Description
(1) technical field
The utility model relates to a kind of four-wheel motor cycle drive shaft device, particularly a kind of drive axle device that can transmit various direction torsion.
(2) background technology
At present, four-wheel motor cycle is commonly two wheel drive, and its type of drive is generally spline, semi-round key, flat key, sprocket wheel chain, belt-driving etc., and they are simple in structure, have and transmit performance preferably.But it all can only transmit the torsion of a direction, and when being subjected to the power of other directions, its sport is affected, and also can be damaged when excessive as external force.Especially the motion of all directions such as up, down, left, right, before and after can appear in the front-wheel of four-wheel motor cycle in traveling process, and above-mentioned type of drive can not satisfy its operating needs.
(3) summary of the invention
The purpose of this utility model provides a kind of multidirectional drive axle device.It is simple in structure, can transmit multiple direction torsion.
For reaching above-mentioned purpose, the utility model end separately is on the chamber inner peripheral wall of cylindrical cover, bell-jar of axle, is respectively equipped with at least 3 axial notches.End at axle puts the inner race that circumference is provided with at least 3 grooves, with back-up ring location, places steel ball with the groove equal number in groove, with the retainer location, forms as a wholely, places in the chamber of cylindrical cover, blocks cylindrical cover cover mouth with snap ring; The other end at axle puts the inner race that circumference is provided with at least 3 grooves, with back-up ring location, places steel ball with the groove equal number in groove, with the retainer location, forms as a wholely, places in the chamber of bell-jar.
Owing to adopted said structure, inner race of the present utility model contacts by the steel ball sphere with retainer, and axle can be done multi-aspect rotation with sphere centre, thereby realizes the torsion output of wheel under all directions stressing conditions.And the length of the groove on the cavity wall of cylindrical cover, bell-jar is greater than the diameter of steel ball, and steel ball can slide in groove, the fulcrum of axle when regulating different pivot angle.
The utility model is described in further detail below in conjunction with drawings and Examples.
(4) description of drawings
Fig. 1 is a structure diagram of the present utility model;
Fig. 2 is that the A-A of Fig. 1 is to cutaway view.
(5) specific embodiment
Referring to Fig. 1, Fig. 2, the axle of cylindrical cover 1 is connected with the gear spline in the front gear box 14.On the cavity wall circumference of cylindrical cover 1, equidistantly be provided with 6 axial notches, and mouthful vertical with cover.The axial length of each bar groove can slidably reciprocate steel ball 4 greater than the diameter of steel ball 4 therein.End at axle 7 puts the equidistant inner race 5 that is provided with 6 circular grooves of circumference, adopts spline to connect, and by behind back-up ring 3 location, the steel ball 4 of placement and groove equal number is in groove, with nonconcentric cage 2 location.Inner race 5 and nonconcentric cage 2 be for sphere contacts, the inner arc surface concentric of the exterior arc surface of inner race 5 and nonconcentric cage 2.6 steel balls 4 cooperate with 6 circular grooves on the inner race 5 by retainer 2 respectively, consist of the relatively turnable integral body in inside, place in the chamber of cylindrical cover 1, and make 6 steel balls 4 respectively with cylindrical cover 1 cavity wall on groove fit.Block cylindrical cover 1 cover mouthful with interior snap ring 6, prevent that retainer 2 from deviating from cylindrical cover 1.Axle 7 the other end puts the equidistant inner race 11 that is provided with 6 circular grooves of circumference, adopts spline to connect, and by behind back-up ring 12 location, places steel ball 10 with the groove equal number in groove, with retainer 9 location.Inner race 11 and retainer 9 be for sphere contacts, the inner arc surface concentric of the exterior arc surface of inner race 11 and retainer 9.6 steel balls 10 cooperate with 6 circular grooves on the inner race 11 by retainer 9 respectively, consist of the relatively turnable integral body in inside, place in the chamber of bell-jar 8, and make 6 steel balls 10 respectively with bell-jar 8 cavity walls on groove fit.On the chamber inner peripheral wall of bell-jar 8, equidistantly be provided with 6 axial notches, groove be arc axially, and vertical with the cover mouth.The axial length of each bar arc groove can slidably reciprocate steel ball 10 greater than the diameter of steel ball 10 therein, because of groove be arc axially, make the cover mouth less relatively, can prevent that retainer 9 from deviating from bell-jar 8.The bearing that the axle of bell-jar 8 passes front arm system 15 is connected with front-wheel mounting support 13 splines.
Because 6 grooves in the cylindrical cover 1 are equivalent to the female splines that spline transmits, and with the relatively turnable integral body in inside that inner race 5, retainer 2, steel ball 4 are formed, are equivalent to the male splines that spline transmits.When multidirectional stressed, the relatively turnable integral body in inside by inner race 5, retainer 2, steel ball 4 are formed rotates with respect to cylindrical cover 1.When it turned to certain angle, retainer 2 interfered with cylindrical cover 1, and retainer 2 stops operating, and formed the location.Because inner race 5 and retainer 2 be for sphere contacts, thus inner race 5 and retainer 2 can also to do with the sphere centre be that the multi-aspect of the center of circle relatively rotates.The function of bell cover 8, steel ball 10, retainer 9, inner race 11 and in like manner last.
During working gear in the current drive gear casing 14, gear driven cylindrical cover 1 is rotated.And by steel ball 4,7 rotations of inner race 5 drive axles; Axle 7 drives bell-jar 8 and rotates by inner race 11, steel ball 10 again; Bell cover 8 drives front-wheel by front-wheel mounting support 13 and rotates, thereby realizes the driving of front-wheel.
In the motor bike operational process, when wheel is subjected to ground shock, can beat up and down, front arm system 15 can be around the upper and lower swing of two attachment points, and bell-jar 8 is swing thereupon also.Because inner race 5,11 contacts for sphere with retainer 2,9, it is that the multi-aspect of the center of circle relatively rotates that inner race 5,11 and retainer 2,9 can be done with the sphere centre, under the relative angle unmodified state that guarantees cylindrical cover 1, bell-jar 8, realize the torsion output of wheel under various stressing conditions.Simultaneously, because of cylindrical cover 1 the axle be fixed on the front drive gear case 14, its swing fulcrum different with the swing fulcrum of front arm system 15, front arm system 15 is in the process that swings up and down around two attachment points, in the length difference of different angle axles, this just requires can regulate length in the axial direction.Because the length of cylindrical cover 1 further groove is greater than the diameter of steel ball 4, steel ball 4 can be in groove inwards, outwards slide, played the effect of adjusting shaft to length.When steel ball 4 cylindrical cover 1 in the time, axially the shortest; When steel ball 4 during, axially the longest at cylindrical cover 1 outermost.The groove of bell-jar 8 also has identical effect.
At least 3 of the quantity of cylindrical cover 1 groove, the quantity of inner race 5 upper grooves, steel ball 4 is identical with it.
At least 3 of the quantity of bell-jar 8 grooves, the quantity of inner race 11 upper grooves, steel ball 10 is identical with it.
