For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0045] Refer to the following Figures 1 to 7 A spring pad and a vehicle according to embodiments of the present application are described.

[0046] See also Figures 1 to 7 As shown, an embodiment of the present application provides a spring pad for an air spring, the air spring comprising at least an empty spring upper seat (not shown in the figure) and an empty spring lower seat 4 which are movably connected to each other, the empty spring upper seat or the empty spring lower seat 4 is provided with a mounting surface for mounting the spring pad. Of course, one spring pad can be installed on each of the empty spring upper seat and the empty spring lower seat 4 according to actual conditions.

[0047] Preferably, the spring washer is specifically installed to the empty spring lower seat 4 .

[0048] Specifically, the spring pad includes a main body 1, which is flexible. Preferably, the main body 1 is made of rubber material. It can separate the empty spring seat 4 from the lower swing arm 5 to avoid abnormal noise. It can also avoid rigid contact between the spring pad and the empty spring seat 4 and the lower swing arm 5, which may cause wear of the empty spring seat 4 and / or the lower swing arm 5.

[0049] The hollow spring lower seat 4 has a mounting surface, the shape of the main body 1 is adapted to the shape of the mounting surface, a hollow portion is formed at the center of the main body 1, so that the main body 1 as a whole has a sheet-like annular structure, the main body 1 has an inner ring 101 and an outer ring 102, and the inner ring 101 and the outer ring 102 are concentrically arranged.

[0050] The spring washer also includes an extension portion 2, which is arranged on a side surface of the main body 1 facing the lower swing arm 5. The extension portion 2 has a tube structure, and is arranged on the inner ring 101 of the main body 1. The extension portion 2 and the inner ring 101 are coaxially arranged. A central fixed tube 401 is arranged at the center of the empty spring lower seat 4, and the lower swing arm 5 is arranged around the central fixed tube 401. After the spring washer is installed in place, one side surface of the main body 1 is in contact with the installation surface of the empty spring lower seat 4, and the other side surface of the main body 1 is in contact with the lower swing arm 5, and the extension portion 2 is located between the central fixed tube 401 and the lower swing arm 5, so that the extension portion 2 can separate the central fixed tube 401 and the lower swing arm 5, thereby avoiding abnormal noise between the empty spring lower seat 4 and the lower swing arm 5.

[0051] Furthermore, a side surface of the main body 1 facing the air spring lower seat 4 is a first surface 103, and a side surface of the main body 1 facing the lower swing arm 5 is a second surface 104. Preferably, the first surface 103 and the second surface 104 are both circular surfaces, wherein the first surface 103 forms a limiting portion 3, and a reinforcing rib is arranged on the mounting surface. The shape of the limiting portion 3 matches the shape of the reinforcing rib. After the spring pad is installed in place, the reinforcing rib is embedded in the limiting portion 3, thereby limiting the spring pad to avoid twisting, displacement or even damage of the spring pad during the operation of the air spring.

[0052] Furthermore, the number of the limiting parts 3 is multiple, the number of the reinforcing ribs is also multiple, and the number of the limiting parts 3 is not less than the number of the reinforcing ribs. Preferably, in this embodiment, the number of the limiting parts 3 is the same as the number of the reinforcing ribs and corresponds one to one. Each reinforcing rib is correspondingly embedded in a limiting part 3, which on the one hand enhances the position stability of the spring pad relative to the empty spring lower seat 4, and on the other hand can ensure the flatness of the spring pad when assembled between the empty spring lower seat 4 and the lower swing arm 5.

[0053] Furthermore, the limiting portion 3 includes a limiting ring groove 301, which is arranged around the inner ring 101 on the first surface 103. Preferably, the limiting ring groove 301 is concentrically arranged with the inner ring 101, and the reinforcing rib includes an annular rib 402 arranged on the mounting surface of the empty spring lower seat 4. The shape of the limiting ring groove 301 is adapted to the shape of the annular rib 402, the diameter of the limiting ring groove 301 is the same as the diameter of the annular rib 402, and the width of the limiting ring groove 301 is the same as the thickness of the annular rib 402, so that the annular groove can be embedded in the limiting ring groove 301. Preferably, the width of the limiting ring groove 301 is slightly smaller than the thickness of the annular rib 402, so that when the annular rib 402 is embedded in the limiting ring groove 301, the limiting ring groove 301 is slightly deformed, so that the annular rib 402 and the limiting ring groove 301 have a strong tightness, thereby further enhancing the stability between the spring pad and the empty spring lower seat 4.

