Embodiment
For ease of better understanding the present invention, combine accompanying drawing that the preferred embodiments of the present invention are specified as follows at present:
Please with reference to Fig. 1, Fig. 1 is a structural representation of the present invention.Fourth gear automatic transmission of the present invention comprises: first input shaft 14, and it is driven by first motor 1, and which is provided with one grade of actuation gear 6 and third gear actuation gear 7; Second input shaft 13, it is driven by second motor 2, and which is provided with second gear actuation gear 8 and fourth gear actuation gear 9; Output shaft 15; Which is provided with first synchronizer 3 and second synchronizer 4; And with one grade to one grade of fourth gear actuation gear engagement, second gear, third gear, fourth gear driven gear; The wherein engagement of the said one grade of actuation gear 6 of first synchronizer, 3 controls and first speed driven gear and third gear actuation gear 7 and third gear driven gear, the engagement of the said second gear actuation gear 8 of second synchronizer, 4 controls and second gear driven gear and fourth gear actuation gear 9 and fourth gear driven gear; And control mechanism, among the present invention gearbox controller 16, be connected with second synchronizer 4 with said first motor 1, second motor 2, first synchronizer 3 respectively, be used to control speed changer with different gear outputting powers.Wherein, said first input shaft 14 and the 13 coaxial sockets of said second input shaft.
The operating mode introduction of fourth gear automatic transmission of the present invention is following:
Starting: this invention can realize three kinds rise step modes 1. gearbox controller 16 one grade of actuation gear 6 of sending first speed driven gear and said first input shaft 14 on the said output shaft 15 of command control said first synchronizer 3 operations mesh; Gearbox controller 16 sends instruction then; Making said first motor 1 drive said first input shaft 14 rotates; And then drive said output shaft 15 to realize one grade of starting; This be under the normal condition starting 2. the gearbox controller 16 second gear actuation gear 8 that sends second gear driven gear and said second input shaft 13 on the said output shaft 15 of said second synchronizer 4 operation of command control mesh; Gearbox controller 16 sends instruction then, makes said second motor 2 drive said second input shaft 13 and rotates, and then drive said output shaft 15 to realize the second gear starting; This is the step mode that rises under the relatively more sliding situation in a kind of road surface; 3. under special starting situation (uphill starting), gearbox controller 16 sends said first speed driven gears of command control first synchronizer, 3 operations and 6 engagements of one grade of actuation gear like snowfield starting, and second synchronizer, 4 said second gear driven gears of operation and said second gear actuation gear 8 mesh; Said first motor 1 drives one grade of actuation gear, 6, the second motor 2 and drives second gear actuation gears 8, superposes and starts to walk with powered vehicle thereby drive input torque that output shaft 15 makes two motor simultaneously.
Cruise: behind vehicle start, according to different gears, two motors can alternation.After one grade of starting, if satisfy the condition of second gear in advance.Gearbox controller 16 sends instruction, and one grade of action that rises second gear is accomplished in second synchronizer, 4 said second gear driven gears of operation and 8 engagements of said second gear actuation gear then; After action is accomplished; According to schedule, first motor 1 cuts out power output gradually according to curve shown in Figure 2 under the control of gearbox controller 16, and second motor 2 increases power output gradually according to curve shown in Figure 2; Final first motor 1 cuts out, 2 work of second motor.Reversed in order when second gear falls one grade, second motor 2 reduces moment of torsion output, final plant closure, first motor, 1 output torque increases gradually, increases curve according to the moment of torsion among Fig. 2.Finally realize fully by first motor, 1 powered vehicle.Other gearshift action is similar.
Anxious acceleration, climbing or road conditions bad working environments; This moment, the driver demand torque was bigger, and the driving mode that adopts in the cruising condition can not satisfy the moment of torsion needs fully, if current according to current gear be one grade; Then work together with second gear for one grade; If current is second gear, then second gear and one grade are worked together, if current for third gear one grade work together with third gear.Two motor driven in common vehicle driving, thus satisfy torque demand.
The present invention does not establish reverse gear, and reverse gear realizes through the counter-rotating of motor.
Fault mode: one in the two motors is broken down and is not influenced going of vehicle, and after first motor, 1 fault, vehicle can also go with second gear, and vehicle can also go with one grade after second motor, 2 faults.
Above-described; Be merely preferred embodiment of the present invention; Be not in order to limiting scope of the present invention, promptly every simple, equivalence of doing according to the claims and the description of application of the present invention changes and modifies, and all falls into the claim protection domain of patent of the present invention.
