Definitions

  • the invention refers to a snowmobile comprising a pair of glide means.
  • Snowmobiles with a pair of glide means are known. Some of these snowmobiles have a wide track width and are, thus, favorable in some situations such as when driving on hard surfaces such as a snowmobile track, but awkward in other situations.
  • US 6,467,787 shows a steering mechanism for a snowmobile_with a pair of glide means.
  • the steering mechanism enables the driver to more easily displace his or her body sideways as well as steering the vehicle from this position.
  • the different needs of the driving conditions really call for different snowmobiles, which means that today either the vehicle will be good for one purpose, but not so good for the other, or vice versa. Alternatively, it is configured as a compromise.
  • the snow ⁇ mobile is not easily tiltable. This is due to the positions of the axes around which the snow ⁇ mobile must be tilted. These axes each extend from one ski to the edge of the drive belt on each side of the snowmobile. If for instance the vehicle is making a right turn, it must be tilted by rotating it around the right hand side tilt axis. This involves elevating the snowmo ⁇ bile up. The effort (tilting moment) necessary to do this depends on the weight of the snow ⁇ mobile, the longitudinal position of the center of gravity, the width of both the drive belt and the front track between the skis as well as the resilience of the ground surface.
  • the known single track snowmobiles always have to be controlled by the driver against falling (tipping over). In some driving conditions it is - as discussed - beneficial to be able to easily tilt the vehicle. In other conditions however, such as when driving slowly and at standstill, and when driving on hard or icy tracks, the snowmobile should be stabilized against falling, and not have the freedom to tilt. If not - such as with single track snowmo ⁇ biles - there are the following drawbacks:
  • a snowmobile compris ⁇ ing a pair of glide means, characterized in that a track width of said pair of glide means is variable.
  • the track width can be adjusted according to the current situation.
  • the track width can be narrow when riding fast or when riding in deep snow.
  • Such a narrow track width particularly enhances tiltability of the snowmobile, what is advantageous.
  • the track width can be adjusted to be wide, particularly when riding at a low velocity or during standstill, stabilizing the snowmobile.
  • the track width is variable during riding.
  • the snowmobile is made to react to changing riding conditions quite flexible.
  • Said glide means are preferably front skis.
  • a glide means orientation defining rod being coupled, on the one hand, to said glide means and, on the other hand, pivotably coupled to a chassis, wherein a coupling of said glide means ori ⁇ entation defining rod to said chassis is positioned to ensure that a glide means orientation defined by said glide means orientation defining rod is essentially independent of said track width.
  • the glide means orientation defining rod is preferably a steering rod.
  • said glide means or front skis, respectively, serve for steering the snowmobile.
  • the glide means are coupled to a chassis by means of pendulum arms mounted to said chassis pivotably about axes transverse to a glide means main plane.
  • the variation of the track width is performed by moving said pendulum arms around said axes, i.e. like scissors.
  • This is a quite simple construction.
  • cardan joints or spherical joints for coupling said pendulum arms to said chassis.
  • momenta around the longitudinal axis of the pendulum arms are absorbed, what is important particularly during cornering of the snow- mobile. In the case of spherical joints, said momenta have to be absorbed by other means.
  • one of the pivot axes of a cardan joint for coupling said pendulum arm to said chassis is inclined relative to a pivoting axis of a joint for coupling an extendable track width adjusting means to said chassis.
  • said pendulum arm and said glide means orientation defining rod are parallel parts of a parallelogram or trapezoid mechanism. What is achieved by this feature is that the glide means orientation is essentially independent of the track width.
  • the glide means are biased to a wide track configuration.
  • the narrow track configuration is only realized in case that a driver performs a respective control of the snowmobile, e.g. by pressing a button or by actuating a lever. Releasing the button or lever, respectively, imme ⁇ diately results in the snowmobile being adjusted to the wide track configuration because of the bias. Thereby, a high level of security is achieved. .
