Description

Technical Field

[0001] This utility model relates to the field of limiting rubber sleeve technology, specifically a limiting rubber sleeve. Background Technology

[0002] Limiting rubber sleeves are commonly used in suspension systems, primarily to limit movement, protect equipment, reduce wear, and provide noise reduction. They also serve a certain limiting function, preventing large positional shifts in the suspension components placed on the rubber. Limiting rubber sleeves can effectively restrict the relative movement of components and prevent damage caused by excessive displacement.

[0003] Chinese invention patent, publication number CN101391567B, discloses a bidirectional limiting rubber bushing for a suspension system's triangular arm. It includes an inner bushing ring, a rubber ring, and an outer bushing ring. The rubber ring has an I-shaped axial cross-section, while the outer bushing ring has a T-shaped axial cross-section. A rubber deformation groove is provided between the bottom of the inner side of the I-shaped convex edge at one end of the rubber ring and the side end of the rubber ring. During installation, the I-shaped convex edge is pressed into the rubber deformation groove, making the outer edge of the convex edge flush with the side of the rubber ring, thus passing through the triangular arm hole. After reaching the installation position, the rubber's own elastic deformation restores its original shape, forming a boss on the rubber part, thereby achieving bidirectional limiting. Its ingenious design and simple structure truly achieve bidirectional limiting with a single part in the triangular arm hole, reducing the number of parts and simplifying installation steps, significantly lowering production and installation costs by 20% to 30%.

[0004] However, existing technologies still have significant shortcomings, such as:

[0005] The aforementioned device and the existing limiting rubber sleeve only achieve simple limiting of objects by the deformation of the rubber, and its limiting effect is poor. At the same time, although setting a cavity inside the rubber in the aforementioned device can increase the degree of deformation on both sides of the rubber to ensure the limiting effect, it affects the overall cushioning performance of the rubber sleeve.

[0025] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0026] Please refer to Figs. 1-3 The utility model provides a technical scheme:

[0027] A limiting rubber sleeve, including rubber sleeve main body 1, rubber sleeve main body 1 is symmetrically set with limiting groove 2 on the upper and lower sides, and rubber sleeve main body 1 is internally provided with deformation cavity 3, and rubber sleeve main body 1 is provided with auxiliary deformation cavity 4 on the two sides of limiting groove 2, and auxiliary deformation cavity 4 is communicated with deformation cavity 3.

[0028] In the embodiment, limiting groove 2 is arranged on the upper and lower sides of rubber sleeve main body 1, the upper limiting groove 2 is used to limit the object carried, the lower limiting groove 2 is used to ensure that rubber sleeve main body 1 can be better placed in a position, and also has the limiting effect on rubber sleeve main body 1, the setting of deformation cavity 3 enables rubber sleeve main body 1 to be greatly deformed inward when carrying the object, so that the two sides of rubber sleeve main body 1 can be raised to better limit the effect, when deformation cavity 3 is deformed, the gas in the cavity can be extruded into auxiliary deformation cavity 4, the deformation degree of the two sides of rubber sleeve main body 1 is ensured by the expansion of auxiliary deformation cavity 4, the lifting effect of the two sides is further ensured to ensure the limiting effect.

[0029] The deformation cavity 3 in the embodiment can be realized by the design of the mold, and the auxiliary deformation cavity 4 and the subsequent support rubber rod 5 and connecting rubber 6 can be realized by the design and improvement of the mold, which is a technology familiar to those skilled in the art and will not be described here.

[0030] The two sides of the limiting groove 2 are arc-shaped, the auxiliary deformation cavity 4 is arc-shaped and has the same curvature as the curvature of the two sides of the limiting groove 2, the auxiliary deformation cavity 4 is provided with four, and the sum of the internal volumes of the auxiliary deformation cavities 4 is not greater than the internal volume of the deformation cavity 3;

[0031] The auxiliary deformation cavity 4 is provided with four, which are respectively arranged on the two sides of the limiting groove 2, and the curvature of the auxiliary deformation cavity 4 is the same as the curvature of the limiting groove 2. Such arrangement ensures that the two sides of the limiting groove 2 can be better deformed and lifted when the auxiliary deformation cavity 4 is expanded;

[0032] The auxiliary support structure is arranged in the deformation cavity 3, which is used to ensure the elasticity of the rubber sleeve body 1 and disperse the force to the two sides to ensure the deformation degree of the two sides and further ensure the limiting of the load object. The auxiliary support structure includes a plurality of support rubber rods 5 arranged in the deformation cavity 3, and the support rubber rods 5 are symmetrically arranged in the deformation cavity 3. The number of the support rubber rods 5 is not less than three, and the support rubber rods 5 are inclined. The absolute value of the angle between the support rubber rod 5 and the upper wall of the deformation cavity 3 is 45 degrees.

[0033] In the embodiment, considering that the object needs to be better lifted on the two sides of the ballast rubber sleeve body 1 to achieve the limiting effect, the deformation cavity 3 is arranged in the rubber sleeve body 1. However, because of the arrangement of the deformation cavity 3, the buffering effect of the rubber sleeve body 1 is reduced. In the embodiment, the auxiliary support structure is arranged in the deformation cavity 3 to ensure the buffering effect of the rubber sleeve body 1.

[0034] The auxiliary support mechanism realizes auxiliary support through the support rubber rod 5. The inclined arrangement of the support rubber rod 5 ensures that the support rubber rod 5 can disperse the force to the two sides when the object is ballasted.

[0037] In this embodiment, in order to further ensure the inward concavity effect of the rubber sleeve body 1, a pressure groove 7 and an anti-slip point 8 are provided at the bottom of the limiting groove 2. This not only prevents the object pressed on the rubber sleeve body 1 from sliding, but also ensures that the opening of the triangular pressure groove 7, which is the base of the triangle, can shrink inward when it is pressed, thereby further ensuring the overall inward shrinkage and thus raising both sides to achieve a better limiting effect.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
