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 system and method for calibrating and controlling an active dampening system for a chassis of a vehicle having an engine involve operating the engine in a cylinder deactivation mode and, during the cylinder deactivation mode, (i) receiving, from a set of sensors, measured vibrations on first and second frame rails of the chassis, (ii) generating control signals for a set of actuators based on the measured vibration of the first and second frame rails, each actuator being configured to generate a vibrational force in at least one direction, and (iii) outputting, to the set of actuators, the control signals, wherein receipt of the control signals cause the set of actuators to generate vibrational forces that dampen the vibration of the first and second frame rails, respectively, to decrease noise/vibration/harshness (NVH).

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.

摘要： Antivibration device comprising two frames and an elastomer body interconnecting said frames and delimiting a first hydraulic chamber linked to a second deformable hydraulic chamber via a throttle passage. A microturbine is rotatably mounted in the throttle passage and is coupled to a generator. The microturbine is configured to be always driven in the same rotational direction by the fluid when the fluid reciprocates along opposing first and second paths within the throttle passage.

摘要： A rotating body is rotatably supported on a holding section. The holding section includes a rotation detection unit, a torque-applying unit, and a brake-applying unit. The torque-applying unit includes an A-phase torque-applying coil and a B-phase torque-applying coil, and a resistance torque and a pull-in torque applied to a rotor (magnet) are caused to vary as a result of controlling supply of current to each of the coils. In addition, a braking force can be controlled by supplying current to a brake-applying coil included in the brake-applying unit.
