Problems solved by technology

[0002] In the existing spring tensioning wheel technology, the tensioning arm directly contacts the spring, pushes the spring to expand outwards and presses the spring seat, and the compressed spring seat presses the damping member on the inner wall of the tensioning wheel base. Frictional damping occurs during relative movement, and the pressure value of the spring tension on the spring seat is approximately equal to the tension value of the spring opening. Due to structural limitations, the spring tension on the bearing seat cannot be greatly increased.

Abstract

The invention discloses a spring-extending-type, high-damping and automatic tensioner. The spring-extending-type, high-damping and automatic tensioner comprises a front end gasket, a thrust gasket, a belt pulley, a tension arm, a spring seat, arc-shaped plates, a spring, a base, a central shaft and a spring supporting surface; the tension arm comprises an arm body, an arm pipe, a contact plane and a through hole; the spring seat comprises a first seat body, a second seat body, a third seat body, the first arc-shaped plate and the second arc-shaped plate. According to the structure, the spring-extending-type, high-damping and automatic tensioner provided by the invention has the advantages of high damping ratio, low cost and the like.

Description

technical field [0001] The invention relates to the field of transmission devices for front-end accessories of automobile engines, in particular to a spring-extension type high-damping automatic tensioner. Background technique [0002] In the existing spring tensioning wheel technology, the tensioning arm directly contacts the spring, pushes the spring outward to press the spring seat, and the compressed spring seat presses the damper on the inner wall of the tensioning wheel base. Frictional damping occurs during relative movement of the bearing, and the pressure value of the spring tension on the spring seat is approximately equal to the tension value of the spring opening. Due to structural limitations, the spring tension on the bearing seat cannot be greatly increased. [0003] Therefore, the damping rate (the ratio of the damping friction to the elastic force of the tensioning wheel) is generally lower than 50%, so it is necessary to find a high-damping automatic tensio...
