Definitions
- This invention relates to a new or improved snowmobile track belt suspension.
- Snowmobile track belt suspensions often employ a slide frame pressed into contact with the upper side of the ground engaging run of the track belt loop by spring arrangements associated with suspension arm assemblies by which the slide frame is connected to the snowmobile chassis.
- suspension arm assemblies by which the slide frame is connected to the snowmobile chassis.
- two angulated arm assemblies are employed to connect the slide frame to the snowmobile chassis, and these arm assemblies are movable independently of one another to permit the slide frame to accommodate itself to static and dynamic forces arising in operation.
- Irregularities in the terrain travelled by the snowmobile produce displacements and deflections of the snowmobile front suspension that supports the vehicle on the skis, and of the rear suspension. Depending upon their magnitude, frequency, and strength, these deflections cause more or less discomfort to the operator of the snowmobile.
- the present inventor theorizes that suspension displacements that produce angular acceleration of the snowmobile and its operator about a transverse horizontal axis produce more discomfort than displacements that merely produce vertical acceleration of the vehicle and its operator.
- the invention provides a snowmobile suspension comprising: a slide frame carried on downwardly and rearwardly angled front and rear suspension arm assemblies that are supported in the snowmobile chassis, said suspension incorporating spring means acting on said arm assemblies to urge said slide frame downwardly into contact with the ground-engaging run of the snowmobile track belt; said front and rear arm assemblies being substantially equal in length and generally parallelly arranged to position said slide frame substantially horizontally with respect to the snowmobile chassis; said frame arm assembly having upper and lower ends connected to fixed first and second pivots on the snowmobile chassis and on the slide frame respectively; said rear arm assembly having an upper end connected to a third fixed pivot on said snowmobile chassis, and having a lower end connected to a displaceable pivot that is movable longitudinally of said slide frame; movement of said displaceable pivot forwardly of said slide frame being limited by an abutment that is positioned so that the suspension arms form a parallelogram linkage, and which thus prevents the front end of the slide frame from moving to a higher position than the rear end thereof relative to said chassis; guide means on said
- FIGS. 1A and 1B are generally schematic side elevations of a snowmobile
- FIG. 2 is a somewhat schematic side elevation of a slide frame and the suspension arm assemblies of a snowmobile track suspension
- FIGS. 3A and 3B are schematic views illustrating the action of the components of FIG. 2;
- FIG. 4 is a somewhat more detailed side elevational view of a snowmobile slide frame and suspension arm assemblies
- FIG. 5 is a somewhat schematic view of the front portion of the suspension of FIG. 4;
- FIG. 6 is a top rear and side perspective view of the snowmobile slide suspension of FIG. 4 .
- FIGS. 1A and 1B a snowmobile chassis 10 is schematically illustrated as being supported in the usual manner upon a pair of steerable skis 11 at its forward end and upon the ground engaging run of a driven track belt 12 at its rearward end.
- FIG. 1A represents the situation that exists with a track suspension of prior art construction wherein the loading point 13 where ground induced forces absorbed by the track suspension are applied to the snowmobile chassis is positioned rearwardly of the snowmobiles center of gravity 14 by a distance l.
- angular acceleration ⁇ applied to the snowmobile when the track encounters an undulation that generates a force F at the loading point 13 will be directly proportional to the couple T and inversely proportional to the moment of inertia I of the snowmobile about its center of gravity.
- the couple T is the product of the force F and the distance l, so that accordingly the angular acceleration for a given force F is directly proportional to the distance l.
- FIG. 1B represents the dynamic condition in which the snowmobile track suspension is re-configured so that under the same operating conditions the force F is applied at a loading point 15 that is spaced further forwardly than in FIG. 1A at a distance l′ from the center of gravity 14 . It will be appreciated that with this configuration the angular acceleration applied to the snowmobile is greatly reduced.
- the snowmobile track suspension now to be described in relation to FIGS. 2 through 6 has been designed to achieve a reduction in this angular acceleration
- the track suspension includes an elongate slide frame 21 with an upwardly curved forward end 22 , and carrying at its rear end in known manner, adjustable idler wheels 23 over which the track belt is constrained to pass.
- the slide frame 21 contacts the upper side of the ground engaging run of the track belt 12 and is in turn connected to the snowmobile chassis 10 by front and rear suspension arm assemblies 24 , 25 .
- the suspension arm assemblies 24 , 25 are of substantially the same length, and are arranged at a similar orientation, i.e. inclined downwardly from front to rear, being connected at their upper ends to fixed pivots 26 , 27 respectively on the snowmobile chassis 10 .
