Description

Technical Field

[0001] The utility model relates to the technical field of vehicle detection, in particular to a vehicle performance testing device. Background Art

[0002] When the existing vehicle performance detection device measures the output power, torque, rotation speed, etc. of the vehicle driving wheels, especially when detecting heavy vehicles, since the upper surface of the detection component is basically flush with the upper surface of the detection device, it is necessary to limit the vehicle on the detection device by safety binding ropes during detection to prevent the vehicle from rushing out of the detection surface of the detection device during the detection process. However, the operating power of heavy vehicles is relatively large, and it is extremely easy to break the safety binding ropes, resulting in the vehicle rushing out of the detection surface of the detection device and causing damage to the detection device and the vehicle. Moreover, the existing vehicle performance detection device relies on a lifting bracket to lock the drum. However, during detection, the drum forms a large impact force due to a large rotational force, so it causes relatively large wear on the brake pads of the lifting bracket, and the brake pads need to be frequently repaired and replaced, which increases the use cost of the vehicle performance detection device.

[0040] The specific working principle is as follows:

[0041] When performing performance detection, drive the vehicle onto the vehicle performance detection device and park the tires at the position of the test groove. After the vehicle stops stably, start the test device. At this time, the first hydraulic device drives the first braking crossbar to move downward, and the first braking crossbar disengages from the lower surface of the detection roller. Under the action of the vehicle's own weight, the detection roller at the stressed part moves downward unevenly. The detection roller with the stress center point wraps the outer circumference of the tire of the wheel in sequence from the bottom end; start the vehicle for detection, collect data through the detection device connected to the detection roller in contact with the tire of the wheel, and transmit the vehicle performance data to the detection device controller. After the detection device controller summarizes and processes the data, it transmits the data to the designated display screen; after the detection is completed, start the first hydraulic device. The first hydraulic device pushes the first braking crossbar upward to move, so that the brake pads on the first braking crossbar are successively in contact with the detection roller at the bottom end and the detection rollers on its two sides. At the same time, the first braking crossbar and the detection roller on the brake pad are pushed upward synchronously, so that the upper outer peripheral surface of the detection roller is in contact with the brake pad on the second braking crossbar. Generate a clamping force and friction force on the detection roller through the brake pads arranged oppositely on the first braking crossbar and the second braking crossbar, so that the detection roller stops rotating and the tire of the vehicle is lifted to the upper surface of the detection groove. After the detection roller stops rotating, the vehicle safely drives off the test device.
