Rubber wheel bogie train wheel positioning method

Abstract

The invention discloses a rubber wheel bogie train wheel positioning method which comprises the following steps: S1, before each rubber wheel bogie is subpackaged, adjusting wheel ends to enable leftand right toe-in values to be equal, adjusting a steering tie rod to enable a total toe-in value to be zero, and then locking to finish pre-positioning; S2, installing all the rubber wheel bogies withthe completion of pre-positioning on a whole vehicle, symmetrically installing multiple sets of detection targets on a left side and a right side of a vehicle body, and installing a camera sensor inthe center of each rubber wheel; S3, detecting the detection target by the camera sensor to obtain positioning parameters of each rubber wheel, wherein the toe-in value of the wheel is adjusted to a target value by adjusting a steering tie rod; if a propelling angle deviates leftwards, a cushion block is additionally arranged on a lower thrust rod on the left side; otherwise, a cushion block is added to a lower thrust rod on the right side, wherein the adding thickness is h, h = L*cos alpha, L is the distance between the lower thrust rod and the center of a frame, and alpha is the propelling angle. The method has the advantages of simple steps, no need of repeated detection, capability of quickly eliminating the thrust angle and the like.

Description

technical field [0001] The invention relates to a rubber-tyred bogie train, in particular to a wheel positioning method for a rubber-tyred bogie train. Background technique [0002] The wheel alignment angle is the relative angle between the suspension system and the moving parts, mainly including toe-in, camber, caster, kingpin inclination and propulsion angle, etc. Maintaining the correct wheel alignment angle can ensure that the vehicle Drive along a straight line, improve the steering performance of the vehicle, make the steering system automatically return to normal, avoid bearing damage and loss of precision due to improper force, and ensure that the rubber wheels are closely connected with the ground, reducing rubber wheel wear and suspension system wear, and Reduce fuel consumption, etc., and improve passenger comfort and safety. [0003] The four-wheel alignment detection technology is very mature in the automotive industry, and there are many positioning detection...

Problems solved by technology

However, the wheel alignment detection on rubber tires (that is, rubber wheels, which are different from traditional rail transit vehicles) on bogie trains mostly stays in the use of the above-mentioned locator to perform single-axis wheel alignment detection on each axle, which cannot be used for the entire vehicle bogie. The wheels are detected together, resulting in repeated detection process (for example, a 32-meter six-axle two-way driving rubber-tyred bogie train needs to be detected 6 times if it contains 6 axles), and the accuracy of the wheel positioning parameters of the whole vehicle is low. There are abnormal conditions such as poor steering performance and rubber wheel wear
