901047 steel belt CVT gearbox Pushbelt

The function of the CVT steel belt is to withstand greater torque and at the same time reduce the transmission loss of the car. The key point is to reduce friction and control temperature through lubricating oil.

We all know that the CVT gearbox is a continuously variable transmission, and the key structures are the conical wheels and steel belts (steel chains). So what’s the difference between Chain And Pushbelt? There are the following points. 1. Different suppliers: Currently, the steel belts used in CVT are in the hands of Bosch, and the steel chains are in the hands of Schaeffler. 2. Different structures: Steel strips and tape measures have all been used by everyone. The steel strips are made of several circles using a tape measure, stacked into several layers, and then stuck in small steel pieces. The small Steel Plate are symmetrical, left and right. There is a slot on each side, and something like a tape measure is stuck in the slot. Therefore, the tape measure in the steel belt has to withstand a lot of pressure. Everyone has seen steel chains and bicycle chains. The structure of steel chains is somewhat similar to it, like several chains side by side. 3. Different pressures: Steel belts cannot bear pressure as well as steel chains.
