[WIP][MOC] Chassis: 2020 Rollce Royce Phantom EWB

Recommended Posts

Hello everyone! In these hard times I began my old dream to come true - I have started developing a car. This is definitely not a sport/super/hyper car. My aim is to build a luxury sedan. Brand will me mentioned later, I assume after the chassis with drive train will be done (if it would).

As for now I'm going to build fully manual version with advanced realistic suspension with pneumatic brakes,, 4WD (actually original has only RWD, but full is more interesting and complex), interesting V/W 8-12 fake engine and rotating gearbox shifters on the steering wheel (initial and genuine idea by @Charbel), detailed interior.

  • And from the very beginning I've faced with difficulties:
  • Those ball-joints are very hard to rotate, the route from the steering rack to the wheel should be the strongest and the simplest in one time.
  • Still no idea for the rear brakes implementation.
  • No room for the fake engine prototype. I want to use regular cylinder parts, but with the crankshaft from the 42078 set (as example).
  • Too hard to place front drivetrain, steering axle, gearbox and gearbox shifters. At my point I think I need 100*100 studs place to handle all this.

I'm afraid I'll have to refuse from the front driving feature to handle all other modules. But who knows.

And the last fear is the political situation in my country, I don't want to discuss it here, but the mood is very sad and I can be repressed anyway, though.

Allright then, if removing front driverain it will give me a lot of room between the front wheels and I can make an attempt of housing the W12 there...

Don't give up so fast on everything.

Just idea on which I'm workng now, maybe something similar can work for You. Yes, You won't be able to use dogbones

And then for top connection, maybe this combinations is possible

If you want to build a Bentley (or a VW Pheaton) you'll have to find a way to squeeze in the gearbox without compromizing the rear seats, because these are very important on luxury cars like this. Under the rear seats has worked quite well for me in my R32 GT-R :wink:

For the brakes you could compromise and put them on the prop shaft. Certainly for the rear.

That's a great idea.

I think that you shouldn't leave the steering out:

  • Go for a V8, it's smaller...
  • Maybe you'll have to use a "fake" engine

But please, put all in. They are both very important parts when you want to build a sedan, especially a luxury car.

Somewhere on this forum a guy built an epic people carrier a while back that had so many features you’re looking for. I’d search it out and have a look if I were you.

Hello!  Oh, susprisely,  topic hasgreat responce.

I have rebuild front suspension a litle bit - a replace dogbons for regular steering arm, sterring became much smooother! Thanks @Jurss!

As for now chassis has connected AWD, luckily I was able to rebuild front drivetrain and now gear connections are strong without undensity.

Then all four hubs has connected pneumatic cylinders - this caused rebuild of the rear chassis and rear hubs.

Now I will investigate a gearbox and consider taking someone's decision as a basis because I won't develop my own - my weak point is gearboxes and differential's advances properties.

 

I will upload several photos a bit later.

Hello! Here a have some updates. It may seems nothing changed, but actually model has several major udpates.

 

General chassis view. Now in scale.

Front suspension: I've replaces those dogbones and the steering becomes much smoother! Now I have to handle steering anywhere...

Rear suspencion also changed - I added brakes and make the axle thicker 2 studs.

And here is the model "as is":

Axle with yellow knob is a gear shifter - it's suppossed to be connected anywhere.

Fake V12 has dravt connection to the gearbox output.

The gearbox itself is the moderated Didumos one. I make it AWD. https://rebrickable.com/mocs/MOC-16088/Didumos/sequential-8-speed-transmission-tunnel-with-rotary-catches-and-8-to-1-gearblock/#details

So in the theme of the chassis I still have two problems - how to handle steering rack - I have a total lack of the room for the steering axle... and how many attempts should i need to connect gear shifter to the steering wheel... 

And it's time to call the project - 2020 Rollce Royce Phantom EWB

Looks interesting!

I like the effort put into the suspension design, and the pneumatic brakes are fairly unusual as well! Maybe I should try to collect enough small cylinders to build a similar system.

Good work!
