Embodiment Construction

[0018] In Fig. 1, the detachable fixed inner conical friction wheel (3) is controlled by the pressure control mechanism (III) to compress or separate it, so as to indirectly load or unload the conical sun gear (1) The pressure makes the conical sun gear (1) and the friction wheel of the planetary gear system (2) produce friction, so that the friction wheel of the planetary gear system (2) rotates, and at the same time, it also directly loads or unloads the separable fixed inner cone friction wheel The pressure of the wheel (3) on the planetary gear friction wheel (2), and the contact between the planetary gear friction wheel (2) and the detachable fixed inner tapered friction wheel (3) produces friction, so that the planetary gear mechanism (II) The revolution is generated, and the revolution of the planetary gear train (II) is transmitted to the output shaft disc (5) through the planet carrier (4), and the motion and power are output by the output shaft disc (5). When the pre...

Abstract

A stepless transmission is made up of the pressure controlling device, the drive ratio controlling device, the output / input device and the planetary gear train device which has the function of the clutch and the stepless transmission. The power machine transfers the power to the taper central gear which generates the friction with the planetary gear train friction wheel to make it rotation and generate the friction with the separately fixed inner taper friction wheel to make the planetary revolution. It transfers the revolution to the output axis pan which outputs the power. The pressure controlling device controls the compress or apart of the separately fixed inner taper friction wheel to control if has the above two frictions. When no press, the drive ratio controlling device adjusts the planetary gear move along the planetary frame between the two frictions to change the effective drive diameter of the central wheel and the inner friction wheel to change the drive ratio.

Description

Technical field [0001] The invention is a universal transmission device, which can realize the continuous change of the output shaft rotation speed within a certain range under the condition of constant input rotation speed, and can also cut off and realize the transmission of motion and power at the same time. Background technique [0002] At present, the widely used mechanical continuously variable transmission adopts the transmission belt to cooperate with the driving and driven wheels with variable working diameters to transmit power. The stepless speed change within a certain range can be achieved by changing the contact diameter between the driving wheel or the driven wheel and the transmission belt. The other is to realize stepless speed change by means of friction wheels, but its disadvantage is that it is impossible to cut off movement and power. Contents of the invention [0003] The method adopted by the present invention to solve the continuously variable spee...
