Abstract
The utility model discloses a synchronizer of an automotive gear box, which comprises a synchronizer gear ring and a synchronizer spring. Positioning projections parallel to the center axis of the synchronizer spring are arranged at one end, which is close to the synchronizer gear ring, of the synchronizer spring, a plurality of positioning grooves matching with the positioning projections of the synchronizer spring are disposed on the outer wall of the synchronizer gear ring, and the positioning projections of the synchronizer spring match with the positioning grooves on the synchronizer gear ring so as to guarantee peripheral fixation of the synchronizer gear ring. The synchronizer of an automotive gear box is simple in structure and convenient in assembly, and bending ends match with the positioning grooves, thereby limiting degree of freedom in the periphery direction of the synchronizer gear ring, guaranteeing stability of the total synchronizer and increasing integral comfortableness of an automobile.
Description
Technical field
The utility model relates to gearbox manufacturing technology field, especially relates to a kind of automobile gearbox synchronizer.
Background technique
Gearbox uses more extensive in motor vehicle, and the synchronizer in the gearbox plays important effect.Because transmission input shaft and output shaft rotate with speed separately, the problem that has one " synchronously " during the conversion gear, two different gears of rotational speed mesh by force impact will inevitably take place, and damage gear, therefore, the gear shift of old-fashioned speed changer will be adopted the mode of " bipod clutch ", upgrading stops a moment at neutral position, and downshift will be at the neutral position open out, to reduce the speed discrepancy of gear, but this operates more complicated, is difficult to grasp accurately.Therefore the Designer creates " synchronizer ", will reach consistent rotating speed and engagement smoothly by meshed gears by synchronizer.
The general main synchronizer that comprises of synchronizer is in conjunction with parts such as toothed ring gear, synchro converter ring, synchronizer spring, synchromesh gear hub, synchronizer key and synchronizer gear sleeves in the automobile gearbox.
In most of vehicle traveling processes, when quickening for 3 or 4 grades, gearbox can send " rustling " abnormal sound, it is that 2 grades of synchro converter rings are not connected with synchronizer spring that abnormal sound produces reason, there is not restricting relation, cause 2 grades of synchro converter rings to be in free state, produce the vibrations noise, influenced the travelling comfort of automobile integral body.
Summary of the invention
The utility model provides a kind of automobile gearbox synchronizer simple in structure, and the assembling of this synchronizer is simple, avoids the vibrations that make progress in synchro converter ring week simultaneously, has reduced the noise that gearbox produces in the vehicle traveling process, has increased the travelling comfort of automobile integral body.
A kind of automobile gearbox synchronizer comprises synchro converter ring and synchronizer spring, and described synchronizer spring is provided with the positioning convex parallel with the central axis of synchronizer spring near an end end of synchro converter ring; Described synchro converter ring outer wall is provided with some locating slots that match with the positioning convex of synchronizer spring, and the positioning convex of synchronizer spring matches with locating slot on the synchro converter ring and guarantees that synchro converter ring is circumferentially fixing.
For ease of assembling, can be chosen in one or more locating slots are set on the synchro converter ring, the quantity of the general locating slot of using always is 1～5, locating slot is generally selected cylinder shape groove.For processing and locating slot easy to assembly can be evenly arranged in synchro converter ring around, also can adopt other modes to arrange.The degree of depth of locating slot and internal diameter size need match with the length of the positioning convex of synchronizer spring one end and external diameter or width, are generally little Spielpassung, and the gap is unsuitable excessive, the excessive stability that is unfavorable on the synchro converter ring circumferencial direction.
Can select positioning convex and synchronizer spring for being wholely set for ease of processing, vertically be bent to form by the end end of synchronizer spring near synchro converter ring, the length of bending end is generally 2.5～3.5mm, the degree of depth of locating slot is 3.0～4.0mm on the synchro converter ring, guarantee the outside dimensions of the internal diameter of locating slot greater than synchronizer spring end positioning convex simultaneously, the degree of depth is greater than the length of the bending end of synchronizer spring.
During automobile gearbox synchronizer practical set of the present utility model, only need bending end with synchronizer spring be inserted in the locating slot close on the synchro converter ring and get final product, easy to assembly.
Automobile gearbox synchronizer of the present utility model, simple in structure, be convenient to assembling, positioning convex and locating slot cooperatively interact, and have limited the degrees of freedom on the synchro converter ring circumferencial direction, have guaranteed the stability of whole synchronizer, have increased the travelling comfort of automobile integral body.

Embodiment
Shown in Fig. 1～6, a kind of automobile gearbox synchronizer comprises synchro converter ring 1 and synchronizer spring 3, and synchronizer spring 3 one end ends are the positioning convex 4 that be arranged in parallel with synchronizer spring 3 central axis; Synchro converter ring 1 outer wall is provided with 3 locating slots 2 that match with the positioning convex 4 of synchronizer spring 3, and the positioning convex 4 of synchronizer spring 3 matches with locating slot 2 on the synchro converter ring 1 and guarantees that synchro converter ring 1 is circumferentially fixing.
As shown in Figure 1, automobile gearbox mainly comprises main shaft 5, is set in synchronizer spring 3 on the main shaft 5, synchro converter ring 1, second gear in conjunction with toothed ring gear 6,1/2 synchromesh gear hub, 7,1/2 synchronizer key 8 and 1/2 synchronizer gear sleeve 9 etc.; Synchronizer spring 3 is a synchronizer second gear spring among Fig. 1, and synchro converter ring 1 is the second gear ring gear.
The quantity of locating slot 2 is 1～5 on the synchro converter ring 1, be cylinder shape groove, can select other shapes according to actual needs, locating slot 2 quantity are three among Fig. 6, be evenly arranged in around the synchro converter ring 1, between angle be 120 the degree, the arrangement of locating slot 2 also can be adjusted according to actual needs.
The positioning convex 4 that can select synchronizer spring 3 for ease of processing and synchronizer spring 3 are for being wholely set, vertically be bent to form by an end end near synchro converter ring 1, length for ease of the assembling bending end is 2.5～3.5mm, the degree of depth of locating slot 2 is 3.0～4.0mm on the synchro converter ring 1, guarantee the outside dimensions of the internal diameter of locating slot greater than the synchronizer spring bending end simultaneously, the degree of depth is greater than the length of the bending end of synchronizer spring.
