An idler wheel assembly, for example a rear idler wheel assembly, for a snowmobile and includes at least one cross-member that permits load transfer and possible load damping as between a pair of rear idler wheels. The cross-member may be configured to transfer lateral loads, bending loads and other types of loads between the idler wheels. The cross-member is arranged between the wheels in such a manner that it is free to rotate with the idler wheels without interference to or from other structure of a skid frame assembly of the snowmobile. In one embodiment, each idler wheel includes a cross-member that extends inward to connect to the other wheel.

PIVOTABLE WHEEL ASSEMBLY FOR SNOWMOBILE SKI

Номер: US20170066503A1
Автор: Beaudoin Denis
Принадлежит:

The present invention provides a retractable wheel system for snowmobile skis. The retractable wheel system of the present invention may be installed on a snowmobile ski without affecting its structural integrity by installing the system on the reinforced portion of the snowmobile ski. When a user circulates in a path with little or no snow, the retractable wheel system is positioned in the extended configuration by the user and the system will automatically return to the retracted configuration when the user returns in a snowy zone. This is realized by using a pre-tensioned spring that will reposition the wheel in the retracted configuration. The spring transmits a rotational movement to the member on which the wheel is fixed. 1) A pivotable wheel assembly for a snowmobile ski , the pivoting wheel assembly comprising:a) a pivoting member;b) a wheel rotatably mounted to the pivoting member;c) a shaft for pivotably mounting the pivoting member to the snowmobile ski; the pivoting member comprising a first opening for rotatably mounting the wheel and a second opening for receiving the shaft;', 'wherein the wheel assembly in extended configuration has the lower portion of the wheel at a horizontal level lower than the undersurface of the snowmobile ski and the wheel is then in contact with the ground to support the weight of the snowmobile;', 'wherein in a retracted configuration the wheel is free from contact with the ground; and', 'wherein the kingpin limits the rotation of the pivoting member in the extended configuration., 'd) a kingpin securing the snowmobile to the snowmobile ski;'}2) A pivotable wheel assembly as claimed in claim 1 , further comprising a stopper operatively connected to the pivoting member for limiting the rotation of the pivoting member when in the retracted configuration.3) A pivotable wheel assembly as claimed in claim 2 , wherein the pivoting member has a width at least twice the size of its thickness.4) A pivotable wheel assembly as claimed ...

The invention is related to the class of small-scale tracked transportation vehicles, which can be used for towing a person and cargo using a sledge, for example. The motorized towing vehicle comprises a frame supporting a caterpillar drive, a platform supporting an engine with a transmission, a luggage space, an assembly for connecting to the object being towed object, a control device, and an object being towed. The caterpillar drive includes a caterpillar track, a metal subframe, a driven shaft and a driving shaft with pinions, and torsion-type wheel bogie. The control device consists of a steering wheel with handles and controls. The object being towed comprises a driver's workplace. The frame consists of a platform and a rigid framework enclosing the platform along the entire perimeter, including the luggage compartment with an additional luggage space above. The design of the frame and platform is asymmetrical relative to the track because of an extension of the platform in one direction. The subframe is in the form of metal side plates connected to the frame with brackets bent into an S-shape. The subframe plates accommodate a track tightening mechanism in the form of an eccentric and self-aligning bearings. An all-weather hood is used for protecting the engine and luggage space. The road performance of the motor towing vehicle has been improved.

Snow bike having a center of mass substantially aligned with the center of mass of a rider for enhanced stability

Номер: US20190118904A1
Автор: Barnabas LeBlanc
Принадлежит: Individual

A snow bike includes a lightweight engine and transmission to power an endless drive belt (track) around a suspension under the rear of the frame. A unique aspect of the snow bike is that the front/rear weight distribution places less load on the ski and more load on the track, thereby providing lighter steering forces and increased track traction. The snow bike is steered by a fork mounted to a tubular/sheet frame that pivots around an axis and is connected to a ski. The drivetrain directly links the transmission to the track drive wheel, thereby powering the endless track. The centerline of the transmission drive shaft falls to the aft of the drive wheel of the track. This, combined with how the forward track suspension is attached, allows the mass of the track assembly to be more centralized, positioning the center of gravity of the bike nearer to the rider.

The present invention introduces an electrically driven snowmobile, i.e. an electric sled. The electric motor is applied along the primary driving axis so that its rotational force is applied directly or indirectly to the primary driving axis. The electric motor may locate either inside or outside the frame structure of the snowmobile, and either on the left-hand side or the right-hand side of the primary driving axis. One option of manufacturing the electrically driven snowmobile is to convert a traditional combustion engine driven snowmobile into an electrical one by removing some parts and adding the electric motor within the snowmobile. Another option of manufacturing the electrically driven snowmobile is to build a transmission chain from scratch, and by adding an electric motor along the primary driving axis. 2.

SNOWMOBILE SKI DAMPENER

Номер: US20190161141A1
Автор: Aberle Ryan D.
Принадлежит:

An improved snowmobile ski dampener for dampening articulation between a steering spindle and a snowmobile ski. The ski dampener may be constructed of an elastomeric material and include one or more progressive surfaces that progressively come in contact with a base surface of the steering spindle as progressively increased compressive loads are applied between the steering spindle and snowmobile ski. As the progressive surfaces come in contact with the base surface, the shape factor of the ski dampener may change (e.g., increase), reducing compressive strain for a given compressive stress. Various design and material characteristics including width, shape of the progressive surface, and durometer and bulk modulus of the elastomeric material may be selected to provide various performance characteristics such as dampening effect, impact absorption, approach angle, initial flex force, and service life. 120-. (canceled)21. An elastomeric dampener for dampening articulation between a steering spindle and a ski of a snowmobile , comprising:a bottom side, the bottom side in contact with a top surface of the ski when installed on the ski;a top side comprising at least one surface in contact with a forward base surface of the steering spindle when the steering spindle and the ski are in a preload condition; anda plate between a first portion of the elastomeric dampener comprising the top side and a second portion of the elastomeric dampener comprising the bottom side. The present application claims the benefit of U.S. Provisional Patent Application No. 62/591,767, entitled “SNOWMOBILE URETHANE SKI DAMPENER AND POSITIONER,” filed on Nov. 29, 2017, which is hereby incorporated by reference herein.The present application relates to a snowmobile ski dampener for dampening articulation between a snowmobile ski and a steering spindle of a snowmobile.Snowmobile ski dampeners are used to provide support and articulation control between a steering spindle and a snowmobile ski. ...
