Embodiment 1
[0066] The free stroke of the clutch pedal is required to be 45mm, and the total stroke of the clutch pedal is 225mm; the input parameters of Admas are that the total stroke of the clutch pedal is 225mm, the initial spring force of the booster spring mechanism (calculated according to the tractor design manual), and the spring stiffness (according to the tractor) Design manual), initial spring force of torsion spring (calculated according to tractor design manual), torsion angular stiffness of torsion spring (calculated according to tractor design manual). It can be seen from the analysis diagram that Image 6 The initial pedal return force of the clutch pedal is 35N, the final pedal assist of the clutch pedal is 75N, and the pedal stroke with zero assist value is 95mm; the initial force of the invention is easy to perceive, the pedal returns smoothly, and the final assist effect is obvious. The characteristics of the present invention, such as the pedal return force, the fina...

The invention provides a clutch pedal power-assisted mechanism and a tractor and relates to the technical field of agricultural machinery equipment. The clutch pedal power-assisted mechanism comprisesa rotating shaft, a pedal assembly and a power-assisted elastic component, the pedal assembly is rotatably connected with the rotating shaft, the power-assisted elastic component comprises a rocker arm, a first power-assisted elastic part and a second power-assisted elastic part, and the rocker arm is connected with the pedal assembly and connected with the first power-assisted elastic part through a rotary hinge supporting point and can rotate around axis of the rotating shaft; the first power-assisted elastic part is connected with a fixed hinge supporting point fixed on a vehicle body; along the axis direction of the rotating shaft, the rotary hinge supporting point when the pedal assembly is at an initial position and the rotary hinge supporting point when the pedal assembly is at a final position are positioned on two sides of a straight line connecting the rotating shaft and the fixed hinge supporting point; the second power-assisted elastic part is connected with the pedal assembly and used for providing assisting power. By the clutch pedal power-assisted mechanism, better matching between a power-assisted arrangement mode and clutch separation characteristics and clutch operation movement characteristics can be realized, operation force of a pedal can be reduced effectively, and operation comfort can be improved.
Description
technical field [0001] The invention relates to the technical field of agricultural machinery and equipment, in particular to a clutch pedal booster mechanism and a tractor. Background technique [0002] At present, the tractor needs to shift gears frequently during the working process, so the clutch pedal needs to be stepped on frequently. The tractor has a heavy clutch operating force due to the complex operating conditions and the continuous upgrade of horsepower. If the clutch control assist mechanism is not added, it will be difficult to meet people's needs for the comfort of the tractor, and it will cause long-term fatigue and reduce work efficiency. [0003] At present, most of the tractor power-assisting methods use an external servo mechanism (air pump or hydraulic pump) to reduce the clutch pedal force. However, using an external servo mechanism is difficult to arrange and complex to assemble, and at the same time increases the manufacturing cost of the tractor. ...
