Can a 250 cc Honda Engine Be Integrated into a Car with a Button Gear Shift?

[nikhilesh]

I've a gearbox from a 250 cc Honda engine. The pattern in one down and four up. This engine will be integrated into a car, so the changing of gears will be difficult with the foot pedal. wouldn't it ? :) . So i decided to integrate a small motor to the gear shift pedal so that it can change gears. Is this feasible?
Will it work?
any answers?

what about hydraulic shifting? Like using a paintball CO2 bottle or those 12 gram CO2 cartridges.

Is weight a concern? Would the motor and its power supply be lighter than a CO2 shifting system?

It shouldn't be hard to add a linkage from the gearbox to a regular floor-mounted stick. A cable system would probably be easiest.

SELENOID A DOUBLE should work to shift up and down
trick is to match it to the effort required
not too strong or weak
but there are a lot of car [12v] selenoids in use
a trip to a junk yard should get you a bunch

 

[nikhilesh]

what exactly is a selenoid? what's it used for in a car?

 

[nikhilesh]

and the idea behind the motor, is to make the gear shift with a button or paddle... while still using the clutch with the other hand... all this on the steering wheel

a selenoid is a el-trick magnet that moves something
a double throw selenoid moves in and out depending on current direction
most are switches but some move things like on a starter or a air flow flap

You may have better luck searching for a 'selenoid' if you spell it 'solenoid'.

Personally, I think this sounds like the kind of application where you'd be much better off with a mechanical linkage of some sort. Danger's suggestion of cables would be worth looking at, or (depending on packaging constraints) a simple system of pivoting rods.

This is an excellent way to do it. I recently saw an internet video that had just this setup in a dune buggy with a rear-mounted 1200cc crotch-rocket engine in it. There was a "shifter" next to the driver, forward was shift up and backward was shift down.

Using a solenoid is extra weight and extra trouble. I too would go for the mechanical shift linkage approach.
