A one piece commercial highway vehicle wheel cast from a light weight metal in mold having a core insert which forms a circumferential lightener recess in the outboard end of the wheel.

Light weight cast wheel and apparatus for casting same

An electronic controller for actuating electric wheel brakes on a towed vehicle which includes a device for sensing the electric current flowing to the towed vehicle wheel brakes. The device is operative to interrupt the flow of electric current if the current flow becomes excessive. The controller also retains gain settings if the supply of power to the controller is interrupted and has a visual display for indicating results of self-diagnostic testing.

Electronic trailer brake controller

An electrical short circuit protection device for an electric trailer brake controller includes a fuse connected between the controller and the trailer brakes and an acoustic piezoelectric transducer connected across the fuse. Upon a short circuit fault developing in the trailer brakes, the fuse opens and the transducer generates an audio warning signal.

Short circuit safety audible monitor

An electronic brake controller for actuating electric wheel brakes of a towed vehicle which includes a sleep mode.

Electronic trailer brake controller with sleep mode

An electronic brake controller for actuating electric wheel brakes of a towed vehicle which includes a zero adjusting circuit for a pendulum in an inertia sensor.

Remote manual switch

An electronic brake controller for actuating electric wheel brakes of a towed vehicle in response to actuation of the brakes of an associated towing vehicle. The brake controller includes a sensor for producing a brake control signal which is representative of the desired braking of the towed vehicle. The controller also includes a microprocessor for responsive to the brake control signal for generating an output signal for actuating the electric wheel brakes of the towed vehicle.

An electronic brake controller for actuating electric wheel brakes of a towed vehicle in response to braking of an associated towing vehicle. The controller includes a microprocessor responsive to the braking of the towing vehicle for generating an output signal for actuating the towed vehicle brakes in accordance with a brake response curve. The brake response curve can include a non-linear portion.
