TH660C3 - The gear shift system of the walk-behind tractor uses the internal surface area of the cam. - Google Patents

Abstract

The gear shift system of the walk-behind tractor uses the internal surface area of the cam. Is a development from The gearshift system uses the outer surface of the cam only. Which is widely used today, there is a unique feature. The cam will be grooved inside the cam plate. To make the internal surface area The cam discs are used to regulate the movement of each gear shank in independent of each other.In addition, both the external surface area and the internal surface area of the cam in the same plate may be used at the same time to be able to control the movement of the More gear grapples Where the style or image The body of the cam is not the essence of this invention. This is because the nature or shape of the cam Depending on the nature of the gear Which is the need and purpose of the respective designer, the gearbox shift system of the walk-behind tractor uses the internal surface area of this cam Will allow us to Developed walk-behind tractor with a larger number of gears. There are more sophisticated gearing systems and cadence, with walk-behind tractor operators able to leverage the traditional gear lever. And there is no need to increase the number Plate of cam It can also be applied in ride-on tractors, tractors, crawler trucks, and other similar gear-shifting machines.

Claims (2)

1. The gear-shift system of the walk-behind tractor uses the inner surface of the cam, consisting of a eccentric ball in which the inside of the cam is grooved To create the surface area inside the cam plate, camshaft axis, gear lever, spring, gear pin, gear shaft. Serves to control the gear shift of the walk-behind tractor. When a walker operator wants to change gears, a walker sneezes. The user will move the gear lever, the surface area within the groove of this cam. Will push the gear pin to move along the gear rack shaft While the spring will push the claw. Gear to the ginger roller, the leg claw that gear Stay attached to the surface area inside the cam groove at all times. The gear shifting system uses the internal surface area of this cam. May use the external surface area of the cam With or without using the surface area inside the cam This will allow the cam to control the action. Multiple gear grippers can be freely connected. Additionally, each gear grapple may be on the gear shaft. Same or not 2. The gear shifting system of the walk-behind tractor uses the internal surface area of the cam as per item 1, which is a mechanism for Change gears of ride-on tractors, tractors, and / or crawler vehicles.
