Embodiment Construction

[0064] Referring to FIG. 1, a walk-behind working machine 10, such as a lawnmower, includes a body 11 having a pair of front left and right front wheels 12, 12 (only the left wheel is shown). The fuselage 11 also has a pair of left and right rear wheels 13, 13 (drive wheels) positioned at the rear. An engine 14 is housed on the fuselage 11 top. Position one below the fuselage 11 middle part and be used for cutting grass 82 (seeing Figure 6 ) of the blade 16. The fuselage 11 also includes a transmission 20 positioned on the inside of the rear. The body 11 also includes a pair of left and right handles 50L, 50R protruding rearwardly therefrom. The fuselage 11 is operated by means of these handles 50L, 50R.

[0065] The engine 14 is a drive source for driving the rear wheels 13 , 13 and the blade 16 . In more detail, the engine 14 includes a downwardly projecting output shaft 15 . The output shaft 15 is connected to the blade 16 via a work switching clutch 42 . The output...

Abstract

A walking working machine includes an engine, a pair of rear wheels, and a moving clutch between the engine and the rear wheels. The clutch includes a shell filled with lubricating oil, a driving component with a concave part and a driven component with a convex part. The driving and driven components are immersed in lubricating oil. The clutch has a characteristic curve shown in a coordinate system, the vertical axis of the system shows the coefficient of friction between the concave and convex parts, and the horizontal axis of the system shows a parameter, which is calculated by the ratio of the convex part to the concave part The product of revolutions per second and oil viscosity is divided by the surface pressure between the concave and convex parts. The characteristic curve includes first and second straight lines. The first and second straight lines meet each other at an inflection point. This point of inflection corresponds to a switching point when the working machine switches from a high-load driving state to a low-load driving state or vice versa. The recess may have a spiral groove and a plurality of straight grooves formed on its surface. The straight grooves extend perpendicular to the helical grooves.

Description

technical field [0001] The invention relates to an improvement of a walking working machine, which includes a driving wheel and a driving source for driving the driving wheel. Background technique [0002] Known walk-behind working machines include walk-behind lawnmowers. Figure 23 herein depicts an example of such a walk-behind lawn mower in side elevation. A walking lawn mower 200 for mowing grass 201 includes an engine 202 , a clutch 208 for transmitting driving force from the engine 202 to rear wheels 209 , and blades 203 rotated by power from the engine 202 . The lawn mower 200 also includes a handle 205 , a handle 206 connected to the handle 205 and a clutch lever 207 mounted on the handle 205 . The front wheels of lawn mower 200 are referenced 210 . In the case of mowing grass 201 with a lawn mower 200 , an operator 204 first starts the engine 202 thereby rotating the blade 203 . Then the operator 204 rotates the clutch lever 207 forward while holding the handle 2...
