Moving plate continuously variable transmission belt

Abstract

A continuously variable transmission driving belt with sliding vanes comprises annular bearing bodies and transverse parts installed on the annular bearing bodies and is characterized in that the transverse parts are continuously arranged and mounted on the annular bearing bodies and can move transversely leftwards and rightwards on the axes of the annular bearing bodies so that tooth profiles with the arbitrary shapes and sizes can be formed on the surfaces of the two sides of the driving belt. The continuously variable transmission driving belt with the sliding vanes has the beneficial effects that tooth engagement and continuously variable driving can be achieved, and the defects that a common continuously variable transmission driving belt driven by frictional force is small in transmitted torque, low in bearing capacity, poor in overload resistant and impact resistant performance and large in sliding rate, the mechanical efficiency is low, the power loss is large, transmitted power is limited, and the application range is limited are overcome.

[0001] Technical field [0002] The invention relates to a power transmission belt, in particular to a power transmission belt suitable for a continuously variable transmission. Background technique [0003] At present, the transmission belt or chain of continuously variable transmission mostly adopts friction transmission, because of its small transmission torque, low load-carrying capacity, poor anti-overload and anti-impact performance, large slip rate, and low mechanical efficiency; some also have pulsating output and discontinuous power flow. Phenomenon; transmission of power needs to increase the pressure on the transmission belt to increase the friction, thus causing a large power loss, and causing the load of each bearing to increase, and the bearing is easy to be damaged; the effective contact surface for power transmission is small, Theoretically, it is line contact or point contact, and the local stress is large, which may easily cause scratches or glue on the worki...

Phenomenon; transmission of power needs to increase the pressure on the transmission belt to increase the friction, thus causing a large power loss, and causing the load of each bearing to increase, and the bearing is easy to be damaged; the effective contact surface for power transmission is small, Theoretically, it is line contact or point contact, and the local stress is large, which may easily lead to scratches or gluing of the working surface, limited transmission power, and short life, which limits the scope of application

The slide chain relies on the groove sprocket and the slide chain to transmit power in a quasi-engagement manner. It has the advantages of low sliding rate, precise transmission, wear resistance, and high impact capacity. However, because the slide of the slide chain is on the slide chain It is a non-continuous arrangement. When the sliders of the slider chain mesh with the grooves on the surface of the grooved sprocket, only one or a few pieces may be stressed, so it is easy to cause the sliders to break and damage
