Abstract
An output shaft of a gearbox comprises a mounting shaft neck part consisting of a first gear mounting shaft neck, a second gear mounting shaft neck, a reverse gear mounting shaft neck, a fixed gear mounting shaft neck and a synchronizer mounting shaft neck; the installation journal part is provided with a first gear installation journal and a second gear installation journal which are journals with uniform basic sizes except the reverse gear installation journal, the reverse gear journal is a journal with a smaller diameter and is connected with the journals with uniform basic sizes, the other end of the journal with uniform basic sizes is provided with a positioning shoulder, and the journal with uniform basic sizes is also provided with an integral axial spline for installing a synchronizer and a fixed gear seat. The output shaft of the gearbox can avoid the problems of the existing output shaft, a plurality of different shaft diameters are the shaft necks with the same basic size by matching the bearing sleeves on the mounting shaft necks for positioning, the tool withdrawal grooves are reduced, the strength and the rigidity of the shaft are improved, and the mounting is convenient; the axial dimension chain is short, the precision requirement is low, the processing is convenient, and the processing cost is reduced; the integral axial spline can adopt a spline rolling mode, and the process is simple and the efficiency is high.
Description
Technical field
The utility model relates to the automobile gearbox output shaft.
Background technique
At present, the structure of the output shaft of automobile gearbox is general: keep off respectively on the output shaft that gear is installed axle journal, fixedly toothholder splined shaft neck, synchronizer installation axle journal are the step axle, and shoulder is all arranged everywhere; Tool withdrawal groove has generally all been cut at each shoulder place.Be a kind of structure of existing output shaft as shown in Figure 1: second gear installation axle journal 1 is in the left side that synchronizer is installed axle journal 2, and the axle journal that synchronizer is installed axle journal 2 is big, installs between axle journal 1 and the synchronizer installation axle journal 2 at second gear and forms shoulder; On the right side that synchronizer is installed axle journal 2, first gear is installed axle journal 3, fixedly toothholder splined shaft neck 4, reverse gear are installed axle journal 5 and be multidiameter shaft successively and arrange, between a plurality of shoulders of formation.This output shaft shoulder, tool withdrawal groove are many, and stress concentration point is many, and the strength and stiffness of whole axle are low; Shoulder end face and axial dimension precision prescribed height, size chain length, processing difficulties, cost height.
Summary of the invention
Existing output shaft strength and stiffness are low in order to solve, processing difficulties, problem that cost is high, the utility model proposes a kind of output shaft of gear-box.
For this reason, the technical solution of the utility model is: a kind of output shaft of gear-box, comprise by first gear axle journal is installed, second gear is installed axle journal, reverse gear is installed axle journal, fixing toothholder installation shaft neck, synchronizer is installed the installation shaft neck position that axle journal is formed, it is characterized in that: on the described installation shaft neck position except that reverse gear is installed axle journal be, first gear is installed axle journal, second gear is installed the axle journal of axle journal for unified base dimension, the reverse gear axle journal is the smaller axle journal of diameter, it is connected with the axle journal of unified base dimension, the other end at the axle journal of unifying base dimension is provided with locating shoulder, also is provided with whole axial splines and reaches fixedly toothholder so that synchronizer to be installed on the axle journal of unified base dimension.
This output shaft of gear-box, by join the axle sleeve location on the installation axle journal, a plurality of different axle journals are combined into the axle journal of unified base dimension, and shoulder and tool withdrawal groove reduce, and the intensity of axle and rigidity are improved, and conveniently install; Simultaneously, do not have step between the installation axle journal of difference in functionality, the axial dimension chain is short, and required precision is low, and is easy to process; Whole axial splines can adopt the mode of non-gear shaping, the simple efficient height of technology.
Summary, the beneficial effects of the utility model are: stress concentration point is less, and the intensity of axle and rigidity improve; Simple in structure, good manufacturability has been reduced manufacturing process, has reduced manufacture cost and has improved manufacturing efficiency.The output shaft of this structure reduces by 5% at least than existing output shaft cost.
Description of drawings
Fig. 1 is the structural representation of existing output shaft.
Fig. 2 is a structural representation of the present utility model.
Fig. 3 is an installment state schematic representation of the present utility model.
Embodiment
Be a kind of structure of output shaft of gear-box as shown in Figure 2, its installation shaft neck position is installed axle journal 7a, synchronizer by second gear and is installed that axle journal 7b, first gear install axle journal 7c, fixedly toothholder installation shaft neck 7d, reverse gear installation axle journal 8 are formed; As shown in Figure 2, it on the described installation shaft neck position axle journal of unified base dimension, it is the smaller axle journals of diameter that reverse gear is installed axle journal 8, be connected with the axle journal of unified base dimension, the other end at the axle journal of unifying base dimension is provided with locating shoulder 6, is provided with whole axial splines and reaches fixedly toothholder so that synchronizer to be installed on the axle journal of unified base dimension.Whole axial splines by synchronizer spline on the axle journal 7b is installed, fixedly spline and the middle transition spline on the toothholder installation shaft neck 7d constitutes continuously.
In conjunction with Fig. 2, as can be seen, installation shaft neck position has only a shoulder, and tool withdrawal groove has only 2.And original output shaft shoulder has 3, and tool withdrawal groove has 4.Relatively find out, avoided original axle upper shoulder many, the problem that difficulty of processing is big.
Be the installation signal of output shaft of gear-box as shown in Figure 3.Second gear 9, synchronizer peace 10, first gear 11, fixedly toothholder 12, reverse gear 13 are installed in corresponding axle journal position successively, and locate with locating shoulder 6 in the left side.Synchronizer is installed axle journal 10, fixedly toothholder 12 directly is connected with whole axial splines, and second gear 9, first gear 11, reverse gear 13 are supported on the corresponding axle journal by bearing housing 16, bearing housing 15, bearing housing 14.
In conjunction with Fig. 3, as can be seen, installation shaft neck position has only a shoulder, and tool withdrawal groove has only one, and stress concentration point is few, thereby the intensity of axle, highly improves, and also convenient simultaneously installation is time saving and energy saving.
