Definitions

  • This invention relates to a wheel suspension device for vehicles, preferably light lorries and small buses.
  • This invention relates to at new type of air spring suspension which is very simple regarding the construction and therefore becomes non-expensive, relatively spoken, to manufacture. Another important advantage with this new invention is that it can simply be applied on existing vehicles which are already on the roads, and on which the rear wheels are suspended by means of leaf springs.
  • This known wheel suspension system is common today for instance in small buses and light goods vehicles.
  • Fig 1 shows a perspective view obliquely from behind of a first embodiment of the new wheel suspension device, which is intended for the rear wheels of a vehicle
  • Fig 2 shows a close-up view of the right part of the wheel suspension device according to fig 1
  • Fig 3 shows a close-up view of the left part of the wheel suspension device according to fig 1
  • Fig 4 shows a view from the front and obliquely from above of a second embodiment of the new wheel suspension device
  • Fig 5 shows a view from behind of the wheel suspension device according to fig 4.
  • Each wheel suspension means 1, 2 comprises an underlying plate 3, on the top side of which the lower part of an air bellows 4 is fastened.
  • the upper part of the air bellows 4 is fastened on the underside of another plate 5.
  • This plate 5 is provided with two parallel flanges 6, 7, which project upwards and are intended to extend in the longi ⁇ tudinal direction of the vehicle. The distance between the flanges 6, 7 is adapted to the
  • the plate 5 provided with the flanges is kept in place on the frame member by two bolts 8, 9 which penetrate the two flanges and the frame member.
  • the first plate 3 is provided with an upwards projecting flange 10 at its rear part at an area which when applying the wheel suspension means is intended to be outside the air bellows 4.
  • a horisontal, oblong hole 11 which is intended for the rear part of a leaf spring 12 or the like.
  • leaf spring 12 is suitably fastened to the flange 10 by means of a bolt 13. Due to that fact is made possible a safe fastening of the leaf spring in the wheel suspension means.
  • the fore part of the plate 3 at the area outside the bellows 4 is provided with an upwards projecting flange 14.
  • a plate 15 which projects forwards and which is essentially horisontal in the mounting position.
  • a projecting portion 18, 19 On each side of the flange 14 between its vertical edge portion 16 and the side edge portion 17 of the plate 15 there is a projecting portion 18, 19.
  • the purpose of these portions is that they shall function as contact supports for a wheel axle 20 of the rear wheels of the vehicle.
  • the flange 14 in the same way as the flange 10 is provided with a horisontal, oblong hole 21 at the area just below the plate 15, through which the leaf spring 12 is intended to be inserted.
  • the portions 18, 19 function in this position as side supports for the leaf spring 12.
  • the leaf spring 12 and the wheel axle 20 are kept fastened on the wheel suspension means 1, 2 by a screw joint.
  • the screw joint comprises two U-formed screw means 22, 23 which surrounds the wheel axle 20 and goes through the plate 15.
  • the fore part of the plate 3 at the area inside the bellows 4 is provided with a further portion 24, which projects upwards. This portion cooperates with a further U-formed screw means 25 for holding a portion of the rear axle positioned inside that portion of the rear axle which is surrounded by the screw means 22, 23.
  • the screw means 22, 23, 25 and the cooperation with the plate 15 result in that the leaf spring 12 as well as the wheel axle 20 become extremely safely fastened to the two wheel suspension means.
  • the rear part of the plate 3 of the right wheel suspension means 1 at the area inside the bellows 4 is provided with a portion 26, which projects upwards, and the rear part of the plate 5 of the left wheel suspension means 2 at the area inside the bellows 4 is provided with a portion 27, which projects downwards.
  • a bar 28 is articulately fastened.
  • the bar 28 connects the wheel suspension means 1 , 2 with each other and functions as a stabilizer.
  • the plate 3 with the upwards projecting portions 10, 24 is provided with lightening holes (see for instance the hole 29) in order that the weight shall be kept at a low level.
  • the purpose of the holes of the horisontal part of the plate 3 is to lead away dirty water.
  • a valve means 30 is arranged on the top side of the plate 5. By this valve means, air can be evacuated from and be pumped into the air bellows 4.
  • an important advantage with this invention is that it makes possible a mounting of air spring suspension not only in new vehicles but also in used vehicles, the rear wheels of which are suspended by means of leaf springs. Such a mounting shall be described hereinafter.
  • the work starts with the fact that the rear part of the existing leaf spring 12 is cut away, whereby the fore part of the leaf spring with its suspension means 31 remains, which means 31 is articulately arranged.
  • the wheel means 1 is applied on the leaf spring 12 in that way that the rear part of the leaf spring 12 is brought through the hole 11 of the flange 10 and the hole 21 of the flange 14.
  • the wheel suspension means 1, 2 is hanging on the leaf spring 12, side support being received from the portions 18, 19.
  • the wheel suspension means is brought forwards so far that the portions 18, 19 of the plate 3 comes into contact with the rear axle 20 of the vehicle.
  • the leaf spring 12 and the rear axle 20 are fastened by means of the plate 15 and the screw means 22, 23.
  • the leaf spring 12 is fastened to the upwards projecting flange 10 at the hole 11 by means of the bolt 13, and the rear axle 20 is further secured to the plate 3 by the screw means 25. Thereafter the plate 5 with the flanges 6, 7 are fastened to the frame member of the vehicle by screws. Finally, the bar 28 is applied to the two wheel suspension means for connecting of these ones together.
  • the screw means 22, 23 and 25 preferably comprise the original clamps of the vehicle.
  • FIG. 4 In figs 4 and 5 is shown a second embodiment of the invention, intended to be used on anou er type of lorry /bus and the one for which the first embodiment is intended.
  • This second embodiment is principally built up in the same way as the one previously described. Accordingly, it comprises two separate wheel suspension means 32, 33, each one of which having an air bellows 34, 35, and which are connected to each other by a stabilizing bar 36. In using position and outside each one of the air bellows 34, 35 there is arranged a means 37, 38, through which the leaf spring of the vehicle is intended to be inserted and then fastened to the means by the bolts 39.
  • each air bellows 34, 35 is provided with further means 42, 43 by which the device according to the invention can be fastened to the longitudinal frame members of the vechicle.
  • transverse girder 44 which connects the two wheel suspension means 32, 33 with each other, and which is fastened to two plates 45, 46 which constitute the upper supporting surface of respective air bellows.
  • plates 45, 46 can with advantage also function like those means 42, 43 by which the device according to the invention is fastened to the frame members of the vehicle.
  • the lower supporting surface (plate) of the one air bellows 34 is indicated with the numeral 47.
