Description

Technical Field

[0001] The utility model relates to the technical field of anti-roll bars, in particular to a corrosion-resistant lightweight rear roll bar for a car. Background Art

[0002] The anti-roll bar is an important component of the independent suspension system and air suspension system of the automobile. It is mainly used in buses, trucks, cars, new energy vehicles and other vehicles. It is installed at the front and rear ends of the chassis, connecting the left and right suspensions. The shape is generally "U". When the body only moves vertically, the deformation of the suspensions on both sides is the same, and the anti-roll bar does not work. When the body rolls, the suspensions on both sides jump inconsistently, the anti-roll bar twists, and the elastic force of the rod body becomes a resistance to continued roll, playing the role of an anti-roll bar.

[0003] When in use, the existing rear anti-roll bar of a car is usually connected to the suspension on the left and right sides of the vehicle by bolts. However, the existing anti-roll bar lacks an effective locking structure when connected to the suspension, which leads to the bolts being easily loosened when subjected to more severe vibration impact, causing the anti-roll bar to be disconnected from the suspension or produce abnormal noise, posing a major safety hazard and making it difficult to meet usage requirements. Utility Model Content

[0004] The purpose of the utility model is to solve the problem in the prior art that the anti-roll bar lacks an effective locking structure when connected to the suspension, which leads to the bolts being easily loosened when subjected to more severe vibration impact, the anti-roll bar being disconnected from the suspension or producing abnormal noise, posing a great safety hazard and being difficult to meet the use requirements, and a corrosion-resistant lightweight rear sway bar for a car is proposed.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a corrosion-resistant lightweight rear roll bar for a car, including an anti-roll bar, both ends of the anti-roll bar are connected to connecting rods, one end of the connecting rod is fixedly connected to two fixing frames on the outside, a locking assembly is arranged on the top of a single fixing frame, a handwheel is arranged on the top of the locking assembly, one end of the handwheel movably passes through the locking assembly and the single fixing frame and is connected to a screw rod, and a limiting ring frame is arranged on the outside of the screw rod.

[0006] Preferably, a plurality of eight-way brackets are arranged on the inner side of the anti-roll bar, a fixing rod is fixedly connected between the plurality of eight-way brackets, and a zinc coating is arranged on the outer side of the anti-roll bar.

[0009] Preferably, a connecting seat is provided at one end of the connecting rod, a connecting bolt is installed on the inner side of the connecting seat, and the limiting ring frame is sleeved on the outer side of the connecting bolt.

[0010] Preferably, one end of each of the two connecting rods is provided with a connecting flange, and the connecting rod is fixedly connected to the anti-roll bar via the connecting flange.

[0011] Preferably, a rubber bushing is sleeved on the outer side of the connecting rod, a mounting seat is arranged on the top of the rubber bushing, and screw holes are penetrated through the four corners of the top of the mounting seat.

[0012] Preferably, the diameter of the anti-roll bar is 3 cm, and the wall thickness of the anti-roll bar is 1 cm.

[0013] Compared with the prior art, the advantages and positive effects of the utility model are:

[0014] 1. In the utility model, by turning the hand wheel, the screw rod is driven to rotate, causing the limit ring frame to slide on the screw rod. When the limit ring frame rises, an upward pulling force is generated on the connecting bolt, thereby limiting it, thereby improving the connection strength between the anti-roll bar and the suspension, effectively improving the connection stability, preventing the connecting bolt from loosening, avoiding safety hazards, and meeting actual use needs.

[0015] 2. In the utility model, the eight-way bracket is used to support the inside of the anti-roll bar, thereby reducing the weight of the anti-roll bar, while ensuring that the strength of the anti-roll bar itself remains unchanged. The zinc coating can provide cathodic protection for the anti-roll bar, thereby improving the corrosion resistance of the anti-roll bar and extending its service life.

However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] Example 1: Figure 1-Figure 4 As shown, the utility model provides a technical solution: a corrosion-resistant lightweight rear roll bar for a car, comprising an anti-roll bar 1, both ends of the anti-roll bar 1 are connected to a connecting rod 2, one end of the connecting rod 2 is fixedly connected to two fixing frames 3 on the outside, a locking assembly is arranged on the top of a single fixing frame 3, a hand wheel 4 is arranged on the top of the locking assembly, one end of the hand wheel 4 movably passes through the locking assembly and the single fixing frame 3 and is connected to a screw rod 5, and a limiting ring frame 6 is arranged on the outside of the screw rod 5.

[0024] In this embodiment, by turning the hand wheel 4, the screw rod 5 is driven to rotate, causing the limiting ring frame 6 to slide on the screw rod 5. When the limiting ring frame 6 rises, an upward pulling force is generated on the connecting bolt 18, thereby limiting it, thereby improving the connection strength between the anti-roll bar 1 and the suspension, effectively improving the connection stability, preventing the connecting bolt 18 from loosening, avoiding safety hazards, and meeting actual use needs.

[0025] Example 2: Figure 1-Figure 4As shown, a plurality of eight-way brackets 7 are arranged on the inner side of the anti-roll bar 1, and a fixing rod 8 is fixedly connected between the plurality of eight-way brackets 7.
