Transfer case for vehicles and method for distributing a driving force on two vehicle axles

摘要

Transfer case for distributing a driving force of a drive of a vehicle to a first axis (9) and a second axis (8) of the vehicle, wherein the transfer case is disposed between the first axis (9) and the second axis (8) and a planetary gear (3 ) with two central wheels (4, 5) and a circumferential web (6) with at least one gear (7) and an electric machine (2), wherein the electric machine (2) with an element (4, 5, 6) of Circuit gear (3) is connected and one of the other two elements of the epicyclic gear (3) with the first axis (9) and the other of the other two elements of the epicyclic gear with the second axis (8) is connected, wherein the distribution of the driving force the first and the second axis (9, 8) take place by driving the electric machine (2), wherein the planetary gear (3) is a planetary gear with two central wheels (4, 5) and a planet carrier (6) with at least one planetary gear (7), characterized in that between the planet carrier (6) and the first axis (9) an additional switching element (21) is arranged to connect the planet carrier (6) with a sun gear (4) and to interrupt a connection to the first axis (9).
