Abstract
A rear suspension system in a two-wheeled vehicle having a body frame, a front wheel and a rear wheel. The rear suspension system comprises a rear fork member having a front end pivotably connected to the body frame and a rear end which rotatably supports the rear wheel, and an elastic band member stretched between the rear fork member and the body frame. With such arrangement, favorable comfort characteristics are ensured while at the same time weight is reduced.
Claims18
In a two-wheeled vehicle having a body frame and a rear wheel, a rear suspension system comprising:
- a rear fork member;
- said rear fork member having a front portion thereof pivotably connected to said body frame and a rear portion thereof rotatably supporting said rear wheel;
- a ring-like elastic band member stretched between said rear fork member and said body frame;
- and
- said band member comprising a plurality of spring bands at least one of which has a relatively different spring constant, said spring bands being disposed substantially in parallel with each other.
In a two-wheeled vehicle having a body frame and a rear wheel, a rear suspension system comprising:
- a rear fork member;
- said rear fork member having a front portion thereof pivotably connected to said body frame and a rear portion thereof rotatably supporting said rear wheel;
- a ring-like elastic band member stretched between said rear fork member and said body frame;
- said band member being stretched between a first shaft connected proximal said rear fork member and a second shaft connected proximal said body frame in substantially parallel relation with said first shaft;
- said rear fork member having a pair of first brackets which are disposed in spaced and opposed relation to each other in substantially the transverse direction of said vehicle, and said first shaft extends between said first brackets;
- said rear fork member being pivotably connected to said body frame through a pivot shaft;
- said pivot shaft having a pair of second brackets which are disposed in spaced and opposed relation to each other substantially the transverse direction of said vehicle;
- said second shaft extending between said second brackets;
- said second brackets comprising a pair of plate members;
- and
- said plate members being fixed at base ends thereof to said pivot shaft and at tip ends thereof to said body frame through a pair of third brackets.
In a two-wheeled vehicle having a body frame and a rear wheel, a rear suspension system comprising:
- a rear fork member;
- said rear fork member having a front portion thereof pivotably connected to said body frame and a rear portion thereof rotatably supporting said rear wheel;
- a ring-like elastic band member stretched between said rear fork member and said body frame;
- said band member being stretched between a first shaft connected proximal said rear fork member and a second shaft connected proximal said body frame in substantially parallel relation with said first shaft;
- said rear fork member having a pair of first brackets which are disposed in spaced and opposed relation to each other in substantially the transverse direction of said vehicle, and said first shaft extends between said first brackets;
- said rear fork member being pivotably connected to said body frame through a pivot shaft;
- said pivot shaft having a pair of second brackets which are disposed in spaced and opposed relation to each other substantially the transverse direction of said vehicle;
- said second shaft extending between said second brackets;
- and
- at least one of said first shaft and said second shaft being adjustable in position.
In a two-wheeled vehicle having a body frame and a rear wheel, a rear suspension system comprising:
- a rear fork member;
- said rear fork member having a front portion thereof pivotably connected to said body frame and a rear portion thereof rotatably supporting said rear wheel;
- a ring-like elastic band member stretched between said rear fork member and said body frame;
- said band member being stretched between a first shaft connected proximal said rear fork member and a second shaft connected proximal said body frame in substantially parallel relation with said first shaft;
- said first shaft and said second shaft being each provided over the outer periphery thereof with a collar portion;
- and
- a guide member shaped to substantially fit the inner surface of said elastic band being disposed between said collar member and said elastic band.
