Abstract
The invention relates to a lever-type hydraulic pusher which is applied to a hydraulic gear motor and is characterized in that an eccentric wheel is fixed on a spindle, at least two lever shafts of a crank lever are fixed in a box body, a large rolling wheel arranged on a power arm of the crank lever is tangent to the eccentric wheel in contour, and a small rolling wheel arranged on a resistance arm of the crank lever is tangent to a piston rod arranged on a plunger pump. The lever-type hydraulic pusher can be applied to industries and products including automobiles, electricity and household appliances, pushes the plunger pump to work by aid of the crank lever, achieves the purposes of improving power and saving energy consumption by inputting large pressure and flow into the hydraulic gear motor, is simple in structure and wide in application, and reduces pollution.
Description
Technical field
The present invention relates to a kind of for the lever type hydraulic propulsion device on hydraulic gear motor.
Background technique
[0002] the present invention relates to a kind of for the lever type hydraulic propulsion device on hydraulic gear motor.
Summary of the invention
Purpose of the present invention will provide a kind of energy continual incoming pressure and the flow of providing exactly, and can in equal power situation, improve the lever type hydraulic propulsion device of hydraulic gear motor rotating speed and moment of torsion.Technological scheme of the present invention is such; A kind of lever type hydraulic propulsion device, formed by casing, plunger pump, oiling valve, outlet valve, main shaft, it is characterized in that being fixed wtih on main shaft eccentric wheel, have at least the lever shaft of two crank levers to be fixed in casing, big roller on the power arm of crank levers and eccentric wheel profile are tangent, and the trundle on the resistance arm of crank levers and the piston rod of plunger pump are tangent.the power arm of crank levers of the present invention and the roller on resistance arm are tangent with the piston rod of eccentric wheel wheel rim and plunger pump respectively, when main shaft band movable eccentric wheel rotates, under the effect of eccentric wheel profile, the power arm of the big roller driving crank lever that contacts with the eccentric wheel profile moves back and forth take lever shaft as fulcrum, the piston rod that the other end resistance arm of crank levers also drives plunger pump moves back and forth, make oil outlet on plunger pump to outlet valve delivery pressure and flow, pressure and flow that outlet valve is inputted in the hydraulic gear motor through oil outlet tube, the motion of driving hydraulic gear motor.Because the power arm of crank levers is grown, resistance arm is shorter, to the Driving force increasing of plunger sucker rod, make pressure and the flow of plunger pump output also increase, just can improve hydraulic gear motor rotating speed and moment of torsion.Due to 12 plunger pumps being installed in the lever type hydraulic propulsion device, by eccentric rotation, make 12 gapless runnings of plunger pump, just sustainable continual to hydraulic gear motor incoming pressure and flow, also be converted to enhancing and run well with regard to the kinetic energy that makes hydraulic gear motor.Use the invention has the beneficial effects as follows; The present invention can be used on the industries such as automobile, electric power, household electrical appliances and product, use crank levers to promote plunger pump work, by to larger pressure and the flow of hydraulic gear motor input, reach the purpose that improves power, energy efficient, and it is simple in structure, and applicability is extensive, minimizing is polluted.

Embodiment
In Fig. 1, be fixed wtih main shaft 1, outlet valve 7 and scavenger valve 6 on casing 3.The oil inlet pipe that outlet valve 7 is connected with scavenger valve respectively at hydraulic gear motor is connected with oil outlet tube.Be fixed wtih six plunger pumps 28 round main shaft 1 on casing 3, there is string oil pipe 8 to interconnect between every two relative plunger pumps 28, piston rod 27 actions when one of them plunger pump 28, when promoting in-oil cylinder hydraulic oil to outlet valve 7, the negative pressure of its plunger pump 28 interior lower ends adsorbs by the pump oil of string oil pipe 8 with another plunger pump that is connected 28 interior lower ends, make the interior lower end formation of another plunger pump that is connected 28 negative pressure, its piston rod 27 is adsorbed return under negative pressure state.Six crank levers 15 are fixed on casing 3 by lever shaft 17, and the trundle 21 on the resistance arm 19 of crank levers 15 contacts with the piston rod 27 of plunger pump 28.
In Fig. 2, eccentric wheel 2 is fixed on main shaft 1.The lever shaft 17 of crank levers 15 is fixed on casing 3, and the big roller 18 on the power arm 20 of crank levers 15 is tangent with the profile of eccentric wheel 2.
In Fig. 3, two groups totally 12 plunger pumps 28 and crank levers 15 symmetries be arranged on the both sides of eccentric wheel 2, the big roller 18 of 12 power arms 20 is tangent with the profile of eccentric wheel 2.
In Fig. 4, on crank levers 15, dynamic arm 20, resistance arm 19 and lever shaft 17, have trundle 21 on resistance arm 19, and big roller 18 is arranged on power arm 20.
during operation, when main shaft 1 band movable eccentric wheel 2 rotates, under the effect of eccentric wheel 2 profiles, big roller 18 at the ultimate range circumcircle track place of eccentric wheel 2 profiles is subject to the effect of power, the power arm 20 of driving crank lever 15 moves back and forth take lever shaft 17 as fulcrum, the piston rod 27 that the trundle 21 of the other end resistance arm 19 of crank levers 15 also drives plunger pump 28 moves back and forth, make the in-oil cylinder hydraulic oil of plunger pump 28 oily to outlet valve 7 output hydraulic pressures through oil outlet, pressure and flow that hydraulic oil is inputted in the hydraulic gear motor through oil inlet pipe by outlet valve 7 again, the motion of driving hydraulic gear motor.Hydraulic oil in hydraulic gear motor is again in scavenger valve 6 is got back to the angle of rake closed fuel tank 3 of lever type hydraulic.Because the power arm 20 of crank levers 15 is longer, under equal power, the Driving force of plunger pump 28 upper piston rods 27 is also strengthened, make pressure and the flow of plunger pump 28 outputs also increase, just can improve hydraulic gear motor rotating speed and moment of torsion.Be symmetrically installed with 12 plunger pumps 28 owing to dividing two groups in the lever type hydraulic propulsion device, the driving of the big roller 18 that the rotation by eccentric wheel 2 and 12 and eccentric wheel 2 profiles are tangent, 12 plunger pumps 28 are turned round fast, just sustainable continual to hydraulic gear motor incoming pressure and flow, also be converted to enhancing and run well with regard to the kinetic energy that makes hydraulic gear motor.
