Description
Technical field
The utility model belongs to automatic transmission field, specifically, particularly relates to a kind of input shaft of automatic transmission.
Background technique
The input shaft right part of existing automatic transmission on case of transmission, so just causes input shaft towards both direction clockwise and anticlockwise, thus can cannot meet the functional requirement of speed changer by bearings.In order to meet the functional requirement of speed changer, we expect being set with an overrunning clutch in the right part of input shaft, need structure and the size of corresponding adjustment input shaft right part for this reason, propose present patent application for this reason.
Model utility content
Technical problem to be solved in the utility model is the input shaft providing a kind of automatic transmission, so that can at the right part of this input shaft suit overrunning clutch.
The technical solution of the utility model is as follows: a kind of input shaft of automatic transmission, is characterized in that: axle body (1) left part of this input shaft is outer spline section (1a), and the length of this outer spline section (1a) is
and the left part of axle body (1), middle part and right part are cylindrical section; The right part of described axle body (1) is overrunning clutch assembly department (1b), and this assembly department is left large, right little two-part hierarchic structure, and the diameter of its large footpath section is
its length is 7.7mm, and the diameter of path section is greater than the diameter of axle body (1) cylindrical section, and the diameter of this path section is
its length is 14.62mm; The center of described axle body (1) right side has first mating groove (1c), the diameter of this first mating groove is 27.78mm, its length is 3mm, and the center of the first mating groove (1c) bottom land has second mating groove (1d), the diameter of this second mating groove is 10mm, and its length is 5mm;
The right part of described axle body (1) has a center oil-feed blind hole (1e), the right-hand member of this center oil-feed blind hole is communicated with the bottom land of described second mating groove (1d), and the hole wall of center oil-feed blind hole (1e) is communicated with 4 radial oil outlets (1f); Described radial oil outlet (1f) left and right is arranged side by side, 3 radial oil outlets on the left side are located at axle body (1) left part, middle part and right part respectively, and a rightmost radial oil outlet (1f) is located in the path section of described overrunning clutch assembly department (1b).
During installation, overrunning clutch is connected with the overrunning clutch assembly department (1b) of axle body (1).During use, lubricant oil enters in center oil-feed blind hole (1e), and it is fuel-displaced by 4 radial oil outlets (1f), thus the parts of these 4 radial oil outlet (1f) place suits are lubricated, and the utility model just can install overrunning clutch by little change, thus allow this input shaft can only one-way rotation, and then meet the functional requirement of speed changer.
For the ease of installing retarder, the left end of described axle body (1) is made guiding conical end by spy, and this guiding conical end is of a size of 4.7*20 °.
As preferably, the material of described axle body (1) is 20CrMoH.
Beneficial effect: the utility model just can install overrunning clutch by the right part of changing axle body, thus allow this input shaft can only one-way rotation, and then meet the functional requirement of speed changer, and the utility model is changed easily, reequip with low cost, there is good practicability.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