  • the snowmobile has a drive means, wherein the track of at least one of said glide means at least partially overlaps with the track of said drive means, in at least one track width configuration.
  • the glide means serves for compacting the snow before the snow is engaged by the drive means, resulting in a more efficient driving of the snow ⁇ mobile.
  • said one glide means track overlaps with said drive means track by at least 25 % of the glide means track in a narrowest track width con- figuration.
  • the snowmobile com ⁇ prises a suspension assembly for connecting said glide means to a chassis, said suspen- sion assembly being adapted to allow said glide means to move transverse to their main planes, but in opposite directions, in order to tilt said chassis.
  • said suspension assembly comprises a glide means orientation defining rod being, on the one hand, coupled to a glide means and, on the other hand, pivotably coupled to said chassis, wherein a coupling of said glide means orientation defining rod to said chassis is positioned to ensure that a glide means orientation defined by said glide means orientation defining rod is essentially independent of said glide means movement transverse to the glide means main plane.
  • a tilting movement does not influence the orientation of the glide means and, thus, needs not to be compensated by respective steering movements.
  • what is provided is "zero bump steer”.
  • Said glide means orientation defining rod is preferably a steering rod.
  • the snowmobile is preferably steerable by respectively controlling the position of said glide means, which might be front skis.
  • Said suspension assembly preferably comprises a pendulum arm for coupling a glide means to said chassis. This is a very simple solution for attaching said glide means to the chassis.
  • said coupling of said glide means orientation defining rod to said chassis is positioned approximately on a rotating pivot through a joint for coupling said pendulum arm to said chassis.
  • said coupling of said glide means orientation defining rod to said chassis is positioned in a "neutral area".
  • approximately is that the position might vary with view to usual tolerances and imperfec ⁇ tions.
  • the exact optimum position depends on various circumstances and on the overall geometry of the glide means suspension.
  • a line through a joint for cou ⁇ pling said pendulum arm to said chassis and through a joint for coupling said glide means orientation defining rod to said chassis is inclined relative to a horizontal line perpendicular to a lengthwise direction of the snowmobile.
  • said line through said joint for coupling said pendulum arm to said chas- sis and through said joint for coupling said glide means orientation defining rod to said chassis goes through a joint for coupling an extendable track width adjusting means to said chassis.
  • an inclination angle as seen from above is 4 to 30 degrees and an inclination angle as seen from the front of the snowmobile is 0 to 5 degrees.
  • a force acting against said movement of said glide means is variable.
  • a force acting against tilting of the snowmobile is variable. This is particularly advantageous with view to the fact that a tilting should be more easily performed when rid- ing at high speed, whereas it should be not so easily be performed particularly during standstill. During standstill, a tilting might be completely prevented.
  • the force acting against said movement of said glide means and, thereby, against tilting is dependent on the track width.
  • easy tilting should be possible in a narrow track configuration, whereas a tilting should not be so easy in a wide track configuration.
  • an angular position of a means applying said force rela ⁇ tive to said suspension is dependent on the track width.
  • a height of a front part of the snowmobile is dependent on the track width.
  • said glide means are coupled to a suspension assembly by joint means, said joint means allowing said glide means to pivot around axes parallel to the main plane of said glide means, but not around an axis transverse to said main plane.
  • said glide means is biased around an axis parallel to its lengthwise direction into a position parallel to a main plane of the snow ⁇ mobile.
  • said glide means is always urged to return in a position parallel to the main plane of the snowmobile and, thereby, into a position parallel to a horizontal plane when standing on horizontal ground, to further stabilize the snowmobile.
  • a very simple solution according to the invention includes that a biasing force results from torsion.
  • the invention provides preferably for a front ski suspension with a track which is varied according to the conditions during riding.
  • the track may be extremely narrow when it is in the narrow configuration. This greatly enhances tilting at will by the driver.
  • the skis - when in a very narrow track - will compact the snow before it is engaged by a driving belt.
  • the track may be very wide when it is in the wide track configuration. This enhances stability against falling (tipping over).
