Description

Technical Field

[0001] The utility model relates to the technical field of shift cables, in particular to a shift cable for an automobile without friction. Background Technique

[0002] The shift cable is connected to the shift mechanism at one end and to the transmission at the other end. Before the shift cable breaks or loses rigidity, the general precursor is that the gear is not easy to engage, or it cannot be engaged in one go. For manual cars, there are generally two shift cables, and for automatic cars, there is generally one shift cable.

[0003] The existing technology has the following problems:

[0004] 1. Most of the existing shift cables are composed of multiple groups of metal wire cores. This also causes the shift cable to transmit high-frequency gear knocking sounds generated during gear selection / shift of the transmission to the vehicle interior through internal friction vibration during use, which makes the driver feel irritated and affects driving safety. Indirectly, the practicability of the shift cable is reduced, and it is not convenient to promote.

[0005] 2. The existing shift cables have not particularly ideal weather resistance, which also leads to problems such as damage or impairment when the shift cables work in harsh environments for a long time, and they cannot meet the usage requirements. Content of the Utility Model

[0006] In view of the deficiencies of the existing technology, the utility model provides a shift cable for an automobile without friction, which solves the problems that in the existing shift cables during use, high-frequency gear knocking sounds generated during gear selection / shift of the transmission are transmitted to the vehicle interior through internal friction vibration of the shift cable, making the driver feel irritated and affecting driving safety, and the weather resistance of the shift cable itself is not particularly ideal, resulting in damage or impairment when the shift cable works in harsh environments for a long time.

[0007] To achieve the above object, the utility model provides the following technical solution: A shift cable for an automobile without friction, including a metal wire core, a elastic layer is arranged on the outer surface of the metal wire core, a filling layer is arranged on the outer surface of the elastic layer, a buffer layer is arranged on the outer surface of the filling layer, a cold-resistant layer is arranged on the outer surface of the buffer layer, a tensile-resistant layer is arranged on the outer surface of the cold-resistant layer, a heat-resistant layer is arranged on the outer surface of the tensile-resistant layer, a corrosion-resistant layer is arranged on the outer surface of the heat-resistant layer, and a wear-resistant layer is arranged on the outer surface of the corrosion-resistant layer.

[0008] As a preferred technical solution of the utility model, the inner wall of the elastic layer is attached to the outer surface of the metal wire core.

[0009] As a preferred technical solution of the utility model, the inner wall of the buffer layer is attached to the outer surface of the filling layer.

[0010] As a preferred technical solution of the present utility model, the inner wall of the cold-resistant layer is attached to the outer surface of the buffer layer.

[0011] As a preferred technical solution of the present utility model, the inner wall of the tensile-resistant layer is attached to the outer surface of the cold-resistant layer.

[0012] As a preferred technical solution of the present utility model, the inner wall of the heat-resistant layer is attached to the outer surface of the tensile-resistant layer.

[0013] As a preferred technical solution of the present utility model, the inner wall of the corrosion-resistant layer is attached to the outer surface of the heat-resistant layer.

[0014] Compared with the prior art, the present utility model provides a shift wire for an automobile without friction, having the following beneficial effects:

[0015] 1. For the shift wire for an automobile without friction, by providing a metal wire inner core, an elastic layer, a filling layer and a buffer layer, when facing high-frequency gear clash sounds, first, the buffer layer provided weakens the vibration transmitted to the shift wire by the gear clash sound, and then, through the elastic layer provided, while the shift wire weakens the vibration, it can also isolate the metal collision and friction between the metal wire inner cores, making the vibration weaken more significantly, thereby reducing the gear clash sound transmitted into the vehicle. This design avoids the problem that during the use of the shift wire, when the transmission generates high-frequency gear clash sounds during gear selection / shift, the friction vibration inside the shift wire is transmitted into the vehicle, making the driver feel irritated and affecting driving safety, and indirectly improves the practicability of the shift wire, facilitating its popularization.

