Screw reducer spring synchronizer

Abstract

A screw variable-diameter spring synchronizer comprises a driven shaft with threads and a driven shaft wheel screwed to the driven shaft. A left auxiliary wheel, a left buffer wheel, a left catch wheel and a left variable-diameter spring are arranged on the left side of the driven shaft wheel. A right auxiliary wheel, a right buffer wheel, a right catch wheel and a right variable-diameter spring are arranged on the right side of the driven shaft wheel. The screw variable-diameter spring synchronizer is characterized in that internal threads are arranged in a center hole of the driven shaft wheel and matched with external threads on the driven shaft, the left auxiliary wheel is fixedly arranged on the left side face of the driven shaft wheel, the left buffer wheel is arranged on the left side of the left auxiliary wheel, the left catch wheel is arranged on the left side face of the left buffer wheel, a right expanded metal smooth surface outer cylinder of the left catch wheel is arranged on the right side of the left catch wheel in an extending mode, a metal smooth surface inner cylinder for a center hole of the left buffer wheel is fixedly arranged at the center hole of the left buffer wheel, the right expanded metal smooth surface outer cylinder of the left catch wheel is sleeved with the metal smooth surface inner cylinder for the center hole of the left buffer wheel, and the metal smooth surface inner cylinder for the center hole of the left buffer wheel can rotate around the right expanded metal smooth surface outer cylinder of the left catch wheel.

Description

technical field [0001] The invention relates to a screw variable-diameter spring synchronizer, which is suitable for all automobile transmissions and belongs to the technical field of automobile transmissions. Background technique [0002] Since the birth of automobiles, human beings have never stopped studying the clutches of automobiles. People have developed a variety of automobile clutches. The most important thing in the clutch is the synchronizer, and these synchronizers cannot achieve gear transmission. Efficient transmission efficiency; Wei Boqing's invention "201510000063.1 Screw Spring Synchronizer" uses the clever combination of screw and spring to form a synchronizer that not only has cushioning but no obvious frustration, but also achieves efficient power transmission like gear transmission efficiency, but this synchronization Due to the force of the two springs, the driven shaft wheel in the middle will have greater resistance when it starts to rotate, thus aff...

[0002] Since the birth of automobiles, human beings have never stopped studying the clutches of automobiles. People have developed a variety of automobile clutches. The most important thing in the clutch is the synchronizer, and these synchronizers cannot achieve gear transmission. Efficient transmission efficiency; Wei Boqing's invention "201510000063.1 Screw Spring Synchronizer" uses the clever combination of screw and spring to form a synchronizer that not only has cushioning but no obvious frustration, but also achieves efficient power transmission like gear transmission efficiency, but this synchronization Due to the force of the two springs, the driven shaft wheel in the middle will have greater resistance when it starts to rotate, thus affecting the engagement of the driven shaft wheel with the driving wheel input by external force. When using the buffer wheel, since the friction with the buffer wheel will cause greater wear and tear on the buffer wheel, the present invention makes improvements based on these two defects
