Abstract:

Information construction technology is a developing trend of construction machine. As a typical earthwork machine, bulldozer usually works with high loads and shift frequently in complex situations and bad surrounding. The existing machines are mostly equipped with manual shift transmissions, which are inefficient and need driver's hard work. The intelligent control of bulldozer's transmission has many advantages: ①It will release the drivers from hard work, make the drive easy and comfortable; ②The transmission will match with engines better during running, which will improve the dynamic performance and efficiency of the machines and reduce the discharge for saving energy and protecting environment; ③The intelligent control system will decrease the crash of the shift and prolong the life of the transmission; ④It will become the foundation of information construction. In this paper, some improvements are made on the basis of the traditional hydraulic control system and a fully new electronic control system for bulldozer's transmission is developed. On this base, the hardware of the control system is build up. According to the requirement of bulldozer's work situation, a suitable shift strategy is scheduled. After a series of simulation studies and tests, the system is verified and modified. The result shows that the control system of the transmission is effective.
