[0003] The automatic shift control performance of unmanned tractors determines the matching effect of tractor automatic driving speed and power. At present, there is no standard for automatic shift control of unmanned driving. Applicable to the modification scheme of automatic shift control of different tractors; at the same time, part of the gear detection needs to be calculated through the reduction ratio, and it is necessary to consider whether the calculated value of the sensor is consistent with the actual value due to the gear gap of the reducer

The invention relates to an automatic gear shifting universal device of an unmanned tractor. The device comprises a longitudinal driving device and a transverse driving device, wherein the longitudinal driving device is arranged below a tractor seat, and the transverse driving device is arranged on the side surface of a fender on the right side of the tractor; the longitudinal driving device comprises a longitudinal rectangular gear shifting frame and a longitudinal electric push rod, the longitudinal rectangular gear shifting frame sleeves a gear rod, and the longitudinal rectangular gear shifting frame is fixedly connected with the free end of the longitudinal electric push rod through a bolt; the transverse driving device comprises a transverse rectangular gear shifting frame and a transverse electric push rod, the transverse rectangular gear shifting frame sleeves the gear rod, and the transverse rectangular gear shifting frame is fixedly connected with the free end of the transverse electric push rod through a bolt; the free end of the longitudinal electric push rod and the free end of the transverse electric push rod are respectively connected with the free end of a linear displacement sensor; the longitudinal rectangular gear shifting frame and the transverse rectangular gear shifting frame vertically sleeve the gear rod from bottom to top. Automatic gear shifting of theunmanned tractor is accurately controlled, the automatic gear shifting universal device is stable, reliable and convenient to install, the original structure of the tractor is not changed, and universality is achieved.
Description
technical field [0001] The invention relates to a universal device for automatic gear shifting of an unmanned tractor, which belongs to the field of intelligent research on agricultural machinery equipment. Background technique [0002] At present, my country's agricultural modernization is accelerating the development, large-scale management of rural land, large transfer of agricultural labor force, higher technical requirements for agricultural machinery and equipment, and huge demand for products. It is of great significance to accelerate the development of intelligent agricultural machinery unmanned driving technology, improve the supply capacity of agricultural machinery and equipment, narrow the gap with foreign mainstream products, support the development of modern agriculture, and ensure food and industrial security. [0003] The automatic shift control performance of unmanned tractors determines the matching effect of tractor automatic driving speed and power. At pr...
