A device for adjusting camber and/or toe of a vehicle wheel includes a multi-part wheel carrier having a wheel-side carrier part, an axle-side guide part, and an adjusting member, in particular two rotary parts, arranged there between, by which the carrier part is swingable about a wobble point for toe and/or camber adjustment of the vehicle wheel. A bearing point is formed radially outside of the adjusting member, on which the carrier part and the guide part are articulated to one another. The bearing point is designed in a firm manner in the wheel-axle circumferential direction for support of the carrier part which is subjected to a brake torque, and is designed in a soft manner to realize a trouble-free adjustment and, compared with the wheel-axle circumferential direction, a particularly smooth adjustment of the carrier part about the toe and/or camber angle in the vehicle transverse direction.

A brake system for a motor vehicle includes separate first and second brake circuits associated to first and second vehicle axles, respectively, and rigidly connected to each other. Hydraulic brake pressure is supplied by a first brake piston of a master cylinder to the first brake circuit and by a second brake piston to the second brake circuit. Operably connected to the first vehicle axle is an electric motor and operates as a recuperator, with a blending device withdrawing hydraulic fluid from the first brake circuit during a recuperation phase of the electric motor. A partition wall between the first and second brake pistons subdivides the master cylinder into a first pressure chamber associated to the first brake piston, and a separate second pressure associated to the second brake piston. A connectable and disconnectable floating piston enables a hydraulic communication between the first and second brake circuits with one another.

A hydraulic brake system includes two brake circuits, a tandem master brake cylinder which is connected to the two brake circuits and includes a float piston, and a means for adjusting a position of the float piston, wherein a defined distribution of brake power between the two brake circuits is commensurate with the position of the float piston.

A steering stop for a steer-by-wire steering system, includes a steering shaft for functionally connecting to a steering wheel, wherein a pressure chamber is provided for each direction of rotation of the steering shaft. A rotation of the steering shaft produces a reduction in the volume of a corresponding pressure chamber, and the steering stop also comprises a hydraulic valve such that resistance against a further rotation of the steering shaft is generated by the operation of said hydraulic valve when predetermined environmental conditions are met.
