  • Publication number: 20230160453
    Abstract: A magnetorheological damper, wherein the damper comprises a housing that is at least partially filed with a magnetorheological fluid, and a magnetorheological valve disposed within the housing. The valve includes a magnetically permeable core having at least one coil reservoir formed therein, and at least one conductor coil, wherein each conductor coil is disposed around a portion of the core within a respective one of the coil reservoir(s). The valve additionally includes a fluid flow path adjacent the conductor coil(s). The fluid flow path is structured and operable to allow the magnetorheological fluid to flow adjacent the conductor coil(s). The valve further includes at least one coil cover, wherein each coil cover is disposed over a respective one of the coil(s) such that the respective coil is protected from exposure to magnetorheological fluid flowing through the fluid flow path.

  • Patent number: 11092215
    Abstract: A transmission comprising an input shaft connectable to a power generation device such that the input shaft is rotatable at a power input rotational speed, an output shaft connectable to a driveline of the vehicle, and a plurality of gear sets selectable to operably connect the input shaft to the output shaft providing a rotational speed reduction ratio therebetween. The gear sets comprise a master active gear set having a master gear ratio, a slave active gear set having a slave gear ratio, and a passive gear set having a passive gear ratio. The passive gear set is operable to selectively engage the master and slave active gear sets to provide the high numeric compound ratio rotational speed reduction that is the product of the master active gear ratio, the slave active gear ratio and the passive gear ratio.
