lmdesigner42 Posted May 12, 2020 Posted May 12, 2020 Hello everyone, this is the entry I'm working on for the small car contest. It started with an idea for a narrow steered and driven axle, around which I'm developing a small monster truck-style model. Features planned at the moment include: AWD Four wheel steer Suspension Oversize V8 fake engine My first design for the suspension didn't work, as the springs (removed in above picture) in the extended position stressed the CV joints too much. The wheelbase was also too long for the form factor I wanted, so I definitely need to redo the suspension. The tires are 20x30, part number 6581 which according to Bricklink have an outer diameter of 49.6 mm so they fit for the contest. They're basically the same size as the 49.5 mm tires, but they fit the axles better and in my opinion look better for a monster truck. Another picture showing the axle width: Feedback and comments are welcome. Quote
lmdesigner42 Posted May 19, 2020 Author Posted May 19, 2020 Progress update: I redesigned the axles to use 6L links, and added soft 6.5L springs. The spring mounts only have 1 degree of freedom, but there is enough play in the frictionless mounting pins to allow the axles to rock side to side easily. The wheelbase is also 4 studs shorter, giving a better appearance, but this required replacing the rack and pinion steering with a set of 9L links. The engine also shrank from a V8 to a V6 to give better placement for the spring mounts. Significant progress has been made on the bodywork now, just need to finish the front end. The steering was a little challenging to fit, a half-stud offset on the shaft was needed for proper geometry and range of motion. And it's done! Nice, clean (IMO) red and black bodywork with a few system parts for details. A V8 is still possible, but the V6 fits better in the hood space. Functional 4-wheel steering: Articulating live-axle suspension: Total height about 15.5 studs: This "small car" is ready for the contest! Quote
