Abstract
The utility model discloses a clutch inner hub. The clutch inner hub comprises an inner hub body, wherein a friction plate set is arranged outside the inner hub body; an inner hub cavity is formed inside the inner hub body; an oil hole is formed in the side surface of the inner hub body; the oil hole runs through the side surface of the inner hub, so that the inner hub cavity is communicated with the outer side surface; and an oil storage slot is formed in the end surface of the left side of the inner hub body. The technical scheme is adopted, so that the clutch has a simple structure and long service life; and the oil storage slot is used for preventing lubricating oil from flying out of the inner hub due to centrifugal force, so that the friction plate set lubrication can be achieved well.
Description
Technical field
The utility model relates to clutch field, relates to specifically hub in a kind of clutch.
Background technique
Clutch generally uses in speed changer and driving mechanism, and clutch member comprises interior hub, outer hub, friction plate group, piston, equalizing piston, return spring etc.It is inboard that interior hub is positioned at the friction plate group, by some supporting elements or link and other outer hub, transmission shaft, planet row or gear links together, have oilhole on the interior hub wall, lubricant oil by in the oilhole engaging friction sheet group, is friction plate group Cooling and Lubricator under the effect of centrifugal force.
In each member of speed changer, the friction plate group of clutch is than the part that is easier to Yin Gaowen and friction damage, because speed changer is by the separation of friction plate group with in conjunction with realizing shifting gears, when the friction lining face of friction plate group can not be realized its function or damage because Cooling and Lubricator is not in place, will affect the working life of clutch, and then affect the quality of gearbox.
For to friction plate group fuel feeding better, usually by adding a special oil supply system or strengthening fuel delivery and realize purpose, will make the internal structure complicated like this, increase the size of whole speed changer, make troubles also for simultaneously the control of hydraulic system.
Summary of the invention
Problem to be solved in the utility model provides the interior hub of clutch lubricated, long service life that a kind of internal structure is simple, can be good at realizing the friction plate group.
In order to address the above problem, the utility model by the following technical solutions:
Hub in a kind of clutch comprises interior hub body, and the outside of described interior hub body is provided with the friction plate group, be provided with interior hub chamber in the interior hub body, the side of interior hub body is provided with oilhole, and the side that oilhole runs through interior hub is communicated with interior hub chamber with outer side surface, and the left end face of described interior hub body is provided with the pocket oil groove.
The utility model adopts said structure, so that the knot clutch configuration is simple, and long service life, the pocket oil groove is used for preventing lubricant oil and outside the interior hub chamber, can realizes well realizing that the friction plate group is lubricated because centrifugal force flies out.
Below in conjunction with drawings and Examples the utility model is done further and to be specified.
Description of drawings
Accompanying drawing 1 is the utility model embodiment's structural representation;
Accompanying drawing 2 is the left view of accompanying drawing 1.
Among the figure, 1-friction plate group; Hub body in the 2-; The 3-oilhole; 4-pocket oil groove; Hub chamber in the 5-.
Embodiment
Embodiment, as shown in Figure 1, hub in a kind of clutch, comprise interior hub body 2, the outside of described interior hub body 2 is provided with friction plate group 1, is provided with interior hub chamber 5 in the interior hub body 2, and the side of interior hub body 2 is provided with oilhole 3, the side that oilhole 3 runs through interior hub 2 is communicated with interior hub chamber 5 with outer side surface, the left end face of described interior hub body 2 is provided with pocket oil groove 4.
When clutch was worked, lubricant oil entered interior hub chamber 5 by oil duct, enters oilhole 3 along pocket oil groove 4 under the effect of centrifugal force, thereby was that friction plate group 1 realizes lubrication and cooling.
