Abstract: The invention is a differential and braking assembly for use in two wheel drive vehicles. The apparatus accepts rotary power through rotary input means and transfers it through a differential to two separate outputs, allowing the driving wheels to rotate at different speeds while the vehicle is cornering. A one-way clutch is employed to allow the two outputs to freewheel or coast in the forward direction, at the same or different speeds, without rotation of the rotary input means. Reversal of the rotary input means actuates a brake which slows or stops the differential case. This in turn slows or stops both outputs while still maintaining the differential action for vehicle cornering during deceleration. In addition, the apparatus includes an antiback travel feature which automatically engages the brake when the vehicle travels backward and a parking brake feature by which the brake remains set at the braking level employed. The brake may always be released by the application of forward rotary input power or by actuation of a brake release pawl which allows the normally non-rotational brake mechanism to rotate with the differential input. This also allows the vehicle to be driven in reverse by application of input power with a ''''direction'''' opposite to the normal input.

Abstract translation: 本发明是用于两轮驱动车辆的差速和制动组件。 该设备通过旋转输入装置接受旋转动力，并将其通过差速器传递到两个独立的输出，允许驱动轮在车辆转弯时以不同的速度旋转。 单向离合器用于允许两个输出以相同或不同的速度在向前方向上飞行或滑行，而不旋转旋转输入装置。 旋转输入装置的反转致动一个减速或停止差动箱的制动器。 这反过来减速或停止两个输出，同时在减速期间仍然保持车辆转弯的差速动作。 另外，该装置还包括一个反向行进功能，当车辆向后行进时，自动接合制动器，以及一个驻车制动器特征，通过该停车制动功能，制动器保持设置在所采用的制动水平。 通过施加正向旋转输入动力或通过致动制动释放爪来允许制动器总是被释放，制动释放爪允许正常非旋转制动机构与差速器输入一起旋转。 这也允许通过使用与正常输入相反的“方向”的输入功率来反向驱动车辆。
