Drive shaft device 100 according to the ... of the embodiment of the present invention is described below with reference to Fig. 1.
Drive shaft device 100 according to the ... of the embodiment of the present invention may include：Differential mechanism 1, drive shaft 2 and clamp spring 3.
As shown in Figure 1, drive shaft 2 is inserted into and is coordinated with differential mechanism 1, engine or motor are transmitted into move
Power continues to pass to drive shaft 2 and wheel, and then drives vehicle traveling.Wherein, differential mechanism 1 has differential casing 11 and semiaxis
Gear 12, axle shaft gear 12 are located in differential casing 11, and drive shaft 2 and axle shaft gear 12 are in mating connection with by axle shaft gear
Torsion power on 12 passes to drive shaft 2, to ensure the connection of insertion depth and the two of the drive shaft 2 in axle shaft gear 12
Stability, the embodiment of the present invention is provided with the first jump-ring slot 121 on the inner peripheral surface of axle shaft gear 12, and makes the first jump-ring slot
121 open with two end surfaces of axle shaft gear 12.That is the first jump-ring slot 121 be arranged two end faces of axle shaft gear 12 it
Between, and be not connected with any one end face, the first jump-ring slot 121 coordinates the second jump-ring slot 21 and clamp spring 3 can guarantee and drives as a result,
The insertion depth and connective stability of moving axis 2.
Further, the second jump-ring slot 21 is provided on the peripheral surface of drive shaft 2, drive shaft 2 is mating in axle shaft gear
It in 12 and rotates synchronously to synchronize passing power, wherein the radial direction of the second jump-ring slot 21 and the first jump-ring slot 121 in drive shaft 2
Upper position corresponds to, and the cooperation of clamp spring 3 is in the first jump-ring slot 121 and the second jump-ring slot 21.Pass through clamp spring 3 and first as a result,
The limit of drive shaft 2 is connected in axle shaft gear 12, and can guarantee by the clamping engagement of jump-ring slot 121 and the second jump-ring slot 21
The connective stability of the two.
Further, the first jump-ring slot 121 carries out clamp spring 3 axial bidirectionally limited.I.e. in clamp spring 3 and the first jump-ring slot
121 and second jump-ring slot 21 be engaged by clamping after, drive shaft 2 has been limited at relatively fixed position and (has retained small play
Amount), insertion that can not be too deep, can not be from order to avoid the end face of drive shaft 2 and 13 phase of the planetary gear shaft shock in differential mechanism 1
Abjection in axle shaft gear 12, thereby it is ensured that the connective stability of drive shaft 2 and speed changer.
Drive shaft device 100 according to the ... of the embodiment of the present invention, the drive shaft device 100 use clamp spring 3 and the first jump-ring slot
121 and second mode that coordinates of jump-ring slot 21, and make the clamp spring after cooperation 3 in jump-ring slot by axial bidirectionally limited work
With, to ensure that drive shaft 2 and the connection depth of axle shaft gear 12 are fixed, and then the connective stability of both increases.
Embodiment as one preferred, the first jump-ring slot 121 are less than first at a distance from the inner face of axle shaft gear 12
Jump-ring slot 121 is at a distance from the outer end face of axle shaft gear 12.It is more convenient for as a result, machine-shaping, makes the manufacture of axle shaft gear 12 more
It is simple.
According to some embodiments of the present invention, the first jump-ring slot 121 has first axis limit anchor ring and the second axial limit
Position anchor ring, it is to be limited close to the face of differential casing end face 111, first axis in the first jump-ring slot 121 that first axis, which limits anchor ring,
Position anchor ring is for preventing drive shaft 2 from exiting axle shaft gear 12 along the axial direction of drive shaft 2, therefore, can effectively avoid drive shaft 2 from half
Abjection in shaft gear 12, ensures the connective stability of the two.
