Definitions

  • This invention relates to a suspension system for the front fork of a two- wheeled vehicle, most commonly a bicycle, and more precisely to a suspended front fork assembly intended for installation on a standard bicycle at a position in the bicycle frame where a suspended or non-suspended fork normally is attached to the head tube
  • the fork assembly can be installed to the bicycle's head tube with interchangeable bushings and adapters, so that it can be installed no matter what the dimension or existing means of attachment to the head tube are
  • the invention includes an adjustable external member which is outside the head tube, so the fork has no tube which must be passed up through the frame's head tube, something that normally necessitates cutting off the tube for adaptation to the bicycle

  • the spring device and the damper device are not illustrated in this figure, which is also without reference numerals.
  • the lower pair of linkage members are shorter than the upper linkage member, an impact to the front-wheel, i.e. to the hub attachment point 22 at the lower end of the fork legs 21 , will cause the hub attachment point to move less backwards than the backward travel of support bearing 36. Since the lower linkage member pair is shorter than the upper linkage member, the fork legs 21 and the hub attachment point 22 will rotate forward under compression of the assembly. The fork hub attachment point 22 will then move in an arc which deviates only little from a straight line parallel to an imaginary line in extension of the bicycle head tube 50. (The distance between the two parallel lines men ⁇ tioned, is referred to as «rake».)
  • a suspension mechanism must be placed between two parts which move in relation to each other, and in the embodiment illustrated in fig. 4, an effective placement is chosen by attaching a coil spring device 41 to the upper linkage member 34 at a support point 18, and by using a support point 32 on a tab in the lower part of the fork bridge 27.

  • Spring and damper mechanisms 41 , 39 can be provided on both sides of the wheel.
  • the distance between the support points 32, 33 down on the fork bridge 27 and the support points on the upper linkage member 34 will decrease when the fork legs 21 are impacted by forces from below via the hub attachment point 22, and this will cause absorption and damping of the energy indused by a bump.
  • the fork bridge is replaced by a solid support bolt which connects the fork legs and also serves as a lower support for the upper linkage member.
  • the fork crown is primarily construc ⁇ ted of bent sheet material, with openings/holes taken out to decrease construction weight.
  • the fork crown thereby has an inner and an outer portion, and the lower linkage members are journalled at their upper end between downward pointing side portions of the inner and upper parts of the fork crown.

  • the support bolt 33 on the tab of the fork bridge 27 will be able to move a short distance in an oblong opening 57 without any friction effect acting.
  • the Iength of the free travel can be pre-determined by the use of a screw in the end of the piston rod 56, as the end of the screw 58 can be shifted upwards and effectively make the oblong opening 57 shorter when the screw head 59 is operated.
  • a friction casing 54 engages the piston rod 56 directly, and is subject to wear.

Tightening/adjustment of the friction can be effected since two of the parts, 54 and 55 are conical, as shown in the figure, and since they are surrounded by a tightening casing 53 which is threaded so that it can be screwed to cause the springy casing 55 to tighten against the friction casing 54.
  • a certain amount of automatic self-adjustment is effected by the springy casing 55 itself, so that it will not be necessary to tighten the friction amount to often thereafter
  • the sleeve part 62 can of course just as well comprise an oil damper of a type which is known per se.
