According to the transmission assembly, a square thread clutching device, a frustum-shaped braking device, a planet wheel speed reduction device, a rack and a sector gear are used for outputting positive and negative torque; and the transmission assembly has a simple structure and long service life, is reliably driven and accurately braked, occupies a small space, is convenient to mount and maintain and is high in novelty and creativity.

Description

technical field [0001] The invention relates to a transmission mechanism of a washing machine, in particular to a transmission assembly of a stirring type washing machine. Background technique [0002] Similar to other washing machines, agitating washing machines have washing and dehydration conditions. Under washing conditions, the pulsator rotates forward and reverse to achieve the purpose of washing; under dehydration conditions, the pulsator rotates synchronously with the inner tub at high speed to achieve the purpose of dehydration. When washing, the forward and reverse rotation of the pulsator can better wash the clothes and prevent the clothes from being entangled, and the forward and reverse rotation of the pulsator is generally realized by the controller controlling the forward and reverse rotation of the driving motor. Frequent starting and forward and reverse rotation shorten the service life of the drive motor. [0003] In addition, due to the working requiremen...

Problems solved by technology

When washing, the positive and negative rotation of the pulsator can better wash the clothes and prevent the clothes from being entangled. The positive and negative rotation of the pulsator is generally realized by the controller controlling the positive and negative rotation of the drive motor. This transmission mode is due to the Frequent starting and forward and reverse rotation greatly shorten the service life of the drive motor

[0003] In addition, due to the working requirements of the washing machine, the transmission mechanism must complete the deceleration operation of the pulsator under the washing condition, and at the same time, the inner tub must remain stationary, while under the dehydration condition, the pulsator and the inner tub must rotate at high speed synchronously. Brake in time when necessary, so the structure is relatively complicated and requires the effective cooperation of the clutch mechanism and the brake mechanism. In the prior art, the clutch mechanism is generally composed of a ratchet, a pawl, and a lever for controlling the clutch of the pawl, and an additional The brake mechanism is relatively large in size and complicated in structure, and it is inconvenient to install and maintain. At the same time, because the brake mechanism is set up separately, it is easy to cause the problem of incoordination between brake and drive, and sometimes the brake and drive are performed simultaneously or the drive stops. The situation of braking after a period of time is not conducive to use
