Abstract
The invention relates to a novel CVT transmission belt which has the advantages of reliable transmission and wide transmission ratio range. The technical scheme is that: the transmission belt comprises two bundles of metal bands and a frictional pushing sheet, wherein the two bundles of metal bands pass through the frictional pushing sheet; the metal bands are positioned on a saddle-shaped surface of the frictional pushing sheet; the transmission belt is characterized in that the metal bands consist of steel wire rings; and the saddle-shaped surface of the frictional pushing sheet and the pitch circle of the transmission belt are positioned on the same plane.
Description
Technical field
The present invention relates to a kind of Novel CVT transmission belt.
Background technique
In the prior art, as shown in Figure 1, traditional CVT driving belt comprises two bundle metal tapes and friction push jack, two bundle metal tapes 1 pass friction push jack 2, metal tape 1 is positioned on the saddle face of friction push jack 2, and metal tape is made of the steel disc ring, and every bundle metal tape is that the steel disc ring of 0.2mm is formed by 9-12 sheet thickness.When skew takes place in metal tape, both sides steel disc rings can be simultaneously in the friction push jack deflection left or to the right, after side-play amount reaches certain value, meeting of steel disc ring side and pulley 3 inclined-planes produce friction, because steel disc is extremely thin, any contact of side is collided with and is all very easily caused the steel loop fracture failure, influences the reliability of work, and has limited the transmission speed ratio scope.
In addition, because friction push jack saddle face and driving belt pitch circle 4 be (circle that the driving belt pitch circle is formed for the theoretical contact points of friction push jack and pulley Surface of action) not at grade, distance between the two is generally more than 1mm, this just causes the be in operation linear velocity of friction push jack saddle face and driving belt pitch circle of driving belt inconsistent, making to be positioned at the steel disc ring on the friction push jack saddle face and to rub has relative linear velocity poor between push jack saddle face, produce friction energy loss, influence transmission efficiency.
Summary of the invention
Goal of the invention of the present invention is to provide a kind of Novel CVT transmission belt, and reliable transmission has bigger transmission speed ratio scope.
Realize the technological scheme of the object of the invention:
A kind of Novel CVT transmission belt comprises two bundle metal tapes and friction push jack, and two bundle metal tapes pass the friction push jack, and metal tape is positioned on the saddle face of friction push jack, and it is characterized in that: metal tape is made of the steel wire ring.
The saddle face and the driving belt pitch circle of friction push jack are positioned at same plane.
The both sides sealing of friction push jack, the wrapped wire endless belt.
The steel wire endless belt has 3 to 8 layers.
The steel wire endless belt has 6-10 steel wire ring for every layer.
The steel wire endless belt has 4 layers.
The beneficial effect that the present invention has:
Metal tape of the present invention adopts the steel wire ring to replace existing steel disc ring, because the steel wire ring is made up of tiny round wire, the opposing contact of round wire side is collided with and the ability of frictionally damage exceeds steel disc greatly, simultaneously, because the both sides sealing of friction push jack, the wrapped wire ring, make the steel wire ring can not produce and contact the phenomenon of colliding with the pulley inclined-plane, can be offset by the bigger metal tape of opposing, transmission is more reliable, and can obtain bigger transmission speed ratio scope, the transmission speed ratio scope of existing CVT driving belt is 5-6, and transmission speed ratio scope of the present invention can reach more than 8.And the present invention adopts the steel wire ring can also reduce the manufacture cost of CVT driving belt greatly.Simultaneously, the saddle face and the driving belt pitch circle of friction push jack are positioned at same plane, and it is poor to have eliminated at steel wire ring on the saddle face and the linear speed between the saddle face, has effectively avoided friction energy loss, can further improve transmission efficiency more than 4%.

Embodiment
As shown in Figure 2, two bundle metal tapes 5 pass friction push jack 6, and metal tape is positioned on the saddle face of friction push jack, metal tape is made of the steel wire ring, and the steel wire endless belt has 3 to 8 layers, is 4 layers in the present embodiment, the steel wire endless belt has 6-10 steel wire ring for every layer, and every layer has 7 steel wire rings in the present embodiment.
In another preferred embodiment of the present invention, the saddle face of friction push jack 6 and driving belt pitch circle 7 are positioned at same plane (circle that the driving belt pitch circle is formed for the theoretical contact points of friction push jack and pulley Surface of action), the both sides sealing of friction push jack, wrapped wire endless belt.
