The working principle of the utility model is described as follows:

The inclination for needing to illustrate to drive groove in the utility model is somebody's turn to do for being axially moved the axial line of component Drive " the place face " of groove to get over the vertical plane close to axial line, then its gradient is bigger, and it is on the contrary then its gradient is smaller, it is gentler.

In actual work, the axial-rotation driving mechanism in the utility model tilts closed loop by being axially moved above component The driving trenched side-wall of design pushes the rolling element movement of rotary motion component, enables rotary motion component continuous rotation, It is moved to which the linear motion of piston to be converted to the continuous rotation of output revolving shaft.During being somebody's turn to do, the power of piston output is Direction is changed by axial-rotation driving mechanism, and is absolutely not decomposed, seldom a part of frictional force, the overwhelming majority are removed Power is delivered to output revolving shaft output.And piston acting starting point and end dead point area very little, most of energy it is sharp With.Therefore, from the transfer efficiency of its energy for the structure of itself much higher than conventional crankshaft-linking rod drive mechanism.

Output revolving shaft passes through timing gears while rotating and the mating band moving cam axis of cam shaft gear rotates, cam Axis one end is equipped with the edge cam acted on rocker arm, and the cam curve on edge cam is to change by valve lift curve and design , corresponding cam groove also coincide with the curve, therefore is also just being able to drive rocker arm just when ball rolls in cam groove Normally opened conjunction valve, then being capable of valve gap adjustment by the valve lash adjusting screw on rocker arm.

Secondly, the existing four-stroke engine using crankshaft-linking rod drive mechanism, itself structure determines its four rows Journey operating angle is restricted to 180 degree, and therefore, piston intake time and working application time are all fixed, but from four cycle engines We can analyze out the cylinder of same discharge capacity in four impulse strokes to four impulse strokes of machine, if entered more in cylinder body More oil gas or working application time lengthening can make engine power bigger, and people can only lead in existing crankshaft-link rod engine The mode for crossing the inlet valve of open time delay shutdown in advance allows more oil gas to enter cylinder body as far as possible, but the utility model can be by changing Become the driving groove path being axially moved on component to design to increase charging stage corresponding rotational angle (> 180 degree), it is ensured that Extend piston downgoing time when air inlet under the premise of engine speed is constant, to enter more oil gas in cylinder, improves hair Motivation power.Certainly we can also be by driving the optimization design of the side wall profile line of groove (it is initial to improve side wall profile line Gradient) so that piston is accelerated downstream rate at downlink initial stage, thus make to increase the negative pressure in cylinder in same downgoing time faster, from And enter more oil gas, further increase engine power.

In conjunction with shown in Fig. 1 ~ Fig. 3, it is integrally formed with piston fixed link 10 in axial movement component 5 described in the present embodiment, The piston fixed link 10 passes through case lid 2 and is connected with piston 4；And guiding mechanism described in the present embodiment includes four and transports along piston 4 Line direction guide post 11 disposed in parallel, these guide posts 11 are centrosymmetric setting about the circle center for being axially moved component 5.And And every 11 one end of guide post is fixed with case lid 2, and the other end is then fixed with a guide pillar support 12, cooperates on each guide post 11 It is arranged there are two sliding guide sleeve 13, these sliding guide sleeves 13, which are integrally provided on, to be axially moved on component 5.And 1 He of cabinet It is equipped with the bearing 14 being placed on output revolving shaft 7 in guide pillar support 12, and is respectively equipped on output revolving shaft 7 and above-mentioned two side bearing 14 shaft shoulder portions to offset are to limit the axial movement of rotary motion component 6.

Rolling element 9 described in the present embodiment is idler wheel, and specifically as shown in connection with fig. 2, the pivotal axis of the idler wheel is perpendicular to driving The floor design of groove 8, therefore the rolling surface of idler wheel contacts rolling with the two side walls of driving groove 8.

As shown in figure 3, the part of not set driving groove 8 is hollow out knot in axial movement component 5 described in the present embodiment Structure is to mitigate weight.

