Abstract
(EN)
An exemplary actuator includes a motor, a transmission, and a support structure. The motor includes two torque sources that apply respective input torques to a rotor, which rotates about a rotation axis in response to a net input torque. The torque sources are arranged such that the input torques are additive, resulting in a vector-summated torque output. The torque sources also generate corresponding reactive torques that are applied to the first stator and the second stator. The transmission couples and constrains the first stator and the second stator such that rotational motion of one stator causes counter rotation of the other stator. Thus, the reactive torques are subtractive resulting a differential torque output. In some applications, the differential torque output is used to actuate a suspension of a vehicle. The actuator is also coupled to the vehicle via the support structure, which also reflects a reaction force or torque to actuate other subsystems (e.g., anti-dive, anti-squat).

La présente invention concerne un actionneur donné à titre illustratif comprenant un moteur, une transmission et une structure de support. Le moteur comprend deux sources de couple qui appliquent des couples d'entrée respectifs à un rotor, qui tourne autour d'un axe de rotation en réponse à un couple d'entrée net. Les sources de couple sont agencées de sorte que les couples d'entrée sont additifs, ce qui permet d'obtenir une sortie de couple à sommation vectorielle. Les sources de couple produisent également des couples réactifs correspondants qui sont appliqués au premier stator et au second stator. La transmission accouple et contraint le premier stator et le second stator de sorte qu'un mouvement de rotation d'un stator entraîne une contre-rotation de l'autre stator. Ainsi, les couples réactifs sont soustractifs, ce qui permet d'obtenir une sortie de couple différentielle. Dans certaines applications, la sortie de couple différentielle est utilisée afin d'actionner une suspension d'un véhicule. L'actionneur est également accouplé au véhicule par l'intermédiaire de la structure de support, qui reflète également une force ou un couple de réaction afin d'actionner d'autres sous-systèmes (par exemple, anti-plongée, anti-cabrage).
