An integrated electromagnet comprises a magnetic yoke and magnetic poles in two rows. An axis of magnetic core in the magnetic pole is perpendicular to the magnetic yoke. The magnetic poles comprise first and second magnetic poles that are arranged alternatively in a row. The first magnetic pole in any row is adjacent to the second magnetic pole in the other row. The first magnetic poles in a row are connected to a one-way output controller and the second magnetic poles in a row are connected to a bidirectional output controller. In a guiding state, the magnetic poles in a row have a same polarity, and a polarity of the magnetic poles in one row is opposite to that in the other row; current output by the bidirectional output controller in a braking state has direction opposite to current output by the bidirectional output controller in the guiding state.

A parking brake apparatus is provided for a vehicle including a vehicle drive train that extends between a vehicle propulsion engine and a vehicle wheel. The parking brake apparatus comprises a wheel drum located away from the vehicle wheel and fixedly attached to a drivetrain shaft that extends along a portion of the vehicle drive train between the vehicle propulsion engine and the vehicle wheel. The parking brake apparatus also comprises activatable drum brake components disposed in an interior chamber of the wheel drum. When activated, the drum brake components apply a clamping force to the wheel drum to prevent the wheel drum and the drivetrain shaft fixedly attached thereto from rotating and thereby preventing the vehicle wheel from rotating to provide the vehicle with a parking brake functionality.

A magnetic brake assembly for use with a wheel rim is described. The brake assembly includes a rotor secured to rotate with the rim and a stator secured to be rotationally stationary relative to the rotor. One of the rotor and stator has an electrically conductive body and the other of the rotor and stator has a magnetic array including a plurality of magnets configured to generate a magnetic flux. An actuator is connected to at least one of the electrically conductive body and magnetic array to selectively effect a brake mode and a non-brake mode. In the brake mode, the magnetic array induces eddy currents in the electrically conductive body to generate a magnetic braking force when the rim rotates above a threshold speed and in the non-brake mode, the induced eddy currents cause a negligible or no magnetic braking force as the rim rotates above the threshold speed.
