[0023] The preferred embodiments of the utility model are specifically described below in combination with the drawings, wherein the drawings constitute a part of this application, and are used to explain the principles of the embodiments of the utility model, and are not used to limit the scope of the utility model.
[0024] The inlaying cable of reducing gear shift handball resonance jitters in the embodiment relates to the automobile transmission system technical field, and sets up the damping layer 310 between the sheath 330 and the core line 320 of inlaying cable body 300, and the damping layer 310 can hinder the transmission of vibration, and reduce the influence of gear shift handball vibration on the driver.
[0025] Referring to Figures 1 to 4 In this embodiment, the cable for reducing the resonance and shaking of the shift knob includes a vibration end 100, a control end 200, and a cable body 300. The vibration end 100 is connected to a gearbox of a vehicle and can control the shifting of the gearbox. The control end 200 is connected to a shift knob, and a driver can directly operate the shift knob to act on the control end 200. The two ends of the cable body 300 are connected to the control end 200 and the vibration end 100, respectively. The shifting action from the control end 200 can be transmitted to the vibration end 100 through the cable body 300 to control the shifting of the gearbox. The mechanical vibration from the vibration end 100 can be transmitted to the shift knob through the cable body 300.
[0026] The cable body 300 includes a damping layer 310, a core wire 320, and a sheath 330. The core wire 320 is mainly responsible for the transmission of force and displacement. The sheath 330 provides protection and maintains the stability of the cable. The damping layer 310 is specifically designed to absorb and weaken vibrations.
[0027] The damping layer 310 is filled between the core wire 320 and the sheath 330 and can absorb and consume the vibration energy transmitted from the gearbox, thereby effectively reducing the transmission of these vibrations to the control end 200 and the cockpit through the cable body 300.
[0028] When the cable body 300 is subjected to gearbox vibration, it will generally resonate to some extent (especially under high-frequency vibration). The damping layer 310 suppresses the occurrence of resonance by absorbing vibration, thereby effectively reducing the shaking sensation of the shift knob.
[0029] During use, when the vibration is transmitted to the control end 200 through the core wire 320, each segment of the transmission path will encounter resistance from the damping material due to the presence of the damping layer 310, causing the transmitted vibration to gradually diminish.
[0030] In some embodiments, referring to Figure 2 and Figure 3 The damping layer 310 is a lubricating grease damping layer 310. The lubricating grease itself has good viscosity and vibration absorption properties, which can effectively absorb the vibration energy transmitted from the gearbox and reduce the transmission of vibration. This property enables the lubricating grease to effectively absorb low-frequency and medium-frequency vibrations and prevent these vibrations from being transmitted to the control end through the cable.
[0031] The damping layer 310 also contains PTFE micro powder. PTFE (Polytetrafluoroethylene) is a material with extremely low friction coefficient and excellent chemical stability, which has strong wear resistance and vibration resistance. The micronized PTFE particles can be uniformly distributed in the lubricating grease, making the damping effect of the lubricating grease more balanced and stable.
[0032] PTFE micro-powder with extremely low friction coefficient can greatly reduce the internal friction of the cable after being added to the grease, and reduce the heat and wear caused by friction. Especially on the contact surface between the core wire 320 and the sheath 330 of the cable, the lubricating effect of the PTFE micro-powder helps to reduce wear and tear and prolong the service life of the cable system.
[0033] In some embodiments, referring to Figure 2 The cross-section of the damping layer 310 is annular,
[0034] The annular cross-section structure can uniformly distribute the damping effect, ensuring that the entire damping layer 310 maintains consistent performance during the operation of the cable. Compared with traditional flat or other irregularly shaped damping layers 310, the annular design makes the damping layer 310 more uniform when subjected to vibrations transmitted by the gearbox, thereby reducing the situation of local over-damping or vibration transition and improving the overall vibration suppression effect.
[0035] The annular cross-section structure enables the damping layer 310 to surround the core wire 320 of the cable, forming a more efficient vibration isolation system. Due to the integrity of the annular structure, the damping layer 310 enhances its effect on the vibration transmission path, and it can absorb vibrations within a 360° range, hindering the propagation of vibrations to the outside, thereby effectively reducing the transmission of vibrations and noise.
