Embodiment Construction
[0009] As shown in Figure 1, the basic composition of the transmission device of the present invention is that on the crankshaft 9, one end of the rocker arm 23 is connected through the right connecting rod 28, and the other end of the rocking arm is connected with the overrunning clutch 24 through the left connecting rod 29, and the overrunning clutch 24 is socketed On the one-way shaft 18. An inner oil cylinder 22 , an inner slider 21 and an inner spring 30 are worn in the rocker arm 23 . A hollow governor shaft 25 radially passes through the inner slider 21 . The two ends of speed regulating shaft are connected on the slide block 19 that is positioned by oil cylinder 20 and spring 31. An oil pump 10 is coaxially connected to the end of the crankshaft 9, and the oil pump is connected to the oil cylinder at one end of the governor shaft 25 through an oil passage. In this structure, the crankshaft 9 is used as a power input shaft, and the one-way shaft 18 is used as a power ...

The invention discloses an automation variable drive. Its structure is that one end of rock arm is connected to the connecting bar on the crankshaft; the other end of the rock arm is connected to the overrunning clutch by connecting bar. The overrunning clutch is muff coupling on single direction shaft. There is oil cylinder, slide block slipper and spring tandem connected in the rock arm. A hollow speed adjust axis is directly tandem connected inside the slide block slipper. Two ends of the speed adjust axis are connected to the slider block slipper which is located by oil cylinder and spring. There is an oil pump coaxial coupling at the end of the crankshaft. The oil pump and the oil cylinder are connected with each other by oil channel. The invention could induce the margin and the lack between input power and output power, automatically adjust the varying of the length between the driving end of the rock arm and the driven end of it.
Description
technical field [0001] The invention relates to a mechanical speed change device, in particular to an automatic continuously variable speed changer. Background technique [0002] The existing continuously variable transmissions are of friction type, whose biggest disadvantages are short life and large power loss; of pulsating type, whose disadvantages are complex structure, high cost, poor working conditions at high speed and heavy load, and automatic control Not often. No. 00109979.5 patent discloses a "rolling pendulum type continuously variable transmission device". Its structure is to be provided with a rolling pendulum transmission mechanism between the input shaft and the output shaft. Devices, oscillating discs, relying on discs and cardan shafts, etc. Realize its described stepless speed change by rolling pendulum transmission mechanism. But this device and the so-called rolling pendulum transmission mechanism therein are not only relatively complicated in structu...
