Abstract
The invention provides a front transmission shaft of a mine truck. The front transmission shaft comprises a transmission shaft pipe, wherein spherical cage type universal joint assemblies are arranged on shaft necks at the two ends of the transmission shaft pipe respectively to commonly form a constant-speed transmission system; each spherical cage type universal joint assembly comprises a bell housing shell, and each bell housing shell is internally provided with a plurality of balls through a retainer; star-shaped sleeves are arranged on the shaft necks of the transmission shaft pipe; the plurality of balls roll on the outer surfaces of the star-shaped sleeves to commonly form the spherical cage type universal joint assemblies; and a dustproof cover is further arranged between each bell housing shell and the transmission shaft pipe and is fixed through a hoop. By utilizing the constant-speed transmission system composed of the transmission shaft pipe and the spherical cage type universal joint assemblies, engine torque is stably transmitted to a speed changing box, and thus noises of the transmission system are reduced; the front transmission shaft has a light structure and is convenient to mount; the transmission efficiency is greatly improved, and the weight is light; and the vibration of the whole transmission system is reduced, and the whole transmission system is protected.
Description
Technical field
The present invention relates to the drive system of mine car, specifically mine car front propeller shaft.
Background technology
The power transmission shaft that mine car uses at present is all non-constant-velocity transmission shaft, non-constant-velocity transmission shaft rotating speed is higher, run at a low speed the unconspicuous automobile chassis vibration problem of performance more and more prominent, and traditional non-constant-velocity transmission shaft to there is cardan-shaft tube heavier, there is the waste of self；Travel simultaneously because mine car is always low-speed motion, the transmission accuracy of non-constant-velocity transmission shaft is just had no idea, and (installation requirement is required high than constant-velocity transmission shaft by main variable speed power transmission shaft in realization, big to the vibration effect of drive system), cause the waste of whole drive system and the power of electromotor output to can not get implementing (non-constant-velocity transmission shaft transmission efficiency is low compared with constant-velocity transmission shaft) to greatest extent.
Summary of the invention
The present invention is in order to alleviate the power transmission shaft weight of mine car and change transmission accuracy, and spy proposes mine car front propeller shaft.
The technical scheme is that for this, mine car front propeller shaft, including transmission shaft tube, it is characterised in that: it is respectively equipped with rzeppa joint assembly on the axle journal at transmission shaft tube two ends, collectively constitutes constant speed drive's system.
Further it is improved by: described rzeppa joint assembly also includes Bell jar shell, in Bell jar shell, is provided with multiple ball by retainer；The axle journal of transmission shaft tube is provided with inner race, and multiple balls roll at the outer surface of inner race, are collectively forming rzeppa joint assembly.
Further it is improved by: between Bell jar shell and transmission shaft tube, be additionally provided with dust cover, and fixed by clip.
Beneficial effect:
The present invention uses transmission shaft tube and constant speed drive's system of rzeppa joint assembly composition; smooth transfer engine torque is to change speed gear box; reduce drive system noise; light structure is easy for installation, transmission efficiency is greatly improved; lightweight; reduce whole driveline vibrations, whole drive system is protected.
The moment of torsion that the setting smooth transfer electromotor of rzeppa joint assembly transmits so that this Product processing becomes simple possible, uses reliable.
The setting of dust cover protects transmission shaft tube and the junction point of rzeppa joint assembly, prevents dust and muddy water in the presence of a harsh environment to the erosion of assembly and injury.
Accompanying drawing explanation
Fig. 1 is the agent structure schematic diagram of the present invention.
In figure, 1 is transmission shaft tube, and 2 is rzeppa joint assembly, and 3 is Bell jar shell, and 4 is ball, and 5 are to maintain frame, and 6 is inner race, and 7 is dust cover, and 8 is clip.
Detailed description of the invention
The present invention is as shown in Figure 1.
Mine car front propeller shaft, including transmission shaft tube 1, the axle journal at transmission shaft tube 1 two ends is respectively equipped with rzeppa joint assembly 2, collectively constitutes constant speed drive's system.
Rzeppa joint assembly 2 also includes Bell jar shell 3, is provided with multiple ball 4 by retainer 5 in Bell jar shell 3；The axle journal of transmission shaft tube 1 is provided with inner race 6, and multiple balls 4 roll at the outer surface of inner race 6, are collectively forming rzeppa joint assembly 2.
Between Bell jar shell 3 and transmission shaft tube 1, it is additionally provided with dust cover 7, and is fixed by clip 8.
The present invention changes the traditional idea of mine car; structure in conjunction with passenger car; the transmission accuracy making mine car is greatly improved; constant speed drive's system, smooth transfer engine torque to change speed gear box, reduces drive system noise; light structure is easy for installation, transmission efficiency is greatly improved; lightweight, reduce whole driveline vibrations, whole drive system is protected.
