| 20080296103 | Caliper brake - A hydraulic caliper brake includes a housing formed by two halves. A pair of bores are provided in each housing half, and a piston is positioned in each bore. An end cap closes off each bore and is sealed by an O-ring positioned around the periphery of each end cap. A ring retains each end cap within each bore. Each housing half has a pair of holes aligned with the holes of the other half. A pair of recessed areas are located on opposing ends of the housing, one of the recessed areas being positioned adjacent to one housing half and the other being positioned adjacent to the other housing half. A pair of stator plates each have a first ear with an outer shape having a flattened area positioned within one of said recessed areas in said housing, and a second ear with a continuously curved outer shape. Each ear has a hole therethrough aligned with the holes of the housing halves, and a pin is positioned in the aligned holes. An easily bleedable fluid network supplies fluid to the pistons. | 12-04-2008 |
| 20090026024 | Caliper brake system - A caliper brake system includes a housing, a bore within the housing, and a piston slidably positioned within the bore. The brake system also includes a spring assembly, a fluid chamber defined by the bore and the piston, and a hydraulic fluid supply network. The spring assembly provides a biasing force to maintain the piston in an actuated position engaging a stator which engages the rotor of a vehicle. The hydraulic fluid supply network provides pressurized fluid to the fluid chamber to selectively overcome the biasing force of the spring assembly and move the piston to an unactuated position to release the rotor. Thus, the caliper brake is spring actuated and hydraulically released. | 01-29-2009 |
| 20090095581 | Floating disc brake - A floating disc brake assembly including a housing, a pair of diametrically opposed cylindrical cavities within the housing, and an end cover positioned over the opening and having an aperture therethrough. A shaft with an axis of rotation is positioned within the aperture with an end of the shaft positioned within the housing. The shaft includes a splined surface that mates with the splined surface on the interior of a bore of a disc shaped rotor mounted on the shaft. A pair of diametrically opposed stationary liners are attached to the end cover and positioned between the end cover and the rotor. A piston is positioned within each cylindrical cavity in the housing opposed to the stationary stators, and an axially slidable piston side liner is positioned between the rotor and each of the pistons, with the rotor being axially slidable over the shaft and the pistons being biased to cause the piston side liners to force the rotor against the stationary liners to create a braking force. | 04-16-2009 |
| 20090211855 | Ball ramp brake - A ball ramp brake including a housing, a disc assembly within the housing, and an annular rotatable actuator to actuate the brake by compressing the disc assembly. The rotatable actuator includes a plurality of depressions oriented circumferentially therein which become progressively shallower in a first circumferential direction. A plurality of depressions are circumferentially oriented in a surface of the housing and become progressively shallower in a second circumferential direction. The depressions in the actuator and the depressions in the housing each have a first angle of depression that is steeper than a second angle of depression. A boot seal may be provided between the fluid chamber of an actuating cylinder and the inner area within the housing to prevent fluid leakage. In addition, a cooling chamber may be provided in the housing to improve the brakes efficiency. | 08-27-2009 |
| 20100175954 | Two-stage slave cylinder - A two-stage slave cylinder including a housing and a bore extending within the housing. An outer piston is slidably positioned within the bore in the housing, and an outer piston chamber is defined by the bore and the outer piston. The outer piston chamber is connected to a hydraulic fluid source by a fluid passageway. A biasing mechanism acts to bias the outer piston in an unactuated position unless a force is exerted on the outer piston that is greater than the biasing force. A bore is provided in the outer piston, and an inner piston is slidably positioned therein. An inner piston chamber is defined by the bore and the inner piston, and an opening is provided in the outer piston to connect the outer piston chamber to the inner piston chamber. A valve assembly is provided within the opening in the outer piston to control the flow of fluid between the outer piston chamber and the inner piston chamber. | 07-15-2010 |

| 20100019473 | Airbag system - An airbag module for a vehicle includes an airbag cushion, an inflator to inflate the airbag cushion, a sleeve connected to the airbag cushion and a tether configured to pass through the sleeve. A first end of the tether is anchored to a portion of the airbag cushion, module, or a structure of the vehicle and a second, opposite end of the tether is capable of passing through at least a portion of the sleeve during deployment of the airbag. The tether and sleeve are configured to initially restrain the deployment of the airbag cushion to provide a knee bolster, after which the tether is configured to unlace within the sleeve to release the restraint on the airbag cushion. | 01-28-2010 |
