Abstract

The invention relates to a sliding angle detection device and a detection method for tire durability, increases the sliding angle detection device, aims at road conditions of turning or nonlinear running and the like of a vehicle, and simulates detection in a state when a tire and a road surface cause a sliding angle friction. The sliding angle detection device and the detection method comprise a rack, wherein a rotary drum which is driven by a motor for simulating the road surface in running is arranged on the rack, a hydraulic pressure device is arranged at least at a station position at one side of the rotary drum, and a movable seat is supported above a base through a linear sliding rail on the bottom of the movable seat. The rear end of the movable seat is connected with a hydraulic oil cylinder through a force cell, wherein the hydraulic oil cylinder is used for providing push force, so that the tested tire can be pressed on the surface of the rotary drum. A swing bracket is arranged at the front of the movable seat, a rim fixing shaft used for mounting the tested tire is arranged at the front end of the swing bracket; one end of a swing shaft is fixedly sleeved on the swing bracket, and the other end of the swing shaft is rotationally sleeved on the movable seat in the axial direction; and a sliding angle driving hydraulic cylinder is arranged at one side of the swing bracket and is used for driving the tested tire to rotate with a certain angle along a radial tangent through the swing bracket.

Description

technical field

[0001] The invention relates to a device and method for high-speed / durability experiments of rubber tires, in particular to provide a detection device and a process method for simulating the slip angle friction between the tire and the road surface when the vehicle turns, and belongs to rubber machinery and automation field of production control. Background technique

[0002] With the increase of domestic automobile penetration rate and the increasing urban traffic congestion, the stability and safety of high-speed driving have become the core reference data for measuring the quality of tire design and production. In order to accurately detect the safety of tires under high-speed or long-term use, it is usually necessary to carry out high-speed / durability performance testing in the production process.

[0003] Based on the continuous innovation of current manufacturing technology, the tire high-speed / durability testing machine used by domestic and foreign ti...
