Description

The star-like retarding starter of passenger car diesel

Technical field

It the utility model is related to starter used for diesel engine on a kind of car, and in particular to a kind of passenger car diesel star Type retarding starter.

Background technology

Car with diesel engine is in engine start, it is necessary to which larger torque, in general starter rotating speed are high Moment of torsion is small can not to be met to require, and the narrow space in the engine bin of car, the direct current generator external diameter in original starter It is too big, main reason is that the rotor outer periphery surface cover on motor is connected in the inner ring of brush holder so that starter volume increases, it is impossible to The inner space of the engine bin of maximal efficiency, cause engine interior space very narrow, influence the installation effect of parts Rate, it is therefore necessary to redesign the overall structure of starter.

The content of the invention

To solve the above problems, to be to provide a kind of torque big and effectively reduce the sedan-chair of volume for the purpose of this utility model The star-like retarding starter of car diesel engine.

To achieve the above object, the utility model provides following technical scheme：A kind of passenger car diesel is star-like to slow down Motivation, including housing, direct current generator, isolator and electromagnetic switch, described direct current generator and the isolator are arranged on shell In intracoelomic cavity, described electromagnetic switch is arranged on the side of the housing, is set between described electromagnetic switch and the isolator There is wishbone lever, there is rotor, stator and carbon brush component on described direct current generator, the afterbody of the rotor is provided with commutation Device, the commutator segment of the commutator are arranged on the end face of the rotor afterbody, and described carbon brush component is arranged on institute as end cap The aperture position of housing is stated, there is carbon brush, described carbon brush is positioned axially and presses in the rotor in the carbon brush component On the commutator segment of tail end face, there is armature shaft on described rotor, tooth is provided between the armature shaft and the isolator Wheel decelerator.

Described gear reduction unit includes fixed seat, ring gear, drive shaft and the row being connected in the housing cavity Star gear, described fixed seat are fixedly connected integrally with ring gear, and described drive shaft passes through described fixed seat, the drive One end of moving axis is provided with terminal pad, and described terminal pad is provided with several rotating shafts, and described row is socketed in described rotating shaft Star gear, the end of the armature shaft are socketed with needle bearing, and the needle bearing is plugged on the middle axle position of even described fixed seat Put, the side face of the armature shaft is provided with gear part, and the flank of tooth in the gear part is meshed with described planetary gear, described Planetary gear is meshed with the internal tooth of the ring gear.

Described planetary gear material is powder metallurgy.

This structure of the present utility model, because afterbody of the carbon brush component installed in rotor is socketed in rotor with original surround Side face on compare, there is the effect for reducing volume, while the carbon brush on carbon brush component is pressed on the commutator segment of rotor afterbody, So that contact surface increases, the armature shaft torque of rotor is effectively increased so that the armature shaft on rotor is after gear reduction unit Torque is further increased, and will be exported in the torque transmission of the increase to isolator, so just reached torque greatly and had Effect reduces the technique effect of volume, so as to ensure that the clean boot of diesel engine, and extends engine life.

The utility model is further described with reference to the accompanying drawings and detailed description.

Brief description of the drawings

Fig. 1 is the structural representation of the utility model embodiment.

Embodiment

The utility model is specifically described below by embodiment, is served only for carrying out further the utility model Explanation, it is impossible to be interpreted as the restriction to scope of protection of the utility model.

As shown in figure 1, the utility model discloses a kind of star-like retarding starter of passenger car diesel, including housing 1, direct current Motor 2, isolator 3 and electromagnetic switch 4, direct current generator 2 and isolator 3 are arranged in the inner chamber of housing 1, and electromagnetic switch 4 is installed In the side of housing 1, wishbone lever 5 is provided between electromagnetic switch 4 and isolator 3, there is rotor 21 on direct current generator 2, determine Son 22 and carbon brush component 23, the afterbody of rotor 21 are provided with commutator 212, and the commutator segment 2121 of the commutator 212 is arranged on rotor On the end face of 21 afterbodys, carbon brush component 23 is arranged on the aperture position of housing 1 as end cap, has carbon brush in carbon brush component 23 231, carbon brush 231 is positioned axially and presses on the commutator segment 2121 of the tail end face of rotor 21, has armature shaft on rotor 21 213, gear reduction unit 6 is provided between armature shaft 213 and isolator 3.

Gear reduction unit 6 includes fixed seat 61, ring gear 62, drive shaft 63 and the planet being connected in the inner chamber of housing 1 Gear 64, fixed seat 61 are fixedly connected integrally with ring gear 62, and drive shaft 63 passes through fixed seat 61, and one end of drive shaft 63 is set There is terminal pad 631, terminal pad 631 is provided with several rotating shafts 632, and planetary gear 64, armature shaft 213 are socketed in rotating shaft 632 End be socketed with needle bearing 65, the needle bearing 65 is plugged on the location mid-shaft of fixed reservation 61, the side face of armature shaft 213 It is provided with gear part 2131, the flank of tooth in the gear part 2131 is meshed with planetary gear 64, planetary gear 64 and ring gear 62 Internal tooth be meshed.Keep on the same axis, protecting with drive shaft 63 by such armature shaft 213 of gear reduction unit 6 The torque of armature shaft 213 has been demonstrate,proved after planetary gear 64 and ring gear 62, has reached to slow down and improves the purpose of torque, so that driving The output torque of moving axis 63 effectively lifts and reached the demand for playing diesel engine.

The material of planetary gear 64 is powder metallurgy.Such stroke gear can in the process of running, the physical property of structure It is more reliable and more stable, so as to ensure that the reliability of starter.
