Definitions

  • the present invention relates to a synchronous clutch for a spur gear, with a guide sleeve (synchronizer body) which is connectable to a shaft and having a guide sleeve toothing, with a sliding sleeve, which has a with the guide sleeve teeth engaging sliding sleeve teeth and with respect to the guide sleeve is axially displaceable, with a coupling body which is fixed to a gear and has a Kupplungsungs redesignveriereung into which the sliding sleeve teeth can be inserted to connect the guide sleeve and the coupling body rotatably with each other, and with a synchronizer ring of the type described above.
  • Locking synchronizer clutches for spur gear especially for motor vehicle transmission, are well known (see, for example, Looman, gear transmission, 3rd edition, 1996).
  • synchronizer clutches can be made without a separate spring / pressure piece system.
  • the spring element is formed in the manner of a leaf spring, which extends for example in the manner of a cantilever approximately along the axis of the synchronizer ring.
  • the spring element is designed to receive the presynchronizing force, but as a rule not to transmit the synchronizing force during the actual synchronization process, the spring element must deflect during the further synchronization process. Although this is generally possible in the circumferential direction. However, it is preferred if the spring element evades in the radial direction. In some applications (ASG), a transmission of the synchronous force is conceivable.
  • the synchronizer ring may be made of a forming steel, for example.
  • the sliding sleeve has a memorisnutabites which cooperates with the spring element and is arranged offset from an axial center of the sliding sleeve.
  • the spring element of the synchronizer ring can be assigned its own circumferential groove section on the sliding sleeve.
  • an outer circumferential radial recess of the guide sleeve for receiving the spring element wherein the bottom of the radial recess has a larger diameter than the inner diameter of the synchronizer ring.
  • the spring element of the synchronizer ring can be made very compact in the radial direction, for example according to the type of cantilever, it is also possible to increase the component strength of the guide sleeve. Because on the guide sleeve no far radially inwardly reaching recesses for receiving a spring / pressure piece system must be provided.
  • the examplesnutabitese are arranged so that a spring element of a switched synchronizer clutch engages in the other spring element associated ideasnutabites, so that when inserting the sliding sleeve teeth in the coupling body toothing a drag torque is reduced.
  • the spring element when the sliding sleeve toothing is inserted into the coupling body toothing, the spring element can deflect the spring element radially outward into the circumferential groove of the other synchronizer coupling, so that the contact pressure on the synchronizer ring is reduced. However, this also reduces the breakaway torque due to a frictional engagement between the friction lining of the synchronizer ring and the counter friction lining.
  • the means for limited circumferentially movable storage can be formed by the spring elements themselves, which then also absorb forces in the circumferential direction.
  • separate means for forming stop cams or the like may also be formed on the synchronizer ring and / or the associated components.
  • the clutch pack 10 includes a sliding sleeve 20 having an internal toothing (not shown in the figure), which is in engagement with the guide sleeve toothing. Accordingly, the sliding sleeve 20 in the axial direction parallel to the axis 15 back and forth. In Figure 1, the sliding sleeve is shown in a neutral position.
  • the guide sleeve 18 has a radially outwardly extending central web 32. In the region of its outer circumference, the guide sleeve 18 has a radial recess 34 for the two illustrated spring elements 26A, 26B. Its bottom has a larger diameter than the inner diameter of the synchronizer rings 24A, 24B.
  • a plurality of, for example, three spring elements 26 are distributed over the circumference of the synchronizer rings 24A, 24B.
  • radial recesses 34 are formed on the guide sleeve 18 in a corresponding number.
  • the circumferential groove portions 36A, 36B are offset from the axial center 28 and lie on opposite sides of the axial center 28.
  • the spring members 26A, 26B thus each have their "own" circumferential groove portion 36A, 36B.

Abstract

L'invention concerne une bague de synchronisation (24) pour un accouplement de synchronisation (12). La bague de synchronisation présente un corps de base (90) de forme annulaire à la périphérie extérieure duquel est formée une denture de blocage (25) et sur lequel est prévue une garniture de frottement (60), des moyens (94) qui permettent de monter la bague de synchronisation (24) à déplacement limité dans la direction périphérique par rapport à un manchon de guidage (18) associé étant en outre prévus sur le corps de base (90). Au moins un élément élastique (26) configuré pour transmettre une force axiale (54) de pré-synchronisation est fixé sur la bague de synchronisation (24).
