The anchor 10 linear generator-compressor set North pole up, on the lower end of which has a hinge 11, which connects him with the rod 12, to the output end of the rod is fixed a similar hinge 11, attached to the axis 13, the wheel 14, the axis 13 of the device is protected bellow 15, and the upper side is attached to the base of the vehicle 16, and the magnetic circuit of the stator is connected with reversed to each other opposite poles of postkantoren, and can be used as a source of additional electric power and compressed air vehicles.Known generator power source for tractor (ASTA) containing ferromagnetic cover, inside which there is a magnetic core with grooves along these grooves laid the primary winding and excitation winding, and the starter; on the ends of the caps set bearings for rotation of the mounting of the rotor, made in the form of ferromagnetic cylinder on the output shaft of which is secured a drive pulley. (Brezinski M. L. Alternators for automotive engines. M "Automotive", 1968. S. 108).The disadvantages of the devices having excitation windings of the starter motor and belt drive.As a prototype of the selected design of a linear generator vehicles containing attached to the base of the vehicle, the stator magnetic core and winding and an anchor in the form of a permanent magnet, which is connected through a rod with the axis of the wheel and mounted with the possibility of reciprocating movement of the inside winding (U.S. Pat. UK N 1457636, class B 60 K 25/10, 1976).The disadvantages of the prototype the design complexity, low UD is vanishing energy (fuel) and enhanced functionality with the movement of the transport device.The objective is achieved by connecting the armature of a permanent magnet linear generator compressor with the axis of the wheel and the stator with the base of the vehicle.This construction of the proposed generator is an additional source of Autonomous power, because the above connection allows you to have more electricity without fuel, furthermore, the presence of the annular permanent magnets in the upper and lower parts of the stator facing the same polarity to the anchor to prevent hard blows anchors on the top and bottom flanges of the stator, i.e., the ring magnets play a role of additional absorbers.The presence of the exhaust valve in the upper flange and the small gaps between the armature and the guide stator and machined therein an axial channel, create the opportunity for the compression of air between the top flange and butt-anchor and release it into the receiver.The drawing shows a General view of the inventive device, the magnetic circuit of the stator contains two magnetizing coil 1 wound on insulated frames 2, installed in ferromagnetic cylinders 3. On the ends of the coils 2 are 4 pole, resting on one hand the magnetizing coil 1, there are axial grooves, and a ferromagnetic cylinders 3 are separated by a nonmagnetic sleeve 7 with a radial hole, and the permanent magnets 5 are adjacent flange 8, which has an exhaust valve 9. The anchor 10 linear generator-compressor set North pole up, on the lower end of which has a hinge 11, which connects him with the rod 12, to the output end of the rod is fixed a similar hinge 11, attached to the axis 13 of the wheel 14; axis 13 of the device is protected bellow 15, and the upper side is attached to the base of the vehicle 16, and the magnetic circuit of the stator, consisting of elements 1 and 4, in radial cross-section has the shape of a letter "P" and is connected with reversed to each other unlike poles of permanent magnets 5, having the form of a hollow cylinder, so that the radial cross-section, together with the magnetic core, they form a shape resembling the letter "C" and between the poles of the permanent magnets 5 is non-magnetic guide 6 within which is installed anchor 10, is made in the form of a permanent magnet, the polarity of which is opposite to the polarity of the pole permanent magnets, and its length is less than the length of the non-magnetic guide 6.The linear generator to the sustainability of road coverage and speed, between the axis 13 of the wheel 14 and the base of the vehicle 16 mechanical vibrations occur. Through the rod 12 these vibrations are transmitted to the anchor 10 and he begins to make a reciprocating movement (fluctuate). As a result of these fluctuations in the magnetic field of the armature 10 crosses the coils of the magnetizing coils 1 and Indochinese EMF, i.e., the device works as a standalone power generator. At the same time, through the holes of the non-magnetic sleeve 7, which provides magnetic isolation between the magnetic fluxes of the upper and lower coils, air arrives in the axial channels nonmagnetic guide 6, and thence into the space formed by the internal surface of the upper annular permanent magnet 5, the flange 8 and the butt of the anchor 10. Since the air gap between the armature 10 and the non-magnetic guide 6 is very small, you can move the anchor up 10 is compressed air in the working cylinder, formed by an upper annular permanent magnet 5 and the flange 8. When a certain pressure in the cylinder, i.e., when the anchor 10 is in its extreme upper position actuates the valve 9 and releases the compressed air into the drive air, i.e., the device operates as a compressor. is all right known that like poles repel each other.Vehicles are widely used alternating current generators for supplying power to various consumers. However, they all require either a mechanical or electric drive, and this greatly complicates and increases the cost of construction of the generator and requires additional fuel costs.In the proposed design of the linear alternator-compressor this objective is achieved in that the anchor permanent magnet connected to the axle of the wheel and the stator is fixed on the base body of the transport device.Thus, the claimed design of a linear generator compressor allows it to achieve its goal of reducing energy consumption and enhanced functionality with the movement of the transport device.The use of the proposed linear generator compressor for vehicles allows to obtain high technical and economic effect resulting from the reduction of the cost parameters and the creation of more favorable conditions (cab heating, cooling, engine, swap the wheels and so on) to work and travel in the transport device.

SUBSTANCE: during vehicle motion elements of its suspension move by reciprocating motion. At impact to plates 10, 11 at straight-line portions 4 and 5 by alternating force the latter start moving bending the stator in the arc 3 area making poles 8 and 9 approaching or removing from each other. Due to residual magnetic induction or due to permanent magnet in stator 1 magnetic field F is induced. When gap changes intensity of the magnetic field changes as well, either increasing or decreasing. It leads to change in induction and this in magnetic flux F. In compliance with Maxwell formula electromotive force is induced in armature winding 7, which comes after rectifier to the onboard network and accumulator may be used as such network. Due to generated electromotive force current appears in excitation winding 6, which leads to increase of magnetic flux in the stator.
