Abstract
A motor vehicle with a chassis which has at least two axles. A subframe is associated with one of the axles and is connected to the chassis and on which the at least two wheels of the respective axle are each mounted and held by way of a single-wheel suspension, and with at least one bearing device for elastically connecting the subframe to the chassis, which permits relative movements between the subframe and the chassis. A balancing between comfort and performance can be improved with at least one connection device for rigidly connecting the subframe to the chassis, which is switchable between an open state in which the connection device permits relative movements between the subframe and the chassis, and a closed state in which the connection device prevents relative movements between the subframe and the chassis.
Claims10
A motor vehicle comprising:
- a chassis having at least two axles, each axle having at least two vehicle wheels forming a front axle with at least two front wheels and a rear axle with at least two rear wheels,
- at least one subframe, which is associated with one of the axles, and is connected to the chassis and on which the at least two wheels of the respective axle are each supported and held by way of a single-wheel suspension,
- at least one bearing device for elastically connecting the subframe to the chassis, which at least one bearing device permits relative movements between the subframe and the chassis, and
- at least one connection device for rigidly connecting the subframe to the chassis, which at least one connection device is switchable between an open state (OS) in which the connection device permits relative movements between the subframe and the chassis, and a closed state (CS) in which the connection device prevents relative movements between the subframe and the chassis.
