ABSTRACT:
A shock absorbing suspension for the large rear wheels of a wheelchair is disclosed. A fork element is hinged at one end to a clamping member which attaches to a horizontal frame member of the wheelchair. A cylindrical solid polymer shock absorber cushions the movement of the fork element toward the clamping member. The free end of the fork element includes an axleway for the axle of a large wheelchair wheel. The movement of the fork element relative to the clamping member is limited by abutting surfaces on the fork element and the clamping member.
