It is effectively protected the even running of motor and working machine, and its manufacture craft is simple, manufacturing cost is cheap.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of specific embodiment of the present invention；
Fig. 2 is centrifugal valve structural schematic diagram in specific embodiment of the present invention.
Specific embodiment
Below in conjunction with Detailed description of the invention specific embodiment of the present utility model.It is as shown in Figure 1 and Figure 2: including supporting box
1, scoop tube 3 is fixedly installed by scoop tube connection component 2 on the supporting box 1, rotational support has defeated in supporting box 1
Enter axle sleeve 4, the input axle sleeve 4 is connected with the first pump impeller 5, and first pump impeller 5 passes through intermediate ring 6 and the second pump impeller 7
It is connected, is supported by output shaft 8 in 1 inner bearing of supporting box, the output shaft 8 is symmetrical arranged by support sleeve 9 and two
Turbine 10 connect, and two turbines 10 match with the first pump impeller 5 and the second pump impeller 7 respectively, in the first pump impeller 5
End is additionally provided with outer housing 11, and the scoop tube 3 is located at outer housing 11 and is formed by inner cavity, passes through spiral shell on intermediate ring 6
Line connection type is equipped with centrifugal valve 12, and centrifugal valve 12 includes valve body 13, and valve body 13 is by oil outlet 15, channel 19, valve ball room 20
All around 4 flow-in holes 16 form, and 4 flow-in holes 16 are arranged in valve ball room 20 at channel 19, and 19 diameter of channel is big
In 15 diameter of oil outlet, spring 14 is set in the channel 19,14 diameter of spring is greater than 15 diameter of oil outlet, valve ball room 20
Diameter is greater than channel 19, and valve ball 17 is arranged in the valve ball room 20, and 17 diameter of valve ball is greater than 19 diameter of channel, and spring 14 begins
Valve ball 17 is pushed out eventually, and valve ball 17 is blocked by the retaining ring 18 that 13 opening of valve body is arranged in.
The course of work is as follows:
By the output axis connection of the input axle sleeve 4 of the present embodiment and driving motor, i.e., it is able to drive when driving motor works
Input axle sleeve 4 rotates, and input axle sleeve 4 will drive the first pump impeller 5 being attached thereto, intermediate ring 6 and the second pump impeller 7 and rotate together,
Since the setting to match with the first pump impeller 5 and the second pump impeller 7 is there are two turbine 10, the medium in 1 inner cavity of supporting box
Under effect, two turbines 10 are also started turning, final that output shaft 8 is driven to rotate, and realize the output of torque；
Since valve control filling liquid fluid-flywheel clutch realizes the transmitting of torque, meeting using two sets of pump impellers, turbine structures jointly
Intermediate ring 6 can be set between two sets of working chambers, and intermediate ring 6 has biggish spatial transition close to outer rim, be suitble to setting from
Heart valve 12.
When coupling device off working state, centrifugal valve 12 is in an open state (such as Fig. 2).When the motor is energized, in centrifugal valve 12
The valve ball 17 of configuration will receive the effect of itself centrifugal force and a small amount of working solution centrifugal pressure, and gradually reduce spring 14, in valve ball
Channel 19 is moved closer in room 20, centrifugal valve 12 is still in an open state at this time, and working solution enters flow-in hole 16 and passes through valve ball room
20 and channel 19 reach oil outlet 15 and be ejected into supporting box 1, reduce filling amount and delayed starting time of fluid-flywheel clutch,
Achieve the purpose that smooth starting；With the increase of filling amount, working solution centrifugal pressure becomes larger, in hydraulic coupler rotor state
For pressure maximum, centrifugal pressure is greater than the elastic force of spring 14 at this time, and valve ball 17 is pushed to channel 19 and influent stream in valve ball room 20
Between hole 16, the working solution discharge in working chamber is blocked, centrifugal valve 12 is in off state, and valve ball 17 has blocked 19 lower end of channel
Mouthful, fluid-flywheel clutch normal work is not influenced.Likewise, when fluid-flywheel clutch shut down or overload when, working solution can reduce or
Person's disorder is unable to reach maximum centrifugal pressure, and centrifugal valve 12 is greater than centrifugal pressure by 14 elastic force of spring at this time, is pushed away by spring 14
Between channel 19 and flow-in hole 16, centrifugal valve 12 is in an open state, and working solution reenters flow-in hole 16 and passes through 20 He of valve ball room
Channel 19 reaches oil outlet 15 and is ejected into supporting box 1, increases working solution discharge rate, reaches overload protection and fast clutch
Purpose.
Therefore this centrifugal valve 12 is applied on valve control filling liquid fluid-flywheel clutch, effectively optimizes common valve control filling liquid
Fluid-flywheel clutch realizes the purpose of smooth starting, overload protection and fast clutch on its basis.