And the second axial limiting anchor ring is located at the inside of first axis limit anchor ring, it is close in as the first jump-ring slot 121
The face of planetary gear shaft 13, be used to prevent drive shaft 2 excessively stretch into an axial direction in axle shaft gear 12 and with planetary gear shaft 13
It is in contact and influences the normal transmission of power.
Embodiment as one preferred, the angle of the central axis of first axis limit anchor ring and drive shaft 2 is 45 °-
60°.It is obliquely installed for first axis limit anchor ring opposing axial.It as a result, can be in drive shaft 2 and axle shaft gear
Play the role of guiding when 12 assembly, drive shaft of being more convenient for 2 and the clamp spring 3 being arranged thereon are inserted into inside axle shaft gear 12.And
Also ensure that drive shaft 2 will not the abjection out of axle shaft gear 12.
According to some embodiments of the present invention, the central axis upright of the second axial limiting anchor ring and drive shaft 2.As a result,
It can enable the second axial limiting anchor ring that drive shaft 2 is effectively prevented to be inserted into the deeper inside of axle shaft gear 12, and then avoid driving
The end of axis 2 only abuts with 13 phase of planetary gear shaft and touches.
Referring to Fig.1, differential casing 11 has towards the differential casing end face 111 of wheel, and drive shaft 2 has and differential
The shaft shoulder face 22 of 111 face of device shell end face, shaft shoulder face 22 is spaced apart with differential casing end face 111.Wherein, differential casing
It is provided with oil sealing at end face 111, and is provided with dustproof cover at shaft shoulder face 22, oil sealing and dustproof cover fitted seal, to avoid the external world
Dust debris enter in differential mechanism 1.And shaft shoulder face 22 is spaced apart to setting with differential casing end face 111, along with the first card
The bidirectionally limited effect of spring slot 121, it is ensured that the relative friction between oil sealing and dustproof cover becomes smaller, and reduces to oil sealing and dustproof cover
Abrasion, thereby reduce the risk of oil sealing early stage oil leak, improve sealing and connection quality.
And it also can avoid since differential casing end face 111 caused by 2 axial float of drive shaft and shaft shoulder face 22 are mutual
The phenomenon that shock, can effectively promote the NVH performances of vehicle.
Embodiment as one preferred, the gap between shaft shoulder face 22 and differential casing end face 111 are not less than 1mm.
Due to consideration that clamp spring 3 and the first jump-ring slot 121 and the second jump-ring slot 21 are possible to not be complete clamping engagement, can exist certain
Axial movement surplus and there may be processing and manufacturing error situations such as, therefore, in shaft shoulder face 22 and differential casing end face 111
Between gap of the setting not less than 1mm can guarantee the matching degree of drive shaft 2 and differential mechanism 1 and avoid shaft shoulder face 22 and differential mechanism
Frictional impact occurs for shell end face 111.
As shown in Figure 1, axle shaft gear spline 122 is provided on the inner peripheral surface of axle shaft gear 12, on the peripheral surface of drive shaft 2
It is provided with drive shaft spline 23, drive shaft spline 23 coordinates with axle shaft gear spline 122, to ensure drive shaft 2 and differential mechanism 1
Connective stability, and realize the synchronous rotary of drive shaft 2 and axle shaft gear 12.
Further, the first jump-ring slot 121 be vertically opened on axle shaft gear spline 122 and with axle shaft gear spline 122
Both ends are spaced apart.Thus it can guarantee, clamp spring 3, will not be with semiaxis when snapping fit onto in the first jump-ring slot 121 and the second jump-ring slot 21
Gear spline 122 and drive shaft spline 23 are in contact influence, and then ensure the connective stability of drive shaft 2 and differential mechanism 1.
According to some embodiments of the present invention, the planetary gear shaft 13 of the inner face with differential mechanism 1 of drive shaft 2 is spaced apart.
It avoids drive shaft 2 to be in contact with planetary gear shaft 13 as a result, and influences normal power transmission between differential mechanism 1 and drive shaft 2.
