Wherein, drive joint 27 to comprise that these two by driving the opposed free end face region 25,26 of the tooth clutch hub 1,2 of joint 27 in connecting, wherein, there is the state of common interlocking or the state of no-load running disengagement, nothing interlocking for the end region 25,26 that drives joint 27
Wherein, free end face region 25,26 comprises opposed shaping structure 23,24, described shaping structure is outline ground and coordination mutually each other on pattern respectively, thereby after throwing off, these two opposed shaping structures 23,24 again gather and when therefore shaping structure 23,24 is gathered again at these two opposed tooth clutch halfbodies 21,22, two shaping structures 23,24 are aimed at and are pushed into the corresponding shaping structure free space 39,40 of corresponding opposed another shaping structure 23,24 to suffer from one's own actions positive mode from contact beginning itself, and
Wherein, the tensioning nut 38 that utilizes lock ring 10 to be locked in the first tooth clutch hub 1 can axially be adjusted and be arranged in axle 19 with respect to clutch axis 18.
The first tooth clutch halfbody 21 has crowned teeth portion 17, and the second tooth clutch halfbody 22 has crowned teeth portion 16, and wherein, crowned teeth portion 16,17 is from centrally forming.
The adjustment region 32 of axle end regions side have than the height of head of tensioning nut 38 longer, the distance that increased spacing A.
The second tooth clutch halfbody 22 shown in Figure 3 is together with the longitudinal section of the axle 19 of fixing access.Axle 19 not only can fix by the screw thread in the second tooth clutch halfbody 22, and axle 19 there can be by the connection of force closure and/or the sealed connection of shape and/or the sealed connection of material, preferably bonding and welding fixes.At this, the second lid 6 of the second sleeve 4 remains on the second sleeve 4 by the second guard ring 11.Between the second lid 6 and the second sleeve 4, there is an O shape circle.
Band shown in Figure 4 is useful on the longitudinal section of the first tooth clutch halfbody 21 of the through hole 31 of axle 19, and wherein, the first tooth clutch hub 1 has the free space for adjusting the first tooth clutch halfbody 21 in the adjustment region 32 of axle 19.The first lid 5 of the first sleeve 3 is clamped on the first sleeve 3 by the 3rd guard ring 36.
The 2nd O shape circle 35 is between the first lid 5 and the first sleeve 3.In order to support the sealing to crowned teeth portion 16 and 17, can introduce respectively an annular seal element 14.
An exploded view shown in Figure 5, this exploded view comprise in the adjustment region 32 that is applied to axle 19, adjustable tensioning nut 38 there, comprise for tensioning nut 38 being locked in to the lock ring 10 in the first tooth clutch hub 1 and comprising the thrust washer 8 in the region that is arranged on contraction flow region 34, comprise with the first guard ring 9 moving for limiting tensioning nut 38 arranging to thrust washer 8.Tensioning nut 38 has internal thread 41 as shown in FIG. 5, described tensioning nut utilizes this internal thread in the threaded adjustment region 32 of arranging of axle 19, to be adjusted, wherein, adjustment can correspondingly cause being coupled and the corresponding decoupling zero that causes each clutch disk hub of clutch disk hub 1,2, and therefore can correspondingly cause being coupled and the corresponding decoupling zero that causes each clutch halfbody of clutch halfbody 21 and 22.
Shown in Figure 6 consider Fig. 2 in the situation that in decoupling zero state according to the longitudinal section of tooth clutch 30 of the present utility model, this tooth clutch have by that connect tooth clutch halfbody 21,22, from the drive joint 27 of centering.
Tensioning nut 38 in the first tooth clutch hub 1 is applied in axle 19.Lock ring 10 is locked in tensioning nut 38 in the first tooth clutch hub 1.With the form convergent of contraction flow region 34, wherein, there is the groove/circular groove 37 for holding lock ring 9 in the free end stepped shaft ground of axle 19, this lock ring locking thrust washer 8 in the region of contraction flow region 34.Between the head end of tensioning nut 38 and thrust washer 8, there is spacing A in this two tooth clutch halfbodies, 21,22 interlocking in the situation that, wherein, this spacing A equals the distance for the end region 25,26 of drive joint 27 completely being thrown off/is separated in no-load running at emergency operating.
In order to set up emergency operating, for example, between connected motor and be connected wheel, by the rotation in adjustment region 32, tensioning nut 38 is adjusted to spacing A, and will drive the disconnected from each other and decoupling zero of the end region of joint with this, and needn't dismantle the assembly of drive unit.
Thrust washer 8 use in the first tooth clutch hub 21 act on the docking location (Ansto β ort) of the tensioning nut 38 decoupling zero state, that adjust along the direction of clutch axis 18 causing shown in Fig. 6.In decoupling zero state, spacing A equals zero, wherein A=0, and tensioning nut 38 abuts on thrust washer 8, and drive joint 27 to throw off and separately.
Tension element/tensioning nut 38 therefore with thrust washer 8 and the first guard ring 9 combined form emergency operating fixed element.
Shown in Figure 7 according to the drive joint 27 of Fig. 2 be coupled state in the region vertical profile enlarged view of the expansion of the emergency operating fixed element of the tensioning nut 38 of the first tooth clutch halfbody 21, and shown in Figure 8 for example, according to the vertical profile enlarged view of the peripheral region of the tensioning nut 38 of (in emergency operating situation) first tooth clutch halfbody 21 in the decoupling zero state of the drive joint 27 of Fig. 6, wherein, in the disengaged condition of decoupling zero, the first tooth clutch halfbody 21 pushes away from the second tooth clutch halfbody 22 along clutch axis 18, thereby tooth clutch 30 is in the no-load running without interlocking.
The cross section of the end region 25,26 of these two tooth clutchs 1,2 has the shaping structure 23,24 being configured in the end-tooth portion of center contraction (zulaufen), described shaping structure has leg-of-mutton sawtooth, and the saw tooth structure of these sawtooth is opposite for from centering in the time that formation has the drive joint 27 of tooth shaping structure 23,24 to rabbet.
The manual centering required, bothersome according to prior art that can save the drive joint 27 that comprises sawtooth 23,24 to tooth clutch hub 1 and 2 in the time that these two tooth clutch halfbodies 21,22 are connected, wherein in simple mode
-by slowly rotating and carefully press the first tooth clutch hub 1 and carry out towards wheel direction,
-by discovering the first tooth clutch hub 1 during the final stage in interlocking towards obviously axially the snapping in of wheel direction,
Can implement the gathering from centering of these two tooth clutch halfbodies 21,22.
In axle 19, at least exist at least one bearing 12, particularly will be from driving at least one sliding bearing of the clutch component 1 that throw off of joint 27.
