摘要： A friction brake mechanism having a pair of front brake assemblies and a pair of rear brake assemblies receives pressurized fluid at the same time and at the same pressure from a hydraulic control apparatus. Each of the brake assemblies has a brake piston movable in a chamber between a holding position and a releasing position and a plurality of brake plates and a plurality of brake disks interleaved with the brake plates. A first spring system is associated with the pair of front brake assemblies and a second spring system is associated with the rear brake assemblies. The first spring system provides a different force than the second spring system to cause the rear brake assemblies to be engaged a predetermined period of time ahead of the pair of front brake assemblies without any design change in the hydraulic control apparatus.

摘要： An electrically-controlled fluid pressure responsive brake system, in which a solenoid valve is installed between a manual brake valve and a parking brake. The parking brake is equipped with a spring actuator. The solenoid valve can be positioned by an electronic system into an open position only when an ignition switch has been turned on and the brake system has been successfully tested by the electronic system. The test can be initiated by pressing the brake pedal all the way to the floor. The solenoid valve allows the release of the parking brake only if the brake system is intact.

摘要： A hydraulically-actuated brake system for off-road, heavy vehicles that includes separate accumulators for braking the front and rear brakes and brake valves that are both manual and pilot actuated for controlling the flow of hydraulic fluid from the accumulators to the brakes. Also included are valves for comparing the pressure in the front and rear accumulators so that, should one of the systems become low, the brakes are immediately set. Also included is a manual valve for overriding the brake valves in the event that a malfunction occurs in one of the brake valves.

摘要： In a brake valve of the type in which a given ratio is maintained between a master pressure developed by a brake pedal and an actual brake pressure, an arrangement is provided for continuous, rather than stepwise, adjustment of this ratio. The brake valve includes a control piston which is subjected to the master pressure and which, by the displacement thereof, opens and closes connecting channels between an accumulator containing a primary pressure fluid and a brake, as well as between the brake and a fluid collecting tank. The control piston and a measurement piston apply counter forces to the arms of a balance beam whose lever ratio determines the degree of feedback of the instantaneous brake pressure to the control piston. A stop is provided in the path of the axis of the control piston, which limits the stroke of the piston, to prevent the overloading of the balance beam during abnormally high braking pressures such as occur, for instance, during panic braking.

摘要： An unwind stand for positioning and controlling the unwinding of large paper rolls to processing machines is mounted on wheels riding on rails and motor driven through hydraulic motor to providing gripping and longitudinal movement of the rolls. Swinging gripping arms are mounted on the stand and disposed to grip the ends of the roll and raise it above the floor and hold it in position and provides for unwinding. The arms are capable of longitudinal movement along the axis of the roll, either individually or simultaneously, for flexibility in picking up the roll and locating it into operating position. A device is provided for final axial adjustment in alignment with the processing machine in a transverse direction and a device for gripping the rails to hold the machine in a fixed position and to prevent its tipping over. The entire stand and all its functioning elements is operated from a platform located on a cab in which are positioned various control elements for operation of the hydraulic components of the stand.

摘要： The invention is directed to a fail-safe brake arrangement for hydraulically powered road rollers. The operating means of the brake system are completely separate from the normal road brake of the roller thereby enabling the fail-safe brake to be manually operated by the driver in an emergency situation. The brake also operates automatically as soon as the hydraulic system of the roller ceases to function. The fail-safe brake according to the invention utilizes the oil pressure to compress one or more springs in a spring brake chamber. As soon as the oil pressure falls to zero or below a certain value, the energy stored in the springs is utilized to apply the brake and bring the vehicle to a halt.

摘要： A hydrostatic transmission has an engine-driven, bidirectional, variable-displacement drive pump connected in circuit with a bidirectional, variable-displacement propelling motor. A charging pump is also connected to the circuit of the drive pump and the propelling motor. A brake assembly normally locks the output shaft of the propelling motor against rotation and releases same only while being supplied with a hydraulic brake release signal. The control system for the hydrostatic transmission comprises a speed control valve actuated manually to deliver fluid pressure signals to servo controls for adjusting the outputs from the drive pump and the propelling motor, and a brake control valve pilot-operated to deliver the brake release signal to the brake assembly. Also included are a charge sensor valve and a speed control sensor valve. The two sensor valves cooperate to cause the output from the charging pump to pilot-actuate the brake control valve, for the delivery of the brake release signal, only when the charging pump output pressure rises to a predetermined level and, simultaneously, when the speed control valve is being manipulated. Whenever the charging pump output pressure falls below the predetermined level, the sensor valves cause the brake control valve to terminate the production of the brake release signal and to drain the signal output ports of the speed control valve, thereby causing the transmission to stop the vehicle and so avoiding cavitation in the drive pump and the propelling motor.
