20090101451 | Force Measuring Device for a Parking Brake of a Vehicle, in Particular of a Passenger Vehicle - A force measuring device for a parking brake of a vehicle has a housing, having a Bowden cable for actuating the parking brake and having a force measuring element for determining the cable force. The Bowden cable is guided through the housing and has first and second stops which are fastened to the Bowden cable, wherein under loading of the Bowden cable, the first stop is fixedly supported on a housing inner side and the opposite, second stop is supported on the force measuring element which is provided between the housing and the second stop, wherein a movement of the second stop is generated corresponding to the loading of the Bowden cable, which movement leads, at the force measuring element, to a corresponding measurement value for the force transmitted by the Bowden cable. The force measuring device is provided for parking brakes for passenger vehicles. | 04-23-2009 |
20110056774 | BRAKE SENSOR APPARATUS FOR BICYCLES - A brake sensor apparatus is provided, including a base unit, a movement unit, a spring, a first buckle unit and a second buckle unit. The movement unit is partially confined inside the base unit so that the movement of the movement unit is restricted to a short distance and along the direction of the base unit. The spring is to allow the retracted movement unit to be moved to the original position. The first buckle unit and the second buckle unit are engaged respectively to the outer wall of base unit and movement unit, and can be hanged and buckled to the positions of brake wire of the brake. In this manner, when the bicycle brakes, the movement unit is retracted into the base unit so as to trigger the trigger switch to connect the connected circuit. | 03-10-2011 |
20110094833 | METHODS AND APPARATUS FOR MANAGING PRESSURIZED GAS IN FLUID DAMPERS - A method and apparatus for a shock absorber having a damping fluid compensation chamber with a gas charge. In one aspect, a partition separates a first chamber portion from a second chamber portion, wherein the first portion of the chamber is at a first initial gas pressure and the second portion of the chamber is at a second initial pressure. A valve separates the first and second chamber portions and opening the valve commingles the first and second chamber portions so that the combined chamber portions are at a third pressure. In another aspect, a piston disposed through a wall is in pressure communication with the gas charge and is biased inwardly toward a pressure of the charge, whereby an indicator is movable by the piston in response to the pressure. | 04-28-2011 |
20110308897 | ELECTRONIC STROKE SENSOR FOR AIR DISC BRAKE - A vehicle brake monitor assembly for an air disk brake includes a brake actuator having a pushrod projecting from inside a chamber of said brake actuator. The pushrod releasably actuates a lever arm of a caliper thereby moving the disk brake into a braking position when the pushrod is in an extended position and releasing the disk brake from the braking position when the pushrod is in a retracted position. The pushrod includes a pushrod shaft and a contact member biased in a telescoping relationship relative to the pushrod shaft and the lever arm of the caliper abuts the contact member counteracting the bias of the contact member. A sensor is integrated with the assembly proximate the contact member and detects movement of the pushrod relative to the lever arm and to the pushrod shaft. | 12-22-2011 |
20120132488 | Brake Monitoring Device For A Disc Brake - A brake monitoring device for sensing a value which reflects the actuation and/or release stroke of a thrust element of a brake actuating mechanism, which thrust element is guided in a housing of a brake caliper. The thrust element acts via a brake lining onto a brake disc by a lever. A sensor is configured to detect variations of a physical quantity at least one component of the brake actuating mechanism. The sensor and component are arranged such that relative movement between them generates constantly repeating variations of the physical quantity along a path. The path is formed between the component of the thrust element and the sensor in axial direction of the thrust element by means of a linear extension from the end of the thrust element facing the brake disc, axially away from the brake disc. | 05-31-2012 |
20120205200 | DEVICE AND METHOD FOR SENSING APPLIED CONDITION OF A RAILROAD HANDBRAKE - A device for indirectly sensing tension of a chain in a railroad handbrake includes an elongated bore formed through a holding pawl of the handbrake, sensor target attached to the holding pawl and a sensor mounted in close proximity to an upper end of the housing so as to sense the sensor target. The ratchet wheel of the handbrake positions the sensor target for operative sensing alignment with the sensor during at least partial handbrake application. A biasing member moves the sensor target away from the operative sensing alignment during handbrake release. | 08-16-2012 |

20140116812 | SAFETY VALVE FOR TRAILER - A device and method to override a conventional trailer emergency brake system that may include a safety valve to override the brake valve located in a tractor. A preferred safety valve may be located in a sidewall of a trailer. In one position, a preferred safety valve may prevent compressed air from being transmitted to the trailer parking brakes so that a truck driver is unable to release the trailer brakes. In another position, a preferred safety valve may divert compressed air to one or more devices to alert a driver, a dock worker or others of an effort to release the trailer parking brakes. In another position, a preferred safety valve may permit compressed air to be transmitted so that a truck driver is able to release the trailer brakes. | 05-01-2014 |
20140144728 | BRAKE TORQUE SENSING SYSTEM - The invention includes a system and method for controlling a brake system for a motor vehicle. The system determines actual brake torque by measuring the strain in an elongated portion of a suspension knuckle, the elongated portion being attached to a brake caliper which engages a disc brake to create the actual brake torque. The system can use the determined actual brake torque to best apply a proper blend of brake torques between the caliper and disk brake and a regenerative braking system through a closed loop analysis method. | 05-29-2014 |
20140318903 | SAFETY VALVE FOR TRAILER - Systems and methods of overriding a conventional trailer emergency brake system to preclude and alert others as to inadvertent or premature movement of the trailer are described herein. One implementation includes a safety valve operatively positioned in the emergency braking system of a trailer that may be engaged to override the brake valve located in a tractor to prevent a truck driver from prematurely or inadvertently moving the trailer. In addition, the system may include a one way check valve to allow hydraulic fluid upstream of the safety valve to bleed out of the brake system when the safety valve is closed (to prevent movement of the trailer) before the emergency brakes for the trailer are set by the driver. A communication system may also be provided to alert the driver via a remotely located computing device that the emergency brakes for the trailer need to be set. | 10-30-2014 |
20160102723 | BRAKE WITH AUDIBLE LOCK-UP WARNING - The present invention provides a braking system that is designed to give the rider of a vehicle an audible indication of an impending lock-up condition (i.e., a condition where the wheel of a wheeled vehicle or track or a snowmobile is not rotating relative to the vehicle). Preferably, the frequency of the audible indication is proportional to the speed of the wheel or track. In one embodiment, the characteristics of the sound (e.g., frequency) are tuned to achieve an audible indication that can be readily heard and perceived by a rider under specific conditions, such as when the rider is wearing a helmet and also in the presence of other noise, such as engine and exhaust noise. In general, an audible indication in the range of about 6 kHz+/−1 kHz is preferred. The audible indication can be altered by changing the geometry and dimensions of the brake rotor and brake pads. | 04-14-2016 |
