DUAL MASTER CYLINDER ASSEMBLY

摘要

A dual master cylinder assembly for separately operating two hydraulic brake systems for a wheeled vehicle, employs two oppositely moving pistons in coaxial bores. An actuator extending transversely between the pistons carries toggle mechanism comprising a pair of links, one connected to each of the pistons, respectively. A roller at the pivotal connection between each link and its respective piston rolls on the bore surface to eliminate side loading and insure that only axial forces are applied to the pistons. As the toggle links straighten out the axial force on the pistons is multiplied.
