Description

Technical Field

[0001] This utility model belongs to the field of integrated AMT technology, and relates to exhaust wiring harness, specifically to an exhaust wiring harness for an AMT clutch actuator. Background Technology

[0002] International mainstream AMT (Automatic Mechanical Transmission) systems all adopt integrated AMT, which integrates the transmission controller, shift actuator, and some sensors into one unit, and uses a central pneumatic actuator (CCA) for the clutch actuator. Compared with modular external AMT, integrated AMT has stable reliability, higher economy, and applicability to multiple operating conditions.

[0003] When the AMT is installed into the engine flywheel housing, the CCA is in the extended position and the clutch actuator solenoid valve is in the closed position. There is normal pressure in the CCA air supply passage and CCA cylinder, so the CCA cannot be pushed to the clutch installation position, making the AMT installation difficult.

[0004] The current main solution is to push the CCA to a compressed state when the AMT rolls off the production line, and then install a retaining bracket at the front end of the CCA to keep the CCA in a compressed state. When installing the AMT, the CCA retaining bracket is removed, and the CCA will remain in a negative pressure state for a certain period. However, if the CCA retaining bracket is removed during the AMT installation process, and the CCA reset time has elapsed, causing the CCA to exceed the clutch installation position, it will still lead to installation difficulties. In this case, an AMT diagnostic tool is needed to open the CCA control solenoid valve and then push the CCA to a compressed state; or the CCA mounting bolts can be removed, the CCA pushed to a compressed state, and then the CCA mounting bolts tightened. Both of these methods are complex, time-consuming, and labor-intensive, affecting the OEM's assembly schedule. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an exhaust wiring harness for an AMT clutch actuator, so as to solve the technical problem that the installation difficulty of AMT needs to be further reduced when it is installed on the engine flywheel housing for vehicle assembly.

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

[0007] An exhaust wiring harness for an AMT clutch actuator includes a mobile power supply. The mobile power supply includes a battery positive terminal. One end of the battery positive terminal is connected to the positive wiring harness. The other end of the positive wiring harness is connected to one end of the positive power line in the vehicle connection AMT plug wiring harness. The other end of the positive power line in the vehicle connection AMT plug wiring harness is connected to the positive power terminal in the vehicle connection AMT plug.

[0008] The portable power supply also includes a battery negative terminal, which is connected to one end of a negative wiring harness. The other end of the negative wiring harness is connected to one end of the negative power line in the vehicle AMT connector wiring harness, and the other end of the negative power line in the vehicle AMT connector wiring harness is connected to the negative power terminal in the vehicle AMT connector.

[0009] The battery positive terminal is also connected to one end of the switch harness, the other end of the switch harness is connected to one end of the high-side signal input switch, the other end of the high-side signal input switch is connected to one end of the high-side signal harness, the other end of the high-side signal harness is connected to one end of the signal line in the vehicle connection AMT plug harness, and the other end of the signal line in the vehicle connection AMT plug harness is connected to the signal terminal in the vehicle connection AMT plug.

[0010] This utility model also has the following technical features:

[0011] Specifically, the positive power terminal of the AMT connector in the vehicle is connected to the positive power terminal of the AMT vehicle interface.

[0012] The negative power terminal of the AMT connector for the vehicle is connected to the negative power terminal of the AMT vehicle interface.

[0013] Specifically, the signal terminal in the AMT connector for the vehicle is connected to the high-side signal input interface in the AMT vehicle interface.

[0014] Compared with the prior art, the present invention has the following beneficial technical effects:

[0015] (I) The device of this utility model can supply power to the AMT vehicle interface, thereby supply power to the CCA solenoid valve, and at the same time control the closing or opening of the high-side signal input switch to control the opening and closing of the CCA solenoid valve, thereby realizing manual and rapid compression of CCA. It has a simple structure and is easy to operate, meeting the needs of the clutch actuator.

[0016] (II) The device of this utility model solves the problem that when the AMT is assembled with the vehicle, if the CCA retainer falls off during transportation or the CCA retainer is removed too early, the CCA changes from the retracted state to the extended state, which makes it difficult to install the AMT. It also solves the problem that when the CCA is in the extended state during the gearbox repair stage, it is impossible to compress the CCA, which makes it difficult to install the AMT.

[0017] (III) The device of this utility model is used in AMT with a central clutch actuator (CCA). When it is necessary to compress the CCA, the exhaust wiring harness of the device of this utility model is used to exhaust the CCA, which can easily and effectively compress the CCA.

