Abstract
In a jaw-type gearshift for an at least two-stage gearbox, which is in particular electromotively driven, a ring-shaped shifting gate with a sliding block guide is provided, which has axially protruding shifting jaws and is in shifting contact by means of a shifting finger arranged on the sliding sleeve and engaging in the sliding block guide. In a method for shifting the jaw-type gearshift, the shifting jaws are coupled into corresponding receptacles of the gear wheels in that the shifting gate is moved axially relative to the sliding sleeve and the rise of the sliding block guide.
Claims15
A jaw-type gearshift for a gearbox comprising:
- a gear shaft;
- a first gear wheel arranged on the gear shaft;
- a second gear wheel arranged on the gear shaft;
- a sliding sleeve arranged axially displaceable relative to the gear shaft;
- and
- a ring-shaped shifting gate arranged between the gear shaft and the sliding sleeve, the ring-shaped shifting gate comprising axially protruding shifting jaws.
A method for shifting a jaw-type gearshift comprising:
- providing a sliding sleeve having a selection jaw, a shifting gate having a shifting jaw and a sliding block guide, and a gear wheel with a first receptacle for the selection jaw and a second receptacle for the shifting jaw;
- axially moving the sliding sleeve in a direction of the gear wheel until the selection jaw engages in the first receptacle;
- pivoting the shifting gate about an angle relative to the sliding sleeve;
- and
- axially moving the shifting gate by a slope of the sliding block guide in the direction of the gear wheel until the shifting jaw engages in the second receptacle.
A jaw-type gearshift for a gearbox comprising:
- a gear shaft;
- a sliding sleeve comprising:
- a radially inwardly pointing shifting finger;
- and
- a first selection jaw protruding from a first axial side of the sliding sleeve;
- and
- a ring-shaped shifting gate comprising:
- a sliding block guide in shifting contact with the radially inwardly pointing shifting finger;
- and
- a first shifting jaw protruding from a first axial side of the ring-shaped shifting gate;
- and
- a first gear wheel arranged on the gear shaft, comprising a first receptacle for receiving the first selection jaw and a second receptacle for receiving the first shifting jaw, wherein:
- the sliding sleeve is axially displaceable relative to the gear shaft;
- the ring-shaped shifting gate is arranged between the gear shaft and the sliding sleeve;
- the ring-shaped shifting gate is pivotable about a shifting angle relative to the sliding sleeve.
