Description
Technical field
The present invention relates to a kind of reverse gear gearshift mechanism that is used for the automobile mechanical field, specifically is a kind of speed variator reverse gear synchronizer.
Background technique
General speed variator reverse gear adopts the method for slip reverse idler gear to change reverse gear, this be a kind of application for many years and ripe tradition change the method for reverse gear.But because the surface friction drag of its reverse gear gearshift mechanism (resistance that comprises automobile operation mechanism) is bigger, when adding gear shift asynchronous make reverse gear in conjunction with the time the making a concerted effort of the resistance that produces, making has two catcher senses or not in place when changing reverse gear.Therefore step on clutch at vehicle stop state (during neutral gear) and need just can change to reverse gear through about about 4 seconds time (allowing the speed drop of driving shaft and clutch friction plate get off back), change reverse gear behind the clutch immediately and also make the gear shift difficulty if step in running owing to transmission drive shaft and clutch friction plate, send sometimes and beat tooth sound, cause reverse gear to damage easily.Be to improve the reverse gear shift property of speed changer, the speed drop that will work as when stepping on clutch and will change reverse gear fast transmission drive shaft and clutch friction plate gets off.The present invention uses former speed changer Five-gear synchronizer assembly, will be decomposed into two parts in conjunction with ring gear, one be in conjunction with ring gear, another is conical ring, makes speed discrepancy reduce to minimum, makes things convenient for entering of reverse gear.
Find that by literature search the patent No. is: ZL00251763.9, denomination of invention is: " transmission for vehicles reverse gear half synchromesh gear ", this patent relates to the improvement to the reverse gear structure, but has influenced the intensity of reverse gear shaft.
Summary of the invention
The present invention is directed to the deficiencies in the prior art and defective, a kind of speed variator reverse gear synchronizer is provided, by being decomposed in conjunction with ring gear and conical ring in conjunction with ring gear, the speed drop of driving shaft and clutch friction plate is got off, thereby change to reverse gear easily, solve that method that general speed variator reverse gear adopts the slip reverse idler gear is changed reverse gear and the surface friction drag of its mechanism of existing is big, frequent problem not in place during reverse gear.
The present invention is achieved by the following technical solutions, the present invention includes: five grades of gears of driving shaft, Five-gear synchronizer tooth cover, Five-gear synchronizer slide block, Five-gear synchronizer spring, reverse gear synchronizer draw circle, Five-gear synchronizer ring gear, Five-gear synchronizer conical ring, reverse gear synchronizer draw ring, five-gear combinating tooth ring.Its annexation is: five grades of gears of driving shaft are nested with five-gear combinating tooth ring by Five-gear synchronizer tooth cover, and withstanding on the Five-gear synchronizer tooth by the Five-gear synchronizer spring, the Five-gear synchronizer slide block puts, the Five-gear synchronizer slide block draws circle and flexible reverse gear synchronizer draw ring one end to join by the reverse gear synchronizer, the other end of reverse gear synchronizer draw ring is nested with the Five-gear synchronizer conical ring, just can drive the Five-gear synchronizer conical ring when Five-gear synchronizer tooth cover drives the Five-gear synchronizer slide block thus, Five-gear synchronizer ring gear then sky is enclosed within on the Five-gear synchronizer conical ring.
When Five-gear synchronizer tooth cover is moved to the left when entering reverse gear, driving the Five-gear synchronizer slide block also moves left, therefore make reverse gear synchronizer draw ring pulling Five-gear synchronizer conical ring to left movement, the Five-gear synchronizer conical ring is combined with the conical surface of Five-gear synchronizer ring gear, increased the frictional force between them, thereby the reduction speed drive shaft makes things convenient for entering of reverse gear.When Five-gear synchronizer tooth cover moves right when entering five grades, driving the Five-gear synchronizer slide block also moves right, the conical surface that makes the Five-gear synchronizer slide block push away the Five-gear synchronizer ring gear combines with the Five-gear synchronizer conical ring to the right, Five-gear synchronizer tooth cover is pressed to the Five-gear synchronizer ring gear simultaneously, make five grades of driving tooths close, change to five grades with the driving shaft rotating speed.
The present invention does not change the structure space of existing speed changer too many part not being changed yet, and has reduced the cost and risk of changing.The present invention improves a lot to the shift property of speed variator reverse gear, and middle phenomenon of stopping takes an evident turn for the better during the exchange reverse gear, and reverse gear is more convenient to make the damage of reverse gear obtain very big improvement thereby change.

Embodiment
As shown in Figure 1, the present invention includes: five grades of gears 1 of driving shaft, Five-gear synchronizer tooth cover 2, Five-gear synchronizer slide block 3, Five-gear synchronizer spring 4, reverse gear synchronizer draw circle 5, Five-gear synchronizer ring gear 6, Five-gear synchronizer conical ring 7, reverse gear synchronizer draw ring 8, five-gear combinating tooth ring 9.Its Placement is: five grades of gears 1 of driving shaft are nested with five-gear combinating tooth ring 9 by Five-gear synchronizer tooth cover 2, and Five-gear synchronizer slide block 3 withstands on the Five-gear synchronizer tooth cover 2 by Five-gear synchronizer spring 4, Five-gear synchronizer slide block 3 draws circle 5 and flexible reverse gear synchronizer draw ring 8 one ends to join by the reverse gear synchronizer, and the other end of reverse gear synchronizer draw ring 8 is nested with Five-gear synchronizer conical ring 7.Just can drive Five-gear synchronizer conical ring 7 when Five-gear synchronizer tooth cover 2 drives Five-gear synchronizer slide block 3 thus, Five-gear synchronizer ring gear 6 then sky is enclosed within on the Five-gear synchronizer conical ring 7.
When Five-gear synchronizer tooth cover 2 is moved to the left when entering reverse gear, driving Five-gear synchronizer slide block 3 also is moved to the left, therefore make reverse gear synchronizer draw ring 8 pulling Five-gear synchronizer conical rings 7 to left movement, Five-gear synchronizer conical ring 7 is combined with the conical surface of Five-gear synchronizer ring gear 6, increased the frictional force between them, thereby the reduction speed drive shaft makes things convenient for entering of reverse gear.When Five-gear synchronizer tooth cover 2 moves right when entering five grades, driving Five-gear synchronizer slide block 3 also moves right, the conical surface that makes Five-gear synchronizer slide block 3 push away Five-gear synchronizer ring gear 6 to the right combines with Five-gear synchronizer conical ring 7, Five-gear synchronizer tooth cover 2 is pressed to Five-gear synchronizer ring gear 6 simultaneously, make driving shaft five grades of teeth 1 close, change to five grades with the driving shaft rotating speed.
