ABSTRACT:
Transmission method and arrangement for distributing tractive force in a vehicle between a first transmission branch (28a) and a second transmission branch (30). The transmission branches are connected to one another by way of a fork (28b) and one transmission branch (28a) is directly connectable to at least one wheel contact surface. The second transmission branch (30) is connected to the fork (28b) by way of a control unit (19), which is provided with control means (27) for varying the transmission ratio in this branch (30). The invention furthermore relates to a vehicle having at least two driving wheels (16, 16b, 17, 17b, 18, 18b) and the transmission arrangement specified above.
