Actuator Assembly And Transmission Comprising An Actuator Assembly

A transmission system comprising:

• a gearbox comprising:
• a first rail and a second rail disposed longitudinally within the gearbox, each of the first rail and second rail configured to move between a plurality of positions longitudinally, the first rail defining a first rail axis, and the second rail defining a second rail axis;
• a first shift fork located along the first rail and a second shift fork located along the second rail, each of the first shift fork and second shift fork is configured to engage and disengage at least one gear;
• an actuator assembly to move each of the first shift fork and second shift fork between the plurality of positions longitudinally, the actuator assembly removably coupled with the gearbox, the actuator assembly comprising:
• a support;
• at least one shift actuator connected to the support, the shift actuator including a rail selector, the shift actuator being configured to move the rail selector between a plurality of positions along a shift axis defined by the shift actuator;
• and
• a select actuator connected to the support and transverse to the at least one shift actuator, the select actuator received by the rail selector and moves between a first position and a second position along a select axis defined by the select actuator;
• wherein the select actuator moves from the first position to the second position rotating the rail selector about the axis defined by the shift actuator from a first radial position contacting the first rail to a second radial position contacting the second rail;
• wherein the first shift fork on the first rail is moved between a plurality of positions along the first rail axis when the rail selector is contacting the first rail and the shift actuator is actuated, and the second shift fork on the second rail is moved between a plurality of positions along the second rail axis when the rail selector is contacting the second rail and the shift actuator is actuated.

An actuator assembly driven by a fluid configured to move a plurality of shift forks between a plurality of positions longitudinally, the actuator assembly comprising:

• a support;
• a first shift actuator and a second shift actuator connected to the support, each of the shift actuators including a rail selector, each of the first shift actuator and the second shift actuators being configured to move each of the rail selectors between a plurality of positions along a first shift axis defined by the first shift actuator and a second shift axis defined by the second shift actuator, respectively;
• and
• a select actuator connected to the support and configured to be received by the rail selector;
• the select actuator is configured to move between a first position and a second position along a select axis defined by the select actuator;
• wherein the select actuator moves from the first position to the second position rotating the first rail selector about the first shift axis and the second rail selector about the second shift axis from a first radial position to a second radial position;
• wherein the first rail selector is configured to interface with a first rail axis in the first radial position and a second rail axis in the second radial position, and the second rail selector is configured to interface with a third rail axis in the first radial position and a fourth rail axis in the second radial position.
