  • Patent number: 11898635
    Abstract: A tensioner includes a movable section, a fixed section, a flat spiral spring, and a back-up spring. The movable section receives load from an entrained transmission body through a tension member. The fixed section supports the movable section so as to be capable of displacing. The flat spiral spring biases the movable section so as to resist the tension member. The flat spiral spring unwinds in a state in which there is a small inter-plate friction force in cases in which there is a large biasing force applied to the tension member to counter load acting from the tension member. The flat spiral spring winds-up in a state in which there is a large inter-plate friction force in cases in which there is a small biasing force applied to the tension member to counter load acting from the tension member. The back-up spring limits wind-up of the flat spiral spring.

  • Patent number: 10196057
    Abstract: A vehicle stability control device includes a yaw moment generation device and a control device. A variation yaw moment generated by simultaneous turn and acceleration/deceleration is expressed as a function of a longitudinal acceleration and a lateral acceleration. A longitudinal force and a lateral force of a tire have non-linear load dependency. The variation yaw moment when assuming that the load dependency is linear is a first variation yaw moment. The variation yaw moment considering the non-linear load dependency is a second variation yaw moment that is expressed as a product of the first variation yaw moment and a correction gain. In vehicle stability control, the control device controls the yaw moment generation device to generate a counter yaw moment counteracting the second variation yaw moment, based on the longitudinal acceleration, the lateral acceleration, and the correction gain.
