Abstract

The invention discloses a clutch transmission device of a self-propelled mower. The clutch transmission device comprises a shell assembly, a shaft lever, a worm wheel assembly, a worm, a sliding sleeve, a swing link, a rocker arm, a return spring and a clutch stay wire. Compared with the prior art, the clutch transmission device has the advantages that: a cutter and a motor of the mower drive a transmission assembly to run, the transmission assembly drives the worm and the worm wheel assembly to run, and engagement and disengagement of the transmission assembly and a mower wheel set are realized between the worm and the shaft lever by means of fit of balls and ball holes; the device has small structure and size, parts are simple and easily made, and components of a transmission lock such as keys, pins and the like are not needed; and the device is novel and reliable in structure, power-saving in operation, low in friction loss, low in clutch noise and thorough in separation, and does not slip.

Description

technical field [0001] The invention relates to a lawn mower, in particular to a clutch device of a lawn mower and clutch devices of other machines. Background technique [0002] Lawn mowers in the prior art usually use manpower to push the wheels of the lawn mower forward, while the lawn mower uses a motor to drive the cutter to rotate at high speed, cut off the grass with the cutter, and cut off the grass along the direction of rotation of the cutter. Grass removal machine. This lawnmower can achieve the purpose of quickly trimming the grass, but the user must apply force to push the lawnmower, and the physical load is still relatively heavy for large-area mowing work. [0003] For this reason, when existing some lawnmowers that walk automatically, add drive motor to wheel tool in addition, to drive the lawnmower to walk automatically, but, obviously opinion is, this can increase the cost of lawnmower greatly. [0004] Therefore, someone thinks of driving the lawn mower ...
