Background

As an important link in a power assembly, the gearbox plays a role in adjusting the matching between the power output of the engine and the motor and the performance of the whole vehicle under different working conditions. With the increasing severity of the traditional energy problem and the increasing severity of the emission regulations of fuel consumption in recent years, the pure electric vehicle and the hybrid power system formed by adding the electric motor in the transmission are the current development direction of the transmission. The hybrid transmission box needs an integrated motor, so that the original limited space of the front cabin of the automobile is more compact. Pure electric transmission case and hybrid transmission case, the gear number of general demand is less, and the arrangement of shafting in the gearbox and clutch shift system is great different with traditional automatic transmission.

There are three main forms of conventional gearbox shifting mechanisms. A synchronizer-shifting fork gear shifting system commonly used in a manual transmission (MT transmission) is long in power interruption time during gear shifting of a gear shifting mechanism of the type, and poor in driving experience. The second is a planetary gear-wet clutch gear shifting mechanism commonly used in an automatic transmission (AT transmission), the structure of the gear shifting mechanism is complex, the manufacturing cost is high, and the number of meshing points of planetary gears is not beneficial to improving the transmission efficiency of the transmission. The third is a steel belt-belt wheel type gear shifting mechanism commonly used in a Continuously Variable Transmission (CVT), and the belt wheel system of the gear shifting mechanism has large size and is not beneficial to being arranged in a deep hybrid transmission case and a pure electric transmission case.

With the increasing requirements of consumers on the gear shifting comfort and the gear shifting speed of the gearbox, the aims of achieving rapid and stable gear shifting and achieving light structure are always pursued by automobile enterprises.
