is driven by air pressure. Due to the structural characteristics of the gearbox, the auxiliary box mainly realizes the conversion of high and low gears, which is driven by air pressure. The gearbox, one of the auto parts, is a device that changes the speed ratio and the direction of movement.
auxiliary transmission is an additional transmission attached to the main transmission. Its function is to increase the number of gears of the transmission and expand the range of transmission ratios. The following is a specific introduction about the auxiliary transmission: 1. Application: In heavy-duty vehicles, due to the large load changes, the transmission ratio range of the transmission is also required to be large. Generally, the five-speed transmission is difficult to meet the requirements. With the auxiliary transmission, the five-speed main transmission can be changed to a six-speed, ten-speed or even twenty-speed transmission. Increasing the auxiliary transmission can reduce fuel consumption, but the operation must be skilled to play a role. 2. Structure: The simple transmission has the advantages of high efficiency, simple structure and convenient use, but the number of gears is small, and the range of change is small. It is only suitable for some lathe workers with few gears. If the range is increased, the size of the transmission will be increased and the shaft span will be increased. In order to increase the number of gears and not make the shaft span too large, a composed transmission can be adopted.
