Existing trailer during reasons cannot the meet complete vehicle test such as trailer is longer because the needs of the on-the-ground test of part, leading to
Having often occurred semitrailer, there are following drawbacks in tractor complete vehicle test：1, tractor vehicle on-the-ground test include coefficient of intensification compared with
The experiments such as big distortion road travels, Belgian road travels, washboard road traveling, 11 rice barn column semitrailers, 13 rice bin formula semi-mounteds
The semitrailers such as vehicle can not be by the distortion road in complete vehicle test place, and there is also peaces at Belgian road and washboard pavement for traveling
Full hidden danger.2, higher to axle load required precision in complete vehicle test, and load can move during the test after common semitrailer load
The dynamic precision that can not ensure axle load.3, common semitrailer adjustment axle load is more difficult.
Invention content
The purpose of this utility model is that cannot meet present in tractor complete vehicle test for existing semitrailer whole
During vehicle experiment the problems such as the on-the-ground test demand of part, a kind of trailer for tractor vehicle on-the-ground test is provided.
To achieve the above object, the technical solution of the utility model is：One kind being used for tractor vehicle on-the-ground test
Semitrailer, including compartment, vehicle frame, leaf spring, vehicle bridge, tire assembly, towing pin, euphroe, rope hook, taillight and side
Lamp, this semitrailer overall length is 7700mm, beam overall 2500mm, total a height of 2440mm, compartment front end cross beam both ends difference
It is provided with support leg.
It is provided with pneumatic device and electric-controlled switch above the support leg.
Be provided with two active clapboards I in the compartment, described two active clapboards I by compartment be divided into weighted areas,
Three regions in the areas Tiao Zai and testing equipment installing zone.
Multiple grooves are provided on the car side board, two active clapboards I are mounted on side plate different location
In groove.
Divided for four parts by two active clapboards II inside the areas Tiao Zai.
Two II right-angled intersections of active clapboard inside the areas Tiao Zai.
Compared with prior art, the utility model has the beneficial effects that：
1, the utility model semitrailer overall length be 7700mm, beam overall 2500mm, total a height of 2440mm, vehicle can be passed through
All Surface of Trial Pavement in on-the-ground test meet tractor complete vehicle test place passability demand.
2, it is provided with pneumatic device and electric-controlled switch above support leg in the utility model, this semitrailer can by support leg
It is individually parked with being detached from headstock.
3, two active clapboards I are provided in the utility model in compartment, compartment is divided into counterweight by two active clapboards I
Three area, the areas Tiao Zai and testing equipment installing zone regions；And two active clapboards I are as needed mounted on side plate different location
In groove.I position of active clapboard can change, and load will not big amplitude shift after ensureing compartment load while facilitating load to adjust
It is dynamic；Meet tractor vehicle on-the-ground test load demand, and with accurate adjustment vehicle axle load.
Description of the drawings
Fig. 1 is the utility model structure diagram.
Fig. 2 is the utility model vertical view.
In figure, compartment 1, support leg 2, electric-controlled switch 3, pneumatic device 4, active clapboard I 5, weighted areas 6, the areas Tiao Zai 7, examination
Test equipment installing zone 8, active clapboard II 9.
Specific implementation mode
The utility model is described in further detail below in conjunction with description of the drawings and specific implementation mode.
Referring to Fig. 1 to Fig. 2, a kind of semitrailer for tractor vehicle on-the-ground test, including compartment 1, vehicle frame, steel plate bullet
Spring, vehicle bridge, tire assembly, towing pin, euphroe, rope hook, taillight and side lamp.This semitrailer overall length is 7700mm, beam overall is
2500mm, total a height of 2440mm, i.e. this semitrailer overall dimensions are 7700mm*2500mm*2440mm, can pass through vehicle place
All Surface of Trial Pavement in experiment.
Referring to Fig. 1, the 1 front end cross beam both ends of compartment are respectively arranged with support leg 2.Further, the support
2 top of leg is provided with pneumatic device 4 and electric-controlled switch 3.Pneumatic device 5 is used to provide power to support leg 2 is flexible so that support
Leg 2 quickly and easily can shrink and stretch out, and can be detached from headstock by 2 semitrailers of support leg individually parks.
Referring to Fig. 2, it is provided with two active clapboards I 5 in the compartment 1, described two active clapboards I 5 are by compartment 1
It is divided into 8 three weighted areas 6, the areas Tiao Zai 7 and testing equipment installing zone regions；Two I 5 positions of active clapboard can change, and pass through
I 5 position of adjustment active clapboard can change 7 size of weighted areas 6 and the areas Tiao Zai, while can limit mass during the test
