Description

Rotary piston engine Technical field:

The present invention relates to an internal combustion engine, and more particularly to a rotary piston engine.

Background technique:

At present, domestic and international practical internal combustion engines mainly include reciprocating piston engines and triangular piston rotary engines (referred to as rotary engines). Reciprocating piston engines are only about 40% inefficient and high in weight G/Ne, low in power Ne/zVh, and sewage. many. The rotor engine has lower efficiency than the reciprocating piston engine G/Ne. However, the seal is not good, the compression ratio cannot be high, so it has not been made into a diesel engine until now, and the output torque is small at the same displacement, and the performance is not as good as that of the reciprocating piston engine. Not universally used. In order to overcome the above shortcomings, many rotary piston engines have been invented, but they are not practical because of the inertial force of the piston walking, stopping, and walking, and the engagement and separation problems of the piston and the main shaft, and the consumption of the variable volume working chamber. Energy is reduced in efficiency and complex in structure.

Summary of the invention:

The rotary wing piston engine (referred to as a rotary wing engine) of the present invention is mainly composed of two sets of pistons, a main shaft and a clutch, a pull-out member and a brake of a clutch puller which are disposed in a sealed cylinder body.

A pair of hollow shafts are connected to the piston hubs of the two groups, and a controllable one-way overrunning clutch is installed in the inner diameter of the hollow shaft. The inner diameter of the clutch is installed in the inner diameter of the clutch. The axis of the hollow shaft and the main shaft of the two pistons are the same line, and the main shaft rotates continuously. The piston shafts are rotated at independent circumferential angles, and the rotation and the spindle are rotated or separated to stop.

When a set of pistons is stopped, the space inside the cylinder is isolated into two or more enclosed spaces. In this space, another set of pistons and the main shaft are engaged at an angle of rotation to work, and the piston group is stopped at the same time as the exhaust gas, compression, work, and exhaust. The rotational inertia force at the time is eliminated by the combustion pressure of the next other piston work.

The above structure makes the piston have no impact force on the cylinder body, good sealing performance, small vibration of the whole machine, high ratio of total volume to displacement, and the structure of the clutch and the brake consisting of walking, stopping and walking is to solve the separation from the main shaft when the piston is stopped. The problem is therefore the ability to manufacture a rotary piston engine with better performance.

First, the working principle of the diesel rotor engine will be explained.

The structure of the diesel rotor engine is the group A piston 3 in the cylinder 1 shown in Fig. 1. The piston hub has wing-shaped A1 and A3 pistons, and the group B piston 4 has wing-shaped B2 and B4 pistons on the piston hub, A, B. The piston sets are placed in the cylinder and can only be rotated within the two pistons. When the other shaft is engaged with the main shaft, the other piston is separated from the main shaft for intermittent rotation.

The one-way overrunning clutch 10 is the outer ring active (piston side) inner ring driven (spindle 2), installed in the piston hub, and the controllable one-way overrunning clutch 42 is the outer ring driven (piston side) inner ring The moving (spindle 2) is installed in the inner diameter of the hollow shaft of the piston, that is, the A and B piston sets are each equipped with a one-way overrunning clutch and a controllable one-way overrunning clutch. Each of the A and B sets of piston hollow shafts is connected with a brake.

Intake stroke a: The starter rotates the spindle 2 and its torque passes through the controllable one-way overrunning clutch on the piston side of group A to rotate the group A piston. At this time, the rear of the A1 piston generates negative pressure suction, and the air passes through the air inlet 5 When the front part of the A1 piston in the cylinder is rotated to the position of the injector 8, the pull-out of the one-way overrunning clutch 42 is controlled to pull the inner and outer rings of the clutch to disengage the group A piston from the main shaft 2, and the group A piston side brake wheel system The piston stops rotating and cannot be reversed. It can only be forwarded to a piston end face arc length and the end of the intake stroke.

