[0033] The stabilizer bar is an auxiliary elastic element in the automobile suspension, mainly to prevent the lateral roll of the vehicle body when turning, and to improve the comfort of the vehicle, which is an important structure in the automobile chassis connecting pair. The stabilizer bar is a torsion bar spring made of spring steel, the middle part of the rod body is hinged with the vehicle body or frame through a clamp, and the two ends of the rod are fixed on the left and right suspensions respectively. The connecting rod connects the stabilizer bar and the suspension, and is fixed on the stabilizer bar flatted hole and other parts of the suspension. At present, the connection between the automobile stabilizer bar and the connecting rod is mainly assembled with ball pin, the connecting rod ball pin is inserted through the stabilizer bar mounting hole, and then the ball pin and the stabilizer bar are locked with a nut. However, the stabilizer bar connecting rod connection structure in the prior art has low machining precision of the stabilizer bar, and there is a gap between the stabilizer bar and the connecting rod, which is easy to produce abnormal sound during relative movement.

[0034] In view of this, the stabilizer bar and connecting rod connection structure and vehicle provided in the embodiments of the present invention, by providing a connecting portion on the stabilizer bar, the connecting portion having a stepped hole, the stepped hole including a first support section and a second support section coaxially arranged; the connecting rod assembly including a connecting rod and a connecting rod washer sleeved on the connecting rod, the connecting rod being inserted into the connecting portion via the first and second support sections; the side of the connecting rod washer being conical, the small-diameter end of the connecting rod washer facing the first support section, the connecting rod washer being partially embedded in the first support section, and the inner sidewall of the first support section being conical to match the side of the connecting rod washer. This compensates for the gap between the stabilizer bar and the connecting rod, thereby reducing abnormal noise generated by the relative movement of the stabilizer bar and the connecting rod.

[0035] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0036] Figure 1 This is a structural diagram of the connection structure between the stabilizer bar and the connecting bar provided in an embodiment of the present invention.

[0037] Reference Figure 1 The present invention provides a connection structure for a stabilizer bar and a connecting bar, comprising a stabilizer bar 100 and a connecting bar assembly 200. The stabilizer bar 100 is provided with a connecting portion 110, and the connecting portion 110 is provided with a stepped hole 120, the stepped hole 120 including a first support section 121 and a second support section 122 coaxially arranged; the connecting bar assembly 200 includes a connecting bar 210 and a connecting bar washer 220 sleeved on the connecting bar 210, the connecting bar 210 being inserted into the connecting portion 110 via the first support section 121 and the second support section 122; the side of the connecting bar washer 220 is conical, the small diameter end of the connecting bar washer 220 faces the first support section 121, the connecting bar washer 220 is partially embedded in the first support section 121, and the inner sidewall of the first support section 121 is conical to match the side of the connecting bar washer 220.

[0038] The stabilizer bar 100, also known as an anti-roll bar, is an auxiliary elastic element in the automotive suspension. When the vehicle body tilts, the longitudinal portions on both sides of the stabilizer bar 100 deflect in different directions, causing the stabilizer bar 100 to twist and the side arms to bend. This increases the angular stiffness of the suspension, reduces the degree of lateral roll, and improves the ride comfort.

[0039] The main component of the stabilizer bar 100 is spring steel, which has high hardness.

[0040] Figure 2 for Figure 1 A schematic diagram of the stabilizer bar. (See reference.) Figure 2The connecting portion 110 is arranged on the stabilizer bar 100, and is flat in optional design, so as to facilitate the fixed connection of the connecting rod assembly 200 and the stabilizer bar 100. In the application, the stepped hole 120 arranged on the connecting portion 110 is a through hole, and the stepped hole 120 comprises a first supporting section 121 and a second supporting section 122. The first supporting section 121 is conical, and the inner diameter of the end close to the second supporting section 122 is small, and the inner diameter of the end far from the second supporting section 122 is large. The second supporting section 122 is a circular hole, and the inner diameter of the second supporting section 122 is smaller than the small diameter of the first supporting section 121, so that the first supporting section 121 has an inner bottom wall.

[0041] The inner diameter of the second supporting section 122 matches the diameter of the connecting rod 210, so that the connecting rod 210 passes through the second supporting section 122.

