  • Muffler-to-cab isolation mounting assembly and method for reducing cab interior noise
    Patent number: 5570861
    Abstract: A muffler mounting assembly (20) for mounting an elongated muffler apparatus (21) to a vehicle (22) for vibratory isolation thereof. The mounting assembly (20) includes a mounting bracket (23) formed for mounting to the vehicle (22), and a muffler support bracket (25) supportively contacting a periphery of the muffler apparatus (21). A pair of isolation mounting devices (27, 28) couple the support bracket (25) to an end portion of the mounting bracket (23). Each mounting device (27, 28) is positioned at a location between the support bracket (25) and the mounting bracket (23), and at substantially opposite sides of the muffler longitudinal axis (26). Further, each mounting device (27, 28) is substantially aligned in a plane (30) extending through the center of gravity (CG) of the muffler apparatus (21).
