Abstract: A brake shoe (14) for an internal drum brake assembly (10) having a mass damper (60) is disclosed for attenuating objectionable noise. The mass damper (60) is attached to an arcuate table (40) of a brake shoe (14) at a predetermined location adjacent to an anti-node corresponding to a flutter mode of vibration. The mass damper (60) is disposed adjacent to an arcuate edge 56 of the arcuate table (40).

Abstract: A compartment closure tilt assist mechanism that, independently of the operation of any counterbalance means in the compartment hinges, is effective to reduce the opening or lift effort for raising the closure to provide access to the compartment therebeneath. The assist mechanism comprises a lift arm 17 supported on a support strut 13 extending longitudinally of the compartment. Interposed between the lift arm and support strut are lift arm support links that are swingable about a pivot axis located below the strut. The links extend from the pivot axis angularly upwardly above the strut and support the lift arm between the closure and the strut in closed position of the closure. Over-center biasing means 33, coupled to the support strut and to the lift arm, are operative to reduce the lift effort to raise the compartment closure.

Abstract: A gearshift mechanism for a manually controlled transmission adapted for use with a tilt cab truck wherein provision is made for mounting the gearshift mechanism to permit a free floating action thereby obtaining compliance with the motion of the cab relative to the truck frame and chassis.
