Problems solved by technology

Due to the use of rubber V-belt as the transmission body, the problems brought about are: the transmitted torque and power are limited, and it is not suitable for application in small-scale transmission mechanisms.
Therefore, this continuously variable transmission can only be used in low-power mechanical transmission

Embodiment

[0026] Embodiment: The purpose of this embodiment is to change the diameter of the active variable diameter hub 19 and the passive variable diameter hub 20 with the same structure, and realize the stepless speed change from the input shaft 13 to the output shaft 18 by the frictional traction force of the V-belt 14 .

[0027] Such as figure 1 , 2 , Shown in 4, the variable diameter process of active variable diameter hub 19 is realized by following structure: assembly synchronous belt pulley 2 is assembled on the left end shaft shoulder of active variable pitch screw mandrel 10, and synchronous belt 1 is assembled on synchronous belt pulley 2. The input shaft 13 is coaxially assembled with the active pitch variable screw rod 10 , and the sliding sleeve 7 is sleeved on the input shaft 13 and can slide along the axial direction of the input shaft and 13 . Sixteen inner hinges are evenly distributed on the sliding sleeve 7, and the inner hinges on the sliding sleeve 7 and the ou...

Abstract

The invention relates to the field of mechanical transmission stepless speed change devices and particularly relates to a stepless speed change device with a transmission diameter variable wheel hub. The stepless speed change device with the transmission diameter variable wheel hub is characterized by comprising an active diameter variable wheel hub, and a passive diameter variable wheel hub. The active diameter variable wheel hub and the passive diameter variable wheel hub are same in structure. The active diameter variable wheel hub and an input shaft are in coaxial rotation. The passive diameter variable wheel hub and an output shaft are in coaxial rotation. Each two sides of the active diameter variable wheel hub and the passive diameter variable wheel hub have an umbrella-shaped structure. The center portion of each umbrella-shaped structure is hinged with a sliding sleeve. The sliding sleeve is sleeved on the periphery of a pitch varying screw rod. The pitch varying screw rod of the active diameter variable wheel hub is connected with the pitch varying screw rod of the passive diameter variable wheel hub through a synchronous belt to form a synchronous rotation. The active diameter variable wheel hub forms a synchronous rotation with the passive diameter variable wheel hub through a belt. The stepless speed change device with the transmission diameter variable wheel hub has the advantages of being capable of being used for all kinds of stepless speed change devices, improving the transmission torque and power of the stepless speed change devices and improving allowable value of speed limit.

Description

technical field [0001] The invention relates to the field of mechanically driven continuously variable transmissions, in particular to a belt-driven variable-diameter hub-type continuously variable transmission. Background technique [0002] The mechanical continuously variable transmission adopts the transmission belt and the driving and driven wheels with variable working diameters to transmit power, realize the continuous change of the transmission ratio, and achieve the best match of the required mechanical transmission. Industrialized mechanical continuously variable transmissions have four categories of friction type, chain type, pulsation type and belt type and about dozens of basic structural types. [0003] Typical types of friction continuously variable transmissions include: planetary cone-disc type; planetary ring-cone type; cone-disk ring-disc type; ball type, etc. Tooth chain continuously variable transmissions include: slide chain; roller chain; chain win...
