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


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 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.


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

Workingpressure ------------------------------------------------------------------------------------------------------3.1 MPa

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:Several problems about how to operate bulldozer
attention must be focused, work to, for example, see the front light upward immediately press the handle (blade sinking), front on the handle is readily sinking (rising blade).When the bulldozer is not smooth, for example, some hard soil or other obstacles, do not blindly throttle pounded hard push, don't screw up clutch hard hit, also should avoid the side thrust with the shovel soil, so as to avoid serious consequences.A perennial in the wilderness and ground ridge terrain hard and dangerous environment, in the short distance very frequently and, in the high load condition, difficult operation, extremely easy to cause the tractor chassis and blade parts of early wear, deformation, damage, fasteners loose, therefore, in addition to the correct operation outside, on the part of the inspection and maintenance can not have the slightest negligence; dozer blade to keep it sharp, the blunt side can change the surface, both sides can be surfacing serious wear, grinding, or simply change new.
Q:what is the intel equivelent of a amd fx 4100?
It is comparable to sandy bridge i3.i5 will be much faster.
Q:i need help, with science.. im not good at it.?
the answer is A. when anything is at rest it has potential energy, but when it starts moving this changes to kinetic. C and D are wrong because energy can not be created or destroyed just transferred.
Q:AMD8 nuclear bulldozer or Intel 4 Nuclear I5 is better?
Performance is basically flat.I5 more power saving8 cores are more suitable for openingHome recommendation I5
Q:rock music video where 3-4 guys driving a muscle car and hit a bulldozer or something at the end.? ? I'm pretty sure it's not that as only an idiot would forget to mention that a) it's a cartoon and b) the flying sperm.
Q:What would be a good headline for the topic &bulldozing a house with termites&?
&Terminating a Part of History&
Q:name of the bulldozer john died in, in the movie the fighting see bees?
Q:Gearbox Shantui bulldozer sd16 temperature high is going on
Hello You should be automatic, the oil temperature is high, there are several problems. Pressure is not enough, sealing ring wear, pressure valve hairpin, radiator dirty. Check step by step
Q:Will a bulldozer clear stumps ?
yes a bulldozer will clear stumps and level the ground after all the stumps have been removed
Q:Intel Sandy Bridge or AMD Bulldozer?
i might individually look ahead to the bulldozer to come back out as a manner to get a reliable assessment 2 processors. additionally value may be decrease on the sandy bridge 2600k as a manner to compete. So wait!!!
