Description

Technical Field

[0001] This utility model is a quick-install and quick-remove automotive rubber bushing, belonging to the technical field of automotive rubber bushings. Background Technology

[0002] Automotive rubber bushings are components used to connect the subframe to the vehicle body. Their primary function is to reduce vibration and improve NVH (noise, vibration, and harshness) performance. Rubber bushings or rubber bearings are widely used as damping elements in automotive chassis, mainly concentrated at the connections between the engine, transmission, driveshaft and the frame or body, as well as in the suspension system. Their main function is to attenuate vibrations transmitted from the engine, transmission system, and road surface to the vehicle body, thereby improving the vehicle's NVH performance.

[0003] Because automotive rubber bushings age over time, they need to be replaced regularly to ensure vehicle safety and comfort. Currently, replacing rubber bushings in automotive suspension systems usually involves prying them out, except when using specialized tools. While this replaces the bushings, it causes some damage to the suspension connections and is not quick. Therefore, there is an urgent need for a quick-install and quick-remove automotive rubber bushing to solve these problems. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a vehicle rubber bushing that can be quickly installed and disassembled, so as to solve the problems mentioned in the background art. This utility model has a reasonable structure and simple operation, which can quickly install and disassemble vehicle rubber bushings and reduce some damage to the vehicle frame.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a vehicle rubber bushing that can be quickly installed and disassembled, comprising a rubber bushing body, an outer sleeve, a rubber sleeve, an inner sleeve, an inner groove of the outer sleeve, an inner layer of the rubber sleeve, an outer groove of the rubber sleeve, an external threaded ring, an internal threaded ring, an inner support component, a threaded rod, an outer cover, and a threaded groove. The rubber bushing body can be divided into three parts: an outer sleeve, a rubber sleeve, and an inner sleeve, wherein the outer sleeve, the rubber sleeve, and the inner sleeve are sequentially fitted together. Multiple inner grooves are formed inside the outer sleeve, and multiple rubber grooves are formed on the outer surface of the rubber sleeve. The outer sleeve has an outer groove, and the inner sleeve is inserted into the inner layer of the rubber sleeve. The inner sleeve has an internal threaded ring and several external threaded rings on its outer surface. The inner support component is installed between the inner groove of the outer sleeve and the outer groove of the rubber sleeve. The front end of the threaded rod is provided with an outer cover, and the inner wall of the outer cover is provided with a threaded groove. The inner support component includes a support plate, a pocket plate, and a through hole. The support plate is installed between the inner groove of the outer sleeve and the outer groove of the rubber sleeve, and multiple support plate tail ends are connected with pocket plates. The pocket plate has a through hole in the middle position.

[0006] Furthermore, the size of the through hole in the middle of the pocket plate is adapted to the inner diameter of the internal thread ring inside the inner sleeve.

[0007] Furthermore, the internal threaded ring and the threaded rod inside the inner sleeve are a matching set of threaded structures.

[0008] Furthermore, the external threaded ring on the outer surface of the inner sleeve is adapted to the threaded groove on the inner wall of the outer cover.

[0009] Furthermore, the thickness of the support piece satisfies the combined thickness of the inner groove of the outer sleeve and the outer groove of the rubber sleeve.

[0010] Furthermore, both the outer and inner sleeves are made of sturdy materials, and the rubber sleeve is made of rubber.

[0011] The beneficial effects of this utility model are as follows: This utility model provides a quick-installation and disassembly automotive rubber bushing. Because this utility model adds an inner groove for the outer sleeve, an outer groove for the rubber sleeve, an external threaded ring, an internal threaded ring, a support plate, a pocket plate, a threaded rod, and an outer cover, the support plate installed between the outer sleeve and the rubber sleeve facilitates the installation and disassembly of the outer sleeve and the rubber sleeve. The support plate can also enhance the internal friction between the outer sleeve and the rubber sleeve, ensuring the tightness of the connection. The external threaded ring on the outer surface of the inner sleeve is installed through the threaded groove on the outer cover, which helps to achieve quick disassembly and installation of the rubber bushing body using the threaded rod.

