Embodiment
Fig. 1 illustrates according to the present invention and the overall shaft assembly represented by figure notation 2.
Shaft assembly 2 comprises an axle 4, first constant velocity joint 6 and second constant velocity joint 8.First joint 6 is external joints, such as, be fixed on wheel, and the second joint 8 is such as the built-in joint of the vehicle be connected with power train.
Wheel W schematically illustrates, and represents first Parts for Power Train.Wheel W forms the cavity C with an abutment surface AS.At opposite side, power train comprises the Parts for Power Train DTE be such as connected with motor.Parts for Power Train also forms cavity C and an abutment surface.
Axle 4 limits central axis X-X, and comprises a core 10 and two end sections 12.
First constant velocity joint 6 is identical with the second constant velocity joint 8 structure, therefore only describes the first joint below.Second joint 8 and the first joint 6 specular.
First joint 6 comprises a positive component 14 and a female member 16.
Positive component 14 is three heel pieces with an axle sleeve 18 and three arms 20.Each arm 20 extends along a longitudinal axis Y-Y, and axis Y-Y opposing axial X-X radial direction extends.Each arm 20 comprises and is preferably cylindricality and is holistic outer working surface (running surface) 22 with axle sleeve 18.Each arm of positive component 14 has a roller 24, roller 24 have to contact with outer working surface 22 in working surface 26.
Therefore, joint 6 did not both have needle roller, was not carried by arm 20 yet and was arranged on the additional turns between roller and arm, this simplify its structure.Roller 24 is directly installed on arm 20.
Roller 24 has and is preferably spherical outer working surface 28.
Positive component 14 and roller 24 are without any the holding device remained on by roller 24 on arm 20, and when not having female member 16, roller 24 freely can be separated with arm 20 on the axial direction of its longitudinal axis Y-Y relative.
End sections 12 and axle sleeve 18 limit axial stop 30, and restriction axle sleeve 18 is relative to axle 4 moving axially towards core 10.Axial stop 30 comprises axle stop surface 32 and the axle sleeve stop surface 34 of cooperation.
End sections 12 and axle sleeve 18 also limit rotary fixing device, are fixed on axle by axle sleeve around central axis X-X at circumferencial direction.These rotary fixing devices comprise shaft spline 36 and the axle sleeve keyway 38 of cooperation.Rotary fixing device has gap, and when not having retainer 30 and spring 50, what allow positive component 14 opposite axial end 12 freely moves axially (see below).
Two joints 6 are identical with 8 structures, but the arm 20 of the first joint 6 staggers in a circumferential direction relative to the arm 20 of the second joint 8.
The layout of arm is shown schematically in Fig. 3.This illustrates the axial view along axle 4 central axis X-X.Be the axis of each arm 20 of the first joint 6 shown in figure, represent with Y1.Angle [alpha]=120 ° that three axis Y1 stagger around central axis X-X.
The axis of each arm 20 of the second joint 8 represents with Y2.Can see, the axis Y2 of each arm staggers with axis Y1 in a circumferential direction around central axis X-X.The angle staggered represents with β, and is 60 ° in the present case.
This axial cyclic vibration distribution that each joint 6,8 can be made to produce that staggers circumferentially is enclosed one, and the vibration force therefore produced is lower.This feature is conducive to the use that roller 24 directly runs on arm 20.
Female member 16 is tulip shape parts, has pair of tracks 40 to each roller 24.Female member 16 also limits groove 42, has the abutment surface 44 in the face of respective end part 12.Tulip shape part has power train axle head 43, complementary with the cavity C of corresponding Parts for Power Train W or DTE.
A helical spring 50 is inserted in groove 42, between tulip shape part and axle sleeve 18.Spring 50 reclines and props up the abutment surface 45 of abutment surface 44 and axle sleeve 18.Therefore spring 50 remains on positive component 14 on end sections 12, and pushes positive component 14 to core 10.
Therefore, the independent fixing device be fixed on by axle sleeve 18 on end sections 12 is not needed.
The helical spring 50 of joint 6 also has the function of axle spring assembly, at work axle 4 is pushed the precalculated position relative to relevant female member.Precalculated position is also limited by the helical spring 50 of the second joint 8, and this helical spring 50 forms auxiliary axle spring assembly.Axle 4 is pushed to the neutral position between female member 16.
Equally, the axle head 43 of female member 16 pushes in cavity C by spring 50, and leans an abutment surface AS.
First joint 6 also comprises radiation fins 60, closes the space that limited by female member 16 and is fixed on female member and axle 4.Radiation fins 60 is such as made up of rubber or TPE.
Fig. 4 illustrates the second embodiment according to shaft assembly of the present invention.Describe from the first embodiment at this different.Corresponding feature has identical figure notation.
Axle 4 is not pushed the spring 50 in its precalculated position by the second joint 8.
On the contrary, axle 4 has primary importance in its second end part 12 and determines surface 54, and this surface and the second place being arranged in tulip shape part 16 determine that surface 56 coordinates.
Primary importance determines that surface 54 and the second place determine that surface 56 is for partial spherical surface.
In general, one in the spring 50 of the first joint 6 or the second joint 8 is removed.Corresponding end sections 12 comprises spherical position and determines surface, and surface is determined in the spherical position that the groove 42 of corresponding female member 16 comprises complementation.Owing to only including a spring, the assembling of this modification is simpler.
Fig. 5 illustrates the front elevation of the details of joint 6, and radiation fins is omitted.
This joint has the holding device 70 being suitable for being remained on by positive component 14 in female member 16.These holding devices 70 comprise the plastic deformation part 72 of the tulip shape part in the axial profile extending to roller 24 or positive component 18.Holding device is axially disposed within the side of the opening of female member 16 corresponding positive component 14.Crushed element 72 is also shown in Fig. 6.
Or holding device 70 comprises the independent inserting member 74 be located in the opening of female member.This inserting member 74 is shown in Fig. 9.
Fig. 7,8 illustrates the details of positive component 18 further.
The shaft assembly 2 illustrated especially easily manufactures, and component part is little.Therefore it can be used for the automobile that manufacture cost is key factor.
As modification, helical spring 50 can be replaced with other spring assembly.