  • the several purposes of the invention are thus to allow a new type of snowmobile to be driven according to the needs of the conditions. This will make the operation of the snowmobile easier as well as reduce the strain on the driver - as well as on a potential pas ⁇ senger. This would improve the safety of the operation of the snowmobile. Furthermore, it is the purpose of some embodiments of the invention to increase the traction of the drive belt in deep-snow conditions. This will improve the operation and increase the usefulness of the snowmobile. Another purpose of some embodiments of the invention is to enable a snow ⁇ mobile in a cost-efficient manner. This is done by providing a simple and effective mecha ⁇ nism to achieve the purpose.
  • the above purposes are preferably achieved by providing a suspension mechanism which varies the track of two front skis.
  • the mechanism is suspended on springs and dampers which are effective in the narrow and wide track configurations as well as in all intermediate positions in between.
  • the ratio between tilting angle and vertical (referring to the snowmobile) movement of the skis, thus suspension springs, thus resistance against tilting, preferably varies with the track. This means that when the skis are in the narrow track positions, tilting is achieved by one ski going up and the other one going down (referring to the snowmobile).
  • the skis are preferably steerable in all track configurations, and the steered direction is not noticea ⁇ bly influenced by the track width itself. This means that a change of track during speed does not influence the direction into which the snowmobile is steered.
  • Cost effectiveness of the invention is preferably achieved by providing a mechanism which may readily be adapted to current snowmobiles.
  • the mechanism itself preferably consists of a minimum of parts, and standard mechanical elements such as bearings, joints and tubes are used to a large extent.
  • Cost effectiveness of the invention may preferably also be achieved by utilizing a pressurized oil lubrication system to be found on some snowmobile engines to actuate the variation of the track.

  • Suspension spring and damper units 13 control the vertical (seen in the direction of the snowmobile) movements of pendulum arms 1 by being attached to said pendulum arms 1 as well as to the chassis (not shown) of the snowmobile by spherical joints.

It is understood that when in this position, any vertical movements of the skis 5, thus of pendulum arms 1 , are not influencing the steered straight ahead direction of skis 5.
  • the mechanism has "zero bump steer". This applies to all track configurations of the mechanism.
  • Said extendable elements 9 control the track. When they are governed to be short, the mechanism has a narrow track. When they are governed to be long, the track is wide.
  • said extendable elements 9 may be actuators controlled by electricity or cylinder and piston assemblies controlled by fluid or compressed air. It is fur ⁇ thermore understood that said elements may contain springs which act against the ele- ments being compressed, in other words tend to keep them extended.
  • Pendulum arms 1 and steering rods 6, together with steering arms 4 and the dis ⁇ tance between joints 7 (or 11) and 16 configures or nearly configures a parallelogram mechanism.
  • a trapezoid mechanism can be used. It can be shown that the mechanism can be deployed with a practical geometry which provides parallel skis 5 in both the narrow and wide track configurations, as well as parallelism or near parallelism in the positions in between.
  • the preferred use of the mechanism is to either drive the snowmobile with a wide or narrow track, the positions in between being transitional, effected in as little as one second or a little more. It is therefore understood that a slight out of parallelism in this phase will have but a minor, temporary and hardly noticeable influence on the steered direction.
  • a typical drive belt width today is 380 mm, and skis 5 typically have a width of 180 mm. With these skis, it is possible to have a narrow track of 200 mm between the center planes of the skis. It is now realized that this lines up well with drive belt A both for tilting as well as for the skis compressing deep and loose snow before it is engaged by drive belt A.
  • Figure 4 shows how the vertical ski movements induced by tilting vary according to the width of the track between skis 5. This clearly shows the usefulness of varying the track according to the need of the situation:
  • the snowmobile When in a narrow track configuration, the snowmobile may be tilted against the sus ⁇ pension springs, with one ski being forced up and the other down.
  • the vertical movements needed for this are small, so that tilting is facilitated.
