Description

  The present invention relates to a composite power unit, and more particularly to a composite power unit for a vehicle engine.

  In an engine used in a mobile vehicle, the starter and power generator are typically combined to start the engine and provide the necessary electrical load or battery charge during engine operation.

As an example, the prior art document discloses a starter / power generator used in a vehicle engine, where a starter coil and a generator coil are provided in a stator of a motor, and power is supplied to the starter coil from a battery at the time of start. The supplied motor is used as a starting device, and the engine is started by directly connecting the motor to the crankshaft to drive the rotation of the crankshaft (see, for example, Patent Document 1). On the other hand, the commutator and the brush mechanism of the motor come into contact with each other by the adjusting mechanism, and when the rotor reaches a predetermined rotational speed as the engine speed increases after the engine starts, The adjustment mechanism is activated to disconnect the contact with the commutator and the brush mechanism, whereby the motor is used as a power generator, and the electromotive force generated from the power generation coil is supplied to the electric load of the vehicle to charge the battery. Do.

Adopting a starter / generator composed of a brush-type motor requires the use of an adjustment mechanism and a brush mechanism, so that a large space is placed on the crankshaft and the length of the crankshaft can be shortened. It was gone. Therefore, another prior art document discloses a vehicle starter / generator, which is applied to a vehicle engine having a continuously variable transmission and a centrifugal clutch, and a brushless motor is mainly used as a crank of the engine. It is arranged on the shaft, and a brushless motor stator has an inner rotary structure in which the stator is arranged on the outer periphery of the rotor, and further, a rotor sensor is arranged on the outer periphery of the rotor so as to face the inside of the stator, Engine start-up or power generation is controlled by a combination of the rotor sensor and, for example, a Hall sensor element. By adopting a brushless motor, it is not necessary to use an adjustment mechanism and a brush mechanism, so the arrangement space on the crankshaft is reduced, the length of the crankshaft is shortened, and the width of the vehicle is reduced accordingly. It is possible to reduce the weight of the vehicle (for example, see Patent Document 2).
JP-A-11-111010

With the advancement of the vehicle industry, the power of the vehicle is provided by an engine (internal combustion engine), and an auxiliary combined power system in which a combined power unit is integrated in the engine is developing. Another prior art document includes an engine start-and-assist to allow the engine to start and assist torque so that torque assistance is provided, for example, when the vehicle is climbing up or when a large torque output is needed immediately. An apparatus is disclosed (for example, see Patent Document 3). In addition, with the growing awareness of energy crisis and environmental protection, in the new auxiliary combined power system that is widely applied, the engine is shut down when idling and the ignition is started when the vehicle starts moving A shutdown and start (Stop-Go) function has been introduced. For example, yet another prior art document states that to save energy and reduce air pollution, the engine automatically shuts down when the vehicle is stopped and the engine is idling when the vehicle is idling. An engine start and stop device for use in a vehicle that is started by ignition is disclosed (see, for example, Patent Documents 3 to 5).

  As shown in FIG. 1, the auxiliary combined power system 10 reduces the required space and shortens the length of the crankshaft by connecting the motor generator 12 and the crankshaft 13 of the engine 11 coaxially. To do. Further, as an air-cooled engine, the motor generator is disposed at one end of the engine 11 away from the output power (transmission 14), and is further connected to a cooling fan, so that the length of the crankshaft is increased. There is no need and space is utilized more effectively.

  The motor generator 12 used for starting, power generation, and auxiliary power is roughly classified into an internal rotation type and an external rotation type according to the structure. Among them, the external rotation type does not require the use of a carbon brush as a rectifying element, and is often seen. In the outer rotating structure, the coil of the motor generator 12 is fixed inside, and the magnet surrounds the outer periphery. Since the coil is fixed inside, it is called a coil stator 121, and since the magnet surrounds the outer periphery, it is called a magnet rotor 123. The coil stator 121 is fixed inside the case of the engine 11 so that the crankshaft 13 penetrates, and the magnet rotor 123 is fixed to the crankshaft 13 and surrounds the coil stator 121 corresponding to the outer periphery thereof.

  In such a motor generator 12, it is necessary to provide a signal generation device for generating two types of timing signals, that is, a timing signal for engine ignition and a timing signal for the magnetic field phase when the motor is driven. These two types of timing signals are intermittent voltage signals that are generated when the Hall effect sensor and the magnetic ring interact with each other. Here, the Hall effect sensor is held in a fixed state, and the magnetic ring rotates in synchronization with the crankshaft 13 of the engine 11. However, in the prior art, since the signal generating device is provided in the vicinity of the coil stator 121 and is shielded by the magnet rotor 123 having a bowl shape, there are various drawbacks.

