Abstract

The utility model relates to a rotating board engine, belonging to the technical field of an automobile engine. A cylinder shape cylinder body is adopted by the rotating board engine, and sealing cylinder covers are arranged on two side surfaces of the rotating board engine. A combustion chamber and an exhaust plunger are arranged on the wall of the cylinder shape cylinder body. An arc shaft operated air blocking plate is arranged on the inner wall of the cylinder shape cylinder body along position pliers. The arc shaft operated air blocking plate not only can seal the opening of the combustion chamber, but also can rotate along a fixing shaft, and the arc shaft operated air blocking plate and a crank shaft rotating plate fixed on a main shaft form a cylinder cavity. The rotating board engine does not use a crank shaft or a crankcase. The rotating board engine has small volume, light weight, simple structure, and easy manufacture and maintenance, and generates higher effective power.

Description

Rotating board engine

The utility model relates to a kind of rotary board type engine, belongs to technical field of automobile engine.

In technique known, motor car engine adopts reciprocating-piston engine or wankel engine more.The former need use bent axle and crankcase at transmission, and volume is bigger, and the power that produces is less, complex structure, processing maintenance difficult.The latter can only have 1/3rd space to do the firing chamber in a cylinder of motor, and each work done can only be rotated 120 °, and the big and machining of power loss requires high.

The purpose of this utility model is to overcome the deficiency that above-mentioned motor exists, and provides that a kind of volume is little without bent axle, crankcase, and is in light weight, simple in structure, the rotary board type engine that useful horsepower is higher.

Below in conjunction with accompanying drawing the utility model is introduced.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the A--A cut-away view of Fig. 1;

Fig. 3 is the snap ring structural representation on the sealing cylinder cap of the present utility model;

Fig. 4 is a worm's eye view of the present utility model;

Fig. 5 is a plan view of the present utility model.

Among the figure, 1 is main shaft, and 2 is the spark plug lobe plate, and 3 is the injection cam plate, 4 are extension spring, and 5 are the oil spout support plate, and 6 are the exhaust support plate, and 7 is spring, 8 is the snap ring closed chamber, and 9 is snap ring, and 10 is the exhaust cam plate, 11 is spark plug, and 12 is engine cylinder cover, and 13 is engine cylinder-body, 14 for driving a rotor plate, and 15 for driving anti-aeration plate, and 16 is the firing chamber, 17 is injection plunger, and 18 is exhaust piston, and 19 is exhaust port.

Rotary board type engine comprises cylinder body 13, cylinder cap 12, main shaft 1, combustion chamber 16, injection cam plate 3, oil spout support plate 5, exhaust cam plate 10, exhaust support plate 6, be characterized in that this engine cylinder-body 13 adopts circle tube cylinder, there is sealing cylinder cap 12 two sides, which is provided with snap ring 9 structures of energy automatic telescopic. Be provided with at the wall of cylinder body 13 equally distributed, and with cylinder in the even number combustion chamber 16 and the exhaust piston 18 that communicate. At the inwall of this engine cylinder-body 13 along the place, and with the intersection area, combustion chamber, pincers are equipped with the moving chock flap 15 of arc shaft, the moving chock flap 15 of arc shaft can closed chamber's mouth, can rotate along fixed axis O point again, with bent axle rotor plate 14 formation cylinder chambers (being working chamber) fixing on the main shaft 1. What accompanying drawing 2 of the present utility model provided is the rotary board type engine of two working chambers. This engine can according to actual needs, design a plurality of working chambers (but must be even number), a piston cylinder of each similar reciprocating-piston engine in chamber. The quantity of snap ring 9 structures of automatic telescopic also should conform to real work chamber quantity on this engine sealing cylinder cap. Snap ring 9 structures of automatic telescopic are to adopt the spindle hole edge on sealing cylinder cap 12 and be positioned at the extreme position that the moving chock flap 15 of axle rotates, and the snap ring 9 with spring 7 controls is installed, and for guaranteeing sealing herein, are provided with the snap ring closed chamber 8 of evagination. Other parts of the present utility model, such as spark plug 11, spark plug lobe plate 2, injection cam plate 3, oil spout support plate 5, exhaust support plate 6, the auxiliary components such as exhaust cam plate 10 and fuel injector be identical with existing common engine all, so do not set forth.

When rotary board type engine has just started, the moving chock flap 15 of arc shaft blocks burner port, injection plunger 17 this moment vibration upwards, the 16 interior oil spouts to the combustion chamber, spark plug lobe plate 2 pluggeds, spark plug 11 igniting make combustion chamber 16 interior generation gases at high pressure, promote the moving chock flap 15 of arc shaft and rotate as the center of circle take the O point. When forwarding certain angle to, arc surface and main shaft 1 arc surface of the end points of the moving chock flap 15 of axle match, and form air-tight state. Forcing gases at high pressure to go to promote to drive axle rotor plate 14 rotates counterclockwise. Exhaust piston vibration exhaust this moment, all air pressure leaks through steam vent 19. Go to the edge that another piece axle moves chock flap 15 when driving the axle rotor plate, another injection plunger 17 vibration oil spouts, its plug ignition, produce gases at high pressure in its combustion chamber, promoting the moving chock flap 15 of its axle rotates, again form air-tight state, make gases at high pressure go to promote to drive axle rotor plate 14 and be rotated further, with this reciprocation cycle. The snap ring 9 of the automatic telescopic that is provided with at the two side seal cylinder caps 12 of this engine cylinder-body is the projection shape, and a side is with the inclined-plane, when the moving chock flap 15 of axle goes to extreme position (coincide with main shaft 1 form air-tight state), collides with snap ring 9 and to be obstructed. But when driving axle rotor plate 14 and go to snap ring 9 place, the place, inclined-plane that promotes snap ring 9 outwards moves snap ring 9 Compress Springs 7, and driving axle rotor plate 14 can be rotated further. Snap ring 9 automatically resets by spring 7, realizes automatic telescopic.

The utility model volume is little, and is in light weight, and structure is simpler, and the useful horsepower of generation is higher, and is easy to processing, maintenance.