[0054] Furthermore, the limiting portion 3 further includes a limiting groove 302, which is specifically a rectangular groove. The limiting groove 302 extends along the radial direction of the first surface 103, one end of the limiting groove 302 extends to the inner ring 101 of the main body 1, and the other end of the limiting groove 302 extends to the outer ring 102 of the main body 1. The reinforcing rib also includes a strip rib 403 arranged on the mounting surface of the empty spring lower seat 4, the shape of the limiting groove 302 is adapted to the shape of the strip rib 403, so that the strip rib 403 can be embedded in the limiting groove 302, preferably, the number of the limiting grooves 302 and the number of the strip rib 403 are both multiple, and the two are the same and one-to-one corresponding, the multiple limiting grooves 302 are centrally symmetrically arranged along the circle of the inner ring 101 of the main body 1, and each strip rib 403 is embedded in a limiting groove 302.

[0055] The diameter of the limiting groove 302 is the same as the diameter of the strip rib 403, and the width of the limiting groove 302 is the same as the thickness of the strip rib 403, so that the annular groove can be embedded in the limiting groove 302. Preferably, the width of the limiting groove 302 is slightly smaller than the thickness of the strip rib 403, so that when the strip rib 403 is embedded in the limiting groove 302, the limiting groove 302 is slightly deformed, so that there is a strong tightness between the strip rib 403 and the limiting groove 302, further enhancing the stability between the spring pad and the empty spring lower seat 4.

[0056] It should be noted that the limiting ring groove 301 and the limiting groove 302 on the first surface 103 of the main body 1 extend in different directions, and each limiting groove 302 is connected to the limiting ring groove 301 to avoid interference with the intersection position of the annular rib 402 and the strip rib 403, thereby avoiding affecting the flatness of the spring pad when assembled between the empty spring lower seat 4 and the lower swing arm 5.

[0057] A plurality of limiting ring grooves 301 and a plurality of limiting grooves 302 are staggeredly distributed on the first surface 103 of the main body 1, which significantly enhance the stability between the spring pad and the empty spring lower seat 4, so that during the operation of the air spring, the spring pad can move synchronously with the empty spring lower seat 4, and the limiting ring grooves 301 and the limiting grooves 302 have interaction forces with the empty spring lower seat 4 in different directions, which can effectively prevent the spring pad from rotating relative to the empty spring lower seat 4, thereby preventing the spring pad from shifting or even falling off between the empty spring lower seat 4 and the lower swing arm 5, and furthermore, can play the role of a gasket separator between the empty spring lower seat 4 and the lower swing arm 5 for a long time, preventing the empty spring lower seat 4 from directly contacting and moving relative to the lower swing arm 5, causing abnormal noise and wear, and affecting the overall life of the air spring.

[0058] Furthermore, an embedding portion 105 is defined between two adjacent limiting grooves 302, and the annular groove passes through each embedding portion 105, or in other words, the annular groove divides each embedding portion 105 into two parts distributed radially along the first surface 103, and the shape of the embedding portion 105 is adapted to the cavity defined by the annular rib 402 and the strip rib 403 on the empty spring seat 4. After the spring pad is assembled between the empty spring seat 4 and the lower swing arm 5, the embedding portion 105 can be respectively embedded in the multiple cavities formed by the empty spring seat 4, which on the one hand strengthens the limiting effect between the spring pad and the empty spring seat 4, and on the other hand avoids the spring pad from occupying too much space between the empty spring seat 4 and the lower swing arm 5 in the thickness direction thereof.

[0059] Preferably, the spring pad is made of polyurethane material. Specifically, the main body 1 and the extension part 2 have an integrated structure, and are both made of polyurethane material through integral processing. They are not only elastic, but also can play a lubricating role, avoiding rigid contact with the empty spring seat 4 and the lower swing arm 5 and causing damage to the empty spring seat 4 and / or the lower swing arm 5.

