Device for detecting steering operation force

Номер: US20120004808A1

Автор: Akira Kuramori

Принадлежит: Yokohama Rubber Co Ltd

A steering operation force detection device for a steering wheel including a steering wheel rim having a right-side rim section and a left-side rim section. The device includes load cells that detect six component forces of the steering operation force acting on the right-side rim section and the left-side rim section consisting of forces in three axial directions and moments about three axes. The device includes a steering angle detection sensor that detects a steering angle of the steering wheel, and an inertial force component correcting unit that derives an inertial force component acting on the right-side rim section and the left-side rim section due to rotation of the steering wheel, based on an amount of displacement of the steering angle detected by the steering angle detection sensor, and that corrects the component force detected by the load cells to eliminate an effect of the derived inertial force component.

To well remove a noise component due to vibration of a flexible member from an original detection signal output from a detecting unit and suppress a phase delay of a detection signal obtained by filtering. For this purpose, the present invention provides a detecting unit including a flexible member deforming according to a state of an object to be measured and a sensor detecting an amount of deformation of the flexible member and outputting an original detection signal indicating a detection result. A filtering unit outputs a detection signal obtained by filtering the original detection signal using a filter coefficient. A calculating device calculates a vibration frequency of the flexible member contained in the original detection signal. A changing unit changes a filter coefficient of the filtering unit to cause the filtering unit to function as a filter for attenuating the vibration frequency calculated by the calculating device.

An assembly for measuring torque and/or axial load for capping heads comprises a containing body, a torque and/or load sensor housed within the body, and an interface that connects a capping head to the body. The interface is coupled to the torque/load sensor to transfer torque applied on the interface to the torque sensor and/or to transfer load applied on the interface to the load sensor. The interface comprises a first part fixedly constrained to the capping head such that the first part is brought into rotation and/or translation by the capping head, and a second part coupled to the torque sensor for transferring a torque thereto and/or to the load sensor for transferring a load thereto. The torque and/or load are applied by the first part to the second part, and the first part transfers a torque to the second part in the absence of a reciprocal contact. 110111213112050112012132012201320215021502212132120222021202220: An assembly for measuring torque and/or axial load () for capping heads , comprising a containing body () , at least one torque sensor () and/or at least one load sensor () housed within the containing body () , and interface means () adapted to connect a capping head () with the containing body () , such interface means () being coupled to the at least one torque sensor () and/or to the at least one load sensor () in a manner which is suitable to transfer a torque applied on the interface means () to the at least one torque sensor () and/or to transfer a load applied on the interface means () to the at least one load sensor () , wherein the interface means () comprise at least a first part () , which is fixedly constrained to the capping head () in such a way that the first part () is brought into rotation and/or translation by the capping head () , and a second part () , which is coupled to the at least one torque sensor () for transferring a torque thereto and/or to the at least one load sensor () for transferring a load thereto , which torque ...
