In a shifting claw transmission for a motor vehicle including a main shaft and a countershaft and an electric motor for rotating the countershaft or being rotated thereby with freely rotatable gear wheels supported on the counter shaft and engageable with the countershaft by claw engagement structures, the speed of the countershaft is adjustable by the electric motor to be close to, but somewhat different from, the speed of the freely rotatable gear wheels to be engaged in order to facilitate shifting but avoid a tooth-on-tooth problem which would inhibit shifting.

Shifting claw transmission and shifting method therefor

In a motor vehicle, in particular a utility vehicle, having a shifting claw transmission and an electric motor connected to a countershaft of the transmission to facilitate central synchronization for gear speed changes, a transmission controller is connected to the electric motor for sensing the electric motor speed and, together therewith the rotational speed of the countershaft based on the induction values present in at the electric motor and sensed by the transmission controller for use in adjusting the energization of the electric motor.
