Definitions

  • This invention relates to suspension systems for use on bicycles, motor cycles and other modes of transport utilising wheels or ski's.
  • the first is to provide a lightweight and simple rear wheel suspension system, achieved by using a single pivot axis, this will be referred to as a "unipivot”.
  • the second is to incorporate a stepload system in order to prevent articulation upon component pedalling loads.
  • the fourth is to achieve these requirements in a compact package in a manner that is compatible with most bicycle frames.
  • the fifth is to offer an option of frame size reduction for transport, making use of the pivot which forms part of the suspension.
  • Figure 1 is a side elevation of a bicycle frame including the rear suspension components.
  • Figure 2 is a perspective view of the suspension unit (not including pivot) and frame surrounding elements.
  • Figure 3 is a side elevation of the suspended bearing arrangement.
  • Figure 4 is a front elevation of a linear roller bearing.
  • Figure 5 is a perspective view of the shock absorber and clamp.
  • Figure 6 is a centre-sectioned side elevation of the shock absorbing system and surrounding frame components.
  • Figure 7 is a perspective view of a complete frame and utilising the removable stay clamp.
  • Figure 8 is a side elevation of an alternative shock absorber position.
  • Figure 9 is centre sectioned elevation of the pivot system.
  • Figure 10 is a side elevation of the bottom bracket shell with pivot system attached.
  • FIG. 1 there is illustrated a bicycle mainframe 1 which includes a toptube 2, down tube 3, seat tube
  • a bicycle rear frame 10 comprising a pair of seat stays 9 and chain stays 8 respectively and a rear wheel 11.
  • Said rear frame 10 is pivotally attached directly behind said bottom bracket shell 5.
  • FIG 9 there is a pivot system comprising rear frame axle 13 and mainframe axle 14. Both these axles have inner bearing surfaces 15 which mate to a pivot pin 12.
  • the overall pivot width is greater than that of the bottom bracket shell 5 but not too great as to interfere with the pedalling action 33 of the bicycle when ridden.
  • Both the suspension housing 16 and stay runner 17 feature flat sides 18 to which bearing surfaces 19 are affixed.
  • the bearing surfaces may feature deformable backing 21 as shown in figure 3. This allows the bearing surface 19 to provide a controlled level of movement, this facilitates manufacture and tolerancing and guarantees proper torsional control.
  • the suspension housing 16 is holed on both sides 22, one hole being threaded, this permits entry within the housing of a stepload bolt 23.
  • the stay runner 17 has a vertical, axial stepload slot 32 running part of its length.
  • a stepload adjustment bolt 25 is located in the open end of the stay runner 17, threading axially through a tapped hole until reaching the stepload slot 32.
  • a hollow shock absorber 26 surrounds both the suspension housing 16 and stay runner 17, its top end mates against the seat tube 4 and its lower end mates against the seat stays 9 or part way down the suspension housing 16 to a mounting boss 27 as shown.
  • This mounting boss 27 can be moved up or down the suspension housing 16 to increase or decrease respectively the preload of the shock absorber
  • This preload level will determine the spring rate of the arrangement.
  • the rear frame 10 When a shock loading is received at the rear wheel 11 , the rear frame 10 is moved arcuately about its pivot 12 with the suspension housing 16 acting to deform the shock absorber 26 and sleeving the stay runner 17.
  • the shock absorber 26 attempts to retrieve the stay runner 7 from within the suspension housing 16 but is prevented from doing so by the stepload bolt 23 which is trapped within the stepload slot 32 of the stay runner 17.
  • a stepload adjustment bolt 25 can be used to decrease the length of the stepload slot and thus increase the level of stepload on the suspension system.
  • FIG. 7 A further refinement of the design can be seen in figure 7 where at the end of each seat stay 9 there are components to create a rear frame removal clamp 33 which permits attachment and detachment of the top of the seat stays 9 to/from the suspension housing 16/stay runner 17(depending on their configuration). On detachment, components of seat stay removal clamp 33 may remain attached to the top of each seat stay 9.
  • the rear frame 10 then moves arcuately about its pivot 1 and manoeuvres the top of the seat stays 9 to mate to a junction 34 on the down tube 3, where it can be affixed, thus producing a reduction in frame size when required.
  • the said pivot pin 12 about which the rear frame moves arcuately is located above or adjacent to the bottom bracket shell 5.
  • the pivot is of a special type described thus:
  • a removable pivot pin 12 which passes through the left side of a pivot eye bush 28, then through a pivot axle bush 29 and then through the right side of the pivot eye bush 30.
  • the pair of pivot eyes (28 and 30) and pivot axle 29 are attached either; to the rear frame axle 13 and above or near the bottom bracket shell 5 respectively, or attached above or near the bottom bracket shell 5 and to the rear frame axle 13 respectively.
  • the rear frame axle 13 is attached to the rear frame 10 in such a way as to achieve maximum width of the pivot components.
  • the rear frame axle 13 extends beyond the normal width of the bottom bracket shell 5 but is modified to just avoid contact with transmission components 33. This provides better tyre 35 to rear frame 10 clearance and permits the use of shorter chain stays 8, but most importantly achieves greater torsional control of the suspension system.
  • Figure 7 Shown if Figure 7 is a dirt cover 31 which is made from a deformable and curable material. This allows the frame builder to create a dirt cover 31 to exactly fit and protect the pivot system, whatever the exact frame construction configuration.

Abstract

Suspension pour roue arrière de bicyclette caractérisée par le montage pivotant d'un cadre arrière (10) derrière le manchon du pédalier (5). Sa largeur de pivotement est supérieure à celle de ce dernier, ce qui assure une commande en torsion élevée et simplifie la fabrication. Un boîtier de suspension (16) fait saillie au niveau des fourches arrière supérieures (9) et s'emboîte axialement ou quasi axialement sur la broche de fourche (17). A la fois le boîtier de suspension (16) et la broche de fourche (17) présentent des faces latérales plates auxquelles sont fixées des surfaces d'appui (19). Entre celles-ci se trouvent des groupes de roulements à aiguilles (20). L'une et/ou l'autre des surfaces d'appui (19) ont des faces arrière déformables (21). Une fente d'étagement d'effort (32) exerce un effort étagé sur l'axe d'étagement d'effort (23) et sur la suspension de sorte que seul un effort dû à un passage sur une bosse et dépassant le seuil d'étagement d'effort déclenchera la suspension. Un amortisseur creux (26) entoure à la fois le boîtier de suspension (16) et la broche de fourche (17). Lorsqu'une charge de choc est reçu au niveau de la roue arrière (11), le cadre arrière (10) se déplace de manière arquée autour de son pivot (12), le boîtier de suspension et le moyeu de montage (27) servant à déformer l'amortisseur (26) et à envelopper d'une gaine la broche de fourche (17).
