Gearing
There are 3 different types of gearing which can be changed by replacing the timing belt from the planetary gear to the wheel axel.The gearing can be 1:1, 1:1.5 or 1:2 (or in absolute values: 28:28, 19:28 and 14:28). The planetary gearbox has a gearing of 1:12.
The combination of timing belt length and teeth on the gears is:
Right side:
Gearing 19:28 timing belt length: 250 mm.
Gearing 28:28 timing belt length: 270 mm.
Gearing 14:28 timing belt length: 240 mm.
Left side:
Gearing 19:28 timing belt length: 260 mm.
Gearing 28:28 timing belt length: 280 mm.
Gearing 14:28 timing belt length: 245 mm.
Torque needed at front wheels to turn them
Maximum is on grass and needs a torque of 2 Nm
The measurements are as follows:
Black floor in the entrance:0.4kg*0,137 m * 10 N/kg=0,55Nm
On black rubber mat in the entrance:0.6kg*0,137 m * 10 N/kg=0.822Nm
On grate outdoors:1.0kg*0,137 m * 10 N/kg=1.37Nm
On cobblestone outdoors:1.0kg*0,137 m * 10 N/kg=1.37 Nm
On grass outdoors:1.4kg*0,137 m * 10 N/kg=1,918 Nm
On dirt outdoors: 0,7 kg*0,137 m * 10 N/kg=1 Nm
Alle målinger er lavet med en vandring på minimum 90 grader hvoraf den højeste værdi er brugt.
