Embodiment Construction

[0051]In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0052] The embodiment of the present invention aims at the problems in the prior art that the ride comfort and straight-line driving performance of the car are reduced due to improper assembly of the tire assembly, and the fatigue coefficient of the driver is increased, and a method for installing tires on the rim is provided. Devices, controllers and systems; thereby reducing the vibration of the ground to the vehicle during driving and improving NVH performance.

[0053] Such as figure 1 Shown is the flow chart of the method for installing tires on rims according to the embodiment of the present invention. It should be noted that in the process of installing tires on rims, the tires to be installed first need to be installed on testing equipment contain...

Abstract

The invention provides a method, device, controller and system for installing a tire on a rim and relates to the technical field of automobile component installation. The method includes the steps that a first angle corresponding to the maximum value of a first harmonic component of radial force fluctuation and a second angle and a third angle which correspond to the maximum value of a second harmonic component in the process when the tire to be installed turns a circle are acquired; a first high point is obtained according to the first angle, and a second high point is obtained according to the second angle and the third angle; a fourth angle corresponding to the minimum value of the first harmonic component of radial force fluctuation and a fifth angle and a sixth angle which correspondto the minimum value of the second harmonic component in the process when the rim to be installed turns a circle are acquired; a first low point is obtained according to the fourth angle, and a secondlow point is obtained according to the fifth angle and the sixth angle; and a matched point and the assembling direction of the tire to be installed and the rim to be installed are determined according to the first high point, the second high point, the first low point and the second low point. By the adoption of the scheme, the NVH performance of a whole automobile is improved.

Description

technical field [0001] The invention belongs to the technical field of auto parts installation, and in particular relates to a method, a device, a controller and a system for installing a tire on a wheel rim. Background technique [0002] The uniformity of the tire assembly directly affects the shaking degree of the steering wheel, the degree of deviation of the automobile and the noise, vibration and harshness (Noise, Vibration, Harshness, NVH) performance of the automobile during driving. Among them, the installation method of the tire assembly is: the light point of the tire is set corresponding to the rim valve, or the light point of the tire is set correspondingly to the 180° direction of the light point of the rim. However, this installation method cannot effectively reduce the tire and rim valve. After the rim is assembled, the radial force fluctuates, so that during the driving process of the car, it is more likely to cause steering wheel vibration, wheel deviation o...
