Abstract

The invention relates to a continuously variable transmission. The transmission at least comprises four arc racks and a fixed disc; the lower end face of each arc rack is connected with a screw which is integrally formed with the corresponding arc rack, screw positioning holes with the number equal to the number of the screws are averagely distributed in the side face of the fixed disc in the circumferential direction, a gap for containing a driven wheel is formed in the top end of each screw positioning hole, the driven wheel coaxial with the corresponding screw positioning hole is arranged at the position of each gap, the outer side of each driven wheel is engaged with the output end of a motor, and the motor is mounted on the fixed disc through a motor supporting plate; each screw is engaged with the inner side of the corresponding driven wheel. The motor is adopted to drive the driven wheels to drive the screws to vertically stretch out and draw back, the variable diameter effect of the arc racks is achieved, and the transmission has the beneficial effects of being simple in structure, stable in transmission, large in speed adjusting range, large in transmission power and the like and is particularly suitable for bicycles and tricycles and also capable of being used for automobiles, ships, power generation parts, machine tools and other devices.

Description

【Technical field】 [0001] The invention relates to the technical field of mechanical transmission, in particular to a continuously variable transmission. 【Background technique】 [0002] In various motor vehicles, bicycles, and mechanical equipment such as rotary beds, transmissions are widely used to change the speed ratio of input and output to achieve the desired acceleration and deceleration. [0003] Traditional transmissions are mainly made up of gears of different sizes, such as automobile manual or automatic transmissions, which have 4 to 5 levels of speed change. Each level of speed change must be transferred from the previous level to the next level, and then from the latter to another. Level, the operation is extremely complicated, and there will be a short-term failure when changing. As far as the transmission of a bicycle with a relatively simple structure is concerned, a sprocket with a plurality of sequentially changing diameters called a tower wheel is usual...
