Abstract
The utility model discloses an integrally formed beach vehicle gear-shifting driven gear which comprises a gear-shifting cam, wherein the outer edge of the gear-shifting cam is provided with a plurality of gear limiting grooves, one side of the gear-shifting cam is provided with a driving gear, the center of the gear-shifting cam is provided with a D-shaped hole penetrating through the center of the driving gear, the other side of the gear-shifting cam is provided with a shaft shoulder, and the gear-shifting cam, the driving gear and the shaft shoulder are of an integral structure taking powder metallurgy as a main body. The output adopts an integral structure, and is formed by one-time pressing by using a powder metallurgy technology, so that the production cost is reduced, and the structural strength of a product is improved.
Description
Technical Field
The utility model relates to the field of motor vehicle gear shifting devices, in particular to an integrally formed beach vehicle gear shifting driven gear.
Background
The engine gear shifting cam of the dune buggy is used for shifting the dune buggy, a gear shifting mechanism of the dune buggy generally assembles a driving gear and a gear shifting cam together, and the driving gear drives the gear shifting cam to realize the gear shifting operation; the second is to produce the gear shifting cam and the driving gear respectively, and then press and combine the two parts together, and by adopting the two modes, the structural strength of the joint is lower, the fracture is easy, the defective rate of products is high, and meanwhile, the production process is complex, the production steps are multiple, the cost is higher, and the production efficiency is low.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide an integrally formed beach vehicle gear-shifting driven gear, which improves the structural strength of products and reduces the production cost.
In order to achieve the purpose, the utility model provides the following technical scheme:
the utility model provides an integrated into one piece's sandy beach car driven gear that shifts, is provided with a plurality of gear spacing grooves including the cam of shifting, the outer fringe of the cam of shifting, it is provided with drive gear to shift cam one side, and the cam center of shifting is seted up the D shape hole that runs through drive gear center, and the cam opposite side of shifting is provided with the shaft shoulder, cam, drive gear and shaft shoulder of shifting are with powder metallurgy as the body structure of main part. The powder metallurgy technology is adopted, the integral forming manufacturing is realized, the production process steps are reduced, the production efficiency is improved, and meanwhile, the structural strength of the product is enhanced.
Preferably, the number of the gear limiting grooves is 5. The gear shifting mechanism is suitable for shifting 5 gears of the beach vehicle back and forth.
Preferably, the driving gear is an involute gear. The involute gear has the advantages of stable transmission, small vibration and constant and non-fluctuating output rotating speed, and the center distance of two wheels allows certain installation error, thereby not causing the fluctuation of the output rotating speed.
Preferably, the roots of the driving gears are in round corner transition.
Preferably, the number of teeth of the driving gear is 17.
Compared with the prior art, the utility model has the following advantages:
the utility model adopts an integrally formed production process, the gear shifting cam and the driving gear are manufactured into an integral structure, the powder metallurgy technology is adopted, the preparation procedures are reduced, the manufacturing cost is reduced, the product precision is unified, the structural strength of the product is improved by one-step forming, and the gear shifting gear is not easy to break in the gear shifting motion.

FIG. 1 is a schematic structural view of the present invention;
FIG. 2 is a cross-sectional view of FIG. 1A-A;
FIG. 3 is a perspective view of the present invention;
wherein, 1-gear shifting cam, 101-gear position limiting groove, 2-driving gear, 3-shaft shoulder and 4-D-shaped hole
Detailed Description
The following detailed description of the present invention will be further illustrated with reference to the accompanying drawings and detailed description, it is to be understood that these embodiments are merely illustrative of the present invention and are not intended to limit the scope of the present invention, and that various equivalent modifications thereof can be made by those skilled in the art without inventive faculty after reading the present invention, which fall within the scope of the appended claims of the present application.
As shown in fig. 1-3, an integrated into one piece's sandy beach car driven gear that shifts, including the cam of shifting, the outer fringe of the cam of shifting is provided with 5 gear spacing grooves, 5 gears that are applicable to sandy beach car make a round trip to switch, cam one side of shifting is provided with drive gear, drive gear adopts involute gear, the vibration is little, the transmission is more steady, make shifting of sandy beach car more smooth and easy, shift cam center and set up the D shape hole that runs through drive gear center, the cam opposite side of shifting is provided with the shaft shoulder, the cam of shifting, drive gear and shaft shoulder adopt powder metallurgy technique, integrated into one piece suppression forms, need not through a plurality of complicated processes, the production efficiency is improved, the manufacturing cost is reduced, structural strength to work piece itself has very big improvement, the qualification rate of product manufacturing is improved.
The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and substitutions can be made without departing from the technical principle of the present invention, and these modifications and substitutions should also be regarded as the protection scope of the present invention.
