Basically, I have been trying to build a vehicle with a friend for a while now and I am having a bit of trouble trying to understand how gearing and torque should be done. I understand the basics of gear ratios and how they effect torque, but haven’t had any luck with it in Gmod. What I am trying to do is pretty simple. My engine is just a motor wheel that will try to run at the same rpm at all times, and I simply want to have a gear for torque, and a second gear for speed. Perhaps even a third gear between. I know how to do this in the game, but I have had no luck with any of my results. For testing purposes, I have created a few vehicles with a single motor giving power to each wheel and tested how far they can make it up an incline. After, I would attach a small gear for input, then a large gear (at least 3:1) as output that would turn the wheels. I noticed no real difference in how far it could get up the same incline. I could give the motor wheel more torque, but that would not help either as it would just increase wheel spinning out or front end of vehicle popping wheelies. I’m really not sure if I am doing this right or if I am missing something.
Heres a poor illustration of what I was testing with. A 500kg 24" motor wheel with 100,000 torque pulling 4 120inch monster truck tires through a bsocket differential and 2000kg body weight. With no gears, I could get around 25mph and 1/4th up an incline. With a 3:1 gear ratio with same setup, I was accelerating faster but I was still only making it about 1/4th up an incline that was not very steep. Any modification of weight for motor/gears or more motor torque just made the vehicle do wheelies or spin out.
Any help at all would be appreciated!
