Abstract: An active damping system for an electric motor driven vehicle having spaced apart front wheels coupled to the vehicle by suspension components, includes a first sensor, a first actuator and a controller. The first sensor is coupled to one or both of a first front wheel or a suspension assembly for the first front wheel, and the first sensor provides an output indicative of a force on a component to which the first sensor is coupled. The first actuator is coupled to the vehicle and has a movable mass driven by the first actuator. The controller is configured to receive the output from the first sensor and the controller is configured, in response to at least an output from the first sensor that is beyond a threshold, to provide an output to the first actuator to displace the movable mass and at least partially damp vibrations in the vehicle.

Abstract: A powertrain component mount includes a housing, a main rubber element, a hydraulic body, a membrane and a valve. The main rubber element has an outer armature, an inner armature and an isolating element coupled to the armatures, the isolating element being formed of a material that is more flexible than the outer armature and the inner armature, wherein the main rubber element defines at least part of a fluid flow path. The hydraulic body supports the outer armature of the main rubber element, defines part of the fluid flow path, a fluid chamber, and part of a control chamber communicated with the fluid flow path. The hydraulic body has a port open to the control chamber. The membrane defines part of the control chamber and the valve has a valve head movable between a first position closing the port and a second position spaced from the port.

Abstract: A mount to couple a transmission to a vehicle body includes a first body with at least one first body connector, and a second body with at least one coupler connected to the first body and which includes a damping material arranged to damp vibrations between the first body and second body. A retainer is carried by the first body and has a portion that overlaps part of the second body to prevent separation of the second body from the first body in a first state of the retainer. The retainer is broken or removed from the first body in a second state to permit separation of the second body from the first body, and the retainer breaks or is removed from the first body under a force less than the force needed to break or remove the at least one first body connector from the vehicle body.

Abstract: 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).

Abstract: In at least some implementations, a bracket for mounting a drivetrain component to a vehicle, includes a first extruded section having a first connection element, and a second extruded section having a second connection element, where the first connection element is mated with the second connection element. The first extruded section and the second extruded section are press-fitted together with a load-bearing interference fit between the first connection element and the second connection element.

Abstract: Bolt retention threads are provided adjacent the proximal end of the body coupling aperture of a body isolator. A bolt has cooperating bolt retention threads and body coupling threads on the shaft. These body coupling threads have a diameter to permit the external body coupling threads to pass through the internal bolt retention threads without requiring threaded engagement therebetween. The cooperating bolt retention threads are axially positioned relative to each other to enable the entirety of the external bolt retention threads to be threaded completely through the internal bolt retention threads to capture the bolt within the body coupling aperture in a captured floating configuration. In the captured floating configuration, the external body coupling threads and the distal end of the shaft extend out of the distal end of the body coupling aperture and the bolt is allowed to float laterally within the body coupling aperture.
