Embodiment 1

[0027] Embodiment 1: the approach angle of the tested car is 21°.

[0028] Adjust the connection position of the connecting sleeve 4 so that the distance between the centerline of the left and right bridge body is consistent with the wheel base of the vehicle being tested. The angle of inclination of the adjustable part of the uphill bridge body 1 is 21° through the approach bridge hinge mechanism, and the fixed base 1-12 is selected. Six (in order from left to right) connecting holes, connect the vertical support 1-6, the connecting seat 1-9 and the fixed base 1-12 through the bolt assembly, and then connect the uphill bridge body 1 through the bolt assembly The lower end of the adjustable part is connected with the third connecting hole of the fixed base 1-12. After the installation process is completed, the roller mechanism cover plate 8 can be put on to detect the climbing ability of the vehicle to be tested; the roller mechanism cover plate can be removed to test the perf...

Embodiment 2

[0029] Embodiment 2: the approach angle of the tested car is 19°.

[0030] Adjust the connecting position of the connecting sleeve 4 so that the distance between the centerline of the left and right bridge body is consistent with the wheelbase of the vehicle being tested. The inclination angle of the adjustable part of the uphill bridge body 1 is 19° through the approach bridge hinge mechanism, and the extended vertical support 1- 6. Select the fifth (from left to right) connection hole of the fixed base 1-12, connect the vertical support 1-6, the connecting base 1-9 and the fixed base 1-12 through the bolt assembly, and then The hook 1-10 of the extended plate is assembled with the hinged shaft 1-11 of the extended plate installed at the lower end of the approach bridge frame, and is connected with the third connecting hole on the fixed base 1-12 of the uphill bridge body through the inclined brace of the extended plate. The extension plate connection seat is connected with t...

Embodiment 3

[0031] Embodiment 3: the approach angle of the tested car is 16°.

[0032] Adjust the connecting position of the connecting sleeve 4 so that the distance between the centerline of the left and right bridge body is consistent with the wheelbase of the vehicle being tested. The inclination angle of the adjustable part of the uphill bridge body 1 is 16° through the approach bridge hinge mechanism, and the extended vertical support 1- 6. Select the fourth (from left to right) connecting hole of the fixed base 1-12, connect the vertical support 1-6, the connecting base 1-9 and the fixed base 1-12 through the bolt assembly, and then The hook 1-10 of the extended plate is assembled with the hinged shaft 1-11 of the extended plate mounted on the lower end of the approach bridge frame, and connected with the second connecting hole on the fixed base 1-12 of the uphill bridge body through the inclined brace of the extended plate. The extension plate connection seat is connected with the ...

Abstract

The invention relates to a test bench for automobile climbing capacity and differential lock performance. The test bench consists of an upslope bridge body, a middle bridge body and a downslope bridge body, wherein the upslope bridge body comprises a fixed part and an adjustable part; the adjustable part consists of a left approach bridge, a right approach bridge, a connecting sleeve and a lengthened board assembly; the left approach bridge comprises an approach bridge frame, a lengthened board hinged shaft, an approach bridge surface, an upright strut, an inclined strut, an outer guardrail, an inner guardrail and a connecting base; the right approach bridge and the left approach bridge are symmetrical, and a roller group mechanism is arranged between the right approach bridge and the left approach bridge; the connecting sleeve consists of two rectangular tubes with different models; and the two rectangular tubes are tightly connected through a bolt assembly piece. The test bench can test the performance of automobiles with different models by different types of connection of split type and adjustable truss structures, and prevents detection equipment from being repeatedly set.

Description

technical field [0001] The invention relates to an automobile testing platform, which is especially suitable for verifying the climbing ability and differential lock performance of automobiles, and belongs to the technical field of automobile testing equipment. Background technique [0002] The test of climbing ability and differential lock performance of off-road vehicles is a mandatory inspection item for automobile manufacturers, and it is also one of the mandatory inspection items stipulated by the state. Because the car is often affected by bad road conditions during driving, its climbing ability is an important factor in determining the passing performance of the car; Axle driving phenomenon happens from time to time. At this time, the adhesion force of the four tires is completely different. In the limit state, a pair of diagonal wheels are stuck, while the other pair of diagonal wheels are completely suspended. Under certain circumstances, the performance of the fro...