  • here "vertical movements” are understood to be in the vertical direction of the snowmobile when standing on horizontal ground.
  • the vertical movements is this track position are denounced a1 and a2 in figure 4, and it is clear that they are so small that they are well within the normal vertical suspension movements of the mechanism.
  • 19 denounces a ground plane which the vertical movements refer to.
  • the natural or regular track configuration of the snowmobile is the wide track.
  • the snowmobile is parked in the wide track configuration, and ridden in the wide track condition, similar to conventional snowmobiles, until the driver decides that he or she wants to drive in the narrow track condition.
  • the respective change over may then be achieved by the driver actuating and holding a button or lever on the steering handlebar.
  • the transition from the wide track to the narrow track takes a second or so.
  • the snowmobile now stays with the narrow track for as long as the button or lever, respectively, is held, and will immediately go back to the wide track condition, when the button or lever, respectively, is released.
  • This mode of operation is a parallel to the frequently used method of controlling accelerators of snowmobiles, thus will intuitively fit well together with this.
  • both the accelerator and the track controlling button or lever will then be released.
  • the engine speed will get down, the drive transmission will be disengaged and the track will go to the wide position, enabling the snowmobile to come to rest in an upright position.
  • Figure 5 shows a useful enhancement of the ski attachment.
  • reference nu- meral 20 refers to a wedged-shaped yoke which is fixed to a torsion spring 24, which latter is pivotally attached to the ski body by two bearing blocks 22.
  • Torsion spring 24 is rotatably fixed to ski 5 by means of an anchor block 23. The effect of this is that the orientation of ski 5 may to some extent be allowed to adapt to the situation, such as when driving on a surface which is not very resilient, never- theless tilting is still called for.
  • This may come in combination with using a drive belt A which is adapted for more easily allowing tilting such as for example through having more resilient edges.
  • the angular freedom of the attachment may be limited by - for example - limiting surfaces 21 which stop further rotation when they hit ski 5. These stops may be cushioned by layers of rubber.
  • the figure shows one preferred embodiment. However, it is clear that there are many alternative solutions such as placing the torsion spring by a pin and having rubber springs attached to the wedge block and so on.
  • Figure 6 shows yet another useful improvement of the suspension: It is beneficial to have soft suspension springs when the skis are in the narrow track to facilitate the tilting movements of the skis. Conversely, it is beneficial to have somewhat suffer suspension springs in the wide track position to secure the vehicle against tilting/leaning out of the curve.
  • said ratio is higher.
  • the effects of this are soft suspension springs in the narrow track position, and harder suspension springs in the wide track position.
  • the angular position of spring and damper units 13 relative to the suspension assembly and, thus, relative to skis 5 is dependent on the track width.
  • the needs of the different driving conditions may however in some cases be oppo ⁇ site: A large clearance to the ground may be wanted in deep-snow conditions where the narrow track is most likely to be used, whereas a low center of gravity is wanted in the wide track positions where stability against leaning out of curves are wanted.
  • the right hand side half-figures of figure 6 show how this can be solved by lengthening and shortening the sus ⁇ pension spring and damper units according to the needs. This may for example be done through hydraulic means, as indicated by flexible tubes 25.
  • said extendable elements 9 shown in Figures 2 and 3 are of a hydraulic type, said suspension units may conveniently be coupled to the same control system.
  • Figure 7 shows a ski suspension and steering mechanism with the pendulum arms pivoting around axes 26 which are at an angle ⁇ (13.5°) to a horizontal line perpendicular to the lengthwise direction of the skis (or of the snowmobile). It is understood that - seen in a front view of the snowmobile - a similar deviation of the axes compared to a horizontal di ⁇ rection may also be applied. Now it is understood that the ski movements in the vertical direction of the snowmobile change the angle of the main plane of the skis - as seen in a front view of the snowmobile - due to the pivoting action around axis 26. It can be shown that this effect may to some extent be useful, particularly in the wide track position of the skis.
