Abstract:
A system for mechanically coupled multi-variator actuation is disclosed. One system includes: a first hydraulic variator comprising: a first hydraulic pump; and a first hydraulic motor linked to the first hydraulic pump. The system may further include a second hydraulic variator comprising: a second hydraulic pump; and a second hydraulic motor linked to the second hydraulic pump. The system may further include a first actuator linked to the first hydraulic pump and configured to control a displacement of the first hydraulic pump; a second actuator linked to the second hydraulic pump and configured to control a displacement of the second hydraulic pump; and a mechanical link connecting the first actuator and the second actuator, the mechanical link configured to facilitate a coordinated operation of the first actuator and the second actuator.
