Description

Sell:  Great solution. 4 winters have been tested and the prototype works great. New for snowmobiles/snow vehicles.) The patent fixes the biggest durability problems in snowmobiles. Also the possibility of a license. ( In addition, possible patent infringement.) The patent is sold based on bids. The future of snowmobile suspension!
The invention offers several advantages. One significant advantage is that the free mass of the snowmobile is significantly reduced, typically up to about 20 kg compared to suspension structures implemented in the area defined by the track system. It is clear that the solution according to the invention offers cost advantages compared to known solutions, because fewer parts and thus maintenance items are needed. Smaller mass also saves fuel consumption.rnThe invention can also offer significant advantages in suspension durability. One object prone to breaking on snowmobiles is the so-called suspension failure of the front end of the hanger or track system. The reason for this is that the front suspension part is typically inclined to the direction of impact. With the invention, the suspension member can be arranged in a position where it preferably receives shocks in the natural operating position, i.e. the shock is mainly directed in the linear direction of the linearly functioning suspension member.rnThe invention also avoids the use of latches or lever arms in the implementation of the suspension.rnThe invention achieves the advantage that the actual suspension travel of the snowmobile or the travel of the rear part increases by up to 15-20 cm. This is due to the fact that the roller can be made very low, in which case the distance between the upper surface and the lower surface is significantly shorter than in structures where the suspension is arranged inside the roller.rnBecause the track system is low, it can be allowed to travel more vertically, which naturally results in better suspension.rnWith the help of the invention, the contact surface of the roller with the ground increases, because the lower structure enables the roller to be extended in the longitudinal direction of the snowmobile.rn The invention makes it easier to adjust the height of the suspension and the damping force, because the suspension elements are easy to handle above the rail. In one embodiment, the frame has multiple attachment points for the support arms, allowing flexibility to be adjusted
