Abstract

The invention relates to a transport engineering and can be used in resource and functional tests of vehicles. The purpose of the invention is to expand the functionality. The rear drive wheels 5 of the test vehicle 6 are mounted on the rear endless belts 4, kinematically connected to the semi-axes of the additional test vehicle 8. The front drive wheels 18 of the test vehicle 6 are mounted on the front endless belts 17, kinematically connected by an adjustable transmission with the additional power shaft of the test vehicle 8. When the driving and brake modes alternate between the engines of both vehicles, their units are loaded with torque. 2 Il. cl

The invention relates to a transport engineering and can be used in resource and functional tests of vehicles.

The purpose of the invention is to expand the functionality.

FIG. 1 shows a stand, a general view of FIG. 2 - the same plan.

On base 1, racks 2 are fixed, on which, by means of rolling bearings, tensioning wheels 3 are covered, covered by endless belts 4 for placing driving wheels 5 of both types of rear axle drive of test vehicle 6 to reduce deflection under the upper branches of endless belts 4. plates 7. Additional test vehicle 8 is placed on the uprights 9 and 10, mounted on the base 1. On the semi-axes x 11 and 12 of the additional test vehicle 8 are fixed sprockets 1 3 and 14 meshed with the links of the endless belts 4. On the base 1, racks 15 are also fixed, on which, by means of rolling bearings, tensioning wheels 1b are mounted, covered by additional endless belts 17 for accommodating driving wheels 18 on both sides of the forward driving axle of the test transport the means 6, To decrease the deflection, the base plates 19 are fixed under the upper branches of the endless belts 17. The drive sprockets 20, meshed with the links of the endless belts 17, are rotatably mounted on racks (not shown), fixed on the base 1, and kinematically connected to the shaft 21 of the additional power of the test

the vehicle 8 by means of the 45 stand functionality, adjustable gear, including gear box 22, cardan gear 23 and gear box 24. To simulate the effect of road irregularities on the endless belts 4 and 17, the obstacles 25. are fixed to the base 1 holding device 26.

The stand works as follows.

When the engine of the test vehicle 6 is operating in the driving mode, the endless belts 4 and 17 are driven from the driving wheels 5 and 18. The opposite puppy is from endless ribbons 4 and 17 through 55

the means of the drive sprockets 13 and 20, the gearbox 22, the driveline, the gear 23 and the gearbox 24 are transmitted to the semi-axles 11 and 12 and to the power take-off shaft 21 of the additional test vehicle C. loading the nodes of both test vehicles 6 and 8 with torque. The obstacles 25, the passage under the wheels 5 and 18, mimic the impact of road irregularities.

During the operation of the engine of the additional test vehicle 8 in the driving mode, the endless belts 4 are driven from the leading sprockets 13 and 14, and the additional endless belts 17 from the output shaft 21. It is transmitted to the driving wheels 5 and 18. At the same time, the engine of the test vehicle 6 operates in the braking mode, loading the nodes of both tested vehicles 6 and 8 cool torque. With the help of boxes 22 and 24 gears, the mismatch of the angular velocities of rotation of the driving wheels 5 and 18 is achieved, which provides

reproduction of the process of switching on and off the drive of the front drive axle of the test vehicle 6.

Thus, in the proposed stand, the front drive axle drive of the vehicle 6 and the power take-off shaft of the additional vehicle 8 are loaded, which expands
