Description

Transmission belt of movable-plate continuously variable transmission

Technical Field

The present invention relates to a power transmission belt, and more particularly, to a power transmission belt suitable for a continuously variable transmission.

Background

At present, friction transmission is mostly adopted for a transmission belt or a chain of the continuously variable transmission, and the transmission belt or the chain has the defects of small transmission torque, low bearing capacity, poor overload resistance, impact resistance, high sliding rate and low mechanical efficiency; some have the phenomena of pulsating output and discontinuous power flow; the transmission power needs to increase a larger pressing force to the transmission belt so as to increase the friction force, thereby causing larger power loss, increasing the load of each bearing and easily damaging the bearing; the effective contact surface for transmitting power is small, theoretically, the effective contact surface is in line contact or point contact, the local stress is large, the working surface is easy to scratch or glue, the transmitted power is limited, the service life is short, and the application range is limited. The gleitbretter chain relies on groove face sprocket and gleitbretter chain with accurate mesh mode transmission power, has that the rate of slide is low, the transmission is accurate, wear-resisting, advantage such as impact capacity height, nevertheless because the gleitbretter of gleitbretter chain is the discontinuous arrangement on the gleitbretter chain, when the gleitbretter of gleitbretter chain and the groove meshing on groove face sprocket surface, only a slice or a few atress's phenomenon can appear, consequently easily leads to the gleitbretter rupture to damage.

Disclosure of Invention

In order to overcome the defects of the transmission belt of the continuously variable transmission, the invention provides the transmission belt of the continuously variable transmission with the movable plates, so as to overcome the defects of the transmission belt of the continuously variable transmission.

The technical scheme adopted by the invention for solving the technical problems is as follows: a continuously variable transmission belt (1) with a movable plate, comprising: the annular bearing body (2) and the transverse component (3) installed on the annular bearing body (2) are also called sliding sheets, and the annular bearing body is characterized in that: the transverse components (3) are continuously arranged and installed on the annular bearing body (2) and can transversely move left and right on the axis of the annular bearing body (2), so that tooth shapes with any shape and size can be formed on the surfaces of two sides of the transmission belt, and transmission teeth are arranged on the surfaces of the transmission wheels. The transmission wheel is a conical surface structure, namely a conical disc, the shape of transmission teeth or tooth grooves on the surface of the transmission wheel is an approximately inverted trapezoid shape, wherein the transmission teeth or tooth grooves gradually become narrower and wider from one side of the conical disc close to the circle center to the outer side of the conical disc, namely the width of the transmission teeth or tooth grooves on the conical disc is different from that of the transmission teeth or tooth grooves at different height positions from the circle center side to the outer side of the conical disc, and a common transmission belt cannot adapt to the width variation of the transmission teeth or tooth grooves at different heights of the conical disc. In the transmission process, the transmission teeth on the conical disc are contacted with the side surface of the transmission belt, the transmission teeth at a certain height position from one side of the circle center to the outer side of the conical disc on the conical disc can push a plurality of sliding sheets which can transversely move on the transmission belt in the width range contacted by the transmission teeth of the conical disc at the height position into the tooth grooves of the conical disc, so that the deformed teeth on the surfaces of two sides of the transmission belt are meshed with the transmission teeth or the tooth grooves on the surface of the transmission wheel, the width of the deformed teeth on the surfaces of two sides of the transmission belt is adapted to the width change of the transmission teeth or the tooth grooves from one side of the circle center to the outer side of the conical disc on the conical disc, and therefore the meshed transmission of the transmission belt and the; the annular bearing body groove (4) is arranged on two outer sides of the transverse component (3), the annular bearing body (2) is arranged in the annular bearing body groove (4), the hoop hoops (16) sleeved and bound on the annular bearing body (2) are arranged on the annular bearing body (2) at intervals along the annular direction, the inner sides of the fixing clamp feet (21) at two ends of the fixing clamp (7) are respectively fixedly connected with the outer sides of the two hoop hoops (16) in the left and right corresponding annular bearing body grooves (4) on the transverse component (3), the lower ends of the hoop hoops (16) and the fixing clamp feet (21) are embedded in the fixing clamp sliding grooves (17), so that the transverse component (3) is prevented from longitudinally deflecting in the moving process (the longitudinal deflection of the transverse component can lead to the neck of the transverse component to contact with the annular bearing body, and the annular bearing body is prevented from being broken. The shoulders (20) of the transverse members (3) which the fixing clip legs (21) cross in the axial direction of the drive belt are shorter than the shoulders (20) of the transverse members (3) which the fixing clip legs (21) are arranged at the front and rear in the axial direction of the drive belt, so that the transverse members (3) arranged on the annular carrier body (2) naturally form the fixing clip slide grooves (17). In the process of stepless speed change transmission, if the surface of the transmission wheel is provided with transmission teeth, the shape of the transmission teeth on the surface of the transmission wheel changes along with the change of the position of the transmission belt when the transmission wheel performs diameter change movement, and the transmission belt can adapt to the change, thereby realizing the tooth-meshed stepless speed change transmission.

The invention has the beneficial effects that: the stepless speed changer transmission belt can realize tooth-meshing stepless speed change transmission, and overcomes the defects of small transmission torque, low bearing capacity, poor overload resistance, impact resistance, high sliding rate and low mechanical efficiency of the conventional friction-driven stepless speed changer transmission belt; some of the devices have the defects that the pulsating output and the power flow are discontinuous, the transmission power needs to increase larger pressing force to the transmission belt, the power loss is large, the bearing load is increased, and the device is easy to damage; limited transmission power, short service life and limited application range. Meanwhile, the phenomenon that the sliding pieces of the sliding piece chain are arranged on the sliding piece chain in a non-continuous mode and are broken and damaged due to the fact that only one or a few sliding pieces are stressed can be avoided. The invention breaks through the limitation that the traditional stepless speed changer is driven by the friction force between the transmission belt and the transmission wheel, and overcomes the technical problem that the transmission belt of the stepless speed changer is always hopefully solved but is not successfully achieved.
