Gear shifting unit

A gear shifting system (1), for use with a transmission shaft (8) having shaft driving toothing (5) the gear shifting system comprising:

• a gear shift sleeve (2) configured to be guided with a sleeve driving toothing (4) in an axially displaceable manner on the shaft driving toothing (5) of the transmission shaft (8) and can thereby be positioned on the transmission shaft (8) in at least three shift positions in which the gear shift sleeve (2) produces a respective rotationally fixed connection of the transmission shaft (8) to a respective transmission component (16;
• 17;
• 18);
• wherein at least one tooth (19) of the shaft driving toothing (5) is respectively equipped on at least one respective tooth flank (31, 32) and has projections (27 to 30) which each project in a peripheral direction relative to the at least one respective tooth flank (31, 32) and which are configured axially along the respective tooth (19) between respectively adjacent regions (20, 21, 22) in which teeth (23, 24) of the sleeve driving toothing (4) are moved axially in the shift positions of the gear shift sleeve (2);
• and
• wherein a gap width (34) of a respective gap (33) between the teeth (23, 24) of the sleeve driving toothing (4) is greater than or equal to a sum formed by a tooth width (35) of the at least one tooth (19) of the shaft driving toothing (5) which engages in the respective gap (33) and an effective width of the projections (27 to 30) in a peripheral direction of the at least one tooth (19).
