摘要： A cam for a brake is provided that allows for greater brake shoe travel and thicker brake linings while providing the same or greater mechanical force as compared to conventional cams. One or more lobes of the cam include multiple portions having varying profiles in axial cross-section. The variation in the cam profiles results in a cam in which the outermost ends or tips of the lobes are longer than in conventional cams yet retain the same mechanical strength.

摘要： A brake actuator redirects pressurized air that compressed a parking brake spring to the other side of a piston upon release of the parking brake spring. The redirected air is clean air which removes contaminates and pushes them out a one-way check exhaust. A first embodiment of the brake actuator uses an external quick release valve to take exhaust air from a pressure chamber and direct it to the spring chamber. A second embodiment of the brake actuator uses the spring brake control valve to take exhaust air from the pressure chamber and direct it to the spring chamber. In each embodiment, the pressurized air pushes out the excess air past the one-way check exhaust, carrying all contaminates with it. The brake actuator can also advantageously be operated under water without the water entering the spring chamber.
摘要翻译：在释放驻车制动弹簧时，制动器执行器将压缩驻车制动器弹簧的加压空气重新定向到活塞的另一侧。重定向的空气是清洁的空气，其清除污染物并将它们推出单向检查排气。制动器致动器的第一实施例使用外部快速释放阀从压力室排出空气并将其引导到弹簧室。制动器执行器的第二实施例使用弹簧制动控制阀从压力室排出空气并将其引导到弹簧室。在每个实施例中，加压空气将多余的空气推过单向检查排气，携带所有污染物。制动器致动器还可以有利地在水下操作而不使水进入弹簧室。

摘要： A clutch assembly 100 is provided for a motor having an armature shaft and a worm shaft having a worm constructed and arranged to engage a gear. The clutch assembly includes a clutch housing 112 including a race surface 132; a cam 117 coupled to the worm shaft; follower structure 122 operatively associated with the cam; a clutch plate 114, and a clutch coupler 118 associated with the clutch plate, the cam, and the follower structure. The coupler is coupled to the armature shaft for rotation therewith, such that rotation of the coupler rotates the clutch plate, the cam and follower structure, and thus the worm shaft. During a back drive condition of the motor, when torque is transmitted to the worm shaft and thus to the cam, the cam is constructed and arranged to causes the follower structure 122 to contact and exert pressure on the race surface 132 thereby preventing rotation of the worm shaft.

摘要： An incremental braking apparatus and method includes a first rotating member having a plurality of rigid stops spaced circumferentially around an outer cylindrical surface of the first rotating member, and a plurality of flexible stops arranged in a plurality of rows on a stationary member. The flexible stops are selectively movable toward the first rotating member from a disengaged position into an engaged position in which the flexible stops engage the rigid stops to provide a braking action on the first rotating member. An actuator with a beveled edge for engaging the outer ends of the flexible stops is operable to move a selected number of rows of the flexible stops into their engaged positions to provide an incremental braking effect. The rows of flexible stops are staggered such that the flexible stops in adjacent rows are not in circumferential alignment.
