  3. Hydraulic motor - Wikipedia

    en.wikipedia.org/wiki/Hydraulic_motor

    A hydraulic motor is a mechanical actuator that converts ... Whereas the speed of hydraulic pumps range from 1200 to 1800 rpm, the machinery to be driven by the motor ...

  4. Hydraulic hybrid vehicle - Wikipedia

    en.wikipedia.org/wiki/Hydraulic_hybrid_vehicle

    Hydraulic hybrid vehicle systems consists of four main components: the working fluid, reservoir, pump/motor (in parallel hybrid system) or in-wheel motors and pumps (in series hybrid system), and accumulator. In some systems, a hydraulic transformer is also installed for converting output flow at any pressure with a very low power loss. [3]

  5. Hydraulic machinery - Wikipedia

    en.wikipedia.org/wiki/Hydraulic_machinery

    If a hydraulic rotary pump with the displacement 10 cc/rev is connected to a hydraulic rotary motor with 100 cc/rev, the shaft torque required to drive the pump is one-tenth of the torque then available at the motor shaft, but the shaft speed (rev/min) for the motor is also only one-tenth of the pump shaft speed.

  6. Hydraulic cylinder - Wikipedia

    en.wikipedia.org/wiki/Hydraulic_cylinder

    A hydraulic cylinder is the actuator or "motor" side of this system. The "generator" side of the hydraulic system is the hydraulic pump which delivers a fixed or regulated flow of oil to the hydraulic cylinder, to move the piston. There are three types of pump widely used: hydraulic hand pump, hydraulic air pump, and hydraulic electric pump.

  7. Retarder (mechanical engineering) - Wikipedia

    en.wikipedia.org/wiki/Retarder_(mechanical...

    Retarders are not restricted to road motor vehicles, but may also be used in railway systems. The British prototype Advanced Passenger Train (APT) used hydraulic retarders to allow the high-speed train to stop in the same distance as standard lower speed trains, as a pure friction-based system was not viable.

  8. Cross-drive steering transmission - Wikipedia

    en.wikipedia.org/wiki/Cross-drive_steering...

    A later design of cross-drive transmission, the Allison X1100, was used in the 1970s experimental US MBT-70 and XM1 [3] tanks, then later adopted in the M1 Abrams.This adopts a different principle for the steering cross-coupling: instead of a hydro-dynamic torque converter, it uses a hydrostatic combination of a hydraulic pump and a hydraulic motor.

  9. Hydraulic Launch Assist - Wikipedia

    Ford Motor Company included the HLA system in their 2002 F-350 Tonka truck concept vehicle, reported to have lower emissions and better fuel economy than any V-8 diesel truck engine of the time, with HLA designed to eventually improve fuel economy by 25%-35% in heavy truck city driving. [3]
