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 ...
For example, in Generation 1 and Generation 2 HSDs maximum speed is mainly limited by the speed of the smaller electric motor (often functioning as a generator). The Generation 3 HSD separates the ICE-MG1 path from the MG2 path, each with its own, tailored gear ratio (1.1:1 and 2.5:1, respectively, for late Priuses, including the Prius c).
In a series hydraulic hybrid vehicle, the pump/motor directly connects to the driveshaft, [5] or the in-wheel motors provide driving torque directly to the wheel. The internal combustion engine is only connected to a pump, and is set to operate in its most efficient power range to maintain the optimal hydraulic pressure in the accumulator. [ 3 ]
The stall speed is defined as the highest speed at which the pump can turn when the output turbine is locked and full input torque (at the stall speed) is applied. Under stall conditions all of the engine's power at that speed would be dissipated in the fluid coupling as heat, possibly leading to damage.
A 3-speed light-duty version of the Turbo Hydra-Matic, called the Turbo-Hydramatic 180 was produced by GM's Hydra-Matic division from 1981 to 1998 for use in a wide variety of small cars and trucks. Hydramatic is a trade name for GM's automatic transmission division, which produces a variety of transmissions, the most notable of which is the ...
The powerplant used in Saturn S-Series automobiles was a straight-4 aluminum piston engine produced by Saturn, a subsidiary of General Motors.The engine was only used in the Saturn S-series line of vehicles (SL, SC, SW) from 1991 through 2002.
