Hicas (electrically Controlled) System

[slipperywhenboosting]

Hey Everyone,

I am implementing a system similar to the HICAS system but on a formula SAE team race car, I was wondering if anyone could take a photo of the actuators for me and the whole system at the rear. I am trying to know whether or not i could use the actuators and motors from one of the skylines or 300zx to implement on the rear wheel steering.

Even better, if some one in the north eastern Adelaide area has one sitting around off of the car (since they often crap themselves) for me to look at breifly.

I am also still trying to see how it actually turns the rear wheels, any info or photos will help. i have been looking for photos for a while but cant find any decent ones on the net.

This is just the electrically controlled HICAS system i am interested in (not the hydraulic).

Not sure which skylines they were in but they were in the 300zx from 94 to 96.

Post any info on it as it may help other people that are having problem with their hicas system.

Cheers

search for "Hicas Lock bar". That sould give you some pics.

Ps, why do you want Hicas. Most people here get rid of it for good reasons...

Umm I think alot of people are going to ask... why you'd want Hicas

Most people remove it for race applications on skylines

Hey, that undercar pic i just found before reading this, must have missed that earlier. That helps a little. Cheers. We are encorporating 4ws (3 degrees on rear) on the car this year and are investigating the best way to get the car to turn and manuevour because our car sucked last year. I have been told to do it using electrically controlled solenoids, dc and/or brushless dc motors but have been struggling to find suitable (light) motors so far and thats why i am looking at the hicas system. (both for ideas and for parts) the main idea is to use the 4ws for tight corners where our speed would be less than 50km/hr because the tracks we race on have lots of them. (most tracks and roads skylines drive on dont so you may as well get rid of it.

Cars such as skylines are driven everyday mostly and these hicas systems dont last that long (ie less than ten years), and this car will be driven for a few hours each weekend and highly maintained plus I am hoping to do a better job at it then nissan engineers. (But they have produced some sweet cars!!!)

Thanks for the help so far but more would be awesome. (the hicas lock bar search just had replacement bars to get rid of hicas)

I still want to see inside of one of them units to see the gearing on the end of the main black motor.

also does anyone know how that motor is connected to the steering, im guessing just a spline but not sure.

Perhaps put a WTB post up in your relevant state. For an electric hicas system. Some people removes theirs entirely to save on weight. So they'd have them just sitting around somewhere. You might even get hold of one for free Then you can open it up and mod it all you want

You have a point there Dan, if anyone want to give me one to play with, i would be more than happy to pick it up in the adelaide metropolitan area. I am still wondering if it would be useful but i might be able to borrow one off of a contact at a japanese wreckers.

If I found out that it would be useful, i would buy one. Does anyone know how heavy this motor is?

If anyone reads this and has done something similar before, send me a PM, i would be very interested in speaking with you.
