Description
Affiliated technical field
The utility model relates to a kind of pulse-type continuously variable transmission, especially a kind of low pulse degree pulse-type continuously variable transmission.
Background technique
Pulsation degree and impulsive load are the focuses of mechanical stepless transmission research always, the GUSA-II type pulse-type continuously variable transmission of present function admirable, and the pulsation degree minimum during work is 5%, is up to about 30%; The pulsation generating mechanism utilizes quickreturn characteristics to reduce degree of pulsation, has big acceleration and noise in backhaul.On the stepless change device of pulsed, the pulse-type continuously variable transmission production of China arises from the beginning of the seventies, the product of the fifties in Germany is copied in main mapping, and the specification kind is few, (up 35% during work), power less (peak output is 7.5Kw in the market), structural type are single greatly for pulsation degree.
The model utility content
In order to address the above problem, the utility model provides a kind of low pulse degree pulse-type continuously variable transmission, and it not only can realize pulsed stepless change output, and pulsation degree is low, vibration and noise is little, speed change is stablized, performance is good.
The technical solution of the utility model is to constitute like this, it is characterized in that: it comprises input cam, acts on the roller of input cam working surface, in order to guarantee pressurizing mechanism that roller closely contacts with the input cam working surface all the time, be articulated in output rocking bar on the power output revolving shaft, be articulated in connecting rod between roller and the output rocking bar swinging end, kink on connecting rod slide block and in order to feed screw nut's speed regulating mechanism of control slide block, the slide output terminal and the slide block of described feed screw nut's speed regulating mechanism are hinged.
During work, guarantee that by pressurizing mechanism the roller on the connecting rod closely contacts with the working surface of input cam; When input cam rotates, drive output rocking bar swing several angle by roller and connecting rod, utilize three-phase structure, realize the pulsation output of output rocking bar; Utilize feed screw nut's speed regulating mechanism to come the diverse location of continuous control slide block in phase place, can continuously change the amplitude of fluctuation of output rocking bar, thereby realize stepless change.In addition, by the appropriate design cam profile, can realize that also the pulsation degree is zero under the condition of specific speed governing position (velocity ratio); Carry out parameter designing, virtual emulation analysis by CAD, CAE software, impulsive load is little in the time of can making its running, gearshift performance stable, the moving degree of clockwise and anticlockwise work time pulse is constant.
GUSA-II type pulse-type continuously variable transmission than present function admirable, the utility model is not only simple in structure, volume is little, and realizing under the high bearing capacity condition having pulsation degree low (can realize that degree of pulsation is zero), vibration and noise is little, speed change stable, performance is good, the clockwise and anticlockwise work time pulse is moving spends advantages such as constant.
