Between the first power source output shaft 12 and combined type planetary mechanism 11, be further provided with power source clutch mechanism 121, the second power source output shafts 13 and directly or for example, by suitable driving mechanism (driving gear set) connect compound planetary mechanism 11.Power source clutch mechanism 121, for the first power source output shaft 12 is controlled, specifically exports the power selectivity of the first power source output shaft 12 outputs to combined type planetary mechanism 11.
Power source clutch mechanism 121 can adopt traditional wet type or dry type clutch mechanism.For example, power source clutch mechanism 121 comprises driving link 1211 and driven member 1212, and when driving link 1211 and driven member 1212 joint, the power of the first power source output shaft 12 outputs exports combined type planetary mechanism 11 to.When driving link 1211 and driven member 1212 are when separated from one another, the power of the first power source output shaft 12 outputs does not export combined type planetary mechanism 11 to.Power source clutch mechanism 121 also can be replaced by one-way clutch mechanism.When the rotating speed of the element being connected with the first power source output shaft 12 of combined type planetary mechanism 11 is greater than the rotating speed of power source, one-way clutch mechanism, in surmounting state, is avoided the backflow of power.Can certainly between the second power source output shaft 13Yu compound planetary mechanism 11, suitable power source clutch mechanism be set.
In the present embodiment, combined type planetary mechanism 11 shares mode by single planetary row and double planet wheel rows of mixing by element and is composited, and specifically comprises the first sun gear 115, the second sun gear 116, the first row star-wheel 112, the second planet wheel 114, gear ring 111 and planet carrier 113.Wherein, the first row star-wheel 112 and the second planet wheel 114 common planet carrier 113.The first row star-wheel 112 and the first sun gear 115 outer gearings, gear ring 111 and the interior engagement of the first row star-wheel 112.The first sun gear 115, the first row star-wheel 112, gear ring 111 and planet carrier 113 form a single planetary row.The second planet wheel 114 between the second sun gear 116 and the first row star-wheel 112, and respectively with the second sun gear 116 and 112 outer gearings of the first row star-wheel.The second sun gear 116, the first row star-wheel 112, the second planet wheel 114, gear ring 111 and planet carrier 113 further form a double planet wheel rows of mixing.
In the present embodiment, control mechanism comprises arrestment mechanism 144 and output clutch mechanism 146.144 pairs of the first sun gears 115 of arrestment mechanism are controlled, specifically the first sun gear 115 is carried out to selectivity braking, output clutch mechanism 146, for the second sun gear 116 is controlled, is specifically engaged to the second sun gear 116 selectivity the second fixed shaft type gear teeth wheels input shaft 19.The second sun gear 116 further connects the first power source output shaft 12 and the second power source output shaft 13, and gear ring 111 connects the first fixed shaft type gear teeth wheels input shaft 18.
In the present embodiment, arrestment mechanism 144 comprises brake calipers 1441 and brake disc 1442.Brake disc 1442 is coaxially fixed on the first sun gear 115, and brake calipers 1441 is for brake disc 1442 is carried out to selectivity braking, thereby the first sun gear 115 is carried out to selectivity braking.Arrestment mechanism 144 can be wet-type multi-disc arrestment mechanism or other suitable arrestment mechanisms.Output clutch mechanism 146 comprises driving link 1461 and the driven member 1462 being separately positioned on the second sun gear 116 and the second fixed shaft type gear teeth wheels input shaft 19, when the output driving link 1461 of clutch mechanism 146 and driven member 1462 engage, output clutch mechanism 146 drives its two parts controlling synchronously to rotate.
In the present embodiment, when motor (the first power source) operation and motor (the second power source) while closing, above-mentioned clutch is equivalent to a common automatic clutch.When arrestment mechanism 144 with output clutch mechanism 146 all in separated state, the first power source output shaft 12 drives the second sun gears 116 to rotate.Now, because the second planet wheel 114, planet carrier 113, the first row star-wheel 112 and the first sun gear 115 are all in free state, cannot transmit power to the first and second fixed shaft type gear teeth wheels input shaft 18,19 of the first power source output shaft 12 outputs, be " separation " state of the clutch of common vehicle.When arrestment mechanism 144 is in braking state, output clutch mechanism 146 is when separated state, and the first sun gear 115 is braked mechanism's 144 brakings and locked.Now, the power of the first power source output shaft 12 outputs is passed to the first fixed shaft type gear teeth wheels input shaft 18 through the second sun gear 116, the second planet wheel 114, the first row star-wheel 112 and gear ring 111 with First Speed ratio.When output clutch mechanism 146 is in jointing state, be that driving link 1461 and driven member 1462 are bonded with each other and locked each other, arrestment mechanism 144 is when separated state, the power of the first power source output shaft 12 outputs is directly passed to the second fixed shaft type gear teeth wheels input shaft 19 by the second sun gear 116 and output clutch mechanism 146, thereby makes the power of the first power source output shaft 12 outputs be passed to the second fixed shaft type gear teeth wheels input shaft 19 with second speed ratio.Above-mentioned two states is equivalent to " joint " state of the clutch of common vehicle.
When motor (the first power source) cuts out, during motor (the second power source) operation, motor (the second power source) provides power through the second power source output shaft 13 to combined type planetary mechanism 11, drives the second sun gear 116 to rotate.Now, by describing similar mode above, control arrestment mechanism 144 and clutch mechanism 146, make the power of the second power source output shaft 13 outputs be delivered to any one in the first fixed shaft type gear teeth wheels input shaft 18 and the second fixed shaft type gear teeth wheels input shaft 19 through combined type planetary mechanism 11 selectivity, form pure motorized motions.
When motor (the first power source) and motor (the second power source) all provide power to combined type planetary mechanism 11, form mixed running pattern in parallel.When the anxious acceleration of needs maybe will overcome larger running resistance, motor (the first power source) work, power source clutch mechanism 121 engages, with the power that transmits motor to combined type planetary mechanism 11, motor also provides power to combined type planetary mechanism 11 simultaneously, so that vehicle obtains larger acceleration or driving force.
Vehicle high-speed is in service, and the efficiency of motor (the first power source) is relatively high, can be completely by motor-powered vehicle.Now, motor cuts out, and is equivalent to a rotary inertia or a load.For example, when providing battery (not shown) energy storage of energy inadequate for motor, or during vehicle high-speed operation, under some operating mode, motor has power more than needed, and it is battery charging that motor can be used as generator, and now motor is equivalent to a load.Further, when vehicle needs retarding braking, motor can change generator into, as fixed shaft type gear teeth wheels at the anti-energy that drags recovery vehicle of gear, be battery charging.
