Torqueconverter

Torqueconverter used in SD7 bulldozer is power separating hydraulic-mechanic type.

Transmissionassembly

Itintegrates center drive, transmission and speed changing control valve into onecomponent. It can be assembled or disassembled as a assembly or as a part. Itis very convenient to service. Transmission is multi-stage planetary gear driveto realize modular assembling and disassembling. The shift can be changed among1st gear, 2nd gear, 3rd gear forward or reverse rapidly, throughmulti-functional control valve.

Steeringand braking clutch

Steeringclutch and braking clutch are adjustment free, oil-type , multi-disc clutch.The braking clutch is pressed by spring, separated hydraulicly, constant meshedtype. Steering clutch is hydraulic pressed, non-constant engaged clutch. Theaction of steering and braking is combined, operation manually to realizesteering slowly, sharply and braking. The braking of entire machine can berealized through the pedal. Parking braking rod is designed to keep theundercarriage system in braking condition when starting the engine andguarantee the machine not to slip on slope when starting the engine.

Finaldrive

Finaldrive is two-stage planetary reduction gear mechanism. It is mounted at outsideof steering and braking clutch. Combined sprocket segment is very convenientfor assembling, disassembling and service.

Hydraulicsystem of the machine

Itis composed of oil pump, transmission control valve, steering and braking controlvalve, sequence valve, relief valve at torque convertor outlet, filter andlines.

Mainpump-------------------------------------------------------------------------------------------------------------Gearpump

Oilflow----------------------------------------------------------------------------------------------------------------160 L/min

Rops with air conditioner cab

Thecab is hexagonal thin wall box-type structure. Glass is mounted at sixsides with wide viewing area. Pulling and pushing glass is installed at backside. Air conditioner is top-mounted with functions of cooling and heating. Thestructure of Rop is rigid. It can protect the driver efficiently when thebulldozer is in special condition.

Implementhydraulic system

Implementhydraulic system can control lifting, lowing and tilting of the blade. It alsocan control lifting, lowing of the ripper. It mainly consists of oil pump,cylinder, inlet valve group diverter valve group, oil tank line and controllingparts.

Mainpump ------------------------------------------------------------------------------------------High pressure gear pump

Oilflow --------------------------------------------------------------------------------------------------------------194 L/min

Systemworking pressure-------------------------------------------------------------------------------------------18.6 MPa

Leftand right undercarriage system

Thetrack is triangle shape. The sprocket is elevated. There are two idlers infront and at rear of the frame and seven track roller. Recoil spring andcylinder adjuster is mounted at the undercarriage. The rear end ofundercarriage frame is supported on the pivot. The front end is articulatedwith the equalizer bar. Choosing different undercarriage system according todifferent implement. The customer is required can guarantee center gravity ofthe machine to be at best efficient position. Choosing different width of trackshoe can ensure the bulldozer developing its optimum traction efficiency.

Q:I'm looking to get this motherboard with a SATA 500gb HDD, does this motherboard support SATA III?
any newer motherboards like am3+ socket, should definitely have support for SATA III. But SATA 500gb HDD im guessing is a mechanical drive. And thus cant possibly use sata III lol They may label the drive as SATA III, but it makes no difference anyway. Sata II = 3Gb/s (384 MB/s) Sata III = 6 Gb/s (768 MB/s) a WD caviar black 7200 rpm drive will average 80-140 MB/s read/writes. Even 2 10k rpm wd raptors in raid0 STILL cant even use all of the bandwidth available in sata II to make sata III have a point in the first place. so really unless you have a good SSD, its completely pointless to use sata III anyway. EDIT: also want to add, SATA is backwards compatible. So you can use a sata III drive in a sata II port just fine (or vice versa), tho ofcourse you will get the slower of the 2 speeds, tho like i explained above, it makes no difference anyway. And yes, it has a pci-e x16 slot, so it will be compatible with ANY pci-e x16 graphics card. Its also backwards compatible like sata. SO you can use a pci-e x16 3.0 card in a 2.0/2.1 slot, but will be limited to the pci-e 2.0/2.1 bandwidth. Which is fine unless you are getting multi pci-e 3.0 cards or a really high end 3.0 card. EDIT2: you dont need to put edit, as its clear when asker adds details :P anyway, the gtx670 will be bottle necked by the 8150 and pci-e 2.0 Really i wouldnt suggest even getting a gtx660 (non ti) unless you are running an i5 3rd gen in a pci-e 3.0 slot. Its not that it wont like max games. Like ya, if you get a gtx670 you should still easily max most all games, but having a better cpu (like the i5 3rd gen) in a pci-e 3.0 slot, you will get better fps and resolutions. EDIT3: well the H61 board doesnt support pci-e 3.0 either . you need to get atleast an H77 board. You can drop the i5 to a 3450 and save like $10 which could be put towards an h77 board.
Q:i have contacted cosmi games via live chat but no results for this game bulldozer is the name it was sold on a disc with other games i had it on my pc but i lost all the data on my pc so i lost it for ever can any one help asap
Top okorder / I've narrowed it down to these two CDs. One is just called "COSMI" and the other is "Top 50 Blazing Games." Unfortunately, they're not compatible with my 64 bit OS system so I can't install it. In order to try to see if it is actually from these two CDs, I'm going to have to revive my older OS computer. The thing is I don't want to open my Windows 98 PC up and put in a power supply. If you find out what game it is, please contact me.
Q:A bulldozer pushes a large rock, and the two move forward together. The bulldozer does 1500 J of work on the rock. How much work does the rock do on the bulldozer? Clearly explain your reasoning.
It does less work on the truck then the truck does on it because it is moving forward I'd you gave more information I might be more precise. Of this helped you plz give 10 pts
Q:If I buy a new Sabertooth 990FX board and an FX-8150 cpu.. will I still need to update the BIOS before it will work properly, or do they update the BIOS on new boards during manufacturing as updates become available for them?
No, not unless the board had been sitting in a warehouse for a very long time. They get shipped with the newest available bios.
Q:Guys, I heard from someone that AMD bulldozer FX 8170 is not far away from us. I'm looking forward to this processor, anyone know the release date? Please help! Much appreciated!
Not official but it is rumoured for October 12th
Q:AMD bulldozer fx 8150 AMD raedon 7970 with a few slots for hard drives I'm going to combine them with raid 0 but I haven't decided how many or how much memory
One that has a socket that the cpu will fit in. (hint : AM3+)
Q:Which performance is good, bulldozer or I5?!
1, as compared to FX4300 and i5 4430.2, FX4300 clocked at 3.8GHz, core frequency maximum 4GHz, i5 4430 3GHz, the highest core frequency is 3.2GHz, i5 can be seen at a slightly lower frequency, but this is not the performance, but the architecture of CPU, FX series of CPU using the module architecture, single thread performance is very weak, compared with i5 4430 Haswell architecture, single core is stronger than FX4300, as well as many nuclear FX4300.
Q:we need to get bulldozer off island on the frozen lake. Need to know how much ice will support that kind of weight. Bulldozer must weight about 1600 pounds
The bulldozer only weighs 1600 pounds? If so, 8-12 of ice will reportedly support it, although I'd feel much safer with at least 2-3 feet. I suggest you try to verify the dozer's weight beforehand!
