The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
[0054] Some embodiments of the present application are described in detail. The following embodiments and features of the embodiments can be combined with each other in the case of no conflict.
[0055] Referring to Figure 1 The present embodiment provides a vehicle 300, comprising a vehicle body 301 and a drive system 200. The drive system 200 is mounted to the vehicle body 301.
[0056] Referring to Figure 2 The drive system 200 comprises a wheel hub 201, a wheel hub bearing 202, a drive shaft 203 and a gasket 100. The wheel hub bearing 202 is fixedly arranged on the wheel hub 201. One end of the drive shaft 203 is arranged in the wheel hub bearing 202, and the other end of the drive shaft 203 is used to be connected to a power device (not shown in the figure) to output power to the wheel hub bearing 202, thereby driving the wheel hub 201 to rotate. The gasket 100 is arranged between the wheel hub bearing 202 and the drive shaft 203.
[0057] Referring to Figure 3 and Figure 4The gasket 100 comprises a base layer 10, a contact layer 20 and a filling portion 40. The contact layer 20 comprises a plurality of contact portions 30, one end of the plurality of contact portions 30 is inserted into the base layer 10 and connected with the base layer 10, the other end of the plurality of contact portions 30 extends in a direction away from the base layer 10, and the side of the plurality of contact portions 30 away from the base layer 10 forms a contact surface P1. The contact surface P1 can be used to contact the drive shaft 203 or the hub bearing 202, thereby reducing friction and damping when the drive shaft 203 and the hub bearing 202 are axially impacted or radially rotated, to alleviate the noise generated during the operation of the drive system 200, and to reduce the wear caused by the collision between the drive shaft 203 and the hub bearing 202. The filling portion 40 fills the gap G formed between the plurality of contact portions 30.
[0058] The base layer 10 can stably support the contact portions 30, improve the overall strength and toughness of the gasket 100. The contact portions 30 are inserted into the base layer 10, so that the contact portions 30 are not easy to fall off from the base layer 10, and the contact layer 20 remains connected to the base layer 10. Under long-term impact, the contact surface P1 of the contact layer 20 can still remain intact, providing better impact resistance and friction reduction effect. At the same time, the filling portion 40 fills the gap G formed between the plurality of contact portions 30, so that the contact portions 30 and the filling portion 40 reinforce each other, which can further improve the overall strength and toughness of the contact layer 20, thereby further reducing the possibility of the contact layer 20 falling off when being pressed and impacted, ensuring the service life of the gasket 100, and reducing the maintenance frequency of the gasket 100. Therefore, according to the gasket 100 of the embodiment, the impact resistance and service life of the gasket 100 can be improved.
[0059] In addition, after the gasket 100 of the embodiment is installed in the drive system 200, it can play a role in damping and reducing friction between the drive shaft 203 and the hub bearing 202 for a long time, thereby alleviating the wear between the drive shaft 203 and the hub bearing 202 and reducing the noise during the operation of the drive system 200.
[0060] In some embodiments, the base layer 10 has a first surface P2, and the contact portions 30 are inserted into the base layer 10 from the first surface P2. The contact portions 30 can or can not penetrate the base layer 10. The plurality of contact portions 30 are arranged at intervals from each other in a regular or irregular manner on the first surface P2 to form gaps G accommodating the filling portion 40. Among them, the plurality of contact portions 30 can be spaced apart from each other and not in contact with each other, or can be staggered with each other and form different gaps G.
[0061] In other embodiments, the radial side surface of the base layer 10 can also be additionally provided with a plurality of contact portions 30 and a filling portion 40.
[0062] In some embodiments, the material of the filling portion 40 can be resin. The resin can be fluororesin, such as polytetrafluoroethylene. In different embodiments, the melting point of the resin can be set to be lower than the melting point of the contact portion 30, so that the resin can be melted and then solidified to form the contact layer 20. The resin can be filled into the gap G in a liquid state.
[0063] In some embodiments, referring to Figure 5 , the substrate layer 10 has a first surface P2 and a second surface P3 arranged oppositely, and the contact portion 30 has a wire structure. The contact portion 30 penetrates the substrate layer 10 from one side of the first surface P2, penetrates the substrate layer 10 from the second surface P3, and then extends out of the first surface P2 to form the contact layer 20 on one side of the first surface P2. In this way, the processing convenience of the contact portion 30 can be improved, and the contact portion 30 is less likely to be separated from the substrate layer 10.
[0064] In the present embodiment, one end of the contact portion 30 abuts against the second surface P3, and the other end of the contact portion 30 penetrates out of the first surface P2 and extends in a direction away from the first surface P2 to form only one contact layer 20 on one side of the first surface P2 of the substrate layer 10. Each contact portion 30 has a substantially U-shaped structure. In other embodiments, one contact portion 30 can be arranged to reciprocate between the first surface P2 and the second surface P3 to form the contact layer 20.
[0065] The wire structure refers to a wire structure with a relatively small diameter and a relatively long length. In the present embodiment, the diameters of the plurality of contact portions 30 can be equal or within a preset range, for example, the preset range can be set to be between 0.05 mm and 0.25 mm. The preset range can be adjusted according to the specific material of the wire structure. The material of the contact portion 30 can be a fiber wire such as glass fiber, polytetrafluoroethylene, or metal, thereby providing self-lubricating effect and further improving the effect of reducing the friction of the contact surface P1.
