Description

Technical Field

[0001] The present invention relates to the technical field of engines, and in particular to an electric balancing module suitable for a three-cylinder engine. Background Art

[0002] With the development of science and technology, people have higher and higher demands for the functions and comfort of cars. Traditional fuel vehicles still account for a high proportion in the automobile market. As we all know, the vibration and noise of the engine at work are very large, which brings a bad experience to the surrounding environment and the driver and passengers. The three-cylinder engine will generate a huge inertia moment because the phase angle of the three-cylinder piston is 120°. It will cause very serious vibration to the engine, which has a very bad impact on the driving experience and the engine itself.

[0003] Therefore, the present invention proposes an electric balancing module suitable for a three-cylinder engine, which can effectively balance the inertia moment of the engine and can greatly reduce the vibration and noise of the engine. Summary of the invention

[0004] The technical problem to be solved by the present invention is that the existing three-cylinder engine has a large noise, which leads to a decrease in the comfort level of passengers.

[0005] In order to solve the above technical problems, the technical solution of the present invention is to provide an electric balancing module suitable for a three-cylinder engine, including a balancing block, a motor, a main shaft, a bearing, a control board and a module housing. The motor is arranged in the module housing, including a motor housing, a stator winding and a rotor. The rotor is arranged in the stator winding. The rotor is a main shaft with a permanent magnet. Both ends of the main shaft extend out of the motor housing and the module housing. Bearings are arranged between the main shaft and the module housing. The balancing blocks are arranged at both ends of the main shaft. The control board is located outside the module housing, the control board is connected to the motor, and the module housing is connected to the external engine.

[0006] Optionally, the motor housing and the module housing are connected by bolts, and the module housing is aluminum die-casting.

[0007] Optionally, the bearing includes a large bearing and a small bearing, and the large bearing and the small bearing are respectively arranged at the connection between the two ends of the main shaft and the module housing.

[0008] In summary, the electric balancing module for the three-cylinder engine provided by the present invention generates an unbalanced torque opposite to the engine through the motor, effectively reducing the vibration and noise of the engine. It has a simple structure, does not require a complex gear structure, does not require a corresponding phase angle during assembly, and is easy to install. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The following combination Figure 1 The present invention is described in further detail.

[0012] The present invention discloses an electric balancing module suitable for a three-cylinder engine, which is suitable for noise reduction and vibration reduction of the three-cylinder engine. Figure 1 , including a balancing block 1, a motor 2, a main shaft 3, a control board 5 and a module housing 6. The motor 2 is arranged in the module housing 6, including a motor housing 21, a stator winding 22 and a rotor. The rotor is arranged in the stator winding 22. The rotor is a main shaft 3 with a permanent magnet. The main shaft 3 is an unbalanced structure around the rotation center. Both ends of the main shaft 3 extend out of the motor housing 21 and the module housing 6. Due to the irregular structure of the main shaft 3, a large bearing 4 and a small bearing 7 are respectively provided at the connection between the two ends of the main shaft 3 and the module housing 6, which are used to support the main shaft 3 and reduce the friction force of the shaft rotating in the assembly. Generally, it is interference fitted into the module housing 6. The balancing block 1 is arranged at both ends of the main shaft 3 to form a torque opposite to the engine to offset the torque generated by the engine. The control board 5 is located outside the module housing 6, the control board 5 is connected to the motor 2, and the module housing 6 is connected to the external engine. The motor housing 21 and the module housing 6 are connected by bolts, and the module housing 6 is aluminum die casting.

[0013] When the present invention is in use, the module is installed near the engine, and the engine will generate a reciprocating inertia torque. The control board 5 will read and collect the phase position of the engine rotation and the rotation speed of the crankshaft, and input the relevant signals to the motor 2, synchronously control the motor speed and phase, so that the main shaft 3 rotates to generate an unbalanced torque to offset the unbalanced torque of the engine, thereby reducing the noise and vibration of the engine.

[0014] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
