Continuously variable transmission driving chain composited with push blocks

Abstract

The invention discloses a continuously variable transmission driving chain composited with push blocks. The chain comprises a plurality of chain links and chain pins connecting the plurality of links;and the chain is characterized in that the chain links are composed of chain link piece sets and push blocks which are integrally arranged with the chain link piece sets, and a contact part is formedby the front surface of each push block and the adjacent push block at the front end is used for conveying power under the extruding pushing action of the chain links. The Continuously variable transmission driving chain has the beneficial effects that the driving chain is connected by the chain links, the bending degree of the chain is large, and the chain is not prone to break; the contact areabetween the push blocks and conical discs is large, the push blocks are divided into wide push blocks and narrow push blocks, the contact surface of the driving chain and each conical disc is in a tooth shape, the grasping force of the driving chain and the surfaces of the conical discs is increased, materials are saved, and the manufacturing cost is reduced; anti-skid lines are arranged on the contact surfaces of the push blocks and the conical discs, the grasping force of the contact surface of the push blocks and the conical discs and the surfaces of the conical discs and the capability ofbreaking oil films at the surfaces of the conical discs are improved, and the anti-skid and heat dissipation effects are good; and the driving efficiency of the driving chain is high, and the energyconsumption, the failure rate and the manufacturing cost of the driving chain are low.

Description

Technical field [0001] The invention relates to a power transmission chain, in particular to a power transmission chain suitable for a continuously variable transmission. Background technique [0002] At present, there are mainly two types of power transmission chains or belts used in continuously variable transmissions, one is a pull type transmission chain, and the other is a push type transmission chain. The pull type transmission chain relies on the contact between the end face of the connecting pin of the chain and the conical surface of the transmission cone of the continuously variable transmission, and pulls the cone to transmit power; while the push type transmission chain relies on the basically continuous arrangement installed on the flexible steel belt ring. The end surfaces on both sides of the push piece are in contact with the conical surface of the drive cone of the continuously variable transmission, and the push piece pushes against each other, thereby push...

AI Technical Summary

Problems solved by technology

Pull-type transmission chain and push-type transmission chain have their own advantages and disadvantages. The chain links of pull-type transmission chain are relatively strong, not easy to break, and the bending degree of the chain is relatively large. The contact with the conical surface of the transmission cone of the continuously variable transmission transmits power, and the end surface area of ​​the connecting pin of the chain is small, which is easy to slip, and it is easy to cause damage to the continuously variable transmission due to the wear of the end surface of the connecting pin; and the push type transmission chain relies on installation On the flexible steel belt ring, the end faces on both sides of the push pieces arranged continuously are in contact with the conical surface of the transmission cone of the continuously variable transmission to transmit power. The contact area between the push piece and the cone is large, the transmission efficiency is high, and it is not easy to slip. However, the flexible steel belt ring is easy to fatigue and fracture, causing damage to the continuously variable transmission. In addition, the push-type transmission chain cannot be bent excessively, and the transmission is smaller than the push-type transmission chain.
