Abstract
The utility model discloses an integrated structure of an output shaft and shifting gears of an automobile gearbox, which comprises the output shaft. The integrated structure is characterized in that: a small shifting gear and a large shifting gear are arranged at one end of the output shaft; and the small shifting gear, the large shifting gear and the output shaft adopt the integrated structure to form a whole. In the integrated structure, the output shaft and the two shifting gears are manufactured into a whole by means of forging, and such working procedures as mechanical processing and welding of rolling teeth and inserting teeth, so that the manufacturing and processing efficiency is obviously increased, and the manufacturing cost is reduced; the overall intensity and precision are improved, and the technical process is shortened; the disadvantages of insufficient welding, loose welding, non-firm welding and the like cannot be caused; the smooth power transmission, stable gear shifting and safe running of an automobile are ensured; the gear shifting operation is flexible and convenient, the comfort degree is raised, and the service life is prolonged.
Description
Technical field
The utility model relates to a kind of output shaft and power shift gear of automobile gearbox output shaft structure, especially automobile gearbox and makes the all-in-one-piece integral structure.
Background technique
Automobile gearbox output shaft and power shift gear thereof play gearshift and driving force effect, safety traffic for automobile is extremely important, it is an important breaking piece on the automobile, directly influence carrying out smoothly of the transmission of power of automobile, steady gearshift, support vehicles safety traffic tool is played a very important role.Because traditional machine cut processing mode can only be processed output shaft and gearshift gear ring (gear) separated into two parts separately, output shaft and the gearshift gear ring that is up to the standards is welded together again; Otherwise when the gearshift gear ring is carried out gear hobbing and gear shaping machining, will interfere, can't carry out machining the gearshift gear ring.Traditional carries out gear hobbing and gear shaping machinery processing mode to the gearshift gear ring, and work efficiency is lower, and is easy to generate waster, the corresponding fabrication and processing cost that increased; Subsequently with output shaft and gearshift gear ring welding process in, cause defectives such as weldering is taken off, rosin joint easily, form not prison welding, make automobile in long-term subsequently using process, there is more serious potential safety hazard, even cause the generation of automotive safety accident, driver and passenger's the person and property caused great infringement.And when welding, the welding heat distortion is generally all bigger, also can reduce the precision of gear greatly, reduces the stationarity of transmission of power and gearshift, and flexibility, the travelling comfort of automobile gear shift are brought influence.
Summary of the invention
The utility model at the output shaft and the power shift gear separated into two parts of prior art process separately, weld together again existing work efficiency lower, be easy to generate waster, the thermal distortion of when welding reduces deficiencies such as the precision of gear, the stationarity that reduces transmission of power and gearshift, the flexibility that reduces automobile gear shift and travelling comfort more greatly, greatly, and the integral structure of a kind of output shaft and power shift gear making all-in-one-piece automobile gearbox output shaft and power shift gear is provided.
The technical solution of the utility model: the integral structure of automobile gearbox output shaft and power shift gear, comprise output shaft, it is characterized in that: at an end of output shaft, be provided with gearshift small gear and gearshift gearwheel, described gearshift small gear, gearshift gearwheel and output shaft are integral structures, become as a whole.
Further feature is: the diameter of gearshift gearwheel is greater than the diameter of gearshift small gear.
The gearshift small gear is near the end of output shaft.
The integral structure of the utility model automobile gearbox output shaft and power shift gear has following characteristics:
1, output shaft and power shift gear are made into one, make by the forging mode, omit gear hobbing and operations such as gear shaping machining, welding, significantly improve manufacturing, work efficiency, reduce its manufacture cost; Improve bulk strength and precision, shortened technological process.
2, there are not defectives such as rosin joint, sealing-off, not prison welding in the integral structure of output shaft of gear-box and power shift gear, and what ensure the transmission of power of automobile, steady gearshift carries out the support vehicles safety traffic smoothly.
3, gear shift operation flexibly, conveniently improves travelling comfort.
4, prolong its working life, high life.
Description of drawings
Fig. 1 is the utility model structural front view (part is analysed and observe).
Embodiment
As shown in the figure, the integral structure of automobile gearbox output shaft of the present utility model and power shift gear, comprise output shaft 1, its improvements are, end at output shaft 1, (making) is set gearshift small gear 2 and gearshift gearwheel 3, and described gearshift small gear 2, gearshift gearwheel 3 and output shaft 1 are integral structures, become as a whole.The diameter of gearshift gearwheel 3 is greater than the diameter of gearshift small gear 2, and gearshift small gear 2 is near the end of output shaft 1.Parameters such as the number of teeth of gearshift small gear 2 and gearshift gearwheel 3, diameter, modulus need decision according to actual process.
Have gearshift small gear 2 and gearshift gearwheel 3 on the output shaft 1,, directly form an integral body, improved intensity and precision with output shaft 1 because the facewidth direction of the requirement of intensity gearshift small gear 2 does not have tool withdrawal groove.Gearshift small gear 2 and gearshift gearwheel 3 form two duplicate gears, finish the gearshift effect jointly.The utility model can adopt and forge the integral structure that processing technology obtains output shaft and power shift gear.
Claims (3)
