Description

A kind of diesel engine starting machine

The utility model relates to a kind of diesel engine starting machine.

Existing diesel engine starting machine, directly start as useful simple crank decompression on the diesel engines such as agricultural tricycle, not only spend all manpower, be difficult for starting, and the people is easily wounded in the crank startup, useful storage battery drives motor starting, because storage battery has acid solution to flow out contaminated environment, and period of service is short, the cost height, often maintenance is wasted time and energy.

The utility model overcomes above-mentioned shortcoming exactly, and a kind of diesel engine starting machine that starts by spring force is provided.

For finishing the purpose of this utility model, technical solution of the present utility model is: a kind of diesel engine starting machine, it comprises change speed gear box, centrifugal clutch, starting handle, actuator and brake, change speed gear box inside is distributed with four axles, four gears, on the I axle ordinary gear is installed, the II axle, on the III axle dual gear is installed, on the IV axle spline gear is installed, pinion on the gear of I axle and the II axle, pinion on big gear wheel on the II axle and the III axle, the spline gear engagement on big gear wheel on the III axle and the IV axle, the other end of IV axle and I axle has driving band or gear transmission; One shift fork is arranged on the spline gear on the IV axle, and the other end of shift fork is fixed on the pull bar, and pull bar passes through the speed change tank wall, and an end has a retracing spring, and the other end stretches in the actuator; Starting handle connects brake by starting pull bar, and brake then connects the III axle, and actuator comprises the stay cord of spring and spring, and stay cord is wrapped on the I axle; In the I axle couple axle is arranged, the inner ring of centrifugal clutch is enclosed within on the couple axle, and motion block is not fixed on the I axle.

Because the utility model has adopted such scheme, move starting handle, brake is unclamped, spring reset, suitable exoergic, the I axle rotates with stay cord, II axle, III axle rotate simultaneously, and the IV axle is motionless, after the I axle reaches certain speed, the interior axle of centrifugal clutch is that couple axle also changes starting with I axle one, couple axle connects the power pack section of diesel-powered vehicle, and diesel-powered vehicle promptly is activated like this, after diesel-powered vehicle starts, speed up, couple axle speed strengthens, and power-transfer clutch is owing to action of centrifugal force breaks away from, and suitable the putting of the spring potential energy of this moment finishes, stay cord on the I axle unclamps, and the I axle stops operating.The shift fork pull bar of this moment no longer is subjected to the effect of spring and resets, and spline gear resets, with the dual gear engagement on the III axle, because couple axle

Drive the IV axle and rotate, the III axle of this moment, II axle, I axle rotate with the IV axle, and stay cord twines to the I axle, stay cord pulling spring is run into the shift fork pull bar to the certain position spring, promote the shift fork pull bar, shift fork moves with pull bar, and shift fork is stirred spline gear and moved to the other end of IV axle, being out of gear on spline gear and the III axle, III, II, I axle stop operating, and starting handle resets simultaneously, checks the III axle, finish startup back starter motor and reset, car stops repeating when the back starts above process.The utility model has the following advantages compared with the prior art: (1) it need not oil, water not, not electricity consumption than durable with electro-motor economy, does not have any pollution to environment; (2) in light weight, volume is little, and is few with material, simple installation; (3) start soon, dependable performance can be finished the starting to the diesel engine three-wheel vehicle in 3 seconds, can not limited by landform in round-the-clock work down, and the life-span is long; (4) easy and simple to handle, need not reduce pressure, safe and reliable.

Below in conjunction with the drawings and specific embodiments in detail the utility model is described in detail:

Fig. 1 removes structural representation behind the gear shift cover for the utility model;

Fig. 2 is the mesh schematic representation of change speed gear box inner gear among Fig. 1;

Fig. 3 is the cross-sectional view of centrifugal clutch among Fig. 1;

Fig. 4 is the structural representation that starting handle starts pull bar and back connecting panel among Fig. 1;

Fig. 5 be among Fig. 1 before the structural representation of connecting panel and brake.

As Fig. 1, Fig. 2, Fig. 4, shown in Figure 5, the utility model comprises change speed gear box, centrifugal clutch 19, starting handle 1, actuator and brake, change speed gear box inside is distributed with four axles, four gears, ordinary gear 21 is installed on the I axle, be separately installed with dual gear 18 and 16 on II axle, the III axle, spline gear 23 is installed on the IV axle, couple axle 3 is arranged in the I axle, the pinion of gear 21 and gear 18, the pinion of the big gear wheel of gear 18 and gear 16, the big gear wheel of gear 16 and spline gear 23 engagements; The other end of IV axle and I axle is equipped with

chain pitch wheel

22 and 20 respectively, and the two is by chain 4 transmissions; Be installed with brake wheel 25 on the III axle; One shift fork 6 is arranged on the spline gear 23 on the IV axle, and shift fork 6 inserts in the groove of spline gear, and the other end of shift fork is fixed on the pull bar 5, and pull bar 5 passes through the speed change tank wall, and left end has a retracing spring 2, and right-hand member stretches in the shell 13 of spring; Start pull bar 8 and comprise U-shaped frame 32, spring 31, front and back connecting

panel

15 and 9, adapter shaft 10, brake comprises brake facing 16 and spring 14, starting handle 1 is fixed on the U-shaped frame 32 by steel rope, the other end of U-shaped frame connects back connecting panel 9 by damper spring 31 by iron 33, and back connecting panel 9 is fixed on the same adapter shaft 10 by screw 36 and 34 with preceding connecting panel 15.The other end of preceding connecting panel 15 is fixed on the speed change tank wall by spring 14, the centre is fixed with brake facing 17 by screw 35, brake facing 17 is checked the brake wheel 25 on the III axle, and when checking, spring is in compressive state, when moving starting handle forward, starting handle drives the back connecting panel and moves forward, and rotates thereby drive adapter shaft, and preceding connecting panel moves forward, be compressed spring and unclamp, brake facing unclamps the brake wheel on the III axle.Actuator comprises the steel rope 7 of spring 12 and spring left end, and steel rope 7 is wrapped on the I axle.Spring 12 is fixed in the spring shell 13, and spring shell 13 is fixed on the speed change tank wall by spiral nail 11, and the inner ring of centrifugal clutch 19 is enclosed within on the couple axle 3, not motion block by screw retention on the I axle.As shown in Figure 3, centrifugal clutch comprises and flies piece 28 and motion block 27 not, do not have mounting hole 26 on the motion block 27, fly in the wide arc groove 29 of the at one end narrow end of piece, flying piece one end is withstood by the pipe of interior band spring 30, when motion block not 27 rotates and interior axle when motionless, fly piece under the drive of motion block not to the narrow end of arc groove move to a certain degree be stuck in axle and motionless interblock, make axle rotation in motion block drives; When interior axle speed increases, when motion block speed does not reduce, fly piece and then move to the wide end of arc groove, thereby make not motion block and interior axle disengaging owing to action of centrifugal force, motion block does not rotate with interior axle.The groove that the little crank of one installation is arranged on the IV axle of the present utility model when using the utility model for the first time, needs shake the IV axle with little crank, so that steel rope twines the I axle, extension spring produces and stores potential energy, then startup automatically when using later on.
