Construction
The RC car suspension and chassis portion of the project is constructed in four sub assemblies Front Suspension, Rear Suspension, Front Hubs, and Frame. The sub assemblies contains different sets of parts that connect together with fasteners or pins. The sub assemblies will then be connected to the frame sub assembly.
Over the course of the project many methods of engineering were used to construct the RC car. The project was designed using aspects of dynamics, statics, strength of materials, and mechanical design. Stress equations were used to make sure the project would meet the requirements. Various textbooks were used to apply the necessary engineering methods.
Most of the RC cars parts were manufactured by Colton Hague and Tucker Odegaard. The parts that were not manufactured were bought from a retailer. The suspension and chassis were designed and analyzed from Colton Hague’s residence. The parts of the suspension and chassis were manufactured within the limitations of US Scales shop.
The primary manufacturing methods used were laser cutting, machining in the form of turning, and drilling. Precise and accurate measuring tools had to be used to do the layout of the bolt holes on all necessary parts.
The Chassis plate, Front Shock Tower, Rear Shock Mounts, and Suspension Arms after laser cutting.
The layout of the parts on the sheet of 6061 T6 aluminum on the laser cutting software prior to cutting the parts out.
The parts getting cutout on the laser cutting machine.
The parts being prepped for layout so that they could be drilled for mounting holes. Dye was used so they could be scribed using a height gauge.
Drilling the shock connection holes on the suspension arm.
Assembly without connecting the front shock tower, rear shock mounts, and the turnbuckle mount. The assembly was to double check that all parts would line up as planned prior to drilling the main component mounting holes in the chassis plate.
The main component mounting hole prep for the chassis plate. Dye was used to scribe marks with height gauge so the holes were drilled in the correct locations.
Pre assembly of the motor mount and transmission to double check that the mounting holes on the chassis plate were in the correct location.
