Abstract: A tensioner with a bracket, a tensioner body coupled to the bracket for rotation about a first axis, a first and second wheels that are coupled to the tensioner body for rotation about second and third axes, respectively, that are parallel the first axis, and a spring that biases the second wheel along a line of action relative to the tensioner body. The second wheel is coupled to the tensioner body for movement between first and second positions along the line of action.

Abstract: A variable camshaft timing device adjusts phase between a camshaft and a crankshaft and includes a first ring gear configured to connect to the camshaft and rotate about a center axis, having a plurality of radially-inwardly facing gear teeth; a second ring gear axially spaced from the first ring gear, configured to receive rotational input from the crankshaft and rotate about the center axis, having a plurality of radially-inwardly facing gear teeth; a planetary gear assembly including one or more planet gears that are configured for rotation by an electric motor and engage the first ring gear and the second ring gear through the planet gear(s); and a cushioned stop configured to transmit energy between the planetary gear assembly and a planetary gear stop attached to a sprocket or a camshaft plate.

Abstract: A torque-limiting coupler for connecting an electric motor to a rotatable input of a vehicle is provided, including: a rigid frame that is configured to be coupled to one of the rotatable input or an output shaft of the electric motor; and an elastic member, configured to engage the other of the rotatable input or the output shaft of the electric motor, that engages the rigid frame such that the elastic member substantially maintains its shape and inhibits angular displacement between the rotatable input and the output shaft when an amount of torque received from the output shaft is below a predetermined torque limit, the elastic member changes shape permitting angular displacement between the rotatable input and the output shaft when an amount of torque received from the output shaft exceeds the predetermined torque limit.
