Gear shifting control system, bulldozer and gear shifting control method
The invention relates to the technical field of bulldozers, in particular to a gear shifting control system, a bulldozer and a gear shifting control method.The gear shifting control system comprises an engine and a gearbox, a clutch is arranged between the engine and the gearbox, an angle sensor is arranged on a pedal of the clutch, and a stroke sensor is arranged on a gear shifting fork shaft of the gearbox; the hydraulic pump can drive the hydraulic motor to rotate forwards or backwards so as to selectively increase or decrease the input rotating speed of the gearbox; and the controller is electrically connected with the hydraulic pump, the hydraulic motor, the angle sensor and the stroke sensor. By arranging the hydraulic pump and the hydraulic motor, during normal operation, the hydraulic pump and the hydraulic motor are zero in displacement, engine power is input into the gearbox after passing through the clutch and is input into the driving wheels after passing through the gearbox and final transmission, and the whole machine is driven to walk; when gear shifting is needed, the controller can control the rotating speed input into the gearbox by adjusting the displacement of the hydraulic pump and the displacement of the hydraulic motor.
本发明涉及推土机技术领域，尤其涉及一种换挡控制系统、推土机及换挡控制方法，其中换挡控制系统包括发动机和变速箱，发动机和变速箱之间设有离合器，离合器的踏板上设置有角度传感器，变速箱的换挡叉轴上设置有行程传感器，还包括液压泵和液压马达，液压泵能够驱动液压马达正转或反转以选择性地增大或减小变速箱的输入转速；还包括控制器，控制器与液压泵、液压马达、角度传感器和行程传感器电连接。本发明通过设置液压泵和液压马达，正常作业时，液压泵和液压马达零排量，发动机动力通过离合器后输入变速箱，经变速箱、终传动后输入驱动轮，驱动整机行走；需要换挡时，控制器能够通过调整液压泵和液压马达的排量，控制输入变速箱的转速。
