Abstract

A gear changing arrangement, which comprises an electric control system (Opticruise) is known to use in motor vehicles for changing gears in a gearbox having a plurality of gears. When a gear has been disengaged, a period without driving power is arisen before a synchronous motor speed is obtained where it is possible to engage a higher gear in the gearbox. The object of the invention is to reduce the duration of this period without driving power. According to the invention, the gear changing arrangement comprises a brake device, which is arranged to retard the motor speed to the synchronous speed where it is possible to engage a selected higher gear in the gearbox. Thereby, the motor speed will be reduced much quicker to the synchronous speed than with conventional technique. The brake device may be a friction brake, which is connected to a suitable rotary part of the motor.
