Description

New high-efficiency mover engine

technical field

The utility model relates to the field of engines.

technical background

The traditional reciprocating engine has a history of more than one hundred years, and has been perfected day by day through continuous improvement and improvement. However, the inertial force and inertial torque caused by the reciprocating motion of the piston cannot be completely balanced, especially as the engine continues to develop in the direction of high speed, these unbalanced forces and moments increase sharply, and the inertial force acting on the engine bearings The load increases significantly and causes an increase in vibration and noise.

At present, the mainstream engine of cars on the market is an inline four-cylinder engine. In this engine, when the two pistons move to the highest point (at this time, the connection between the two pistons and the crankshaft is also at the highest point of the entire trajectory), the pistons of the other two cylinders just move to the lowest point (these two pistons The connection between the bottom and the crankshaft is also at the lowest point of the entire trajectory), at this time, the two pistons at the highest point are stressed vertically downward, and the support force at the connection point of the crankshaft is upward, and the force is offset here, resulting in energy loss , in the same way, the two pistons at the lowest point will have the same energy loss, which greatly reduces the working efficiency of the engine. At the same time, the processing technology of the crankshaft and other kinematic mechanisms of the reciprocating engine is complicated, and the processing cost is relatively high.

Since the 1950s, some new rotary piston engines have been trial-produced abroad, mainly the triangular rotor engine (hereinafter referred to as the rotary engine) designed by Sid Wankel. It uses triangular rotor rotary motion to control compression and discharge, as opposed to the linear motion of traditional piston reciprocating engines.

The main parts of the rotary engine include: rotor, cylinder block, front and rear end covers, main shaft, phase gear, sealing plate, etc. The rotor rotates in the cylinder and divides the cylinder into three different working chambers, each of which completes different working cycles. The expansion pressure generated by the combustion chamber pushes the rotor, and the rotor drives the main shaft to rotate and perform work. The same as the reciprocating piston engine, the rotary engine works through the expansion pressure generated by combustion. It is transmitted to the crankshaft through the connecting rod, and the crankshaft rotates to output power outward. For a rotary engine, the expansion pressure pushes the rotor to rotate, and the force is transmitted to the main shaft through the rotor, and the main shaft rotates to output power outward.

The rotary engine does not generate reciprocating inertial force, has a compact structure, and the total number of parts and the number of moving parts are reduced by 30% and 60% respectively. It has the advantages of small size, light weight, good high-speed performance, stable operation, and low noise. But at the same time, the technology of the rotary engine is relatively advanced, and the machining accuracy of the rotor and the cylinder block is high, and the manufacturing cost is high. More importantly, the fuel consumption of the rotary engine is large, which is mainly due to the fact that the shape of the combustion chamber of the rotary engine is not conducive to complete combustion, and the flame propagation path is longer, which increases the consumption of fuel and engine oil. In today's increasingly scarce energy, energy saving and emission reduction is the key advocated by the country and even the world. The low-speed power performance and fuel economy of rotary engines are lower than those of reciprocating engines.

Contents of the invention

The purpose of this utility model is exactly to provide a kind of high-efficiency mover motor for the above-mentioned deficiency of motor.

The utility model is composed of N (N=2, 3, 4...) groups of mover mechanisms and a main shaft with external teeth. Each mover mechanism is composed of a cylinder group, a mover, a crankshaft, and a mover reinforcement shaft. The cylinder group It is composed of M (M=3, 6) cylinders. The piston rods of M cylinders are respectively connected to M crankshafts through M mover reinforcement shafts. The center of the mover is equipped with a toothed power shaft hole. The main shaft is installed in the power shaft hole of the mover, and M cylinders (M=3, 6) are respectively connected with the mover, and the M cylinders are evenly distributed around the center of the power shaft with external teeth.

The center of the two movers 1 of the two sets of mover mechanisms forms an included angle of 180° with the center of the main shaft 2 with external teeth.

The present invention has the advantages that the mover motor has the following advantages compared with traditional reciprocating motors and rotary motors:

1) Avoid the energy loss of the piston crankshaft at the highest point and the lowest point like the inline four-cylinder engine.

2) The structure of the mover engine is more compact, the overall volume is smaller, and the output power is not lost due to the volume reduction.

3) Since there are two cylinders doing work at the same time at each moment, and there is no problem of the highest (lowest) point at the same time, the power is basically constant, which eliminates the problem of unsteady power in ordinary engines. Reduced vibration and noise, but also reduced fuel consumption.

4) Due to the short working range of the cylinder and the relatively large radius of the piston, the driving power is sufficient each time, and the change of the transmission mode improves the mechanical efficiency and reduces the fuel consumption.

5) The structure of the mover engine is changed, and the mover and planetary gear are added to replace the crankshaft as a new transmission mode, which simplifies the processing technology and reduces the cost of the engine.

6) The engine speed is high, so it can be used in sports cars and other fields that require high-speed engines.
