Problems solved by technology

[0003] The traditional cross shaft mounted on the split differential case is integral forging, and the cross shaft of this integral forging has the following deficiencies: (1) there is a forging defect in the integral forging, and when the vehicle is running in a harsh environment, due to the forging defect It is easy to cause the cross shaft to break: (2) the position accuracy of the four axes of the cross shaft is not easy to guarantee during processing, and the processing cost is high; (3) the position of the four axes of the cross shaft cannot meet the requirements, resulting in planetary gears and half Shaft gear meshing is not good, resulting in gear tooth failure when the vehicle is running

Embodiment Construction

[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0021] In the description of the present invention, it should be understood that the terms "first" and "second" are used for description purposes only, and cannot be interpreted as indicating or implying relative importance or implicitly indicating the quantity of indicated technical features. Thus, a feature defined as "first" and "second" may explicitly or implicitly include one or more of these features.

[0022] see figure 2 with image 3 , the long axis of the split type cross shaft, a pair of positioning grooves are provided in the middle of the long axis, and the pair of positioning grooves are symmetrically located on both sides of the axis of the long axis. Specifically, the axes of the pair of positioning grooves coincide and are perpendicular to the long axis The distance between the bottom of a pair of positioning grooves is 1 / 3 of the diameter...

Abstract

The invention relates to a long shaft of a split-type cross shaft. A pair of positioning grooves are formed in the middle of the long shaft and are symmetrically positioned in the two sides of the axis of the long shaft respectively; a pair of long shaft grooves are further formed in the positions, on the two sides of each positioning groove, on the long shaft respectively; two long shaft grooves in each pair of long shaft grooves are symmetrically positioned in the two sides of the axis of the long shaft respectively; a stop groove parallel to the long shaft along the axis is formed in each of the two ends of the long shaft. The long shaft of the split-type cross shaft is simple in structure and convenient to mount. Due to the formation of the pair of positioning grooves in the middle of the long shaft, the long shaft is more easily matched and fixed with a short shaft, and the position degrees of the long shaft and the short shaft are more easily determined.

Description

technical field [0001] The invention relates to the technical field of automobile control, in particular to a long shaft of a cross shaft of an automobile differential or a planetary reducer. Background technique [0002] The cross shaft of the automobile differential and planetary reducer is a very important part in the power transmission system of the automobile. It plays the role of power transmission, deceleration and speed regulation. The quality of its production is directly related to the safety and life of the automobile. [0003] The traditional cross shaft mounted on the split differential case is integral forging, and the cross shaft of this integral forging has the following deficiencies: (1) there is a forging defect in the integral forging, and when the vehicle is running in a harsh environment, due to the forging defect It is easy to cause the cross shaft to break: (2) the position accuracy of the four axes of the cross shaft is not easy to guarantee during pr...
