Abstract
A compact transmission for use in radio controlled model electric vehicles which includes a differential assembly and a slipper clutch assembly in combination with a drive means in the form of a spur gear, all contained in a single compact unit. The unit occupies substantially the same space as the differential assembly alone and does not add any significant weight to the transmission. The differential assembly is rotatably mounted within the spur gear. Clutch pads are disposed within the central opening of the spur gear and are in slippable contact with a clutch plate which is adjacent to and prevented from independent movement by one end cap of the differential housing. The slipper clutch assembly includes an adjustment nut easily rotated to adjust the compressive force of the clutch pads against the clutch plate and fixed in place when the desired compressive force is attained. Means interposed between the adjustment nut and the spur gear enable the adjustability of the compressive force. Any adjustment can be made without having to take the mechanism apart or to remove any parts. The clutch pads and spur gear can easily be replaced as needed. In use this transmission significantly reduces damage to the motor and drive train of the model vehicle even when undergoing the most rigorous trials.
