Embodiment

[0047] This embodiment provides a friction disc continuously variable transmission, which includes a first transmission element, a second transmission element and a push assembly 3 . refer to figure 1As shown, the first transmission element includes a first transmission disc 1 and a first transmission shaft 2, the first transmission disc 1 is a conical truncated circular structure, which has a conical annular slope; The end of a transmission shaft 2 is a spline structure, which is keyed to the first transmission disc 1, so that the first transmission shaft 2 can drive the first transmission disc 1 to rotate, and the first transmission disc 1 can rotate along the first transmission disc 1. Shaft 2 slides in the axial direction. The second transmission element includes a second transmission disc 4, a second transmission shaft 5 and a spring assembly 6; the second transmission disc 4 is also a conical truncated cone structure, which also has a conical annular slope The end of t...

Abstract

The invention relates to the field of stepless speed change equipment, in particular to a friction disc type stepless speed changer and a stepless speed regulation method.The stepless speed changer comprises a first transmission element, a second transmission element, a third transmission element and a fourth transmission element, the first transmission disc is in key connection with the first transmission shaft and slides in the axial direction of the first transmission shaft. The second transmission element comprises a conical second transmission disc, a second transmission shaft and a spring assembly; the conical surface of the second transmission disc abuts against the conical surface of the first transmission disc. The second transmission disc is in key connection with the second transmission shaft and slides in the axial direction of the second transmission shaft. The spring assembly abuts against the second transmission disc and has elastic potential energy enabling the second transmission disc to abut against the first transmission disc. The pushing assembly abuts against the first transmission disc, and driving force enabling the first transmission disc to abut against the second transmission disc is applied to the pushing assembly. According to the continuously variable transmission, the transmission efficiency is improved, and the transmission process is simple and reliable.

Description

technical field [0001] The invention relates to the field of stepless speed change equipment, in particular to a friction disc type stepless speed changer and a stepless speed regulating method. Background technique [0002] A continuously variable transmission is generally a transmission device used in a vehicle transmission system. The working principle of a continuously variable transmission is to realize the speed adjustment by adjusting the effective transmission radius of the active part and the driven part in the transmission device. In order to realize the adjustment of continuously variable speed, it is generally necessary to set a transition element between the driving element and the driven element for transmission. There will be sliding wear during each transmission process, and the transmission efficiency will be reduced after the secondary transmission. [0003] For example, in a common traction continuously variable transmission, the driving element and the dr...
