Description

Technical Field

[0001] The present invention belongs to the technical field of wheel control arms, and mainly relates to a connection structure between a connecting member of a U-shaped arm and a ball head assembly. Background Art

[0002] When an automobile leaves the factory, its wheels, steering mechanism, front and rear axles, etc. all have set fixed positions and angles, which are to ensure the smoothness, safety and comfort of the vehicle during driving. After a period of driving, under the influence of long-term stress or accident collision, etc., these position and angle data will deviate from the set values at the time of leaving the factory. At this time, phenomena such as vehicle pulling to one side, floating, side slipping, unstable steering, uneven tire wear, and increased wear of suspension system parts will occur.

[0003] For vehicles of the double-wishbone suspension type, the upper control arm of the suspension is generally a U-shaped integral structure formed by stamping or forging. Since the position of the bushing on the vehicle is fixed and unchanged, it can be obtained from simple triangular geometric relationships that when adjusting the wheel angle, the included angle between the two connecting members will inevitably change. However, the existing U-shaped arm is an integral stamping structure and cannot adjust the angle of the U-shaped arm, which cannot meet the market demand. Summary of the Invention

[0004] In order to overcome the above deficiencies, the present invention provides a connection structure between a connecting member of a U-shaped arm and a ball head assembly.

[0005] The technical solution adopted by the present invention to solve its technical problems is as follows:

[0006] A connection structure between a connecting member of a U-shaped arm and a ball head assembly, comprising

[0007] A first connecting member, one end of the first connecting member has a ball head assembly, and the ball head shell of the ball head assembly and the first connecting member are of an integral structure;

[0008] A second connecting member, one end of the second connecting member has an upper mounting ring;

[0009] A locking structure, located on the second connecting member, comprising:

[0010] A locking groove, the locking groove is arranged along the length direction of the second connecting member body and communicates with the upper mounting ring;

[0011] A threaded hole, the threaded hole is arranged on the side part of the second connecting member body and communicates with the locking groove;

[0012] A limiting connecting plate, one end has a through hole, and this end is located in the locking groove, and the other end has a pressing part;

[0013] The side locking bolt is located in the threaded hole and is used to lock the upper mounting ring of the second connecting member and the limit connecting plate;

[0014] Among them, the upper mounting ring of the second connecting member is sleeved on the ball head shell from the upper end of the ball head pin. After the dust cover of the ball head assembly is sleeved on the ball head pin, it is buckled between the inner side of the upper mounting ring and the outer side of the ball head shell; the side locking bolt passes through the through hole of the limit connecting plate, and the pressing portion abuts against the base of the ball head shell; the limit connecting plate and the upper mounting ring of the second connecting member are fixed by the side locking bolt.

[0015] The pressing portion of the limit connecting plate is a C-shaped fork and can be stuck on the base of the ball head shell.

[0016] Both the first connecting member and the second connecting member have telescopic structures.

[0017] The telescopic structure is a combined structure of a screw sleeve and a screw rod.

[0018] Due to the adoption of the above-mentioned technical solutions, the present invention has the following advantages:

[0019] A connection structure between a U-shaped arm connecting member and a ball head assembly provided by the present invention enables the second connecting member to rotate relative to the ball head assembly. By adjusting the length of the telescopic structure, the wheel angle can be adjusted, solving the problem that the original vehicle U-shaped arm cannot adjust the wheel angle.

[0024] To make the objectives, 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 in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Usually, the components of the embodiments of the present invention described and illustrated herein can be arranged and designed in various different configurations.

[0025] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0026] A connection structure between a connecting member and a ball head assembly of a U-shaped arm as described in conjunction with the accompanying drawings includes

[0027] a first connecting member 2, a second connecting member 3, a locking structure, and a ball head assembly 1;

[0028] As Figure 2 shown, one end of the first connecting member 2 has a ball head assembly 1, and the ball head shell 7 of the ball head assembly 1 is an integral structure with the first connecting member 2;

[0029] One end of the second connecting member 3 has an upper mounting ring 5;

[0030] The locking structure is located on the second connecting member 3 and includes: a locking groove 4, a threaded hole, a limiting connecting plate 8, and a side locking bolt 9; the locking groove 4 is arranged along the length direction of the body of the second connecting member 3 and is communicated with the upper mounting ring 5; the locking groove 4 penetrates through the upper and lower surfaces of the second connecting member 3; the threaded hole is arranged on the side part of the body of the second connecting member 3 and is communicated with the locking groove 4; one end of the limiting connecting plate 9 has a through hole, and this end is located in the locking groove 4, and the other end has a pressing part; the side locking bolt 9 is located in the threaded hole and is used to lock the upper mounting ring 5 of the second connecting member 3 and the limiting connecting plate 8; when the inclination angle needs to be adjusted, only need to loosen the side locking bolt 9 to make the inner diameter of the upper mounting ring 5 larger, so that the two connecting members can rotate freely, and then by adjusting the length of the telescopic structure, the wheel angle can be adjusted.

[0031] The upper mounting ring 5 of the second connecting member 3 is sleeved on the ball head shell 7 from the upper end of the ball head pin 11, and after the dust cover 10 is sleeved on the ball head pin 11, it is buckled between the inner side of the upper mounting ring 5 and the outer side of the ball head shell 7; the side locking bolt 9 passes through the through hole of the limiting connecting plate 8, and the pressing part abuts against the base of the ball head shell 7; the limiting connecting plate 8 and the upper mounting ring 5 of the second connecting member 3 are fixed by the side locking bolt 9.

[0032] The pressing part of the limiting connecting plate 8 is a C-shaped fork and can be stuck on the base of the ball head shell 7.

[0033] Both the first connecting member 2 and the second connecting member 3 have telescopic structures.

[0034] The telescopic structure is a combined structure of a screw sleeve and a screw rod. The combination of the screw sleeve and the screw rod is a prior art and will not be elaborated here.

[0035] During installation, the upper mounting ring 5 of the second connecting member 3 is sleeved outside the ball head housing 7 after passing through the ball head pin 11. The lower end of the dust cover 10 is installed at the gap between the two connecting members. One end of the limit connecting plate 8 with a through hole is placed into the locking groove 4, and the through hole is aligned with the threaded hole. The side locking bolt 9 passes through the through hole, and the C-shaped fork of the limit connecting plate abuts against the base of the ball head housing 7. As the side locking bolt 9 is screwed, the gap of the locking groove 4 becomes smaller and smaller, clamping the limit connecting plate 8, thereby realizing the fixation of the base. At the same time, the inner diameter of the upper mounting ring 5 also becomes smaller and smaller, and the fixed connection between the first connecting member 2 and the second connecting member 3 is also realized.

[0036] By adjusting the length of the telescopic structure, the relative position of the ball head assembly 1 relative to the bushing is changed, thereby pushing or pulling the movement of the wheel knuckle to adjust the wheel angle, solving the problem that the original vehicle U-shaped arm cannot adjust the wheel angle.

[0037] Since the position of the bushing on the vehicle is fixed, it can be obtained from simple triangle geometric relationships that when adjusting the wheel angle, the included angle between the two connecting members will inevitably change. In this design, the second connecting member 3 can rotate relative to the ball head assembly 1, thus solving this problem.

[0038] The parts not elaborated in the above content are prior arts and will not be elaborated.
