Below in conjunction with accompanying drawing the preferred embodiments of the invention are described.
As shown in Figure 3, the present invention is used for the alternating current generator of vehicle and is made up of a main body 10, wherein, is provided with a pair of front rack 11 and tail-bracket 12.There is an axle 13 in the central authorities of main body 10, and this a end stretches out front rack 11.A belt pulley 14 is contained on this end of axle 13.Pair of bearings 15,16 is arranged at the two ends of axle 13, axle 13 by its rotatably support.Around rotor 20 and its formation one that axle 13 is provided with, rotor 20 can produce magnetic field and rotate synchronously with axle 13.What separate with the periphery of axle 13 is stator 30, and it is installed in main body 10 the insides, so that interact with rotor 20.Coil 31 is wrapped in around the stator 30.Be provided with a pressurizer 50 in tail-bracket 12 outsides, voltage maintained predetermined value by it; Also be provided with a rectifier 80, so that alternating current is changed into direct current.In addition, an end cap 70 is housed also on tail-bracket 12, covers and protection pressurizer and rectifier by it.And, cooling fan 17,18 is installed in each end of rotor 20, when rotating alternating current generator is cooled off with convenient rotor 20.Be provided with some air circulation hole 40 on main body 10 and end cap 70, the rotation by cooling fan 17,18 circulates air in these holes.
The alternating current generator that is used for vehicle in the present invention who makes in the manner described above, belt pulley 14 is connected with an engine (not shown) by belt, and the revolving force of engine passed to axle 13, axle 13 is being supported smoothly by fore bearing 15 and rear bearing 16 and is rotating.Meanwhile, can produce magnetic field, therefore produce output current by stator 30 because rotor 20 rotates.Electric current is transported to rectifier 80,, carries out rectification by coil 31 here.At last, be delivered to the electric component of vehicle through pressurizer 50 through the electric current of over commutation.In the course of the work, along with the rotation of the fan 17,18 that is arranged on stator 20 two ends, extraneous air enters in the described alternating current generator and circulates by being located at hole on main body 10 and the end cap 70, thereby makes the alternating current generator cooling.
In described alternating current generator, the first kind of embodiment that is used for alternating current is changed into galvanic rectifier of the present invention will be illustrated in conjunction with Fig. 4,5 and 6.
Rectifier 80 of the present invention has a pair of fin that is used to dispel the heat, and the two ends of each fin all are connected with the two ends of another radiator.Between fin 81, be provided with a pair of emission part 82 that is used for alternating current is carried out rectification.Be provided with terminal block 83 (on the right side of Fig. 6) in fin 81 back.A joint 84 is arranged on terminal block 83, and it is with emission part 82 and coil 31 and is electrically connected.At the two ends of terminal block, be provided with a protrusion 87, be used for the assembling of terminal block 83 and fin 81.
In described alternating current generator, above-mentioned rectifier is to install like this: make the hole 42 of fin 81 towards end cap 70, and the stator 30 of terminal block 83 in placing main body 10, as shown in Figure 3.Therefore, when the hole 42 of air on end cap 70 enters in the alternating current generator, can pass through fin 81 in the clear, thus the cooling alternating current generator.Because the position of terminal block 83 and stator 30 is approaching mutually, therefore, connects their required loop lengths and lacks than the requirement in common technology.For to insulating, insulator 85 is set around coil 31 from the tail-bracket 12 of main body coil 31 by tail-bracket 12.This insulator 85 is tubuloses, begins to extend by the one side of terminal block 83, and by tail-bracket 12.
A fixture 86 is set,, is connected with joint 84 as welding manner so that the part of the coil 31 by insulator 85 is easy to by connected mode.Fixture 86 is with the form moulding of another extension of joint 84, and is set at around the insulator 85.Fixture 86 is the disc upper bifurcation on insulator 85, subsequently towards bonnet 70 bendings.Fixture 86 can by coil 31 from insulator 85 by after with the position of its mode fixed coil of pushing down 31.In addition, for being electrically connected between ballast coil 31 and the joint 84, adopt such as soldering, welding, the fixed form riveting or being threaded.Therefore, can assemble described coil with full automatic mode.
Second kind of embodiment of Fig. 7 and 8 expressions ac generator of vehicle of the present invention, wherein, Fig. 7 is the front view corresponding to the rectifier of Fig. 4, and Fig. 8 is the side view cutaway drawing of this rectifier.
As shown above, a pair of fin that is used to dispel the heat 81 is set, and a pair of emission part 82 that is used for alternating current is carried out rectification is set between fin.With the same in first kind of embodiment of the present invention, rectifier is to install like this: make the hole 42 of fin 81 towards end cap 70, and terminal block 83 is arranged near stator 30 places that place main body 10, as shown in Figure 3, produces the same advantage that surpasses prior art thus.Joint 84 is inserted on the terminal block 83, to realize being electrically connected of emission part 82 and coil 31.
Because coil 31 is to be connected with terminal block 84 by the tail-bracket 12 of main body 10, wound coil 31 peripheral insulators 85 that are provided with can play the effect of coil 31 with tail-bracket 12 insulation of main body 10.Insulator 85 is to have near the part of the strain plate 83 the tail-bracket 12 of main body of being arranged on 10 to form.This part is a tubulose, and passes through the tail-bracket 12 of main body 10, and it passes through tail-bracket side by side with coil 31.In order to support and fix the coil 31 by insulator 85, endways 84 places perpendicular to fin a fixture 86 ' is set, establish the outside that fixture is located at insulator 85 front ends.Fixture 86 ' has two branches, and insulator 85 is installed between the branch, and at the lower limb of terminal block 83 a groove 83a is set, and fixture 86 ' makes and inserts in this groove.It is desirable to, the edge of groove 83a places the reverse side of insulator as the basis of described projection, with example described insulator is firmly held between the described projection.In the rectifier of said structure, if the coil that is connected with joint 84 31 passes through insulator 85, and extend to the front end of insulator 85, can at first determine the position of coil 31 by the mode that is fixed part 86 '.Specifically, because the formation of described groove makes the process of utilizing hold down gag to be fixed part 86 ' become so not complicated.Therefore, being connected between fixture 86 ' and the coil 31 becomes more stable, and, they be with such as soldering, welding, rivet or the mode that is threaded realizes being electrically connected.
Book is described as described above, is used for the alternating current generator of vehicle in the present invention, and fin is provided with towards end cap, and terminal block is towards definition.In addition, tubular insulator is made up of the part of terminal block, and forms the insulation between coil and the main body.Fixture is arranged on an end of joint, and forms the concrete installation of coil by described insulator.
Therefore, directly contact with fin owing to enter the air of alternating current generator the hole from end cap, heat can leave effectively.In addition, because terminal block is near the stator setting, connects both required loop lengths and be shortened, thereby reduced production cost.
In addition, described insulator is to be formed by the terminal block that is provided with near described main body, thereby has reduced the required component count of insulator, can also reduce production costs.
The employing of fixture can realize the automatic of assembling process, and so that the technology of a single jointing and coil to be provided, this fixture passes through afterwards coil location from insulator at coil.
In addition, since the fixture that stretches out from the insulator end around groove, the insertion of the fixture more aspect that becomes is arranged.Like this, correctly jointing and coil, and can avoid inserting the difficult problem of fixture.At last, fixture is to extend from the part of joint, because have the advantage that is easy to produce.
