  • Patent number: 11624413
    Abstract: Aspects of the technology relate to a braking assembly for a lateral propulsion system of a high altitude platform (HAP) configured to operate in the stratosphere. Power is supplied to a propeller assembly as needed during lateral propulsion so that the HAP can move to a desired location or remain on station. When lateral propulsion is not needed, power is no longer supplied to the propeller assembly and it may slowly cease rotating. However, in certain situations, it may be necessary to cause the propeller assembly to stop rotating as soon as possible. This can include an unplanned descent. Rapid braking can avoid the propeller blades from entangling in the envelope, parachute or other parts of the HAP. A reusable brake is employed to prevent uncontrolled rotation of the propeller on descent, or otherwise to prevent the propeller from spinning freely when not being used to propel the HAP laterally.

  • Patent number: 11365773
    Abstract: A multi-disc brake includes an annular brake coil holder with a wound brake coil, an armature plate with a disc support to which a multiplicity of armature plate discs is fastened. A compression spring brings about a linear spacing of the brake coil holder from the armature plate made of a ferromagnetic material in a braking position of the multi-disc brake and, when current is applied to the brake coil, a released position of the multi-disc brake can be created by attracting the armature plate in the direction of the brake coil holder. The braking effect results from the interaction of the armature plate discs with drive shaft discs on a drive shaft. The brake coil holder area of the brake coil holder and the cross-sectional area of the brake coil are substantially of rectangular single-legged design, and when installing the multi-disc brake, part of the wall of the drive support surrounds the brake coil on two sides and the brake coil holder on one side.

    Abstract: An electromechanical actuator (EMA) is disclosed. The EMA may comprise an EMA housing, a ball nut extending axially within the EMA housing, a ball screw extending axially within the ball nut, and/or an actuator drive unit (ADU) housing extending axially within the ball screw, the ADU housing having a proximal stop that extends radially outward of the ADU housing. The ball nut may be configured to translate axially in a proximal direction in response to a rotation by the ball screw, and the ball nut may be configured to be halted in the axially proximal translation in response to contact with the proximal stop. The proximal stop may be coupled to the ADU housing. The proximal stop may comprise a continuous annular structure.

  • Patent number: 9630601
    Abstract: A method that compensates for fluid pressure variations in a vehicle brake system so that the fluid pressure, brake torque and/or brake force at the wheel more accurately reflects that requested by the driver. In an exemplary embodiment, the method determines the braking intent of the driver, determines a current stage of the braking event (e.g., an apply stage, release stage, etc.), uses the braking event stage and the driver braking intent to select a pressure compensation, and uses the pressure compensation to generate compensated brake command signals for operating the vehicle brake system. This method is well suited for use with brake-by-wire systems, such as an electrohydraulic braking (EHB) system.

  • Patent number: 9593726
    Abstract: The invention relates to a disc brake for an aircraft wheel, comprising friction discs (20,30), including rotor discs and stator discs, a structure comprising a torsion tube (11) on which the discs are fitted, a rear plate (12) which is located at one end of the tube, and a support (13) for braking actuators (14,15) at another end of the tube, the actuators being able to be selectively activated in order to apply a pressing force to the discs. According to the invention, the discs are separated into two groups, including a first group (20) which can be used alone for taxiing braking operations, and a second group (30) which can be used alone or in conjunction with the first group for take-off/landing braking operations.

  • Patent number: 9475471
    Abstract: Based on a difference between target and actual values of a friction member force pressing a brake disc, feedback control over the pressing force is executed. As the actual value, a “limit pressing force (Fbs) obtained by placing a limitation on a temporal change amount of the Fba based on a limit value (Lmt)” is used. The limit value (Lmt) is set based on an electric motor speed (dMkt, dMka), a wheel speed (Vwa), and a temporal change amount (?Tmp) of the friction member temperature. The Lmt is set to increase as the dMkt (dMka) increases and the temporal change amount (?Tmp) of the temperature increases, and to also increase as the wheel speed (Vwa) decreases. Thus, even when a rotating member (brake disc) is deformed, braking torque control can be appropriately executed without accelerating a fluctuation of a braking torque on the wheel.

  • Patent number: 9297433
    Abstract: A parking brake actuator generates and applies a braking force to a vehicle wheel by converting a rotation movement of a screw member which is rotated by an electric parking brake driving device into a translatory movement and transmitting the converted translatory movement to a piston to push a brake pad to a disc by the piston. The electric parking brake driving device includes an electric motor and a reduction gear mechanism which transmits the driving force of the electric motor to the electric parking brake driving device. The reduction gear mechanism includes a pinion gear fixed to an output shaft of the electric motor, a first gear shaft rotatably supported on a first bearing member provided on a gear body and a first wheel gear formed on the first gear shaft and engaging the first wheel gear to thereby reduce the speed of driving force of the electric motor.

  • Patent number: 9187068
    Abstract: A method applying an electric park brake system of a vehicle includes detecting a park request with a first vehicle control module, and sending a park command, from the first vehicle control module, to both an electric brake control module and a second vehicle control module. Upon the electric brake control module receiving the park command, an actuation signal is sent from the electric brake control module to a motor winding of the electric park brake system. A status actuated signal is sent from the electric brake control module to the second vehicle control module. The status actuated signal indicates that the actuation signal has been sent from the electric brake control module. A position of the motor winding is sensed to determine if the motor winding is actuated. When the motor winding is actuated, a message is displayed to indicate that the electric park brake system is applied.

  • Patent number: 9145940
    Abstract: An electric brake system is proposed which includes an electric linear motion actuator and can generate the required braking force with high accuracy. A load sensor (30) is provided in a motion converting mechanism of the actuator which converts the rotary motion of a rotary shaft (4) to which the rotation of an electric motor (2) is transmitted to linear motion of an outer ring member (5) as an output member. The load sensor (30) detects the pushing force with which the outer ring member (5) linearly drives a driven member. With this arrangement, if the driven member is a braking member of an electric brake system, it is possible to directly detect the braking force applied by the driven member and thus to accurately generate the required braking force.
