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).

VEHICLE WITH VARIABLE CASTER ANGLE
20170274704 · 2017-09-28 · ·

A work vehicle includes a chassis; a primary wheel carried by the chassis; and a caster assembly carried by the chassis. The caster assembly includes a pivotable swivel structure defining a caster angle; and a caster wheel swivelly linked to the swivel structure and defining a wheelbase relative to the primary wheel. A change in the wheelbase passively causes the swivel structure to pivot and change the caster angle.

Cart caster capable of converting into fixed or swivel type according to travel direction
09770945 · 2017-09-26 ·

The present invention relates to a cart caster that is installed on each of the edges of a bottom surface of a manned and unmanned cart to carry a product through a rolling motion, and more particularly, to a cart caster that is automatically converted into a fixed or rotating caster according to a forward/backward traveling direction of a cart to ensure safe travel and thereby easily carry a product and improve work conditions. According to the present invention, since the cart caster is automatically converted into a fixed or rotating caster by an operation of a swiveling conversion unit including an auxiliary wheel that is closely contacted to a wheel according to the forward/backward movement of the cart so as to rotate in only one direction and a fixing pin inserted into a coupling hole of a fixing plate, safe travel may be ensured in order to easily carry a product and improve work conditions.

Caster comprising a running wheel
11247509 · 2022-02-15 · ·

A caster includes a running wheel, a fork and an assembly journal, wherein the fork is pivotable in relation to the assembly journal and a braking device is arranged in the fork and can be displaced into the braking position via a tappet actuated by a trip cam. A direction lock can be set without a braking action on the running wheel. Two tappets are movable independently of each other, wherein only the direction lock without a braking action can be set via one of the tappets. Another caster includes a running wheel, a fork and an assembly journal, wherein a braking device is provided in the fork and can be displaced into the braking position via a trip cam. The braking device has a first braking part for friction-locking action on the running wheel and a second braking part for the interlocking lock of the running wheel.
