Description

Technical Field

[0001] This application relates to the field of cable adjusters, and more particularly to a cable adjuster for racing cars. Background Technology

[0002] The main function of racing car cables is to precisely translate the driver's actions into mechanical movements using steel cables, ensuring that all systems of the race car operate normally according to the driver's intentions. These cables mainly include brake cables, throttle cables, clutch cables, and shift cables. Specifically, the brake cable pulls the brake components to achieve braking; the throttle cable controls the engine's throttle opening, adjusting the engine's power output; the clutch cable operates the clutch, enabling the disengagement and engagement of power during gear shifts; and the shift cable connects the shifter and gearbox to achieve gear shifting.

[0003] Even if racing cables are made of high-strength materials, they will still experience slight stretching and creep during long-term use or under stress, or thermal expansion and contraction due to temperature changes, resulting in slight changes in cable length and tension, which pose certain safety hazards. Therefore, we propose a racing cable adjuster. Utility Model Content

[0004] The purpose of this invention is to provide a cable adjuster for racing cars to solve the problems mentioned in the background art.

[0005] This application provides a racing car cable adjuster with the following technical solution: including:

[0006] A first flexible hose has a first cable slidably connected inside it, and a cover plate is provided on one side of the first cable. A base is provided below the cover plate, and a connecting device is provided on one side of the cover plate and the base. Opening the connecting device allows the cover plate and the base to be unfolded for assembly. Both the cover plate and the base have connecting grooves and adjusting cavities inside. One end of the first flexible hose is slidably connected to the connecting groove. A second flexible hose is provided on one side of the connecting groove, and a second cable is slidably connected inside the second flexible hose. One end of the second flexible hose is slidably connected to the connecting groove, and an adjusting slider is slidably connected to the inner wall of the adjusting cavity. A first connecting groove is provided on the surface of the adjusting slider. The first cable is slidably installed inside the first connecting groove, and the second cable is slidably installed inside the second connecting groove. First, the adjusting slider is placed inside the adjusting cavity. Then, one end of the first hose and one end of the second cable are slid into the connecting slots respectively. After that, the cover plate and the base are closed together, and the cover plate and the base are fixed by the connecting device to complete the installation. When the tension of the first cable changes, the second cable will drive the adjusting slider to slide towards the side of the second hose. Conversely, the adjusting slider will slide towards the side of the first hose, thereby adjusting the insufficient tension of the first cable or the second cable and reducing safety hazards.

[0007] Preferably, the connecting device includes a locking block and a buckle that are fixedly connected to the cover plate and the side wall of the base, and the locking block and the buckle are arranged alternately.

[0008] By adopting the above technical solution, firstly, one end of the second cable and one end of the first cable are slidably installed into the symmetrical second connecting groove and the first connecting groove, respectively. Then, the adjusting slider is placed inside the adjusting slide cavity of the cover plate or the base. At this time, one end of the first hose and one end of the second hose on one side of the adjusting slider can be slidably installed into the connecting slot. Then, the cover plate and the base are closed, and then the staggered clips and buckles are snapped together to complete the connection and fixation of the cover plate and the base. When it is necessary to disassemble the cover plate and the base, the clips and connecting holes can be separated to disassemble the cover plate and the base for maintenance and repair. The disassembly and installation method is simple and convenient.

[0009] Preferably, the bottom surface of the cover plate and the surface of the base are both fixedly connected with connecting rods, and the bottom surface of the cover plate and the surface of the base are both provided with connecting holes, with the connecting rods and connecting holes arranged alternately.

[0010] By adopting the above technical solution, when the cover plate and the base are closed, the connecting rod on the surface of the base will slide into the connecting holes that are staggered on the bottom surface of the cover plate, ensuring that the cover plate and the base are aligned after the closing work is completed, making it convenient to engage the locking block and the buckle, improving the ease of operation, and making it simple and convenient.

[0011] Preferably, the top end of the connecting rod is provided with an angle.

[0012] By adopting the above technical solution, the oblique angle provides a certain directional effect when the connecting rod slides into the symmetrical connecting hole, which facilitates the symmetrical connecting rod to slide into the connecting hole, improves the convenience of operation, and makes it easier to close the cover plate and the connecting rod.

[0013] Preferably, the top surface of the connecting hole is provided with an inclined surface.

[0014] By adopting the above technical solution, the inclined surface can provide a certain guiding effect when the connecting rod slides into the connecting hole, making it easier for the connecting rod to slide into the connecting hole, further improving the assembly convenience when installing the cover plate and the base, which is simple and effective.

[0015] Preferably, the bottom surface of the adjusting cavity is fixedly connected with multiple sliding rods.

[0016] By adopting the above technical solution, the contact between the slide rod and the adjusting slider is a line contact, while the contact between the bottom surface of the adjusting cavity and the surface of the adjusting slider is a surface contact. Line contact has less friction than surface contact. Surface contact has a large friction area and is more prone to local pressure concentration due to insufficient flatness, which increases resistance. In addition, dust and impurities can easily slide into the gaps of surface contact, which is not conducive to the movement of the adjusting slider.

[0017] Preferably, the adjusting slider, cover plate, and base are made of aluminum alloy.

[0018] By adopting the above technical solutions, aluminum alloy materials have higher strength and lighter weight, which is beneficial for their application in the field of motorsports.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] First, place the adjusting slider inside the adjusting cavity. Then, slide one end of the first hose and one end of the second cable into the connecting slots respectively. After that, close the cover plate and the base, and fix the cover plate and the base with the connecting device to complete the installation. When the tension of the first cable changes, the second cable will drive the adjusting slider to slide towards the second hose. Conversely, the adjusting slider will slide towards the first hose, thereby adjusting the insufficient tension of the first or second cable and reducing safety hazards. Attached Figure Description