As shown in connection with fig. 1, the master section in the present embodiment is mounted on 7 end of output revolving shaft on cabinet 1, the generator Including the stator support 27 on the rotor 26 and static housing 1 that are fixed on output revolving shaft 7, it is fixed with and turns on stator support 27 The stator 28 of 26 cooperation of son.Rotor 26 is by the flywheel 29 being fixed on output revolving shaft 7 and the permanent-magnet magnetic being pasted on the inside of flywheel 29 Steel 30 is constituted, and stator 28 is located at 26 inside of rotor, and the cooling fan positioned at 29 outside of flywheel is further fixed on output revolving shaft 7 31, it further include cabinet wind scooper 32, cabinet 1 is fixed in the cabinet wind scooper 32, and hair is surrounded in the connection of 32 one end of cabinet wind scooper The generator wind scooper 33 of motor, and the cylinder head wind scooper 34 of cylinder head 3 is surrounded in the connection of 32 other end of cabinet wind scooper.

The considerations of for stress balance between axial movement component 5 and rotary motion component 6 and stability, the present embodiment Described in driving groove 8 use identical two, and this two driving grooves 8 be axially moved component 5 circumference on about Circle center is spaced apart in angularly (180 degree), and there are two crosspoints for two driving groove 8 tools.For clear explanation and take off The shape and the positional relationship between rolling element 9 for showing driving groove 8, by two driving grooves 8, circumferentially shape is unfolded in face for we At plane distribution schematic diagram as shown in Figure 5.And the curve after driving groove 8 to be unfolded for wherein one is named as first groove Curve 801, the initial position of rolling element 9 therein are named as the first rolling element initial position 901；And another driving ditch Curve after slot 8 is unfolded is named as second groove curve 802, and the initial position of rolling element 9 therein is named as the second rolling Body initial position 902.

And it may be noted that two driving grooves 8 and its interior rolling element 9 have displacement in the axial direction in the present embodiment, It is staggered, design in this way has its purpose.Because if two driving groove 8 interval 180 degrees design but in the axial direction without position It moves, then since the initial position of the rolling element 9 in driving groove 8 has to be perfectly the same, therefore in practical application, it is possible that Rolling element 9 in each driving groove 8 at a time simultaneously by crosspoint the case where, as shown in Figure 6.At this point, 9 phase of rolling element It being detached from when in same driving groove 8, rotary motion component 6 generates breakpoint without stress, so as to cause driving, although influencing less, The run stability that still will cause entire axial-rotation driving mechanism, the driving groove 8 to avoid such case, therefore in this case Optimization design as shown in Figure 5 is used with the position of rolling element 9.It is equivalent to compared to Fig. 6, Fig. 5 the first groove in Fig. 6 is bent The translation certain distance downwards of line 801, second groove curve 802 is constant, so that the first rolling element initial position 901 and the Two rolling element initial positions 902 are staggered in the axial direction, namely make two driving grooves 8 in the axial direction for being axially moved component 5 It is upper that there is displacement, and two rolling elements 9 are staggered in the axial direction, to avoid all rolling elements 9 while appear in friendship On crunode.

Below we further combined with Fig. 7 and Fig. 8, that the present invention will be further described is as follows, Fig. 7 is the utility model Relational graph between middle 7 rotational angle of output revolving shaft and 4 path curves of piston, abscissa are that output revolving shaft respectively corresponds four Stroke Engine air inlet, compression, acting and the rotational angle for being vented four-stage, also referred to as operating angle, curve are then pistons 4 Motion profile, the shape with the driving groove 8 on 5 surface of moving link axial in this case is corresponding associated.And Fig. 8 is then Relational graph in conventional four-stroke engine between crank rotation angle and its piston trajectory curve.

It is known that the existing four-stroke engine using crankshaft-linking rod drive mechanism, itself structure determine its into Gas, compression, acting and the four-stage of exhaust stroke crankshaft operating angle be restricted to 180 degree, as shown in Figure 8.Therefore, 4 inlet period of piston and working application time are all fixed, but we can analyze out from four impulse strokes of four-stroke engine The cylinder of same discharge capacity is in four impulse strokes, if entering more oil gas or working application time lengthening in cylinder body can make to send out Motivation is more powerful, and people can only be by way of shifting to an earlier date open time delay and turning off inlet valve in existing crankshaft-link rod engine More oil gas are allowed to enter cylinder body as far as possible, but the utility model passes through the path design for the driving groove 8 being axially moved on component 5 Charging stage corresponding rotational angle (> 180 degree) can be increased, as shown in Figure 7, it is ensured that under the premise of engine speed is constant Extend 4 downgoing time of piston when air inlet, to enter more oil gas in cylinder, improves engine power, and then improve power generation Efficiency.

