Surface contact, meanwhile, activity cone block outer wall and outer connector second cone segment table face contact, for convenient for narration, by interior connection
Body, activity cone block and splined shaft are formed by structural body and are denoted as drive block, when the torque between drive block and outer connector is less than
When certain numerical value, static friction state is between drive block and outer connector, drive block and outer connection physical efficiency are in stiction
Effect is lower to be rotated synchronously, after the torque between drive block and outer connector is greater than certain numerical value, drive block and outer connector
Relative motion state will be converted to dynamic friction state by static friction state, and drive block and outer connector can relatively rotate,
After the torque between drive block and outer connector is varied down to certain numerical value again, the relative motion shape of drive block and outer connector
State can be converted to static friction state again again；After the utility model, when vehicle smooth-ride, transmission shaft output
Torque can be transmitted on drive block by flange arrangement, and drive block synchronous under stiction effect can turn with outer connector
It is dynamic, vehicle movement is driven, when the resistance that driving wheel is subject to increases suddenly, the speed of service of drive axle internal drive structure also can
Suddenly decline, at this point, the torque between drive block and outer connector will dash forward since the output torque of transmission shaft does not change
So increase, so that drive block and outer connector overcome stiction and relatively rotate, this can be to avoid biggish
On component in moment loading to drive axle, so that the component to drive axle plays a protective role, when vehicle is replied steadily again
After driving status, drive block and outer connector can also be converted to static friction state again；When it is implemented, can be by adjusting first
Adjusting nut and second adjustment nut control the compression degree (namely regulating friction force square) of two friction parts, so that making can
Permanent Torque couplings are adjusted only to transmit calibration torque.
