Abstract RU 2531669 C1

FIELD: transport.

SUBSTANCE: snow mobile comprised frame with bearing surfaces, preferably, skis. Frame supports seat and controls, mechanical drive including engine with chain gearing and propulsor to convert and to transmit driver's physical force to propulsor elements interacting with bearing surface and driving said snow mobile. Said propulsor is composed of three-arm spider driven by chain gearing. Skis are arranged at vertices of said spider to spin about said spider at their attachment to arms. Dents are made at ski running surface to make skis run in one direction. Nearby said spider, extra spider is arranged with arms in number not smaller than the main spider. Arms of extra spider are connected with arms of drive spider by vertical links at equal distances from rotational axes of spiders so that in-plane parallel skis displacement in vertical plane occurs at main spider rotation.

EFFECT: decreased weight, better slip.
