First claim
Opening claim text (preview).
The invention claimed is: 1 . A portal axle arrangement ( 1 ) for a motor vehicle, comprising: at least one portal housing ( 2 ), the at least one portal housing ( 2 ) includes a receiving section ( 7 ) for a portal gear and at least one connecting section ( 8 , 9 ) extending from the receiving section ( 7 ), the at least one connecting section ( 8 , 9 ) being configured as a support section; and at least one suspension arm ( 5 , 6 ), each of the at least one suspension arm ( 5 , 6 ) being connectable to a respective one of the at least one connecting section ( 8 , 9 ) wherein each of the at least one suspension arm ( 5 , 6 ) is connectable to the respective one of the at least one connecting section ( 8 , 9 ) by a bolted connection. 2 . The portal axle arrangement ( 1 ) of claim 1 , wherein the at least one connecting section ( 8 , 9 ) has a curvature ( 10 , 11 ). 3 . The portal axle arrangement ( 1 ) of claim 1 , wherein the at least one suspension arm ( 5 , 6 ) is configured for supporting a spring force, and the at least one connecting section ( 8 , 9 ) and the at least one suspension arm ( 5 , 6 ) are connected to each other in a plane that is at least approximately parallel to a spring force direction ( 14 ) of the spring force. 4 . The portal axle arrangement ( 1 ) of claim 1 , wherein each of the at least one portal housing ( 2 ) has a homogenized transition between the receiving section ( 7 ) and the at least one connecting section ( 8 , 9 ). 5 . The portal axle arrangement ( 1 ) of claim 1 , wherein the at least one connecting section ( 8 , 9 ) and the at least one suspension arm ( 5 , 6 ) are form-lockingly connected to each other in order to transmit transverse loads. 6 . The portal axle arrangement ( 1 ) of claim 1 , wherein each of the at least one portal housing ( 2 ) is a cast housing and includes a cavity ( 15 ) that extends, starting from the receiving section ( 7 ), into the at least one connecting section ( 8 , 9 ). 7 . The portal axle arrangement ( 1 ) of claim 1 , wherein the at least one suspension arm ( 5 , 6 ) has an I-shaped or rectangular cross-section. 8 . The portal axle arrangement ( 1 ) of claim 1 , wherein the at least one suspension arm ( 5 , 6 ) is made of metal or fiber-plastic composite. 9 . The portal axle arrangement ( 1 ) of claim 1 , wherein: the at least one portal housing ( 2 ) comprises two portal housings ( 2 ); the at least one suspension arm ( 5 , 6 ) comprises four suspension arms ( 5 , 6 ); and the four suspension arms ( 5 , 6 ) are identically shaped. 10 . A motor vehicle, comprising the portal axle arrangement ( 1 ) of claim 1 . 11 . The portal axle arrangement ( 1 ) of claim 1 , wherein each of the at least one suspension arm ( 5 , 6 ) extends from the receiving section ( 7 ) to a free end ( 12 , 13 ), each of the at least one suspension arm ( 5 , 6 ) being connectable to the free end ( 12 , 13 ) of the respective one of the at least one connecting section ( 8 , 9 ).
