Abstract
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.
Claims20
A hub motor arrangement, comprising:
- a housing comprising an interior space;
- a first lateral support member at least partially positioned within the interior space of the housing;
- a second lateral support member at least partially positioned within the interior space of the housing and spaced away from the first lateral support member;
- a plurality of connecting shafts extending between the first lateral support member and the second lateral support member;
- a plurality of planet gears, wherein each one of the plurality of planet gears is supported on a respective one of the plurality of connecting shafts;
- a motor assembly configured to drive the plurality of planet gears;
- and
- a ring gear configured to be driven by the plurality of planet gears, wherein the ring gear is configured to drive the housing to rotate about an axis of rotation in a first direction;
- and
- a one-way bearing that is configured to allow the housing to rotate freely in a second direction about the axis of rotation.
A personal mobility vehicle comprising:
- a body having a support member and being configured to support a user;
- a front wheel supported by the body;
- a rear wheel supported by the body and rotatable around an axis;
- and
- a rear drive assembly comprising a motor assembly, a plurality of gears, and a one-way bearing, wherein the rear drive assembly is supported by the body and configured to transfer rotational force to the rear wheel;
- wherein the rear drive assembly is configured to transfer rotational force in a first direction to the rear wheel and is configured to allow the rear wheel to rotate freely in a second direction.
A hub motor arrangement, comprising:
- a housing comprising an interior space;
- a plurality of connecting shafts;
- a plurality of planet gears, wherein each one of the plurality of planet gears is supported on a respective one of the plurality of connecting shafts;
- a motor assembly that is configured to drive the plurality of planet gears, wherein a first end of the motor assembly is outside the interior space of the housing on a first side of the hub motor arrangement and a second end of the motor assembly is inside the interior space of the housing;
- a ring gear that is configured to be driven by the plurality of planet gears, wherein the ring gear is configured to drive the housing to rotate about an axis of rotation;
- and
- a fixed axle, wherein a first end of the fixed axle is outside the interior space of the housing on a second side of the hub motor arrangement that is opposite the first side and a second end of the fixed axle is inside the interior space of the housing.
