Why Do Walk Behind Road Roller Tractors Choose The Front Powertrain?
Why is the special tractor powertrain of impact walk behind road in front? What are his advantages? First of all, we need to know what the front end of the tractor powertrain for impact roller refers to? The following roller company Xiaobian take you to understand it.
Front mounted power assembly of special tractor for impact walk behind road refers to that the power assembly (engine, gearbox, torque converter, radiator, etc.) of tractor is arranged in front of the cab. This design is rare, and it is mainly used in high-power 380 HP / 360 HP special tractor for impact roller (hereinafter referred to as 380 tractor).
Friends who know the construction conditions of plum blossom impact roller all know that when the impact roller rolls several times before the impact, the working condition is the worst. The huge impact force has a large settlement on the subgrade, which is wavy, and the vehicle is bumpy.
The power assembly of special tractor for impact walk behind road is rear mounted (see the figure below, similar to the design of loader, etc.) the center of gravity of the whole machine is back, and then the traction force is trigonal or pentagonal to impact the roller, which makes the whole set of equipment heavy at the back and light at the front, with large resistance and relatively bumpy.
Schematic diagram of impact rollerThe tractor's power assembly is rear mounted, the weight configuration of the whole tractor is more reasonable, the balance is good, the running resistance of the equipment is reduced, the bumpiness degree is alleviated, and the fatigue strength of the driver is reduced.
Powertrain front tractor380 tractor is a mature model which is completely independent designed and improved on the basis of 320 special tractor (conventional power train rear). From the appearance of the model to the repeated improvement of internal configuration, it is a professional design for the special working conditions of impact roller construction. The technology of this model is mature and the performance is stable.
Power unit rear mounted tractorAt the same time, the tractor radiator is also transformed into the forward wind structure, the heat dissipation effect is enhanced, and the continuous operation ability of the equipment is improved to a certain extent, so as to meet the construction requirements of the continuous operation of the impact in the airport, reservoir and other large operation range.
Forward air radiatorIn addition, compared with 320 special tractor (conventional power train rear mounted), the original front steering hinge structure is changed into rear mounted, which is equivalent to the rigid link between the power train device, drive axle, etc. and the impact roller is changed into an active link, greatly reducing the impact of the huge recoil force of the impact roller on the traction power train, drive axle, etc Direct injury of the implant.
Of course, the tractor has more than just the above advantages, its professionalism, rationality of some other optimization design, make it less and less welcome!