[0018] (IV) The device of this utility model opens the CCA solenoid valve without the need for service tools or bolt removal, making it easier to compress the CCA to the installation position and facilitating the assembly of the AMT; at the same time, the use of a mobile power supply as the power supply method for the AMT improves the convenience of the device.

[0019] (V) The device of this utility model is equipped with a high-side signal input switch. By controlling the closing or opening of the switch, the high-side signal input is realized, thus avoiding damage to the CCA solenoid valve caused by prolonged energization. Attached Figure Description

[0029] Example:

[0030] This embodiment provides an exhaust wiring harness for an AMT clutch actuator, such as... Figure 1 As shown, the device includes a power bank 1, which includes a battery positive terminal 101. The battery positive terminal 101 is connected to one end of the positive wiring harness 2, and the other end of the positive wiring harness 2 is connected to one end of the positive power line 3 in the vehicle connection AMT plug wiring harness. The other end of the positive power line 3 in the vehicle connection AMT plug wiring harness is connected to the positive power terminal in the vehicle connection AMT plug 4.

[0031] like Figure 1 As shown, the power bank 1 also includes a battery negative terminal 102, which is connected to one end of the negative wiring harness 5. The other end of the negative wiring harness 5 is connected to one end of the negative power line 6 in the vehicle connection AMT plug wiring harness. The other end of the negative power line 6 in the vehicle connection AMT plug wiring harness is connected to the negative power terminal in the vehicle connection AMT plug 4.

[0032] like Figure 1As shown, the positive terminal 101 of the battery is also connected to one end of the switch harness 7, the other end of the switch harness 7 is connected to one end of the high-side signal input switch 8, the other end of the high-side signal input switch 8 is connected to one end of the high-side signal harness 9, the other end of the high-side signal harness 9 is connected to one end of the signal line 10 in the vehicle connection AMT plug harness, and the other end of the signal line 10 in the vehicle connection AMT plug harness is connected to the signal terminal in the vehicle connection AMT plug 4.

[0033] In this embodiment, the vehicle connection AMT plug 4 adopts a vehicle connection AMT plug commonly known in the art.

[0034] As a preferred embodiment, the positive power terminal of the vehicle connection AMT plug 4 is connected to the positive power terminal of the AMT vehicle interface.

[0035] Connect the negative power terminal of the AMT connector 4 in the vehicle to the negative power terminal of the AMT vehicle interface.

[0036] As a preferred embodiment, the signal terminal in the vehicle-connected AMT plug 4 is connected to the high-side signal input interface in the AMT vehicle interface.

[0037] In this embodiment, the positive power terminal of the vehicle-connected AMT plug 4 is connected to the positive power terminal of the AMT vehicle interface, that is, the positive power terminal of the vehicle-connected AMT plug 4 is connected to the power supply port of the control unit in the AMT.

[0038] In this embodiment, the control unit in the AMT uses a known control unit in the AMT.

[0039] In this embodiment, the signal terminal in the vehicle-to-AMT connector 4 is connected to the high-side signal input interface in the AMT vehicle interface, that is, the signal terminal in the vehicle-to-AMT connector 4 is connected to the high-side signal input port of the control unit in the AMT.

[0040] The working principle of the device in this embodiment is as follows:

[0041] When CCA compression is required, connect the AMT connector 4 to the AMT vehicle interface. The AMT is then powered by a 24V power supply 1. Combined with the high-side signal input switch 8, a high-side signal is input to the AMT. Upon receiving the high-side signal, the AMT opens the CCA solenoid valve, compressing or venting the CCA. The operator can manually push the CCA to full compression, then disconnect the high-side signal input switch 8 (i.e., the IO high-side signal is disconnected), closing the CCA solenoid valve. Because the internal air pressure of the CCA is lower than atmospheric pressure, the CCA will remain in this position for a period of time. When the CCA is in the compression position, there is no interference between the CCA release bearing and the clutch release finger, allowing the input shaft to be inserted more easily into the driven plate spline groove, improving the ease of AMT installation.

[0042] In this embodiment, the device supplies power to the AMT via an external 24V mobile power supply, as well as the positive power line 3 and the negative power line 6 in the AMT connector wiring harness. Simultaneously, the mobile power supply 1 provides a high-side signal input to the AMT's IO interface, thereby opening the CCA solenoid valve and connecting the CCA's internal air passage to the ambient air pressure. At this point, the CCA can be easily pushed into the compression state. After being pushed into the compression state, the high-side signal input switch 8 is disconnected, i.e., the signal of the IO interface is inverted, thereby closing the CCA solenoid valve. Due to the reduced air pressure, the CCA will remain in the compression position for a period of time, facilitating the AMT's installation into the vehicle.
