  • Patent number: 11002328
    Abstract: A shield assembly is employed for a friction brake used to decelerate a road wheel of a vehicle. The vehicle has a body with a first body end configured to face an incident ambient airflow, a second body end opposite of the first body end, and an underbody section spanning a distance between the first and second ends. The shield assembly includes a first shield component arranged proximate the brake and rotationally fixed relative to the vehicle body. The shield assembly also includes a second shield component operatively connected to the first shield component for shifting relative thereto. The shield assembly additionally includes an actuator employing a shape memory alloy element to shift the second shield component relative to the first shield component in response to a temperature of the brake to thereby direct at least a portion of the airflow to the brake and control temperature thereof.

  • Patent number: 10286973
    Abstract: A product may include a pair of handles that may be foldable. A wedge may be engaged between the pair of handles and may lock the pair of handles in a first position. A release mechanism may be connected to the wedge. Operation of the release mechanism may move the wedge to disengage from and to unlock the handles and may enable moving the pair of handles to a folded position.

  • Patent number: 10155568
    Abstract: A number of variations may include a product that may comprise a gear set, and first, second and third mechanical mechanisms. Each mechanical mechanism may alternatively be open or closed and each may be connected to the gear set. The mechanical mechanisms may be variously open or closed providing a number of gear ratios through the gear set. A fourth mechanical mechanism or a fixed connection may be included. A mode of operation may be provided where the first, second and third mechanical mechanisms are open, and the fourth mechanical mechanism may be closed or the fixed connection may be provided.

  • Publication number: 20180031065
    Abstract: An electromechanical brake system capable of conducting a brake pad wear check includes a structure defining a chamber, a member that rotates with a wheel, a motor mounted to the structure, a reciprocating piston, a brake pad, and a controller. The piston is driven by the motor between a variable actuated position and a retracted position. The brake pad is movably supported by the structure, operatively coupled to the piston, and adapted for braking contact with the member when the piston is in the actuated position, and spaced from the member when the piston is in the retracted position. The controller controls reciprocation of the piston between the actuated and retracted positions via energization of the motor, performs a brake pad wear check by calculating a change in a parameter associated with a change in distance between positions, and compares the change in parameter to a threshold value.

  • Patent number: 9475477
    Abstract: Systems and methods for reducing transient brake caliper drag in a motor vehicle are provided. The motor vehicle, for example, may include, but is not limited to, an axle, a rotor coupled to the axle, a brake caliper comprising a brake pad configured to engage the rotor, a brake pedal assembly communicatively coupled to the brake caliper, the brake pedal assembly configured to receive user input directing the brake pad to apply a force to the rotor and user input directing the brake pad to disengage the rotor, and a processor coupled to the brake caliper, wherein the processor is configured to determine, after the brake pedal assembly receives user input directing the brake pad to disengage the rotor, the force applied to the rotor, and command the brake caliper to retract the brake pad away from the rotor when the determined force exceeds a predetermined threshold.

  • Publication number: 20160123418
    Abstract: A wheel braking system includes a fluid source connected to an actuator that applies a force to a friction element for retarding rotation of the wheel. The braking system also includes a hydraulic circuit that has a first fluid passage providing direct communication between the fluid source and the actuator and a second fluid passage in communication with the first passage. The second fluid passage has a first portion and a second portion and includes a reciprocating piston assembly with a first piston fixed to a second piston for selectively amplifying a volume of the pressurized fluid received by the actuator. The first portion of the second passage is in fluid communication with the first piston and the second portion is in fluid communication with the second piston. The first piston has a first diameter and the second piston has a second diameter that is greater than the first diameter.

  • Patent number: 8631889
    Abstract: A vehicle includes a body that defines an opening in a forward end thereof. A heat exchanger and an inlet of a brake duct are each positioned rearward of the opening to receive a flow of air through the opening. A shutter system is movable between an open position to allow airflow through the opening and a closed position to block airflow through the opening. The shutter system controls the airflow to both the heat exchanger and to the inlet of the brake duct.

  • Publication number: 20130323525
    Abstract: An automotive product having a plurality of components coated with a refractory interface coating and method for making the same are provided. The automotive product may include at least a first component and a second component configured to interconnect and engage one another. The first component may be composed of a first high-density material. The second component may be formed of a second lower-density material. A refractory interface coating may be applied at the interconnection between the first and second components to provide an enhanced surface finish to limit friction, prevent metallurgical bonding between the first material and second material, provide a barrier against galvanic corrosion, and provide a thermal barrier between the first component and second component to guard against thermal deformation or change in dimension of the second component.
