摘要:
A liquid friction clutch (1) having a housing (2, 3), a clutch disc (4) rotatable relative to the housing (2, 3) and which is rotatably arranged on an end (5) of a shaft (6) which is mounted centrally within the housing (2, 3), which shaft (6) bears on its other end (8) a driveable active element (7). A working chamber (9) is positioned between the housing (2, 3) and the clutch disk (4). A storage chamber (10) is provided for the clutch fluid. A supply duct (11) leads from the storage chamber (10) to the working chamber (9). A stationary clutch part (13) relative to which the housing (2, 3) is rotatable, wherein a rotatably mounted pump element (14) is provided which, with the housing (2, 3), defines a shear gap (12).
摘要:
A blow molding tool (1) for producing a plastic article, in particular a fuel tank, comprising at least one clamping frame (2) with mold clamping devices (3) and at least two blow mold halves, which are formed such that they can be moved together and apart by means of an opening and closing movement of the clamping frame (2) and which respectively have at least one cavity (8) for the forming of the plastic article, the blow molding tool (1) being distinguished by the fact that the mold clamping devices (3) respectively have at least one tool holder (6), in which a mold insert (7) is in each case exchangeably inserted, and in that the tool holders (6) respectively form a peripheral sealing edge (10).
摘要:
A fluid friction clutch with improved fluid pumping system. A scraping member is provided adjacent the clutch plate and has a duct which communicates with the reservoir chamber.
摘要:
A control system for a fan of a cooling system of an internal combustion engine of a motor vehicle having a viscous coupling (fan clutch) driving the fan and a control unit (PID governor) to which the setpoint temperature and the measured actual temperature of the cooling system (coolant temperature) are fed. The control unit (PID governor) is connected downstream to a limiter, which holds the ratio of output speed to input speed below a specifiable limit (x % of input speed). An overheat protection logic disables the limiter when the actual coolant temperature exceeds a specifiable critical temperature that is higher than the setpoint temperature of the control unit (PID governor).
摘要:
Regulating the rotational speed of the driven rotor of a viscosity coupling to a predetermined speed with a control circuit having a switching mechanism. When the speed drops below certain values, the speed is adjusted back to the predetermined value.
摘要:
A method and materials are disclosed wherein a layer of a softer thermoplastic material comprising (i) a thermoplastic polyurethane or (ii) a thermoplastic elastomer alloy including a styrenic thermoplastic elastomer and a thermoplastic polyurethane can be attached to a substrate comprising a harder thermoplastic alloy including a polyester and a polycarbonate. In one form, the method and materials are used to form a modular chain link for use in constructing a modular conveyor chain. The modular chain link includes a main body comprising the thermoplastic alloy including a polyester and a polycarbonate, and a softer layer of the thermoplastic material comprising (i) a thermoplastic polyurethane or (ii) a thermoplastic elastomer alloy including a styrenic thermoplastic elastomer and a thermoplastic polyurethane disposed on at least a portion of the main body.
