Abstract
The utility model discloses a motor shaft used for a bus with mixed power. The motor shaft comprises a motor shaft body and a spline shaft. A motor flange is sleeved outside the motor shaft body. One end of the motor shaft body is provided with an internal spline. One end of the spline shaft is provided with an external spline corresponding to the internal spline. One end of the spline shaft is sleeved inside the internal spline end of the motor shaft body through the external spline, and a combustion motor flange is sleeved outside the other end of the spline shaft. According to the motor shaft, an existing integral type motor shaft is changed into the motor shaft body and the spline shaft which are in split type, and the motor shaft body is connected with the spline shaft through splines. When the spline shaft and a combustion motor shaft are not coaxial, the clearance between the splines connecting the motor shaft body and the spline shaft can automatically adjust the direction of the spline shaft, and therefore the coaxiality requirement of a motor installing flange and a combustion motor flywheel is reduced. Meanwhile, the split type motor shaft can further save materials, reduce cost and labor intensity, and improve working efficiency.
Description
Technical field
The utility model relates to a kind of motor shaft, relates in particular to a kind of motor shaft that is used for mixed power public transport big bus.
Background technique
The axle of an existing hybrid electric big bus main drive motor normally end is connected with clutch through motor flange, and the other end links to each other with the flywheel of internal-combustion engine through the internal-combustion engine flange, in the using process, and the easily broken axle in the spline position of motor shaft extension.Its reason mainly is: 1, the coaxality of the flywheel of the motor shaft extension cylindrical of motor shaft and internal combustion engine flywheel connecting end and internal-combustion engine is relatively poor, during installation, also has on the output shaft of a little bearing fixing at engine at the relative axle head of internal-combustion engine.Because the coaxality of shaft extension cylindrical and internal-combustion engine mounting flange seam can not be zero, so motor whenever turns around, shaft extension will receive the bending compressing of one-period property.When the coaxality of shaft extension cylindrical and internal-combustion engine mounting flange seam was poor more, this flexural stress was big more.After long-time continuous is used, in this frequent and powerful flexural stress, will produce tiredly on the surface of the shaft extension (spline position) of motor shaft, surface crack appears, finally cause tired off-axis.2, possibly have defective in less, the material of the spline diameter of the motor shaft extension of existing and clutch engagement, also be to influence the factor that shaft extension ruptures.
Summary of the invention
The purpose of the utility model provides and does not a kind ofly change the integral installation size, and motor shaft not easy-rupturing be used for the motor shaft of mixed power public transport big bus.
For realizing above-mentioned purpose; A kind of motor shaft that is used for mixed power public transport big bus of the utility model, it comprises motor shaft body and splined shaft, the motor shaft body is arranged with motor flange outward; Motor shaft body one end is provided with internal spline; The corresponding internal spline of splined shaft one end is provided with external splines, and splined shaft one end is inserted in the internal spline end of motor shaft body by external splines, and the splined shaft the other end is arranged with the internal-combustion engine flange outward.
The said splined shaft the other end is connected by spline fitted with the internal-combustion engine flange.
Adopt the motor shaft of the utility model; Make existing all-in-one-piece motor shaft into split type motor shaft body and splined shaft; The motor shaft body is connected through spline with splined shaft; When splined shaft and internal combustion engine shaft disalignment, the gap of the spline that the motor shaft body is connected with splined shaft is the direction of adjustment splined shaft automatically, reduces the coaxality requirement of motor mounting flange and internal combustion engine flywheel.Simultaneously, all right economical with materials of split type motor shaft reduces cost, and reduces labor intensity, increases work efficiency.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation:
Fig. 1 is used for the structural representation of the motor shaft of mixed power public transport big bus for the utility model.
Embodiment
As shown in Figure 1; A kind of motor shaft that is used for mixed power public transport big bus of the utility model, it comprises motor shaft body 1 and splined shaft 2, the motor shaft body 1 outer motor flange 3 that is arranged with; Motor shaft body 1 one ends are provided with internal spline 11; The corresponding internal spline 11 of splined shaft 2 one ends is provided with external splines 21, and splined shaft 2 one ends are inserted in internal spline 11 ends of motor shaft body 1 by external splines 21, and splined shaft 2 the other ends are arranged with internal-combustion engine flange 4 outward.
Said splined shaft 2 the other ends and internal-combustion engine flange 4 are connected by spline fitted.
Adopt the structure of the utility model, with prior motor axle separated into two parts, i.e. motor shaft body 1 and splined shaft 2; Motor shaft body 1 is connected with clutch by motor flange 11; Splined shaft 2 is connected with internal combustion engine flywheel by internal-combustion engine flange 21, and motor shaft body 1 and splined shaft 2 are connected through spline, when splined shaft 2 during with the internal combustion engine shaft disalignment; The gap of the spline that motor shaft body 1 is connected with splined shaft 2 is the direction of adjustment splined shaft 2 automatically; Avoid splined shaft 2 to bear frequent flexural stress, thereby guarantee the working life of splined shaft 2, reduce the coaxality requirement of motor mounting flange 11 and internal combustion engine flywheel.
After making the prior motor axle into motor shaft body 1 and splined shaft 2 two-part, because of less demanding, so motor shaft body 1 can use common material to motor shaft body 1; Because of splined shaft 2 is stressed big, so the splined shaft 2 of thin diameter uses high-strength material, all adopt high-strength material to compare with the prior motor axle, practiced thrift great amount of cost.Simultaneously; Because of the prior motor axle is formed in one, so the splined shaft 2 of thin diameter is formed by the bigger material cutting of diameter, the utility model is with after motor shaft body 1 and splined shaft 2 splits; Splined shaft 2 can adopt the material of minor diameter to carry out a small amount of smear metal moulding; Not only can save material, reduce the labor intensity of processing, and processing technology be convenient.
