Automatic gear shifting control method of wheel type excavator during travelling
The invention discloses an automatic gear shifting control method of a wheel type excavator during travelling. The method involves a high-speed gear and a low-speed gear, and is characterized in thatthe travelling speed and the running pump pressure value of the excavator are collected, a controller is used for carrying out comparison operation, and when the travelling speed and the running pumppressure value meet preset conditions, a transmission mode of a gear box is controlled to be the low-speed gear or the high-speed gear. According to the method, certain absorption, attenuation and buffering functions can be played, and the impact and dynamic load on an engine are greatly reduced; and due to the good self-adaptive control, the gear shifting is realized automatically, the gear shifting times in the running process are greatly reduced, the excavator is easily started and stable in gear shifting, and the operation convenience is increased.
本发明公开了一种轮式挖掘机的行走自动换挡控制方法，包括高速和低速两种档位，其特征在于：采集挖掘机的行走速度和行驶泵压力值，通过控制器进行比对运算，当行走速度和行驶泵压力值满足预设条件时，控制变速箱传动模式为低速挡或高速挡。本发明可以起到一定的吸收、衰减和缓冲作用，大大减少发动机的冲击和动载荷；良好的自适应控制使换档实现自动化，大大减少了行驶过程中的换档次数，且使挖掘机起步容易、换档平稳，增加了操纵轻便性。
