Transmission structure:
The simple transmission has the advantages of high efficiency, simple structure, and convenient use, but it has few gears and a small variation range of I (small field of traction and speed).
If the range of i is increased, the transmission size will be enlarged, and the axle span will be increased.
A composite transmission can be used to increase the number of gears without making the axle span too large.
The so-called component transmission is usually composed of two simple communications. The one with more gears is the main transmission, and the less is the auxiliary information.
Transmission classification:
First, according to the change in the transmission ratio, the transmission can be divided into three types: stepped, stepless, and comprehensive.
Stepped transmission: There are several selectable fixed transmission ratios geared.
It can be divided into ordinary gear transmissions with fixed gear axes and planetary gear transmissions in which some gears (planetary gears) axis rotate.
The stepped transmission is the most widely used one. It adopts gear transmission and has several fixed value transmission ratios.
According to the different types of gear trains used, there are two types of axially fixed transmissions (standard transmissions) and axial rotary transmissions (planetary gear transmissions).
Continuously variable transmission: The transmission ratio can be continuously changed within a specific range, and the common ones are hydraulic, mechanical, and electric.
Continuously variable transmission refers to a system that can constantly obtain any gear ratio within the transmission range.
The optimal match between the drive train and the engine operating conditions can be obtained through the continuously variable transmission.
Standard continuously variable transmissions include hydromechanical continuously variable transmissions and metal belt continuously variable transmissions (VDT-CVT).
Integrated transmission comprises stepped information and a continuously variable transmission.
Its transmission ratio can be constantly changed within the range of several segments between the maximum value and the minimum value.
The integrated transmission refers to a piece of hydromechanical information composed of a hydraulic torque converter and a gear-type stepped transmission.
Its transmission ratio can be continuously changed within a few intermittent ranges between the maximum and minimum values. More applications.
Second, the transmission can be divided into three types: forced operation and semi-automatic operation according to the operation mode.
Forced-operated transmission: The driver directly manipulates the shift lever to shift gears.Semi-automatic operation transmission: It can be divided into two categories, one is the automatic shifting of some gears and manual (mandatory) shifting of some gears; the other is to select the gear with the button in advance and release the accelerator pedal When the actuator itself shifts the gear.
