Abstract
The utility model relates to a timing chain tensioner of a vertical electrical starting engine of a motorcycle, which comprises a tensioner body (3). The timing chain tensioner of a vertical electrical starting engine of a motorcycle is characterized in that a rack push rod (5), a tension spring (4), and a screw bolt (1) are connected in series and arranged in the tensioner body (3). A ratchet pawl (8), a cylindrical pin (7), and a ratchet pawl spring (6) are correspondingly arranged on one side of the rack push rod (5). Due to the fact that the principle of a ratchet mechanism is adopted by the timing chain tensioner of a vertical electrical starting engine of a motorcycle, therefore, the purpose that the rack push rod only can advance and can not retract is achieved. The timing chain tensioner of a vertical electrical starting engine of a motorcycle can not generate the problems that the fatigue and the break of parts and components are generated and caused due to the running fluctuation of a timing chain when the rotary speed of an engine is unstable. In a word, the timing chain tensioner of a vertical electrical starting engine of a motorcycle has simple structure and good use effect. The timing chain tensioner of a vertical electrical starting engine of a motorcycle is particularly suitable for a vertical electrical starting engine with 125CC-150CC discharge capacity.
Description
Technical field
The utility model relates to a kind of timing chain stretcher of motorcycle engine chain tensioning device, particularly a kind of vertical electric ato unit.
Background technique
At present, known vertical electric ato unit timing chain stretcher is to be linked to each other and be assembled by stretcher head, location end cap, screw rod, nut, lining, plain washer, plane scroll spring, tensioner body, stretcher key.After the stretcher of this spline structure loaded onto motor and take out key, screw rod is rotating nut under the effect of plane scroll spring elastic force, promotes the stretcher head and holds out against the chain tension plate, makes chain tension; When chain elongated, the automatic feed under the effect of spring force of stretcher head held out against the chain tension plate and tension chain all the time.But, because engine speed changes often, make the timing chain running produce fluctuation, and the self-locking and produce play more fully of the helical pitch of screw rod, nut, make plane scroll spring and screw rod connecting end bear stress alternation and produce the fatigue break problem, cause that stretcher lost efficacy.
Summary of the invention
In order to overcome the easily broken problem of existing timing chain stretcher plane scroll spring, the utility model provide a kind of simple in structure, using effect is good, the engine chain stretcher of self-locking fully.
The utility model is achieved in that a kind of engine chain stretcher, comprises tensioner body, it is characterized in that: polyphone is provided with tooth bar push rod, tension spring, bolt in the described tensioner body; Side correspondence at the tooth bar push rod is provided with ratchet, pin, click spring.
The utility model is owing to adopted the principle of ratchet mechanism, so can reaching, the tooth bar push rod can only advance, the purpose that can not retreat, and the utility model can not produce because of engine speed when unstable timing chain running fluctuation produce the problem that causes the component fatigue break.In a word, the utility model is simple in structure, and using effect is good, is specially adapted to the vertical electric ato unit of 125CC-150CC discharge capacity.

Embodiment
Referring to accompanying drawing as can be known: a kind of engine chain stretcher, comprise tensioner body 3, it is characterized in that: polyphone is provided with tooth bar push rod 5, tension spring 4, bolt 1 in the described tensioner body 3; Side correspondence at tooth bar push rod 5 is provided with ratchet 8, pin 7, click spring 6.
Above-mentioned bolt 1 is provided with seal ring 2.
In this example, tension spring 4 is a cylindrical spring, is built in the tooth bar push rod 5; Pin 7 is a straight pin.
Claims (4)
1, a kind of engine chain stretcher comprises tensioner body (3), it is characterized in that: polyphone is provided with tooth bar push rod (5), tension spring (4), bolt (1) in the described tensioner body (3); Side correspondence at tooth bar push rod (5) is provided with ratchet (8), pin (7), click spring (6).
2, engine chain stretcher as claimed in claim 1 is characterized in that: described bolt (1) is provided with seal ring (2).
3, engine chain stretcher as claimed in claim 1 is characterized in that: described tension spring (4) is a cylindrical spring; Described pin (7) is a straight pin.
4, as claim 1,3 described engine chain stretchers, it is characterized in that: described tension spring (4) is for being built in the described tooth bar push rod (5).
