Abstract
The utility model relates to a gear shift stop gear of synchronous ware tooth cover belongs to the technical field that the derailleur designed, gear shift stop gear of synchronous ware tooth cover in concretely relates to manual gear shifting ware. The novel adoption limiting blocking piece structure of this implementation is assembled the separation blade on needs carry out spacing gear one side axle journal during the use, and the axial surely can by the fastening by other parts. After the gear shift of synchronous ware tooth cover, synchronous ware tooth cover spline terminal surface and limiting blocking piece end face contaction, it is spacing in order to realize. The utility model discloses a limiting blocking piece structure, simple structure, workable, convenient to use may not carry out special structural design and processing to the combination tooth of synchronous ware tooth cover, output shaft assembly after using this structure, be favorable to the universalization, and the thermal treatment degree of difficulty that has also reduced manufacturing procedure and combined the tooth has been solved simultaneously and has been divided the problem of casing because of the too big unable assembly of the combination tooth external diameter of output shaft assembly, and reasonable structure also is favorable to the lubricated demand of bearing.
Description
Technical field
The utility model belongs to the technical field of transmission design, is specifically related to the gearshift limit mechanism of synchronizer gear sleeve in a kind of manual transmission.
Background technique
In usual speed changer, the gearshift limit of synchronizer gear sleeve is by gear spoke end face, realizes tooth cover the spacing of end face in conjunction with tooth step surface, also have some speed changers by declutch shift shaft spacing or tooth cover internal spline not Equidep end face carry out spacing.
Above limit method is subject to the restriction of synchronizer size, outside diameter of gear size, selector device position and assembly relation on the one hand, also cause because part is more size accumulated tolerance large on the other hand thus affect efficiency, and complex structure causes operation to increase, technology difficulty strengthens, and causes this type of limit method cannot realize in some speed changer structure.
Summary of the invention
The purpose of this utility model is just for above-mentioned the deficiencies in the prior art, provides a kind of gearshift limit mechanism of novel synchronizer gear sleeve.
The purpose of this utility model is achieved through the following technical solutions:
The gearshift limit mechanism of synchronizer gear sleeve, comprise synchronizer gear sleeve 3, output shaft assembly in conjunction with tooth 4 and bearing 7, also comprise spacing catch 5, described spacing catch 5 external diameter be greater than output shaft assembly in conjunction with tooth 4 external diameter, but be less than bearing 7 external diameter, spacing catch 5 at output shaft assembly in conjunction with between tooth 4 and bearing 7, and with synchronizer gear sleeve 3, output shaft assembly arrange on the same axis in conjunction with tooth 4 and bearing 7, spacing catch 5 front end abutment is at the end face in conjunction with tooth 4 of output shaft assembly, and rear end is compressed vertically by bearing 7;
After synchronizer gear sleeve 3 gear shift, synchronizer gear sleeve 3 spline end face and spacing catch 5 end contact, spacing to realize.
Described spacing catch 5 is circular ring, and annulus end face side is provided with boss, and this raised head face abuts against on the end face of bearing 7.
Further, the periphery of described spacing catch 5 circle structure is designed to equally distributed rectangular paddle shape structure, to reduce spacing catch weight.
The utility model has the following advantages:
1) adopt limiting block chip architecture, structure simply, is easily processed.
2) easy to use, during use, limiting block sheet is assemblied in and needs to carry out on spacing gear one side shaft journal, be axially fixed by other part.
3) can not need after using this structure to synchronizer gear sleeve, output shaft assembly carry out specialized structure design and processing in conjunction with tooth, be conducive to generalization, decrease manufacturing procedure and in conjunction with the heat treatment difficulty of tooth.
4) due to the housing less to some bearing hole sizes be conducive to realize assembling and itself can not increase assembling difficulty, solve the problem that housing parts cannot assemble because of the excessive in conjunction with tooth external diameter of output shaft assembly, rational structure is also conducive to the lubrication needs of bearing simultaneously.
Accompanying drawing explanation
Fig. 1 a is the structural representation of spacing catch 5 in the gearshift limit mechanism of synchronizer;
Fig. 1 b is the side view of Fig. 1.
Fig. 2 is the assembling schematic diagram of the gearshift limit mechanism of synchronizer.
Wherein 1-input shaft, 2-synchronizer gear seat, 3-synchronizer gear sleeve, 4-output shaft assembly in conjunction with tooth, the spacing catch of 5-, 6-rear case, 7-bearing.
Embodiment
Below in conjunction with example, the utility model is described in further detail, but the utility model is not limited only to this.
The gearshift limit mechanism of synchronizer gear sleeve, comprise synchronizer gear sleeve 3, output shaft assembly in conjunction with tooth 4, bearing 7, also comprise spacing catch 5, described spacing catch 5 external diameter be greater than output shaft assembly in conjunction with tooth 4 external diameter, but be less than bearing 7 external diameter, spacing catch 5 at output shaft assembly in conjunction with between tooth 4 and bearing 7, and with synchronizer gear sleeve 3, output shaft assembly arrange on the same axis in conjunction with tooth 4 and bearing 7, spacing catch 5 front end abutment is at the end face in conjunction with tooth 4 of output shaft assembly, and rear end is compressed vertically by bearing 7;
During general assembly, for front and rear housings structure, output shaft assembly needs to pass from the bearing hole of housing 6 rear end, and is pressed in bearing hole by bearing 7;
During gear shift, when synchronizer gear sleeve 3 moving in conjunction with tooth 4 direction to output shaft assembly, after completing synchronizing process, synchronizer gear sleeve 3 and output shaft assembly continue mobile in conjunction with tooth 4 spline engagement, when the end contact of synchronizer gear sleeve 3 spline end face and spacing catch 5, synchronizer gear sleeve 3, in the axial direction by limited, can not continue mobile, now complete gear shift action.
