Description

The laborsaving starter of automobile and tractor multifunctional safe

The utility model belongs to vehicle and manually boots instrument.

In communications and transportation, automobile, tractor owning amount are doubled and redoubled at present, still have some vehicles to need start-up by hand in some outmoded vehicles, the special north in the winter time, during no storage battery, vehicle launch is difficulty on the car, generally adopts simple tools---crank, manual cranking, advantage is that structure is very simple, but its deficiency is an effort, and counter-rotating rapidly takes place in the process of shaking sometimes, abnormally dangerous, make troubles to vehicle launch.

For solving the deficiency of above crank, the purpose of this utility model provides a kind of automobile, the laborsaving starter of tractor multifunctional safe, is added with mechanical transmission in the middle of starter, to reach laborsaving, safe, multi-functional purpose.

The structure of the utility model is illustrated in conjunction with the embodiments:

Fig. 1 is the laborsaving starter structure principle chart of automobile, tractor multifunctional safe;

Fig. 2 is the laborsaving starter shape assumption diagram of automobile, tractor multifunctional safe;

Fig. 3 is automobile, the laborsaving starter overload clutch of tractor multifunctional safe structural drawing;

Fig. 4 is automobile, the laborsaving starter tooth of tractor multifunctional safe wedge structural drawing;

Fig. 5 is automobile, the laborsaving starter of the tractor multifunctional safe outlet structure figure that pulls pin.Its structural design is achieved in that the starting bar of its structure of this starter by front end, the crank crank of rear end band six side's plugs, and middle outside is a housing, and the overload protection clutch mechanism is housed in the housing; Reduction gears mechanism and unidirectional operation mechanism form, and shell is provided with lock pawl.(as shown in Figure 1); detailed structure is to connect starting bar 2 for finger 1 before the starter; the outside is a shell 3; starting bar 2 outsides are with overload clutch stator 4; axial clearance spacer 5 is equipped with in stator 4 the insides; adjust screw 6; many group springs 7; steel ball 8; packing ring 9; back-up ring 10 and exteranl gear 11 (internal gear) have been formed the overload clutch protection mechanism; excellent gear 21 is housed in exteranl gear 11 (internal gear); rod gear 21 meshes with the part external tooth in internal gear 11; formed reducing gear therefrom; for preventing the operating stem counter-rotating; exteranl gear 11; rod gear 21 and stopper spring pin 13; locating stud 26; jump ring 27; pressing plate 28; spring 29; tooth wedge 30 has been formed unidirectional operation mechanism; starter frame 3 is provided with in the startup hole of bumper 33 that lock pawl (or stop pin) inserts lock pawl in automobile or tractor; stop bracket 32 is housed in the hole starter frame and car body are become one, form stop mechanism.At excellent gear 21 two ends bearing 12 and 18 are housed, locating pin 14 is equipped with in the outside is fixed as one rotor housing 3 and stator case 16,17 and 19 is outer washer in the outer bearing, six side's plugs of follower head insert in the excellent gear and are connected with gear, the back is fixing with crank crank 22 by fastening cap 20, on crank, be provided with crank spring 23, ejector pin 24 and sleeve 25.Six side's plugs of the starting bar of starter front and back and crank crank can arbitrarily insert, transfer to from starter, also this two part directly can be inserted to become common crank.

When using this device, at first in the starting hole of the bumper of starting lever insertion automobile, the finger on the starting lever and the starting dog of motor are combined, and then the lock pawl (or stop pin) of starter is inserted in the starting hole of bumper of automobile (or insertion is equipped with in the hole of thrust frame of thrust holder) shell of starter and car are become one, when shaking hand-crank 22, spillikin gear 21 just drives overload clutch rotor internal gear 11 and rotates, rotor moving steel ball 8 of 11 generations rotates with rotor 11, overload clutch stator 4 rotates thereupon under the drive of steel ball, also just drive starting lever 2 actions, starting lever 2 is stirred the engine start pawl and is started, when meshing running clockwise, at this moment interior external gear pushes tooth wedge 30 to little spring 29, make little spring 29 compressions push spring pin 13 to, reducing gear is run well.

When anti-electricity takes place when (when producing counter-rotating) starting lever with the starting dog of motor round about speed race moving; at this moment starting lever drives overload clutch stator 4; action round about; at this moment the housing of starter is fixed with car body under the effect of lock pawl 3; overload clutch exteranl gear 11 also drives excellent gear 21 counter-rotatings thereupon; in the moment of this counter-rotating; the angle of external gear pump blocked inside and outside gear meshing action immediately in the tooth wedge 30 of unidirectional works pushed rapidly under the effect of little spring; crank handle is fixed can not reverse thereupon; the stator 4 of overload protection clutches has overcome the friction pressure of steel ball 8 at this moment; steel ball 8 is return spring 7 compressions in the steel ball hole of the rotor 11 of overload clutch; with stator 4 counter-rotatings, guaranteed the safety of starting.

The advantage of the utility model: starter is equipped with retarder, and is laborsaving, and converse stopping mechanism is housed simultaneously, safe and reliable during use, can make common crank and use, and can make the hexagonal spanner again, easy to install, is adapted at using on various automobiles or the tractor.
