Intelligent differential lock integrated system

Abstract

The invention discloses an intelligent differential lock integrated system. The integrated system is characterized in that a gas path of the whole vehicle is connected to a differential assembly through a differential lock electromagnetic valve, wherein a vehicle body control module is used for judging current vehicle speed and transmitting the current vehicle speed to a chassis control module after acquiring a pulse signal of a vehicle speed sensor through a combined instrument; the chassis control module is used for controlling the differential lock electromagnetic valve to be opened and closed to control the switching time of the differential assembly. According to the intelligent differential lock integrated system with the structure, the differential lock electromagnetic valve is logically controlled; a detection device is used for judging whether the vehicle is inconsistent with a differential lock operating standard or not according to the running state of the vehicle, and executing mode switching; a control logic and a judgment parameter can be set by virtue of computer software, and a plurality of completely new functions of vehicle state identification, driving intension judgment, adaptive protection, parametric regulation, failure diagnosis and the like of a differential lock are realized, so that the misoperation risk is reduced, and the reliability of the differential lock and other chassis parts can be remarkably improved.

Description

technical field [0001] The invention relates to the field of design and manufacture of heavy trucks, in particular to an integrated system of intelligent differential locks. Background technique [0002] Transport vehicles, especially heavy-duty trucks, often go in and out of soft, muddy and low-lying potholes due to their harsh working environment. When the wheels get stuck in mud or mounds, the driving wheels will slip due to loss of ground adhesion. No matter how much the accelerator is opened, the vehicle cannot move forward, and the non-slipping wheels do not rotate, while the slipping driving wheels just idle at high speed. In order to get rid of this predicament, the vehicle driver needs to control the system to open the differential lock on the drive axle, so that the left and right axle shafts are forcibly locked, and the driving force can be evenly distributed to each drive shaft and drive wheels to help the vehicle get out of trouble. , and close the differential...

AI Technical Summary

Problems solved by technology

The driver uses the rocker switch to control the air on and off of the differential lock solenoid valve. If the driver does not operate properly, the differential will be forced to lock when it is working, which will easily cause the differential to be damaged and the vehicle to stop.

In addition, the cost of replacing the differential is high and the time is long, which brings a lot of inconvenience and troubles to customers and after-sales service work

[0005] In view of the above problems, a new type of intelligent differential lock integrated system is provided, which can make up for the shortcomings or deficiencies of the existing control system in terms of structure and function when accurately controlling the differential lock switch.
