Dually drive wheel assembly
View Patent ↗In general, one aspect disclosed features an apparatus comprising: a mobile agricultural structure; and at least one wheel assembly mechanically coupled to the mobile agricultural structure, wherein each wheel assembly comprises: two or more wheels, a motor disposed between two of the wheels, a drive transference mechanically coupled to the motor and the wheels, wherein the motor is configured to turn the drive transference and the wheels together, a housing, wherein the motor is enclosed by the housing, and a rotatable mechanical linkage mechanically coupled between the housing and the mobile agricultural structure.
1 . An apparatus comprising:
a mobile agricultural structure comprising a floorless enclosure with multiple wall barriers and a roof barrier; and
multiple wheel assemblies mechanically coupled to the mobile agricultural structure, wherein each wheel assembly comprises:
two or more wheels with one or more lockable hubs,
a motor disposed between two of the wheels,
a drive transference mechanically coupled to the motor and the wheels via the one or more lockable hubs, wherein the motor is configured to turn the drive transference and the wheels together when all of the one or more lockable hubs are locked, and wherein when one of the one or more lockable hubs is unlocked, the motor is configured to turn the drive transference and only half of the two or more wheels,
such that where each wheel assembly comprises two wheels and one of the one or more lockable hubs is unlocked, one wheel is turned by the motor allowing the wheel assembly to change direction of the mobile agricultural structure, and
such that where each wheel assembly comprises more than two wheels, half of the more than two wheels are turned by the motor allowing the wheel assembly to change direction of the mobile agricultural structure; and
a housing, wherein the motor is enclosed by the housing and the housing is disposed between two of the wheels.
2 . The apparatus of claim 1 , wherein:
the motor is an electric motor.
3 . The apparatus of claim 2 , wherein:
the motor is a three-phase motor.
4 . The apparatus of claim 2 , wherein:
the motor is a DC motor.
5 . The apparatus of claim 1 , wherein:
the motor is a hollow-bore motor.
6 . The apparatus of claim 1 , further comprising a rotatable mechanical linkage mechanically coupled between the housing and the mobile agricultural structure, wherein:
the rotatable mechanical linkage comprises a lock, wherein when the lock is engaged, the housing does not rotate with respect to the mobile agricultural structure.
7 . The apparatus of claim 6 , wherein the lock comprises:
a plurality of slotted grooves; and
a movable pin, wherein the movable pin is moved into one of the slotted grooves to engage the lock.
8 . An a mobile agricultural structure comprising a floorless enclosure with multiple wall barriers and a roof barrier comprising:
two or more wheels with one or more lockable hubs;
a motor disposed between two of the wheels with a housing enclosing the motor;
a drive transference mechanically coupled to the motor and the wheels via the one or more lockable hubs; and
wherein the motor is configured to turn the drive transference and the wheels together when all of the one or more lockable hubs are locked, and wherein when one of the one or more lockable hubs is unlocked, the motor is configured to turn the drive transference and only some of the two or more wheels allowing the wheel assembly to change direction of the mobile agricultural structure.
9 . The apparatus of claim 8 , wherein:
the motor is an electric motor.
10 . The apparatus of claim 9 , wherein:
the motor is a three-phase motor.
11 . The apparatus of claim 9 , wherein:
the motor is a DC motor.
12 . The apparatus of claim 8 , wherein:
the motor is a hollow-bore motor.
13 . The apparatus of claim 8 , further comprising:
the housing, wherein the motor is enclosed by the housing.
14 . The apparatus of claim 13 , further comprising:
a platform; and
a rotatable mechanical linkage mechanically coupled between the housing and the platform.
15 . The apparatus of claim 14 , wherein:
the rotatable mechanical linkage comprises a lock, wherein when the lock is engaged, the housing does not rotate with respect to the platform.
16 . The apparatus of claim 15 , wherein the lock comprises:
a plurality of slotted grooves; and
a movable pin, wherein the movable pin is moved into one of the slotted grooves to engage the lock.
17 . The apparatus of claim 14 , wherein:
the platform is a mobile agricultural structure.
18 . The apparatus of claim 14 , further comprising:
the platform is a mobile fence.
