Abstract:
1. A five-member linkage snowmobile suspension system comprising: an elongate slide rail; a first torque arm pivotably connected at a first end to a second end of the elongate slide rail at a first vertex; a snowmobile tunnel pivotably connected at a first end to a second end of the first torque arm at a second vertex; a second torque arm pivotably connected at a first end to a second end of the snowmobile tunnel at a third vertex; a scissors member pivotably connected at a first end to a second end of the second torque arm at a fourth vertex, the scissors member pivotably connected at a second end to a first end of the elongate slide rail at a fifth vertex; a first shock member configured to provide spring support to the first second vertex from the slide rail; a second shock member configured to provide spring support to the third vertex from the slide rail; and, a Remotely Adjustable Shock Member (RASM) having a first end and a second end slideably coupled to each other so as to permit contraction and expansion of a separation distance between the two ends, the first end of the RASM connected to the elongate slide rail and the second end of the RASM connected to the scissors member, the RASM having a remotely selected coupled mode and a remotely selected uncoupled mode, wherein when the coupled mode is remotely selected, the RASM presents a high resistance to change in the separation distance, which substantially fixes the position of the scissors member relative to the elongate slide rail so that the scissors member and the elongate slide rail substantially behave as a single member thereby effectively reducing the five-member linkage snowmobile suspension system to a four-member linkage snowmobile suspension system, wherein when the uncoupled mode is remotely selected, the RASM presents a low resistance to change in the separation distance, which permits substantially free pivotable movement of the scissors member relative to the elongate slide rail.
