发明名称 FRAME BEAMING REDUCTION ASSEMBLY
摘要 A frame beaming reduction assembly for use with a motor vehicle to eliminate or reduce the amplitude of frame beaming oscillations in a vehicle's frame caused by vibratory forces exerted on a motor vehicle. The assembly includes a frame having a beaming frequency in a first range of frequencies, and an engine is attached to the frame wherein the engine generates engine vibration that has a second range of frequencies that is different than the first range of frequencies. A spring is positioned between a cross member of the frame and a forward engine mount of the engine. A damper formed by a pair of shock absorbers is positioned between the frame and a second forward engine mount substantially parallel to the spring such that the combination of the damper, the spring, and the engine has an offsetting frequency that is substantially equal to the frame's beaming frequency and that offsets the beaming frequency. The frame beaming reduction assembly effectively reduces the amplitude of the beaming frequency to approximately zero, whereby the frame beaming frequency oscillations are canceled and do not negatively impact the ride of the vehicle.
