Abstract
The invention relates to a clutch device mechanism based on a cam shaft and a tappet structure. The mechanism achieves clutch separation and combination by means of a push rod and comprises a shell, a motor, a speed reducing assembly, the cam shaft and a tappet. The motor, the speed reducing assembly, the cam shaft and the tappet are arranged on the shell. The motor is connected with the cam shaft via the speed reducing assembly. The cam shaft and the tappet are connected in a rolling mode in order to drive the tappet to move back and forth. The tappet pushes the push rod to achieve clutch separation and combination.Compared with the prior art, the clutch device mechanism based on the cam shaft and the tappet structure is advantaged by being high in reliability and efficiency and excellent in sealing performance.

Described planetary reducer comprises planetary wheel carrier and is arranged on the planet wheel on planetary wheel carrier.
Described planetary reducer is one, two or third-level planetary gearing speed-reducer.
Described camshaft is provided with angular displacement sensor for monitoring cam axle angle and for the spacing position-limited shaft of high camshaft.Angular displacement of the cam is monitored by angular displacement sensor, realizes motor positive and inverse and stopping.
Described housing be provided with switch, for balance inside and outside atmospheric pressure breather plug, for checking the dipstick of lubricant oil oil mass and cutting the Magnetic bolt of precipitation for iron after device wearing and tearing.
The gap place of described housing is equipped with seal ring.
Described seal ring is O RunddichtringO, and the sealing of this O type circle prevents oil leak and water access mechanism.
Described push rod is connected with housing by extension spring.
Described push rod is connected with clutch arm by bearing pin.
Described motor adopts direct current generator, brush motor or brushless electric machine.
Working principle:
Motor of the present invention drives planetary reducer to rotate, planetary reducer driven gear group is rotated, thus drive cam axle, cam turns lift angle and increases gradually, adopt rolling friction between tappet and cam, thus drive tappet to move forward, tappet promotes push rod and realizes clutch separation, motor reversal driven gear group is rotated, and tappet moves backward thus realizes clutch and combines.
The angle that angular displacement sensor rotates to detect cam is equipped with in the present invention, forwards top radian rear motor power-off to, prevents motor rotation blockage.
Compared with prior art, the present invention has the following advantages:
1, reliability is high: adopt advanced automatically controlled cam production, and control accurately reliable, sensor detects cam rotational position, and cam has auto-lock function, prevents motor rotation blockage, and life of clutch is long.
2, efficiency is high: adopt planetary reducer and gear train gearing efficiency high.
3, good seal performance: housing adopts full-sealing device, and can prevent extraneous water and dust access mechanism, internal lubrication oil can not leak outside.
