Embodiment 1

[0053] This embodiment provides a test device for measuring the interaction force between a tire and a road surface, including a power unit, a lateral force control unit, a vertical force control unit, a tire test unit, a first shaft 5 and a side wall 6;

[0054] The power unit includes an electric motor 1-1, a second shaft 1-2, a reduction gear 1-3, a power box 1-4, a first bearing 1-5, a first pillar 1-6 and a guide groove 1-7. The motor 1-1 is connected to one end of the deceleration device 1-3 through the second shaft 1-2, and the other end of the deceleration device 1-3 is mounted on the first shaft 5. The motor 1-1, the second The shaft 1-2 and the deceleration device 1-3 are both installed in the power box 1-4. The power box 1-4 is supported by the first pillar 1-6 and the guide groove 1-7. The first pillar 1 -6 is installed in the groove body of the guide groove 1-7, so that the first pillar 1-6 slides along the axial direction of the first shaft 5 in the guide groove 1-7...

Embodiment 2

[0062] The test device of this embodiment is the device described in embodiment 1. In this embodiment, the mass of the tire is 40kg, the running speed of the tire is V=80km / h, the total length of the first shaft is 600mm, and the total length of the roller shaft is 540mm. Width L=300mm, the roller is installed in the middle of the roller shaft, the weight of the roller is 40kg, and the weight of the heavy object in the vertical force control unit 3 container is 60kg. The force in each direction is measured by using a pressure sensor. The measurement result is : The normal reaction force is 1262N, the tangential reaction force is 168N, and the lateral reaction force is 89N.

Abstract

The invention discloses a test apparatus used for measuring an interaction force between a tyre and a pavement. The apparatus comprises a power unit, a side force regulation and control unit, a vertical force regulation and control unit, a tyre test unit, a first shaft and a side wall. The side wall is arranged vertically to a horizontal plane. The power unit and the tyre test unit are connected through a tyre shaft. The vertical force regulation and control unit is installed on a first shaft. One end of the side force regulation and control unit is installed on the power unit. The other end of the side force regulation and control unit is installed on the side wall. In the invention, a tangential reaction force, a lateral reaction force and a vertical reaction force between the tyre and the ground are simultaneously measured and great convenience is provided for an aspect of tyre performance research. The structure is greatly simplified and great convenience is provided for an aspect of measuring mutual active forces between different series of tyres and the ground.

Description

Technical field [0001] The invention belongs to the technical field of automobile tire experiments, and specifically relates to a test device for measuring the interaction force between the tire and the road surface. Background technique [0002] In the field of tire force analysis, the magnitude of the interaction force between the tire and the ground is important for the braking, passing, traction, safety, comfort, handling stability, and energy-saving economy of the car. Theoretical significance. [0003] However, at this stage, domestic and foreign scholars and experts also have a certain degree of research on this, and have achieved corresponding results, but the cost is relatively expensive, the structure is also relatively complex, the quality is large and mass production cannot be achieved. When measuring the interaction force between the tire and the ground, the traditional test bench can only measure a single interaction force, and the measurement conditions are relative...
