Embodiment Construction

[0049] Such as Figure 1 to Figure 4 As shown, a hand-propelled self-propelled traveling machine 100 includes: a chassis 10 , a handle 20 , wheels 30 , a motor 40 and a transmission mechanism 50 . The hand-propelled self-propelled traveling machine 100 can also be called a power tool.

[0050] The chassis 10 is used to mount the motor 40 . Wheels 30 are used to support the chassis 10 . The wheels 30 touch the ground, and the wheels 30 can rotate around the first axis 102 relative to the chassis 10, so that the hand-propelled self-propelled traveling machine 100 moves relative to the ground. The handle 20 is connected to the chassis 10, and the user can push the handle 20 to move the chassis 10 relative to the ground, so that the hand-propelled self-propelled traveling machine 100 moves relative to the ground. The handle 20 is operated and manipulated by a user to control the push-pull self-propelled traveling machine 100 .

Abstract

A hand-propelled self-propelled traveling machine (100), comprising: a clutch (50a) for realizing transmission between a wheel (30) and a drive shaft (51); the clutch has a driving state that the drive shaft drives the wheel to rotate and the wheel is relatively The unlocked state of the transmission shaft rotation; the clutch includes: the driving part (57), coupled to the transmission shaft; the driving part and the transmission shaft rotate synchronously; The clutch moves between the unlocked positions in the unlocked state; the transmission member (56) is connected to the wheel; the transmission member drives the wheel to rotate; the movable friction member (53) forms a limiting groove (531); the movable pin part is located in the limiting groove The movable pin and the movable friction piece rotate synchronously; the fixed friction piece (55) is fixed to the chassis (10) or is used as a part of the chassis; the fixed friction piece and the movable friction piece are in frictional contact. The clutch of the hand-push self-propelled traveling machine has high reliability.

Description

technical field [0001] The present disclosure relates to a hand-propelled self-propelled traveling machine. Background technique [0002] Lawn mowers, snowplows, etc. are common hand-propelled self-propelled machines. The hand-propelled self-propelled traveling machine includes a motor, wheels and a transmission mechanism. The motor drives the wheels to rotate through the transmission mechanism, so that the hand-propelled self-propelled traveling machine moves relative to the ground. [0003] When the hand-propelled self-propelled traveling machine turns, the wheels on the left and right sides need to rotate at different speeds. The traditional hand-push self-propelled traveling machine is provided with a clutch so that the left and right wheels can rotate asynchronously. Optionally, the rotation speed of one side wheel can be greater than that of the other side wheel. A clutch that performs this function is also called a differential. This traditional hand-propelled sel...
