Definitions
- the invention relates to a switching device according to the preamble of claim 1.
- various components in the transmission are used to generate selector and switching forces.
- the components are used in particular to support the driver in guiding the shift lever in the shift lanes in accordance with the circuit diagram and at the same time to prevent damage to components in the transmission by the support.
- the driver of the vehicle should get a feel for the shift gate in which he is currently with his shift lever.
- Particular attention should be paid to the transition to those shift gates in which particularly small gear ratios are engaged or in which the gear ratio is shifted for reverse gear. If the gear ratio was too low or the reverse gear was switched without the vehicle conditions permitting it, in particular due to the speed being too high when the direction of travel was initiated without the vehicle coming to a standstill, the shifting device and in particular the synchronizers would be damaged.
- a selector arm designed as a lever, in the hub of which the selector or selector shaft is designed to be non-rotatable and axially displaceable via rolling elements engaging in axially extending guide grooves of the hub, is neutral against the force of at least one spring element fixed to the housing - in a dial position pivotable.
- the mounting of the selector rocker designed as a lever on the selector or selector shaft is very complex. Diameter reductions must be carried out in the selector or selector shaft to accommodate the rolling elements, which can impair stability.
- the invention has for its object to show a switching device that eliminates the disadvantages of the prior art.
- a sliding sleeve to be actuated in a selector gate is selected and rotated by the rotation of the selector or selector shaft switched by the subsequent axial shift the gear.
- a device that holds a rod is provided on the selector or selector shaft or on an auxiliary shaft that is actuated by the selector or selector shaft in order to form selection force profiles.
- the rod is operatively connected to a contour element, for example a lever, which is pivotally arranged in the gear housing.
- the contour element has a contour simulating the selection force curves, which acts on the rod in a spring-loaded manner.
- the selector shaft or selector shaft is rotated, which corresponds to a selection process, the rod slides along the contour of the contour element.
- a greater or smaller force must be applied when the selection or selector shaft is rotated by pressing the contour element against the spring element.
- the selection force on the contour can be taken off very directly.
- Any selection force curves can be represented by adapting the contour.
- the selection torque is transmitted to the contour element irrespective of the axial position of the selection or switching shaft or an auxiliary shaft controlled by the selection or switching shaft.
- a rotatable roller is provided on the rod, which is axially displaceable on the rod and interacts with the contour of the contour element and the device itself on the selector or selector shaft or an auxiliary shaft controlled by the selector or selector shaft is axially fixed. This ensures very little friction between the rod and the contour.
- a further advantageous embodiment shows the contour with its deepest bulge at a neutral position, which corresponds to an unactuated rest position of a shift lever in a selector gate.
- the shift lever in the shift diagram falls unactuated and without a gear stage being shifted to a position in the selector gate which usually corresponds to the position of the shift gate for the third / fourth gear.
- This aisle locking of the selector or selector shaft is brought about by the spring force of the spring element acting on the contour.
- Fig. 2 is an auxiliary shaft driven by a selector or switching shaft with a device arranged thereon.
- Fig. 1 shows a selector or switching shaft 2, on which two roller arms 4 are arranged at a distance from each other in a rotationally fixed and axially non-displaceable manner.
- the two roller arms 4 together hold a rod 6 which is firmly connected to the two roller arms 4.
- a roller 8 is provided on the rod 6 so as to be rotatable and axially displaceable.
- the roll 8 has a on its circumference Open 10.
- a lever 16, which can be pivoted about an axis 14, is arranged in a transmission housing 12.
- the lever 16 is supported on the gear housing 12 by a spring element 18.
- the lever In a central area, the lever has a contour 20 which is designed in accordance with the desired selection force curve.
- the deepest bulge 22 of the contour 20 corresponds to the neutral position of a shift lever, not shown here and connected to the selector or selector shaft 2.
- the contour 20 of the lever 16 engages in the groove 10 of the roller 8, whereby the roller 8 is fixed in its axial position on the rod 6.
- the roller 8 rolls on the contour 20 of the lever 16, while the roller 8 rotates around the rod 6.
- the spring element is subjected to a greater or lesser load during rotation, ie the driver feels a more or less large counterforce when the selector shaft 2 is rotated and can experience a feeling for the shift gate, into which he just put the gear lever when dialing. If the selector shaft 2 is shifted axially, the rod 6 is shifted within the roller 8 and the roller 8 is guided radially and axially on the contour 20 of the lever 16 without great friction.
- Fig. 2 shows a selector or shift shaft 2 on which a gear 24 is rotatably arranged.
- a gear 26 meshes with the gear 24 on an auxiliary shaft 28, so that when the selector shaft 2 is rotated, the auxiliary shaft 28 is also rotated.
- the gears on the Gears 24 and 26 overlap to such an extent that the toothing continues to mesh with one another even when axially displaced.
- the other arrangement of roller arms 4, rod 6 and lever 16 correspond to FIG. 1.
