Wherein: 1. wheel hub, 2. centre wheel, 3. planetary gear, 4. ring gear, 5. centre pinion, 6 ratchets, 7. ratchet ring, 8. end cap, 9. sealing ring, 10. left shaft, 11. the air pressure adjustment hole, 11-1. regulates through hole, the contraction-like outlet of 11-2. taper, and 11-3. necking down hole, the hole is amplified in the 11-4. taper.
Embodiment
As Fig. 1, a kind of motor of electric motor car shown in 2, comprise wheel hub 1 and be arranged on the direct current machine in the wheel hub 1 and be arranged on planetary reducer in the wheel hub 1, planetary reducer comprises centre wheel 2, planetary gear 3 and ring gear 4, centre wheel 2 and planetary gear 3 engagements, planetary gear 3 and ring gear 4 engagements, centre wheel 2 is arranged on the centre pinion 5 of direct current machine, have the pawl type clutch structure between the ring gear 4 of described planetary reducer and the relative wheel hub that moves in a circle 1, the pawl type clutch structure is that the outside of ring gear 4 has ratchet 6, the inner ring of wheel hub 1 has the ratchet ring 7 that matches with ratchet 6.
As shown in Figure 1, wheel hub 1 two ends are provided with end cap 8, be provided with sealing ring 9 between wheel hub 1 and the end cap 8, be filled with the liquid lubricating oil of Castor Oil planetary reducer and clutch structure in the cavity that wheel hub 1 and end cap 8 and sealing ring 9 constitute, and end cap 8 is provided with the pasta observation window planetary reducer is worked under the state of liquid oil lubrication, both reduced noise, reduce mechanical wear again, prolonged useful life greatly, and observed, be convenient for changing lubricating oil by the pasta observation window.
As shown in Figure 3, two end cap 8 passes a shaft respectively, be positioned at the left shaft 10 that is of centre pinion 5 left ends, shaft 10 centers, a left side are axially arranged with air pressure adjustment hole 11, be filled with fiber filling agent in the air pressure adjustment hole 11, air pressure adjustment hole 11 is variform syllogic air pressure adjustment hole 11, first section for regulating through hole 11-1, regulating through hole 11-1 left end is the contraction-like outlet of taper 11-2, the contraction-like outlet of taper 11-2 connects second section necking down hole 11-3, and second section necking down hole 11-3 connects the 3rd section taper amplification hole 11-4.Owing to self can produce heat, make air pressure inside during the direct current machine running, once exhaust process greater than external pressure, be in the progressively state of cooling when shutting down, air pressure inside can be less than external pressure, and once breathing process reaches air pressure balance by the suction and discharge process.Because motor of electric motor car can not be accomplished hermetically sealed, internal lubrication oil can outwards overflow along the slit, therefore on left shaft 10, establish air pressure adjustment hole 11, fiberfill fibers filler in air pressure adjustment hole 11, have only a small amount of gas to enter like this, and oil and water can not pass through, and make the air pressure natural equilibrium of motor of electric motor car under different situations thereby reached, and prevent the purpose of leakage of oil.
