  • Patent number: 11970231
    Abstract: A vehicle can include a first wheel, a second wheel, and a steering system. Either both the first wheel and the second wheel can be front wheels or both the first wheel and the second wheel can be rear wheels. The steering system can be configured to concurrently cause: (1) a steering angle of the first wheel to be at a first angle and (2) a steering angle of the second wheel to be at a second angle. A difference angle can be a difference of the first angle subtracted from the second angle and can be greater than an angle determined to comply with Ackermann steering geometry. Such a difference angle can act to securely brake the vehicle when the vehicle is parked at a location at which a three-dimensional shape of a topological relief of the location can complicate an effort to securely brake the vehicle.

  • Patent number: 11958448
    Abstract: A lifting system for generating a lifting force on a portion of a vehicle includes a vehicle wheel and a force-generating mechanism structured to be received inside a rim cavity of the wheel. The force-generating mechanism is also structured to be operably connected to a frame of a vehicle. A bearing member is operably connected to the force-generating mechanism. The bearing member is structured to transmit a force generated by the force-generating mechanism to a surface in physical contact with the bearing member. The bearing member is also structured for operably connecting the wheel to the force-generating mechanism. Force applied by the force-generating mechanism may be sufficient to lift a portion of the vehicle off of a ground surface, or the force may only be sufficient to apply a parking brake force without lifting the vehicle.

  • Patent number: 11530009
    Abstract: A vehicle can have: (1) a first pair of rear wheels with a first pair of tires configured to be able to bear a weight of the vehicle and (2) a second pair of rear wheels with a second pair of tires installed on the second pair of rear wheels and configured to be selectively inflatable. The first pair of wheels can be disposed on a first pair of axles. The second pair of wheels can be disposed on the first pair of axles or on a second axle. In an inflated state, the second pair of tires can be configured to be able to bear the weight of the vehicle. In a deflated state, the second pair of tires can lack being configured to bear the weight of the vehicle. An individual or a controller can cause the vehicle to have a conventional configuration or a dually configuration.

  • Publication number: 20220371558
    Abstract: Apparatuses, systems, and methods apply, with a fan, a braking force to a vehicle that includes an axle. The fan is rotated at a first rotational speed based on a rotation of the axle that rotates at a second rotational speed. The first rotational speed is different from the second rotational speed. The fan applies the braking force when the fan rotates at the first rotational speed.
