Side plate 3 is equipped with anti-scraping pulley 6 close to the part at two ends, and anti-scraping pulley 6 is made up of bearing and axle, and its object is to prevent
Scratched in process of the test between wheel and outer panel 3.The height of directing plate 7 should be equal to the top of the installment state of connecting rod 4
Edge.In use, directing plate 3 is placed in the two ends of interior outer panel 3 parallel to roller, in order to make the smooth row of vehicle
Sail between two rollers；It is connected interior plate 2 and outer panel 3 using connecting rod 4, while interior plate 2 and outer panel 3 play branch
Support the effect of drum assembly 1.Two spring self-lock formula lock pin components 5 being fixed on outer panel 3 are respectively with being fixed on interior outside
Drum assembly 1 between plate is corresponded, and prevents that scratching pulley 6 plays a part of protection test device and vehicle tyre.Directing plate 7
For guiding vehicle smoothly to travel between two rollers.In use, the utility model is placed in level road or straight ramp,
Lock pin stretches out lock pin shell and is caught in the cylinder wall end notches of roller, drum assembly 1 is kept locking.Vehicle passes through guiding
Plate 7 is travelled to the top of drum assembly 1, gently steps on braking, vehicle is driven between two drum assemblies 1.Lockpin sleeve is extracted simultaneously outward
It is rotated by 90 °, pin is directed at the end shallow ridges groove location of lock pin shell, and the lockpin sleeve that comes up, effect of the lock pin in spring
It is lower to left movement, until pin snaps into lock pin outer casing end shallow ridges trench bottom, now, spring is in compressive state, and lock pin is by card
In lock pin enclosure, drum assembly is free to rotate, and the wheel of vehicle being on the utility model, which is realized, to skid, and successfully simulates
On cross-country road vehicle some lose the operating mode of earth-grasping force；Prevent that guarantor can be played in wheel-slip migration process by scratching pulley 6
Protect the effect of the utility model and wheel.By cover more it is of the present utility model use cooperatively, can simulate under various road conditions, it is single
Or multiple wheels lose the operating mode of earth-grasping force, so as to weigh the cross-country ability of vehicle.After off-test, lockpin sleeve is pulled out outward
Go out and be rotated by 90 °, pin is directed at lock pin outer casing end zanjon groove location, and the lockpin sleeve that comes up.Now, spring is in
Impaction state, but the outer end in contact of lock pin left part and cylinder wall and be limited and can not eject.Vehicle is travelled, wheel rolling band
Dynamic drum assembly 1 is rotated, and when roller turns to cylinder wall notch alignment lock pin, lock pin is ejected to the left under the pressure of the spring,
Cylinder wall gap position is caught in, then roller locking, vehicle regains earth-grasping force, smoothly can be rolled away from from the utility model.
As shown in Fig. 2 drum assembly is made up of roller 8, bearing 9, central shaft 10 and axle sleeve 11, bearing 9 and roller 8 with
And central shaft 10 is interference fit；The barrel of roller 8 is having an opening 20 close to outer panel one end, is needing locking roller
When 8, spring self-lock formula lock pin component is placed in automatic pre-locking position, when the opening 20 of roller 8 is turned at lock pin, lock pin
Automatic spring, realizes the locking of roller.
As shown in figure 3, spring self-lock formula lock pin component includes lock pin 12, lock pin shell 13, spring 14, lock pin locking nut
15th, pin 16 and lockpin sleeve 17, by its close fit, realize locking and the release of roller.The smaller diameter end of lock pin 12 is led to
Cross pin 16 to be connected with lockpin sleeve 17, lock pin shell 13 is provided with two directions in the smaller diameter end of lock pin 12 and is mutually perpendicular to depth difference
Groove；When pin 16 turns to 19 position of shallow trench, pin 16 is locked out, so that locking lock pin 12, roller is in freely
State；When pin 16 is located at 18 position of deep trench, spring 14 is in compressive state, and the position of roller wall opening 20 turns to lock pin
During 12 position, lock pin 12 insertion cylinder wall opening 20, roller locking under the thrust effect of spring 14；Spring self-lock formula lock pin
Component is connected by the screw thread on lock pin shell 13 with outer panel, and the length that lock pin 12 is stretched into passes through the lock on lock pin shell 13
Tight nut 15 is adjusted.
As shown in figure 4, lockpin sleeve 17 is extracted and is rotated by 90 ° outward, make the end of the alignment lock pin of pin 16 shell 13 shallow
Grooved position and the lockpin sleeve that comes up, lock pin 12 is under action from the spring 14 to left movement, until pin 16 is snapped into outside lock pin
The end shallow ridges trench bottom of shell 13, now, spring 14 are in compressive state, and lock pin 12 is stuck in inside lock pin shell 13, roller group
Part is free to rotate, is in wheel of vehicle on the utility model and realizes and skids, successfully simulate on cross-country road vehicle some
Lose the operating mode of earth-grasping force；Prevent that the work of protection test device and wheel can be played in wheel-slip migration process by scratching pulley
With.By cover more it is of the present utility model use cooperatively, can simulate under various road conditions, single or multiple wheels lose earth-grasping force
Operating mode, so as to weigh the cross-country ability of vehicle.
As shown in figure 5, after off-test, lockpin sleeve 17 is extracted and is rotated by 90 ° outward, pin 16 is set to be directed at lock pin
The end zanjon groove location of shell 13, and the lockpin sleeve 17 that comes up, now, spring 14 are in impaction state, but the left end of lock pin 12
The outer end in contact of portion and cylinder wall is simultaneously limited and can not ejected.Vehicle is travelled, and wheel rolling drives drum assembly to rotate, and works as rolling
When cylinder turns to cylinder wall notch alignment lock pin 12, lock pin 12 is ejected to the left under the pressure of spring 14, is caught in cylinder wall breach
Position, then roller locking, vehicle regains earth-grasping force, smoothly can rolled away from from the utility model.
