Description

Technical Field

[0001] This utility model belongs to the field of mechanical automatic transmissions and relates to wiring harness clips, specifically a wiring harness clip for fixing integrated AMT wiring harnesses. Background Technology

[0002] In recent years, automatic transmission commercial vehicles have become increasingly popular with customers, and automated manual transmissions (AMTs) have become a key development direction for major OEMs. Compared to manual transmissions, AMTs require a wiring harness assembly to connect components such as the transmission control unit (TCU), clutch actuator, shift actuator, solenoid valves, and sensors. The wiring harness assembly provides electricity and transmits signals to the electrical components, thereby enabling automatic clutch engagement and disengagement and automatic gear shifting. Because the entire housing is more centralized and concise, the wiring harness assembly significantly reduces the number of wiring branches and connectors, improving simplicity and reliability.

[0003] Integrated AMT wiring harnesses reduce most branch lines and connectors, but a few sensors, due to their installation location, cannot be integrated into the gearbox cover and still require connection via the wiring harness. The connection between the wiring harness and the sensor still uses a connector-to-connect method, specifically, the female connector of the wiring harness connects to the male connector of the sensor mounted on the gearbox. Because commercial vehicles often operate in harsh environments with bumpy road conditions, it has been found in the aftermarket that integrated wiring harness connectors are prone to loosening and poor contact under prolonged vibration, leading to occasional open circuit faults and sensor signal loss, affecting the operation of the gearbox and the entire vehicle.

[0004] The integrated AMT replaces the PCA (Position Control Actuator) of the previous modular AMT with a CCA (Clutch Control Actuator) to actuate the clutch. The CCA has two wiring harness connectors: one for the input shaft speed sensor and the other for the CCA displacement sensor. Frequent movement of this wiring harness can cause the connectors to loosen, leading to sensor signal loss and causing the AMT to malfunction. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a wire harness clip for fixing integrated AMT wire harnesses, so as to solve the technical problem that integrated wire harness connectors are prone to loosening and poor contact under long-term vibration conditions.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A wire harness clip for fixing an integrated AMT wire harness includes a fixing plate, one end of which is provided with an arc-shaped wire harness fixing cylinder, and one side of the arc-shaped wire harness fixing cylinder is open and provided with a connecting plate at an acute angle to the fixing plate.

[0008] The top of the arc-shaped wire harness fixing cylinder and the connecting plate are provided with a rectangular hole, and an elastic sheet is provided in the rectangular hole.

[0009] This utility model specifically includes the following steps:

[0010] Bolt holes are provided on the fixing plate.

[0011] It also includes a limiting structure, which includes a limiting baffle disposed on one side of the fixed plate or a limiting hole disposed on the fixed plate.

[0012] The inner wall of the arc-shaped wire harness fixing cylinder is coated with a Dacromet coating.

[0013] The two ends of the arc-shaped wire harness fixing cylinder are provided with gradually expanding protrusions.

[0014] Compared with the prior art, the beneficial technical effects of this utility model are:

[0015] In this invention, an arc-shaped wire harness fixing cylinder is set on the fixing plate, so that the wire harness is fixed in the arc-shaped wire harness fixing cylinder, which reduces the shaking of the wire harness caused by vehicle bumps. By setting an elastic sheet, the wire harness can be easily put into the arc-shaped wire harness fixing cylinder and the wire harness can be tightened again, avoiding poor contact or detachment of the sensor. This solves the technical problem that integrated wire harness connectors in the prior art are prone to loosening and poor contact under long-term vibration conditions. Attached Figure Description

[0020] The specific content of this utility model will be further explained in detail below with reference to the embodiments. Detailed Implementation

[0021] It should be noted that, unless otherwise specified, all components in this utility model are components known in the art.

[0022] The following are specific embodiments of the present invention. It should be noted that the present invention is not limited to the following specific embodiments. All equivalent modifications made based on the technical solutions of this application fall within the protection scope of the present invention.

[0023] This utility model provides a wire harness clip for fixing an integrated AMT wire harness, including a fixing plate 1, an arc-shaped wire harness fixing cylinder 2 at one end of the fixing plate 1, and an opening on one side of the arc-shaped wire harness fixing cylinder 2 and a connecting plate 3 at an acute angle to the fixing plate 1.

[0024] The top of the arc-shaped wire harness fixing cylinder 2 and the connecting plate 3 are both provided with a rectangular hole 4, and an elastic piece 5 is provided in the rectangular hole 4.

[0025] In the above technical solution, the wiring harness clip is fixed on the reserved plane of the AMT housing. The wiring harness of the integrated AMT connecting the input shaft speed sensor and the CCA displacement sensor passes through the wiring harness clip. The wiring harness is restricted by the clip, which reduces the shaking of the wiring harness caused by vehicle bumps.

[0026] By setting an arc-shaped wire harness fixing cylinder 2 on the fixing plate 1, the wire harness is fixed in the arc-shaped wire harness fixing cylinder 2, reducing the shaking of the wire harness caused by vehicle bumps. By setting an elastic piece 5, the wire harness can easily enter the arc-shaped wire harness fixing cylinder 2 and be tightened again, avoiding poor contact or detachment of the sensor. This solves the technical problem that integrated wire harness connectors in the prior art are prone to loosening and poor contact under long-term vibration conditions.

[0027] Bolt holes 6 are provided on the fixing plate 1.

[0028] In the above technical solution, the fixing plate 1 is fixed to the surface of the AMT housing by the cooperation of the bolt hole 6 and the bolt.

[0029] It also includes a limiting structure 7, which includes a limiting baffle 701 disposed on one side of the fixed plate 1 or a limiting hole 702 disposed on the fixed plate 1.

[0030] In the above technical solution, the limiting baffle 701 or the limiting hole 702 respectively cooperate with the AMT, so that the fixing plate 1 is in close contact with the surface of the AMT housing, preventing the fixing plate 1 from rotating. Both different fixing methods can ensure that the wire harness clip itself does not move.

[0031] The inner wall of the arc-shaped wire harness fixing cylinder 2 is coated with Dacromet coating.

[0032] In the above technical solution, the Dacromet layer can prevent rust and corrosion, extending the service life of the wire harness clip.

[0033] Both ends of the arc-shaped wire harness fixing cylinder 2 are provided with gradually expanding protrusions 8.

[0034] In the above technical solution, the gradually expanding protrusion 8 can effectively prevent the two ends of the arc-shaped wire harness fixing cylinder 2 from cutting the wire harness.
