Description

The utility model relates to starting devices for internal combustion engines (ICE), namely to starter drives, the need for which arises in the event of a vehicle battery discharge.

A drive for a starter of an internal combustion engine is known (see US Patent No. 2933077A, published on 19.04.1960), comprising a hollow housing, end and side walls, a first shaft, a first bevel gear connected to the first shaft, a spiral spring resting against the first bevel gear, a stopper, a crank handle protruding outside the housing, a second bevel gear forming a bevel gear with the first bevel gear, a device ensuring the safety of the user at the moment of starting the engine. Disadvantages include the need to apply physical effort, which in some cases is impossible, as well as the need to provide a place for connecting and rotating the crank handle.

A drive for a starter of an internal combustion engine is known (see US Patent No. 4,615,311A, published on October 7, 1986), including a pair of rotating drive elements, driven by a manual or power device, wherein the manual device consists of a cable wrapped around a pulley, which must be pulled to rotate the pulley and then start the engine, wherein the power drive element is connected to the crankshaft through a primary overrunning clutch, and the manual drive element is connected to the crankshaft through a primary clutch, as well as a secondary overrunning clutch, wherein the secondary clutch is connected in series with the primary clutch. The known drive provides for the possibility of using a power device, for example an electric drill, to start the engine, which solves the problem of applying physical effort. The overrunning clutch ensures the safety of the user at the moment the internal combustion engine starts operating. The disadvantages of the known drive are its stationary installation, which does not allow connecting the drive device with the power device in different positions, which reduces the versatility of the drive. Also, the lack of a gear transmission reduces the ability to start more powerful internal combustion engines, such as automobile engines.

The objectives of the claimed technical solution are to create a universal drive device for an internal combustion engine starter, used for various types of vehicle hoods, to improve ease of use, and to eliminate the shortcomings of known technical solutions.

The stated problem is solved by creating a drive device for a starter of an internal combustion engine, containing an axle with bearing supports supporting it, an overrunning clutch installed on the axle and a first bevel gear, while containing a rotary plate on which the housings of the bearing supports are fixed and a second bevel gear is installed, forming a bevel gear transmission with the first bevel gear.

A drive device for a starter of an internal combustion engine in which the bevel gear ratio is in the range from 1:2.5 to 1:5.

A drive device for a starter of an internal combustion engine in which holes are formed in the rotating plate.

A drive device for a starter of an internal combustion engine in which the holes are round or arcuate.

The essence of the utility model is revealed in the figures and in the description.

Fig. 1 - Drive device of the starter of an internal combustion engine in a vertical position in section.

Fig. 2 - Drive device of the starter of an internal combustion engine in a horizontal position.

Fig. 1 shows a drive device of a starter of an internal combustion engine in a vertical position in section, containing an axis 1, on which a first bearing support 2 is mounted, a second bearing support 3, an overrunning clutch 4, a first bevel gear 5 which is a driving gear, also containing a second bevel gear 6 which is a driven gear, a rotary plate 7 in which openings 8 are made. The inner rings of the bearings of supports 2 and 3 are fixed on the axis 1, and the outer rings are fixed in the housings of the bearing supports 2 and 3. The axis of the second bevel gear 3 is fixed in the bearing, which is installed in the rotary platform 7. The overrunning clutch 4 contains a tip 9 in the form of a hexagon for connection with a corresponding attachment of a power tool, for example a cordless drill or screwdriver. The drive device of the internal combustion engine starter is secured by the rotary platform 7 to the starter 10 using fasteners 11, such as threaded studs or bolts. The housings of the bearing supports 2 and 3 are secured to the rotary platform by four fasteners 12, such as threaded studs. The openings 8 made in the rotary platform 7 have an arcuate shape, which allows, when the fasteners 11 are loosened, to turn the drive device of the internal combustion engine starter to the required angle and provide access for a power tool, such as an electric drill, to the tip 9 on the overrunning clutch. The drive device of the internal combustion engine starter with a rotary platform can be used with different types of engine compartment layouts of vehicles. In the vertical position shown in Fig. 1, the drive device is installed on a bonnet vehicle. When the bonnet is opened, it is possible to access the tip 9 of the drive device from above. The design of the overrunning clutch 4 ensures the safety of the person accelerating the engine starter with a drill at the moment the engine starts to operate.

Fig. 2 shows the drive device of the internal combustion engine starter in a horizontal position, allowing access to it and the tip 9 from the side. This position of the drive can be used in cabover vehicles, in which access from above to the starter is limited by the design of the underhood space. To rotate the drive device to the position shown in Fig. 2, it is necessary to loosen the fastening elements 11 pressing the rotary platform 7 to the starter 10, rotate the drive device by 90 degrees and fix it with the fastening elements 11 in the new position. The holes 8 made in an arcuate shape allow the fastening elements 11 to move freely along them and rotate the drive device to any desired angle. The holes 8 can be made round, and to change the position of the drive device, it will be necessary to completely unscrew the fastening elements 11 from the mounting holes in the starter 10.

The drive device of the internal combustion engine starter operates as follows. In case of insufficient battery charge, additional force is required to accelerate the internal combustion engine starter. Such a situation may arise, for example, if some electrical appliance is switched on in the vehicle for a long time, the engine does not work and the battery, accordingly, does not charge. In order to spin the starter 10 to the required speed and start the engine, it is necessary to connect the appropriate attachment of the battery drill or screwdriver to the hexagonal tip 9 of the overrunning clutch 4. When starting the drill, the torque is transmitted through the overrunning clutch 4, axis 1, the first bevel gear 5, the second bevel gear 6, forming a bevel gear transmission to the shaft of the starter 10. After the shaft of the starter 10 spins up to the required speed, the internal combustion engine starts. At the same time, the overrunning clutch 4 protects a person from injury by not letting high engine speeds pass through itself to the projection 9 of the overrunning clutch 4 and, accordingly, the drill that a person is holding in his hands. After the engine has gained the necessary speed and started, the drill can be removed from the drive device.

The experimental results showed that the optimal gear ratio of the bevel gear is in the range from 1:2.5 to 1:5 in favor of the driven gear, and the best ratio is 1:4.

Thus, the developed drive device of the internal combustion engine starter allows, with the help of an additional power device in the form of a battery drill or screwdriver, to start the internal combustion engine without using physical force, while the presence of an overrunning clutch increases the safety of operation, and the presence of a rotary platform makes the drive device universal for use in various types of vehicle hood designs.
