Detailed Description
The present invention will be described with reference to fig. 1 to 4.
The aluminum alloy clutch oil seal cover comprises an oil seal cover body 1, an outer sealing component 2 and an inner sealing component 3, wherein a first annular groove 10 is formed in the circumferential surface of the oil seal cover body 1, a first through hole 11 is formed in the axial end face of the oil seal cover body 1, the outer sealing component 2 is matched with the first annular groove 10, the inner sealing component 3 is matched with the first through hole 11, first bulges 12 which reduce the deformation of the oil seal cover body 1 and are positioned on two sides of the first annular groove 10 are arranged on the oil seal cover body 1, and second bulges 13 which reduce the deformation of the oil seal cover body 1 and surround orifices of the first through hole 11 are further arranged on the oil seal cover body 1.
In this embodiment, its oil seal cover body 1 adopts the mould casting shaping, through set up first arch 12 and second arch 13 on oil seal cover body 1 after for oil seal cover body 1 can promote by a wide margin at global rigidity of position and middle part position, can bear bigger atmospheric pressure, and the deflection is littleer (maximum deformation 0.2 mm), and sealed effect is also better.
The structure of the oil sealing cover body 1 changes along with the change of the outline of the clutch, a safe distance needs to be kept between the structure and the clutch and between the structure and the dual-mass flywheel outside the transmission, and the platformization and the compatibility can be considered during the design of the oil sealing cover body 1.
The oil seal cover body 1 is further provided with a mounting seat 14 which extends to the outside of the peripheral surface of the oil seal cover body 1 and is used for axially positioning the oil seal cover body 1. In the utility model, the fixation of the oil sealing cover body 1 and the circumferential sealing are realized by separating, the fixation of the oil sealing cover body 1 adopts the mounting seat 14 which is integrally formed with the oil sealing cover body 1 to carry out axial limiting, for example, the mounting seat 14 and a box body are fastened into a whole through a screw, so that the axial stress of the oil sealing cover body 1 is born by the mounting seat 14, and the condition that the oil sealing cover body 1 is pressed and deflected to form a height difference is avoided. And sealed adopt external seal part 2 (external seal part 2 adopts O shape sealing washer) to inlay and combine the box and realize radial seal in first annular 10 together, because first annular 10 is that later stage passes through the machine and adds the assurance size precision, therefore, it is transition fit to be located the first annular 10 both sides global and the box on the oil cap body 1, can form radial spacing to the oil cap body 1 of can the at utmost, again because aluminum alloy lid and box adopt the same kind of material, its coefficient of expansion is unanimous, can make external seal part 2 circle be in the most suitable application range all the time, thereby guarantee sealed effect.
The oil seal cover is characterized in that a raising pressing plate 15 used for detaching the oil seal cover body 1 is further arranged on the oil seal cover body 1, one part of the raising pressing plate 15 extends to the periphery of the oil seal cover body 1, and a cavity for inserting a raising tool is formed between the raising pressing plate 15 and the oil seal cover body 1. In this embodiment, the raising press plate 15 is preferably combined with the first protrusion 12. More preferably, the raising press plate 15 is also combined with the mount 14.
The raising pressing plate 15 and the oil seal cover body 1 are integrally formed, when the oil seal cover body 1 is required to be detached, the oil seal cover body 1 can be raised or hooked only by a plurality of hooks or a slightly long screwdriver, so that the oil seal cover body 1 is separated from the box body, the box body and the oil seal cover can be protected to the maximum extent, and the oil seal cover is used for repeatedly utilizing assistance.
In this embodiment, one part of the circumferential surface of the oil seal cover body 1 is in transition fit with the box body, and the other part of the circumferential surface of the oil seal cover body 1 is in clearance fit with the box body, so that the circumferential surface of the oil seal cover body 1 does not scratch the outer seal member 2 when the oil seal cover is first assembled, and therefore, the oil seal cover used once can determine whether the oil seal cover can be reused (the seal O ring can be replaced if necessary) only by checking whether the groove surface of the first ring groove 10 and the circumferential surface of the oil seal cover body 1 have scratches or not and scratches;
the middle part of the oil seal cover body 1 is provided with a bulge part 16 for clamping when the oil seal cover body 1 is machined. Because the oil seal cover needs to be clamped and machined again after being demoulded (for example, the first annular groove 10 is machined), and process clamping needs to be considered, the bulge part 16 is arranged on the oil seal cover body 1, and the height of the bulge part 16 can meet the clamping requirement. The bulge portion 16 may be formed by a die at the time of casting, or may be formed by press molding after casting, in which the bulge portion 16 is formed by pressing from one axial end surface of the oil cap body 1 to the other axial end surface.
The assembly position of the inner sealing component 3, because the whole oil sealing cover body 1 adopts machining, the axial position of the first through hole 11 for installing the inner sealing component 3 can be adjusted according to the calculation result of the dimension chain of each transmission, and the installation chamfer angle for adjusting the inner sealing component 3 is formed in the first through hole 11 to determine the installation position of the sealing component 3.
In this embodiment, the inner seal member 3 includes an outer seal portion 31, a lip edge 32, a main lip 33, a sub lip 34, and a spring 35, the outer seal portion 31 is annular, an outer peripheral surface of the outer seal portion 31 is fitted to a hole wall surface of the first through hole 11, one end of the main lip 33 is coupled to the inner peripheral surface of the outer seal portion 31, the main lip 33 is inclined in an axial direction of the outer seal portion 31 such that the other end of the main lip 33 extends toward a middle portion of the outer seal portion 31, one end of the lip edge 32 is coupled to the other end of the main lip 33, the other end of the lip edge 32 extends toward an inner wall of the outer seal portion 31, a groove is formed between the lip edge 32 and the main lip 33, and the spring 35 is installed in the groove. When the device is installed, the input shaft or the clutch shaft penetrates through the inner sealing part 3, the input shaft or the clutch shaft is matched with the main lip 33, and the main lip 33 is tightly matched with the input shaft or the clutch shaft under the contraction action of the spring 35.
Finally, it should be noted that: the above embodiments are only preferred embodiments of the present invention to illustrate the technical solutions of the present invention, but not to limit the technical solutions, and the patent scope of the present invention is not limited; while the utility model has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention; in addition, the technical scheme of the utility model is directly or indirectly applied to other related technical fields, and the technical scheme is included in the patent protection scope of the utility model.
