Abrégé

In a method for operating a motor vehicle with an electric drive, steering of the wheels (11) of the at least one axle assembly (2) having steerable wheels takes place only by means of drive and/or braking forces which act around the respective wheel axle (13). In the case of the presence of a corresponding driving situation, commands are output in a plurality of first time windows by an electronic control system, using which commands the wheels (11) of this axle assembly (2) are fixed in their angular positions and different drive and/or braking forces are exerted on the right-hand and the left-hand wheel (11), in order to transmit different longitudinal forces to the underlying surface. In a plurality of second time windows, commands are output by the control system, using which commands the swivelling of the wheels (11) is released by the holding device (31, 38) and the angular positions of the wheels (11) are modified about the respective swivelling axis (14) by means of drive and/or braking forces.

Abrégé

In a platform for at least four-wheeled motor vehicles with an electric drive, the right and the left wheel (11) of at least one axle assembly (2) can be steered and are driven individually by a respective electric motor (15). The hub carriers (12) of the right and left wheel (11) are coupled to one another via rod parts (28, 29) connected to the hub carriers (12) and via an adjustable connection unit (30) interconnecting the rod parts (28, 29). The wheels (11) are steered only by driving and/or braking forces. Using at least one actuator (31, 44, 47, 57) of the adjustable connection unit (30), the distance between the right and left connection point (30a, 30b), via which the connection unit (30) is connected to the respective rod part (28, 29), can be actively adjusted or a change in the distance between the right and left connection point (30a, 30b) can be enabled or blocked.

• B62D 9/00 - Direction pour roues orientables non prévue ailleurs

Abrégé

The invention relates to a platform for at least four-wheeled motor vehicles with electric drives, comprising at least one front and at least one rear axle assembly which are mutually spaced in the longitudinal direction of the platform and at least the front axle assembly of which has wheels (11) that can be steered about a respective pivot axis (14), are mounted on wheel supports (12) in a rotatable manner about wheel axes (13), and are individually driven by electric motors, wherein the wheel supports (12) which can be pivoted about the pivot axes (14) are connected together via a connection rod (31). The wheels (11) are steered solely by means of drive and/or brake forces. The platform has a modular design and has a chassis module (1) and a front axle module (2) which forms the front axle assembly and which can be connected to the chassis module (1) and can be removed from the chassis module (1) as a whole.

Abrégé

The invention relates to a platform for at least four-wheeled motor vehicles with electric drives, comprising at least one front axle assembly, which forms a front axle, and at least one rear axle assembly, which forms a rear axle, said assemblies being mutually spaced in the longitudinal direction of a supporting platform base (la) of the platform and at least the front axle assembly thereof having left and right wheels (11) that can be steered about a respective pivot axis (14), are mounted on wheel supports (12) in a rotatable manner about wheel axes (13), and are individually driven by electric motors. The left and right wheel supports (12) which can be pivoted about the pivot axes (14) are connected together via a connection rod (31). The wheels (11) are steered solely by means of drive and/or brake forces. The wheels (11) of the front axle assembly are suspended by means of a longitudinal control arm wheel suspension which has at least one right and at least one left longitudinal control arm (20, 21), each of which can be pivoted about a transverse axis (24, 22), said wheel supports (12) being pivotally connected to the longitudinal control arm (20, 21) about the respective pivot axis (14).
