    it probably is a gavril subsiduary or a company wich isnt building its own engines as its using gavril engines so either it was once an independent company and got absorbed into gavril or it still is an independent company with close tyes to gavril

    Maybe a little insight into what the different letters is the model name mean.

    D = diesel
    T = IDK, turbocharged?
    40 = length, in feet
    L = low-floor

    I already tried to decipher this, but I said the L stands for long body. Low floor makes more sense.

    yeah low-floor. Bu then again Low-floor buses can't be used anymore due to the disability discrimination act. Maybe a coach with the same chassis and high floor would be on the way. The possibilities are endless :)

    But shouldnt a low floor bus be better for disabled people? As they dont really are that high and you can get more easily in and out

    Yeah, he got it backwards. Just quickly googled it and it says something like any bus over 20 feet in length or over 20 passengers I think is mandated to be a low floor bus. So he got it backwards.

    Also it probably doesnt apply everywhere as we still use them here for school and for long distance travelling

    I am really waiting for what they might come up in regards to the articulated bus (we know how it is going to look). The interesting part wil be the hydros controlled by TC in the main joint. It could be interesting to see what will happen under some extreme conditions that this bus is going to face in BeamNg. I'm certain that it is going to be a low floor rear engined pusher style bus judging by the lack of raise in the window line for the middle of the bus and by some pieces of textures for the middle section that can be found in the files. And by the fact that I think every US articulated bus uses this drivetrain, as for the driveshaft to pass threw the joint it would require to have a raised floor.

    Doesn't apply at all, they are heavily used as urban transport busses all over North America and have been for a good while now, and will continue to be because they are much more ergonomic than a high floor bus. High floor busses are used as coaches primarily because it allows for belly bays where people can store their luggage etc.
    --- Post updated ---

    They never route the power through the joint, as far as I'm aware. The drivetrain is put into the trailing section of the bus. The front section is low floor the whole way back to the joint, the trailing section is low floor until the rear axle back where it raises up to accommodate the drivetrain.



    Also, I don't think they'd even have hydros on the joint, pretty sure its just an uncontrolled pivot joint, that can pivot side to side and up and down.

    Also, also. If you look closely the last 2 windows raise where the floor raises to accommodate the drivetrain, so the front section would have a level window line and the rear the last 2 sets of windows would be raised where the floor is raised.

    Look at the window line on the skin UV map located in the files, the main body of the bus is flat which means the driven wheel are going to be located in the trailer as they're in most of the articulated buses, which requires sway controll integrated into the joint to keep the bus stable in slippery conditions, as you can imagine trailer pushing the bus with no assists could easilly lead to a jackknife situation. I've actually done quite a bit of research on how do articulated buses work as I wasn't sure if they'd do an offocial one and I was gettong ready to make my own.

    In fact some of the articulated buses have a driveshaft going threw the joint, one of the renault busses was rear engined and had both rear and mid axle powered. In theory it would't be that hard to make, but it would sacrafice the low floor for the trailer part and the middle of the bus. From what I've found, both the new flyer df 40 and df60 were aviable with TC, so we might see it's appearance some time in the future.
    What I find quite interesting is that our bus is nearly an exact copy of the new flyer bus.

    Ah, right. The sway control makes sense. You sure its hydraulic though and not just a series of shock absorbers / stabilizers? Semi surprised to hear what Renault has done, but not at the same time. European companies like to overcomplicate the shit out of things for little benefit.


    Really like the fact that its a New Flyer copy actually, very popular bus. My city has used them for over 20 years and they are just starting to switch them out for LFS model Nova Busses and Enviro 500 doubles.

    The thing with just passive damper is that they are passive... They would just make turning harder and still won't prevent jackknife at all... Think about it as an adaptive suspension which is really soft until the bus starts to skid, when it stiffenes stopping the vehicle from a jackknife. Hydraulics are the obvious choice as they work almost instantly.

    Interesting, makes sense. I know Toyota forklifts use a hydraulic stabilizer system for the rear swing axle which can lock it, sorta acts like an anti sway bar but on demand.

    So they must just leave all the valves open so it can move freely until the traction control system tells it to lock up or whatever. Veeeeery interesting.

    I noticed, there is a few fire truck sirens. Does this mean we could get a fire truck under the 'Wentward' brand. It would make sense. In real life, Inernational makes both buses and fire trucks, and Wentward is slightly based off International.

    Most US companies sell their mechanicals to commercial vehicle builders.

    So like a non Newtonian liquid such as oobleck? I’m not sure thas possible right now.

    No, it is just using valves which close which results in stopping the hydraulic piston from moving. It needs to be able to be activated by the TC, which non Newtonian fluid would not do.

    I doubt it would be Wentward. The only bus maker to also manufacture firefighting apparatus was Crown (https://en.wikipedia.org/wiki/Crown_Coach_Corporation), however the Crown Coaches/Firecoaches had a far more truck like frame compared to the DT40L. Most likely we will be seeing a new manufacturer.
