Description

Technical Field

[0001] The utility model relates to the technical field of washing machine transmission, and particularly relates to a dual-power clutch and a washing machine. Background Art

[0002] The traditional washing machine reduction clutch mainly comprises a brake wheel shaft, a bearing, a brake wheel, a brake band, a reducer, a dehydration shaft, an input shaft, an output shaft and a clutch device. The dual-power reduction clutch is a new type of reduction clutch structure applied to a dual-power washing machine. Its main feature is that during washing, the inner barrel and the agitator of the washing machine rotate in opposite directions and at different speeds, so that the laundry is subjected to reverse turning forces from the inner barrel and the agitator during the washing process, playing a role of rubbing the laundry against each other, and having a higher washing cleanliness for the laundry.

[0003] The original dual-power reduction clutch uses a one-way bearing and a brake band to stop the brake wheel, so as to drive the agitator shaft and the dehydration shaft to rotate in opposite directions through a differential planetary gear train. However, if rapid direction switching is to be achieved, such as achieving stirring water flow, which requires short-term rotation, stop, reverse and other actions, the one-way bearing and the brake band will be damaged, which is not conducive to the service life of the clutch.

[0004] In view of this, the present application is specifically proposed. Content of the Utility Model

[0014] Further, the differential planetary gear train is arranged inside the brake wheel and includes an upper set of planetary gear trains and a lower set of planetary gear trains.

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0029] In the description of this specification, the descriptions with reference to terms such as "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples", etc. mean that the specific features, structures, materials, or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present utility model. In this specification, the schematic descriptions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0030] Such as Figures 1 to 3As shown, the utility model discloses a dual-power clutch, including a impeller shaft 1 and a dehydration shaft 2, wherein the impeller shaft 1 is concentrically sleeved inside the dehydration shaft 2, and the impeller shaft 1 and the dehydration shaft 2 are transmission-connected with an input shaft 15 through a differential planetary gear train 9, and a lower shaft sleeve 12 is arranged on the outer side of the input shaft 15, and the lower shaft sleeve 12 is connected with a brake wheel 8 as a whole, and a clutch sleeve 20 is sleeved on the outer side of the lower shaft sleeve 12, and the clutch sleeve 20 switches the upper and lower positions under the action of a shift fork device, so as to realize the meshing transmission of the clutch sleeve 20 and the input shaft 15 or to fix it relative to the mounting plate 4, and a brake belt 11 is connected to the brake wheel 8, and the brake belt 11 is installed on a brake lever 10, and the brake lever 10 controls the brake belt 11 to brake or release the brake wheel 8 under the action of an external force.

[0031] The dual-power clutch disclosed in the present application adopts a clutch sleeve 20 mounted on the lower sleeve 12, and the position of the clutch sleeve 20 is switched to realize the stopping or rotation of the brake wheel 8. The brake device formed by the brake rod 10 and the brake band 11, when the dual-power clutch is in the washing state, under the action of external force, the fork device drives the clutch sleeve 20 to move up, so that it is relatively fixed with the mounting plate 4, thereby limiting the rotation of the lower sleeve 12 and the brake wheel 8. At the same time, under the action of external force, the brake band 11 is in a braking state. When the input shaft 15 rotates, the lower sleeve 12 is fixed. According to the working principle of the differential planetary gear system, the inner ring gear and the upper planetary carrier rotate in the opposite direction with a reduced speed, respectively driving the dehydration shaft 2 and the impeller shaft 1 to rotate in the opposite direction, thereby realizing the dual-power washing mode. In particular, when the rotation direction is quickly switched, the bidirectional rotation of the impeller (agitation wheel) and the dehydration barrel can be well controlled to achieve A good washing effect can be achieved; when the dual-power clutch is in the washing and dehydration state, under the action of external force, the fork device drives the clutch sleeve 20 to move downward, so that it is meshed with the input shaft 15 for transmission, and the brake belt 11 releases the brake wheel 8. When the pulley or the motor rotor 22 rotates, it drives the input shaft 15, the lower sleeve 12, the brake wheel 8, etc. to rotate together. At this time, the planetary gears on the lower sleeve 12 and the input gears also rotate as a whole, thereby binding the entire differential planetary gear train 9 to rotate as a whole, driving the impeller shaft 1 and the dehydration shaft 2 to rotate as a whole, and realizing high-speed dehydration; when the dual-power clutch is in the dehydration state, due to an accident or human factor, the washing machine is suddenly powered off. At this time, the brake lever 10 is actuated, and the brake belt 11 brakes the brake wheel 8, so that the washing tub of the washing machine is decelerated from the high-speed rotation state, and the dual-power clutch is switched to the braking state.

[0032] The dual-power clutch described in the present application improves the clutch structure of the existing dual-power reducer. Through the combination of the fork device and the brake device, it realizes rapid response and reliable control of the engagement state of the dual-power reducer in different working conditions, ensures the safe operation of the washing machine, reduces the occurrence rate of failures, and reduces maintenance costs.

[0033] As a preferred example of the present application, the fork device includes a fork rod 17, a fork seat 18, and a fork rotating shaft 19.

At the same time, it ensures the fixation or rotation of the brake wheel in different states, ensuring the normal operation of the washing machine.

Lower teeth are provided at the lower end of the clutch sleeve 20, and the lower teeth mesh with the movable tooth 21 when the clutch sleeve 20 is in the lower position. This setting can realize the rapid switching between the washing state and the disengaged state of the washing machine through the spline connection between the lower shaft sleeve and the clutch sleeve and the design of the upper and lower teeth, and ensure the stability and reliability of the transmission system.

[0036] As a preferred example of the present application, a return compression spring 16 is provided between the clutch sleeve 20 and the fork seat 18. In the normal state, the return compression spring 16 presses the clutch sleeve 20 to the lower position to mesh with the movable tooth 21. This design enables the clutch sleeve 20 to move upward against the action of the return compression spring 16 during the washing state of the washing machine, thus ensuring the stability of the meshing of the clutch sleeve 20 and the clutch fixing tooth 23 relative to the mounting plate 4. After the washing is completed, the fork rod 17 returns to its original position, and the clutch sleeve 20 automatically returns to the lower position to mesh with the movable tooth 21 under the action of the return compression spring 16, simplifying the operation process, ensuring the stability and reliability of the transmission system in different working states of the washing machine, and thus improving the working efficiency and durability of the washing machine. As an example of the present application, the clutch sleeve 20 can also be in the upper position to mesh with the clutch fixing tooth 23 under the action of the return compression spring 16 or other torsion springs (provided at the fork rotating shaft) or hanging springs, so that the double-drive clutch described in the present application is in the washing working condition state during supply or in the normal state.

The fork lever 17 controls the clutch sleeve 20 to axially move up and down a certain distance on the lower shaft sleeve 12; the clutch fixed teeth 23 and the fork seat 18 are integrated and are integrally fixed on the bearing support 14 of the clutch.
