Abstract
The utility model discloses a uniaxial torque superposition hybrid power structure which comprises an engine, a clutch, a connecting mechanism and a drive motor. The engine is in power connection with the drive motor through the clutch and the connecting mechanism. The connecting mechanism comprises a shell, a transition bearing and a transition shaft. The transition shaft is penetratingly disposed in the shell. The middle of the transition shaft is nested into the transition bearing which is mounted on a bearing block in the middle of the shell. One end of the transition shaft extends into the clutch and is positioned by the guide bearing. The other end of the transition shaft is connected with one end of a motor shaft of the drive motor. Due to the fact that the connecting mechanism is added, the motor shaft is supported by two bearings, over-positioning of an original structure is eliminated, a spline shaft of the motor can be widened, and torque borne by the motor shaft can be increased without changing engine clutch spline shaft size. The uniaxial torque superposition hybrid power structure has the advantages of easiness to machine and good motor shaft stress condition.
Description
Technical field
The utility model relates to a kind of power plant, particularly relates to a kind of hybrid architecture of single shaft moment of torsion stack.
Background technology
The hybrid architecture of single shaft moment of torsion stack, be that wide structure is used in present hybrid power passenger car field, this is simple in structure, parts are few, but this structure engine directly links to each other with drive motor, long because of this motor axial dimension, requirements for quality is high, there is the problem of fatigue damage even off-axis in the drive motor axle.As shown in Figure 1, driving engine 1 ' directly passes to propulsion source the motor shaft 31 ' of drive motor 3 ' by power-transfer clutch 2 ', passes through transmission shaft 4 ' again and passes to wheel.Drive motor 3 ' belongs to direct transmission relatively.As shown in Figure 2, motor shaft 31 ' is supported by three bearings 51 ', 52 ', 53 ', has the location.Because the intensity of motor shaft 31 ' axle head 311 ' much larger than the intensity of spline place 312 ' shaft extension, so the flexural deformation phenomenon will appear in spline place 312 ' shaft extension, forms moment of flexure stress.And the size of this stress is proportional to axle head 311 ' circle and beats, and motor shaft 31 ' is more long, and jerk value is more big.Long-term use can cause the castellated shaft fracture unavoidably.
The utility model content
The purpose of this utility model is to provide the hybrid architecture of a kind of handling ease, single shaft moment of torsion stack that the motor shaft force-bearing situation is good.
For achieving the above object, technical solution of the present utility model is:
The utility model is a kind of hybrid architecture of single shaft moment of torsion stack, and it comprises driving engine, power-transfer clutch, bindiny mechanism, drive motor; Described driving engine is connected with drive motor power by power-transfer clutch, bindiny mechanism; Described bindiny mechanism comprises casing, transition bearing and transition axis, transition axis is set in the casing and the transition axis middle part is nested with in the transition bearing, the transition bearing is installed on the bearing seat at casing middle part, one end of transition axis stretches in the power-transfer clutch and by center bearing pilot bearing and locatees, an end of motor shaft is connected the external transmission shaft of the other end of motor shaft on the drive motor on the other end of transition axis and the drive motor; The motor shaft of described drive motor is by two rotatable being installed in the electric machine casing of motor bearings.
Transition axis one end of described bindiny mechanism is the axis hole that has keyway; The motor shaft of described drive motor is plugged in this axis hole and passes through the spline radial location.
After adopting such scheme, because the utility model has been set up a bindiny mechanism, motor shaft is subjected to two bearings, eliminated the location of crossing of original design, can the overstriking of motor castellated shaft be improved the moment of torsion that motor shaft can bear, and need not change model engine power-transfer clutch castellated shaft size.So have handling ease, advantage that the motor shaft force-bearing situation is good.
Below in conjunction with the drawings and specific embodiments the utility model is further described.

The specific embodiment
As shown in Figure 3, the utility model is a kind of hybrid architecture of single shaft moment of torsion stack, and it comprises driving engine 1, power-transfer clutch 2, bindiny mechanism 3, drive motor 4.
Described driving engine 1 is connected with drive motor 4 power by power-transfer clutch 2, bindiny mechanism 3.
As shown in Figure 3, Figure 4, described bindiny mechanism 3 comprises casing 31, transition bearing 32 and transition axis 33.Described transition axis 33 is set in the casing 31 and transition axis 33 middle parts are nested with in transition bearing 32, transition bearing 32 is installed on the bearing seat at casing 31 middle parts, one end of transition axis 33 stretches in the power-transfer clutch 2 and by center bearing pilot bearing 21 and locatees, the other end of transition axis 33 is the axis hole 331 that has keyway, one end of the motor shaft 41 of drive motor 4 is plugged in this axis hole 331 and by spline 411 radial locations, the external transmission shaft 5 of the other end of motor shaft 41 on the drive motor 4.
The motor shaft 41 of described drive motor 4 is by two motor bearingss 412,413(as shown in Figure 5) rotatable being installed in the electric machine casing 42.
Principle of work of the present utility model:
Driving engine 1 passes to bindiny mechanism 3 by power-transfer clutch 2 with propulsion source, and bindiny mechanism 3 passes to propulsion source drive motor 4 again, passes to wheel finally by crossing transmission shaft 5.Drive motor 4 belongs to indirect transfer relatively.
Force analysis of the present utility model:
With reference to shown in Figure 3, motor shaft 41 is supported by two motor bearingss 412,413 as Fig. 5, has eliminated the location of crossing of original design.Because the utility model can improve the overstriking of motor castellated shaft the moment of torsion that motor shaft 41 can bear, and need not change model engine power-transfer clutch castellated shaft size by increasing a bindiny mechanism 3 transition, has solved drive motor off-axis problem.
Emphasis of the present utility model just is: set up a bindiny mechanism between power-transfer clutch and drive motor.
The above, it only is the utility model preferred embodiment, so can not limit the scope that the utility model is implemented with this, i.e. the equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
