摘要： The present invention is a parking brake for a rail vehicle having a brake cylinder and a piston in the brake cylinder responsive to forces to apply and release the brakes on the vehicle. The parking brake further includes at least one off-center connecting rod extending though an opening in the brake cylinder and connected to the piston through that opening. The parking brake also includes a force multiplier supported by the brake cylinder and connected to the at least one off-center connecting rod. Further included is an actuator connected to the force multiplier for driving the force multiplier to provide the force to move the at least one rod and the piston to move the brakes to an apply position.

摘要： An overload protection device for a truck-mounted railcar brake assembly, comprising a body member having a first end, a second end, and at least one cavity of a predetermined size and shape disposed within the body member. A compression member of a predetermined size, shape, material, and load rating is compressed to a predetermined initial load and disposed within the cavity of the body member. A first means is secured to and disposed on the first end of the body member for engagement with a portion of a brake assembly. A second means is disposed on the second end of the body member for attaching to a force-transmitting member. A first portion of the second means is engageable with the compression member for transmitting an excess force generated from such railcar brake assembly to the compression member, whereby the overload protection device will compensate for a potential railcar brake overload condition.

摘要： An articulated railcar has several well car units for carrying shipping containers, highways trailers, or a combination of the two. The well car units permit the nose of a long highway trailer to overhang the articulated connection between two adjacent cars. A brake valve is located in a relief formed in the main bolster of one of the articulated units, out of the way of the overhanging trailer. Each well car unit has a side beam having a roll formed top chord reinforced by a top chord plate, a downwardly extending web, and a lower sill formed of a thick angle. The service, or auxiliary, and emergency brake reservoirs are mounted in a saddle bag configuration to the outside face of the webs of the opposite side beams of the articulated unit, tucked underneath the reinforced roll formed top chord.

摘要： A hydraulic parking brake assembly for a railroad vehicle braking system is provided for an automatic application of the parking brake in the absence of an air source. The hydraulic parking brake assembly comprises a hydraulic actuator having a hydraulic piston and a spindle. The spindle is capable of entering a hole provided in the back surface of a pneumatic cylinder of the railroad vehicle braking system. Upon the application of hydraulic fluid within the hydraulic actuator, the hydraulic piston and spindle move in a forwardly direction, causing the spindle to contact the piston within the pneumatic cylinder and apply a force to this pneumatic piston as if pneumatic pressure were applied within the pneumatic cylinder. Such application of force to the pneumatic piston initiates a braking sequence to achieve application of the parking brake to the railroad vehicle eliminating the need to manually apply the parking brake with a hand wheel.

摘要： A power source activated handbrake release mechanism for automatically releasing a parking brake assembly for a railroad vehicle braking system is provided. The power source activated handbrake release mechanism includes a hydraulically or pneumatically activated piston assembly including a piston rod mounted for movement upon activation of a piston within the piston assembly. An elongated member is associated at one end with this piston rod such that it moves laterally with respect to a bottom surface of the piston rod upon vertical movement of this piston rod. Another end of the elongated member is secured with the release shaft of the handbrake such that the lateral movement of the elongated member results in a rotational force being applied to the release shaft causing the automatic release of the handbrake. A system is also provided which allows the quick release handle of the handbrake to remain stationary during application of a rotational force to the release shaft via the power source activated handbrake release mechanism of the invention while maintaining the ability for an operator to manually release the handbrake with this handle should a power source be unavailable.
