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.
Claims20
A braking system comprising:
- a fan that applies a braking force to a vehicle when the fan rotates;
- and
- a gearset that is coupled with the fan and an axle of the vehicle to rotate the fan at a first rotational speed based on a rotation of the axle that rotates at a second rotational speed, wherein the first rotational speed is different from the second rotational speed, wherein the fan applies the braking force when the fan rotates at the first rotational speed.
At least one computer readable storage medium comprising a set of instructions, which when executed by a computing device, cause the computing device to:
- determine whether a predetermined condition is met to apply a braking force to a vehicle with a fan, wherein the vehicle includes an axle;
- and
- when the predetermined condition is met, control the fan to rotate at a first rotational speed based on a rotation of the axle that rotates at a second rotational speed, wherein the first rotational speed is different from the second rotational speed, wherein the fan applies the braking force when the fan rotates at the first rotational speed.
A method to operate a braking system comprising:
- applying, with a fan, a braking force to a vehicle that includes an axle;
- and
- rotating the fan at a first rotational speed based on a rotation of the axle that rotates at a second rotational speed, wherein the first rotational speed is different from the second rotational speed, wherein the fan applies the braking force when the fan rotates at the first rotational speed.
