  • Patent number: 11396868
    Abstract: A pumping system utilizes a linear actuator to move a shaft attached to two pistons within cylinders to pump a working fluid. A housing is designed with coolant passageways and one-way valves such that movement of the shaft also pumps coolant past cooling fins and over a motor. The shaft is formed of several sections joined by couplers which slide within a bore of the housing. The couplers have a non-round shape and the bore has a complimentary non-round cross section such that rotation of the shaft is prevented.

    Abstract: A motor vehicle pump arrangement has a first pump and a second pump, and an electric motor for driving the two pumps. The electric motor is drive-connected fixedly to the first pump and connected via a clutch arrangement to the second pump, in such a way that the first pump can be driven on its own and the first and second pump can be driven together. The first pump is configured as a reversible pump which can be operated in two rotational directions. A valve arrangement generates a uniformly directed fluid volumetric flow which is independent of the rotational direction being provided for the first pump in a fluid circuit. The clutch arrangement is configured as a freewheeling clutch, via which the electric motor is drive-connected to the second pump.

  • Patent number: 11149798
    Abstract: A rotary clutch uses a wrap spring clutch. An actuator generates a drag force to control the wrap spring clutch to engage or disengage the clutch. The actuator includes an electromagnet, a two-component armature and an axial return spring. The two-component armature includes first and second components threadingly connected one another for relative axial translation as they rotate relative to one another, and an angular position biasing member connecting them. The second component translates axially under magnetic force from the electromagnet, and when stopped by the electromagnet the first armature component translates axially due to their threaded connection. Due to the previous axial movement of the floating component the translation of the first armature component occurs in conditions where the air gap and reluctance of a magnetic circuit is reduced compared to the prior art, and thus the overall strength of the applied magnetic field can be comparatively reduced.

  • Patent number: 8764411
    Abstract: Methods and systems are provided for pressurizing a transmission hydraulic circuit including a transmission mechanical pump coupled to an engine though a gearbox. One example method comprises, during an engine start, adjusting a speed ratio between the transmission pump and the engine between a first speed ratio and a second speed ratio, the pump rotating faster relative to the engine at the first speed ratio as compared with the second speed ratio. In this way, the pump may be driven at different speed ratios relative to the engine to provide better pressurization in the transmission.

  • Publication number: 20140140864
    Abstract: An arrangement for selectively making available hydraulic power in separate hydraulic circuits comprises two displacement machines, two free-wheels and a drive unit that is preferably arranged between the displacement machines. The free-wheels block in opposite directions and are coupled to the displacement machines. Consequently, the first displacement machine is driven in a first rotating direction of the drive unit while the second displacement machine is only driven in a second, opposite rotating direction of the drive unit. This makes it possible to realize an intermittent operation for selectively making available additional hydraulic power in separate hydraulic subsystems by choosing the rotating direction accordingly. This arrangement can reduce the weight and the complexity of a hydraulic system.

  • Patent number: 8714939
    Abstract: A water pump includes a housing, a pumping mechanism, and a pulley that receives an input torque. Rotation of a clutch disk provides a rotational force to the pumping mechanism. A ferromagnetic clutch ring rotates in unison with the pulley. The clutch ring moves between a disengaged position and an engaged position to selectively rotate the clutch disk in response to the input torque. A magnet disposed on the clutch disk attracts the clutch ring toward the engaged position, and an electromagnetic coil is operable to selectively diminish the attraction of the clutch ring to the magnet to move the clutch ring between the engaged and disengaged positions.

  • Patent number: 8690546
    Abstract: An auxiliary drive system for a water pump includes a pump housing that is mounted to an engine block. The pump housing includes an impeller shaft that passes therethrough. One end of the impeller shaft has an impeller mounted thereon, which is part of the water pump. A second end of the impeller shaft is supported by an internal bearing to allow for rotation of the impeller shaft. An external bearing is disposed around, but not in contact with the impeller shaft or the internal bearing. The external bearing is in communication with and is driven by an engine belt, such as a timing belt, which helps rotate the impeller shaft and the impeller in accordance with engine operation. A collapsible gear is disposed between and effectuates engagement of the external bearing and the impeller shaft such that if the amount of force required to be exerted by the belt exceeds a certain predetermined threshold, the collapsible gear fails and thereby prevents damage to the engine.
