POWER TAKE-OFF UNIT HOUSING HAVING INTEGRAL HYDRAULIC MANIFOLD |
摘要 |
<p>A power take-off unit and hydraulic control system includes an external manifold having a plurality of internal passageways formed therein. Pressurized fluid from a source is supplied to an input port provided on the manifold. A solenoid valve is mounted on the manifold and is selectively operable in a first and second mode modes to control the flow of pressurized fluid therethrough to a clutch actuation port of the power take-off unit. Low pressure fluid is supplied from a low pressure port of the manifold to the power take-off unit so as to provide internal lubricating fluid thereto. A temperature switch and a pressure switch may also be mounted directly on the manifold. A bracket or other mechanism may be provided to mount the manifold on a support surface, such as on a side rail of a frame assembly for the vehicle. Alternatively, the plurality of internal passageways may be formed within a housing for the power take-off unit. Thus, the solenoid valve, the temperature switch, and the pressure switch are all mounted directed on the housing of the power take-off unit, and no external mounting bracket or other mechanism is required.</p> |
