20080258542 | FULL FUNCTION TRACTOR PROTECTION VALVE - A tractor protection valve includes a trailer service brake portion, a trailer parking brake portion, and a stability control portion that are each formed within a common valve body. In one example, the trailer service brake portion includes three inlets that can be used to apply a trailer service brake. The three inlets cooperate with a service brake blocking piston, a service brake relay piston, and double check valves to apply the trailer service brakes as needed. The stability control portion includes a solenoid that can direct air to apply the trailer service brakes in response to a stability control signal. The trailer parking brake portion also includes multiple ports that cooperate with a parking brake piston and valve to control application and release of the trailer parking brakes. | 10-23-2008 |
20090091179 | Truck/trailer brake control system - A braking system for a combined tractor-trailer assembly wherein a leading trailer is coupled to a towing tractor and a trailing trailer is coupled to the leading trailer. All of the wheels of the trailers are provided with brakes which may be applied and released in response to the operation of a brake control pedal operated by a driver in the tractor. The brakes also may be applied to the trailing trailer whenever the latter is parked. The brakes of the trailing trailer normally are maintained in applied condition by a spring assisted mechanism when such trailer is parked. Such mechanism normally is disabled by pressurized fluid when the trailer is in service and the pressured fluid is accessible via a valve which simultaneously enables the parking brakes and service brakes simultaneously to be coupled to and uncoupled from the pressure fluid system. | 04-09-2009 |
20100007200 | DECELERATION CONTROL FOR A VEHICLE - A method, a vehicle using the method, and a system using the method, of controlling the vehicle configured to tow a trailer. The method includes determining first and second vehicle parameters indicative of first and second conditions of the vehicle, and determining a trailer presence from at least one of the first and second vehicle parameters. The method also includes updating the first vehicle parameter when the trailer is present, generating a third vehicle parameter, and determining first and second braking control parameters from the first, second, and third vehicle parameters. The first braking control parameter corresponds to at least one of the second and third vehicle parameters, and the second braking control parameter correspond to at least one of the first and second vehicle parameters. The method can further include generating a braking signal based on one of the first and second braking control parameters. | 01-14-2010 |
20100019565 | ELECTRONICALLY CONTROLLED BRAKING DEVICE OF A TOWING VEHICLE-TRAILER COMBINATION - An electronically controlled braking device of a towing vehicle-trailer combination, which includes at least a generating arrangement (FBM) for generating at least one brake request signal, an electronic towing vehicle brake control unit associated with the towing vehicle for generating brake pressure setpoint value signals for at least one electro-pneumatic pressure control module of the towing vehicle as a function of the brake request signal, a data link between the towing vehicle and the trailer, at least one electro-pneumatic pressure control module associated with the trailer for controlling a trailer brake pressure, in which the data link is for direct communication between the towing vehicle brake control unit and the at least one electro-pneumatic pressure control module of the trailer, and in which the towing vehicle brake control unit and the data link are for directly inputting control signals into the at least one pressure control module of the trailer for generating the trailer brake pressure at least as a function of the brake request signal. | 01-28-2010 |
20100072809 | Convertible Wireless Display Unit - An operator interface unit, includes a housing with a first electrical port having a first pair of terminals to be connect to a pair of network wires of the locomotive, and a second pair of terminals to be connected to a power source. A display and input device are on the housing. A transceiver assembly wirelessly communications with the ECP system. A controller assembly is connected to the first electrical port, the display, the input device and the transceiver assembly, and wherein the controller assembly is a node on the network via one of the first electrical port and the transceiver assembly. A portable assembly includes a battery source in a container which irremovably houses the operator interface unit. | 03-25-2010 |

20090302674 | Front towing glad hands - A towing arrangement on a vehicle includes a pair of glad hands for receiving pressurized air and a plurality of double check valves connecting the glad hands to valves associated with a braking system of the vehicle. Air from a first glad hand is supplied through a first of the double check valves to a spring brake modulating relay valve associated with spring brakes of the vehicle. Air from a second glad hand is supplied through a second of the double check valves to a first release valve associated with service brakes of a front axle of the vehicle and through a third of the double check valves to a second release valve associated with service brakes of a rear axle of the vehicle. | 12-10-2009 |
20130175852 | HYDRAULIC DEVICE FOR CONTROLLING BRAKING IN VEHICLES WITH TWO BRAKING PEDALS - A device for controlling braking in vehicles with two braking pedals (PS, PD), such as farm tractors, earthmovers and the like, comprises a body ( | 07-11-2013 |
20150015060 | NO-DELAY OVERLAY PNEUMATIC AIR BRAKE SYSTEM - The present application relates to a braking system for a train that is configured to operate in combination with pneumatic systems. The braking system includes an electronic control board and an electronic control valve coupled to the brake pipe on a railcar. The braking system is located on one of a number of railcars dispersed throughout the train. The electronic control board monitors a brake signal from the locomotive and selectively transmits signal data to the electronic control valve to release air pressure within the brake pipe. The braking system provides one or more air release locations within the brake pipe so as to reduce braking stresses. | 01-15-2015 |
