After a long time lurking, I finally found time and space to pick up building myself :classic: I picked up a 42009 and 42023 to supplement my brick-based Technic collection from the '80s and '90s with some modern studless. But considering my collection, my building style will be mostly "bricked".

I was inspired by Grazi's tow truck and the trucks of 2LegoOrNot2Lego. Specifically, I wanted to built a realistic truck with suspension, drivetrain, etc.

The skills of aforementioned gentlemen are out of reach for me, but nonetheless I'm quite proud of my creation:

I went a bit overboard with the features:

  • Suspension on all axles
  • Driven rear live axles
  • 4-speed manual gearbox (based on this one from Sariel)
  • 6-cylinder inline engine (hood and bullbar can be titled for access)
  • Front axle controlled with HOG wheel on cab
  • Working steering wheel inside cab
  • Motorized winch
  • Motorized double compressor with two airtanks and automatic shut-off switch

It's all a bit tight, but it all works well without illegal construction techniques. I'm not entirely happy with the linkage for the axle suspension: there is too much play around the vertical axis. Also, if you drive the truck backwards over a bump, you lose the front axle :sweet:

Looks good :classic:

Would the suspension on the rear axles be able to be used as a single rear axle?

Thanks.

Yes, the two axles are identical can be used independently. Since I did most of the prototyping in LDD, I might be making instructions for this model if there is interest :)

Sounds good to me, how long do you think it will take to post the LDD file? I just so happened to be searching for a single axle suspension for my latest project when I came across this.

I have attached the .lxf to this message, but with the note that this is my raw prototyping model. Many parts are missing or substituted with "placeholders". The drivetrain is complete though, so I hope it can help you. Let me know if I can help.

It's the middle of the night for me so I'll fill you in on how I go in the morning.

If you only need one axle, you can also use a 5x7 frame instead for the axle base. This gives you space to add a second Panhard rod, which should make the axle stay in place better. (I needed the drive axle between the two axles to tilt when the two axles are not at the same level, so I couldn't use the 5x7 frames.)
