Description

Technical Field

[0001] The utility model relates to an AMT wiring harness, in particular to an integrated AMT one-piece sensor wiring harness. Background Art

[0002] Compared with manual transmission, the automatic mechanical transmission (AMT) needs to connect the transmission controller (TCU), clutch actuator, gear selector actuator, solenoid valve, sensor and other components together through the wiring harness assembly, and conduct electricity and transmit signals to the electronic control components through the wiring harness assembly, thereby realizing automatic disengagement and engagement of the clutch and automatic shifting of the transmission.

[0003] Chinese patent CN219659078U discloses a wiring harness for a truck automatic transmission. By using sequentially distributed butt connectors, the entire wiring harness is fixedly connected along the outer extension of the transmission body through a wiring harness fixing bracket, resulting in a reasonable spatial layout. However, its disadvantage is that the wiring harness is connected to the sensor via a connector, specifically the female end of the wiring harness docks with the male end of the sensor installed on the transmission. For vehicles used in harsh working environments and bumpy roads, the integrated wiring harness connectors in the aftermarket have been found to be prone to loosening and poor contact under prolonged vibration conditions, resulting in occasional open circuit failures and sensor signal loss, affecting the operation of the transmission and the entire vehicle.

[0010] The controller plug connector is plugged into the controller plug to realize the controller supplying power to the displacement sensor and the rotation speed sensor, and the signal transmission between the controller and the displacement sensor and the rotation speed sensor.

[0011] Furthermore, there are two wiring harness brackets, namely a first wiring harness bracket and a second wiring harness bracket; the first binding strap fixes the first branch line on the first wiring harness bracket, and the second binding strap fixes the second branch line on the second wiring harness bracket.

[0012] Furthermore, the wiring harness fixing member also includes a first fixing pin and a second fixing pin; the first fixing pin is installed in a corresponding slot on the gearbox housing, and its clamp is fixedly connected to the first branch line; the second fixing pin is installed in a corresponding slot on the gearbox housing, and its clamp is fixedly connected to the second branch line.
