Description

Single input three keeps off power assembly system
Technical field
The invention belongs to technical field of automobile transmission, are related to a kind of three gear power assembly systems of single input.
Background technology
The power assembly of electric vehicle mainly uses " single motor+single reduction gear " and " single motor+multi-change speed at present The technical solution of device ".
The power assembly of " single motor+single reduction gear " can only be by retarder come torque of slowing down, and the change of rotating speed is complete The full change for relying on motor speed.Therefore, it is desirable to the torque and rotating speed of the power assembly system of " single motor+single reduction gear " Range is very wide, to adapt to the various operating modes of vehicle traveling.Analogy：Vehicle is in starting and climbing, it is desirable that power assembly system is defeated The torque gone out is larger, and corresponding rotating speed is relatively low；Vehicle in straight good road surface when driving, it is desirable that power assembly system output Rotating speed is higher, and corresponding torque is smaller." single motor+single reduction gear " this style of power assembly is difficult to meet above-mentioned want It asks, often retarder uses large torque requirement of the big retarding than disclosure satisfy that starting climbing, but can not meet straight good Need small reduction ratio to obtain high-revolving requirement on good road surface when driving.More disadvantageously：In entire vehicle speed range, nothing Method makes power assembly always or the most of the time operates in efficient rotating speed and torque range, the utilization rate of electric energy compared with It is low, the course continuation mileage of electric vehicle can not be increased.
The shortcomings that overcoming above-mentioned " single motor+single reduction gear " needs total using the power of " motor+multiple-speed gear-box " At.Different gear ratio is selected so that power according to the different operating condition of vehicle by the speed changing function of multiple-speed gear-box Assembly system operates in full vehicle speed range in efficient rotating speed and torque region always, reduces energy loss, correspondingly increases Course continuation mileage is added.Although " single motor+multiple-speed gear-box " is compared with the shift quality of the power assembly of " bi-motor+multiple-speed gear-box " It is slightly worse；But " single motor+multiple-speed gear-box " axial dimension is small, light-weight, is conducive to arrange installation on vehicle, it is at low cost.
Existing single motor vehicle power assembly system, gear shift some is using the common cylinder tooth for fixing shaft type Wheel speed (i.e. manual shift transmission) and planetary transmission (AT automatic transmission).During manual gear shift of transmission Dynamic interruption, but it is simple in structure at low cost；Planetary gear automatic transmission shift quality is good, but complicated, of high cost, such as It is a kind of planetary gear type gearbox schematic diagram shown in Fig. 2, which is made of three planet rows, each planet row Including gear P1, planetary gear P2, gear ring P3 and planet carrier P4 (as shown in Figure 1), three planet rows are combined, and pass through three A clutch C1, C2, C3 and three brake bands B1, B2, B3 add the cooperation of one-way clutch F, can be by each planet Gear P1, gear ring P3 and the planet carrier P4 of row can be thus combined into more respectively as driving link, Passive part or fixing piece A gear.The associated component of the associated component and another planet row of one planet row of the type epicyclic transmission Interconnection, nesting, difficult arrangement extremely complex so as to cause entire power assembly system structure, to manufacture and repair band Carry out the processing method greatly difficult, especially the processing of gear ring can not use gear hobbing, therefore the efficiency processed is low, low precision, Cost is higher.
