Description

Technical Field

[0001] The utility model relates to an AMT wiring harness, in particular to an integrated AMT wiring harness fixing housing structure. Background Art

[0002] In recent years, integrated automatic transmissions (AMTs) for commercial vehicles have stood out among numerous commercial vehicle AMT products due to their higher integration levels and lower failure rates. Integrated AMTs feature an integrated automatic transmission control unit (TCU), shift selector actuator, solenoid valves, and most sensors, all integrated into a single unit. These components are installed as a subassembly of the integrated actuator on the transmission cover.

[0003] The female connectors on the AMT wiring harness and the vehicle harness connect to the two male connectors on the integrated actuator, respectively. These connectors power, transmit signals, and control and actuate the electronic components on the AMT and vehicle, respectively. AMTs require strict control over sensor signals like speed and displacement. If a wiring harness failure prevents proper signal transmission, transmission performance and functionality can be affected. Therefore, ensuring the AMT wiring harness is securely mounted on the transmission and that the connectors are secure and reliable, without loosening, is crucial to ensuring the proper operation of the transmission and vehicle.

[0004] Chinese patent CN221316044U discloses an AMT harness fixing bracket and an AMT harness. By fixing the AMT harness plug in the through hole and supporting the entire vehicle harness through a support plate, the screw fixation at the AMT harness plug is eliminated. This solution can better fix the harness firmly on the gearbox and avoid the harness from swinging automatically, but it does not focus on further fixing the AMT harness plug end. In harsh working environments such as bumpy roads, the female connector of the AMT harness and the male interface of the integrated actuator are prone to loose connectors and poor contact under long-term vibration conditions, resulting in occasional open circuit failures and signal loss, affecting the operation of the gearbox and the entire vehicle.

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] Example 1: This embodiment provides an integrated AMT harness fixing housing structure, such as Figure 1 、 Figure 2 As shown, it includes an integrated actuator housing 1, a first male end interface 3, a second male end interface, a baffle 2, a first guide member 4 and a second guide member.

[0026] The first and second male connectors 3 are located on one side of the integrated actuator housing 1. The first male connector 3 is used for plugging and connecting with the female connector of the integrated AMT wiring harness, while the second male connector is used for plugging and connecting with the female connector of the vehicle wiring harness. A shielding plate 2 is provided on the side of the integrated actuator housing 1 where the first and second male connectors are located.

[0027] The baffle 2 includes an upper panel and two side panels. The upper panel is distributed along the length direction of the side surface of the integrated actuator housing 1, and is located at the upper end of the first male interface 3 and the second male interface. The width of the upper panel is greater than the width of the first male interface 3 and the second male interface extending outward. The two side panels are vertically connected to the two ends of the upper panel, respectively, and are distributed along the width direction of the side surface of the integrated actuator housing 1. The first male interface 3 and the second male interface are located between the two side panels. The baffle 2 is used to shield the plug-in connection between the first male interface 3 and the integrated AMT wiring harness female interface, as well as the plug-in connection between the vehicle wiring harness female interface and the second male interface. It can prevent external devices from colliding with the two plug-in connections, help to strengthen the stability of the plug-in connection, and reduce the possibility of the plug-in connection loosening due to factors such as vibration during use.

[0028] The first guide member 4 is arranged at one end of the shielding plate 2 and is close to the first male end interface 3. The first guide member 4 includes a first guide plate, a first wire harness guide groove 5 and a limit groove 6. In this embodiment, the first guide plate is an arc-shaped plate, and its axial direction is parallel to the side surface of the integrated actuator housing 1 where the first male end interface 3 is located. The first wire harness guide groove 5 is an arc-shaped groove located on the inner surface of the first guide plate, which is used to place the integrated AMT wire harness and guide the integrated AMT wire harness. The limit groove 6 is an arc-shaped groove located outside the first guide plate, and the extension direction of the limit groove 6 is arranged along the circumference of the first wire harness guide groove 5. The limit groove 6 is used to place the cable tie used to fix the integrated AMT wire harness, limit the cable tie, and prevent the cable tie from falling out.

[0029] The second guide member has the same structure as the first guide member 4 and is located at the other end of the shield 2, near the second male interface. The second guide member includes a second guide plate, a second wire harness guide slot, and a second retaining slot. The second guide plate is vertically connected to the other side panel of the shield 2. The second wire harness guide slot is used to accommodate and guide the entire vehicle wiring harness. The second retaining slot is used to accommodate the cable ties used to secure the entire vehicle wiring harness and to limit the position of the cable ties to prevent them from falling out.

[0030] Installation of the housing structure: Plug the female connector of the integrated AMT wiring harness into the first male connector 3 in the shielding plate 2, and plug the female connector of the vehicle wiring harness into the second male connector in the shielding plate 2. Arrange the integrated AMT wiring harness in the first harness guide groove 5, use a cable tie to tie the integrated AMT wiring harness in the first harness guide groove 5, and place the cable tie in the limit groove 6 to prevent it from slipping out along the first harness guide groove 5. Arrange the vehicle wiring harness in the second harness guide groove, use a cable tie to tie the entire vehicle wiring harness in the second harness guide groove, and place the cable tie in the second limit groove.

[0031] Example 2. This example differs from Example 1 in that the first guide plate is a square plate, parallel to the side of the integrated actuator housing 1 where the first male interface 3 is located. A first harness guide slot 5 is provided on one side of the first guide plate, along the installation direction of the integrated AMT harness. A retaining slot 6 is provided on the other side of the first guide plate, extending perpendicularly to the direction of the first harness guide slot 5. This retaining slot 6 is used to accommodate and positionally limit the cable tie used to secure the integrated AMT harness.
