Description

Technical Field

[0001] This utility model relates to the field of truck throttle cable technology, specifically a novel throttle cable structure for trucks. Background Technology

[0002] A truck throttle cable is a mechanical structure used to transmit throttle pedal signals to the truck engine. Existing truck throttle cables have an armored inner liner on the outer sheath to improve the overall structural strength of the outer sheath and protect the internal throttle cable body. In the installation structure of the throttle cable, the control and actuator connectors at both ends of the throttle cable body are not perfectly symmetrical with their corresponding mounting points. For example, an L-shaped connector is fixed on only one side. Due to uneven stress on the mounting points, shear forces can occur between the control and actuator connectors and the throttle cable body, causing damage and breakage at the throttle cable connection points.

[0003] Throttle cable breakage is a common occurrence during driving, and many drivers have encountered it. This is mainly because trucks typically travel for long periods, resulting in frequent use of the throttle cable, making it more prone to breakage. Although replacing a damaged throttle cable is quite simple, truck drivers usually don't carry a spare. If a throttle cable breaks while driving, it's often difficult to find a repair shop along the way, making the problem quite troublesome and causing inconvenience for the driver. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a novel throttle cable structure for trucks, which solves the problem that existing throttle cables lack emergency measures, leading to breakage of the throttle cable connection during driving and causing inconvenience to the driver.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A new type of throttle cable structure for trucks includes a steel strand, a control end connector and an execution end connector connected to both ends of the steel strand, and an outer sheath movably sleeved on the surface of the steel strand. Both ends of the outer sheath are fitted with external threaded sleeves movably sleeved on the surface of the steel strand, and the interior of the external threaded sleeves is provided with insertion holes for inserting the outer sheath.

[0007] The outer sheath includes an inner liner tube, a round steel pipe and a flat steel armored pipe fitted on the surface of the inner liner tube, and an outer sleeve fitted on the outside of the round steel pipe and the flat steel armored pipe, wherein the round steel pipe is located at both ends of the flat steel armored pipe.

[0008] Preferably, it also includes a plastic end cap that is installed on the end of the external threaded sleeve away from the outer sheath and is movably sleeved on the surface of the steel strand.

[0009] Preferably, it also includes a fixing nut and washer mounted on the surface of the external threaded sleeve for installing and fixing the outer sheath.

[0010] Preferably, the inner liner is a PE pipe and the outer liner is a PVC pipe.

[0011] Preferably, the length of the round steel pipe is the same as that of the insertion hole.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This invention features independent round steel pipes at both ends of the flat steel armored tube inside the outer sheath of the throttle cable. Since the entire length of the throttle cable between the control and actuation ends has a margin, when the connection at the end of the steel strand breaks, it is only necessary to remove the control or actuation end connector at the broken end, remove the external threaded sleeve and cut off a section of the outer sleeve corresponding to the insertion hole, remove the round steel pipe, and cut off the corresponding length of the inner liner. This shortens the overall length of the outer sheath to accommodate the shortened end length caused by the breakage of the steel strand. Reinstalling the external threaded sleeve and the control or actuation end connector at the broken end of the steel strand restores the throttle function, achieving a temporary emergency to ensure the truck can smoothly travel to the repair shop. The operation is simple and convenient, solving the problem of existing throttle cables lacking emergency measures, leading to breakage at the throttle cable connection point during driving and causing inconvenience to the driver.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figure 1-4 As shown, this utility model provides a technical solution: a novel throttle cable structure for trucks, including a steel strand 1, a control end connector 2 and an execution end connector 3 connected to both ends of the steel strand 1, and an outer sheath 4 movably sleeved on the surface of the steel strand 1. Both ends of the outer sheath 4 are fitted with external threaded sleeves 5 movably sleeved on the surface of the steel strand 1. It also includes a plastic end cap 6 installed at the end of the external threaded sleeve 5 facing away from the outer sheath 4 and movably sleeved on the surface of the steel strand 1. It also includes a fixing nut 7 and a washer 8 installed on the surface of the external threaded sleeve 5 for installing and fixing the outer sheath 4.

[0021] The internal part of the external threaded sleeve 5 is provided with a socket 501 for inserting the outer sheath 4. The outer sheath 4 includes an inner liner 401, a round steel pipe 402 and a flat steel armored pipe 403 sleeved on the surface of the inner liner 401, and an outer sleeve 404 sleeved on the outside of the round steel pipe 402 and the flat steel armored pipe 403. The round steel pipe 402 is located at both ends of the flat steel armored pipe 403. The inner liner 401 is a PE pipe, and the outer sleeve 404 is a PVC pipe. The length of the round steel pipe 402 is the same as that of the socket 501.

[0022] Working principle:

[0023] When the connection at the end of the steel strand 1 breaks, remove the control end connector 2 or the actuator end connector 3 at the broken part, remove the external threaded sleeve 5, cut off a section of the outer sleeve 404 according to the length of the insertion hole 501, remove the round steel pipe 402, and then cut off the corresponding length of the inner liner 401. This will shorten the length of the entire outer sheath 4 to accommodate the shortened end length caused by the breakage at the end of the steel strand 1. Then, the external threaded sleeve 5 and the control end connector 2 or actuator end connector 3 at the broken end of the steel strand 1 can be reinstalled to restore the throttle function and achieve the effect of temporarily ensuring that the truck can drive smoothly to the repair shop.
