Abstract: A locking differential gear carrier comprises a gear carrier housing, a first output shaft, a second output shaft differentially linked to the first output shaft, an internal gear affixed perpendicular to the first output shaft and disposed within the gear carrier housing, and a locking actuator assembly. The locking actuator assembly is disposed exterior to the gear carrier housing and includes a locking ring to which a pin is affixed, the locking ring movable by a servo motor toward and away from the gear carrier housing, the pin disposed in parallel with the first output shaft and passing through the gear carrier housing to selectively engage with a recess of the internal gear to lock the first output shaft to the gear carrier housing and cause the first output shaft and the second output shaft to rotate synchronously.

Abstract: Disclosed herein is a multi-axle component for a constant-velocity drive type driveshaft joint system, comprising: a rotation shaft comprising an end distal to a joint region, and an end proximate to the joint region; a generally cylindrical ball receiving housing located at the proximate end, comprising a cylindrical wall adapted to receive at least a partially spherically shaped shaft end; at least two holes provided in the cylindrical wall that are axially displaced from one another along a rotation axis of the multi-axle component; and a pin that extends through only one of the axially displaced holes at a time to join the shaft end with the multi-axle component.

Abstract: A gearbox for a model car, comprising: a housing; an input gear; an output gear; and at least one intermediate gear. The housing provides a support for each of the input gear, the output gear and each intermediate gear; and in which the gearbox has: a first operating configuration where the input gear, the output gear and at least one intermediate gear are supported by the supports and mesh to form a gear train from input gear to output gear through each intermediate gear supported by the supports; and a second operating configuration where the input gear and the output gear are supported on the supports but fewer intermediate gears are supported by the supports, such that the input gear, the output gear and any intermediate gears supported by the supports mesh to form a gear train from input gear to output gear through any remaining intermediate gears.
