Abstract

The invention provides a method for measuring the included angle of the semi-axis, which belongs to the technical field of automobile transmission system, including obtaining the coordinate data of the left semi-axis, fitting the first cylinder according to the coordinate data of the left semi-axis; obtaining the coordinate data of the right semi-axis, and Fit the second cylinder with the axis coordinate data; obtain the coordinate data of the installation surface, and fit the first plane according to the coordinate data of the installation surface, the installation surface is the installation surface of the motor and the reducer; measure the angle between the left half axis, and the angle between the left half axis is The angle between the axis of the first cylinder and the normal of the first plane; measure the angle of the right semi-axis, which is the angle between the axis of the second cylinder and the normal of the first plane . By transforming and fitting the vehicle measurement object into a virtual surface and line, the spatial relationship between the surface and the line is made clearer, and the angle between the line and the line can be directly measured to obtain the left semi-axis angle and the right semi-axis angle, Make the measured data more accurate.

Description

technical field [0001] The invention relates to the technical field of automobile transmission systems, in particular to a method for measuring the included angle of half shafts. Background technique [0002] Cars are the most commonly used means of transportation in daily life. With the improvement of people's quality of life, the requirements for the safety and comfort of cars are getting higher and higher. [0003] Such as Figure 5 As shown, in the vehicle transmission system, the half shaft 16 plays the role of transmitting the power output by the power assembly 18 to the wheels 15, so as to realize the driving of the vehicle. Since the powertrain 18 needs to consider many factors when it is arranged, the output axis of the differential (arranged at the end of the powertrain 18) cannot be coaxial with the axis of the wheel 15, which will make the axle shaft 16 and the differential There is a space angle between the output axes, which is referred to as the semi-axis ang...
