  • Inertia actuated servomotor for a trailer
    Patent number: 3990749
    Abstract: A tow vehicle-trailer braking system having independently operated tow vehicle and trailer brakes. The tow vehicle brakes are actuated by a master cylinder. The master cylinder is responsive to an input force supplied by an operator. When the tow vehicle brakes are actuated, a deceleration force will be created in the tow vehicle. The trailer brakes are operated by a servomotor. The servomotor has a pivotally positioned lever arm on which an adjustable weight is located. The weight is moved in response to the deceleration force created by the tow vehicle. The weight pivots the lever around a pin and supplies a control valve in the servomotor with an input force to independently operate the wheel brakes in the trailer.
