Abstract
A locking arrangement on a selector lever for a motor vehicle transmission has an electromagnetic clutch which receives current from a circuit. This clutch consists of a magnetic clamp and of a check plate which can be moved about a pivot axis. When supplied with current, the check plate, when the clutch is closed, adheres to the magnetic clamp and blocks a locking pin. The locking pin is arranged transversely with respect to the selector lever and engages in an indentation of a connecting link, whereby a swivelling of the selector lever is prevented. This arrangement is small, light weight, can be integrated completely into the selector lever and can be released when a preload is exercised on the locking arrangement.
Claims19
A locking arrangement for a selector lever of a motor vehicle transmission, the selector lever being swivellable about a first axis, comprising:
- a locking pin which is manually shifted, said locking pin extending transverse to the selector lever;
- an electromagnetic clutch which includes a solenoid constructed as a magnetic clamp and which includes a check plate constructed as a locking mechanism;
- an electronic circuit connected to said solenoid, said solenoid moving said locking mechanism such that the locking mechanism blocks the locking pin from shifting and locks the selector lever;
- and
- wherein said clutch holds the check plate on the magnetic clamp via an electromagnetic holding force generated via an electric current supplied to said clutch in order to block the locking pin from shifting.

- wherein said clutch holds the check plate on the magnetic clamp via an electromagnetic holding force generated via an electric current supplied to said clutch in order to block the locking pin from shifting;
- and
- wherein the locking pin, via a clip displaceable together with the locking pin and provided with a first wedge surface, is brought to rest against a corresponding second wedge surface of the check plate, the first and second wedge surfaces being angularly arranged causing a release force directed against the holding force.
