(57) Abstract:

Usage: the invention relates to vehicles and will allow you to create a short-term necessary torque on the crankshaft of the engine without the expense of muscular energy or lack of capacity of the battery. The inventive actuator device comprises a drive shaft with the pin at one end, a housing with a Central hole for the drive shaft that holds the drive drum with lisovanim Central hole slots of the drive shaft and the hole stopper, stopper with lock, winding drum with a ring gear and ratchet wheel, torsion spring, one end fixed on the drive drum and the other on the winding drum, gear knob, manual focus, shutter with a hinged stop, telescopic casing, the other end of the drive shaft is made neck, which is installed and fixed in the axial direction of the supporting disk mounted on it, the other end of the telescopic casing. 6 Il.

The invention relates to vehicles, and in particular to structures starting devices for internal combustion engines (starters), used for prio combustion, representing a starting handle, consisting of a shaft with cotter [1] the downside of it is the need for great physical cost to start the engine.

Know the starting device of an internal combustion engine, containing a drive shaft, one end of which is fixed the check and at the other end of the neck is made on which is installed and fixed in the axial direction of the supporting disk, and a housing with a Central hole for the drive shaft and placed in it driving drum with a Central hole and a stopper with lock, winding drum with a ring gear and a locking mechanism, a clockwork spring, one end fixed on the drive drum and the other on the winding drum, the gear with handle, meshing with a ring gear winding drum [2]< / BR>
The disadvantage of this solution is that it is not very secure, as it has exposed rotating parts, and is not universal, as the drive shaft is limited in axial movement, which does not allow you to install the device on vehicles having different distances between the open end of the crankshaft and the outer parts of the vehicle.

The result,as.

To achieve the specified result of the proposed starter device of an internal combustion engine, containing a drive shaft, one end of which is fixed the check and at the other end of the neck is made on which is installed and fixed in the axial direction of the supporting disk, and a housing with a Central hole for the drive shaft and placed in it driving drum with a Central hole and a stopper with lock, winding drum with a ring gear and a locking mechanism, a clockwork spring, one end fixed on the drive drum and the other on the winding drum, the gear with handle, meshing with a ring gear winding drum, this drive shaft is made with splines, the drive drum is made with holes in the stopper, and its Central hole is made lisovanim under the splines of the drive shaft, the locking mechanism of the winding drum is made in the form of ratchet wheels mounted thereon, and a ratchet pawl mounted on the housing, equipped with manual focusing, cover with a hinged stop, telescopic casing, one end fixed on the supporting disk and the other on the body.

In Fig.1 shows a longitudinal section of the starter; f is the cut b-b In Fig.1; in Fig.6 the node I in Fig.1.

Starting device of an internal combustion engine includes a housing 1, in the Central hole of which is placed the drive shaft 2 with the pin 3, the slots 4 and neck 5. Slots 4 driving shaft 2 is connected with the splined drive pulley 6, in which the holes 7 under the stopper 8. The stopper 8 can enter the holes 7 or leave them, thereby fixing the drum or freeing it for rotation relative to the housing 1. Fixing stopper 8 in a particular position by means of latch 9, for example a ball. On the neck 5 of the drive shaft 5 has a supporting disk 10 is fixed in the axial direction, for example, by a nut 11. On the supporting disk 10 is fixed to one end of the telescopic casing 12, the other end of the casing 12 is mounted on the housing 1. When exposed hand on the supporting disk 10 in the axial direction you can move the drive shaft 2 in this direction even when its rotation together with the driving drum 6, thereby carrying out the variation of size L, which depends on the distance between the bumper and the output of the crankshaft of the engine. Telescopic casing 12 allows such movement, protecting the driver from the rotating drive shaft. Soon the Oia 14, with which is engaged the gear 15, mounted in the housing 1. Gear 15 can be brought into rotation by means of the handle 16. The handle can be made foldable. Inside the housing 1 posted by winding spring 17, one end 18 mounted on the drive drum 6, and the other end 19 on the winding drum 13. On the winding drum 13 is mounted ratchet wheel 20 and the ratcheting pawl 21 mounted on the housing 1. On the housing 1 is set to manual focus 22, a cap 23 with a hinged stop 24. The drive shaft 2 in the off position is stored in the vehicle.

The device operates as follows.

The drive shaft 2 is inserted into licowania hole of the drive pulley 6, is passed through the Central hole in the casing and enter the neck 5 in the supporting disk 10 with the subsequent fastening of the shaft 2 in the axial direction relative to the reference disk 110 by means of nuts 11.

The stopper 8 is withdrawn from engagement with the holes 7 of the drive pulley 6 and through the retainer 9 is fixed in its upper position. The spring 17 is in a lowered position (see Fig. 3). The drive shaft 2 is injected prior to the engagement of its end with the pin 3 output of the crankshaft of the engine, the plug 22 operae the bottom of the holes 7 in the drive drum 6, thereby locking the drive drum 6 with the drive shaft 2 relative to the housing 1. The stopper 8 in this position, is secured against inadvertent movement along its axis upward by the retainer 9. Using manual focus 22, provides contact flip stop 24 with the bumper of the car. Rotating the handle 16, having a spring 17 (see Fig. 4). In the opened state, the spring 17 can't spontaneously go in the released state (see Fig. 3) because one end 18 mounted on the drive drum 6, is fixed relative to the housing 1 by means of the stopper 8 and the other end of the spring 19 cannot be rotated in the direction opposite to the direction of winding of the spring, due to the presence of ratcheting mechanism consisting of a ratchet wheel 20 and the ratchet pawl 21, which allow you to rotate the winding drum 13 in the direction of winding of the spring 17. Then, working with one hand on the hand rest 22, press the hinged stop 24 to the bumper of the car, and the other hand translate the stopper 8 from the lower to the upper position, a locking pawl 9, while the drive pulley 6 is able to rotate under the influence of repressurise the end of the spring 18.

Benefits device compared to overselect, as the drive shaft with the splines has the ability to move in the axial direction, thereby the device can be installed on various vehicles regardless of the distance between the end of the crankshaft and the outer parts of the vehicle.

Starting device of an internal combustion engine, containing a drive shaft, one end of which is fixed the check and at the other end of the neck is made on which is installed and fixed in the axial direction of the supporting disk, and a housing with a Central hole for the drive shaft and placed in it driving drum with a Central hole and a stopper with lock, winding drum with a ring gear and a locking mechanism, a clockwork spring, one end fixed on the drive drum and the other on the winding drum, the gear with handle, meshing with a ring gear winding drum, characterized in that that the drive shaft is made with splines, the drive drum is made with holes in the stopper, and its Central hole is made lisovanim under the splines of the drive shaft, the locking mechanism of the winding drum is made in the form of ratchet wheels mounted thereon, and a ratchet pawl mounted on corpu on the supporting disk, and the other on the body.
