quadricycle chassis 3ds - Quadricycle Chassis by Purple Puppy

This is a very detailed model of a quadricycle. The quadricycle is a hybrid, using both pedal power and electric power. An epicyclic power split delivers the power from both the pedals and the motor to a differential gear, which then drives the two rear wheels via two telescopic driveshafts.
Without smoothing, there are 421,751 polygons and 293,648 vertices.

Many details are modeled, including (and especially) the accurate involute straight and bevel gears, the chain, the suspension setup, the steering system, and the wire wheels.
