TLDR
In this article, the condition of handbrakes on railway cars is indicated using mechanical, electrical and electronic signals, and the handbrake can operate on pneumatic or electric power provided from the service air brake system of a train or from a source of power outside of such air brake systems.Abstract:
Apparatus for indicating the condition of hand brakes on railway cars and for applying and releasing railway car parking or hand brakes automatically in response to predetermined conditions including movement of a train, wayside conditioning apparatus, wayside operating mechanism, a signal controlled by an operator and performance of predetermined railway operating procedures, such as completion of an air brake test procedure. The apparatus may respond to mechanical, electrical and electronic signals and may operate on pneumatic or electric power provided from the service air brake system of a train or from a source of power outside of such air brake system.read more

Electrohydraulic parking brake control system
TL;DR: In this article, a spring-applied, pressure-released parking brake is controlled by an electrohydraulic control system, which is adapted to use for an electronic control transmission, where a solenoid operated parking brake control valve 40 and a manually operated tow control valve 60 control communication between the engine driven pump 22, sumps 24, 24a, an operator driven pump 80 and a release chamber 12 of the parking brake so that the parking Brake 10 can be released and by operation of the operator driven Pump 80 when the vehicle is shut down.
Patent
Parking brake system for railway vehicles
TL;DR: A fluid brake system has a brake pipe, a control valve device, a brake cylinder and a brake rigging, and a manually operable handbrake device for selectively governing the brake rigging under varying conditions, such as when air supply is disconnected from a train this paper.
Patent
Automatic self-resetting parking brake
TL;DR: A parking brake with an output lever connected at a first pivot point to a brake rod, at a second pivot points to a fluid responsive actuator and at a third point to one end of a chain of a standard manual releaseable parking brake unit is described in this article.
Patent
Automatically engaged emergency parking brake
Norman J. Hodge,John W. Bridwell +1 more
TL;DR: In this article, a control system for a vehicle parking brake-actuator which releases the brake when subjected to fluid under pressure and automatically sets the brake by spring force when the fluid pressure is relieved therefrom, the actuator being controlled by a valve which blocks or allows the relief of fluid pressure from the brake actuator.
Patent
Electro-pneumatic spring and service brake actuator
TL;DR: In this article, a tandem brake system consisting of an actuateur de frein de service (12) and a parking brake actuator (16) with spring biased spring bias is described.
