Specific embodiment
A kind of reciprocating engine lever Variable plunger pump power take-off mechanism described in the utility model, as shown in Figure 1,
Including mounting rack 1.Piston engine is installed on mounting rack 1.Piston engine is existing engine comprising cylinder, piston,
The basic structures such as connecting rod, crank link mechanism, valve mechanism, to ensure to realize the igniting starting of available engine and operate normally
Basic function.Piston-engined piston 3 and first connecting rod 4 are hinged.
Piston engine can only have a set of cylinder 2 and piston 3, can also be symmetrical arranged two sets of cylinders 2 and piston 3.Example
As shown in Figure 1, being set side by side at two side positions of 1 upper end of mounting rack there are two cylinder 2, it is equipped with piston 3 in each cylinder 2,
Two often opposite pistons 3 are connected by same root first connecting rod 4, and the both ends of first connecting rod 4 are hinged with piston 3 respectively.Symmetrically
The two sets of cylinders 2 and piston 3 being arranged can effectively prevent dead point to generate, while engine efficiency can be improved.
Symmetrically arranged two cylinders 2 are one group of cylinder, if power and operation stability is increased, if can also add herein
Dry group cylinder 2.A first connecting rod 4 is equipped between every group of cylinder 2, as shown in figure 3, setting between two first connecting rods 4
There is the first link block 5, the first link block 5 and the first connecting rod 4 of two sides are hinged.The side of first link block, 5 lower end is hinged
Crank link mechanism 6.When engine start, the gear of starter motor drives piston engine by flywheel 7 and crank link mechanism 6
Starting, piston 3 move back and forth in cylinder 2, are sequentially completed induction stroke, compression stroke, expansion stroke and exhaust stroke, piston
Engine is by normal operation.
First oscillating bearing 8 is installed in first link block 5, is equipped with transmission levers 9 in the first oscillating bearing 8,
Opposite first link block 5 of one end energy of the transmission levers 9 is swung, and the other end of transmission levers 9 is hinged with the second connection
Block 10.As shown in Figure 1, the center of the second link block 10 and 9 articulated position of transmission levers is O1Point.Second link block 10, which stretches out, to be passed
The part of dynamic lever 9 is fixedly connected with third link block 11, and hinged 4th link block 12 of the bottom end of third link block 11 is described
One group of plunger pump is equipped on third link block 11 and the 4th link block 12.
Every group of plunger pump includes articulation piece 13, plunger 14 and plunger case 15.One end of the articulation piece 13 respectively with
Ipsilateral third link block 11 or the 4th link block 12 is fixedly connected, and the other end of articulation piece 13 is hinged on plunger 14, described
Plunger 14 is located in plunger case 15 and can slide along.
It is equipped with drive regulating in the side of the transmission levers 9, the drive regulating includes vertically arranged
Hydraulic cylinder 16, hydraulic cylinder 16 are located between two cylinders 2 of side.There are hydraulic push rod 17, hydraulic push rod in the hydraulic cylinder 16
17 bottom is fixedly connected with movable plate 18, and one end of movable plate 18 is installed on transmission levers 9 by second joint bearing 19
Periphery, second joint bearing 19 can be slided along transmission levers 9.The center of second joint bearing 19 and 9 articulated position of transmission levers
For O2Point.The lifting of hydraulic push rod 17 can change position of the second joint bearing 19 on 9 periphery of transmission levers, to adjust biography
The swing pivot of dynamic lever 9, to change transmission ratio.
After starter motor is started by flywheel 7 and crank link mechanism 6 with piston 3, the interior energy that fuel burning generates promotees
Move back and forth piston 3 in cylinder 2, at this point, the piston engine operates normally, first connecting rod 4 drives 5 water of the first link block
It is flat to move back and forth, thus one end reciprocally swinging for the transmission levers 9 for driving it internal by the first link block 5.
As shown in Figure 1, if at this time on movable plate 18 second joint bearing 19 O2The O of point and the second link block 101Point is mutually overlapped
It closes, then the lower end of transmission levers 9 is swung centered on coincidence point, and the second link block 10, third link block 11 and the 4th connect
It connects that block 12 is opposing stationary motionless, at this time etc. is all the neutral gear position of automobile, the driving piston of engine still moves back and forth, but not
Power can be transmitted outward.
As shown in Fig. 2, if at this time on movable plate 18 second joint bearing 19 O2The O of point and the second link block 101Point does not weigh
It closes, then transmission levers 9 are with O2It is swung for fulcrum, the upper end of transmission levers 9 follows 4 reciprocally swinging of first connecting rod, drives and passes
The lower end reciprocally swinging of dynamic lever 9, so that third link block 11 and the 4th link block 12 be driven to drive plunger 14 in plunger case 15
It moves back and forth, and then so that two plunger pumps is replaced outside pump oil, then cooperate existing hydraulic system, two plunger pumps can be replaced
The oil pumped out forms the hydraulic circulation of an one-way flow, thus, the outside output torque of the devices such as hydraulic motor can be driven.
Power can be adjusted in the transfer ratio on transmission levers 9 by position of the second joint bearing 19 on transmission levers 9.
The link mechanisms such as cylinder 2, piston 3, first connecting rod 4 and transmission levers 9 in said mechanism are that former traditional crank passes
20% or so of dynamic output power mechanism weight, can save 80% making material.It is defeated that the overall structure answers class to belong to equiarm
H type engine h out is a kind of reciprocating new concept engine.Due in this structure without in conventional engines crank link mechanism,
Clutch and speed changer, the rotatory inertia of power output shaft can drop subtract 80% more than, be the invention of saving fuel oil.By transmission bar
Bar carries out the transmission of power, gets rid of the interference nocuousness torque of former conventional engines piston linear movement and crank rotary motion.
Preferably, it is hydraulic flexural pivot at the articulated position of second link block 10 and articulation piece 13, can further matches
Close the irregular movement of transmission levers 9 and plunger 14, it is ensured that the stability of power transmission, while hydraulic flexural pivot is also to a certain degree
On increase the service life of its two sides connector.
The technical solution of the utility model is not restricted in the range of embodiment described in the utility model.This is practical new
The technology contents of the not detailed description of type are well-known technique.
