Problems solved by technology

It is the transmission that generates friction at the contact point, so it has many disadvantages
When used in a motor vehicle, the chain or belt slips on the sprocket, so the efficiency is low and the transmission torque is small. To transmit a large torque, the friction between the chain and the wheel must be increased, so that more work is consumed in friction and power consumption increases. Sometimes Difficult to start after parking, loud noise when changing gears, unstable transmission, and short belt life, so CVT transmissions are only used in small cars now

Embodiment Construction

[0014] The installation structure of active and driven expansion and contraction gears is that the wheel hub 17 of the linear groove disc 21 on the shaft 13 is fixedly installed with screws 20 or with keys, and another same linear groove disc is fixedly installed on its corresponding surface. Shaped protruding portion, on its two linear groove discs, 4 or 4 or more equally distributed linear grooves 18 are symmetrically arranged respectively, and its length is long when the speed change ratio is large, and hour is short, and movable teeth 30 are placed on its two linear grooves. The tooth arm 33 and the tooth arm on the other side, the outer two sides of the linear groove disc are respectively equipped with arc groove discs 21. The number and distribution angle of the arc grooves 22 of the two arc groove discs are the same as the linear grooves of the straight groove discs. The number is the same as the angle, and the length of its arc groove is made by the longest arc groove c...

Abstract

The invention relates to a mechanical type continuously variable transmission device. In the tooth meshing transmission non-stage transmission, two increasing-decreasing gears with gear diameters which are variable as required are used as speed ratio changers, when the gear diameter of one increasing-decreasing gear increases, the gear diameter of the other increasing-decreasing gear decreases the same length correspondingly at the same time, and the two gears are driven by the meshing of a toothed chain. The non-stage transmission overcomes the defects of the friction type continuously variable transmission (CVT) such as small drive moment, chain and wheel slippage, small starting moment, high gear shift power consumption, and really realizes the stepless speed change of tooth meshing transmission. The tooth meshing transmission non-stage transmission has the advantages of big drive torsional moment, small volume, and simple structure, and can be applied to various large and small-sized machines in large and small-sized vehicles or fixed occasions.

Description

Technical field: [0001] The invention relates to a mechanical continuously variable transmission device. Background technique: [0002] The current mechanical continuously variable transmission (CVT) is friction type, chain type, belt type, etc. It is the contact that generates friction for transmission, so it has many disadvantages. When used in a motor vehicle, the chain or belt slips on the sprocket, so the efficiency is low and the transmission torque is small. To transmit a large torque, the friction between the chain and the wheel must be increased, so that more work is consumed in friction and power consumption increases. Sometimes It is difficult to start after parking, the noise is loud when changing gears, the transmission is unstable, and the life of the belt is short. Therefore, CVT transmissions are only used in small cars now. Invention content: [0003] Many shortcomings of the above-mentioned CVT transmission are caused by friction transmission torque, so...
