Abstract
The utility model discloses a gearbox first gear and reverse gear synchronizer assembly, only a small part meshing when meshing with outer tooth cover for solving the synchronous tooth cover internal tooth that has gearbox first gear and reverse gear synchronizer assembly to exist, consequently, when the operation, easily cause the fender, influence driving safety's problem, the utility model discloses take skewed tooth (1) still are provided with recess (4) on being close to a terminal surface of outer tooth cover (3), and one big terminal surface (5) stretches into skewed tooth (1) recess (4) partly on the synchronous tooth cover (2) of being convenient for, prevents to take off the shelves.
Description
Technical Field
The utility model relates to a gearbox especially relates to a gearbox first gear and reverse gear synchronizer assembly of compriseing skewed tooth, outer tooth cover and synchronous tooth cover.
Background
At present, the market discloses such gearbox first gear and reverse gear synchronizer assembly, and its structural feature is: the synchronous gear sleeve is meshed with the other coaxial reversing gear, so that the purpose of realizing one gear and the reversing gear respectively is achieved.
Disclosure of Invention
The utility model aims at providing a gearbox first gear and reverse gear synchronizer assembly that is difficult for taking off the fender, can ensure driving safety.
In order to achieve the above object, the utility model discloses gearbox first gear and reverse gear synchronizer assembly, including skewed tooth, outer tooth cover and synchronous tooth cover, be connected with outer tooth cover on a skewed tooth terminal surface, it has synchronous tooth cover partly to mesh on outer tooth cover the skewed tooth still is provided with the recess on being close to a terminal surface of outer tooth cover, and the synchronous tooth of being convenient for sheathes in a big terminal surface and stretches into partly in the skewed tooth recess, prevents to take off the shelves.
The diameter of the groove is larger than or equal to the diameter of the large end face of the synchronous gear sleeve, and the axial depth of the groove is 0.25 mm.
After the structure is adopted, the groove is also arranged on the end surface of the helical tooth close to the outer gear sleeve, so that a large end surface of the synchronous gear sleeve can conveniently stretch into a part of the helical tooth groove, the meshing length of the outer gear sleeve and the synchronous gear sleeve is increased, and gear disengagement is prevented. Thereby achieving the purposes of being difficult to disengage and ensuring the driving safety.
Drawings
The present invention will be described in further detail with reference to the accompanying drawings and examples.
FIG. 1 is a schematic main sectional view of a first gear and a reverse gear synchronizer assembly of the transmission of the present invention.
Fig. 2 is an enlarged partial cross-sectional view of fig. 1.
In the figure: 1. helical teeth 2, synchronous gear sleeve 3, external gear sleeve 4, groove 5 and large end face.
Detailed Description
The first gear and reverse gear synchronizer assembly of the utility model shown in the attached figures 1 and 2 comprises a helical gear 1, an outer gear sleeve 3 and a synchronous gear sleeve 2, wherein the outer gear sleeve 3 is connected on one end surface of the helical gear 1, a part of the synchronous gear sleeve 2 is meshed on the outer gear sleeve 3, a groove 4 is also arranged on one end surface of the helical gear 1 close to the outer gear sleeve 3, which is convenient for a large end surface 5 on the synchronous gear sleeve 2 to extend into the groove 4 of the helical gear 1 for a part to prevent gear disengagement; the diameter of the groove 4 is larger than or equal to the diameter of the large end face 4 of the synchronous gear sleeve 2, and the axial depth of the groove is 0.25 mm.
Claims (2)
1. The utility model provides a gearbox first gear and reverse gear synchronizer assembly, includes skewed tooth, outer tooth cover and synchronous tooth cover, is connected with outer tooth cover on a skewed tooth terminal surface, and the meshing has a synchronous tooth cover partly on outer tooth cover, its characterized in that: a groove (4) is further formed in one end face, close to the outer gear sleeve (3), of the helical gear (1), and a large end face (5) on the synchronous gear sleeve (2) can stretch into one part of the groove (4) of the helical gear (1) conveniently to prevent gear disengagement.
2. The transmission first and reverse synchronizer assembly of claim 1, wherein: the diameter of the groove (4) is larger than or equal to the diameter of the large end face (5) of the synchronous gear sleeve (2), and the axial depth of the groove is 0.25 mm.
