Abstract
A fizzing transmission viable speed device utilizes magnetic rheid (liquid) rheology character, through magnetizing to the rheid during the process of phrase changing between solid and liquid to control the distance of the two axes of the two plates then realize viable speed transmission. Power wheel could also be used to substitute the rheid.
Description
Technical field:
The invention belongs to a kind of speed changer, particularly a kind of fuzzy transmission gear shift device.
Technical background:
Existing speed changer all is mechanical transmission basically, is formed by numerous Gear combination, and the many more structures of multi-gear are also complicated more more along with the speed change gear, so speed changer also has the title of gear-box.Be divided into step change and stepless change in the mechanically operated speed changer,, need manually-operable though step change structure transmission power is big, and when high speed rotating imbalance, though stepless change is simple to operate, transmission efficiency is low, energy loss is big.Even the big power variable speed unit that utilizes hydraulic mechanism and planetary pinion combination is arranged, but its cost height, complex structure, C﹠M are not square to be made.
Summary of the invention:
The present invention is exactly the shortcoming at above-mentioned existing speed changer, and (if magnetic fluid (liquid) is when being subjected to the action of a magnetic field of a moderate strength, its apparent viscosity coefficient increases by two more than the order of magnitude to utilize the rheological property characteristic of magnetic rheological body (liquid); When magnetic rheological body (liquid) is subjected to a strong magnetic field action, will become the state of similar " solid ", the mobile disappearance.In case after removing magnetic field, becoming again can flowing liquid.This characteristic with solid, liquid and magnetic is unified in the commaterial, breeding many brand-new application), in the speed change operation, give suitable the action of a magnetic field, make magnetic rheological body (liquid) in solid-state and liquid conversion changes, realize the speed change transmission by the distance of shaft centers of two disks of control.Perhaps realize the speed change transmission by the distance of shaft centers of two disks of drive wheel control.
Description of drawings:
Accompanying drawing 1 and accompanying drawing 2 are system architecture schematic representation of present embodiment, comprising mission case 1, active disk 2, driven disk 3, magnetic field generator 4, track 5, solid-state magnetic rheological body transmission square 6, drive wheel 7 are arranged.
Embodiment:
Below the contrast accompanying drawing 1, the present invention is described in detail for accompanying drawing 2.
Initiatively the face of disk 2 and driven disk 3 is relative at first as shown in Figure 1 staggers and maintains a certain distance in the mission case 1 that is positioned over sealing, fills in mission case into magnetic rheological body (liquid).
During changed speed operation, shifting magnetic field generator 4, when magnetic field generator 4 was shifted to the axle center by the edge of driven disk 3, velocity ratio changed from small to big.Magnetic field generator 4 moves on to the axle center of the most approaching driven disk 3, and solid-state magnetic rheological body transmission square 6 is resulted near between the axle center of inferior edge of disk 2 initiatively and driven disk 3 time, velocity ratio change maximum, and the output speed of driven disk 3 is the highest.
When magnetic field generator 4 was shifted to the edge by the axle center of driven disk 3, velocity ratio from large to small.When magnetic field generator 4 moves on to the inferior edge of close driven disk 3 and aimed at the axle center of active disk, when making solid-state magnetic rheological body transmission square 6 result between the inferior edge of the axle center of disk 2 initiatively and driven disk 3, moment between two disks is zero, so velocity ratio is zero, can be considered the neutral gear of speed changer.
When magnetic field generator 4 continued to shift to the edge of driven disk 3 and cross the axle center of disk 2 initiatively, this moment, driven disk 3 was identical with turning to of disk 2 initiatively, and the output power maximum of while transmission can be considered the reverse gear of speed changer.
In like manner, replace between two disks being subjected to magnetic field to control the drive wheel 7 of the solid-state magnetic fluid transmission square 6 that forms by regulating and control in the interior different tracks of two disc axis distance, the speed change transmission that can realize bluring speed changer equally by magnetic rheological body.
In sum, the present invention has scientific and reasonable for structure, does not have mechanical wearout parts, and the life-span is long, and volume is little in light weight, is best suited for substituting the product of existing speed changer.
