes the experiment more be close real vehicle operating mode state, and the test result is more accurate. Simultaneously, the restriction to the place of vehicle test also significantly reduces, the security is high, and is easy and simple to handle.
Description
Technical field
This utility model is related to Automobile Measuring Techniques field, and particularly a kind of motor vehicles vibration insulating system is modal test bed rack-mounted
Put.
Background technology
In order that vehicle shock absorber system has more reasonably structure and stable dynamic characteristic, safety and driving are lifted
Comfortableness, the research to vehicle shock absorber service system mode increasingly receives publicity and attention, in early days to damper system mould
All in car load perfecting by stage, due to being limited by construction cycle and cost, damper system mode keeps away frequency usually for the control of state
Can not be effectively controlled.Therefore, for the Research on Dynamic Characteristic of vehicle shock absorber system, carry out in early stage and keep away frequency control, show
Obtain particularly important.
At present to each system mode method of testing of automobile generally using hammering method or vibrator advocate approach, for car load vibration damping
The test of device system mode mainly utilizes vibrator method gathered data, and adjusting vibration exciter and car load height are needed in process of the test,
In order that both matcheds, increased testing crew workload.Meanwhile, it is larger to guarantee stand stability quality, test people
Member needs many people to move in movable stand, takes time and effort, and vehicle is positioned over during stand using lifting machine time-consuming longer
And it is more dangerous, mortality is high, in order to improve test efficiency and safety, is badly in need of a kind of packaged type shock absorber system modal test
Stand.
Utility model content
The purpose of this utility model：A kind of motor vehicles vibration insulating system modal test bench frame apparatus are provided, with easy to operate,
Using safety, the high advantage of motility.
This utility model is achieved by the following technical solution：A kind of motor vehicles vibration insulating system is modal test bed rack-mounted
Put, including stand that is corresponding with tested vehicle wheels and parking for it and the connecting rod for fixed rack；Described
Frame includes base plate, is erected at the gripper shoe at base plate one end and middle part, the other end and the top welding of midfoot support plate in base plate
There is guided plate, two gripper shoe middle parts are located on base plate and weld a jack, the platform of jack upper weld one；In base plate
Lower section is provided with four castors.
Further：The base plate is provided with four prominent contiguous blocks with bolt hole, the connecting rod be connected
Block is bolted.
Further：Also include limiting the limited block of wheel position.
The beneficial effects of the utility model are：This utility model structure, for motor vehicles vibration insulating system modal test mistake
Cheng Zhong, motor vehicles are lifted to certain altitude, then push in car, are to vibroshock using the free the shock of a fall masterpiece of automobile
The exciting force of system, makes test closer to real vehicle work condition state, and result of the test is more accurate.Driver can directly by automobile open to
On testboard bay, it is to avoid lifting machine is used for multiple times automobile is down on stand, workload greatly reduces, simple to operate, not only carries
High efficiency, while reducing the use of main equipment, and then reduces cost；Meanwhile, the restriction to the place of vehicle testing
Also greatly reduce；Lifted using jack pair vehicle, it is safe.This device is also flexible with using, easily to operate
Advantage.
Description of the drawings
With reference to the accompanying drawings and examples the utility model is described in further detail.
Fig. 1 is horse structure schematic diagram of the present utility model；
Fig. 2 is agent structure top view of the present utility model.
Number explanation in figure：1 is stand, and 2 is connecting rod, and 3 is base plate, and 4 is gripper shoe, and 5 is guided plate, and 6 is jack,
7 is platform, and 8 is castor, and 9 is contiguous block.
Specific embodiment
It is as shown in Figure 1-2 a kind of motor vehicles vibration insulating system modal test bench frame apparatus of the present utility model, including 4
The stand 1 corresponding with wheel and the connecting rod 2 for fixed rack；The stand include base plate 3, be erected at base plate one end and
The gripper shoe 4 at middle part, in the other end of base plate and the top of midfoot support plate guided plate 5 is welded with, and two are located on base plate
A jack 6 is welded in fagging middle part, and jack upper weld one is used for the platform 7 parked for wheel；Set below base plate
There are four castors 8 with function processed of stopping, walking and static needs can be met.
Preferably：The base plate is provided with four prominent contiguous blocks 9 with bolt hole, the connecting rod and contiguous block
It is bolted.
Preferably：Also include limiting the limited block of wheel position, can be positioned on platform, parking brake release is particularly to vehicle
When vehicle carry out it is spacing, prevent car slipping phenomenon thus personnel injury, the limited block is the bonding jumper of two cuboids,
Be used in and be placed in wheel position, not the used time pack up.
Preferably：The castor can be packed up, specifically, by the screw rod being fixed on above castor, with stand therewith
The screw in fixed plate being engaged, rotates up, and makes castor be higher than base plate.
This utility model structure using method is as follows：
First, each stand is placed in into wheel of vehicle front appropriate location, four stands is connected with adapting rod, by foot
Wheel is packed up；
Then, by vehicle launch to be measured, slowly platform is reached along guided plate, is stopped, fixed wheel with limited block, carried out
Corresponding Preparatory work of experiment work, such as hangs or pastes probe work；
Finally, vehicle is pushed into platform, is exciting force using the free the shock of a fall masterpiece of automobile, recorded each parameter and compare
It is right, Analysis Mode frequency and identification of Mode Shape.
Using after this device, vehicle can voluntarily reach platform, it is not necessary to using large-scale crane gear to many to motor vehicles
Secondary slinging and falling, and not only increases efficiency, while the use cost of main equipment is reduced, meanwhile, to vehicle testing
The restriction in place also greatly reduces.
