Abstract

The invention discloses a pavement simulation detector. The pavement simulation detector comprises a pavement simulator used for simulating the running state of wheels of the warehouse logistics vehicle, an auxiliary torque driving device used for transmitting torque to the pavement simulator, a speed measuring device used for measuring the rotating speed of the pavement simulator and a controllerused for controlling the whole testing device to operate. The pavement simulator, the auxiliary torque driving device and the speed measuring device are all mounted on a mounting surface or lifting equipment at the same horizontal height; the torque input end and the torque output end of the pavement simulator are respectively connected with the auxiliary torque driving device and the speed measuring device; signal connection ports of the pavement simulator, the auxiliary torque driving device and the speed measuring device are electrically connected with corresponding signal connection portsof the controller respectively. The pavement simulation detector has the advantages that different road conditions including whether raining happens or not and different road materials can be simulated, and the real road holding force of the to-be-tested wheel under different conditions can be tested more accurately.

Description

technical field [0001] The invention relates to a road surface simulation detection machine. 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. However, in the existing road surface simulation equipment, it is impossible to simulate the situation of the real road surface, which makes subsequent research difficult. Contents of the invention [0003] In order to solve the above problems, the present invention proposes a road simulation testing machine which can simulate the real road surface and is easy to operate. [0004] A road surface simulation detection machine according to the present invention is characterized in that it includes a road surface simulator for simulating the runn...