Meanwhile for four-stroke engine, in four impulse strokes of its piston 4,4 working stroke of piston is also wished Power caused by detonation is hoped there are more time effects on piston 4 to allow more power to pass to output revolving shaft 7, this is practical The corresponding driving groove 8 of 5 working stroke of lucky piston driving groove 8 corresponding with suction stroke is same section in novel, mutually It is overlapped, therefore the rotational angle of suction stroke increase (> 180 degree) similarly makes the rotational angle of working stroke increase (> 180 Degree), it is shown in Figure 7, there is the more time to act on output revolving shaft 7 to allow and fire power, to improve the utilization rate of fuel oil With the Operating ettectiveness of engine, and then improve generating efficiency.It can be seen that the design of the utility model is by extending corresponding piston 8 path length of driving groove of 4 air inlets and power phase, not only increases the power of same displacement engine, also improves and start The efficiency of machine, while also move up the speed of engine best torque point, engine best torque revolving speed is improved, is further mentioned High engine power.

And rolling element 9 and the two of same section of driving groove 8 when in the utility model due to 4 air inlet of piston and power phase Side wall contacts rolling respectively, and we are further by the difference of the two sidewalls profile wire shaped design of this section driving groove 8, and At the beginning of the initial slope of the side wall profile line of corresponding 4 charging stage of piston is greater than the side wall profile line of corresponding 4 power phase of piston Beginning gradient, so that the downstream rate at 4 downlink initial stage of piston is accelerated, as shown in Figure 7 (in same operating angle, the charging stage 4 running track gradient of initial stage piston is greater than power phase, it means that its speed is accelerated) so that in same downgoing time The negative pressure increased in cylinder faster enters more oil gas, further increases engine power, and then promote generator efficiency.

Embodiment 2: in conjunction with shown in Fig. 9 ~ 12, the overall structure of the utility model another kind specific embodiment is the same as embodiment 1 It is essentially identical, and distinctive points are: the design of the axial movement component 5 in axially driving rotating mechanism is on the one hand changed, it will Two of its surface driving grooves 8 relationship is from the circumferencial direction interval 180 degree in embodiment 1 and cross-over design has been changed to along axis It is distributed and does not intersect to the axial direction of moving link 5, i.e., without crosspoint between two driving grooves 8, but two driving grooves 8 remain unchanged Relative to the circle center's interval 180 degree for being axially moved component 5.11 quantity of guide post is still four simultaneously, and still about axis It is centrosymmetric setting to the circle center of moving link 5, the corresponding sliding guide sleeve 13 being axially moved in component 5 is also four It is a.Rolling element 9 on rotary motion component 6 then corresponds to two driving groove 8 redistributions, and necessarily is in two driving grooves Same position in 8.Equally we by two drive grooves 8 circumferentially face are unfolded to be formed plane distribution as shown in figure 11 and are illustrated Figure, first groove curve 801 and second groove curve after can be clearly seen that two driving corresponding expansion of groove 8 802 without crosspoint, and initial position 901,902 of corresponding two rolling elements 9 therein are same in respective groove curve The case where one position, design passes through crosspoint simultaneously without having to worry about rolling element 9 in this way, occurs.

On the other hand the present embodiment has also carried out small improvement for driving mechanism for rocker arm, eliminate convex in embodiment 1 The design of groove 21, ball 22 and ball slider 24 is taken turns, specifically combines shown in Figure 12, acts on end in the present embodiment on rocker arm 16 One end of face cam 20 is equipped with the rocker-arm roller 35 contacted with the surface of edge cam 20, and is fixed on 16 other end of rocker arm Valve lash adjusting screw 23, and offseted by the valve lash adjusting screw 23 with the valve 15.

Remaining assembling structure of the present embodiment is with embodiment 1, and working principle and implementation result are also referring to embodiment 1.

We carry out comparison with the axial-rotation driving machine in the utility model under the premise of discharge capacity in conjunction with Figure 13 ~ Figure 16 below The acting situation of crankshaft-linking rod drive mechanism in structure and conventional engine.

