Abstract

The invention relates to an integrated control mechanism for an automatic walking device clutch and a continuously variable transmission of a lawn mower, which comprises a variable speed pulling rod, a pulling cable, a pulling cable fixing plate, a stroke plate, a belt pulley, a belt, and a small bevel gear, a large bevel gear, a return torsional spring, a return tension spring, a shifting fork, a clutch, a driving shaft, a compression spring and the like which are arranged in a chamber consisting of a box body and a box cover. When the integrated control mechanism is controlled, the variable speed pulling cable drives the stroke plate to drive the shifting fork so as to push the clutch to axially move through counter pull of the pulling cable fixing plate; and the clutch is meshed with the large bevel gear by combining elastic force of the compression spring on the driving shaft so as to drive the driving shaft to rotate. When the pulling cable is loosened, the shifting fork drives the clutch to separate from the large bevel gear in a reverse direction. Meanwhile, the integrated control mechanism achieves variable speed through clenching degree of the belt pulley and the belt, achieves integrated control of one pulling cable and has the advantages of ingenious design and simple structure.

Description

technical field [0001] The invention relates to a clutch mechanism of a self-propelled mower or a control mechanism of a continuously variable transmission, in particular to an integrated control mechanism of a clutch of a self-propelled lawn mower and a continuously variable transmission. Background technique [0002] The self-propelled lawn mowers of the prior art either have a clutch mechanism or a continuously variable transmission mechanism, which are respectively controlled by drag cables. This is a technical solution familiar to the public. machine, such as the small self-propelled walking mower of 200710007178.9 disclosed in Chinese patent literature, which discloses the structure of the mower, and the working state of the mower is controlled by the hand-held operating mechanism and the clutch handle. The handle is for changing gears only. How to simultaneously control the lawn mower self-propelled clutch and continuously variable transmission through a cable to for...
