Description
Technical field
The utility model belongs to technical field of mechanical transmission, is specifically related to a kind ofly prevent reverse gear sliding gear out of supply.
Background technique
Gearbox is made up of gear and axle, and produce variable-speed torque-converting by different Gear combination, its function mainly contains: 1, change velocity ratio; 2, in the constant situation of hand engine rotation, automobile can be fallen back traveling; 3, utilize neutral, interrupt transmission of power, to start to enable motor, idling, and be convenient to shifting of transmission or carry out Power output.The reverse gear sliding gear of gearbox generally adopts spline package on reverse gear axle, and under the effect of shift fork, reverse gear sliding gear slides along reverse gear axle, and its spline is engaged with two rooted tooth wheel shafts, to realize the object of transferring power simultaneously simultaneously.Although existing reverse gear sliding gear can meet usage requirement to a certain extent, when reverse gear slip is engaged with other gear shaft engage a gears, there is defect easy and that reverse gear axle is out of supply.
Summary of the invention
In view of this, the purpose of this utility model is to provide a kind of anti-reverse gear sliding gear out of supply, can prevent out of supply.
For achieving the above object, the utility model provides following technological scheme:
A reverse gear sliding gear anti-out of supply, comprise gear, the center of described gear is provided with central through bore, is provided with internal spline in described central through bore, and one end of the periphery wall of described gear is provided with driving gear, and the other end is provided with fork slot; The separation annular groove for described internal spline being divided into two sections is provided with in described central through bore, and all spline tooths being positioned at one section of internal spline of side, described driving gear place are all set to teeth, the direction that the width of described teeth points to fork slot along described driving gear reduces gradually, and the direction that the root diameter of described teeth points to described fork slot along described driving gear increases gradually.
Further, described teeth is arranged axisymmetricly.
Further, described teeth symmetry plane is fallen in and angle between the dual-side in the cross section intercepted on corresponding described teeth with the plane of the axis being parallel of described gear is 6 °.
Further, the end face of described teeth comprises the front-end face being positioned at middle part and the angled end-face being positioned at both sides, and described front-end face is inclined to set relative to the axis of described gear.
Further, the angle between two described angled end-faces is 115-120 °, and the angle between the axis of described front-end face and described gear is 82 °.
The beneficial effects of the utility model are:
Anti-reverse gear sliding gear out of supply of the present utility model, by arranging teeth on internal spline, when reverse gear sliding gear be sleeved on gear shaft slides time, due to the existence of this teeth, effectively can avoid out of supply, make the reliability of gearbox higher.
Accompanying drawing explanation
In order to make the purpose of this utility model, technological scheme and beneficial effect clearly, the utility model provides following accompanying drawing to be described:
Fig. 1 is the structural representation that the utility model prevents reverse gear sliding gear embodiment out of supply;