Compression stroke b: Group A piston stops while Group B piston side controllable one-way overrunning clutch engages with spindle and Group B piston to rotate B2 piston. B2 piston rear air intake front air compresses to A1 piston rear. This compressed air pushes A1 piston, A1 piston combustion chamber 9 just to the injector position, the pin pin blocks the brake piston of Group A of the brake groove, and stops the A1 piston. At this time, the front part of the B2 piston abuts against the rear of the A1 piston. Compressed into the combustion chamber 9 while the B-group piston side controllable one-way overrunning clutch pulls the clutch inner and outer rings to disengage the B group piston and the main shaft, while the B group piston side brake wheel brakes, the B2 piston cannot reverse At this point, the compressed air pressure and temperature rise in the combustion chamber can ignite the fuel, and the compression stroke is finished. Work stroke c: When the B2 piston compression stroke is finished, the brakes of Group A piston are released. At this time, the pistons of Group A can control the inner and outer rings of the overrunning clutch to rotate. At the same time, the fuel injector 8 sprays fuel, and the fuel combustion works to promote the A1 piston. Rotating, the A3 pistons connected together also rotate, and the front air of the A3 piston compresses the rear intake air, while the one-way overrunning clutch 10 in the A-group piston hub engages the rotating spindle 2 to output power.

Exhaust stroke d: A3 piston front compression stroke end A1 piston rear combustion chamber 9 has started to exhaust the exhaust gas to the exhaust port 6, and the combustion chamber 9 to the front portion of the scavenging port 62 has another blower blows the wind through the scavenging duct. 7 Sweep the residual exhaust gas in the combustion chamber.

Normal engine operation e: A1 piston is connected to the front of the A3 piston and the air is compressed to the rear of the next combustion work piston B2. This air pressure pushes the combustion chamber of the B2 piston to the position of the injector 8 when the A3 piston Close to the rear of the B2 piston, the air is compressed into the combustion chamber, and the compression stroke is finished. At the same time, the injector is injected with fuel, and the fuel is burned. The B2 piston performs work rotation. At this time, the inner and outer rings of the one-way overrunning clutch 10 in the piston side of the B group are engaged with the rotating main shaft. 2 output power, B2 piston rear work and front exhaust, the front of the B4 piston is compressed to compress the rear air to prepare for the next cycle, that is, normal operation after engine start, intake, compression , work and exhaust are carried out at the same time, so no flywheel is needed. At this time, the combustion pressure at the rear of the B2 piston stops the rotation of the A3 piston at the end of the compression stroke, and the rotational inertia force of the A-group piston is eliminated. The rotation direction of the A-group piston and the B-group piston is the same, so the rotation inertia of the A-group piston The energy is added to the gas on the back of the B2 piston to improve efficiency.

In summary, the cycle process of the rotor engine intake, compression, work, exhaust, and four strokes is reasonable. DRAWINGS

There is more than one injector 8 on the cylinder. The fuel is pumped by the high-pressure oil pump into the injector to inject fuel. The injection time is from the position of the piston combustion chamber 9 to the injector and the inside and outside of the controllable one-way overrunning clutch. The ring contact or disengagement time is set, and if the position of the combustion chamber 9 to the injector is replaced by a magnetic clutch, the magnetic clutch is turned on or off to set.

There is a peripheral cooling water inlet on the cylinder block. 14. The cooling water is pumped from the radiator tank through the water pump into the cooling water passage of the cylinder body body. 12 The cylinder body is cooled and then returned to the water tank through the cooling water outlet.

Bolts 41 for mounting the cylinder head evenly distributed on the end faces on both sides of the cylinder block.

A and B sets of piston hubs have a ring groove 33 for the gas seal ring and the oil seal ring on the side, and a large-diameter seal ring groove on one side is a gas seal ring groove, and the outer diameter of the ring groove is equidistant More than one horn-shaped protrusion groove, a circular gas seal ring with a horn-shaped protrusion on the inner side of the gas seal ring groove, a circular seal ring on the inner side of the seal ring, the seal ring joint and the seal with the protrusion The joint of the ring is staggered, and the small-diameter seal ring groove on the other side is an oil seal ring groove. The groove is communicated with the cooling oil outlet through the oil hole. The oil seal ring is composed of more than one inner ring and outer ring. The joints of the ring are staggered and installed in the ring groove, and the bottom of the gas and oil seal ring has a spring. The gas seal ring and the oil seal ring prevent the gas in the cylinder from leaking between the two sets of piston hubs, and the hollow shaft hub has A sealing ring groove 25 of a horn-shaped protrusion, a sealing ring having a horn-shaped protrusion is disposed on the inner and outer sides of the hollow shaft hub sealing ring groove, and a circular sealing ring is further disposed on the inner side of the sealing ring.

