Definitions

  • the present invention relates to an arrangement for the suspension of a number of wheels on a chassis with opposite sides comprising two wheel suspensions, where each wheel suspension is arranged on each side, where each wheel suspension comprises a suspension frame, two support frames and a first spring arrangement and where the suspension frame is connected to the chassis, where each support frame is provided with an arrangement of at least three connection points, where the support frame is rotably connected to the suspension frame at a first connection point, where the support frame is connected to a wheel axle at a second connection point, where the support frame is connected to the first spring arrangement at a third connection point, and where the third connection point is arranged below the first and second connection point.
  • trailers differ in dimension and use, e.g. large trailers exist for the transporting of horses, bikes, cars, garden vehicles or the like, while small trailers are used for transporting goods (e.g. when people move from one house to another).
  • the car road holding qualities are reduced when towing a trailer.
  • trailer manufacturers have tried to enhance the trailer road holding qualities.
  • One way to enhance these qualities is to provide the wheels of the trailer with a suspension arrangement, hence slight road roughness is taken up by the suspension arrangement, and the trailer travels more smoothly on the road, hence improving the car road holding qualities.
  • Tilting of the trailer bed practically renders approach ramps obsolete. Tilting of the trailer bed is carried out mechanically or manually and makes it easier for the user to load large amounts of goods, a vehicle or an animal.
  • EP-A1-0930181 shows and describes an arrangement for raising or lowering the trailer bed by means of a cylinder.
  • the stop members prevent the suspension frame/wheels from rotating freely around a connection point at the chassis. Furthermore, the two suspension frames rotate in the same direction, and by means of this arrangement it is possible to control the tilting of the trailer bed.
  • DE 1 280 685 shows a suspension arrangement for a lorry or a truck.
  • This suspension arrangement has an adjustable ground clearance.
  • the two suspension frames in each side rotate in opposite direction and the suspension frames is connected to a common spring and damper arrangement.
  • This arrangement is well suited for a suspension with relatively large wheels as the wheel centre is spaced apart, or for a suspension where a large distance between the axels of buggy is intended.
  • Another object of the present invention is to provide an arrangement, which can be mounted on trailers of different dimension.
  • Yet another object of the present invention is to provide an arrangement providing a low trailer clearance height.
  • Arranging the support frames with this shorter distance between the support frames is determined by the fact that the distance between the wheels should be as little as possible. This is due to the fact that it is difficult to turn a trailer when the distance between the wheels is too large, and furthermore it is possible to obtain a high tilt angle of the trailer bed, if the wheels/support frames are positioned relatively close to each other.
  • the support frames are arranged on the suspension frame in such a manner that the distance between the second connection points of the adjacent support frames is shorter than the distance between the first connection points of the adjacent support frames.
  • the arrangement for the suspension of a number of wheels on a chassis with opposite sides comprises two wheel suspensions, where each wheel suspension is arranged on each side on the chassis, thereby avoiding the use of a through-going wheel axle; hence making it possible to avoid the width consideration of the trailer, when mounting an arrangement according to the present invention on a trailer.
  • the arrangement makes the suspension arrangement more flexible and allows trailer manufacturers to use standard components for the suspension arrangement regardless of the trailer type.
  • the wheel suspension comprises a suspension frame, two support frames and a first spring arrangement, where the suspension frame is connected to the chassis, and the two support frames are mounted on the suspension frame and connected by means of the first spring arrangement.
  • each wheel suspension allows each wheel suspension to absorb different impacts of the two wheels connected to the support frame. Due to the wheel suspensions in both sides of the chassis of the trailer, the trailer's front and back wheel are more or less independent of each others movements, and the wheels are sideways totally independent. This causes e.g. the wheels to follow any bumps or holes in the road, meanwhile the three other wheels remain on the road surface either in the same vertical position or in different vertical positions.
  • the arrangement allows opposite rotation of the two support frames, thus causing opposite displacement of the wheels connected to the support frame hence the arrangement can be used when tilting the trailer bed.
  • the third connection point is arranged below the first and the second connection point on the support frame, and furthermore the angle between the line between the first connection point and the second connection point and the line between the third connection point and the second connection point are approximately perpendicular.
  • the angle between the line between the first connection point and the second connection point and the line between the third connection point and the second connection point influence the tilting motion of the trailer bed.
  • the angle between the line between the first connection point and the second connection point and the line between the third connection point and the second connection point can both be less than 90 degrees or larger than 90 degrees.
  • each support frame further- more, comprises a fourth connection point in which is arranged a second spring arrangement connecting the support frame with the chassis.
  • the second spring arrangement could comprise a shock absorber, whereby it is only necessary for the first spring arrangement to comprise a spring for the arrangement to work properly.
  • the third connection point could be connected along with the second spring arrangement.
  • the suspension frame is provided with a number of stop members adapted to prevent free rotation of the support frame around the first connection point.
  • the stop members are arranged in such a manner on the suspension frame that they prevent the support frame from rotating more than 30-50 degrees either way from a non-operating position of the support frame.
  • the first stop member acting on a first support frame equally prevents further rotation of the second support frame, and vice versa the second stop member acting on the second support frame equally prevents further rotation of the first support frame.
  • the stop members can therefore be arranged in pairs either below or above the support frame.
  • the stop members are provided with a contact surface, which rests against a part of the support frame, when the support frame is rotated 30-50 degrees from the non- operating position of the support frame.
  • a torsion spring or bar which is integrated in the assembly of the first connection point between the support frame and the suspension frame, could be used.
  • the suspension frame is provided with means for reinforcement.
  • the means for reinforcement could be one or more of the following: ribs, fins, gills, ledges, feathers or profiles, which are arranged longitudinally or transversally on a side of the suspension frame.
  • An alternative to reinforcing the suspension frame is to provide the suspension frame in one sheet of material with bends.
  • the bending of the material provides the rigidity of the suspension frame.
  • the suspension frame is provided in one piece with a number of bends along one edge part, hence the bends allow the suspension frame to be mounted around a girder of the chassis.
  • the suspension frame is provided with a recess at a lower edge, wherein the spring arrangement is arranged entirely or partly.
  • the recess is shaped to receive the spring arrangement, particularly when tilting the frailer bed.
  • the axis of the spring arrangement is stunted so the spring arrangement, which is arranged between the third connection points of two support frames in a non-operating position is positioned higher than a straight line connecting the third connection points of the two support frames.
  • the suspension frame is shaped as one unit, whereto it is possible to connect two support frames.
  • the suspension frame is shaped by a number of frame parts.
  • the suspension frame is shaped by two bearing frames. Each bearing frame is mounted on the subsurface of the chassis and is rotably connected to the first connection point of the support frame.
  • bearing frames allows the trailer manufacturer to:
  • each bearing frame has a surface in contact with the subsurface of the chassis.
  • Increase the distance between the support frames because the axes connecting the support frame and the bearing frame is longer, hence the torque caused by the sup- port frame is absorbed better.
  • the first and second spring arrangements comprise a linear push unit or pull unit.
  • the first spring arrange- ment is a linear push unit due to the fact that use of a linear push unit allows the manufacturer to produce a very compact arrangement and provides the best possibility of mounting the arrangement on different types of chassis'.
  • the first and second spring arrangements comprise one of the following or a combination of the following:
  • Oil shock absorber e.g. rubber pad
  • the first spring arrangement comprises a shock absorber enclosed by e.g. a coil spring.
  • a shock absorber enclosed by e.g. a coil spring.
  • the transmission of power in the spring arrangement is dependent on the velocity by which the wheels are affected.
  • the weight distribution between the front and the back wheel connected to the arrangement is always 50/50 because of the wheel's relatively vertical motion in relation to each other. Both wheels are affected by a force of similar size, however, the forces are oppositely directed, hence the wheels always maintain contact with the ground, if the rotation of the support frame is not otherwise limited.
  • the first spring arrangement is replaced by a solid connection, which is shorter than the axle of the first spring arrangement, hence the wheels are drawn up under the chassis. This feature is advantageous, when the trailer is stored or when a low loading height is required or during transport requiring a stable and compact trailer.
  • the first spring arrangement is provided with a clamp unit, which can be mounted on the spring arrangement, hence preventing the extension and retraction of the spring in the spring arrangement. The following two configurations exist: the wheels are drawn up under the chassis, when the clamp prevents extension of the spring, hence lowering the trailer bed.

