Refer to Fig. 1-Figure 15
Present embodiment provide the first compress the variable motor of when discharge capacity, comprise driving mechanism and at least two group driving mechanisms; Each group driving mechanism comprises cylinder sleeve 101, piston 102 and first connecting rod 103, and piston 102 is located in cylinder sleeve 101, and one end and the piston 102 of first connecting rod 103 are hinged; Driving mechanism comprises bent axle 104 and at least two second connecting rods 105, and one end and the bent axle 104 of each second connecting rod 105 are hinged.
The structure of the driving mechanism of said structure and driving mechanism and motor of the prior art is basically identical.In existing motor, by oil supplying device to cylinder sleeve 101 fuel feeding, and pass through ignition device, oil gas is in cylinder sleeve 101 combustion and drive piston 102 to move, dynamic crankshaft 104 is with to rotate during multiple piston 102 straight reciprocating motion, and in some cylinder sleeves 101 during unburned the return motion of piston 102 be undertaken by the promotion of bent axle 104, the basic functional principle of Here it is available engine.
Each group driving mechanism is all connected with driving mechanism by one group of stroking mechanism; Stroking mechanism comprises drive unit 106, limit point ball-and-socket hinge device 110 is fixed on body, screw mandrel 107, adjusting element 108 and slide block (being configured on body perpendicular in cylinder body slideway) link slide block 109, drive unit 106 is connected with one end of screw mandrel 107 and screw mandrel 107 can be driven to rotate, adjusting element 108 is bolted on screw mandrel 107, the other end of screw mandrel 107 is flexibly connected with slide block link slide block 109, and screw mandrel 107 can rotate by opposing slider link slide block 109;
The other end and the adjusting element 108 of first connecting rod 103 are hinged, and the other end and the slide block link slide block 109 of second connecting rod 105 are hinged.
As shown in the figure, piston 102 moves in cylinder sleeve 101, drives adjusting element 108 to move by first connecting rod 103, and then drives screw mandrel 107 to swing, screw mandrel 107 drives second connecting rod 105 to move by slide block link slide block 109, and then band dynamic crankshaft 104 rotates.
In whole movement process, screw mandrel 107 does oscillating motion, and (110 for being fixed on the spacing ball hinge body on body, and drive unit 106 is arranged at outside body for its fixed support.Therefore, the position of the adjusting element 108 on screw mandrel 107, the closer to the position of limit point ball-and-socket hinge device 110 fixed support, the amplitude of fluctuation of screw mandrel 107 is less; More away from the position of limit point ball-and-socket hinge device 110, the amplitude of fluctuation of leading screw is larger.Furthermore, when adjusting element 108 is positioned at perpendicular to compression ratio during cylinder body center maximum, when the driving adjusting element 108 of drive unit 106 slides on limit point ball-and-socket hinge device 110 direction, the height of adjusting element 108 on screw mandrel 107 diminishes, to making compression ratio diminish,
When adjusting element 108 is positioned at fixed support position, the rotation of bent axle 104 drives second connecting rod 105 to move, and then drives screw mandrel 107 to swing, but adjusting element 108 can not be caused to move up and down, and then makes first connecting rod 103 and piston 102 keep static.
The benefit of this design is, when automobile needs small-power to run, by drive unit 106, the adjusting element 108 of a certain group or a few groups driving mechanism connection can be moved to limit point ball-and-socket hinge device 110 position, some driving mechanisms are closed like this in engine operation process, realize the reduction of discharge capacity. enable motor realize low-power and export, (effect reducing energy consumption when running as used stable road surface on automobile, can be played).

Further, screw mandrel 107 comprises screw section, and the two ends of this screw section are equipped with block piece (limit point ball-and-socket hinge device 110), by this limit point ball-and-socket hinge device 110 can prevent adjusting element 108 and helical thread portion from.Limit point ball-and-socket hinge device 110 for prevent adjusting element 108 and helical thread portion from, play the effect maintaining system stability.
Particularly, link slide block 109 is provided with the pivot hole link slide block 109 be connected with second connecting rod 105 and comprises two pieces of connecting plates be oppositely arranged, between two pieces of connecting plates, be connected with coupling shaft; The end of second connecting rod 105 is provided with axle sleeve.Achieve the connection between second connecting rod 105 and link slide block 109 by such bindiny mechanism, second connecting rod 105 can stably be moved by opposite joints slide block 109.
Preferably, screw mandrel 107 is connected by ball-and-socket hinge device with link slide block 109.Ball-and-socket hinge device can realize the hinged of screw mandrel 107 and link slide block 109, and the relatively rotating of screw mandrel 107 and link slide block 109, and makes stable connection therebetween.
The second that present embodiment provides compresses the variable motor of when discharge capacity, comprises at least two group driving mechanism and driving mechanisms; Driving mechanism comprises cylinder sleeve 101, piston 102 and first connecting rod 103, and piston 102 is located in cylinder sleeve 101, and one end and the piston 102 of first connecting rod 103 are hinged; Driving mechanism comprises d-axis 201, impeller 202 and slide block 203, impeller 202 has at least one and is fixed on d-axis 201, the upper surface of impeller 202 and lower surface all have uniform waveform slideway, this slideway has at least one axially raise a little 204 and at least one axis push away low spot 205; The side margins of each impeller 202 is connected with at least two slide blocks 203; Impeller 202 can be driven to rotate around the axis of d-axis 201 and then drive d-axis 201 to rotate around its axis when slide block 203 does straight reciprocating motion along the axial direction of d-axis 201.
The motor be made up of driving mechanism and the driving mechanism of this structure, specifically runs like this: in its driving mechanism and the first motor, in driving mechanism and available engine, driving mechanism is basically identical; On driving mechanism, d-axis 201 is power output part, and impeller 202 is fixedly connected with d-axis 201 when it rotates and d-axis 201 can be driven to rotate.Impeller 202 is provided with waveform slideway, and slide block 203 is flexibly connected with impeller 202, impeller 202 can be driven when slide block 203 moves up and down to rotate by active forces such as extruding, and then drives d-axis 201 to rotate.
