Description
Technical field
The utility model belongs to vehicle tyre travel driving unit technical field, is specifically related to one and is applied to vehicle tyre walking hydraulic pressure auxiliary drive.
Background technology
For some class of jobs special-use vehicle, need low speed driving during equipment work, when not working, need high speed transfer.Traditional approach many employings assistant engine fills apparatus for work on driving, and engine in situ is responsible for travelling and is driven, and this type of drive exists engine power surplus, and oil consumption is high, and noise is high, the problem that exhaust pollution is large; Or adopt chassis to install Full-power takeoff additional, utilize in engine in situ power driven and fill apparatus for work, but Full-power takeoff needs special exploitation, costly, and the low speed driving poor performance on mechanical drive chassis.
Summary of the invention
In order to overcome the above-mentioned technical matters that prior art field exists, the purpose of this utility model is, provide a kind of wheel tyre walking hydraulic pressure auxiliary drive, structure is simple, and cost is low, realizes low speed stepless change when working truck works and drives.
The wheel tyre walking hydraulic pressure auxiliary drive that the utility model provides, it comprises power hydraulic system and part-time case, described power hydraulic system comprises Hydraulic Pump, HM Hydraulic Motor, fuel tank, pipeline, valve, described Hydraulic Pump is arranged on vehicle chassis, be connected with the power takeoff of vehicle chassis change speed gear box, power is obtained by the power takeoff of chassis speed changing box, and by transmission of power to power divider device, the front output shaft of described part-time case is connected with output shaft of gear-box, rear output shaft is connected with back axle, and input shaft is connected with HM Hydraulic Motor.
The wheel tyre walking hydraulic pressure auxiliary drive that the utility model provides, its beneficial effect is, adopt general parts, realize low speed stepless change when working truck works to drive, utilize in the power driven of engine in situ simultaneously and fill equipment, high speed transfer when not working, upper dress work and chassis travel and are independent of each other, whole system structure is simple, and cost is low.
