Description
Technical field
The utility model is related to the output shaft on gearbox, more particularly to a kind of automobile gearbox.
Background technology
Speed changer is that, for changing the rotating speed from engine and the mechanism of torque, it can be fixed or stepping changes output shaft
With input shaft gearratio, also known as gearbox.Equipped with five shifting gears, an output gears on existing five grades of output shaft of gear-box
Wheel, synchronizer and bearing, because each component distribution on output shaft is unreasonable, cause the complicated of output shaft of gear-box, plus
Work difficulty is big, process is more, can influence processing efficiency, increases production cost.Answered in addition, output shaft easily leaves in process
The situation that power is concentrated, so as to bring the fragile flimsy problem of output shaft, existing output shaft of gear-box can not accurately know institute
The stress born, thus its service life can not be accurately held.
Utility model content
In view of the drawbacks described above of prior art, technical problem to be solved in the utility model is to provide a kind of new defeated
Shaft.
Technical solutions of the utility model are as follows：A kind of new output shaft, with output shaft body, it is characterised in that：It is described
The front end for exporting shaft body sets fore bearing axle journal, bearing journal after the follower head setting of output shaft body, in the front axle
Hold and set gradually changeover portion, first gear axle journal, second gear axle journal, the 3rd tooth between axle journal and rear bearing journal from front to back
Axle journal, one or two grades of splines and output spline are taken turns, is separated between the output spline and one or two grades of splines by annular groove, output spline
Diameter is equal to the diameter of one or two grades of splines, and the diameter of one or two grades of splines is more than the diameter of the 3rd gear axle journal, the 3rd gear axle journal
Diameter be more than the diameter of second gear axle journal, the diameter of second gear axle journal is more than the diameter of first gear axle journal, the first tooth
The diameter for taking turns axle journal is more than the diameter of changeover portion, and the diameter of changeover portion is more than the diameter of fore bearing axle journal, the fore bearing axle journal
Diameter it is equal with the diameter of rear bearing journal, be formed with circumferentially equally distributed end in the rear end face of rear bearing journal
Face tooth.
Using above technical scheme, fore bearing axle journal and rear bearing journal are used to install bearing；First gear axle journal is used for
Five shelves gears are installed, second gear axle journal is used to install fourth gear, and the 3rd gear axle journal is used to install third gear, one or two grades
Spline is used to install intermediate gear, synchronizer and a shelves gear successively from front to back, and output spline is used to install output gear.This
Utility model is on the one hand simple in construction, and regular shape, processing and fabricating is easy, it is possible to increase processing efficiency, effectively reduces production
Cost；On the other hand, the part connection and reasonable arrangement such as gear on output shaft, is conducive to installation operation, can greatly improve packaging efficiency.
Separated between output spline and one or two grades of splines by annular groove, distance of the spline along axis body axial direction can be shortened, also to a certain degree
On reduce stress weakness；Output shaft rear end face set end-tooth, when needing can power taking at this, with tradition
Flat recess structure compare, end-tooth transmission is more steady, reliable.
Sensing chip is set on the bottom land and changeover portion of the annular groove.Sensing chip can stress suffered by inductive output axle, lead to
Cross wireless device to be shown on automobile display screen, so as to accurately hold the service life of output shaft.
Beneficial effect：The utility model is ingenious in design, simple in construction, and easily, production cost is low, structural strength for processing and fabricating
Good, service life is long, can conveniently carry out power taking, and is conducive to the parts such as shifting gear to install, and can effectively improve installation effect
Rate.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples：
As shown in figure 1, the output shaft of five grades of gearboxes of automobile has output shaft body, the front end of the output shaft body is set
