Embodiment approach

[0035] The invention relates to a detection device for out-of-roundness of truck wheels. figure 1 , the device is mainly composed of knob magnet 1, rocker bolt 2, rocker arm 3, radar lower support 4, fine-tuning bolt 5, radar bracket 6, micro lidar 7, radar upper support 8, support bolt 9, radar Bolt 10, nut 11, bearing locating bracket 12, lower bearing locating bolt 13, radar locating bracket 14, radar bracket locating bolt 15 form. By loosening the rocker arm bolt 2, moving the radar lower support 4 to a suitable position along the x direction, that is, left and right, and tightening the lower support positioning bolt 13 on the support positioning bracket 12, the positioning of the micro laser radar 7 in the x direction can be realized , the support positioning bracket 12 is connected with the radar lower support 4 and the radar upper support 8 through the lower support bolts 13 . Loosen the support bolt 9, and adjust the fine-tuning bolt 5 to realize the rotation of the r...

Abstract

The invention relates to a dynamic detection device and method for out-of-roundness of wheels of a truck based on a miniature laser radar. The device is mainly composed of knob magnets, rocker arms, radar upper and lower supporting bases, a supporting positioning bracket, a radar supporting bracket and a positioning bracket, an adjusting bolt and a nut. The micro-laser radar scans upper swing armball heads and upper rims of the wheels in real time to obtain the vertical distance between the upper swing arm ball heads and the upper rims of the wheels, the jerk value caused by bumps in the roadof the wheels is removed according to the detection principle, and the maximum radiuses of the wheels are calculated to evaluate the out-of-roundness of the wheels. The method can achieve real-time dynamic detection of the out-of-roundness of the wheels of the truck, and the device has a simple structure to facilitate installation operation. Research results have certain theoretical value and practical value and have good application and promotion prospects.

Description

technical field [0001] The invention relates to a detection device and method for a truck wheel, in particular to a detection device and method for the out-of-roundness of a truck wheel. Background technique [0002] When a large truck is overloaded for a long time or subjected to bumps, the wheels are prone to out of roundness. Larger wheel out of roundness will bring vibration and impact to the vehicle, directly affecting the sensitivity of the steering wheel. What's more serious is that the small wheel out-of-roundness will not be perceived by the driver during driving, but the out-of-roundness of the wheel may cause the risk of tire blowout, which threatens the driving safety of the car. [0003] At present, there are mainly two detection methods for wheel out-of-roundness: static detection and dynamic detection. Static detection is mainly manual measurement, the work efficiency is low, and the dynamic detection of wheel out-of-roundness cannot be performed in real time...
