  2. GM 8L transmission - Wikipedia

    en.wikipedia.org/wiki/GM_8L_transmission

    The 8L 90 is the first 8-speed automatic transmission built by General Motors. It was debuting in 2014 and is designed for use in longitudinal engine applications either attached to the front-located engine [3] with a standard bell housing or in the rear of the car adjacent to the differential (as in the Corvette). It is a hydraulic (hydramatic ...

    en.wikipedia.org/wiki/Hydraulic_motor

    The hydraulic motor is the rotary counterpart of the hydraulic cylinder as a linear actuator. Most broadly, the category of devices called hydraulic motors has sometimes included those that run on hydropower (namely, water engines and water motors) but in today's terminology the name usually refers more specifically to motors that use hydraulic ...

    en.wikipedia.org/wiki/GM_4L80-E_transmission

    The 4L80-E (and similar 4L85-E) is a series of automatic transmissions from General Motors. Designed for longitudinal engine configurations, the series included 4 forward gears. It was the 4-speed electronically commanded evolution of the 3-speed Turbo-Hydramatic 400, first produced in October 1963. 4L80-Es were optioned only in Chevrolet/GMC ...

  6. 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]

  9. Fluid power - Wikipedia

    en.wikipedia.org/wiki/Fluid_power

    A fluid power system has a pump driven by a prime mover (such as an electric motor or internal combustion engine) that converts mechanical energy into fluid energy, Pressurized fluid is controlled and directed by valves into an actuator device such as a hydraulic cylinder or pneumatic cylinder, to provide linear motion, or a hydraulic motor or pneumatic motor, to provide rotary motion or torque.
