Embodiment Construction
[0030] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0031] Such as Figure 1 to Figure 10 As shown, the cylinder gasket of this embodiment is provided with an opening 4 suitable for the cylinder port on the gasket. The gasket includes an upper layer 1, a middle layer 3, and a lower layer 2. The middle layer 3 is sandwiched between the upper layer 1 and the lower layer 2. Between the lower layers 2, the top and bottom surfaces of the gasket are provided with ribs 31 that are extruded once and can improve the sealing performance and the bending strength. The ribs 31 on the top surface and the bottom surface are respectively composed of two sub-ribs. According to the design requirements, the two sub-ribs are protruded on the top surface of the gasket and partially separated from the corresponding positions according to the design requirements. On the bottom surface, the width of the two sub-ribs ...

The invention discloses an air cylinder sealing gasket. Openings (4) matched with an air cylinder opening are formed in the sealing gasket. The sealing gasket comprises an upper layer (1), a middle layer (3) and a lower layer (2). The middle layer (3) is clamped between the upper layer (1) and the lower layer (2). The top face and the bottom face of the sealing gasket are each provided with a convex rib (31) which is formed in a one-time extrusion manner and can improve the sealing performance and the bending resisting strength. The air cylinder sealing gasket has the beneficial effects that the top face and the bottom face of the sealing gasket are each provided with the convex rib (31) which is formed in the one-time extrusion manner so that the sealing performance and the bending resisting strength can be improved; the air cylinder sealing gasket is provided with the three layers, the upper layer and the lower layer are each provided with an annular reinforcing strip, and the top faces of the annular reinforcing strips are flush with the tops of metal lantern rings, so that the bending resisting capacity of the air cylinder sealing gasket is improved; the inner peripheral face of each opening is sleeved with the corresponding wear-resisting metal lantern ring, so that the service life of the air cylinder sealing gasket is prolonged, and the sealing effect is better; the wrapping depth of the metal lantern rings ranges from 2 mm to 6 mm so that the metal lantern rings cannot be loosened easily, and sealing performance is further improved; and a metal piece is arranged on a fixed through hole so as to be convenient to replace.
Description
technical field [0001] The invention relates to a motor vehicle component, in particular to a cylinder gasket and a manufacturing method thereof. Background technique [0002] An existing Chinese utility model patent with the patent number CN201420474877.X titled "Exhaust Pipe Gasket" discloses an exhaust pipe gasket, which includes an upper layer and a lower layer. fiberboard, the middle layer made of steel is sandwiched between the upper layer and the lower layer, the upper layer, middle layer and lower layer are integral plates connected together by glue, and the top surface of the upper layer and the bottom surface of the lower layer are convexly installed The convex edge that can improve the bending strength, the integral plate is provided with a round hole matching the diameter of the exhaust pipe, and an anti-friction metal collar is sleeved on the inner peripheral surface of the round hole. The utility model has the advantages of not being easily damaged, long servi...
