[WIP] Ute supercar
Zerobricks posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
I decided to start a new supercar project and after lots of thinkign decided to make an ute just because nobody else made one yet AFAIK. For those who don't know what an ute is, it's when a pickup and a normal or sports car really like each other and end up having a child like this: For this project I set myself the following goals: Unibody construction - The model will have no chassis per-se, the body will be load carrying, something @nicjasno is really good at. Convertible - If you have a sports pickup, why not make it a convertible? This will also force me to make the unibody extremely solid, since there wont be any roof support. Motorized with gearbox - I am using a new high efficiency gearbox idea. Power will be delivered by 4 PF trains motors Realistic suspension - High-gearing solid axle in the back and McPherson suspnsnion in the front Here's the current progress: The gearbox has a total of 4 gears. Wave pieces are used to switch between them. Here's a more detailed view of the setup. As you can see, I used a tilted axle for the overdrive gear: Since the wave selector pieces can't cope with high torque, the gearbox is designed to work with high speed and low torque. That is why it will be powered by the fastest currently available motors - 4 PF train motors spinning at over 2000 RPM generating around 10Ncm of torque. The rear axle is an inverted portal design. It' made to be low as possible so that the bed can be placed nice and low. The axle has a total of 1:12 gear ratio in order to get useful torque from the fast spinning gearbox. Double 24 tooth gears are used in final drive because I expect the car to be quite heavy. So that's the basic idea for now. I will update the topic as I build.
