Drum reaction lift type automobile axle load brake composite detecting bench and method

Abstract

The invention relates to a drum reaction lift type automobile axle load brake composite detecting bench and method, belongs to the field of motor vehicle detecting equipment, and particularly relates to equipment for detecting motor vehicle brake performance. The drum reaction lift type automobile axle load brake composite detecting bench comprises a movable frame (2), a fixed frame (1) and a brake force detecting device. The movable frame (2) is disposed in the fixed frame (1) in an up-down slide manner. A lifting device pushing the movable frame (2) to move up and down is disposed in the fixed frame (1). The brake force detecting device is fixed on the movable frame (2). The brake force detecting device is pushed to move up by the lifting device to allow a vehicle to be horizontally fixed, an included angle formed between the vehicle and a horizontal plane is avoided, the brake force performance is detected accurately, detecting accuracy is increased, the fixed frame transversely fixes the movable frame, the movable frame is prevented from swinging when the brake force detecting device operates, and stable and reliable operation is achieved.

Description

technical field [0001] The utility model relates to a drum reaction force lifting type automobile axle load braking compound inspection platform and a detection method, which belong to the field of motor vehicle detection equipment, and in particular relate to a detection equipment for detecting the braking performance of a motor vehicle. Background technique [0002] During the driving process of the car, its technical condition and performance will gradually deteriorate with the increase of mileage, the power performance will decrease, the economy will deteriorate, and the safety and reliability will decrease, which will seriously affect the economic benefits and transportation efficiency of the vehicle. Especially the quality of automobile braking performance is directly related to people's life safety. This requires that faults be identified and eliminated in advance. During the use of the car, making judgments on its operating conditions and taking corresponding counte...

Problems solved by technology

[0003] In the traditional sense, the automobile axle load brake composite table has a structure of installing load cells at the four corners below the brake table to detect the effect of the axle load. In this way, an inclination angle is formed with the horizontal plane. The inventor found that the inclination angle will cause errors in the detection and evaluation of the axle load and braking performance of the vehicle, so that there will be deviations in the braking data, which will bring great safety hazards to the driving of the vehicle.

Moreover, the existing braking force detection can only detect the braking performance of the vehicle when it is unloaded, but cannot detect the braking performance of the vehicle under load.
