FR2715979A1 - Device for switching a gearbox by means of a synchronization device. - Google Patents

Abstract

The switching device comprises a switching sleeve (1) held in a neutral and switching position by pressure elements comprising balls (7) loaded by springs (9). The balls enter first recesses (2) of the inner peripheral surface of the sleeve where they are held and when a displacement force is applied to the switching sleeve, an axial pressure force is applied to a stop block (8 ) guiding a ball and a synchronization ring. In the inner peripheral surface of the sleeve is provided a second recess (3) connecting directly to the first recess (2), intended to cause increasing force peaks for the displacement force of the sleeve, with intermediate release of the synchronization. Between the two recesses as well as on the inner peripheral surface of the switching sleeve are provided transition edges (4, 5).

In this case, a com- plementary sentence is exer- cised on the block of arrt that guides the ball and a nnc ,, - u.,. of / nc: rnic ation by a force produced by the die. n of the switching unit.

  The positive say d. synchronization of the antennas of the Covenant is exemplified by an orem. a second, vitsse, include in a way that a synchronization function which is in turn activated. With a switching sleeve and which can be brought into contact with a coupling body of a flywheel by axial displacement A displacement force is created by the switching sleeve via a chilled ball. by spring and cooperating with the nmanchon, which causes the application of an axial compression force on a stop block and the synchronizing ring. This axial compression force acts on the sync ring and moves it smoothly. The synchronization ring and the friction ring then come out associated with the rotation torque of the input shaft on the one hand, while on the other hand the conical ring is associated with the speed of rotation of the drive shaft. output of 3utr_ z. rt.

The unit must be switched on to the switching point.

  The switching wire 1 comprises on its 220 internal peripheral su-face 6 two recesses 2 and 3 arranged one after the other and separated from each other by a transition edge 4. Another edge of transition 5 is provided between the second recess 3 and the inner peripheral surface 6. A ball 7 disposed in a stop block 3 is located opposite these recesses 2 and 3, which ball is applied under prestress against the switching sleeve i by a spring 9.

  In the direction of movement of the switching sleeve, for example from a first speed to a second speed of a gearbox, the recesses 2 and 3 are arranged directly one behind the other. The transition edge 4 between the two recesses 2 and 3 has an internal diameter "D" greater than that "d" of the other edge of -ransition 5.

  In the next position II, the control sleeve 1 has been moved in the direction of the arrow to establish synchronization and the ball 7 is pressed into the spring 9, so that the stop block is released. moved in the direction 13 towards the synchronization ring (not shown). The ball 7 determines when e ale passes on the transition edge i4 provided between the two recesses 2 and 3 a first re point 14 for the displacement force U of the switching sleeve 1.

  When the switching sleeve 1 continues to move, the ball 7 is disposed in the recess 3, for example in the hollow groove 11 or in the planar emptying 12. In this position III takes place a unlocking of the synchronization and U tonmbe displacement force up to a point 15 (FIG. 5).
