Abstract

The invention discloses an adjusting method and device for a transmission shaft intermediate support, and the method comprises the steps: obtaining the up-down displacement of a rear drive axle, and converting the up-down displacement into a point coordinate on an input axis, a point coordinate on an output axis, a central point coordinate of a cross shaft of each universal joint, and an included angle between a plane of a driving fork of each universal joint and a vertical plane of an axis of a driving shaft; calculating the equivalent included angle of the current transmission shaft by using a formula; according to the set variable, the z-direction coordinate value in the transmission shaft intermediate support center point coordinate is changed for multiple times, and the changed transmission shaft system equivalent included angle is determined one by one according to the set variable; comparing a plurality of transmission shaft system equivalent included angles, and determining an optimal z-direction coordinate value; and adjusting the current position of the intermediate support of the transmission shaft according to the optimal z-direction coordinate value. The adjusting device comprises a hydraulic lifting module, a displacement sensor and a control module. According to the invention, the accuracy and flexibility of transmission shaft equivalent included angle adjustment control can be improved.

Description

technical field [0001] The present application relates to the technical field of transmission shafts of commercial vehicle chassis, and in particular, to an adjustment method and an adjustment device for the intermediate support of the transmission shaft. Background technique [0002] In the field of commercial vehicle chassis drive shaft technology, the cross shaft universal joint is widely used because of its high reliability and low cost. In a drive shaft including a universal joint, the parameter for comprehensive evaluation of the drive shaft arrangement is the equivalent angle. When the equivalent angle of universal joint transmission is not zero, the rotational speed of the drive shaft will fluctuate, and at the same time, the bending moment of the fluctuating attachment will be generated on the drive shaft. The fluctuation of rotational speed will cause the gear tooth impact and noise of the transmission system, thus affecting the reliability of the transmission sha...