[0060] Furthermore, the spring washer also includes a clamping portion 201, which is specifically a groove body formed by the extension portion 2 being recessed along its radial direction toward the outside of the extension portion 2, and the length of the clamping portion 201 extends along the axial direction of the extension portion 2. A convex portion 404 is formed on the outer surface of the side wall of the central fixing cylinder 401 of the empty spring lower seat 4, and the shape of the clamping portion 201 is adapted to the shape of the convex portion 404. When the spring washer is assembled to the empty spring lower seat 4, the clamping portion 201 can be aligned with the convex portion 404, at which time the limiting annular groove 301 is just aligned with the annular rib 402, and the multiple strip ribs 403 are just corresponding to the multiple limiting grooves 302. It can be seen that by providing the clamping portion 201 on the main body 1, it can play a fool-proof role during assembly, reduce assembly difficulty, and improve assembly efficiency.

[0061] In addition, after the spring washer is assembled to the empty spring seat 4, the clamping portion 201 and the protrusion 404 are adapted and clamped to each other, which can play an anti-rotation role between the extension portion 2 of the spring washer and the central fixed tube 401, and further enhance the stability between the spring washer and the empty spring seat 4.

[0062] Furthermore, the empty spring lower seat 4 is provided with a fixing hole for inserting a fastener 405, wherein the fastener 405 here can be specifically but not limited to a fixing pin, and the empty spring lower seat 4 is fixed to the lower swing arm 5 and the vehicle body using the air spring in this embodiment through the fixing pin. The main body 1 is provided with an avoidance portion 106, which is specifically a notch formed on the edge of the outer ring 102 of the main body 1. When the fixing pin is used to connect the empty spring lower seat 4, the lower swing arm 5 and the vehicle body, the avoidance portion 106 just avoids the fixing pin to avoid interference with the fixing pin, thereby affecting the connection of the fixing pin to the empty spring lower seat 4, the lower swing arm 5 and the vehicle body, and the flatness of the spring pad between the empty spring lower seat 4 and the lower swing arm 5. Alternatively, the avoidance portion 106 can also be an avoidance hole on the main body 1 for inserting a fixing pin. Regardless of whether the avoidance portion 106 is a notch on the outer ring 102 of the main body 1 or a through hole penetrating the first surface 103 and the second surface 104 of the main body 1, after the fixing pin is connected, the avoidance portion 106 can be mutually engaged with the fixing pin, thereby further enhancing the stability of the spring pad between the empty spring lower seat 4 and the lower swing arm 5.

[0063] It should be noted that there are multiple fixing pins, and the shape of the avoidance portion 106 is the same as the number of the fixing pins and is arranged in a one-to-one correspondence.

[0064] To sum up, the spring pad provided in the present application can separate the air spring and the designated position of the vehicle body for connecting with the air spring at the mounting surface, and can effectively ensure the stability between the air spring and the mounting surface, significantly reducing the risk of displacement and falling off of the spring pad, thereby avoiding the air spring being worn due to rigid contact with the designated position of the vehicle body during vehicle driving, affecting the service life of the air spring, and avoiding abnormal noise at the location of the air spring.

[0065] The embodiments of the present application also provide a vehicle, including the spring pad described in the above embodiments, and thus having all the beneficial technical effects of the spring pad, which will not be described in detail herein.

[0066] The vehicle also includes a vehicle body, an air spring and a lower swing arm 5, wherein the air spring includes an empty spring upper seat and an empty spring lower seat 4, the empty spring upper seat is connected to a designated position of the vehicle body, the empty spring lower seat 4 is connected to the lower swing arm 5, and the lower swing arm 5 is also connected to another designated position of the vehicle body, the above-mentioned spring pad is arranged on the empty spring upper seat and is located between the empty spring upper seat and a designated position of the vehicle body, or, as described above, the spring pad is arranged on the empty spring lower seat 4 and is located between the empty spring lower seat 4 and the lower swing arm 5.

[0067] Of course, according to actual needs, a spring pad can be arranged between the empty spring upper seat and the vehicle body, and between the empty spring lower seat 4 and the lower swing arm 5 respectively.

[0068] To sum up, the vehicle provided in the present application includes the spring pad described above. Therefore, the spring pad can effectively avoid the rigid contact between the air spring and the vehicle body or the air spring and the lower arm 5 to produce abnormal noise, or cause damage to the air spring, the vehicle body or the lower arm 5, increase the vehicle failure rate, and affect driving safety.
