Device for accurately measuring vehicle wheel slip ratio

The invention discloses a device for accurately measuring vehicle wheel slip ratio with an aim to overcome the shortcomings that an existing wheel speed measuring device and a vehicle speed sensor cannot accurately measure vehicle wheel speed and wheel hub speed and solve the problem about the lack of a device for directly measuring the vehicle wheel slip ratio. The device comprises a telescopic adjusting mechanism (1), a sensor acquisition processing unit (2), a sensor rotating component (3) and a wheel connecting component (4). The sensor rotating component (3) comprises a rotating shaft (14) and a connecting disc (15); the rotating shaft (14) and the bottom surface of the connecting disc (15) are integrally connected, the lower end of the rotating shaft (14) is rotatably connected with the bottom plate of a device shell (19) in the sensor acquisition processing unit (2), the wheel connecting component (4) is connectively mounted on the connecting disc (15) in a threaded manner, and the right end of a screw D (13) in the telescopic adjusting mechanism (1) is connected with the left side of the device shell (19) in the sensor acquisition processing unit (2) in a welded manner.
