Description

TECHNICAL FIELD

[0001] The present invention relates to a piston engine using linear stroke output power, and a motor vehicle using the same. BACKGROUND

[0002] As a power output device, the piston engine has been widely used, and there are four-stroke and two-stroke engines, and engines using gasoline, diesel and natural gas. However, all of them use a crank and connecting rod mechanism to output power, and the transmission efficiency of the crank and connecting rod mechanism is reduced due to factors such as reciprocating inertia force, rotational inertia force, dead center position, crank radial force, and piston moving pair friction work. Since the crank angle is different, the force and torque of the piston on the crank, and the transmission efficiency are also different, and thus the output power is large or small. At the dead center position, the transmission efficiency is negative infinity. The engine can still operate continuously because the rotation of the inertia wheel can still drive the crank to rotate. At the instant translation point, i.e., the crank radius r = connecting rod length 1 * sin θ, the transmission efficiency value is < 1 due to the existence of the moving friction pair and the rotating friction pair (θ angle is the angle between the connecting rod and the center symmetry line). At other angle points, the transmission efficiency value is even lower. The existence of the crank radial force also makes the crank need to be designed with higher strength to avoid shortening the service life. The piston moving friction pair has high friction due to the lateral force of the connecting rod. The existence of the inertia flywheel makes the reciprocating inertia force and the rotational inertia force large, which also consumes the work done by the piston, reduces the piston's compression pressure and moving speed. In addition, the internal combustion engine of the automobile also uses the crank and connecting rod mechanism, and there is a need to improve the transmission efficiency. Therefore, the crank and connecting rod engine can still be improved to improve the transmission efficiency, save fuel, and reduce pollution. SUMMARY

[0003] The technical problem to be solved by the present invention is to provide a linear drive engine which can only use the linear motion of the piston to transmit power outward without using the crank and connecting rod transmission, thus eliminating the θ angle: part of the power output outward, eliminating the dead center position, and the transmission efficiency of the piston at each position being equal and closer to 1. The piston no longer generates large friction force from the lateral force of the connecting rod. It can also reduce the inertia force.

[0004] In order to solve the above problems, the application is realized by the following technical scheme: a linear drive engine, comprising: a cylinder sleeve 2 installed in a frame 1, a piston 3 installed in the cylinder sleeve 2, a connecting rod 13 installed on a crank 14 through a crank pin 33, the crank 14 arranged in the middle of a long shaft 15, the long shaft 15 installed in bearing seats on both ends of the frame 1, further comprising a linear stroke component with one end connected in the piston 3 and the other end connected in the connecting rod 13, a clutch transmission component arranged on one side of the linear stroke component, a rotating output component arranged on one end of the clutch transmission component, and an inertia wheel component arranged on one end of the long shaft 15 close to the rotating output component.

[0008] The clutch 26 is a overrunning clutch, which transmits the one-way driving force of the piston working stroke to the long shaft 7 through the engagement of the rack of the straight rod 6 and the gear 16 to drive the long shaft 7 to rotate, and the straight rod 6 no longer drives the long shaft 7 to rotate during the compression and exhaust stroke of the piston.

[0009] The bearing 27 is a rolling bearing.

[0010] A clutch 32 is arranged concentrically between the inertia wheel 21 and the output wheel 23, and functions to combine the output wheel 23 and the inertia wheel 21 when the engine is installed on the vehicle and the brake is applied, so that the engine brake can be used.

[0014] The linear driving engine has the following advantages: the linear stroke component is provided, the angle θ between the engine and the external power output part is eliminated, the work done by the piston 3 during the punching stroke (including the applied thrust) is transmitted to the clutch transmission component in the form of linear thrust instead of crank angle thrust, constant force arm and no dead point position, the lateral force applied by the straight rod 6 to the piston 3 is close to zero, and the kinetic energy of the piston 3 can be transmitted to the outside in a constant manner; the clutch transmission component is provided, the thrust transmitted by the straight rod 6 during the punching stroke is transmitted to the gear 16, the gear 16 transmits the force to the long shaft 7 through the overrunning clutch 26, and the long shaft 7 transmits the force to the gear 17 fixedly arranged on the shaft; the rotating output component is provided, the torque of the gear 17 is transmitted to the output wheel 23; the inertia wheel component is provided in the engine internal power circulation part, which can maintain the continuous and stable operation of the engine, because the inertia wheel only acts on the internal circulation force of the engine, and the external power transmission path does not pass through the crank connecting rod mechanism, so the mass of the inertia wheel can be smaller, the reciprocating inertia force and the rotational inertia force are smaller, and the transmission efficiency of the engine can be improved; the guide component is provided, which can offset the lateral force brought by the gear 16 of the clutch transmission component; the clutch 32 is provided, which can synchronize or desynchronize the rotating speed of the output wheel 23 and the inertia wheel 21, and the clutch 32 is engaged to synchronize the two, which is suitable for engine braking during braking.