[0016] 2. For the shift wire for an automobile without friction, by providing a cold-resistant layer, a tensile-resistant layer, a heat-resistant layer, a corrosion-resistant layer and a wear-resistant layer, when working in a harsh environment, through the wear-resistant layer provided, the wear resistance of the shift wire is increased, and the wear during the use of the shift wire is reduced; through the corrosion-resistant layer provided, the service life of the shift wire is increased, and the shift wire is prevented from being eroded by the external harsh environment; through the tensile-resistant layer provided, a certain elastic deformation ability is provided for the shift wire, facilitating the use of the shift wire; through the mutual cooperation of the cold-resistant layer and the heat-resistant layer, the shift wire has good cold resistance and heat resistance, avoiding the influence of high and low temperatures on the service life of the shift wire, so that the shift wire has good weather resistance and can adapt to various environments.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative work belong to the scope of protection of the present invention.

[0020] Please refer to Figure 1 , in this implementation plan: An anti-friction shift cable for an automobile includes a metal wire inner core 1.

It is convenient to increase the wear resistance of the shift cable and reduce the wear of the shift cable during use by setting the wear-resistant layer 9.

[0021] In this embodiment, the inner wall of the elastic layer 2 is attached to the outer surface of the metal wire inner core 1, which is convenient for weakening the vibration of the shift cable and isolating the metal collision and friction between the metal wire inner cores 1 through the set elastic layer 2, making the vibration more significantly weakened, thereby reducing the gear clash sound transmitted into the vehicle; the inner wall of the buffer layer 4 is attached to the outer surface of the filling layer 3, which is convenient for weakening the vibration transmitted by the gear clash sound to the shift cable through the set buffer layer 4; the inner wall of the cold-resistant layer 5 is attached to the outer surface of the buffer layer 4, which is convenient for the shift cable to have good cold resistance through the cold-resistant layer 5, avoiding the influence of low temperature on the service life of the shift cable, so that the shift cable has good weather resistance and can adapt to various environments; the inner wall of the tensile-resistant layer 6 is attached to the outer surface of the cold-resistant layer 5, which is convenient for providing a certain elastic deformation ability for the shift cable through the set tensile-resistant layer 6, facilitating the use of the shift cable; the inner wall of the heat-resistant layer 7 is attached to the outer surface of the tensile-resistant layer 6, which is convenient for the shift cable to have good heat resistance through the heat-resistant layer 7, avoiding the influence of high temperature on the service life of the shift cable, so that the shift cable has good weather resistance and can adapt to various environments; the inner wall of the corrosion-resistant layer 8 is attached to the outer surface of the heat-resistant layer 7, which is convenient for increasing the service life of the shift cable and avoiding the erosion of the shift cable by the external harsh environment through the set corrosion-resistant layer 8.

[0022] Working principle and usage process of the present utility model: When facing high-frequency gear clash sounds, first, the buffer layer 4 provided on the outer surface of the filling layer 3 weakens the vibration transmitted to the shift cable by the gear clash sound. Then, through the provided elastic layer 2, while the shift cable weakens the vibration, it can also isolate the metal collision and friction between the metal cores 1, making the vibration weaken more significantly, thereby reducing the gear clash sound transmitted into the vehicle. This design avoids the problem that during the use of the shift cable, when facing high-frequency gear clash sounds generated by the transmission during gear selection / shift, the friction vibration inside the shift cable is transmitted into the vehicle, making the driver feel irritated and affecting driving safety. When working in a harsh environment, through the provided wear-resistant layer 9, the wear resistance of the shift cable is increased, and the wear of the shift cable during use is reduced. Through the provided corrosion-resistant layer 8, the service life of the shift cable is increased, and the shift cable is prevented from being eroded by the external harsh environment. Through the provided tensile-resistant layer 6, a certain elastic deformation ability of the shift cable is provided, facilitating the use of the shift cable. Through the mutual cooperation of the cold-resistant layer 5 and the heat-resistant layer 7, the shift cable has good cold resistance and heat resistance, avoiding the influence of high and low temperatures on the service life of the shift cable, so that the shift cable has good weather resistance and can adapt to various environments. This design avoids the problem that the shift cable is prone to damage or being damaged when working in a harsh environment for a long time, meeting the usage requirements.
