Specific embodiment
The principles of the present invention and feature are described below, example is served only for explaining the utility model, and
It is non-to be used to limit the scope of the utility model.
As shown in figs. 1 and 3, a kind of electric-controlled silicon oil clutch, including shell 1, front cover 2, the driving shaft being inserted in shell 1
3 and the active plate 4 on driving shaft 3, front cover 2 and the sealed connection of shell 1 form inner space, equipped with oil storage in inner space
Chamber 5, active plate 4 engage to form working chamber 6 with shell 1 and front cover 2, is equipped between working chamber 6 and shoe cream room 5 and flows for silicone oil
Oil returning tube 56 is equipped with the valve block 7 of silicone oil circulation between a control working chamber 6 and shoe cream room 5 between working chamber 6 and shoe cream room 5,
Valve block 7 is under the state of not stressing, because own resilient opens the oil outlet 10 that shoe cream room 5 leads to working chamber 6, at this time in shoe cream room 5
Silicone oil can be entered in working chamber 6 by oil outlet 10, the high-speed rotation under the drive of driving shaft 3 of active plate 4, active plate 4 is high
By the silicone oil in working chamber 6 when speed rotation, since silicon oil viscosity is big, can play the role of transmitting torque, so that front cover 2 is in master
Under the drive of movable plate 4 also can high-speed rotation, and front cover 2 is connect with fan, and fan high-speed rotation plays the effect of heat dissipation.Active plate
4 side wall is oil-scraper face, and front cover inner sidewall is equipped with oil return hole 21, and oil return hole 21 is communicated with oil returning tube 56, at oil return hole 21
Equipped with gear oil clot 8, gear oil clot 8 is mounted on front cover inner sidewall.
As shown in Fig. 2, gear oil clot mounting base 81 is equipped on front cover inner sidewall at oil return hole 21, the gear insertion gear oil of oil clot 8
In block mounting base 81, the region on front cover inner sidewall in addition to keeping off oil clot mounting base 81 is equipped with pressure stabilizing tooth 22, i.e. pressure stabilizing tooth
22 is not set at gear oil clot mounting base 81.Oil return hole 21 be arranged in gear oil clot mounting base 81 between region, when silicone oil by
When centrifugal force acts on, silicone oil is concentrated between oil-scraper face and front cover inner sidewall, drives when under high speed rotation of the silicone oil in active plate 4
When to oil return hole 21, due to keeping off the presence of oil clot 8, so that the pressure increase at oil return hole 21, so that silicone oil be accelerated to enter oil return
Hole 21 flows to shoe cream room 5 through oil returning tube 56.The silicone oil for receiving centrifugal force effect can be full of between pressure stabilizing tooth 22, pressure stabilizing tooth 22
The effect for reducing pressure oscillation can be played.
