Description

Technical Field

[0001] The utility model relates to the technical field of automobiles, in particular to a support arm structure for an automobile chassis suspension. Background Art

[0002] Whether it is a modified or original car assembly, the wheels must be fixed, which is also called four-wheel alignment. Four-wheel alignment requires special testing instruments to determine the difference between the various angles of the four wheels and the original design and factory adjustment values. Special parts or tools are then used to adjust and correct them to the original design and factory adjustment values or within the tolerance range. The whole process of four-wheel alignment requires the design of various angles of the car's four wheels to ensure the smoothness, safety and comfort of the car's driving. Four-wheel alignment can ensure that the car will not run off the track, drift, side slip, unstable steering, uneven tire wear, and increased wear of suspension system parts.

[0003] The support arm structures used in existing original vehicle models are formed by pressing a single piece of steel plate or integrally forging from a forging. These support arms are fixed, non-adjustable structures and lack versatility and adjustability. For the reasons mentioned above, when a problem occurs with the inward or outward tilt of the upper edge of the wheel camber angle, that is, when adjusting the vehicle load, the force point must be applied to the center of the tire to eliminate deviation and reduce tire wear.

[0004] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

[0026] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the embodiments described are some embodiments of the present invention, not all embodiments.

[0027] In the description of the present invention, it should be understood that the terms "center", "transverse", "longitudinal", "front", "back", "left", "right", "up", "down", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the scope of protection of the present invention. When a component is referred to as being "fixed to" another component, it may be directly on the other component or there may also be a centered component. When a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centered component at the same time. When a component is considered to be "set on" another component, it may be directly set on the other component or there may be a centered component at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0028] like Figures 1 to 7As shown, the utility model is an arm structure for a chassis suspension of an automobile, comprising: a curved connector 1, a mounting groove provided on the curved connector 1, a plug-in column 2 slidably installed in the mounting groove, a connecting column 3 fixedly installed at the end of the plug-in column 2, a rubber sleeve mounting ring 4 fixedly installed at the end of the connecting column 3, and an adjusting mechanism for adjusting the overall length of the plug-in column 2 and the curved connector 1; the adjusting mechanism comprises: a fastening bolt 5 threadedly connected to the curved connector 1, a plug-in hole (not shown) provided on the plug-in column 2, a protective component for protecting the fastening bolt 5, and an anti-loosening component for preventing the fastening bolt 5 from loosening.

[0029] When it is necessary to adjust the overall length of the plug-in column 2 and the curved connector 1, the plug-in column 2 is slid in the installation groove to facilitate the adjustment of the overall length of the plug-in column 2 and the curved connector 1. After the adjustment is completed, the fastening bolt 5 is tightened so that the fastening bolt 5 is inserted into the corresponding plug-in hole cavity, thereby fixing the overall length of the adjusted plug-in column 2 and the curved connector 1. Therefore, the support arm structure in this application is convenient for length adjustment and has good versatility and adjustability.

[0030] Since the fastening bolt 5 is directly exposed to the outside, external stains are easily attached to the fastening bolt 5 and corrode the fastening bolt 5 , which not only makes it inconvenient to subsequently disassemble the fastening bolt 5 , but also reduces the service life of the fastening bolt 5 .

[0031] The protective assembly includes: a protective shell 6 mounted on the fastening bolt 5, a handle 7 fixedly mounted on the protective shell 6, and a reset unit for driving the protective shell 6 to reset; the reset unit includes: a limiting rod 9 fixedly mounted on the curved connecting member 1, a movable plate 8 mounted on the limiting rod 9, and a reset spring 10 for driving the protective shell 6 to reset; the movable plate 8 is fixedly connected to the protective shell 6; one end of the reset spring 10 is fixedly connected to the movable plate 8, and the other end of the reset spring 10 is fixedly connected to the limiting rod 9.

[0032] When it is necessary to tighten the fastening bolt 5, the handle 7 is pulled upward to drive the protective shell 6 to move upward, so that the protective shell 6 no longer has a sealing effect on the fastening bolt 5. At this time, the fastening bolt 5 can be tightened by a tool. In the process of the protective shell 6 moving upward, the movable plate 8 can be driven to move upward, and the movable plate 8 drives the return spring 10 to deform.

[0033] When the fastening bolt 5 is tightened, the handle 7 is loosened, and the elastic force of the reset spring 10 drives the movable plate 8 to reset downward, thereby driving the protective shell 6 to reset downward, so that the protective shell 6 closes the fastening bolt 5 again.

[0034] By setting up the protective component, the fastening bolt 5 can be sealed after being tightened, thereby playing a role of anti-fouling protection and avoiding the fastening bolt 5 being directly exposed to the outside, and external stains easily adhering to the fastening bolt 5 and causing corrosion to the fastening bolt 5.

[0035] Since the car will generate vibration during driving, which will drive the fastening bolt 5 to vibrate, if it is subjected to vibration for a long time, the fastening bolt 5 will become loose, thereby reducing the fixing effect of the plug-in column 2 and the bent connector 1, thereby affecting the stability of the support arm structure and causing safety hazards.

[0036] The anti-loosening component includes: a locking plate 15, the shape of the locking plate 15 matches the fastening bolt 5, a linkage unit that drives the locking plate 15 to move, and a limiting unit that limits the locking plate 15 when it moves; the linkage unit includes: a mounting bracket 14 fixedly mounted on the curved connector 1, a linkage gear 12 rotatably mounted on the mounting bracket 14, a rack 11 and a rack 2 13 meshing with the linkage gear 12; the rack 11 is fixedly connected to the protective shell 6; the rack 2 13 is fixedly connected to the locking plate 15; the limiting unit includes: a slide groove provided on the curved connector 1, a slider 16 slidably mounted in the slide groove, and a fixing rod 17 for positioning the slider 16; the slider 16 is fixedly connected to the locking plate 15; both ends of the fixing rod 17 are fixedly mounted on the inner wall of the slide groove.

[0037] When the protective shell 6 moves upward, it can drive the rack 11 to move, the rack 11 drives the connecting gear 12 to rotate, the connecting gear 12 drives the rack 2 13 to move, and the rack 2 13 drives the clamping plate 15 to move, so that the clamping plate 15 is separated from the fastening bolt 5, and the clamping plate 15 no longer has a limiting effect on the fastening bolt 5, which makes it convenient to install or remove the fastening bolt 5.

[0038] When the fastening bolt 5 is tightened, the protective shell 6 is reset downward and drives the rack 11 to move downward. The rack 11 drives the linkage gear 12 to rotate in the opposite direction, thereby driving the rack 2 13 to move. The rack 2 13 drives the clamping plate 15 to abut against the fastening bolt 5. At this time, the clamping plate 15 limits the fastening bolt 5, avoiding the problem of the fastening bolt 5 being loosened due to vibration, thereby ensuring the stability of the support arm structure.

[0039] Working principle: When in use, the plug-in column 2 is slid in the installation groove to facilitate the adjustment of the overall length of the plug-in column 2 and the curved connector 1. After the adjustment is completed, the fastening bolt 5 is tightened so that the fastening bolt 5 is inserted into the corresponding plug-in hole cavity, thereby fixing the overall length of the adjusted plug-in column 2 and the curved connector 1. Therefore, the support arm structure in this application is convenient for length adjustment and has good versatility and adjustability.
