    Abstract: A vehicle axle may include hydraulically operating wheel brakes and/or additional hydraulic loads, such as clutch plate cylinders. The vehicle axle may include at least one pressure supply device, driven by an electric-motor drive, to control pressure in the wheel brakes; at least one control and regulating device; a valve assembly having values for setting wheel-specific brake pressures and/or for disconnecting/connecting the wheel brakes from/to the pressure supply device, and at least one electric drive motor for driving and braking a vehicle wheel or the axle. At least one pressure supply device is used to control the pressure of and/or provide pressure to at least one additional brake unit in the form of an electric parking brake, a hydraulically supported electromechanical brake, an electromechanical brake and/or a force-supporting steering device, a gear actuator and/or transmission actuator, and/or a torque vectoring module.

    Abstract: A brake apparatus, for electrically driven motor vehicles, includes a traction motor at an axle of a vehicle, which traction motor is used both as drive motor and as brake system with recuperation of brake energy, a first piston-cylinder unit, which is actuatable by means of an actuating device, in particular brake pedal, a second piston-cylinder unit, which is actuatable by means of an electromotive drive and a non-hydraulic gearing apparatus, in particular spindle drive. The piston-cylinder units are connected via hydraulic connecting lines to wheel brakes of the motor vehicle. A pressure chamber of the first piston-cylinder unit is connected to two wheel brakes of a vehicle axle, and a pressure chamber of the second piston-cylinder unit is connected to a vehicle axle for active brake force feedback control and recuperation control in interaction with the traction motor.

    Abstract: A brake device for a motor vehicle with two axles, including at least one axle with an electric traction motor for driving and braking at least one wheel arranged on the axle, where energy can be recovered by means of the traction motor during braking. Each wheel has a wheel brake. A pressure supply is provided in the form of a piston-cylinder unit, which can both build up pressure and reduce pressure. The pressure supply forms part of a pressure supply device, having at least two connections, switchably connected by respective valves, to the brake circuits, an ABS/ESP unit and/or an actuating unit. An open-loop and closed-loop control device controls the at least one electric traction motor and components of the pressure supply device such that a braking deceleration can be set by closed-loop control for each brake circuit and/or each axle, with different braking torques at the respective axles.

    Abstract: The invention relates to an apparatus having a plurality of hydraulic actuators (Si) and a piston-cylinder unit (K), one working chamber (AK1) of which is connected, via at least one hydraulic connection line (HL) and supply lines (ZLi), to working chambers (ASi) of the hydraulic actuators (Si), wherein each working chamber (ASi) of a hydraulic actuator (Si) is connected to a supply line (ZLi) and switch valves (EVi) for selective opening and closing of the hydraulic supply lines (ZLi) are provided such that, in the opened position of the associated switch valve (EVi), a pressure change in the working chamber (ASi) of the actuator (Si) or an adjustment of the actuator (Si) can occur, wherein at least one pressure sensor (DSi) for determining the pressure in a working chamber (ASi) of an actuator (Si) or a hydraulic line (HL, ZLi, ALi) and a control device (ECU) is provided, characterized in that, for simultaneous pressure change in at least two actuators, (Si, Sk), the (ECU) permanently opens the switch valve (EVi) associated with a first actuator (Si) during the pressure change phase and adjusts or regulates the pressure by adjusting the piston (KK) of the piston-cylinder unit (K), and in that the control device (ECU) adjusts or regulates the pressure in at least one additional actuator (Sk) by means of the switch valve (EVk), which is clocked during the pressure change phase, and in particular is controlled by pulse width modulation.
