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.

International Classification:

B62D 61/12

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.

International Classification:

B60T 5/00
F16D 65/78

Abstract:

A vehicle, a vehicle brake cooling system, a computer program product, and a method of controlling a vehicle in a manner to achieve enhanced aerodynamic performance of the vehicle and active cooling to the wheel brakes during operation of the vehicle. The vehicle includes one or more a vehicle air vents moveable between a first position and a second position, and one or more processors of a computing system. The one or more processors are configured to dynamically conduct, in response to a detection as sensor data one or more of a current position of the vehicle air vents, a current temperature of vehicle wheel brakes, and a current speed of the vehicle, a vehicle brake analysis of the sensor data. The one or more processors are also configured to dynamically control, in response to the vehicle brake analysis and wireless network data, the vehicle air vents between the first position to enhance the aerodynamic performance of the vehicle and the second position to selectively direct ambient airflow to the vehicle wheel brakes in a manner that selectively cools the vehicle wheel brakes.

International Classification:

B60K 1/02
B60W 20/17
B60W 30/20
B60G 17/015

Abstract:

A powertrain for a vehicle may include a vehicle chassis, a rotatable vehicle drive axle, at least one selectively movable electric propulsion motor having a rotatable motor shaft rotatable about an axis defined by the rotatable vehicle drive axle, a motor actuator connected to the at least one selectively movable electric propulsion motor, and a control system in communication with the motor actuator. The control system may include a memory device in communication with the control system having instructions that when executed by the control system causes the control system to receive at least one input from at least one sensor and instruct the motor actuator to rotate the at least one selectively movable electric propulsion motor based on the at least one input from the sensor.
