Methods of vehicle suspension

Abstract

A method is provided, including providing a hub for mounting a wheel to a frame; providing a first mounting pivotally connected at one end to a first position on the frame; providing a second mounting pivotally connected at one end to a second position on the frame; providing a first arm which is coupled at a first position to the top of the hub and pivotally connected at a second position to the other end of the first mounting; providing a second arm which is coupled at a first position to the bottom of the hub and pivotally connected at a second position to the other end of the second mounting; and providing a shock absorber coupled at one end to a third position on the second arm between the first and second positions on the second arm and at the other end to a third position on the frame.

1 . A method comprising:
 providing a hub for mounting a wheel to a frame;   providing a first mounting pivotally connected at one end to a first predetermined position on the frame;   providing a second mounting pivotally connected at one end to a second predetermined position on the frame;   providing a first arm which is coupled at a first predetermined position to the top of the hub and pivotally connected at a second predetermined position to the other end of the first mounting;   providing a second arm which is coupled at a first predetermined position to the bottom of the hub and pivotally connected at a second predetermined position to the other end of the second mounting; and   providing a shock absorber coupled at one end to a third predetermined position on the second arm between the first and second predetermined positions on the second arm and at the other end to a third predetermined position on the frame.   
     
     
         2 . The method according to  claim 1 , wherein
 the third predetermined position on the frame is such that the shock absorber extends and contracts essentially parallel to the motion of the hub.   
     
     
         3 . The method according to  claim 1 , wherein
 the hub, first arm and second arm are all parts of the same physical element.   
     
     
         4 . A method comprising:
 providing a hub for mounting a wheel to a frame;   providing a first mounting pivotally connected at one end to a first predetermined position on the frame;   providing a second mounting pivotally connected at one end to a second predetermined position on the frame;   providing a first arm which is coupled at a first predetermined position to the top of the hub and pivotally connected at a second predetermined position to the other end of the first mounting;   providing a second arm which is coupled at a first predetermined position to the bottom of the hub and pivotally connected at a second predetermined position to the other end of the second mounting; and   providing a shock absorber coupled at one end to a predetermined position on the second mounting and at the other end to a third predetermined position on the first arm.   
     
     
         5 . The method according to  claim 4 , wherein
 the third predetermined position on the first arm is further from the hub than the second predetermined position.   
     
     
         6 . The method according to  claim 4 , wherein
 the hub, first arm and second arm are all parts of the same physical element.
