  • Patent number: 10184536
    Abstract: A brake piston assembly including a brake piston; a rotary to linear stage mechanism including a spindle and a nut; and a ball ramp assembly including a nut ramp plate and a piston ramp plate. The brake piston includes a piston pocket. The ball ramp assembly is located at a bottom wall of the piston pocket. The ball ramp assembly engages a side wall of the piston pocket so that the ball ramp assembly is maintained in the piston pocket after the ball ramp assembly is assembled in the piston pocket. Rotation of the spindle causes the nut to axially move until the nut directly contacts the nut ramp plate, and further axial movement of the nut causes the nut to move the ball ramp assembly and the brake piston against an inboard brake pad to create a clamp force.

  • Patent number: 10137870
    Abstract: Brake lock detection is described for a brake activation system. In one example, a main housing is configured to engage an interior surface of a towed vehicle near a brake pedal of the towed vehicle. An actuation arm extends away from the main housing configured to connect to the brake pedal to actuate a brake of the towed vehicle through the brake pedal. An arm drive system of the main housing applies a positive pressure to the actuation arm when activated to drive the brake pedal to actuate the brake. A negative pressure sensor generates a negative pressure signal when the brake pedal applies a negative pressure opposite the positive pressure to the actuation arm and the actuation arm is not activated.

  • Patent number: 10124783
    Abstract: A method for detecting the location of and isolating a leak in a braking system by simultaneously controlling a direct apply subsystem (DAS) and an isolated apply subsystem (IAS) to enable fluid communication between the IAS and the first circuit; to block fluid communication of the DAS with the first circuit; to enable fluid communication of the DAS with the second circuit; and to block fluid communication of the IAS with the second circuit. A sensed travel of an isolated apply component and a sensed fluid pressure developed by the IAS may be used to determine if the leak is present in the first circuit, while simultaneously using the sensed travel of a direct apply component of the DAS, and a sensed fluid pressure developed by the DAS, to determine if the leak is present in the second circuit.

  • Patent number: 10125839
    Abstract: The current invention discloses several methodologies that mitigate shock loading and propensity to resonance in agricultural spray boom structures. These include a near planar linkage for decoupling the boom assembly from the vehicle. This serves to permit further aspects of the invention to: Use the combined mass of the booms and center section as the tuned mass of a tuned mass damper: Act as an enabling part of a boom compliant suspension system to mitigate shock loadings otherwise imposed on the boom system, and: Act as an enabling part of an active boom height and roll control systems to permit the accurate navigation of the boom over undulating terrain. Further aspects include the incorporation of tuned mass dampers in the boom structure and components; and the use of the mass and operation of the boom outboard “breakaway” sections as tuned mass dampers.
