The gear switching of power drive system is realized by clutch 140 and brake 150, and the gearshift executive component of power drive system carries out according to table one。
The gear of table one power drive system performs figure
Wherein, "○" represents that separation, "●" represent combination, Cl1Represent first clutch 140, Cl2Represent brake 150。
During one gear, drive motor 110 rotates forward (direction of motor rotation realizing car load advance is forward direction), impart power to first planet row's sun gear 131, power is passed to first planet seniority among brothers and sisters star-wheel 132 by first planet row's sun gear 131 further, now brake 150 works, second planet row planet carrier 137 and first planet row's ring gear 134 are braked, so that the first planet seniority among brothers and sisters star-wheel 132 engaged with first planet row's ring gear 134 carries out rotation and revolution, further power is transferred to first planet seniority among brothers and sisters carrier 133;Meanwhile, clutch 140 (normally opened) does not work, and clutch 140 disconnects with a support plate 141, and the second planet row ring gear 138 disconnects with the second planet row planet carrier 133 and output shaft 160 simultaneously, and namely the second planet row entirety does not work。Now, power is transmitted to output shaft 160 by first planet seniority among brothers and sisters carrier 133 by circular support dish 141, it is achieved the output of power。
During two gears, drive motor rotates forward, brake 150 does not work, itself and brake disks 151 disconnect, second planet row planet carrier 137 and first planet row's ring gear 134 can rotate, clutch 140 (normally opened) works, clutch 140 is connected with circular support dish 141, the first planet seniority among brothers and sisters carrier 133 that be connected fixing with circular support dish 141 is by power transmission to output shaft 160, it is further, second planet row ring gear 138 is combined with circular support dish 141, first planet row's ring gear 134 imparts power to the second planet row ring gear 138 by the second planet row planet carrier 137, so that power can be transferred to output shaft 160 by the second planet row ring gear 138, play the effect of speedup。
One gear rises two gear processes, realize clutch 140 (normally opened) by shift control unit and be switched to duty by off position, brake 150 is switched to off position by duty, the power of drive motor is delivered to first planet row's sun gear 131 by drive motor axle 123 end, rank star-wheel 132 then through first planet and be delivered to first planet seniority among brothers and sisters carrier 133, rank carrier 133 finally by first planet and be delivered to output shaft 160, and by the switching of clutch 140 (normally opened) and the duty of brake 150, realize the second planet row ring gear 138 and speedup power can be transferred to output shaft 160。
One gear process drops in two gears, realize clutch 140 (normally opened) by shift control unit and be switched to off position by duty, brake 150 is switched to duty by off position, the power of drive motor is delivered to first planet row's sun gear 131 by drive motor axle 123 end, rank star-wheel 132 then through first planet and be delivered to first planet seniority among brothers and sisters carrier 133, rank carrier 133 finally by first planet and be delivered to output shaft 160, and by the switching of clutch 140 (normally opened) and the duty of brake 150, realize the second planet row ring gear 138 and speedup power can not be transferred to output shaft 160。
When reversing gear, drive motor reversion (contrary with forward direction), reverse power is passed to first planet row's sun gear 131, power is passed to first planet seniority among brothers and sisters star-wheel 132 by first planet row's sun gear 131 further, now brake 150 works, second planet row planet carrier 137 and first planet row's ring gear 134 are braked, so that the first planet seniority among brothers and sisters star-wheel 132 engaged with first planet row's ring gear 134 carries out rotation and revolution, further power is transferred to first planet seniority among brothers and sisters carrier 133;Meanwhile, clutch 140 (normally opened) does not work, and clutch 140 and circular support dish 141 disconnect, and the second planet row ring gear 138 disconnects with the second planet row planet carrier 133 and output shaft 160 simultaneously, and namely the second planet row entirety does not work。Now, power is transmitted to output shaft 160 by first planet seniority among brothers and sisters carrier 133 by circular support dish 141, it is achieved traveling swung to by car load。
During neutral, clutch 140 (normally opened) and brake 150 all keep off position so that drive motor axle 123 and output shaft 160 are in released state, have cut off the transmission of power。
When car load need to be braked with a gear traveling, drive motor is switched to generator mode by electric motor mode, and drive system plays dragging effect, and the traveling kinetic energy of car load is converted to electric energy。
When car load need to be braked with two gear travelings, drive motor is switched to generator mode by electric motor mode, and clutch 140 (normally opened) does not work, and brake 150 works, and drive system plays dragging effect, improves Brake energy recovery efficiency。
As it has been described above, this utility model has the advantages that 1, power drive system by drive motor, a set of dual planetary gear planet row and clutch assembly composition, number of parts is less, compact conformation, it is simple to install, and in transmission process, meshed gears number is less, is effectively improved transmission efficiency。2, permanent-magnet synchronous driving motor and two shift transmissions are adopted to become one, reduce and raw-material make consumption, effectively reduce the cost of power drive system, also reduce the performance requirement to motor, decrease the complexity of control system, improve motor operational efficiency, add the continual mileage of electric motor car。3, drive motor can realize reversion, so realizing reversing gear by motor reversal, eliminates the gear shifting actuating mechanism reversed gear, and structure is compacter, and control of reversing gear is simple, easily realizes。4, there are motor and two kinds of mode of operations of electromotor in drive motor, and when car load is in damped condition, drive motor is converted to generator mode, plays Brake energy recovery, improves the utilization rate of car load energy, reaches to save the effect of the energy。
Although embodiment of the present utility model is disclosed as above, but it is not restricted in description and embodiment listed utilization。It can be applied to various applicable field of the present utility model completely。For those skilled in the art, it is easily achieved other amendment。Therefore, under the general concept limited without departing substantially from claim and equivalency range, this utility model is not limited to specific details and shown here as the legend with description。
