Description
Technical field
The present invention relates to pure electric automobile technical fields, more particularly, to a kind of pure electric automobile CVT retarder.
Background technique
Single reduction gear used by overwhelming majority pure electric automobile at present, fixed speed ratio can not usually combine pure
The dynamic property and economy of electric car, vehicle power performance depend entirely on driving motor, turn when speed reaches motor output
There is no room for promotion after the fast limit, speed is restricted, and high speed economy is not high；Simultaneously, because fuel oil engine itself can not
It realizes positive and negative rotation, therefore contains idle pulley, clutch and advance, reverse gear mechanism inside traditional CVT retarder, overall structure is more multiple
It is miscellaneous.
Summary of the invention
In view of the shortcomings of the prior art, technical problem to be solved by the invention is to provide a kind of pure electric automobile CVT to subtract
Fast device, it is adjustable to reach transmission speed ratio, and the simple purpose of structure.
In order to solve the above-mentioned technical problem, the technical scheme adopted by the invention is as follows:
Pure electric automobile CVT retarder, including input shaft and output shaft, further include driving wheel and driven wheel, described
Driving wheel is connected with input shaft, and driven wheel is connected with output shaft, is connected between the driving wheel and driven wheel by transmission belt, institute
It states driving wheel and driven wheel is the driving wheel of reducing.
Further, the input shaft is connected with the driving motor shaft of electric car.
The transmission belt is steel band.
The driving wheel and driven wheel are sprocket wheel, form drive sprocket and driven sprocket.
The output shaft is connected with the input terminal of the differential mechanism on electric car, the output end of differential mechanism and electric car
Drive shaft is connected.
The input shaft is coaxially connected with the shaft of driving motor.
The steel band is connected to form by one group of steel disc, is hinged and connected between adjacent steel disc by connecting shaft.
It further include connected hydraulic pump and fluid torque-converter, the drive sprocket and driven sprocket pass through fluid torque-converter
Realize diameter change adjustment.
Compared with prior art, the present invention having the advantage that
The pure electric automobile is designed rationally with CVT reducer structure, and sprocket wheel is adjusted realization by fluid torque-converter and passes
Dynamic than adjustable, vehicle dynamic property and economy can be taken into account, and high speed economy improves；Retarder internal structure simplifies, and passes through electricity
Machine positive and negative rotation can be realized vehicle and advance, fall back, by expanding driving motor high efficiency range, to improve vehicle continuation of the journey.
Detailed description of the invention
Content expressed by each width attached drawing of this specification and the label in figure are briefly described below:
Fig. 1 is reducer structure schematic diagram of the present invention.
In figure:
1. drive sprocket, 2. input shafts, 3. hydraulic pumps, 4. transmission belts, 5. driven sprockets, 6. differential mechanisms.
Specific embodiment
Below against attached drawing, by the description of the embodiment, making to a specific embodiment of the invention further details of
Explanation.
As shown in Figure 1, pure electric automobile CVT retarder, including reducer input shaft 2, reducer output shaft, active
Wheel, driven wheel, hydraulic pump 3 and fluid torque-converter.
Driving wheel is connected with input shaft 2, and driven wheel is connected with output shaft, passes through transmission belt 4 between driving wheel and driven wheel
It is connected, driving wheel and driven wheel are the driving wheel of reducing.Accordingly reduce as active wheel diameter increases driven wheel diameter, comes real
Existing transmission ratio is adjustable.
Input shaft is connected with the driving motor shaft of electric car；Preferably, the shaft of input shaft and driving motor is coaxial
Setting is connected by spline.
Output shaft is connected with the input terminal of the differential mechanism 6 on electric car, the drive of the output end and electric car of differential mechanism 6
Moving axis is connected.
Transmission belt 4 is steel band；Preferably, steel band is connected to form by one group of steel disc, passes through connecting shaft between adjacent steel disc
It is hinged and connected.
Driving wheel and driven wheel are sprocket wheel, form drive sprocket 1 and driven sprocket 5.Drive sprocket and driven sprocket are equal
Diameter change adjustment is realized by fluid torque-converter, and hydraulic pump provides pressure change to fluid torque-converter, and control is easy.
In implementation process, sprocket wheel is fixed on Novel CVT reducer input shaft and output shaft respectively, two sets of sprocket wheels pass through
Steel band connects, and torque and revolving speed are forwarded to the sprocket wheel on output shaft, two sets of sprocket wheels itself by steel band by the sprocket wheel on input shaft
Diameter is adjusted in retarder work process by fluid torque-converter, and transmission ratio just becomes adjustable；Reducer input shaft and drive
Dynamic motor shaft shares, and is connected by spline, output shaft is connected with drive shaft by differential mechanism.
Based on above structure, the pure electric automobile with Novel CVT retarder compared with existing retarder, the reduction train of vehicle
System becomes adjustable speed ratio from fixed speed ratio, and vehicle dynamic property and economy can be taken into account, and high speed economy improves；Inside retarder
Structure simplifies, and vehicle advance can be realized by motor positive and inverse, fall back, by expanding driving motor high efficiency range, to mention
High vehicle continuation of the journey.
It above are only and preferred embodiments of the present invention are illustrated, above-mentioned technical characteristic can form multiple hairs in any combination
Bright example scheme.
The present invention is exemplarily described above in conjunction with attached drawing, it is clear that the present invention implements not by aforesaid way
Limitation, if use the improvement for the various unsubstantialities that conception and technical scheme of the invention carry out, or it is not improved will
Conception and technical scheme of the invention directly apply to other occasions, within the scope of the present invention.
