Stroke cam 261 is in contact, and brake switch 703 works.Under two-stroke braking mode, intake rocker 301 and air inlet two-stroke
Cam 252 is in contact, and exhaust master rocker 302 is in contact with exhaust two-stroke cam 262, and brake switch 703 works.Braking is set
The purpose for switching back-moving spring 73K is failed in brake switch 703, i.e., under drive pattern, exhaust brake cam 201 all the time with system
Dynamic switch 703 is in contact, it is to avoid with the rotation and the keying with exhaust valve of the second camshaft 102, occur parts it
Between collision.The stroke cam 251 of air inlet four realizes that inlet valve is opened in intake and exhaust near top dead center, attached in back to back lower dead center
It is near to close；Exhaust four stroke cam 261 realizes that exhaust valve is opened near exhaust bottom dead center, in back to back intake and exhaust top dead centre
Nearby close；Air inlet two-stroke cam 252 realizes that inlet valve is opened and closed near stop in each of the lower；It is vented two-stroke cam 262 real
Existing exhaust valve is opened and closed near stop in each of the lower；Exhaust brake cam 101 realizes that exhaust valve is opened and closed in each near top dead center.This
Invention realizes two-stroke and four-stroke seamless switching using the axial location that axle sleeve is controlled using two changeover modules；One
Brake switch realizes driving and the switching of braking mode.
Changeover module at least includes telescopic pin.The retracted position of pin is controlled by electromagnetism, hydraulic pressure or gas.In Fig. 4, cut
Change traditional plunger matching parts that component is controlled using hydraulic pressure or gas.First changeover module 701 is connected with the first oil circuit 811, and second
Changeover module 702 is connected with the second oil circuit 812, controls the pressure state of the two oil circuits respectively using two control valves.When cutting
When changing component operation, pin stretches out；When changeover module does not work, pin keeps retracted mode.Definition：First 701 pairs of changeover module
The pin answered is pin 1, and the corresponding pin of the second changeover module 702 is pin 2.
The public basic circle section of the cam used according to be switched both of which, it is determined that maximum changeable interval.According to
The contact point of cam and subsequent parts（Cam output point）Circumferential position, the week of the direction of rotation of camshaft and switching mechanism
To position, the impulsive of switching slot is determined., it is necessary to adjust other conditions during any one condition change.Therefore, in reality
, it is necessary to determine public basic circle section, the direction of rotation of camshaft and the cam output point of cam according to actual type in the case of border
Circumferential position, adjust switching slot impulsive and switching mechanism circumferential position.In the embodiment that the present invention is listed, the
One camshaft 101 is rotate counterclockwise, and the second camshaft 102 is turns clockwise, and the circumferential position of changeover module uses two kinds
Different schemes, such as Fig. 9 and Figure 11.In addition, the first and second switching slot can be separated from each other, such as Fig. 9 and Figure 11；By merging
The two, can be integrally combined, such as Figure 10 by the public direction section of the two.
Four-stoke mode to two-stroke mode switch when, the first changeover module 701 works, and pin 1 reaches the first switching slot
In 271, with the rotation of the first camshaft 101, pin 1 promotes axle sleeve 2 to be moved to the left, and drives the cam of intake rocker 301 by entering
The stroke cam 251 of gas four switches to air inlet two-stroke cam 252, drives the cam of exhaust rocker arm 302 by exhaust four stroke cam
261 switch to exhaust two-stroke cam 262.Two-stroke mode to four-stoke mode switch when, the second changeover module 702 works,
Pin 2 is reached in the second switching slot 272, with the rotation of the first camshaft 101, pin 2 promote axle sleeve 2 move right, drive into
The cam of gas rocking arm 301 switches to the stroke cam 251 of air inlet four by air inlet two-stroke cam 252, drives the convex of exhaust rocker arm 302
Wheel switches to exhaust four stroke cam 261 by exhaust two-stroke cam 262.Note：In system schematic, moved towards paper outside
Move to be moved to the left, otherwise to move right.
From above-mentioned, by controlling the state of each changeover module, four-stoke mode and two-stroke mode are realized.Work as switching
Component operation, after corresponding pin is reached in switching slot, switches between pattern and is completed in a circulation, this drives mould to two-stroke
Response quickly is met when switching between formula and four stroke drive patterns and power output is continuously most important.