[0036] At the same time, the annular structure can increase the contact area between the damping layer 310 and the core wire 320 and the sheath 330 to a greater extent, so that vibration energy can be absorbed in a larger range. This not only improves the damping effect, but also further optimizes the ability to suppress high-frequency vibrations.
[0037] In the specific implementation process, the damping layer 310 is arranged relatively close to the operating end 200 on the cable body 300. The operating end connected to the cable body 300 is the most direct receiving position of vibration, and the damping layer 310 is arranged at this position to specifically process the vibration transmitted to the operating end 200. By placing the damping layer 310 close to the operating end 200, the vibration that may cause discomfort to the driver in the gearbox can be effectively absorbed more accurately, without having to be processed through the entire cable body 300, avoiding unnecessary energy waste or overdesign.
[0038] The arrangement of the damping layer 310 close to the operating end 200 can quickly absorb and consume the vibration energy transmitted by the gearbox into the cable, so that the vibration amplitude of the operating end 200 is significantly weakened before reaching the driver's hand, reducing the "resonance effect" of vibration transmission.
[0039] In some embodiments, the core wire 320 comprises a plurality of twisted steel wires, which have strong mechanical properties and durability, and the design of the twisted structure increases the strength and rigidity of the cable core wire 320.
[0040] The damping layer 310 is partially filled between the plurality of twisted steel wires, and the damping layer 310 can be in direct contact with each steel wire to form a more compact contact surface. This structure can ensure that the damping layer 310 effectively plays a role in the vibration transmission process and absorbs and attenuates vibration energy,
[0041] Since the damping layer 310 is filled between the steel wires, the cable body 300 can be uniformly distributed between the steel wires when subjected to vibration, avoiding displacement or compression of the damping layer 310 when subjected to external force.
[0042] In some embodiments, referring to Figure 2 and Figure 3 , the sheath 330 comprises a cladding layer 331, a reinforcing layer 332, and an inner lining layer 333 nested from the outside to the inside. By arranging the cladding layer 331, the reinforcing layer 332, and the inner lining layer 333, the overall structure of the sheath 330 is enhanced, and each layer of material can play its specific function, improving the strength and impact resistance of the cable.
[0043] The cladding layer 331 can provide protection to avoid direct erosion of the inner layer material by external factors such as friction, environmental influences, etc.
[0044] The reinforcing layer 332 improves the mechanical strength of the sheath 330, enhances the ability to resist tension and shear force, and prevents the sheath 330 from being damaged due to excessive stress or external impact during use.
[0045] The inner lining layer 333 provides higher wear resistance to ensure the normal operation of the cable core wire 320 and avoid the influence of the external environment on the damping layer 310.
[0046] The inner lining layer 333 is in direct contact with the damping layer 310, which helps to ensure that the damping layer 310 plays the best damping role during the operation of the cable. The material of the inner lining layer 333 is usually tough, which can protect the damping layer 310 from being compressed or displaced by external force, and the friction of the inner lining layer 333 can further enhance the vibration absorption effect of the damping layer 310.
[0047] As a further embodiment, the reinforcing layer 332 is embedded with steel wires, and a plurality of steel wires are arranged equidistantly around the core wire 320. The steel wires have high tensile strength, which can effectively enhance the overall strength and rigidity of the cable. By embedding the steel wires in the reinforcing layer 332 and arranging a plurality of steel wires equidistantly around the core wire 320, the tensile force borne by the cable can be evenly distributed, the deformation of the cable during operation can be reduced, and the tensile performance of the cable can be improved.
[0048] The uniform distribution of the plurality of steel wires can effectively prevent the cable from excessive bending or twisting due to excessive external tension during operation, and maintain the stability and shape of the cable.
[0049] The inner lining layer 333 is a wear-resistant layer, which can effectively prevent the inner lining layer 333 from being damaged due to friction or wear during long-term use. Since the cable rubs against the core wire 320, the damping layer 310 and other internal components during operation, especially during high-speed or frequent gear shifting, the design of the wear-resistant layer can significantly reduce the wear caused by friction, thereby prolonging the service life of the entire cable.
[0050] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any skilled person in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered by the present application.
