A brake chamber includes a chamber housing having an end, a push rod configured for reciprocal movement in the chamber housing in a first direction and a second direction over a stroke distance, a return spring disposed in the chamber housing configured to urge the push rod in the second direction and a sensor assembly having a sensor and a magnet movable relative to the sensor with movement of the push rod. The sensor is configured to detect a magnetic field strength of the magnet and output sensor data representative of the detected magnetic field strength. The sensor assembly is configured to determine a position of the push rod based on the sensor data over the entire stroke distance.

A combined cooling and water braking system for a vehicle comprises a first water recirculation loop having a first heat exchanger configured to cool water flowing in the first water recirculation loop, the first water recirculation loop comprising a water conduit for transporting heat away from a propulsion device configured to generate a propulsion power for the vehicle. A second water recirculation loop having a second heat exchanger is configured to cool water flowing in the second water recirculation loop. A retarder is configured to be coupled to a pair of wheels of the vehicle. The second water recirculation loop may be selectively used for cooling the propulsion device and for providing water to the retarder for water braking. There is also provided a method for cooling a propulsion device of a vehicle and water braking a pair of wheels of a vehicle.

A method for decelerating a vehicle includes actuating an electric brake motor of an electromechanical braking mechanism in an event of a failure of a hydraulic vehicle brake to produce a braking force in an event of a failure of the hydraulic vehicle brake. The method further includes producing a decelerating torque in the drive train of the vehicle in the event of the failure of the hydraulic vehicle brake. The vehicle includes a brake system. The brake system has the hydraulic vehicle brake and the electromechanical braking mechanism with the electric brake motor.
摘要:
A parking brake controller (19) activates an electric actuator (43) in response to operation of a parking switch (18) to hold a disc brake (31) to serve as a parking brake. If a failure (fault) is detected in the parking switch (18), the parking brake controller (19) activates the electric actuator (43) so as to hold the parking brake automatically upon detecting a condition that presumes the vehicle operator's intent not to drive any longer while the vehicle is at rest.

The present disclosure relates to shipping and storage containers. Specifically, the present disclosure relates to shipping and storage containers, which are traditionally stationary, converted to easily-portable containers. More specifically, the portable containers include a deployable/retractable landing/moving apparatus, a removable tow bar assembly, and leveling support systems. The portable containers can have many uses including as temporary to permanent housing, office space, and school rooms, or to house equipment for use in mobile telecommunication networks and systems, including cellular towers that can be set-up in both permanent and temporary locations.

A method for controlling a vehicle deceleration depending on a differential slip between two vehicle axles in a vehicle with an ABS brake system includes detecting at least one of a target vehicle deceleration specified by the driver and an actual vehicle deceleration; and controlling a braking pressure on wheel brakes of a vehicle axle to be controlled by actuation of ABS brake valves in such a way that the braking pressure on the wheel brakes of the vehicle axle to be controlled is controlled depending on a detected actual differential slip, so that the actual differential slip corresponds to a target differential slip. The actual differential slip indicates a difference in a rotational behavior of the vehicle axle to be controlled relative to a further vehicle axle. The target differential slip is dependent on at least one of the detected actual vehicle deceleration and the detected target vehicle deceleration.
摘要:
A hydraulic actuation device (1) for a brake device of a wind turbine including a hydraulic control line (10), which runs from a hydraulic system circuit (P) of a wind turbine to at least one brake cylinder (2) of a brake device. At least one restrictor (13) is arranged in the control line (10). At least one branch line (14) includes a pressure regulating member (15) that branches off from the control line (10) upstream of the restrictor (13) in the pressure build-up direction, bypassing the restrictor (13), and leads back into the control line (10) downstream of the restrictor (13). The pressure regulating member (15) open when the pressure present on the output side is low, but closes when the pressure at the pressure regulating member (15) on the output side of the pressure regulating member (15) exceeds a preset closing pressure (PS).

An electric vacuum pump includes a rotary member including an armature and a commutator; a brush arranged to slide in contact with the commutator; a motor part provided with a rotary shaft integral with the rotary member; a pump part connected to the rotary shaft and configured to operate in sync with the motor part; and a bearing supporting the rotary shaft between the motor part and the pump part, the commutator and the brush being placed on a non-pump side opposite to a pump side on which the pump part is placed in an axial direction of the rotary shaft with respect to the armature.
摘要:
To achieve a specifiable, and thus reproducible final pressure in at least one part of the brake circuit, the pump is first actuated for pressure buildup or pressure reduction when the valve is closed. When a first specified setpoint pressure is reached, or when a pressure threshold value is exceeded, the valve is put into an open position using a first actuation. After the pump is switched off, the actuation of the valve is modified in such a way that, during a specifiable time, a continuous change of the first actuation is undertaken all the way up to a second actuation, in which the valve assumes a holding position, particularly while taking into consideration the pressure difference which prevails at the valve.
