Post 21: Considerations about the 3 wheeler chassis design

     The problem with the chassis design I proposed with an offset main "beam is that as it gives the driver more space, it reduces the space for the passenger, which means that accommodate a passenger, the body would have to be even wider than the Lotus 7... 





     So one big question to answer is: build a wide two seater, or a narrow one seater?

  Unless of course I use a surround space frame and no central beam at all. The reason for the central member of the frame in the Lotus 7 design is that it is a 4 wheeler with a rear live axle, and a shaft between the transmission and the axle. The purpose of the center well is to house the shaft which moves up and down with the wheels. Now, in our case, the shaft does not move up and down, and if the engine and the rear wheel attachment point are low, it will barely stick up from the floor of the car
