Detailed description of the invention
Be described in detail below in conjunction with accompanying drawing 1 pair of embodiment of the present invention hybrid transmissions.
Should be clear and definite, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
Embodiment 1: described hybrid transmissions comprises: the bent axle 11 of driving engine 1, single planet circular system, gearshift and motor;
Bent axle 11 is connected with the gear ring (not shown) of described single planet circular system by flywheel 12;
The pinion carrier 32 of described single planet circular system connects the input shaft 10 of described gearshift, and the output shaft 20 of described gearshift connects the rotor shaft 30 of described motor;
Sun wheel 31 is connected with the one-way lock mechanism being controlled by whole-control system, and is provided with power-transfer clutch 6 between sun wheel 31 and described gear ring.
The hybrid transmissions that the embodiment of the present invention provides, when the engine is not in operation, described gearshift is in Neutral Position, and power drives the output shaft rotation of described gearshift and then driving vehicle to travel by described motor through described rotor shaft; When engine starting is worked, first whole-control system controls described gearshift and transforms to certain gear by neutral gear and control described one-way lock mechanism simultaneously and made it to rotate backward by described sun wheel locking, the power of driving engine is inputted by described gear ring, the input shaft of described gearshift is outputted to through described pinion carrier, be delivered to described output shaft by described gearshift acceleration or deceleration again, transmitting ratio is now the product of the transmitting ratio of gearshift under the transmitting ratio of described single planet circular system and this gear; If now under this gear, whole-control system controls the combination of described power-transfer clutch, then described sun wheel and described gear ring are just combined in aggregatesly rotates forward simultaneously, the transmitting ratio of described single planet circular system is 1, now the transmitting ratio of whole driving device be gearshift under this gear transmitting ratio, be equivalent to achieve two different transmitting ratios like this under a gear, for multi-speed gear box, the numbers of gear steps of gearshift is decreased half by this device, because this reducing the axial dimension of this hybrid transmissions, simplify the structure.
For above-described embodiment, it should be noted that, output shaft 20 is connected with main reduction gear, travels to drive vehicle; Sun wheel why is selected to connect the locking of the sun wheel that one-way lock mechanism realizes in addition, be because the torque of sun wheel is the 1/K (K is the ratio of the number of teeth of gear ring and the number of teeth of sun wheel) of the torque of gear ring, the capacity of described one-way lock mechanism can be reduced like this thus reduce the size of described one-way lock mechanism and then simplify the structure of hybrid transmissions.
Secondly, sun wheel 31 is provided with sun wheel center shaft 33, sun wheel center shaft 33 can be hollow shaft, pinion carrier 32 is provided with pinion carrier center shaft 34, pinion carrier center shaft 34 passes described hollow shaft and is connected with the input shaft 10 of described gearshift, adopts bearings between sun wheel center shaft 33 and pinion carrier center shaft 34.Such sun wheel center shaft 33 and pinion carrier center shaft 34 coaxial line, and the two can be arranged in the same side of described single planet circular system, make power transmission more steady, and structure is simple, saves installing space.
Again, described one-way lock mechanism can also comprise free-wheel clutch 5 and drg 4, and the inner ring of free-wheel clutch 5 is connected with sun wheel center shaft 33, outer shroud is connected with drg 4.Like this, when after engine ignition, described gearshift is placed in Neutral Position, described gear ring and flywheel 12 rotate under the drive of the bent axle 11 of driving engine, now drg 4 is in release position, then free-wheel clutch 5 is in released state, and sun wheel 31 can oppositely freely be rotated, and now described single planet circular system does not have Power output; When described gearshift hangs up certain gear, drg 4 starts braking under the control of whole-control system, and sun wheel 31 braked by free-wheel clutch 5, then the power of driving engine is inputted by described gear ring, export through pinion carrier 32, and travelled by described gearshift and then driving vehicle.When vehicle travels under this gear, if whole-control system control clutch 6 combines, then described gear ring and sun wheel 31 are combined into one and rotate forward simultaneously, drg 4 discharges under the control of whole-control system, or under the effect of free-wheel clutch 5, drg 4 also can not discharge, and does not affect transmission effect.
Further, described gear ring is embedded in flywheel 12.Like this, the power of driving engine is input to described single planet circular system by flywheel 12 by described gear ring and outputs to described gearshift by pinion carrier 32.Wherein, the outer ring of described gear ring can directly be embedded in described flywheel, and without the need to drawing gear ring center axle in addition, simplifies the structure of hybrid transmissions.And if described single planet circular system selects power to be exported by gear ring, just need to draw gear ring center axle.
Further, flywheel 12 internal fixtion is connected with torsional vibration damper (not shown).This is because driving engine is from producing larger vibration in the process of output torque, also larger percussion vibration can be produced in addition in power transmission process, this has considerable influence to the sound quality of car load and the stability of transmission of power, therefore the embodiment of the present invention in the flywheel played a crucial role integrated torsional shock absorber to reduce the vibration of car load.Wherein torsional vibration damper can be integrated in described flywheel, also can be arranged in described flywheel as independent parts.