Detailed Implementation

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] Please see Figures 1-4 This utility model provides a technical solution: a quick-installing and disassembly automotive rubber bushing, comprising a rubber bushing body 1, an outer sleeve 11, a rubber sleeve 12, an inner sleeve 13, an inner groove 2 of the outer sleeve, an inner layer of the rubber sleeve 3, an outer groove 4 of the rubber sleeve, an external threaded ring 5, an internal threaded ring 6, an inner support component 7, a threaded rod 8, an outer cover 9, and a threaded groove 10. The rubber bushing body 1 can be divided into three parts: the outer sleeve 11, the rubber sleeve 12, and the inner sleeve 13. The outer sleeve 11, the rubber sleeve 12, and the inner sleeve 13 are sequentially fitted together. The outer sleeve 11 has multiple inner grooves 2, the outer surface of the rubber sleeve 12 has multiple outer grooves 4, and the inner sleeve 13... The inner sleeve 13 is inserted into the inner layer 3 of the rubber sleeve 12. The inner sleeve 13 has an internal thread ring 6 and several external thread rings 5 ​​on its outer surface. The inner support component 7 is installed between the inner groove 2 of the outer sleeve 11 and the outer groove 4 of the rubber sleeve 12. The front end of the threaded rod 8 is provided with an outer cover 9, and the inner wall of the outer cover 9 is provided with a threaded groove 10. The inner support component 7 includes a support piece 71, a pocket plate 72 and a through hole 73. The support piece 71 is installed between the inner groove 2 of the outer sleeve 11 and the outer groove 4 of the rubber sleeve 12. The tail ends of multiple support pieces 71 are also connected by pocket plates 72. The pocket plate 72 has a through hole 73 in the middle position.

[0020] As the first embodiment of this utility model: both the outer sleeve 11 and the inner sleeve 13 are made of sturdy materials, and the rubber sleeve 12 is made of rubber. The size and thickness of the support piece 71 meet the combined thickness of the inner groove 2 of the outer sleeve and the outer groove 4 of the rubber sleeve. This design, by installing the support piece 71 between the outer sleeve 11 and the rubber sleeve 12, facilitates the assembly and disassembly of the outer sleeve 11 and the rubber sleeve 12. Furthermore, the support piece 71 can enhance the internal friction between the outer sleeve 11 and the rubber sleeve 12, ensuring the tightness of the connection. The external threaded ring 5 on the outer surface of the inner sleeve 13 is adapted to the threaded groove 10 on the inner wall of the outer cover 9, and the internal threaded ring 6 inside the inner sleeve 13 is adapted to the threaded groove 10. The rod 8 is a set of matching threaded structures. This design connects the threaded rod 8 with the inner threaded ring 6 and is installed with the outer threaded ring 5 on the outer surface of the inner sleeve 13 through the threaded groove 10 on the outer cover 9. This facilitates the disassembly and installation of the rubber bushing body 1 by pulling the threaded rod 8. The size of the through hole 73 in the middle of the pocket plate 72 is adapted to the inner diameter of the inner threaded ring 6 inside the inner sleeve 13. This design connects the threaded rod 8 with the pocket plate 72 and the support plate 71 by passing the threaded rod 8 through the through hole 73 in the middle of the pocket plate 72. This facilitates the pulling of the outer sleeve 11, rubber sleeve 12 and inner sleeve 13 inside the rubber bushing body 1.

[0021] As a second embodiment of this utility model: When replacing the rubber bushing of a car, firstly, the threaded rod 8 in the tool is screwed into the inner thread ring 6 of the inner sleeve 13 by rotation. Then, when the outer cover 9 on the threaded rod 8 reaches the top of the inner sleeve 13, the threaded groove 10 in the outer cover 9 is also screwed into the outer thread ring 5 on the surface of the inner sleeve 13. In this way, when the personnel disassemble the rubber bushing body 1, the entire rubber bushing body 1 will be pulled and removed from the car suspension connection. Since there is a support plate 71 with a pocket plate 72 between the outer sleeve 11 and the rubber sleeve 12, the support plate 71 needs to be removed first in order to separate the outer sleeve 11 and the rubber sleeve 12. Similarly, when installing the rubber bushing body 1, the threaded rod 8 is connected to each part of the rubber bushing body 1 beforehand. Then, the threaded rod 8 is passed through the car suspension connection, and the rubber bushing body 1 is pulled into the car suspension connection from the back to complete the replacement and installation of the rubber bushing.
