TH1754A3 - Gear shift mechanism using cam - Google Patents

Abstract

The cam gear shift mechanism consists of a cam and a spring that controls gear shift, characterized by direct movement of the gear by means of spring pressure and cam pressure, without the need for a gear pin like the internal gear shift mechanism. present Because in some cases there may be limitations, making Able to use gear grapples

Claims (1)

1. The gear shift mechanism using a cam consists of a spring (7) located on the shaft (6) exerts a constant pressure on the gear (5) to the right. But the gear (5) will still not shift to the right. Since there will be a cam (3) to hold the gear, the cam (3) and the spring (7) apply pressure and push the gear (5) to force the gear (5) to the fixed position when the cam (3) rotates clockwise. The cam (3) depresses the gear (5), the pressure from the cam (3) is greater than the spring pressure (7), so the cam (3) can push the gear (5) to slide with the cam pressure (3) when The cam (3) rotates counterclockwise The pressure from the cam (3 years when pressing the gear (5) is reduced. Make the spring pressure (7) large enough to Push the gear (5) to slide it along the pressure line of the spring (7), its characteristic is The gear shift mechanism using this cam (3) is a disc, a steel plate shaped into a circle with a pivot point at one end which is fixed. Attached to the gear jacket Which transmits the force directly to the gear (5), which is a large gear, is assembled in one piece with a small gear, in which the gear (5) is worn on the shaft (6) and can be shifted over the shaft (6). To move on Axles (6) without need for gear shafts and gear shafts
