Abstract

The invention provides a method for improving the climbing ability of a support carrying vehicle. The method is characterized in that a front auxiliary wheel is changed into a driving wheel, the front wheel is used as the driving wheel to work only when climbing a slope, and the front wheel is not used as the driving wheel on a flat road surface; a group of auxiliary driving wheels are additionally arranged, and a hydraulic oil cylinder and a connecting rod mechanism are used for achieving stretching and retracting of the auxiliary driving wheels; and the driving torque of a travelling motor is controlled, and the rotating speed of a diesel engine and the maximum displacement of the travelling motor are controlled correspondingly. The method has the advantages that (1) the economical efficiency is guaranteed while the climbing ability is enhanced, and the fuel consumption is reduced as much as possible; (2) the adhesion coefficient is increased, the vertical load driven by each shaft is redistributed and the adhesion coefficient is improved; and (3) the situation that the driving wheels slip on a slippery road surface under a mine is effectively avoided.

Description

technical field [0001] The invention belongs to the field of coal mine machinery, and in particular relates to a hydraulic transmission system of a support transport vehicle. Background technique [0002] Coal is one of the world's three major energy sources. In China, the status of coal is even more prominent. China is the world's largest coal producer and also the world's largest coal consumer. It is one of the few countries where coal is the main energy source. The proportion of coal in China's energy production has been maintained at more than 50%, and with the decline in the proportion of crude oil production, the importance of raw coal production has become more and more significant. [0003] With the rapid development of my country's economy and the upgrading of coal mechanized mining, the mechanization and modernization of large and medium-sized coal mines in China are getting higher and higher. The direction of mechanization is developing, and at the same time, th...
