Description

Technical Field

[0001] The utility model relates to the field of automobile cables, in particular to a low-noise automobile cable. Background Art

[0002] Automotive cables, also known as automotive cables or automotive control cables, are mechanical devices used in vehicle control systems. They play the role of transmitting force and motion in automobiles, and are usually used to control components such as throttles, clutches, brakes, and transmissions. Automotive cables can be divided into many types, including throttle cables, clutch cables, brake cables, and transmission cables. Automotive cables are usually composed of an inner wire (steel wire or wire rope) and an outer shell (plastic or metal tube). The inner wire is responsible for transmitting tension or thrust, while the outer shell protects the inner wire and provides support. High-quality automotive cables need to have characteristics such as high strength, wear resistance, corrosion resistance, and low friction to ensure their reliability and stability in long-term use.

[0003] The handbrake cable is a type of brake cable, which is composed of an internal steel wire and an external casing. There are special buckles at both ends of the handbrake cable, one end is connected to the handbrake cable zipper busbar, and the other end is connected to the brake cylinder. After long-term use, the friction between the steel wire and the casing will produce noise. At the same time, dust and sand often enter the connection between the steel wire and the casing. When the cable is in use, the steel wire mixed with sand and dust comes into contact with the casing, which makes a louder noise. The noise is transmitted to the interior of the car, reducing driving comfort and affecting the service life of the cable due to wear. Summary of the invention

[0004] 1. Technical issues to be solved

[0005] The technical problem to be solved by the utility model is that after the handbrake cable is used for a long time, the friction between the steel wire and the sleeve will generate noise. At the same time, dust and sand often enter the connection between the steel wire and the sleeve. When the cable is in use, the steel wire mixed with sand and dust contacts the sleeve, which makes a greater noise. The noise is transmitted to the interior of the car, resulting in reduced driving comfort and affecting the service life of the cable due to wear.

[0006] (II) Technical solution

[0007] In order to solve the above problems, the utility model provides the following technical solutions:

[0008] A low-noise automobile cable comprises a cable body, a sleeve is arranged on the outer side of the cable body, one end of the cable body is a busbar joint, and the other end is a working joint, a connecting seat is arranged on the busbar joint, an extension tube is arranged near one end of the sleeve between the busbar joint and the working joint, a dustproof tube is arranged on the extension tube, the other end of the dustproof tube is fixedly connected to the sleeve, a lubrication channel is arranged inside the sleeve, an oil filling port is opened on the outer side of the sleeve, and sealing heads are arranged at both ends of the sleeve.

[0009] Furthermore, the extension tube is fixedly connected to the cable body, and the extension tube is made of metal.

[0010] Furthermore, the dustproof tube is a corrugated tube, one end of which is fixedly bonded to the extension tube, and the other end of which is fixedly bonded to the sleeve.

[0011] Furthermore, the oil filling port is in the shape of an air nozzle, a thread is arranged on the outer side of the oil filling port, and a sealing cover is arranged on the oil filling port.

[0012] Furthermore, the sealing head is in a cover shape, a through hole is provided at the center, and a rubber ring is provided on the sealing head.

[0013] (III) Beneficial effects

[0014] The beneficial effects of the utility model are:

[0015] By expanding the diameter of the casing, a lubrication channel is created inside to inject lubricating grease, thereby reducing the friction between the cable wire and the casing, slowing down aging fatigue, and reducing the noise generated by friction. The sealing head is used to slow down the loss of lubricating grease, and dust-proof pipes are set at the connection between the two ends of the cable body and the casing to prevent the entry of external dust and gravel.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-3 A low-noise automobile cable is shown, comprising a cable body 1, a sleeve 2 is provided on the outer side of the cable body 1, one end of the cable body 1 is a busbar joint 1a, and the other end is a working joint 1b, a connecting seat 3 is provided on the busbar joint 1a, an extension tube 4 is provided near one end of the busbar joint 1a and the working joint 1b near the sleeve 2, a dustproof tube 5 is provided on the extension tube 4, the other end of the dustproof tube 5 is fixedly connected to the sleeve 2, a lubrication channel is provided inside the sleeve 2, an oil filling port 6 is opened on the outer side of the sleeve 2, and sealing heads 2a are provided at both ends of the sleeve 2.

[0023] The extension tube 4 is fixedly connected to the cable body 1. The extension tube 4 is made of metal. The extension tubes at both ends of the cable body 1 are respectively welded to the busbar joint 1a and the working joint 1b, so that the extension tube 4 is always close to the busbar joint 1a and the working joint 1b, and thereby carries the dustproof tube 5. The dustproof tube 5 is connected to the extension tube 4 and the sleeve 2 by an adhesive. When the busbar joint 1a is pulled by the handbrake, the dustproof tube 5 can be stretched to follow the change, always covering the connecting seat 3 and the connection between the cable body 1 and the sleeve 2 to prevent external dust and gravel from entering for protection.

[0024] The dustproof tube 5 is a corrugated tube, which is connected by a plastic corrugated tube and can be extended and contracted as the cable body 1 is stretched.

[0025] The oil filling port 6 is in the shape of an air nozzle, and a thread is arranged on the outer side of the oil filling port 6. A sealing cover 6a is arranged on the oil filling port 6. The oil filling port 6 is used to inject lubricating oil from the outside. The lubricating oil can be added through the oil filling port 6 or quantitatively injected through a syringe. Then the lubricating oil enters the lubrication channel inside the sleeve 2 and contacts the cable body 1. When the cable is used, the friction between the cable wire and the sleeve 2 is lubricated to reduce noise and wear.

[0026] The sealing head 2a is in a cover shape with a through hole in the center. A rubber ring 7 is provided on the sealing head 2a. The sealing head is in a cover shape to reduce the loss of lubricating oil and block it. During long-term operation and pulling, the lubricating oil will be brought out as the cable body 1 is pulled and drawn, and enter the dustproof tube 5 outside. The sealing head 2a and the rubber ring 7 can reduce the loss, and the dustproof tube 5 can be replaced regularly to keep the inside clean.
