[0028] Example:
[0029] This embodiment provides an AMT wiring harness fixing bracket for a gear shifting actuator, such as... Figs. 1-2 As shown, it includes a central wire harness fixing bracket 1 and a pair of side wire harness fixing brackets 2. The central wire harness fixing bracket 1 includes a horizontal wire harness fixing plate 11 and a pair of vertical support plates 12. The top ends of the pair of vertical support plates 12 are fixedly connected to the two ends of the horizontal wire harness fixing plate 11, and a horizontal mounting plate 13 is provided at the bottom end of each pair of vertical support plates 12. The pair of side wire harness fixing brackets 2 are respectively installed on the longitudinal front edge of the pair of vertical support plates 12.
[0030] A first mounting through hole 14 is provided at both ends of the longitudinal rear edge of the horizontal wire harness fixing plate 11, and a middle wire harness fixing through hole 15 is provided at the middle of the longitudinal front edge of the horizontal wire harness fixing plate 11.
[0031] A second mounting through hole 16 is provided on each of the pair of horizontal mounting plates 13;
[0032] Each of the pair of side harness fixing brackets 2 has a side harness fixing through hole 23.
[0033] In this embodiment, the AMT harness fixing bracket is applied to the shift actuator 3. The central AMT harness connector 4 is mounted on the sensor 7 at the top of the shift actuator 3. The mounting surface of the central AMT harness connector 4 is the insertion surface between the central AMT harness connector 4 and the sensor 7. A side AMT harness connector 5 is mounted on each of the sensors 7 on both sides of the shift actuator 3. The mounting surface of the side AMT harness connector 5 is the insertion surface between the side AMT harness connector 5 and the sensor 7. The harness connectors of the central AMT harness connector 4 and the side AMT harness connectors 5 are used for inserting AMT harnesses. The central harness fixing bracket 1 passes through the first mounting through hole 14. The second mounting through hole 16 is fixedly installed on the shift actuator 3. It is fixed from both the top and bottom, which can better stabilize the fixed bracket and prevent the fixed bracket from deforming under external force. The AMT wire harness plugged into the middle AMT wire harness connector 4 is bundled and fixed by passing the wire harness clamp through the middle wire harness fixing through hole 15. The AMT wire harness plugged into the side AMT wire harness connector 5 is bundled and fixed by passing the wire harness clamp through the side wire harness fixing through hole 23. The fixing method is simple, quick and easy to operate, which can prevent the AMT wire harness from swinging, improve the installation stability of the AMT wire harness, avoid the situation that the AMT wire harness and the shift actuator 3 are not in good contact due to vehicle vibration, and ensure the normal operation of the vehicle.
[0034] As a preferred embodiment, the pair of side harness fixing brackets 2 are symmetrically oriented. Each side harness fixing bracket 2 includes an integrally formed vertical harness fixing plate 21 and a connecting plate 22. The vertical harness fixing plate 21 is parallel to the vertical support plate 12, and the connecting plate 22 is vertically fixed to the vertical support plate 12. The space between the connecting plate 22 and the vertical support plate 12 is a pre-set clearance space for the protruding end of the side AMT harness connector 5, providing sufficient operating space for AMT harness insertion. Furthermore, the vertical harness fixing plate 21 is brought closer to the AMT harness installed on the side AMT harness connector 5, thereby making the side harness fixing through hole 23 opened on the vertical harness fixing plate 21 closer to the AMT harness, making the bundling and fixing more secure.
[0035] As a preferred embodiment, the longitudinal rear end of the horizontal wire harness fixing plate 11 in this embodiment is machined with a rectangular notch 17. The rectangular notch 17 is a clearance space for the protruding end of the AMT wire harness connector 4 in the middle, ensuring that the AMT wire harness has sufficient operating space during installation and disassembly.
[0036] As a preferred embodiment, the horizontal wiring harness fixing plate 11 is arranged on the same plane as the mounting surface of the AMT wiring harness connector 4 installed in the middle of the shift actuator 3, and a pair of side wiring harness fixing brackets 2 are arranged parallel to the mounting surface of the side AMT wiring harness connector 5 installed in the shift actuator 3, so as to prevent the connection between the sensor 7 and the AMT wiring harness connector from becoming loose due to the vibration of the whole vehicle.
[0037] Furthermore, the axis of the central wire harness fixing through hole 15 is perpendicular to the central axis of the wire harness socket of the central AMT wire harness connector 4 in the vertical plane; the axis of the side wire harness fixing through hole 23 is perpendicular to the central axis of the wire harness socket of the side AMT wire harness connector 5 in the horizontal plane, so as to avoid the AMT wire harness and the fixing through hole from being loose due to positional offset.
[0038] As a preferred embodiment, fixing bolts 6 are provided in both the first mounting through hole 14 and the second mounting through hole 16 to ensure the overall bracket is fixedly installed.
[0039] As a preferred embodiment, the central wire harness fixing bracket 1 and the pair of side wire harness fixing brackets 2 are both made of stamped thickened steel plates, so that the overall fixing bracket is not easily deformed under stress.
[0040] In actual operation of this embodiment:
[0041] The central wiring harness fixing bracket 1 is fixedly installed on the shift actuator 3 using fixing bolts 6. The fixing bolts in the second mounting through hole 16 can simultaneously fix the central wiring harness fixing bracket 1 and the shift actuator 3 to the gearbox body. After installation, the central wiring harness fixing through hole 15 corresponds to the central AMT wiring harness connector 4, and the side wiring harness fixing through hole 23 corresponds to the side AMT wiring harness connector 5. The AMT wiring harness installed on the central AMT wiring harness connector 4 is tightened and fixed by passing the wiring harness clamp through the central wiring harness fixing through hole 15, and the AMT wiring harness installed on the side AMT wiring harness connector 5 is tightened and fixed by passing the wiring harness clamp through the side wiring harness fixing through hole 23.
