摘要： 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.

摘要： In an application, which refers to holding actuation of a parking brake mechanism (a rotation-linear motion conversion mechanism), a braking control apparatus (a parking brake control apparatus) determines an application stroke from a load detection point including as far as an overshoot amount. The load detection point is a generation point of a thrust force that is detected due to a current flowing in the electric motor. The overshoot amount is generated based on a rotation of an electric motor due to inertia after driving of the electric motor is stopped. The braking control apparatus determines a target release stroke in a release, which is release actuation of the parking brake mechanism, according to the application stroke. The braking control apparatus outputs a control instruction to conduct the release based on the target release stroke.

摘要： An electromechanical brake pressure generator for a hydraulic braking system of a vehicle. The brake pressure generator includes at least one threaded drive system including a spindle and a spindle nut, which cooperate via a thread, and an electromotive drive using which the spindle and the spindle nut are rotatable relative to one another. The brake pressure generator includes a hydraulic piston accommodated in a hydraulic cylinder of a piston/cylinder unit. An anti-twist protection is formed by a recess which extends in the axial direction and forms a sliding surface, and by a sliding element protruding into the recess, so that the hydraulic piston is secured against twisting and is axially displaceable by a rotation of the spindle. The sliding surface and/or a contact surface of the sliding element cooperating with the sliding surface includes a microprofiling, whose profiling direction is orthogonal to the movement of the hydraulic piston.

摘要： An apparatus for a drum brake assembly having a brake drum and an actuator includes a shoe spreader web with a first side for connecting to a first piston of the actuator and a second side for connecting to a second piston of the actuator. A first brake shoe is secured to the first side of the web. A second brake shoe is secured to the second side of the web. The brake shoes have a first condition in which the respective first and second sides of the web move the brake shoes to apply braking force to the brake drum in response to actuation of the actuator. The first brake shoe has a second condition moving relative to the web for absorbing brake drum contraction forces and prevent the full magnitude of these forces from reaching the actuator clevises.

摘要： Systems and methods for a power machine can provide greater functionality and operator comfort. A climate control system for a power machine can include a condenser, mounted on a front frame member of the power machine. Paths for air flow to cool an engine compartment can extend along airflow passages though a fuel tank. Secondary braking systems can allow a power machine to be stopped with modulated fashion when a primary power source is unavailable. Rear-view vision systems can include a camera mounted on a front pivoting frame (e.g., near the top of an operator station) to provide improved environmental information to an operator. A tilt actuator of the power machine can be configured to operate in a float mode.

摘要： A brake system for a motor vehicle has at least a first wheel brake and at least a second wheel brake. A first inlet valve is fluidically connected, on the one hand, to the first wheel brake, and, on the other hand, to a brake pressure source, and a second inlet valve is fluidically connected, on the one hand, to the second wheel brake, and, on the other hand, to the brake pressure source. In this case, a switching valve is provided, which fluidically connects the one fluid outlet of the second inlet valve in a first switching position to the second wheel brake and in a second switching position to the first wheel brake.
