Abstract: An AGSS for an RC two-wheel model composed of a wheel body, a wheel frame received in the wheel body, a spindle inserted through the wheel frame, a transmission gear assembly mounted to the spindle, a flywheel assembly mounted to the spindle, and a unidirectional rotary assembly. The unidirectional rotary assembly includes a sleeve rotatably sleeved onto the spindle, and a unidirectional rotary member mounted to the sleeve. The sleeve has external annular teeth engaging the transmission gear assembly. The unidirectional rotary member is mounted in the flywheel assembly for driving unidirectional rotation of the flywheel assembly as the RC two-wheel model gets started and for disengaging from the flywheel assembly as the RC two-wheel model brakes, such that the flywheel idles to protect the internal parts of the RC two-wheel model from inertial collision.

Abstract: An RC two-wheel model is composed of a frame assembly, a front wheel assembly, and a rear wheel assembly. The frame assembly includes a frame body and a transmission set mounted to the frame body. The front wheel assembly includes a front wheel frame and a front wheel. The front wheel frame is rotatably mounted to the frame body at a top end thereof and has a pair of front forks. The front wheel is rotatably connected with a bottom end of the two front forks. The rear wheel assembly includes a rear wheel frame connected with the frame body, and a rear wheel rotatably connected with the rear wheel frame and the transmission set. Therefore, the above design can simplify and expedite the performance calibration, assembly, and repair of the RC two-wheel model.
