Abstract
Official abstract text for this publication.
A parking brake system for a work vehicle may include an internal braking mechanism and an external brake actuator. The brake actuator may generally include a housing at least partially defining a rod-side chamber, a secondary chamber and a piston-side chamber extending between the rod-side and secondary chambers. The brake actuator may also include a primary piston movable between a first position at which the braking mechanism is actuated to an engaged state and a second position at which the braking mechanism is actuated to a disengaged state. In addition, the brake actuator may include a secondary piston at least partially housed within the secondary chamber that is configured to apply a force against the primary piston when fluid is supplied within the secondary chamber in order to move the primary piston from the first position to the second position.
First claim
Opening claim text (preview).
What is claimed is: 1. A parking brake system for use with a transmission of a work vehicle, the parking brake system comprising: a braking mechanism housed within the transmission; and a brake actuator positioned outside the transmission, the brake actuator being coupled to the braking mechanism to allow the braking mechanism to be actuated between an engaged state and a disengaged state, the brake actuator comprising: a housing extending between a first end and a second end,…
