A sealed drive system for driving a drive wheel of a miniature vehicle includes a drive gear, a transfer gear and a driven gear mounted in an inside pocket, an outside pocket and a second inside pocket respectively formed in a first side plate. The transfer pocket is sealed via a gear cover closing the outside pocket, the first inside pocket is sealed to a housing in which a shaft mounting a drive gear is rotatably mounted and the second inside pocket is sealed to one side of the driven wheel. The driven wheel and driven gear are fixed together and are rotatably mounted on a shaft fixed at its axial ends to the first and a second side plate. The axial end of the driven wheel remote from the driven gear is sealed via a suitable seal. Similarly the opposite sides of the housing are are sealed one to each of the said plates and a rotatable seal is formed between the first side plate and the adjacent face of the first side plate so that a seal chamber is formed from the housing to the first inside pocket, to the transfer pocket to the second inside pocket and to the axial end of the wheel adjacent to the first side plate and between the axial and of the drive wheel remote from the driven gear to the second side plate so that all the gears and bearings may be lubricated from a common source of lubricant and the system is completely sealed.
