Problems solved by technology

[0004] However, because the principle of the metal pulley CVT is to control the position of the pulley to control the width of the V-shaped groove, and finally to control the radius of rotation to achieve CVT, because in the range of speed change, the transmission of torque They are all friction transmission, so the manufacturing process requirements are getting higher and higher, and the cost is also increasing. At the same time, a disadvantage of friction transmission is that the range of friction can be limited. The existing technology has basically made a single pulley It is difficult to make a breakthrough in this aspect if the friction force is maximized
Therefore, the torque of the continuously variable transmission cannot be effectively broken through under the technical conditions of the existing single pulley, and the metal pulley continuously variable transmission cannot be applied to automobiles with high torque so far.

Embodiment Construction

[0013] figure 1 The positions of the metal pulley and the hydraulic device in the low-speed state of the present invention are briefly shown. In the low-speed state, the steel belt of the driving wheel has a smaller radius, and the steel belt of the driven wheel has a larger radius.

[0014] In the driving wheel, the position of the driving wheel (1) is fixed, and the pressure wheels (5) and (12) are in the middle of the driving shaft (11). At this time, because the driving wheel (1) and the pressure wheel (5) and (12) Far apart, therefore, steel band (3) and (13) are close to drive shaft (11), that is, the stressed radius of (11) this moment is very little.

[0015] Among the driven wheels, the position of the driven wheel (6) is fixed, the positions of the resistance elements (9) and (16) are fixed, the pressure wheels (7) and (14) are close to the driven shaft (6), and the two positions are relatively close. Belts (3) and (13) will be far away from the driven shaft (10), ...

Abstract

The invention discloses a stepless speed changing device capable of bearing high torque. The stepless speed changing device is provided with two or more pairs of belt pulleys, wherein the belt pulleys are in hard connection through connecting shafts, and a relative or opposite side of each belt pulley can be moved; and in a driving wheel, the movable belt pulleys on both sides can be moved by controlling the pressure of a hydraulic system to control the width of each V-shaped groove, so that the positions of more than two metal bands are moved to realize different rotating radii.

Description

technical field [0001] The present invention relates to the field of continuously variable transmission as claimed in claim 1, which has been widely used in mechanical fields including automobile gearboxes. Background technique [0002] The transmission of the car is an important part of the car. The transmission occupies a very important position in the cost of the car. There are various transmissions in the existing car transmission field. Among them, the continuously variable transmission has become a popular choice for many cars because of its high comfort and high fuel economy. Manufacturer's research objectives. [0003] There are many forms of existing continuously variable transmissions, among which the metal pulley type continuously variable transmission has the longest development time, the widest range of applications and the most mature technology. [0004] However, because the principle of the metal pulley CVT is to control the position of the pulley to control...
