ChasSomT. Posted November 25, 2010 Share Posted November 25, 2010 Purely 'academically', does anybody on here know how the braking system works on the Bulldog/fv432Mk 3. I know the steering is by 'Yoke', and totally separate. Just out of interest :-) Chas. Moved from 'Legislation' thread (Think I just got away with not being shot!)

andym Posted November 25, 2010 Share Posted November 25, 2010 Two sets of discs, both internal to the gearbox/steering unit. One set does the steering, the other both the foot brakes and the parking brake, although they have independent linkages external to the box. Unlike the CVR(T), the parking brake can be applied and released gradually. Andy Quote Link to comment Share on other sites More sharing options...
Marmite!! Posted November 25, 2010 Share Posted November 25, 2010 (edited) Found this snip Crews at the controls of the Bulldog were also unanimous in their praise. They believed it would inspire confidence among troops on the ground. Rfn Paul Sapsford said: “This vehicle is very good news. It is a lot easier to drive than the old FV432 and has independent steering and brakes.” & talking about the old FV432's Many of the subsystems are no longer supportable and its drive train, braking and steering system no longer meets the latest European regulations. http://www.army-guide.com/eng/product1031.html Edited November 25, 2010 by Marmite!!

Andy8419 Posted January 1, 2011 Share Posted January 1, 2011 Not sure if this helps but I have a VT Land presentation with the following extracts: 1. -TRANSMISSION -The X200 4C gearbox is located at the front of the vehicle and can be accessed from the driver’s compartment and from the outside of the vehicle via the gearbox access covers. -It is connected to the engine via a drive shaft to a transfer box. The drive is then transferred through a torque converter to the Transmission. -The gearbox, by means of 4 forward and one reverse gear, provides the drive to the final drives via two output drive shafts. The gearbox also provides a neutral turn facility as well as braking and steering of the vehicle. 2. -Brakes The gearbox houses the vehicle brakes. These are applied by depressing the brake pedal which initially applies the brakes via a braking cross beam, a braking compensator chain and left and right brake apply shafts. Braking is then applied by means of hydraulics within the gearbox. Further application of the brake pedal will increase the brake effort by mechanically enhancing the hydraulic actuators within the gearbox. Secondary Braking The parking brake linkage is independent of the primary brake linkage and attaches to the brake pawls on the gearbox. Apologies for the "messy" text I am still learning how to post to the threads. I do have the presentations (VT Engine Pack Precis, VT General Precis and VT Transmission Precis) and will email or post (if someone tells me how)?

ChasSomT. Posted January 1, 2011 Author Share Posted January 1, 2011 Very interesting,thank you. Does this mean that there are four forward gears, or four gear ranges, as previously? Chas. Quote Link to comment Share on other sites More sharing options...
FLUF Posted January 2, 2011 Share Posted January 2, 2011 cant help with the spec but can provide some photos that maybe of intrest Quote Link to comment Share on other sites More sharing options...
paulob1 Posted January 2, 2011 Share Posted January 2, 2011 cant help with the spec but can provide some photos that maybe of intrest is it possible to fit this into a std 432 or is there a lot of work. As regards current regs, many machines dont confirm to current regs, but if it was acceptable in 1960 it is acceptable today as the rules are not backdated... and to be fair the 432's stop and start and steer as they always have, perfectly fine...although a foot pedal would be preferable to the levers...

ferretfixer Posted January 2, 2011 Share Posted January 2, 2011 The front access hatch on Orig 432's in ONE Piece, on the Bulldog it's TWO & a Bigger opening! Thats just for starters! I would imagine the mounting points for the internals now are also in different postions due to the equipment sub systems differeing shapes. Just a thought......:nut: Quote Link to comment Share on other sites More sharing options...
andym Posted January 2, 2011 Share Posted January 2, 2011 In theory you should be able to modify an existing 430 to Bulldog spec as it was originally designed to be carried out as a field workshop conversion. It was only when they decided to return them to Bovington for conversion that the extra opening appeared in the front hatch to improve access. Note that in a Bulldog the "pack" is now just the engine and transfer box as the gearbox sits where the original steering unit was. Apparently the gearbox has to be dropped in through the engine hatch and then pulled forward into position. Bulldogs also have their 432 final drives replaced with the lower ratio 433/434 units. They're electronically governed to 42 mph for safety and track wear reasons, I was told they managed nearly 60 mph in trials! And Chas yes, four forward gears, one reverse.

andym Posted January 2, 2011 Share Posted January 2, 2011 are they manual then, no semi auto box? Sorry for any confusion - a fully automatic box with four forward and one reverse gear! Andy Quote Link to comment Share on other sites More sharing options...
paulob1 Posted January 3, 2011 Share Posted January 3, 2011 ah okay, but only four gears, that means it must have a shed load more power than the old k60...anyone know how much power it has...hence the monster speeds... Quote Link to comment Share on other sites More sharing options...
andym Posted January 4, 2011 Share Posted January 4, 2011 It's a Cummins 6BTA 250 diesel, similar to that used in the CVR(T)(D) upgrades but with a suspiciously familiar looking set of radiators and hydraulic fan drive. It's also about half a ton lighter than the K60, which must help a bit. Andy Quote Link to comment Share on other sites More sharing options...
oily Posted January 10, 2011 Share Posted January 10, 2011 ....! right!:cool2:, I want a 'new' FV432 Bulldog, now aswell!... only I'll de-restrict my one!:cool2::cool2::cool2: Quote Link to comment Share on other sites More sharing options...
Tankman Posted January 11, 2011 Share Posted January 11, 2011 for work recently i had a very interesting visit to allisons uk main dealer in mansfield mitchell powersystems and the information they had on the 432 mk1/2/3 was immense plus they gave me the crossover part numbers for the filters. definately worth a call sadly the bulldog transmission is still restricted for uk sale.SHAME Quote Link to comment Share on other sites More sharing options...
