Description
Technical field
The present invention relates to automotive transmission field, especially, it is related to a kind of novel stepless variable-speed device metal tape, can be effective
Reduce the friction loss of buncher.
Background technology
The speed of metal band type stepless speed variator can make power source continuous firing in optimal economic point than consecutive variations characteristic,
And it is a kind of preferable vehicle transmission gear, in vehicle with splendid fuel economy and comfortableness without shift shock
It is widely applied.
However, compared with other kinds of transmission of vehicle, the gear of metal band type stepless speed variator is friction
Transmission, its friction loss is higher, and this counteracts the economic sexual clorminance that variable speed is brought to a certain extent.Gear rubs
The owner of lost property that wears will include friction loss between friction loss, sheet metal and the belt wheel conical surface between steel loop group and sheet metal and each
Friction loss between layer steel loop.As illustrated in fig. 1 and 2, wherein steel loop friction loss be due to the existing pitch circle crest line 18a of sheet metal with
There is spacing between the inner surface of steel loop group 2 so that existing sheet metal 1a exists caused by relative slide with steel loop group 2.
Fig. 1 and 2 is existing metallic strip structures, is made up of existing sheet metal 1a and two beam steel loop groups 2 being arranged symmetrically, steel
The inner surface of ring group 2 is contacted with existing sheet metal 1a saddles face 31.There are the first plane 12a and below existing sheet metal 1a saddles face 31
In the existing pitch circle crest line 18a that two plane 15a are crossed to form, practice, existing pitch circle crest line 18a forms one into after fillet
Small circular arc faceted pebble, the effect of the circular arc faceted pebble is to provide a linear contact lay face, i.e., one rotation for the cooperation of front and rear sheet metal
Center, each sheet metal can be used as fulcrum slight oscillatory using the linear contact lay face.Metal tape is operated in the arc section with pulley contact
When, the second plane 15a of each sheet metal is brought into close contact, and each existing existing nodel line 20a of sheet metal 1a form continuous arcuation pitch circle
With pulley contact, stable speed ratio is formed, when existing sheet metal 1a is operated in straightway, the first of each existing sheet metal 1a is flat
Face 12a is brought into close contact, the existing aligned states of sheet metal 1a, is used to transmit torque to form stable pushing force.By with
Upper principle analysis is understood, in existing sheet metal structure, is arranged on the first plane 12a of the lower section of saddle face 31 so that steel loop inner surface
Spacing is certainly existed between saddle face 31.
Fig. 3 is the motion schematic diagram of existing metal tape.The input angular velocity of driving pulley 4 for defining gear is ω1, it is main
The pitch radius of movable belt pulley 4 is R1, the Output speed of driven pulley 5 is ω2, the pitch radius of driven pulley 5 is R2, existing sheet metal
Distance between 1a pitch circle lines 32 and the inner surface of steel loop group 2 is h.The speed of metal tape is represented by than i：
I=ω1/ω2=R2/R1 1-1)
Because the inner surface of steel loop group 2 is contacted with existing sheet metal 1a saddle face 31, it is now assumed that the inner surface of steel loop group 2 and saddle face
Without relative slip between 31, then the linear velocity of the inner surface of steel loop group 2 is represented by driving pulley 4：
υ1=ω1(R1+h) 1-2
The linear velocity of the inner surface of steel loop group 2 is represented by driven pulley 4：
υ2=ω2(R2+h) 1-3
Convolution 1-1,1-2 and 1-3 formula are understood, make υ1=υ2Prerequisite be i=1.In the case of i ≠ 1, that is, lead
In the case of the radius of movable belt pulley 4 and the radius of driven pulley 5 are unequal, the speed of steel loop inner surface on driving pulley 4 and driven pulley 5
Degree is inconsistent, there is relative slip, the actual speed of steel loop group 2 between this inner surface of explanation steel loop group 2 and the saddle face 31 of sheet metal 3
Positioned at υ1With υ2Between.Because steel loop group 2 is tensioned in the course of the work, there is friction between its inner surface and saddle face 31
The product of power, frictional force and relative sliding velocity is fricting loss power.From the foregoing, it will be observed that in existing structure, due to existing
There is spacing, rubbing between existing sheet metal 1a and steel loop group 2 between the existing nodel line 20a of sheet metal 1a and the inner surface of steel loop group 2
Mistake of wearing is inevitable.
The content of the invention
In order to reduce the friction loss of metal band type stepless speed variator, the invention provides a kind of new metal tape knot
