Background
In recent years, commercial vehicle drivers are younger, higher requirements are put forward on the driving convenience, comfort, economy and the like of the commercial vehicles, meanwhile, the medium and light truck market becomes an important business growth point of the department, and in order to meet market demands, the department develops an AMT (automated mechanical transmission) of an F6JZ45AM/BM series and an F8JZ95CM/MM series. Because the existing installation experience of the gearbox in a host factory and a service station is less, the operation process mostly follows the original mechanical box process, and meanwhile, the installation process is possibly not very careful, the problem that one end of a push rod or a supporting pin in a clutch actuating mechanism of the gearbox is separated due to improper installation can occur. The current means is to ensure that the ball head of the push rod of the clutch actuating mechanism cannot be disengaged from a ball socket of a release fork by redesigning a fork liner in the mechanical aspect. However, the position of the push rod of the clutch actuator needs to be monitored from the software monitoring direction, so that the push rod is ensured to be in an undeployed state. Once the push rod is disengaged, fault feedback is reported in software through a CAN signal.

Detailed Description
The present invention will now be described in further detail with reference to specific examples, which are intended to be illustrative, but not limiting, of the invention.
As shown in fig. 1 and 2, the position of the release bearing 2 is different based on the gearbox requirement of different manufacturers, so that the length of the supporting pin can be adjusted to ensure that the push rod position 3 of the clutch actuator of different manufacturers is in an almost identical position. The value of the clutch actuator push rod position 3 is set to a standard. And a range is set on the basis of this criterion, and the range beyond which the clutch actuator push rod comes out, or the support pin comes out, is recognized as the clutch actuator push rod comes out, as long as the initial position of the clutch actuator push rod is after installation. The initial and subsequent positions of the clutch actuator push rod are measured by displacement sensors (fig. 2) in the clutch actuator. Then the displacement sensor transmits data into a transmission case TCU through a J1939 message CAN signal (an automobile communication signal), software in the transmission case TCU judges whether the data has problems, if the data exceeds a set range, the data is judged to have a fault, the J1939 message CAN signal is transmitted to the instrument through the whole automobile CAN, and an alarm lamp of the transmission case on the instrument gives an alarm. At present, the method does not monitor the clutch actuating mechanism push rod or support pin from the aspect of software, and once the method is implemented, the method can directly give a fault alarm and lock the problem once the fault occurs.
The invention relates to a position deviation alarm system for a push rod of a clutch actuating mechanism, which comprises a displacement sensor; the displacement sensor is arranged in the clutch actuating mechanism and used for monitoring the length of the supporting pin; the displacement sensor is in data connection with a transmission case TCU; the gearbox TCU is used for judging whether the length of the support pin meets a preset length or not; the TCU of the gearbox is in data connection with a CAN of the whole vehicle, and a gearbox alarm lamp of a CAN control instrument of the whole vehicle gives an alarm. In this embodiment, the displacement sensor is a linear displacement sensor.
As shown in fig. 3, the method for alarming the position deviation of the push rod of the clutch actuator according to the invention comprises the following processes,
the displacement sensor monitors the length of the supporting pin to generate length data; the displacement sensor transmits the length data to the transmission TCU; the TCU of the gearbox judges whether the length data is in a preset range; when the length data is not in the preset range, the whole vehicle CAN transmits the fault to the instrument and gives an alarm through the instrument.
The gearbox TCU is provided with a comparison module, the length data of the supporting pin are preset in the comparison module, the comparison module compares the length data monitored by the displacement sensor with the preset length data, and when the monitored length data exceed the preset length data range, the whole CAN carries out fault alarm.
