Problems solved by technology

In order to ensure the safety, energy saving and environmental protection of vehicles, to enable vehicles to be maintained and repaired in time during use, and to restore vehicle performance, vehicle intelligent detection and diagnosis technology and equipment have become an indispensable and important part. With the development of the automobile industry There is a wide range of market demands for development, but the traditional domestic and foreign automobile inspection lines cannot conduct comprehensive and rapid automatic inspections on the comprehensive performance of automobiles, and some inspection items still use manual inspections, resulting in the inability to conduct comprehensive, sufficient and accurate inspections of related vehicles in a timely manner. Testing, the country has promulgated new national standards (GB18565-2001, GB / T18344-2001) for the technical status and testing status of vehicles in use

Embodiment 1

[0048] Embodiment 1, please refer to Figure 6 Shown:

[0049] The first station is equipped with an exhaust gas analyzer 77, a smoke meter 78, an automobile chassis dynamometer 65, and a wheel speed testing platform 60. First, the exhaust gas analyzer 77 for gasoline vehicles (the smoke meter 78 for diesel vehicles) detects the exhaust emission performance. Then, use the wheel speed detection platform 60 and the automobile chassis dynamometer 65 to test the output power of the driving wheels of the automobile, the sliding ability, the transmission efficiency of the power train, check and correct the vehicle speed-odometer and indirectly test the power of the automobile engine.

[0050] The second station is provided with an automobile sideslip inspection platform 40, an automobile chassis loose gap detection platform 43, a wheel angle detector 46, and a steering wheel manipulation force and angle detector 47. The vehicle side slip test bench 40 is used to detect the side sl...

Embodiment 2

[0054] Embodiment two, please refer to Figure 7 Shown:

[0055] The first station is provided with an exhaust gas analyzer 77 , a smoke meter 78 , and a wheel speed detection platform 60 . First, the exhaust gas analyzer 77 for gasoline vehicles (the smoke meter 78 for diesel vehicles) detects the exhaust emission performance of the vehicle. Then, detect the vehicle speed-odometer accuracy under the state of motion with the wheel speed detection platform 60.

[0056] The second station is provided with an automobile sideslip inspection platform 40, manual detection under the ditch car, a light detector 54, a sound level meter 57, an automobile pedal stroke and pedal force detector 50, and a steering wheel manipulation force and rotation angle detector 47. The vehicle side slip test bench 40 detects the side slip of the steering wheel. Under the trench car, manually detect the gaps of the wheels, vertical shafts, suspension hinges, and steering mechanism connections on the ...

Embodiment 3

[0059] Embodiment three, please refer to Figure 8 Shown:

[0060] The first station is provided with an exhaust gas analyzer 77 , a smoke meter 78 , an automobile chassis dynamometer 65 , and a wheel speed detection platform 60 . First, the exhaust gas analyzer 77 for gasoline vehicles (the smoke meter 78 for diesel vehicles) detects the exhaust emission performance of the vehicle. Then, use the wheel speed detection platform 60 and the automobile chassis dynamometer 65 to test the output power of the driving wheels of the automobile, the sliding ability, the transmission efficiency of the power train, check and correct the vehicle speed-odometer and indirectly test the power of the automobile engine.

[0061] The second station is provided with an automobile sideslip inspection platform 40, an automobile chassis loose gap detection platform 43, a wheel angle detector 46, a light detector 54, a sound level meter 57 and a steering wheel manipulation force and rotation angle d...
