Publication number: 20040173390Abstract: A suspension system for suspending an endless track beneath a tracked vehicle chassis. At least one suspension arm is pivotal connection to the vehicle chassis at an upper end and pivotally connected to a suspension rail at a lower end. A biasing mechanism provides a biasing force that biases the suspension rail away from the vehicle chassis. At least one rear wheel is coupled proximate a rear portion of the suspension rail. A track tensioning system displaces the rear wheel relative to the suspension rail to apply a tensioning force to the endless track in response to displacement of the suspension arm.Type: ApplicationFiled: March 15, 2004Publication date: September 9, 2004Applicant: Formula Fast RacingInventor: Gerard J.

Publication number: 20040134702Abstract: A snowmobile assembly including a snowmobile chassis having a motor compartment at a front portion and an endless belt channel at a rear portion. A motor is located substantially in the motor compartment substantially in front of the endless belt channel. The motor includes at least one fuel control mechanism arranged toward a front portion of the snowmobile chassis. By arranging the at least one fuel control mechanism toward the front portion of the snowmobile chassis, the snowmobile assembly provides for greater mass centralization and/or a lower center of gravity than it would otherwise have if the at least one fuel control mechanism arranged toward the rear t portion of the snowmobile chassis. The greater mass centralization and/or a lower center of gravity can also be achieved by arranging the at least one exhaust port toward the rear of the snowmobile chassis. A drive train couples the motor to an endless belt drive shaft located in the endless belt channel.Type: ApplicationFiled: January 5, 2004Publication date: July 15, 2004Applicant: Formula Fast RacingInventor: Gerard J.

Patent number: 6715575Abstract: A suspension system for suspending an endless track beneath a tracked vehicle chassis. The suspension system can be a fully coupled suspension, a partially coupled suspension or a non-coupled suspension. The suspension system includes at least one elongated suspension rail having a front portion, a rear portion and a bottom track-engaging portion. At least one suspension arm has an upper end adapted for pivotal connection to the vehicle chassis and a lower end pivotally connected to the suspension rail. The lower end of the suspension arm can optionally have a displacement with a non-linear component. A biasing mechanism provides a biasing force to bias the suspension rail away from the vehicle chassis. The track tensioning system coupled to the suspension arm applies a tensioning force to the endless track in response to displacement of the suspension arm. The tensioning force generates a supplemental force transmitted by the endless track that augments the biasing force of the biasing mechanism.Type: GrantFiled: August 7, 2002Date of Patent: April 6, 2004Assignee: Formula Fast RacingInventor: Gerard J.

Patent number: 6561302Abstract: A snowmobile design, including a modular front suspension system and a stabilizer assembly, a lightweight frame structure and a drive train that reduces the center of gravity of the snowmobile. The modular front suspension system for a snowmobile that is substantially self-contained and self-supporting. The present modular front suspension system is assembled around a primary support structure, such as an extrusion or other structural member. The primary support structure can be easily attached to or detached from, the snowmobile frame. The modularity of the present suspension system decreases assembly costs. A stabilizer assembly extends through the center opening and is mechanically coupled to the ski spindle housings. The chassis for a snowmobile includes a plurality of front structural members defining a motor compartment.Type: GrantFiled: July 24, 2002Date of Patent: May 13, 2003Assignee: Formula Fast RacingInventor: Gerard J.
