Roller suspension apparatus are useful for example in belted vehicles. The heretofore known roller suspension apparatus impart a shear force to the spring due to the geometry and the relationship between the roller mounting arms, the walking beam, and the pivot pins to which the arms and beam are pivoted. The subject roller suspension apparatus has a pair of arms (34, 36) and a force transmitting beam (40) pivotally connected to a single pivot shaft (32). The mounting surfaces (46, 50, 51) to which a pair of springs (42) are attached are then arranged relative to the pivot shaft such that substantially only compressive forces are imparted to the springs. Thus, the full shock absorbing potential of the springs is fully utilized. |
