Embodiment Construction

[0023] The present invention will be further explained below in conjunction with the drawings:

[0024] Vehicle tire vibration device in parking state with adjustable amplitude. The device includes box 3, upper push rod 4, crankshaft 5, lower push rod 7, tire parking platform 8 and driving machine; upper push rod 4, push down The rod 7 and the crankshaft 5 are arranged in the box 3, the crankshaft 5 is a rotatable structure, the crankshaft 5 is connected with the driving machine, and the crankshaft 5 is divided into a small amplitude section 13 with a small eccentricity and a large amplitude section 14 with a large eccentricity. Both the amplitude section 13 and the large amplitude section 14 are provided with a lower push rod 7, and the lower push rod 7 is arranged on the crankshaft 5 through a bearing. Each lower push rod 7 corresponds to an upper push rod 4. The rod 4 is a structure that can be temporarily fixedly connected and then linked. When the lower push rod 7 and the up...

Abstract

A vibration amplitude-adjustable apparatus for exciting an automobile tyre in a parking state is disclosed. the device comprises a box body, upper push rods, a crankshaft, lower push rods, a tyre parking platform and a driver, wherein the upper push rods, the lower push rods and the crankshaft are arranged in the box body, the crankshaft is a rotatable structure, fixing screw bolts of two groups of outer side push rods are fixed when large vibration amplitude is required, fixing screw bolts of inner side push rods are dismounted, and the outer side push rods are in a working state while the inner side push rods reciprocate in a twitching manner accordingly; when small vibration amplitude is required, the fixing screw bolts of two groups of the inner side push rods are fixed, the fixing screw bolts of the outer side push rods are dismounted, the inner side push rods are in a working state, and the outer side push rods reciprocate in a twitching manner accordingly. Springs on guide rods and support springs below the automobile tyre parking platform can well exert damping effects, and impact exerted on the exciting apparatus by a vibrating automobile can be alleviated.

Description

Technical field [0001] The invention belongs to the technical field of vibration control, and in particular relates to an automobile tire vibration excitation device in a parked state with adjustable amplitude. Background technique [0002] Nowadays, the field of automobile industry is developing rapidly, and the types of automobiles are becoming more and more abundant. The static load experiment of traditional automobile parts can no longer meet the requirements of automobile experiment. Automobile fault diagnosis also increasingly relies on the use of excitation devices to stimulate vibration to simulate the vibration of the vehicle when it is parked. The parts of the car are loaded differently under various working conditions. When working for a long time, the car is prone to fatigue damage to the main parts of the car such as the suspension due to the vibration of the bad road conditions. The service life of the car is determined by the fatigue life of its parts. Decided. H...
