Description

Technical Field

[0001] This utility model relates to the field of automotive parts, specifically to a lightweight sliding universal joint with a sliding rod section. Background Technology

[0002] Faced with an increasingly competitive market, there is a need for many high-performance, unconventional products to meet the complex demands. Currently, it is popular in domestic modified cars to pursue higher sway angles, lighter weight, greater slip travel, and longer service life; traditional slip-type universal joints can often only meet one or two of these requirements, and there are various limitations and complex issues to address. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, this utility model provides a lightweight sliding universal joint with a sliding rod, which mainly solves the problem that the sliding universal joint of the current drive shaft assembly is not comprehensive enough.

[0004] The technical solution of this utility model is as follows:

[0005] A lightweight sliding universal joint with a sliding member includes a housing and a connecting rod. The housing has a connecting tube, and a retainer is located inside the housing. The retainer has rolling elements that mate with the inner wall of the housing.

[0006] A groove is provided along the axial direction of the connecting pipe;

[0007] A cover, detachably connected to the inner wall of the housing, is used to separate the inner cavity of the housing from the sliding groove;

[0008] The second retainer is disposed in the slide groove and on the outside of the connecting rod extending into the slide groove. The second retainer is provided with a second rolling element.

[0009] A snap ring, connected to the inner wall of the connecting tube, is used to prevent the connecting rod from coming out.

[0010] The housing has a protruding ring inside, and the outer circumferential wall of the cover is engaged with the inner circumferential wall of the housing. The bottom outer wall of the cover is in contact with one end face of the protruding ring.

[0011] The rolling element is a steel ball.

[0012] The second rolling element is a steel ball.

[0013] The retaining ring includes a ring body with a protrusion on one side. The protrusion faces the direction of the groove opening. There is a gap between the ring body and the inner wall of the connecting pipe, and the ring body contacts the inner wall of the connecting pipe when it is deformed by force.

[0014] The bumps are provided in multiple ways.

[0015] It also includes a dust cover, one end of which is connected to the outer wall of the connecting pipe and the other end of which is connected to the outer wall of the connecting rod.

[0016] The beneficial effects of this utility model are as follows: This utility model provides a lightweight sliding universal joint with a sliding rod section. This product separates the sliding and swing functions of a traditional sliding universal joint. The connecting tube focuses on sliding, while the housing section focuses on swing, ensuring that they do not interfere with each other and fit tightly. In operation, it can transmit power well without the risk of losing power due to excessive angle. If one part has a problem, it will not affect the other, thus improving the safety performance of the product. Moreover, the hollow structure reduces the weight. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings: As shown in the figures, the lightweight sliding universal joint includes a housing 1 and a connecting rod 2. A connecting tube 20 is provided on the housing, and a retainer 3 is provided inside the housing. The retainer has rolling elements 31 that mate with the inner wall of the housing. It also includes a sliding groove 21 located axially along the connecting tube; a cover 11, detachably connected to the inner wall of the housing, used to separate the inner cavity of the housing from the sliding groove; a second retainer 4, located within the sliding groove and on the outside of the connecting rod extending into the sliding groove, with a second rolling element 41 on the second retainer; and a retaining spring 5, connected to the inner wall of the connecting tube, used to prevent the connecting rod from dislodging. The outer end of the connecting rod is used to connect to the differential. The grease in the housing and the grease in the connecting tube are different and cannot be mixed. This application reduces weight while preventing the two types of grease from mixing by separating the two cavities with a cover, thus improving service life.

[0022] In this embodiment, as shown in the figure, a protruding ring 111 is provided inside the housing. The circumferential outer wall of the cover is engaged with the circumferential inner wall of the housing, and the bottom outer wall of the cover contacts one end face of the protruding ring. The circumferential outer wall of the cover is engaged with the inner wall of the housing, and the rear end face rests on the protruding ring, making the overall installation stable.

[0023] In this embodiment, as shown in the figure, the rolling element is a steel ball.

[0024] In this embodiment, as shown in the figure, the second rolling element is a steel ball.

[0025] In this embodiment, as shown in the figure, the retaining ring includes a ring body 51, with a protrusion 52 on one side of the ring body. The protrusion faces the direction of the groove opening. There is a gap between the ring body and the inner wall of the connecting tube, and the ring body contacts the inner wall of the connecting tube when it is deformed by force. When the left side of the retaining ring is subjected to force (i.e., the impact force when the connecting rod moves outward), it will deform, and its protrusion will contact the inner wall of the connecting tube to prevent it from coming off. Under normal circumstances, the protrusion does not contact the inner wall of the housing. In addition, when removing it, applying force from the right side will not affect the normal removal.

[0026] In this embodiment, as shown in the figure, multiple bumps are provided, resulting in greater overall stability.

[0027] In this embodiment, as shown in the figure, a dust cover 6 is also included. One end of the dust cover is connected to the outer wall of the connecting pipe, and the other end is connected to the outer wall of the connecting rod. This prevents foreign objects from entering and increases service life.
