Abstract
The utility model relates to a kind of telescopic shaft of universal-joint, has a main shaft and a countershaft; One end of described main shaft is connected with universal joint, and the other end is provided with the sleeve pipe coordinated with countershaft; One end of described countershaft is connected with universal joint, and the other end is slidably arranged in the sleeve pipe of main shaft; The inwall of described sleeve pipe is provided with the main chute extended in the axial direction; The circumferential surface described countershaft being slidably arranged in inside pipe casing is provided with the secondary chute corresponding with main chute; Ball set is provided with between described main chute and secondary chute.The utility model telescopic effect is good, and during use, noise is little, and working life obviously increases.
Description
Technical field
The utility model relates to a kind of transmission shaft, particularly a kind of telescopic shaft of universal-joint.
Background technique
The telescopic shaft of universal-joint common is at present generally axostylus axostyle spline slide formula constant-velocity transmission shaft.Although the structure of this telescopic shaft can meet usage requirement, use after certain hour, the Strike note that due to spline tooth looseness, automobile can send when starting to walk " lattice, lattice ".Vehicle body can be shaken.When automobile changes the speed of a motor vehicle under steam, especially when slowing down, sound is more obvious.Also there is following problem in existing shrinking structure: be sliding friction between splined shaft and spline housing, easily wear and tear, the problem that working life is not high simultaneously.Generally can be arranged with a dirt-proof boot in the outside of universal joint, this dirt-proof boot can effectively prevent dust from entering the working life that universal joint affects universal joint.Transmission shaft is got into dirt-proof boot due to air and is caused irregular bulging when flexible, thus dirt-proof boot fold part contact closely produces static friction extremely, greatly reduces the working life of dirt-proof boot.
Model utility content
The purpose of this utility model is to provide a kind of long service life, uses noise little, the telescopic shaft of the steady universal-joint efficiently of telescopic effect.
The technological scheme realizing the utility model object is: the utility model has a main shaft and a countershaft; One end of described main shaft is connected with universal joint, and the other end is provided with the sleeve pipe coordinated with countershaft; One end of described countershaft is connected with universal joint, and the other end is slidably arranged in the sleeve pipe of main shaft; The inwall of described sleeve pipe is provided with the main chute extended in the axial direction; The circumferential surface described countershaft being slidably arranged in inside pipe casing is provided with the secondary chute corresponding with main chute; Ball set is provided with between described main chute and secondary chute.
The inwall of above-mentioned sleeve pipe is provided with the many circumferentially equally distributed main chutes in face; The circumferential surface described countershaft being slidably arranged in inside pipe casing is provided with the many secondary chutes corresponding with main chute; Ball set is equipped with between the secondary chute that described each main chute is corresponding with it.
The inwall of above-mentioned sleeve pipe is provided with six circumferentially equally distributed main chutes in face; The circumferential surface described countershaft being slidably arranged in inside pipe casing is provided with six secondary chutes corresponding with main chute; Ball set is equipped with between the secondary chute that described each main chute is corresponding with it.
The bottom of above-mentioned sleeve pipe is provided with the spring extended along its axial direction.
The utility model has positive effect: (1) the utility model is different from traditional flat key or spline shrinking structure, traditional flat key or spline shrinking structure are easy to wearing and tearing, thus occur coordinating tension, excessivelys loose, shake and the problem such as abnormal sound, and the utility model adopts ball set, rub less, during use, noise is little; (2) the utility model adopts six groups of ball set coordinated with main chute and secondary chute, better can realize location, and ensure torsion; (3) the utility model is provided with spring in the bottom of sleeve pipe, can effectively prevent because countershaft and main shaft clash into the noise sent, and effectively improves the working life of main shaft and countershaft; (4) spring in the utility model effectively can alleviate the use pressure of the dirt-proof boot being used in universal joint joint, improves the working life of dirt-proof boot.
