Device with track for simulation test on characteristics of double automobile tires running on pavement

Abstract

The invention discloses a device with a track for the simulation test on characteristics of double automobile tires running on the pavement. A computer and an air conditioner outdoor unit are arranged outside a soundproof room, the base in the soundproof room is provided with a drum, the bottom in the drum is provided with an alternating current (AC) variable frequency motor, a speed reducer and a main shaft, the AC variable frequency motor is connected with the speed reducer by a belt transmission mechanism, the speed reducer is connected with the main shaft by the belt transmission mechanism, the upper end of the main shaft is provided with a track, a rotary arm is arranged in the track, the left end of the rotary arm is provided with a left axle, the lower end of the left axle is provided with a left automobile test wheel, the right end of the rotary arm is provided with a right axle, the lower end of the right axle is provided with a right automobile test wheel, the inner sidewall of the drum is provided with an air conditioner indoor unit, the air conditioner indoor unit is communicated with the air conditioner outdoor unit by pipelines, a drum upper cover is arranged on the top of the drum and is provided with a rotation speed senor which is connected with the computer by leads, the left axle is provided with an audio sensor connected with the computer by the leads, and the right axle is provided with a camera connected with the computer by the leads.

Description

technical field [0001] The invention belongs to the technical field of vehicle inspection, and in particular relates to the characteristic inspection of the interaction between tires and road surfaces. Background technique [0002] With the increasing attention to the environment, noise detection has become an important technical means for testing the environmental performance of road surfaces and tires at home and abroad. In road surface design and tire design, it is necessary to use test equipment to test the driving performance of the road surface and the dynamic performance of the tire to provide a basis for product development. [0003] At present, most of the test devices developed at home and abroad to simulate the driving of automobile tires on the road are horizontal shaft type, and there are roughly two types. One is the tire external drum type automobile tire dynamic characteristic test bench, which fixes the test tire Outside the wall of the drum, the tire is dr...
