Abstract

The present disclosure relates to a caster wheel assembly (1) for a wheelchair, comprising: a caster housing (3), a central body (9) having a radially outwards extending flange (9a), which central body (9) is configured to be received by the caster housing (3), a spindle shaft (23) configured to be rotationally locked relative to the central body (9), a first bearing (11) having an inner bearing race (11b) configured to be rotationally locked relative to the spindle shaft (23), a friction member (13; 11a) configured to be rotationally locked relative to the caster housing (3), and a resilient member (15) configured to be arranged between the flange (9a) and the friction member (13), and configured to provide a force between the flange (9a) and the friction member (13) to thereby create friction torque between the caster housing (3) and the spindle shaft (23).
