Manual Transmission Demonstrator

Here is a simulation of a 5 speed manual (Dual Clutch/Sequential Gearbox, since there's no manual clutch) transmission within a Front Engine, Real Wheel Drive Longitudinal Drivetrain. It is design to simulate the functional behavior of such.

This system utilizes a set of Engines, Pistons, and Drive Wheels to carry out this function. For every gear there is an Engine, Piston, and Drive wheel assigned to it. When that Gear is selected via moving the VTOL slider to its position...
1) The Engine is Activated
2) The Wheel connected to that Engine is Powered
3) The Piston lowers that wheel to where it has grip.

The Wheels exploit a glitch where flattening them creates a space of collision below. This is to make them easier to hide in a car body.

For those without basic understanding of transmissions, Lower Gears (Gear 1, 2) bring higher acceleration but limited Top speed, Higher Gears (Gear 4, 5) bring lower Acceleration but greater Top Speed. From Gears 1-5 you go incrementally from High Acceleration and Low Top Speed to Low Acceleration and High top Speed.

Controls

• Throttle for throttle, Roll for Steering.

• Use the picture below for reference in operating the transmission. Lower Gears have a higher Acceleration while Higher Gears have a higher Top Speed.

• Start in first gear and work your way up as you gain speed, the fourth and fifth gear have an exaggerated low acceleration in order to show the differences in gears, so you'll come off sluggish if you try to accelerate in the fifth gear.

Subassembly Use

• Grab the Assembly by the forward most engine and pull off, you will take off the entire thing and can save it as a subassembly.

• To install into your car, attach via this same engine and nudge it into place. Nudge and scale down any of the parts where needed.

• If you want a front wheel drive drivetrain, simply move the drive wheels to the front axle. For AWD, make one copy for each piston and Drive wheel, attach, and position over the other axle.

• Adjust the vertical position of the drive wheels so that they will deliver no power unless their gear is selected and their full power when that gear is selected.

Important: Due to SP being stupid if you save as subassembly it will come out of subassemblies without the wheels being powered by any engines. Thus you will have to manually set the wheels to be powered by the engines again.

Adjustments

• Two main parameters should be tweaked when adjusting the transmission: Max under the InputController of the Engines, and maxAngularVelocity within the Resizable Wheels.

• Max affects Acceleration for a selected gear

• maxAngularVelocity Affects the Top Speed for a selected gear.

• Set Max high and mAV low, for lower gears. Do the opposite for higher gears.

• To set the car's Total Horsepower, adjust each engine to have the same desired Horsepower.
