Problems solved by technology

[0003] However, the most important problem in the setting of the electro-hydraulic suspension system at present is how to establish the mechanical displacement and the conversion of the tractor resistance to the electrical signal, that is, there is a lack of a tractor resistance detection device that can accurately sense the tractor. Feedback is implemented in the drag control system, which in turn makes the electro-hydraulic suspension system more sensitive and precise to achieve control

Abstract

The invention discloses a tractor resistance detection device. The device includes a shearing force sensing housing,an electric signal conversion device is arranged in the shearing force sensing housing and is a piezomagnetic-type sensor,and the piezomagnetic-type sensor is connected to an electric signal output control circuit. The provided tractor resistance detection device can precisely senseresistance performed on a tractor and more precisely achieve feedback in a resistance control system,and therefore an electro-hydraulic suspension system achieves control more sensitively and precisely.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a tractor resistance detection device. Background technique [0002] In order to adapt to various farm implements and their different operating conditions, most wheeled tractors currently generally adopt three adjustment methods: force adjustment, position adjustment, and height adjustment. In recent years, foreign tractors have also adopted torque adjustment, pressure adjustment, Comprehensive regulation. The force adjustment is to maintain the tractor engine load stability, and is used to adjust the traction force of the farm implements. It is realized through the resistance control system. The resistance control system is a very important subsystem of the electro-hydraulic suspension system. Traditional tractors use a simple hydraulic device as the driving force for farm implements, and the control part is mechanical. The driver inputs signals in the form of displacement...
