Abstract

The invention discloses a shift control device based on a twin-turbo torque converter planetary gearbox, and belongs to the fields of construction machinery and automatic control. The device comprises an electrical control device, an input secondary gear clutch and a hydraulic control device. The electrical control device comprises a gear proximity switch, a secondary gear switch solenoid valve and a two-axis shift solenoid valve which are connected with a two-axis improved controller through harnesses. The secondary gear switch solenoid valve and the two-axis shift solenoid valve are located in the hydraulic control device, and the gear proximity switch is arranged in the planetary gearbox. By the aid of the device, the problems that shift impact of planetary gearboxes of construction machinery of a loader and the like in the prior art is large is solved, and the method is mainly applied in automatic shift control of the twin-turbo torque converter planetary gearbox.

Description

technical field [0001] The invention belongs to the field of engineering machinery and automatic control, and in particular relates to a shift control device based on a twin-turbine torque converter planetary gearbox. Background technique [0002] Loaders are mainly used for shoveling and loading operations. In order to ensure the efficient operation, frequent start→stop, forward→reverse shifts are required. Therefore, the gear control system of the loader gearbox is particularly important. For example, it is installed in a Construction machinery such as loaders with planetary mechanical gearboxes. [0003] The gear control system of planetary mechanical transmission of loader is generally mainly composed of gear handle, flexible shaft, shift control valve, and transmission system; The body is heavy and the torque is large. In the traditional shifting process, when shifting from one gear to another, due to the neutral position, the gearbox input primary and secondary gear a...
