Detailed Description

In order that those skilled in the art will better understand the disclosure, the following detailed description is given with reference to the accompanying drawings.

Referring to fig. 1, fig. 1 is a schematic diagram of a front end gear train of a hybrid engine according to an embodiment of the present disclosure.

The front-end wheel train of the hybrid engine in the embodiment is suitable for a hybrid power system of a vehicle, namely, the hybrid power system is formed by mixing an engine and a motor 3, the motor 3 is a BSG (Belt-driven Starter/Generator) motor, the motor 3 can drive the engine to start and can be driven by the engine to generate power, the motor 3 is generally a 48V motor 3, the hybrid power system can realize the functions of starting, assisting, generating and energy recovery, the motor 3 outputs power in a starting mode and an assisting mode, and the motor 3 is in a generating mode in the generating and energy recovery mode.

In order to adapt to a hybrid power system, the front-end wheel system of the hybrid engine in the embodiment comprises a crankshaft damper 1 and a motor 6, the crankshaft damper 1 is connected to a crankshaft of the engine, the crankshaft of the engine drives the crankshaft damper 1 to rotate, and the crankshaft damper 1 is specifically of a belt wheel structure. This mix and move engine front end train still includes air compressor machine 5 and belt 2, and belt 2 encircles bent axle shock absorber 1, motor 3, air compressor machine 5, and bent axle shock absorber 1, motor 3, air compressor machine 5 realize the transmission through belt 2 promptly and connect. Like this, crankshaft damper 1 is connected through belt 2 transmission with motor 3, then motor shaft 31 of motor 3 can drive crankshaft damper 1 through belt 2 and rotate, starts the engine or accomplishes the helping hand then, also can drive motor shaft 31 rotation of motor 3 through belt 2 when the engine rotates, then plays the electricity generation function. The motor 3 and the crankshaft damper 1 can drive the air compressor 5 to work independently or together.

So set up, the belt 2 drive of three annex wheels sharing of crankshaft shock absorber 1, motor 3, air compressor machine 5 can normally realize the operation of air compressor machine 5 of 48V mixed-action system, the engine drive and the user demand of BSG motor 3 load, and the drive of all loads can be realized to a belt 3 promptly, and compact structure realizes reducing the emission of pollutant under the mixed-action mode.

With continued reference to fig. 1, the front-end wheel train of the hybrid engine further includes a first tensioner 4, the first tensioner 4 is specifically a two-way tensioner, the first tensioner 4 includes a first swing arm 41 and a second swing arm 42, the first swing arm 41 is provided with a first tensioning wheel 43, the second swing arm 42 is provided with a second tensioning wheel 44, the first tensioning wheel 43 and the second tensioning wheel 44 are pressed against the outer side of the belt 2, and the first swing arm 41 and the second swing arm 42 can be adjusted in position, so as to adjust the tensioning force.

As shown in FIG. 1, the radial dimension of the crankshaft damper 1 is much larger than the dimension of the motor shaft 31 of the motor 2, the two-way tensioner is provided to help increase the wrap angle of the belt 2 on the motor shaft 31 to provide sufficient transmission force and reliable transmission of the motor shaft 31, and the two-way tensioner can increase the necessary pressing force to ensure that the belt 2 is always tensioned.

When the motor 3 of the hybrid power system is in a starting and boosting working condition, namely the motor 2 actively rotates, the left belt part of the belt 2 between the crankshaft vibration absorber 1 and the motor 3 in fig. 1 is a tight edge, the first tension pulley 43 serves as an idler pulley at the moment, the belt 2 does not need to be tensioned, the right belt part of the belt 2 between the air compressor 5 and the motor 3 is a loose edge, and the second tension pulley 44 needs to be abutted against the outer side of the belt 2 to play a tensioning function. When hybrid power system's motor 3 was in the electricity generation and energy recuperation operating mode, motor 3 driven rotation, then in turn, the right side belt portion that belt 2 is located air compressor machine 5 and motor 3 is tight limit, and the left side belt portion that belt 2 is located between motor 3 and crankshaft damper 1 is tight limit, and first take-up pulley 43 need support the outside of tight belt 2 in order to exert the tensioning function, and second take-up pulley 44 then acts as the idler. So set up, can guarantee under various modes, the phenomenon of skidding can not appear in belt 2.

The tensioner 4 in this embodiment may be fixed to the motor 3, as shown in fig. 1, the tensioner 4 is fixed to the front end of the motor 3, and the first swing arm 41 and the second swing arm 42 are located on the left and right sides of the motor shaft 31 and the belt 2. However, it is understood that the tensioner 4 mainly needs its tensioning wheel to press against the outer side of the belt 2, so the tensioner 4 is not limited to be fixed to the motor 3, but may be fixed to other positions, such as the engine, but compared with the fixation to the engine, the fixation to the motor 3 does not need to modify the engine, so that the universality of the engine can be ensured, and even if the connecting piece for fastening the tensioner 4 is damaged, the engine does not need to be replaced, and the economy is better.

Further, in fig. 1, the crankshaft damper 1, the motor 3, and the air compressor 5 are distributed in sequence along the transmission direction of the belt 2, that is, in the clockwise direction in fig. 1. The transmission direction of the belt 2 is the transmission direction of the engine, generally, from the perspective of the front end of the engine, the engine is driven clockwise, and then the crankshaft damper 1, the motor 3 and the air compressor 5 are also distributed in sequence along the clockwise direction. Thus, the space layout is not easy to interfere with other wheel train components.

In addition, as shown in fig. 1, in one embodiment, the motor 3 is disposed above the crankshaft damper 1 and the air compressor 5. Arrange motor 3 in the top, compare to set up in the low position, protection motor 3 that can be better prevents that it from receiving the influence of external muddy water etc to extension motor 3's life. In addition, since the belt 2 located at the upper side needs to be provided with the tensioner 4 to provide a large pressing force, and the motor 3 is arranged at the top in fig. 1, the pressing force between the crankshaft damper 1 and the motor 3 is large, and the bearing of the general air compressor 5 is difficult to bear, so that the arrangement sequence in which the motor 3 is arranged at the top can prolong the service life of the bearing of the air compressor 5 better than other sequences. In specific fig. 1, crankshaft damper 1 is located the left side of air compressor 5 and also is higher than air compressor 5, and motor 3 corresponds to the top position between the two, and this kind of overall arrangement is comparatively compact.

In this embodiment, the crankshaft damper 1 may be a rubber damper wheel to have a damping function, which is beneficial to reducing vibration and noise.
