Abstract

The utility model belongs to the technical field of the car transmission shaft, a transmission shaft sliding shaft is disclosed. The main technical characteristics are as follows: the lubricating oil guide device comprises a sliding shaft and a sliding fork, wherein the sliding fork is provided with an oil passage hole, a lubricating oil cup is arranged at the oil passage hole, and at least one annular oil guide groove is formed in the position, corresponding to the lubricating oil cup, of the sliding shaft. The utility model provides a transmission shaft sliding shaft is provided with one at least annular oil guide groove with the corresponding department in lubricating cup position on the sliding shaft. The annular groove is arranged on the outer circle of the spline on the outer wall of the sliding shaft. At the transmission shaft later maintenance in-process, when filling grease through the lubricating cup, the grease is full of the annular and leads oily recess, and the slip pair that sliding shaft and slip fork constitute is at the slip in-process, and grease can flow to each spline keyway in the oily recess is led to the annular, fully guarantees the vice effective lubrication of slip, effectively guarantees the vice lubricated effect of slip, promotes transmission shaft life.

Description

Transmission shaft sliding shaft

Technical Field

The utility model belongs to the technical field of the car transmission shaft, especially, relate to a lubricated effectual transmission shaft sliding shaft of spline.

Background

The rear axle transmission shaft used on the automobile comprises a sliding shaft and a sliding fork, and lubricating grease needs to be filled after the sliding shaft and the sliding fork are assembled so as to ensure that the sliding shaft and the sliding fork are sufficiently lubricated, avoid early abrasion of a spline and prolong the service life of the transmission shaft. Because the fit clearance between the sliding shaft and the tooth side of the sliding fork is small, the sliding shaft and the tooth side of the sliding fork cannot be fully filled on each spline in the later maintenance process and oil is filled, so that a sliding pair cannot be effectively lubricated, the early abrasion of the splines is caused, the abnormal sound of a transmission shaft is caused, and the service life of the transmission shaft is shortened.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to provide a lubricated effectual transmission shaft sliding shaft of spline.

In order to solve the technical problem, the utility model discloses a technical scheme does: the lubricating oil guide device comprises a sliding shaft and a sliding fork, wherein the sliding fork is provided with an oil passage hole, a lubricating oil cup is arranged at the oil passage hole, and at least one annular oil guide groove is formed in the position, corresponding to the lubricating oil cup, of the sliding shaft.

The utility model provides a transmission shaft sliding shaft is provided with one at least annular oil guide groove with the corresponding department in lubricating cup position on the sliding shaft. The annular groove is arranged on the outer circle of the spline on the outer wall of the sliding shaft. At the transmission shaft later maintenance in-process, when filling grease through the lubricating cup, the grease is full of the annular and leads oily recess, and the slip pair that sliding shaft and slip fork constitute is at the slip in-process, and grease can flow to each spline keyway in the oily recess is led to the annular, fully guarantees the vice effective lubrication of slip, effectively guarantees the vice lubricated effect of slip, promotes transmission shaft life.

Detailed Description

The following describes the structure of the sliding shaft of the transmission shaft according to the present invention in further detail with reference to the accompanying drawings.

As shown in fig. 1, the utility model provides a transmission shaft sliding shaft includes sliding shaft 1 and slip fork 2, and slip fork 2 is provided with oil duct hole 3, and oil duct hole 3 department is provided with lubricating cup 4, and sliding shaft 1 is last to be provided with one at least annular with the corresponding department in lubricating cup 4 position and leads oily recess 5.

As shown in fig. 2, the sliding shaft 1 is provided with an annular oil guide groove 5.

As shown in fig. 3 and 4, the slide fork 2 is provided with a mounting hole 3.

The utility model provides a transmission shaft sliding shaft is provided with one at least annular oil guide groove 5 with the corresponding department in 4 positions of lubricating cup on sliding shaft 1. An annular groove 5 is provided on the outer circumference of the spline of the outer wall of the slide shaft 1. At the transmission shaft later maintenance in-process, when filling the grease through lubricating cup 4, the grease is full of the annular and leads oily recess, and the slip pair that sliding shaft 1 and slip fork 2 constitute is at the slip in-process, and grease can flow to each spline keyway in the oil recess 5 is led to the annular, fully guarantees the vice effective lubrication of slip, effectively guarantees the vice lubricated effect of slip, promotes transmission shaft life.

The utility model provides a transmission shaft sliding shaft is not only limited to above-mentioned structure, and the all is in the utility model discloses any modification, equivalent replacement and improvement etc. of doing on the basis all should be contained within the protection scope.

Claims
