HUB MOTOR ARRANGEMENT OR VEHICLE WITH HUB MOTOR ARRANGEMENT |
摘要 |
A ride-on vehicle, such as for a child, includes a vehicle body and one or more wheels that support the vehicle body relative to a surface. At least one of the wheels includes a hub motor arrangement that provides a drive torque for propelling the vehicle. The hub motor arrangement includes a housing defining an interior space. An axle or other mounting element(s) define an axis of rotation of the housing. Preferably, the axle or other mounting element(s) do not pass completely through the housing. A motor drives the housing through a transmission. Preferably, the motor is a standard, compact motor that is positioned on the axis of rotation and can be laterally offset from a central plane of the housing. In some embodiments, a traction element is carried directly by the housing. |

1. A hub motor arrangement, comprising:
a housing defining an interior space and an axis of rotation; a first lateral support member positioned at least partially within the interior space of the housing; a second lateral support member positioned at least partially within the interior space of the housing and spaced from the first lateral support member along the axis of rotation; a plurality of connecting shafts extending between the first lateral support member and the second lateral support member; a plurality of planet gears, each planet gear being a double spur gear supported on a respective one of the plurality of connecting shafts; a motor; a sun gear driven by the motor and that drives a first gear portion of each of the plurality of planet gears; a ring gear driven by a second gear portion of each of the plurality of planet gears, wherein the ring gear drives the housing for rotation about the axis of rotation. |