FIG. 2 schematically shows an enlarged view of the local structure of the auxiliary combined power system 20 which is a conventional outer rotating structure. As shown in the figure, in this outer rotary structure, the coil stator 22 is provided inside the engine case so that the crankshaft 21 penetrates, and the magnet rotor 23 is fixed to the crankshaft 21 and the outer periphery of the coil stator 22 is shown. Surrounding it in response to. The signal generation device 24 for generating these two types of timing signals is disposed on the side near the engine case in the vicinity of the coil stator 22, that is, adjacent between the high-temperature engine case and the coil stator 22, It is shielded by a magnet rotor 23 having a bowl-like structure.
As described above, the arrangement position of the signal generating device 24 of the conventional auxiliary combined power system 20 can use a tight space, but it is adjacent between the hot engine case and the hot coil, And since it is shielded by the magnet rotor 23 and difficult to be cooled by air from the outside, it is easy to lose its effectiveness in a high temperature environment, and a special sensor that can withstand high temperatures is used. If so, the cost will increase. In addition, since the signal generator 24 is disposed extremely inside the entire auxiliary composite power system 20, if a part is damaged, its maintenance or replacement is very troublesome and the maintenance cost is high. It becomes. At the same time, since the signal generating device 24 is provided in a sealed position inside, it is impossible to adjust from the outside of the auxiliary combined power system 20 at all. The fine adjustment of the angle cannot be performed, and it is not easy to control the accuracy of the timing signal, and the effects of starting the motor generator, power generation, and auxiliary power are reduced.

  Therefore, it is an extremely important issue in the industry to effectively solve the various drawbacks of the prior art.

  Therefore, in view of the circumstances as described above, an object of the present invention is to provide a composite power unit for an engine in which a component that generates a timing signal is separated from a high temperature environment and damage due to high temperature can be avoided.

  It is another object of the present invention to provide a composite power unit for an engine that can reduce the cost of components without using components of a level that can withstand high temperatures in components that generate timing signals.

  It is another object of the present invention to provide a composite power unit for an engine for facilitating maintenance or replacement of components that generate timing signals.

  Another object of the present invention is to provide a composite power unit for an engine for facilitating the fine adjustment of the timing angle.

  In order to solve the above problems, a composite power unit for an engine according to the present invention includes a crankshaft having a first end to be connected to the composite power unit and a second end to output power. In a composite power unit of an engine applied to an engine, a coil stator that is fixed to the engine and through which the crankshaft passes, and a coil stator that is fixed to a first end of the crankshaft and that corresponds to the outer periphery of the coil stator. A motor generator having a cage structure in which the magnet rotor has an opening facing the second end, and the magnet rotor is coaxially provided on one side farther than the second end. Provided in the motor generator and a sensor for providing a detection signal of any one of the phase angle of the motor generator and the ignition timing of the engine. And a server and, the.

  The motor generator has a motor generator case, and the sensor is provided on the inner side of the motor generator case far from the second end. Preferably, a fixed frame for mounting the sensor is provided on the inner side of the motor generator case, and the fixed frame may have a ventilation hole for drawing in external air to perform cooling. Further, a centrifugal fan, for example, is further coaxially provided on one side of the magnet rotor farther from the second end, and heat exchange can be performed by guiding cooling air from the outside faster.

  The sensor may be provided on one side of the motor generator that is farther from the second end and faces the induction magnet. The sensor includes at least one support plate and a timing detection element and a phase detection element provided on the support plate, or a plurality of support plates and a timing provided corresponding to each of the support plates. A detection element and a phase detection element may be provided. Here, the support plate has a position adjusting unit for adjusting a fixing position of at least one of the support plates, and the position adjusting unit is configured such that the bolt is locked and the lock position of the bolt is adjusted. It may be a wide lock hole provided on the surface of the support plate. On the other hand, the induction magnet is provided with a winding position magnetic induction ring and a timing position magnetic induction ring corresponding to the phase detection element and the timing detection element, respectively. Any one of the ignition timing detection signals is provided.

  Compared with the prior art, in the composite power unit for an engine according to the present invention, for example, the induction magnet is farther from the second end of the magnet rotor so that a part for generating a timing signal is separated from the engine. Since it is provided coaxially on one side and the sensor is provided on one side of the motor generator far from the second end and opposed to the induction magnet, both the sensor and the induction magnet are a coil stator or a magnet rotor. Not to be shielded by the heat radiation of the engine case, it is possible not only to be affected by the heat radiation of the engine case, but also to perform heat exchange using the external cooling air sufficiently, and the temperature of the environment is lowered. The parts can be prevented from being damaged by high temperatures and the use of high temperature resistant parts is not required, which reduces the cost of the parts. It is possible to reduce the width. In addition, since the components for generating the timing signal are provided extremely outside the entire composite power unit, it is possible to expose the components by removing the fan cover of the motor generator case. Alternatively, the replacement becomes easy and it is advantageous to perform the fine adjustment of the timing angle mechanically with respect to the timing signal, so that various problems of the prior art can be solved.
