HYDRAULIC HYBRID TRANSMISSION RETARD DEVICE

摘要

A retard device (100, 100') for a hybrid system (2) is provided. The retard device (100, 100') includes a housing (102, 102') having a first end (104, 104') and a second end (106, 106'). The first end (104, 104') has a system inlet (108, 108') and the second end (106, 106') has an aperture (110, 110'). A piston assembly (112, 112') is slidably disposed in the aperture (110, 110') of the housing (102, 102'). The piston assembly (112, 112') includes a piston head (114, 114') coupled to an actuating linkage (116, 116'). The piston head (114, 114') is disposed adjacent the system inlet (108, 108') and the actuating linkage (116, 116') is disposed through the aperture (110, 110') of the housing (102, 102'). A spring (126, 126') is disposed within the housing (102, 102') between the second end (106, 106') and the piston head (114, 114'). The piston head (114, 114') is biased toward the first end (104, 104') by the spring (126, 126') and biased toward the second end (106, 106') by a force applied at the system inlet (108, 108'). A hybrid system (2) and method of using the retard device (100, 100') are also provided.