Figure 13 and Figure 14 is respectively with crankshaft-linking rod drive mechanism work stress conventional under the premise of displacement engine Mechanical model schematic diagram and the utility model in axial-rotation driving mechanism work stress mechanical model schematic diagram. P in Figure 13 and Figure 14 represents the power of piston output, and F then represents the direction of rotation driving of two mechanical model output ends Power.Wherein the F in Figure 13 is the component that P is acted on crankshaft, and the F in Figure 14 is then that the rubbed power of P is lost and converts The power on output revolving shaft is acted on behind direction.

It is (equal when the angle of engine charge or acting is identical that two kinds of mechanical models of Figure 13 and 14 are shown in conjunction with Figure 15 For 180 degree), output end direction of rotation driving force compares figure with the change curve of angle；Abscissa T indicates air inlet or acting in figure The variation of angle in stroke.A curve represents the output end direction of rotation driving force of conventional crankshaft-linking rod drive mechanism mechanical model With the change curve of angle, and B curve then represents the output end rotation side of the axial-rotation driving mechanism mechanical model in this case To driving force with the change curve of angle.Ordinate F then indicates the big of the output end direction of rotation driving force of two kinds of mechanical models Small, wherein Fmax1 is the maximum value in the F change procedure of conventional crankshaft-linking rod drive mechanism mechanical model, and Fmax2 is this case Axial-rotation driving mechanism mechanical model F change procedure in maximum value.The F affirmative of two kinds of mechanical models as we know from the figure Respectively less than P, and Fmax2 > Fmax1.Simultaneously it will be apparent that under each angle the F of conventional crankshaft-link rod driving mechanism mechanical model it is steady Qualitative and retentivity is also all not so good as this case.Curve can be characterized as corresponding mechanical model to the graphics area that abscissa surrounds and rotate (in the case that radius of turn is equal, abscissa is equally represented by the drive of direction of rotation to the acting size of direction driving force The distance S that power is passed by), it is upper from figure it is clear that curve B total acting is higher than curve in identical working stroke A。

Figure 16 be two kinds of mechanical models of Figure 13 and 14 in engine charge or the angle difference of acting (conventional engine according to Old 180 degree, and our engine is then greater than 180 degree), output end direction of rotation driving force compares with the change curve of angle Figure.The same with Figure 15, abscissa T, which remains unchanged, in figure indicates the variation of angle in air inlet or working stroke.A curve represents conventional crankshaft The output end direction of rotation driving force of jointed gear unit mechanical model is with the change curve of angle, and B curve then represents this case In axial-rotation driving mechanism mechanical model output end direction of rotation driving force with angle change curve.Ordinate F is then Indicate the size of the output end direction of rotation driving force of two kinds of mechanical models, wherein Fmax1 is conventional crankshaft-linking rod drive mechanism Maximum value in the F change procedure of mechanical model, and Fmax2 is the F variation of the axial-rotation driving mechanism mechanical model of this case Maximum value in the process.The F of two kinds of mechanical models is respectively less than P, and Fmax2 > Fmax1 certainly as we know from the figure.It is very aobvious simultaneously So, the stability of the F of conventional crankshaft-link rod driving mechanism mechanical model and retentivity are also all not so good as this case under each angle.Curve with The graphics area that abscissa surrounds can be characterized as the acting size (rotation half of corresponding mechanical model direction of rotation driving force In the case that diameter is equal, abscissa is equally represented by the distance S that the driving force of direction of rotation is passed by), it can understand from figure Find out, since the acting angle of this case increases, the driving force time acted on output revolving shaft is longer, and work distance is also longer, Therefore curve B total acting is much higher than curve A.

Actually two curves A and B can also regard the energy conversion efficiency curve of corresponding respective mechanical model as, from figure It is shown in 15 and Figure 16 and in conjunction with the energy conversion efficiency that analysis above can specify the axial-rotation driving mechanism in this case Much higher than conventional crankshaft-linking rod drive mechanism, the power and efficiency of corresponding engine are also higher.

Certainly the above embodiments are only for explaining the technical ideas and features of the present invention, and its object is to allow be familiar with this The people of technology can understand the content of the utility model and implement accordingly, and the protection model of the utility model can not be limited with this It encloses.Any modifications made in accordance with the spirit of the main technical solutions of the utility model should all cover the guarantor in the utility model Within the scope of shield.