  • Fig. 2 shows a plan view of the wheel suspension
  • Fig. 3 shows a side view of a support frame

  • Fig. 1 and 2 shows a wheel suspension 1 comprising a suspension frame 2, two support frames 3 and a first spring arrangement 4.
  • the suspension frame 1 is connected to the chassis (not shown).
  • the two support frames 3 are connected to the suspension frame 2.
  • the first spring arrangement 4 comprises a shock absorber 5 enclosed by a coil spring 6.
  • the wheels 7 are connected to the support frames 3.
  • Fig. 3 shows a support frame 3 which is provided with an arrangement of at least three connection points 8, 9, 10, where support frame 3 is rotably connected to the suspension frame (not shown) at a first connection point 8, where the support frame 3 is con- nected to a wheel axle (not shown) at a second connection point 9, where the support frame 3 is connected to the first spring arrangement (not shown) at a third connection point 10, and where the third connection point 10 is arranged below the first and second connection point 8, 9 on the support frame 3.
  • Fig. 1 and 2 show that the support frames 3 are arranged on the suspension frame 2 in such a manner that the distance between the second connection points 9 of the adjacent support frames 3 is shorter than the distance between the first connection points 8 of the adjacent support frames 3. Hence the arrangement is symmetrical around a cen- tral vertical axis.
  • Fig. 4 shows a wheel suspension 1 with stop members 11 mounted on the suspension frame 2 above the support frames 3.
  • the stop members 11 prevent free rotation of the support frames 3.
  • the first spring arrangement 4 is shown with a stunted axle 12, hence the first spring arrangement 4 is arranged in the recess 13 of the suspension frame 2 and thereby the height of the wheel suspension 1 is reduced.
  • Fig. 5 shows a wheel suspension 1 where the wheels 7 are positioned in different positions and the spring arrangement 4 is moved to the right side of recess 13. This con- figuration occurs either when the trailer bed (nor shown) is tilted or if the left wheel 7 is affected by a large bump on the road.
