Description
Technical field
The present invention relates to a kind of transmission device, especially a kind of machinery, hydraulic combined transmission device.
Background technique
A lot of engineer operations need carry apparatus for work while going, carry out each item construction operation, like sweeping machine, reaper etc. with automobile chassis.The power transmission of some of them apparatus for work is to realize that through a mechanical transfer case powered vehicle is gone and apparatus for work work simultaneously by a motor, such as the transmission device of reaper.But because sweeping machine etc. needs conversion travelling speed constantly in the process of moving, changed engine speed when speed change is gone, will cause operation quality to descend, so apparatus for work such as sweeping machine can not use this method for power transmission.
At present, the power transmission of similar sweeping machine apparatus for work has two kinds of solutions: the first is used twin-engined configurations, and a motor is used for powered vehicle and goes, and another motor is used to drive the apparatus for work construction operation; It two is that monomotor connects hydraulicdriven configuration, by the oil hydraulic pump of a plurality of series connection of engine-driving, realizes respectively that through controlling a plurality of oil hydraulic pumps, oil hydraulic motor powered vehicle is gone and the apparatus for work construction operation.But the oil consumption of twin-engined allocation plans is high, the discharging high, and it is big that twin-engined installations take the space of special-purpose vehicle, and the phenomenon of low load with strong power generally can appear in this configuration.It is low that monomotor disposes the total transmission efficiency of hydraulicdriven scheme, and the efficient of the Hydraulic Power Transmission System relatively efficient of machine driven system hangs down 15～25%, and transmission efficiency is low, oil consumption is high.
Driving mechanically operated truck goes on bumpy highway section, mining area; The degree of injury of motor, mechanical clutch, speed changer, ransaxle is quite a few times that on flat road, go; The automobile of driving the stepless speed changing with hydraulic transmission characteristic in this case is laborsaving but also province's expense not only; But should mechanically operated mechanism during transport driving on flat road when truck, transmission efficiency is high, speed is fast.Market demand part automobile has the drive characteristic that adapts to different road conditions, the automobile chassis transmission device that is suitable on similar mining area, desert, ice and snow road, soft field, having good rideability on same car.
" hydraulic transmission discussion " (author Wu Kejin; " hydraulic industry ", Ministry of Machine-Building Industry's hydropneumatic industry is sponsored, total the 26th phase; Publication on May 15th, 1), delivered the hydraulic pressure-mechanical dual power transmission of external certain a kind of truck of company.The hydraulic power stream of this mechanism is realized that by axial piston bidirectional variable oil hydraulic pump transmission constant displacement hydraulic motor mechanical output stream is implemented by a simple planetary drivetrain.The task of mechanical output branch is: the power with a member input in this mechanism is divided into two-way output, and the energy that hydraulic transmission, mechanical transmission two-part power circuit are transmitted converges the energy output after will being converged by output member then.The main operator of this transmission has 3: the variable bar of variable displacement pump, clutch L1 and L2.The process of this scheme transmission has three phases: the phase I is low-speed forward and retreats, and clutch L2 separates, the cutting machine branched power; Clutch L1 engages; The whole revolution of planet row, this stage realizes advancing and reversing through the manipulated variable bar, and this stage is hydraulic transmission; Second stage is to increase the speed of a motor vehicle; Under the low-forward range operating mode; Pump delivery transfers to and clutch L1 is separated behind the maximum position and clutch L2 is engaged, and planet arranges beginning work, again with the variable bar of variable displacement pump by positive maximum position; The direction that reduces to discharge capacity is gradually regulated, and this stage is hydraulic pressure-mechanical compound transmission; Phase III is further to increase the speed of a motor vehicle; Regulating method is, the variable bar of pump moved to negative discharge capacity direction by zero-bit, because the swashplate angle of pump has changed direction; Thereby also counterrotating of oil hydraulic motor; The variable bar of progressively regulating until pump reaches negative discharge capacity maximum value position, and this truck has just reached maximum forward speed, and the phase III also is hydraulic pressure-mechanical compound transmission.The deficiency of this hydraulic pressure-mechanical compound transmission scheme is: (1) phase I is hydraulic transmission, and its transmission efficiency is low; (2) there is circulating power in the power flow direction of second stage; (3) hydraulic power stream constantly changes with the ratio that mechanical output flows in the phase III, and the total transmission efficiency after converging is unstable; (4) operating method is complicated grasps with being difficult to, not general with the general operation main points of general-utility car, makes the driver operate miss occur easily and causes security incident.