- the suspension arm assemblies 24 , 25 extend at substantially the same angle ⁇ to the horizontal as indicated in FIG.
- the front arm assembly having its lower end attached to a fixed pivot 28 and the rear arm assembly having its lower end attached to a movable pivot 29 .
- the movable pivot 29 is received in a guide means 30 , being movable longitudinally thereof, and the guide means defining an abutment 31 at its forward end positioned as shown in FIG. 2 .
- FIG. 2 shows the static position of the track suspension.
- the front and rear arm assemblies 24 , 25 are of the same length L and are arranged at the same angle ⁇ with respect to the horizontal, the movable pivot 29 being in this condition at the forward end of its range of movement and adjacent the abutment 31 .
- the slide frame 21 will remain horizontal as it deflects upwardly. Specifically the front end of the slide frame cannot move to a higher location than the rear end during this displacement since the movable pivot 29 is blocked by the abutment 31 .
- slide frame will be free to assume a position as shown in broken lines in FIG. 3B as might occur as a result of tension in the track 12 or otherwise. This movement is accommodated by rearward displacement of the movable pivot 29 in the guide 30 .
- the slide frame 21 comprises two transversely spaced elongate runners 35 interconnected by suitable transverse struts 36 .
- the runners 35 are upwardly curved towards their forward ends and also include on their undersides friction reducing coatings or the like (not shown) for engagement with the snowmobile track belt 12 .
- the friction generated in this engagement can be further reduced by idler wheels 37 , 38 arranged in pairs at intermediate locations on the slide frame and having lower peripheries projecting slightly below the underside of the slide frame runners 35 .
- the rear suspension arm assembly 25 as best seen in FIG. 6 comprises a horizontal upper tube 39 interconnected to a horizontal lower tube 40 by laterally spaced upwardly divergent longitudinal members 41 .
- the outboard ends of the upper tube 39 carry idler wheels 42 to support the return run (not shown) of the track belt 12 , and also support stub shafts 43 which provide the pivot attachment 27 to the snowmobile chassis.
- the lower tube 40 carries on its outboard ends the movable pivots 29 in the form of slide blocks 29 a of suitable lower friction material, which are longitudinally movable in the guide means 30 .
- each runner 35 has an upwardly extending lug plate 44 having an elongate slot through which the associated end of the lower tube 40 passes.
- the guide means 30 is defined by a cover plate 45 that is releasably secured to the lug plate 44 by suitable fastener means.
- An intermediate cross piece 46 is mounted on the longitudinal members 41 and supports the forward ends of a pair of spaced parallel gusset plates 47 the rear ends of which are supported on the lower tube 40 . Intermediate their ends the gusset plates 47 provide a pivotal mounting 48 for a bell crank plate 50 which has an intermediate pivotal connection 51 to a diagonally arranged strut 52 that is pivotally supported on the slide frame, and a further pivotal connection 53 to the lower end of a combined coiled spring/hydraulic damper unit 54 .
- the upper end of the damper unit forms a pivotal connection 55 to a radially projecting lug arm 56 that is rigidly attached to the upper tube 39 .
- damper unit 54 extends below and generally longitudinally of the rear suspension arm assembly 25 .
- the configuration of the linkage provided by the bell crank 50 , the strut 52 and the lug arm 56 is such that the resistance of the damper unit to upwards deflection of the rear suspension arm assembly 25 is applied at a desired rate.
- the front suspension arm assembly 24 is similarly configured to the rear suspension arm assembly including upper and lower tubes 39 a and 40 a interconnected by longitudinal members 41 a, the upper tube having stub shafts 43 a at its ends, but not supporting any idler wheels.
- the lower tube 41 is connected to the pivot axis 28 provided in upwardly projecting lug plates 44 a on the runners 35 .
- Gusset plates 47 a are supported between a cross piece 46 a and the lower tube 40 a and provide a pivot 48 a for a bell crank plate 50 a which is likewise pivoted at 51 a to a strut 52 a and at 53 a to the lower end of a damper unit 54 a.
- the upper end of the damper unit has a pivotal connection 55 a to a lug arm 56 a on the upper tube 39 a.
- FIGS. 4 and 6 For convenience in illustration, the elements are shown in somewhat simplified form in FIGS. 4 and 6, and in particular the damper units 54 , 54 a are shown without their coil springs. These components are of well known design and need not be illustrated in detail.
