Abstract
The utility model relates to a reverse gear synchronizer, in particular to a reverse gear synchronizer of an automobile shifting transmission. The reverse gear synchronizer comprises an input shaft, wherein a five-shift synchronizer gear hub is sleeved on the input shaft; a synchronizer slide block is arranged in the five-shift synchronizer gear hub; a five-shift synchronizer gear sleeve is sleeved on the five-shift synchronizer gear hub; and a five-shift shifting fork is arranged on the five-shift synchronizer gear sleeve. The reverse gear synchronizer of the automobile shifting transmission enhances the operation property, is easy to machine, and reduces the production cost.
Description
Technical field
The utility model patent relates to a kind of synchronizer that reverses gear, and relates in particular to a kind of a kind of synchronizer that reverses gear of automobile gear shift speed changer.
Background technique
Present speed changer is not generally arranged the synchronizer that reverses gear owing to reasons such as structural configuration and costs, and the manual transmission of the synchronizer that do not reverse gear is hung and reversed gear than being easier under the situation that vehicle stationary and input shaft do not change.Reverse gear but often under the situation that input shaft does not stop operating fully, hang, can produce difficult extension of reversing gear, and in extension reverses gear process since reverse gear idle pulley and input shaft reverse gear fall mutual friction mutually between the wedge angle, the increment that wedge angle occurs falling weares and teares and is attended by the phenomenon of shriek.
Chinese patent CN200410054398.3, a kind of transmission reverse gear synchronizer that is used for the automobile mechanical field is disclosed, comprise: driving shaft five retaining gears, five retaining synchronizer gear sleeves, five retaining synchronizer key, five retaining synchronizer springs, the synchronizer that reverses gear draws circle, five retaining synchro converter rings, five retaining synchronization device cone rings, the synchronizer draw ring reverses gear, five retainings are in conjunction with ring gear, driving shaft five retaining gears combine ring gear by five retaining synchronizer gear sleeves with five retainings and are nested, and five retaining synchronizer key withstand on the five retaining synchronizer gear sleeves by five retaining synchronizer springs, five retaining synchronizer key draw circle and flexible synchronizer draw ring one end that reverses gear to join by the synchronizer that reverses gear, reverse gear the synchronizer draw ring the other end and five the retaining synchronization device cone rings nested, five the retaining synchro converter rings then sky be enclosed within five the retaining synchronization device cone rings on.This structure relative complex, and manufacture cost is higher relatively.
Summary of the invention
The utility model mainly is to solve the deficiencies in the prior art, a kind of solution difficult extension of reversing gear is provided, eliminate and hang in the process of reversing gear, the mutual fricative parts depreciation between the wedge angle of idle pulley and input shaft reverse gear and the problem of noise owing to reverse gear, and a kind of synchronizer that reverses gear that is used for the automobile gear shift speed changer is provided.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of synchronizer that reverses gear that is used for the automobile gear shift speed changer, comprise input shaft, be with five retaining synchromesh gear hubs on the input shaft, be provided with synchronizer key in the described five retaining synchromesh gear hubs, be with five retaining synchronizer gear sleeves on the described five retaining synchromesh gear hubs, described five retaining synchronizer teeth are provided with five retaining shift forks.
Its five retainings synchromesh gear hub is connected with the spline of input shaft, and five retaining synchronizer gear sleeves and five retaining synchromesh gear hubs rotate with input shaft by splined joint together jointly.Five retaining shift forks, one end is fixed on the five interior back fork axles of speed changer, can move axially gearshift along input shaft.Five the retaining synchronizer gear sleeves and five the retaining shift forks tapering is all arranged, by with five the retaining synchronizer gear sleeves rubbing action, reach the synchronous purpose of reversing gear.Earlier five retaining shift forks are firmly knocked in the five retaining synchronizer gear sleeves during installation, two conical surfaces fit tightly and certain interval are arranged.Again five retaining shift forks and five retaining synchronizer gear sleeves are inserted in the five retaining synchromesh gear hubs together.When extension reverses gear, five retaining shift forks move along the axial rear end toward speed changer of input shaft, at this moment because the strength that transmits on the strength of synchronizer key and the five back fork axle positioning seats makes two conical surfaces on five retaining shift forks and the five retaining synchronizer gear sleeves fit tightly the generation friction.Fix because of five retaining shift forks, logical these two mutual rubbing actions of the conical surface slow down until remaining static the input shaft rotating speed, and at this moment reverse gear idle pulley and input shaft reverse gear just engage smoothly, reverse gear and easily go into the position.
As preferably, described input shaft is provided with the input shaft spline, and described input shaft spline and five retaining synchromesh gear hubs match; Described five retaining synchromesh gear hubs are provided with tooth hub spline, and described tooth hub spline matches with five retaining synchronizer gear sleeves.
Therefore, the synchronizer that reverses gear that is used for the automobile gear shift speed changer of the present utility model improves operating characteristics, and easily processing reduces production costs.
