Abstract EN
This paper proposes a new transmission scheme of hydromechanical continuously variable transmission (HMCVT) for tractors.
The HMCVT has 4 working ranges in each of the front and rear directions.
The speed characteristic and the torque characteristic of HMCVT are theoretically derived.
On the basis of HMCVT power flow direction, the Крейнeс formula is used to calculate the transmission efficiency.
Then, the image analysis method is used to study the influence of parameters on the transmission efficiency of HMCVT, and the main influencing factors are found.
The results of theoretical derivation demonstrate that, by coordinating control of the HST displacement ratio and the engagement conditions of shifting clutches, the stepless speed regulation of HMCVT at the tractor speed of 0–50 km/h can be realized.
The proposed HMCVT has the ability to continuously transmit and change torque over all working ranges.
The overall transmission efficiency of HMCVT is at a high level.
To verify the theoretical derivation, Amesim simulation software is used for the modeling and simulation of HMCVT.
The simulation results are consistent with the theoretical analysis results.
Therefore, the HMCVT proposed in this paper has the advantages of compact structure and high transmission efficiency, and it is suitable for matching tractors.