[0042] In the specific implementation, the process of manufacturing the stabilizer bar 100 does not need to be changed, and only the punching die needs to be modified to realize the production of the stabilizer bar 100. The improvement of the stabilizer bar 100 is realized, and the production difficulty is not increased.

[0043] The connecting rod assembly 200 comprises the connecting rod 210, and the connecting rod 210 belongs to a two-force bar system component. The loads at both ends are transmitted through the middle rod body.

[0044] The connecting rod 210 is inserted into the connecting portion 110 through the first supporting section 121 and the second supporting section 122, so as to realize the connection of the connecting rod 210 and the stabilizer bar 100. Thus, the connection structure of the stabilizer bar 100 and the connecting rod 210 can realize the purpose of reducing the degree of lateral roll of the automobile and improving the riding comfort of the automobile.

[0045] The connecting rod gasket 220 is sleeved on the connecting rod 210, that is, the inner diameter of the connecting rod gasket 220 matches the diameter of the connecting rod 210, so that the connecting rod gasket 220 is sleeved on the connecting rod 210.

[0046] Specifically, the side surface of the connecting rod gasket 220 is conical, the side surface of the connecting rod gasket 220 matches the conical shape of the inner side wall of the first supporting section 121, the small-diameter end of the connecting rod gasket 220 faces the first supporting section 121, so that the connecting rod gasket 220 is partially embedded in the first supporting section 121. The side surface of the connecting rod gasket 220 and the inner side wall of the first supporting section 121 are conical, which can effectively prevent the connecting rod 210 from sliding in the stepped hole 120 of the stabilizer bar 100, so as to realize the purpose of reducing the abnormal sound generated by the relative movement of the stabilizer bar 100 and the connecting rod 210.

[0047] The connecting structure of the stabilizing rod and the connecting rod provided by the embodiment of the present application comprises a connecting portion 110 arranged on the stabilizing rod 100, the connecting portion 110 is provided with a stepped hole 120, the stepped hole 120 comprises a first supporting section 121 and a second supporting section 122 arranged coaxially; a connecting rod assembly 200 comprises a connecting rod 210 and a connecting rod gasket 220 sleeved on the connecting rod 210, the connecting rod 210 is inserted into the connecting portion 110 through the first supporting section 121 and the second supporting section 122; the side surface of the connecting rod gasket 220 is conical, the small-diameter end of the connecting rod gasket 220 faces the first supporting section 121, the connecting rod gasket 220 is partially embedded in the first supporting section 121, and the inner side wall of the first supporting section 121 is conical and matches the side surface of the connecting rod gasket 220. The gap between the stabilizing rod 100 and the connecting rod 210 is offset, so that the abnormal sound generated by the relative movement of the stabilizing rod 100 and the connecting rod 210 is eliminated.

[0048] Referring to Figures 1 to 5 In the embodiment of the present application, the connecting structure of the stabilizing rod 100 and the connecting rod 210 further comprises a gasket 300, the gasket 300 is sleeved on the connecting rod gasket 220, and the gasket 300 is partially embedded in the first supporting section 121 and abuts between the outer side wall of the connecting rod gasket 220 and the inner side wall of the first supporting section 121.

[0049] The gasket 300 is annular, the number of the gasket 300 is one, and the gasket 300 is sleeved on the connecting rod gasket 220. During the process of partially embedding the connecting rod gasket 220 in the first supporting section 121, the gasket 300 sleeved on the connecting rod gasket 220 is partially embedded in the first supporting section 121 together with the connecting rod gasket 220, so that the gasket 300 abuts between the outer side wall of the connecting rod gasket 220 and the inner side wall of the first supporting section 121.

[0050] In the process of connecting the connecting rod gasket 220 and the first supporting section 121, the gap caused by the insufficient machining precision in the production process can be solved by sleeving the gasket 300 on the connecting rod gasket 220.

[0051] In the embodiment of the present application, the gasket 300 is conical, the outer side wall of part of the gasket 300 is in interference fit with the inner side wall of the first supporting section 121, and the inner side wall of part of the gasket 300 is in interference fit with the outer side wall of the connecting rod gasket 220.