[0066] In some embodiments, referring to Figure 5 , the substrate layer 10 has a first thickness H1 (i.e., the distance between the contact surface P1 and the first surface P2), and the gasket 100 has a second thickness H2 (i.e., the distance between the first surface P2 and the second surface P3). In this case, H1 < H2, 0.7 mm ≤ H1 ≤ 0.9 mm, and 0.9 mm ≤ H1 ≤ 1.2 mm.
[0067] In some embodiments, the substrate layer 10 is a woven structure made of wires, and the contact portions 30 pass through the internal space of the woven structure. In this way, the difficulty of the contact portions 30 passing through the substrate layer 10 can be reduced, thereby improving the processing efficiency of the gasket 100. Moreover, when the substrate layer 10 needs to be configured in different forms, the woven structure has less material waste, which can reduce the cost of the gasket 100 and improve the application range.
[0068] Specifically, the wires can be glass fiber wires, and the woven structure is a glass fiber cloth. For example, the substrate layer 10 can be formed by flattening a woven cylindrical structure along the cylinder axis direction, thereby facilitating the formation of a woven structure with high density, and further improving the strength of the gasket 100. In other embodiments, the material of the wires can be polytetrafluoroethylene or metal, etc.
[0069] In some embodiments, referring to Figure 4 and Figure 5 , the shape of the contact portion 30 is grid-shaped, S-shaped or ring-shaped in the cross section perpendicular to the plane of the contact surface P1. Through the design of the contact portion 30 with different shapes, the density of the contact layer 20 can be improved under the condition that the thickness of the contact layer 20 is constant, and the filling reliability between the contact portion 30 and the filling portion 40 can also be improved, thereby reducing the possibility of the filling portion 40 falling off, and further realizing the maintenance-free function of the gasket 100 in the whole life cycle.
[0070] In the grid-shaped contact portion 30, a plurality of contact portions 30 are woven to form a whole structure in a grid shape. The plurality of woven portions can form a grid shape in a warp and weft weaving manner. According to different weaving manners of the contact portion 30, the plurality of grids formed between the plurality of contact portions 30 can be circular, rectangular or other different shapes.
[0071] In some embodiments, referring to Figure 6 , the substrate layer 10 is provided with a mounting hole K configured to accommodate a target piece. The target piece is a drive shaft 203. The drive shaft 203 is arranged in the mounting hole K to realize the installation of the gasket 100 between the drive shaft 203 and the hub bearing 202.
[0072] In some embodiments, the mounting hole K has a circular, square, elliptical, non-concentric circular or other special shape to meet the installation requirements between different components of the vehicle 300.
[0073] In some embodiments, referring to Figure 6 and Figure 7 , the gasket 100 further comprises a limiting portion 50 connected to the substrate layer 10, and the limiting portion 50 is used for limiting cooperation with the target piece. In order to improve the positional stability between the gasket 100 and the target piece, and reduce the possibility of the gasket 100 moving relative to the target piece.
[0074] In some embodiments, the limiting portion 50 can be integrally formed on the substrate layer 10. The limiting portion 50 can also be a component independent of the substrate layer 10 and fixed to the substrate layer 10 by brazing, gluing or other means such as embroidery.
[0075] In some embodiments, the limiting portion 50 is arranged at the outer edge of the substrate layer 10 and / or the inner edge of the substrate layer 10.
[0076] For example, Figure 6 In the illustrated substrate layer 10, the limiting portion 50 is arranged at the outer edge of the substrate layer 10 and extends outward along the distribution direction of the first surface P2 and the second surface P3. Figure 7 In the illustrated substrate layer 10, the limiting portion 50 is arranged at the inner edge of the substrate layer 10 and extends outward along the distribution direction of the first surface P2 and the second surface P3, and the limiting portion 50 is also arranged to be inclined towards the inner side of the mounting hole K. The specific structure of the limiting portion 50 can be adjusted according to the installation environment of the gasket 100, which is not limited in the present embodiment.
[0077] In some embodiments, the number of limiting portions 50 is multiple, and the multiple limiting portions 50 are distributed along the circumference of the substrate layer 10 to improve the limiting and fitting reliability of the gasket 100 and the target piece.
[0078] In other embodiments, the gasket 100 can also be applied between other two components of the vehicle 300 that are subject to friction and / or impact. For example, the gasket 100 can be applied to the exhaust pipe, cylinder head and other positions of the engine, or arranged between the battery box and the battery box cover.
[0079] The following refers to Figure 8 and Figure 9 A gasket 100 of another embodiment of the present application is described. In this embodiment, the contact layer 20 has a first surface P2 and a second surface P3 arranged opposite to each other, and the number of contact layers 20 is two, with the two contact layers 20 respectively located on the first surface P2 and the second surface P3. In this way, one side of the first surface P2 and one side of the second surface P3 are both formed with a contact surface P1, so that both sides of the gasket 100 can be in contact with two components at the same time. The structure of the two contact layers 20 can refer to the structure of the contact layer 20 of the foregoing embodiments, which will not be described here.
[0080] In the present embodiment, the weaving manner of the plurality of contact portions 30 can be plain stitch, thread stitch, double reverse stitch, etc., and the plurality of contact portions 30 can be woven by reciprocatingly penetrating along the first surface P2 and the second surface P3 of the substrate layer 10, so as to form a contact surface P1 on both sides of the first surface P2 and the second surface P3, thereby providing lubrication and reducing friction on both side surfaces of the gasket 100.
[0081] The above embodiments are only used to illustrate the technical solutions of the present application but not limit the present application, and although the present application has been described in detail with reference to the above preferred embodiments, those ordinarily skilled in the art should understand that the technical solutions of the present application can be modified or equivalent replaced without departing from the spirit and scope of the technical solutions of the present application.
