Problems solved by technology

But what kind of pattern can be used to better improve the adaptability of the drive wheel to different road surfaces, and there are few professional equipment that can accurately detect the impact of different patterns on the drive wheel
[0004] When the wheel surface roundness of the driving wheel is not high enough, the bearing technology is not high enough, or other accidental factors, the driving wheel may be pinned when it is running, and it is difficult to detect the driving wheel at this time

Abstract

The invention discloses a driving wheel road holding force and life detection device and a and road holding force and life detection method. The detection device comprises a driving wheel unit which comprises a supporting device, a pushing device, and a driving wheel assembly; a road surface simulation unit which is arranged below the driving wheel unit and comprises a first supporting part, a second supporting part and a roller assembly; and a control unit which comprises a main controller, a driving wheel control circuit, a brake unit controller and a pushing device controller; the road holding force and service life detection method comprises the following steps: adjusting the position of the driving wheel assembly to enable the driving wheel assembly to be in close contact with the rolling surface for simulating close contact between a driving wheel and a simulated road surface; and then the road holding force and the service life are measured by adjusting the brake unit. The device has the beneficial effects that different pavement conditions can be simulated; the effects of different anti-skid patterns can be inspected; the service life of the driving wheel can be tested; when the driving wheel starts to slip can be detected; and the error-tolerant rate of the system is improved.

Description

technical field [0001] The invention relates to a driving wheel grip and life detection device and a grip and life detection method. Background technique [0002] With the great development of intelligent logistics, the application of warehousing and logistics vehicles is becoming more and more extensive, and the requirements for them are also getting higher and higher. The goods need to be sent from the warehouse to the workshop often need to pass through different roads. At present, most of the driving wheel tires of storage and logistics vehicles use smooth surfaces. This type of driving wheel is easy to manufacture and has high economic efficiency; A water film is produced, and slippage occurs. [0003] The anti-skid pattern on the tire increases the friction force of the driving wheel during the load operation process, reduces the slipping phenomenon, and makes the operation stable and light. So more and more drive wheels with anti-skid patterns have been applied. Bu...
