Embodiment 1

[0025] This example figure 1 and figure 2 As shown, it is an adaptive variable speed flat disc traction type continuously variable transmission, which includes an input shaft 1, a flat disc 3, a roller 4 and an output shaft 2; it is characterized in that the input shaft 1 is a stepped shaft and passes through the frame 7 It is fixedly connected with the flat disk 3, and the flat disk 3 rotates around the axis of the input shaft 1, and a pressure spring mechanism 6 is arranged between the flat disk 3 and the input shaft 1, and the upper end of the pressure spring 6 withstands the input disk 1, The lower end bears against the frame 7, and the press spring mechanism is specifically in the form of a combined disc spring; the roller 4 is arranged at a radial position on the flat disk 3, and forms a traction drive with the flat disk 3, and can move radially along the flat disk 3; One end of the output shaft 2 passes through the threaded connection between the frame bearing seat 8 ...

Embodiment 2

[0029] This example image 3 As shown, it is an adaptive variable speed flat disc traction type continuously variable transmission, except that the flat disc 3 is an inclined conical disc type flat disc, and the other structures are the same as the first embodiment. In this embodiment, since the flat disk 3 is a slanted conical disk type flat disk, when the torque on the output shaft 2 increases and the roller 4 moves from the outer edge to the center along the radial direction of the flat disk 3, due to the structural characteristics of the inclined conical disk , will increase the compression of the spring mechanism 6 after the speed change is stable, so that the normal force between the beveled conical disc 3 and the roller 4 will increase, thereby increasing the force between the beveled conical disc 3 and the roller The traction force of the traction drive among the four is adapted to the needs of large torque transmission, and plays a role of normal force self-adaptation...

Abstract

The invention discloses a self-adaptive variable speed flat disk traction-type stepless speed regulator. The stepless speed regulator comprises an input shaft, a flat disk, a rolling wheel and an output shaft, and is characterized in that the input shaft penetrates through a machine frame to be fixedly connected with the flat disk; the flat disk rotates around the axis of the input shaft; a pressure spring mechanism is arranged between the flat disk and the input shaft; one end of the pressure spring mechanism is connected to the machine frame, and the other end of the pressure spring mechanism is connected to one end of the flat disk; the rolling wheel is arranged in the radial position of the flat disk; the rolling wheel and the flat disk form traction drive; the rolling wheel can radially move along the flat disk; one end of the output shaft is provided with an external thread, and the rolling wheel is provided with an internal thread; the external thread of the output shaft and the internal thread of the rolling wheel form threaded connection so that the rolling wheel can rotate around the axis of the output shaft; and the other end of the rolling wheel is connected with one end of a balance spring mechanism, and the other end of the balance spring mechanism is connected to the machine frame. By adopting the stepless speed regulator, self-adaptive speed changing to change of torque of the output shaft can be realized. The stepless speed regulator is simple in structure, convenient to control and easy to realize.

Description

technical field [0001] The invention relates to the field of traction continuously variable transmissions, in particular to an adaptive variable speed flat disk traction continuously variable transmission. Background technique [0002] Continuously variable transmission (CVT) is an ideal mechanical transmission solution, because the CVT can provide a series of continuous transmission ratios so that the vehicle engine is always at a high-efficiency point, which greatly improves the efficiency of the vehicle and reduces the Vehicle emissions, to achieve the role of energy saving and emission reduction. According to statistics, cars using continuously variable transmissions can save fuel by 7%-15% compared with cars using automatic transmissions (AT), reduce exhaust emissions by about 10%, and reduce production costs by 20%-30%. A hybrid vehicle with a continuously variable transmission drive train can reduce fuel consumption by 30% and reduce emissions by 45%. Continuously v...
