International Classification:

B60T 7/06

US Classification:

74512

Abstract:

A pedal module includes a support structure, and a lever rotatably mounted to the support structure for rotation about a rotation axis. The lever includes a lower pedal portion and an upper guide portion. A cam plate is attached to the support structure and defines a cam slot. A guide rod is coupled to the upper guide portion of the lever, and is also coupled to the cam plate to follow the cam slot. A biasing device includes a first end coupled to the support structure, and a second end coupled to the guide rod, and is operable to bias the guide rod toward the rotation axis. Resistance to movement of the lever in a first rotational direction about the rotation axis is dependent upon a spring constant of the biasing device, and a profile of the cam slot perpendicular to the rotation axis.

Abstract:

A wheel assembly for an electric vehicle includes a wheel rim that is concentrically disposed about a central axis. A propulsion-braking module is disposed within an interior region of the wheel rim. The propulsion-braking module rotatably supports the wheel rim for rotation about the central axis. The propulsion-braking module includes a liquid cooled electric motor having a rotor rotatable about the central axis, and a stator disposed radially inside the rotor relative to the central axis. A motor-wheel interface hub is fixedly attached to the wheel rim, and is directly attached to the rotor for rotation with the rotor. The motor-wheel interface hub directly transmits torque from the electric motor to the wheel rim at a 1:1 ratio. The propulsion-braking module includes a drum brake system having an electric motor that rotates a cam device, which actuates the brake shoes.
