Such mechanical traction bulldozer determine the level of work productivity

Because swamp hydraulic crawler dozer In the course of its work means a state of passive state, the need to travel agencies traction down to advance the work, so it is called mechanical traction. All towing vehicle drive system to withstand traction load working device, which is a dramatic change, fluctuation of non-stationary random load; swamp hydrostatic dozer towing vehicles generally no job quality requirements, and therefore does not require the stability of the work, but the pursuit of adaptive coordination (to achieve this speed and load capacity between mainly depends on the performance of the travel control system ), the purpose is to make full use of engine power, improve operational productivity, reduce specific fuel consumption, the pursuit of power, economy, job productivity. Thus for this type of traction bulldozer machinery, the travel drive system and with control system performance are important factors exert influence bulldozer operating performance, determine the level of work productivity, we can see on the bulldozer with the drive system and with the control system Research is very necessary and important.

Construction Machinery walking transmission currently there are four ways that the mechanical transmission, hydraulic transmission, hydrostatic transmission and power transmission. Wherein the hydrostatic transmission compared to other transmission mode has its unique advantages, which in the past few years more and more attention in order to be widely adopted.
