Description
Technical field
The utility model relates to a kind of gearbox component, especially relates to a kind of gearbox fourth gear driven gear forging piece.
Background technique
Have employed automatic mechanical transmission in existing vehicle, it increases automatic shift system on the basis of the fixing shaft type transmission system of step type machinery, by electronic control gear-selecting-shifting mechanism, thus replaces manpower to complete gear selecting and gear shift.Chinese patent discloses a kind of pure mechanical electric motor-car four speed transmission (Authorization Notice No.: CN204213276U), it comprises housing, input shaft, front moving axis, rear moving axis, output gear, input shaft, front moving axis, rear moving axis are arranged in housing by bearing, and output gear fixed cover is loaded on the axle for outputting power on housing; The outer order motor power input of input shaft, is rotated by the front moving axis of combination of gear, sliding sleeve, sliding sleeve tooth, rear moving axis, output gear and is realized four-speed gear shift; Input shaft, front moving axis, rear moving axis and output gear circle core shaft are positioned at same mold joint; Input shaft is fixed with input tooth, position relative with input tooth on front moving axis is fixed with front driven tooth, input tooth and the engagement of front driven tooth; Front moving axis being also equipped with successively fixing front driving tooth, rotating first slip teeth, engagement are fixing can sliding sleeve, rotating second slip teeth in axial sliding, and wherein sliding in the middle of the first slip teeth and the second slip teeth can any one be nested and drives or be separated from each other with the first slip teeth or the second slip teeth; Before corresponding on rear moving axis, rotating 3rd slip teeth is equipped with in the position of driving tooth, and the 3rd slip teeth engages with front driving tooth; On rear moving axis, be fixed with can sliding sleeve tooth in axial sliding in the position engagement of corresponding first slip teeth, and sliding sleeve tooth engages with the first slip teeth; On rear moving axis, the position of corresponding second slip teeth is fixed with rear driven tooth, and rear driven tooth engages with the second slip teeth; The position of the corresponding output gear of rear moving axis is fixed with rear driving tooth, and rear driving tooth engages with output gear; Sliding sleeve tooth drives by sliding to be nested with the 3rd slip teeth on rear moving axis or is separated from each other; Differential mechanism is also equipped with in output gear position on housing; There is depression at the middle part of sliding sleeve and sliding sleeve tooth, and sliding sleeve medial recess position card has front shift fork, and sliding sleeve tooth medial recess position card has rear shift fork; Sliding sleeve realizes sliding axially at front moving axis by the mobile of front shift fork; Sliding sleeve tooth realizes sliding axially on rear moving axis by the mobile of rear shift fork.But the gear that this speed changer adopts is in use, and it is easily at rupture, and the transmission shaft that easily weares and teares, during Vehicle Processing, location is more inaccurate in addition, and precision is poor.
Model utility content
The utility model is to provide a kind of gearbox fourth gear driven gear forging piece, it mainly solves the gear of the speed changer employing existing for prior art in use, it is easily at rupture, and easily wear and tear transmission shaft, during Vehicle Processing, location is more inaccurate in addition, the technical problem of the poor grade of precision.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
Gearbox fourth gear driven gear forging piece of the present utility model, comprise gear, the side of described gear is provided with arc steps, the inner of arc steps is provided with the first annular groove, the opposite side of gear is provided with the second annular groove, the width of the second annular groove is greater than the width of the first annular groove, and the outer end of arc steps is provided with strengthening groove, and strengthening groove is oblique setting.Strengthening groove can when gear be heat-treated, and feed liquid can enter in strengthening groove, makes its this part intensity comparatively strong, whole gear therefore can be prevented at rupture.
As preferably, the inwall of the through hole of described gear has some cavitys, the opening width of cavity is less than cavity inside width.Gear in use, can collect in cavity, and because opening is less, therefore dust is not easily run out of by the dust chip of generation, thus ensure the normal use of gear.
As preferably, the bottom of the second described annular groove is provided with some boss.Boss can so that the location of gear when machining, and can prevent from damaging the second annular groove bottom surface during Vehicle Processing.
Therefore, the utility model utilizes strengthening groove, can ensure the intensity of whole gear, and transmission shaft not easy to wear, during Vehicle Processing, location is comparatively accurate, and quality of fit is higher, simple and reasonable for structure.
Accompanying drawing explanation
Accompanying drawing 1 is a kind of structural representation of the present utility model;
Accompanying drawing 2 is A-A cross-sectional view of Fig. 1.
Component, position and numbering in figure: gear 1, arc steps 2, first annular groove 3, second annular groove 4, strengthening groove 5, boss 6, cavity 7.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: the gearbox fourth gear driven gear forging piece of this example, as shown in Figure 1, Figure 2, comprise gear 1, the side of gear is provided with arc steps 2, the inner of arc steps is provided with the first annular groove 3, and the width that the opposite side of gear is provided with the second annular groove 4, second annular groove is greater than the width of the first annular groove, the outer end of arc steps is provided with strengthening groove 5, and strengthening groove is oblique setting.The inwall of the through hole of gear has some cavitys 7, the opening width of cavity is less than cavity inside width.The bottom of the second annular groove is provided with some boss 6.
During use, after the utility model being carried out rough turn, finish turning, be encased in gearbox.
The foregoing is only specific embodiment of the utility model, but structure characteristic of the present utility model is not limited thereto, any those skilled in the art is in field of the present utility model, and the change done or modification are all encompassed among the scope of the claims of the present utility model.
