摘要： A mechanism (19 or 200) disposed in a torque converter housing (24) for damping torsionals in a vehicle driveline. The mechanism (19) comprises a viscous coupling (22) including a housing (64) having two sidewalls (24a, 68) defining a chamber (70) containing a viscous liquid, and a clutch member (72) disposed in the chamber for viscous clutching coaction with the housing. One of the sidewalls (24a) is defined by an end wall of the torque converter housing. The housing and clutch member are interconnected by a spring assembly (20) including flat torsion springs (61, 62) which transmit steady-state driveline torque and isolate driveline torsionals. The inner surfaces (24b, 68a) of housing (64) each include two circumferentially spaced clutching surfaces separated by the clutch member. The clutch member has oppositely facing surfaces (72b, 72c) each which include two flat circumferentially spaced clutching surfaces. When the clutching surfaces of the housing are disposed opposite the clutching surfaces of the clutch member, the clutching coaction therebetween is a maximum. When the clutching surfaces of the housing are disposed opposite the spaces between the clutching surfaces of the clutch member, the clutching coaction is a minimum. Mechanism (200) differs from mechanism (19) mainly with respect to the clutching surfaces and the position of the spring assemblies. Mechanism (19) has flat clutching surfaces, and the spring assembly is external of the viscous coupling, whereas mechanism (200) has annular rings defining the clutching surfaces, and the spring assembly is internal of the viscous coupling.

摘要： A temperature responsive viscous drive coupling having a working chamber which substantially conforms to the rotor. The coupling has a housing which defines a central cavity divided by a plate into a reservoir and a working chamber. A rotor is rotatably supported relative to the housing and located within the working chamber. The housing and the plate closely conform to the configuration of the rotor to reduce to a minimum the space within the working chamber surrounding the rotor. Dimensions are maintained between the plate and the rotor and the housing and the rotor which are generally no greater than fifty to seventy thousands of an inch. These dimensions are within acceptable manufacturing tolerances to insure that rubbing does not occur between the rotor and the housing or the plate. In such an arrangement, the volume of the fluid in the working chamber when the coupling is in the static condition will be about one-third or less than the total volume of fluid within the coupling. The disclosure results in an increase in torque capacity and a substantial decrease in the time required to pump fluid out of the working chamber into the reservoir during start up.
摘要翻译： 具有基本上符合转子的工作室的温度敏感粘性驱动联轴器。 联轴器具有壳体，该壳体将中心空腔划分成储存器和工作室。 转子相对于壳体可旋转地支撑并且位于工作室内。 壳体和板与转子的结构紧密地一致，以减小围绕转子的工作室内的空间。 在板和转子之间以及通常不超过五十到七十英寸的壳体和转子之间保持尺寸。 这些尺寸在可接受的制造公差内，以确保在转子和壳体或板之间不发生摩擦。 在这种布置中，当联接器处于静止状态时，工作室中的流体体积将约为联轴器内流体总体积的三分之一或更小。 本公开导致扭矩能力的增加以及在启动期间将流体从工作室泵出到储存器中所需的时间的显着减少。

摘要： A fluid coupling adapted to be attached to a pulley assembly which includes a pulley member and a hub having a set of external threads. The fluid coupling includes an output coupling member, an input coupling member rotatably disposed within a fluid chamber containing a volume of viscous fluid whereby torque is transmitted from the input coupling member to the output coupling member in response to relative rotation therebetween. The input coupling member includes an input shaft having a boss portion adjacent the rear surface of the output coupling member. The boss portion defines a set of internal threads for threaded engagement with the hub. The boss portion also defines a radial aperture and the output coupling member defines a slot disposed radially outward from the aperture and adjacent thereto. Both the aperture and the slot are adapted to receive an elongated tool such that rotating the output coupling member in either direction rotates the input coupling member and the boss portion in the same direction to thread the boss portion onto the hub during assembly, or unthread the boss portion from the hub to permit repair of either the fluid coupling or a device on which the coupling is mounted, such as the engine water pump.

摘要： A pump includes a housing with a pumping chamber, first and second check valves, and an inlet and an outlet in fluid communication with the pumping chamber through the check valves. The housing also includes a linear actuator with a pumping element located in the pumping chamber wherein actuation of the linear actuator induces the pumping element to move in the pumping chamber between the first and second check valves between a first position wherein the pump element moves toward the first check valve and generates a positive pressure in the pumping chamber with the positive pressure maintaining said first check valve closed and opening the second check valve to allow the fluid in the pumping chamber to flow to the outlet, and a second position wherein the pumping element moves away from the first check valve and reduces the pressure in the pumping chamber to allow the first check valve to open and draw in fluid from the inlet into the pumping chamber to thereby pump fluid from the pump.

摘要： A fluid coupling device is provided of the type including a rotatable input member and a relatively rotatable output member cooperating with a cover to define a fluid chamber therein. The device includes a movable valve member mounted on a valve shaft which is rotatably supported by a support insert seated within an opening in the cover. The rotational position of the valve shaft is made temperature-responsive by means of a bimetal coil having a first end connected to the valve shaft and a second end mounted relative to the cover. The bimetal coil has a nominal width over the major portion of its length but includes an initial portion adjacent the first end having a width substantially less than the nominal width. The initial portion comprises between about one and one and one-half turns of the coil to permit the coil to be disposed closer to the cover without interfering with the support insert.

摘要： A fluid coupling device of the type including a rotatable input coupling member, a cover associated therewith to define a fluid chamber, a valve plate separating the fluid chamber into an operating chamber and a reservoir chamber, and an output coupling member disposed in the operating chamber and rotatable relative to the input coupling member. The valve plate defines a discharge orifice permitting the flow of fluid from the operating chamber to the reservoir chamber and a generally flat valve member is located within the reservoir chamber and disposed to move in a plane substantially parallel to the plane of the valve plate to vary the flow area of the discharge orifice. The movement of the valve member defines a valve operating area and the cover includes a portion coextensive with the valve operating area and oriented substantially parallel to the plane of movement of the valve member. The cover portion is closely spaced from the valve member during movement thereof to prevent "blowoff" of the portion of the valve member adjacent the discharge orifice as fluid flows from the operating chamber to the reservoir chamber.

摘要： A viscous shear overrunning clutch having a housing and circular member is disclosed which provides a driving force in one direction and an overrunning clutch when the relative angular velocities of the clutch and housing are reversed. The design includes a housing having a circular member mounted therein. In one embodiment, spaced radially extending passageways are circumferentially defined in the circular member and allow fluid communication between a working chamber and a reservoir. Flow directing means are located on the outer periphery of the circular member adjacent the end of the radially extending passages to create pressures within the passages to move fluid between the working chamber and reservoir in response to differences in angular velocity between the housing member and circular member.

摘要： A fluid coupling device is disclosed of the type including a valve member actuated by a valve shaft extending through the cover, the position of the valve and valve shaft being controlled by a temperature responsive bimetal coil. The coil has a first end attached to the valve shaft and a second end received within a clip member to prevent circumferential movement of the second end of the coil. The clip member includes wing portions which are generally parallel to the adjacent surface of the cover. After the clip and the bimetal coil are assembled, the coil is permitted to achieve its neutral position in both the radial and circumferential direction, and subsequently, each of the wing portions is attached to the adjacent portion of the cover without causing substantial radial or circumferential movement of the second end of the coil. As a result, the coil is able to withstand extreme vibration conditions, but is not subject to the high hysteresis which normally occurs with a rigid mounting of the coil.
