CONSTRUCTION/METHODS

Most of the parts of this project need to be purchased and then assembled because it is more practical and cost efficient than manufacturing them with the resources available. The 3-D printing machine in the CWU lab will be used for parts related to housing or support parts.

The design of this project consists of two sub-assemblies that make up the drive train assembly. The transmission assembly uses gears to convert the rotational speed from the motor to the drive shaft. The gearbox assembly also uses gears and converts the rotational speed from the drive shaft to the driven shaft which powers the axles. The motor has the spur pinion attached, which mates with the spur gear to rotate the drive shaft parallel to the motor. The drive shaft has a u-joint at the end of it connecting to the adapter shaft and another connecting the adapter shaft to the bevel pinion going into the gear box. The gear box supports the driven shaft and gears with bearings and houses the bevel pinion and gear which mate to rotate the driven shaft powering the vehicle.
