    摘要: A switchable hydraulic bearing for mounting of a motor-vehicle assembly comprises a support bearing and a mount connected by a support spring, and a working chamber and an equalization chamber fillable with damping liquid that are spatially separated by a separating wall and connected by a damping channel in the separating wall. The separating wall may comprise a nozzle cage with two adjacent nozzle discs provided with an axial spacing. A diaphragm of rubber-elastic material may be provided in a gap between the nozzle discs. The diaphragm may be switchable by a switching device comprising an elastic lever disc axially adjacent to the second nozzle disc. An electromagnet may connect to the lever disc and can adjust the lever disc between a first position, permitting axial play of the diaphragm in the gap, and a second position, acting on the second nozzle disc and clamping the diaphragm between nozzle discs.

    摘要: A hydraulic mount assembly includes a mount body defining a cavity. A powertrain includes a dynamic mass, and a structure that supports the dynamic mass. The assembly is attached to the structure and supports the dynamic mass. A first plate is fixed relative to the mount body inside the cavity to separate the cavity into a first chamber and a second chamber. The first plate defines a plurality of first passages that fluidly connects the first and second chambers. A decoupler is disposed between the first and second chambers. An actuator is coupled to the first plate. The decoupler is movable in response to actuation of the actuator. The decoupler abuts the first plate when in a locked position to prevent fluid communication through the first passages. The decoupler is movable relative to the first plate when in an unlocked position to allow fluid communication through the first passages.

    摘要: A method includes determining whether a multiphase electric machine is unstable. The method also includes, in response to a determination that the multiphase electric machine is unstable, setting a gate voltage of a first three terminal semiconductor switch to zero. The method also includes, in response to a determination that the multiphase electric machine is stable, setting the gate voltage of the first three terminal semiconductor switch to nonzero. The method also includes, in response to the first three terminal semiconductor switch being set to zero, increasing electrical conduction from one phase of the multiphase electric machine to another phase of the multiphase electric machine. The method includes, in response to the first three terminal semiconductor switch being set to nonzero, increasing electrical resistance from the one phase of the multiphase electric machine to the another phase of the multiphase electric machine.

    摘要: A system and method using a mount assembly for attaching a powertrain to a structural member of a vehicle. The mount assembly includes a first compliant member, a second compliant member, a first fluid chamber, a second fluid chamber, a third fluid chamber, a pressure compliant membrane, and a valve. A fluid conduit interconnects the first fluid chamber with the second fluid chamber to allow a fluid to pass from the first fluid chamber to the second fluid chamber. The third fluid chamber has an opening in communication with the second fluid chamber and a vent port. The pressure compliant membrane seals the opening between the second fluid chamber and the third fluid chamber. The valve selectively seals the vent port in the third fluid chamber. A first stiffness profile of the mount assembly is selected by actuating the valve to open the vent port. A second stiffness profile of the mount assembly is selected by actuating the valve to close the vent port.

    摘要: A hydromount for mounting a motor vehicle unit is disclosed. The hydromount includes a supporting spring supporting a mount core and surrounding a working chamber, and a compensation chamber separated from the working chamber by a dividing wall and delimited by a compensation diaphragm. In embodiments, the compensation chamber and the working chamber are filled with a liquid and are connected by a damping duct incorporated into the dividing wall. In an embodiment, the dividing wall has two dividing plates between which a diaphragm is accommodated in a manner capable of oscillating. In an embodiment, the diaphragm and the dividing wall delimit an air chamber connected to the environment via an opening in the dividing wall, and the opening can be unblocked and closed by a switchable non-return device having a pressure-actuatable non-return valve with an opening pressure set to or having an oscillation amplitude of the diaphragm.