The rotary wing engine piston is composed of two sets of pistons A and B. Each set of piston hub has two or more pistons 26 fixedly connected on the outer diameter thereof. The A and B piston sets are mutually placed in the cylinder body, and the piston hollow shaft axis and The axis of the main shaft 2 is the same line, and the piston rotates on the central circumference of the axis. Each of the pistons has a combustion chamber 9, an inner chamber 27, and two or more gas seal groove grooves 36 and one communicating with each other on the peripheral and both end faces. The oil seal groove 35 of the above oil seal groove is supplied by the oil hole 34 which is interconnected by the inner cavity 27, and the air seal groove and the oil seal groove are respectively placed with two or more rectangular gas seals of two sides which are not equal in length. The sheet and the oil sealing sheet 37, and the same gas and oil sealing sheet, are stacked in a gas and oil sealing groove, and the gas sealing sheet and the oil sealing sheet are used to prevent the piston and the cylinder, Air leaks in the cylinder head clearance. ,

The inner diameters of the piston hubs of the two groups A and B are respectively installed with the outer ring active (piston side) inner ring driven (spindle 2) one-way overrunning clutch 10, and the inner ring of the clutch is fixed with the key to install the main shaft 2, one-way beyond The clutch is used for torque output when the piston is working. The two sets of piston hubs are connected to the hollow shaft 32 outside, and the piston hollow shaft 32 is mounted in the inner diameter of the sliding bearing 40 on the inner diameter of the cylinder head, and a controllable one-way overrunning clutch 42 is respectively mounted in the inner diameter of the hollow shaft, and two or more concave grooves are symmetrically formed on the outer diameter of the clutch and the inner diameter of the hollow shaft 32. The cooling oil flows out of the tank, and the controllable one-way overrunning clutch 42 is an outer ring driven (piston side) inner ring active (spindle 2), and the inner ring is mounted on the main shaft by a key, and the clutch 42 is coupled with the main shaft 2 or The separation drives the piston shaft 32 to rotate to form an intermittent movement of the piston to go, stop, and walk.

The above-mentioned controllable one-way overrunning clutch and one-way overrunning clutch can be replaced by a magnetic clutch. At this time, one piston group uses only one magnetic clutch, and the magnetic clutch is larger than the one-way overrunning clutch, so the piston hub or the piston hollow shaft is installed. When the corresponding hub or hollow shaft is made larger, a switch circuit and a power supply system synchronized with the rotation of the piston are installed, and the contacts of the switch circuit are mounted on the lower end of the pin 49, and the piston position sensor and the electronic switch circuit can also be used instead of the contacts. Switch circuit.

The pulling of the pulling claw 43 of the controllable one-way overrunning clutch 42 is that the shaft gear 55 rotates to rotate the driven driven gear 54 together, the driven gear shaft is connected with the cam shaft 51, and the cam 50 mounted on the cam shaft rotates to push the column The upper and lower flat bottom followers of the pin 49 are moved, and the pin is mounted on the cam bearing support frame 52. The support frame is mounted on the inner diameter wall of the cylinder head, and the lower end of the stud leg member 65 is curved in the sliding disc 45. The sliding disc 45 is pushed in the hole 64. The sliding disc is filled with balls on both sides of the inner diameter of the disc, so the sliding disc is a power arm that can move laterally on the shaft and rotate circumferentially, and the sliding disc pushes the lever 44 on the clutch puller. The lever is mounted on the side of the clutch at a small angle. At this time, the rotation of the resistance arm of the lever connected to the claw causes the angle of rotation of the clutch puller 43 to separate the outer ring of the controllable one-way overrunning clutch from the inner ring, that is, The separation between the piston shaft and the main shaft is realized, and the rotation angle of the claw is adjusted by the length of both sides of the lever. The lever 44 has a return spring, and the function of the spring is to return the lever when the sliding disc has no thrust. In the original position, the main shaft and the piston shaft are engaged.

