Abstract

The invention discloses a stretchable spline shaft. The stretchable spline shaft comprises a first round shaft section, a first spline section, a shaft shaped like a Chinese character 'feng', a first connecting shaft, a hydraulic column, an oil adding nozzle, an external spline, a second round shaft section, a second spline section and a second connecting shaft. The two ends of the first round shaft section are connected with the first spline section and the shaft shaped like the Chinese character 'feng', the first spline section is connected with the hydraulic column through the first connecting shaft, and the hydraulic column is provided with the oil adding nozzle. Compared with the prior art, the stretchable spline shaft has the beneficial effects that the height of the spline shaft is changed, the spline shaft is suitable for different vehicles by changing the length, and the market practical degree of the spline shaft is higher.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to a retractable spline shaft. Background technique [0002] The spline shaft is a kind of mechanical transmission, and the flat key, half-round key, and oblique key have the same function, and they all transmit mechanical torque. There are longitudinal key grooves on the outer surface of the shaft, and the rotating parts on the shaft also have corresponding key grooves. Rotate synchronously with the axis. While rotating, some can also slide longitudinally on the shaft, such as gearbox shift gears, etc. [0003] Most of the spline shafts of today's vehicles are one-piece and cannot be stretched. Such a design is not conducive to the promotion of a type of spline shaft. The spline shaft that cannot change the length can only be applied to one type of vehicle. Contents of the invention [0004] The purpose of the present invention is to provide a retractable spline shaft, which can speed...
