  • Patent number: 7000727
    Abstract: A go-kart drive assembly with an internal combustion engine in the form of a reciprocating-piston or rotary-piston engine as a power source is described. The drive assembly includes a spur-gear reduction gearing between the internal combustion engine and a rear-wheel drive shaft of the go-kart. The spur-gear reduction gearing and the crank shaft (17) of the reciprocating engine or the engine shaft of the rotary-piston engine (17a) are accommodated in a common housing (10) that is preferably closed. The space or spaces (a, b) between the shafts of the spur-gear reduction gearing (27, 29; 30, 33) is fixed in the housing (10) so as to be invariable. The driving gear wheel (27) of the gearing (26) is mounted on the crank shaft (17) or the engine shaft (17a) and the driven gear wheel (33) of the gearing (26) is mounted on the rear-wheel drive shaft (6).