[0052] Figure 5 For Figure 1 the schematic view of the gasket structure. Referring to Figure 5The gasket 300 is conical, the gasket 300 is sleeved on the large-diameter inner diameter of one end of the connecting rod gasket 220, the gasket 300 is sleeved on the small-diameter inner diameter of one end of the connecting rod gasket 220, the inner side wall of part of the gasket 300 is in interference fit with the outer side wall of the connecting rod gasket 220, and the purpose is to firmly sleeve part of the gasket 300 on the connecting rod gasket 220, so that the gasket 300 is prevented from slipping off.

[0053] The outer side wall of part of the gasket 300 is in interference fit with the inner side wall of the first support section 121, so that the connecting rod gasket 220 and the first support section 121 are tightly connected. In this way, the gap caused by the machining precision problem can be avoided, and the connecting rod gasket 220 is prevented from loosening in the first support section 121.

[0054] In the embodiment of the application, the gasket 300 is a plastic gasket.

[0055] Optionally, the gasket 300 is made of plastic material. The plastic material is chemically stable and will not rust, has good impact resistance and good wear resistance. In addition, the plastic material has the advantages of good formability and low processing cost. Of course, the gasket 300 can also be made of rubber or other materials that can achieve the same effect. The purpose is to offset the gap between the connecting rod gasket 220 and the first support section 121.

[0056] The gasket 300 is abutted between the outer side wall of the connecting rod gasket 220 and the inner side wall of the first support section 121, which can effectively eliminate the abnormal sound between the connecting rod 210 and the stabilizing rod 100 during movement. The gasket 300 has the functions of non-metal locking and anti-loosening.

[0057] In specific implementation, the gasket 300 can play a buffering role, so that the connecting rod gasket 220 and the first support section 121 can be prevented from directly rubbing during use. It can be understood that the service life of the stabilizing rod 100, the connecting rod 210 and the connecting rod gasket 220 can be effectively improved by arranging the gasket 300.

[0058] In the embodiment of the application, the connecting rod 210 is provided with a stop ring 211, and the connecting rod gasket 220 is abutted between the stop ring 211 and the first support section 121. The connecting rod assembly 200 further comprises a nut 230, the connecting rod 210 has an external thread, the nut 230 is sleeved on the external thread, and the nut 230 is abutted against the side of the connecting part 110 away from the connecting rod gasket 220, so as to jointly and fixedly connect the stabilizing rod 100 and the connecting rod 210 with the connecting rod gasket 220 and the stop ring 211.

[0059] Figure 3 For Figure 1 the connecting rod structure schematic view. Referring to Figure 3Optionally, the connecting rod 210 and the stop ring 211 are integrally formed, thereby facilitating the machining of the connecting rod 210 and the stop ring 211 and facilitating the fixed connection of the connecting rod 210 and the stabilizer bar 100.

The threaded connection is a widely used detachable fixed connection, and the threaded connection has the advantages of simple structure, reliable connection and convenient disassembly and assembly.

[0062] Specifically, the nut 230 is in abutment with the side of the connecting portion 110 away from the connecting rod pad 220 and is sleeved on the female thread of the connecting rod 210. One end of the connecting rod 210 is limited by the stop ring 211, and the other end of the connecting rod 210 is limited by the threaded connection, thereby achieving the fixed connection between the connecting rod pad 220, the stabilizer bar 100 and the connecting rod 210.

The hexagonal flange nut is used for the nut 230, has a large contact area with the stabilizer bar 100 and can also play a role in preventing loosening. Of course, the nut 230 can also be other nuts that can play a locking role, as long as the stabilizer bar 100 and the connecting rod 210 can be fixedly connected, and the present embodiment is not limited in this regard.

[0064] In the embodiment of the present application, the first support section 121 has an inner bottom wall, and the end face of the connecting rod pad 220 facing the inner bottom wall is in abutment with the inner bottom wall.

[0068] In the embodiment of the present application, the anti-skid part 221 comprises a plurality of anti-skid rings with the same center.

[0069] Optionally, the anti-skid rings on the anti-skid part 221 are made of a material with high hardness, so as to facilitate the inlaying of the anti-skid part 221 in the interior of the stabilizer bar 100. That is, the connecting rod gasket 220 can be made of a material with higher hardness than the stabilizer bar 100, so as to smoothly inlay the anti-skid part 221 in the interior of the stabilizer bar 100. The anti-skid rings of the anti-skid part 221 are provided in a plurality, and the specific number is not limited in the embodiment, which aims to increase the anti-skid ability.
