Description

The pedal starting device

The utility model relates to a kind of pedal starting device of adorning usefulness on diesel engine.

The starting form of using on the diesel engine mostly is shaking type at present, minority electric motor starting formula is also arranged, the spiral spring priming type, as the hand starting formula is to be inserted by a crooked crank to shake in the hole, the quick turn crank of exerting oneself, this starting is required great effort very much, and is also dangerous, sometimes also need bend over to shake, more inconvenient; Adopt electric motor starting, the cost height, limited and electric power of the storage battery life-span of using as power supply is prone to deficiency, and functional reliability is low, is difficult to penetration and promotion, and the starting of spiral spring formula needs join together with diesel engine, inconvenience and cost height is installed, unfavorable applying.

The purpose of this utility model just provides a kind of novel pedal starting device, to solve the diesel engine starting inconvenience, especially starts the problem of effort especially winter.

The purpose of this utility model is achieved like this, at lower box stationary axle is housed, its axle is gone up foot-operated knee of dress and spacing torsion spring, driving shaft is equipped with on casing top, driving gear and directional clutch (as the override type ratchet mechanism) are arranged on it, eccentric wheel is housed on the directional clutch, on the foot-operated knee hinge is housed, link to each other with eccentric wheel by connecting rod, on casing, the idle gear that is meshed with driving gear is housed through idler shaft, idle gear is meshed with the starting gear of adorning mutually through starting shaft, and steel ball and retaining spring are housed on the starting shaft, and starting dog is arranged on the starting shaft.

The utility model novel structure uniqueness, easy to use, starting is quick, and safety is laborsaving, is convenient to install, reliable operation, durable in use, cost is low, is easy to produce and popularization and application, has good economic and social benefit.

Below in conjunction with accompanying drawing structure of the present utility model is elaborated.

Fig. 1 is a structural front view of the present utility model.

Provide by Fig. 1, the utility model is by casing, driving mechanism, foot-operated knee and drawstring constitute, stationary axle 2 is equipped with in casing 1 bottom, spacing torsion spring 3 and foot-operated knee 4 are housed on the stationary axle 2, drawstring 9 is equipped with in foot-operated knee 4 ends, driving shaft 21 is equipped with through bearing in casing top, driving gear 11 and directional clutch 10 are housed on the driving shaft 21, eccentric wheel 7 is housed on the directional clutch 10, hinge 8 is housed on the eccentric wheel 7, on the foot-operated knee 4 hinge 5 is arranged, be contained in through connecting rod 6 on the hinge 8 of eccentric wheel 7, on the idler shaft 12 that is equipped with in the casing 1 idle gear 13 is housed, idle gear 13 is meshed with driving gear 11, is meshed with starting gear 20 on the slippage starting shaft 18 that is contained in through bearing on the casing again, an end is equipped with starting dog 19 on the starting shaft 18, the other end is equipped with flywheel 22 and straight pin 17, and locking ball 16 is housed on the annular groove of starting shaft 18, stage clip 15 and slack adjuster 14 fill lubricant oil in the casing 1.Wherein, foot-operated knee 4, connecting rod 6, axle 21 arrive a crank and 21 frame to 2 on axle of 8 on axle, formation fourbar linkage; Driving gear 11, idle gear 13 and starting gear 20 constitute gear.

It is pointed out that in case of necessity driving gear 11 can directly be meshed with starting gear 20, saves idle pulley.As the starting shaft of diesel engine using band straight pin, the starting shaft 18 of starter is adorned the straight pin ends, then can adorn with starting dog to connect with it.

Use condition of the present utility model is, starter is contained on the foot rest of diesel engine starting pawl side, starting shaft 18 axis and the diesel engine starting pawl axis of starter align, and make starting shaft 18 and diesel engine starting pawl end face keep suitable distance, at this moment, the steel ball location that slippage starting shaft 18 is slipped in the starting shaft annular groove is in retracted mode, when diesel engine need start, promote and rotate (being generally clockwise) to be contained in the starting dog 19 on the starting shaft 18, move on the steel ball 16, starting shaft 18, axle head enters the diesel engine starting pawl, straight pin 17 screws with it on the axle, steel ball 16 enters locking starting shaft 18 in another limited ring groove of starting shaft 18 under stage clip 15 pushing, actuating is connected to the diesel engine reduction valve handle of position easy to operate, pin is put in the drawstring 9, firmly pedal downwards, the connecting rod 6 that foot-operated knee 4 pullings are hinged, drive the eccentric wheel 7 that is hinged with it successively, directional clutch 10, starting shaft 21, starting gear 11, idle gear 13, starting gear 20, starting shaft 18 and on flywheel 22, straight pin 17 rotates, straight pin 17 drives joining diesel engine starting pawl and rotates, the big flywheel of diesel engine also rotates, when foot-operated knee 4 walks to the limit inferior position, straight pin 17 on the starting shaft 18 under 22 inertial force of the flywheel on the axle drive with diesel engine starting pawl close-coupled, directed clutch 10 is in separated state, lift lift belt 9 on the pin, when foot-operated knee 4 reaches the limes superiors position, step on foot-operated knee 4 firmly, pedal so continuously, diesel engine promptly reaches starting speed, unclamp diesel engine reduction valve handle, diesel engine starting, straight pin 17 on the starting shaft 18 is under flywheel 22 inertial force effects at this moment, released by diesel engine starting pawl end chamfer, steel ball 16 slips into locking in starting shaft 18 annular grooves, starting shaft 18 recovers separated state with the diesel engine starting pawl, foot-operated knee 4 recovers former qualification position under the effect of spacing torsion spring 3, finish the diesel engine starting overall process.Should be noted that, in case of necessity starting shaft 18 is inserted in the diesel engine starting pawl, shake starter starting dog 19, also can realize the shaking type starting with handle.The utility model starting is fast, and is safe and reliable, laborsaving saving time, and it is applied and must make positive contribution for society.
