Description

Technical Field

[0001] This utility model relates to the field of automotive parts, specifically to a high-performance assembly with large slippage. Background Technology

[0002] With the continuous development of the automotive industry, people have increasingly higher requirements for the overall performance of automobiles. In automotive transmission systems, to ensure that the output shaft and input shaft, which are in the same plane, rotate at the same speed, a constant velocity joint drive shaft assembly with double universal joints is often used. The constant velocity joint drive shaft assembly is the power transmission device between the automotive engine and the drive wheels. It provides the traction and speed required by the vehicle under various operating conditions, while allowing for coordinated changes and a sufficient range of variation to ensure that the left and right drive wheels can adapt to differential requirements.

[0003] The sliding of commonly used drive shaft assemblies is usually achieved through the sliding of intermediate shafts, but the conventional structure has insufficient sliding range to meet the requirements. Utility Model Content

[0019] The present invention will be further described below with reference to the accompanying drawings: A high-performance assembly with large sliding range includes an intermediate shaft 1, one end of which is provided with a first universal joint 2, and the other end with a second universal joint 3. The intermediate shaft includes a first shaft 11 connected to the first universal joint, and having an axially provided first sliding groove 111; a connecting pipe 12, a portion of which is axially movable within the first sliding groove, and having an axially provided second sliding groove 121; and a second shaft 13 connected to the second universal joint, a portion of which is axially movable within the second sliding groove. The intermediate shaft achieves a single-stage sliding range, and the second shaft achieves a second-stage sliding range, resulting in a large overall sliding range that meets usage requirements.

[0020] In this embodiment, as shown in the figure, a first retainer 112 is also included, disposed within the first groove and on the outside of the connecting pipe. A first rolling element 113 is provided on the first retainer, and the first rolling element slides in cooperation with the inner wall of the first groove and the outer wall of the connecting pipe. Grooves can be formed on the inner wall of the first groove and the outer wall of the connecting pipe, and then the first rolling element slides within the grooves.

[0021] In this embodiment, as shown in the figure, a second retainer 122 is also included, which is disposed in the second groove and on the outside of the second shaft. A second rolling element 123 is provided on the second retainer, and the second rolling element slides in cooperation with the inner wall of the second groove and the outer wall of the second shaft.

[0022] In this embodiment, as shown in the figure, the inner wall of the second slide groove is provided with retaining rings 124, which are located on both sides of the second retainer. This prevents the retainer from coming off and makes it more stable to use.

[0023] In this embodiment, as shown in the figure, the circumferential outer wall of the connecting pipe is provided with a retaining ring 125, and also includes a compression spring 126. One end of the compression spring contacts the retaining ring, and the other end contacts the first retainer. This serves as a buffer.
