Problems solved by technology

Metal V-belt CVT is compact in structure, easy to control, and capable of high-speed transmission, but it has many components, complex structure, high machining accuracy requirements, and cannot transmit excessive torque. It is easy to slip when accelerating rapidly and transmitting large torque, so it is often used Variable speed transmission for smaller displacement engines

Embodiment Construction

[0023] like figure 1 , figure 2 As shown, the ring cloth bevel wheel continuously variable transmission device of the present invention includes a driven shaft 6 located in the center, and a plurality of driving shafts 10 are arranged around the driven shaft 6, six in this embodiment, and the driving shafts 10 are arranged along the The rings are evenly distributed around the driven shaft 6 . Both ends of the driven shaft 6 and the driving shaft 10 are respectively supported on the bases 1 and 11 through bearings.

[0024] A cylindrical friction wheel 5 is sleeved on the driven shaft 6, and the surface of the driven shaft 6 is provided with a longitudinal chute, and the inner hole of the cylindrical friction wheel 5 is also provided with a spline groove, so the cylindrical friction wheel 5 and the driven The connection mode between the shafts 6 is spline fit, and the cylindrical friction wheel 5 and the driven shaft 6 can move axially, but cannot rotate relatively.

Abstract

The invention discloses a stepless speed change device of circularly arranged cone pulleys, comprising a driven shaft and a driving shaft arranged around the driven shaft. The driven shaft is provided with a columnar friction pulley capable of axially moving, which is connected with a position control device; each driving shaft is provided with a conical friction pulley of which the inner conical face contacts with the columnar face of the columnar friction pulley in parallel to form a friction driving face. The stepless speed change device drives through the friction driving face between the conical friction pulley and the columnar friction pulley and can drive relatively high torque in a use rotation speed range. When position of the columnar friction pulley is in stepless change, drive ratio between the conical friction pulley and the columnar friction pulley will be also in corresponding stepless change so as to realize stepless speed change. The stepless speed change device has advantages of simple and compact structure, reliable property, low cost and so on.

Description

technical field [0001] The invention relates to a continuously variable transmission device. Background technique [0002] The known CVT transmission is usually divided into two types: traction transmission and friction transmission. The traction transmission transmits power through the molecular force of the liquid medium between the contact surfaces; the friction transmission transmits power through the friction force of the contact surfaces. The typical application of the traction drive continuously variable transmission is the traction ring type continuously variable transmission. Its advantage is that multiple sets of traction rings can be arranged in series, the transmitted torque is large, and the efficiency is high. High, low transfer speed. The typical application of the friction CVT is the metal V-belt CVT. By axially adjusting the width of the V-belt groove, the radius of the actual contact surface between the driving wheel and the driven wheel V-belt is controll...
