Drive mechanism of gearbox in remote-controlled car
12427859 · 2025-09-30 · ·

A drive mechanism of a gearbox in a remote-controlled car includes a transfer assembly and drive-switching components; the transfer assembly includes a first shaft and a second shaft arranged in parallel. A first transmission gear and a second transmission gear are rotatably sheathed outside the first shaft; the drive-switching components includes a clamping member and a driving assembly; the driving assembly drives the clamped member to move back and forth so as to be clamped with the first transmission gear, or the first transmission gear and the second transmission gear; when the clamping member is merely clamped with the first transmission gear, the first shaft rotates independently for a two-drive output; when the clamping member is clamped with the first transmission gear and the second transmission gear, the first shaft and the second shaft rotate simultaneously for a four-wheel drive output.