The head of the pin 49 is a sloped surface, and the upper part and the lower part each have a flat bottom follower, and the middle part of the pin has a swing spring, and the function of the spring is that the cam pushes the follower to make the pin head enter the brake groove, or the brake is released. After the groove is maintained as it is, the lower leg of the pin is pushed by the sliding leg and the head of the pin is inserted into the braking groove 48 of the brake wheel 46 to brake the piston. The front part of the braking groove is inclined and the pin head is aligned. The bevel, the brake wheel is bolted through the bolt hole 47 in the threaded hole 39 of the end face of the hollow shaft of the piston. When the brake wheel is braked, the piston cannot be reversed, but the forward rotation can be turned to a piston end face distance and then blocked. Because the length of the brake groove is so long, the role is that the piston does not reverse at the end of the compression stroke and the combustion chamber 9 can move to the position of the combustion work stroke. After the start of combustion, the pin is released from the brake groove to release the brake. Rotation, the arc length 1 of the brake groove is equal to the arc length of the piston end face corresponding to the brake groove I plus the thickness of the head of the pin after the head is inclined, that is, 1 = I + a, the piston of group B is to be braked when the piston of group A rotates The state is also the brake wheel on the hollow shaft of the pistons on both sides. Cropping system The movement and release actions are adjusted by the gear ratio of the shaft gear 55 and the driven gear 54 and each cycle of the cam, that is, δ. + δ _s + δ + δ The motion angle δ of the derivation in 2 2 π. Adjust the setting with the angle of the far angle of repose δ _s . The movement of the cam, the pin and the sliding disc should match the piston stroke. The rotation start time of the piston is the last injection of the injector and the next injection. Adjust the length of the previous injection injection time.

The follower of the cam mechanism is a flat bottom member. The structure in which the cam has a follower contact in the upper and lower positions is a synchronous movement of the pin and the cam. This structure has no structure compared with a general follower and a return spring. Hysteresis.

The magnetic clutch on time is 0. 3 or so, the magnetic clutch on time is 0. 3, the magnetic clutch on time is 0. 3, the magnetic clutch on time is 0. 3 /s, so the engine is low speed. If you want to increase the engine speed, the clutch or clutch engagement time with faster engagement and disengagement time should be advanced, that is, the clutch puller should be pulled ahead of time. The other method is engine start. The controllable one-way overrunning clutch 42 is not used when the rear rotation speed reaches a certain value. The specific method is to fix the mounting sleeve 66 on the main shaft 2, and the fulcrum of the acute angle lever is movably mounted on the hole on the sleeve, and the power arm of the lever is used. Connected to the heavy ball, the other end of the power arm is connected to the spring. The other end of the spring is connected to the sleeve. The resistance arm of the lever is shorter than the power arm, and the power arm is at the center of the fulcrum and forms an acute angle with the resistance arm. One end of the wire rope is connected, and the other end of the wire rope is connected to the power arm of the lever 44 on the claw, and the operation mode is the main shaft. When the certain speed is reached, the weight of the ball generates centrifugal force against the pulling force of the spring to pull the lever of the lever to the circumferential direction. At this time, the wire rope connected to the resistance arm pulls the lever 44, and the lever pulls the clutch 43 of the clutch 42 to make the piston shaft and the spindle Separate, the engine piston runs automatically, so the engine speed is not limited by the clutch 42, and the speed can reach a high speed. The cylinder head 15 is the same two pieces of bolts evenly distributed on both end faces of the cylinder block. 41 bolts corresponding to the bolt holes 23 are mounted on both sides of the cylinder head 15 and then tightened with a nut.

The intake port and the exhaust port have no valves, and are normally open.

There is also a cylinder head cooling water inlet 19, and the cooling water passes through the cooling water passage 21 to cool the cylinder head and then flows out through the cooling water outlet 20.

The driving gear is engaged with the transmission chain to rotate the high-pressure fuel pump, the water pump, the oil pump, the generator, the blower and the like. The required machines are powered. These machine parts are installed at the appropriate part of the front of the engine. The front end of the main shaft 2 is equipped with a fan 58. The front of the fan has a radiator tank. The cooling water of the tank is pumped into the pipeline and into the water inlet. After cooling the cylinder block and the cylinder head, the water outlet and the return pipe are connected to the water tank to form a cooling water circulation to control the engine body temperature.

Oil cooling and oil lubrication are the oil in the oil sump in the base. After the filter, the oil pump is used to pump the oil pipe to the right angle rotary wide 28 into the piston hollow shaft oil hole 29 and the cooling oil inlet 30 into the piston inner chamber 27 to cool the piston And the piston oil seal ring groove and the piston hub oil seal ring groove are supplied with oil and flow out through the outlet 31 to the two or more concave gaps between the controllable one-way overrunning clutch 42 and the piston hollow shaft 32 while the clutch is slid The disc, the cam, the gear, etc. are lubricated, and the oil entering the oil hole 29 is lubricated through the small hole into the sliding bearing 40. The oil cools the piston and lubricates the parts, and then returns from the oil outlet 56 to the oil sump to complete the circulation.
