Abstract
The utility model relates to the field of gearboxes, and in particular relates to a stepless gearbox which comprises a gearbox body, as well as a pinion gear, wherein a bevel gear is arranged in the gearbox body, spiral gear teeth or gear races are arranged on the gear surface of the bevel gear; the pinion gear and the bevel gear are in meshing drive, the pinion gear is connected with a gear lever, and the position of the pinion gear on the gear surface of the bevel gear is changed by the gear lever. The stepless gearbox has the characteristic of being accurate and stepless in speed regulating, any speed can be regulated in the designed range. The principle of the stepless gearbox lies in that speed change can be realized according to different linear speeds caused by change of the diameters of gears coaxially from large to small. Stepless speed change can be realized through combination of the bevel gear and the pinion gear, and any speed can be regulated within the maximum ratio value range from the maximum diameter at the upper end of a spiral line to the minimum diameter.
Description
Technical field
The utility model relates to gearbox, specifically a kind of infinitely variable transmission.
Background technique
Gearbox is a kind of speed change gear that is mainly used in motor vehicle, mainly formed by gear and axle, produce variable-speed torque-converting by different Gear combination, change velocity ratio, enlarge the excursion of driving wheel torque and rotational speed, to adapt to the driving conditions of frequent variation, motor is worked under the operating mode of favourable (power is higher and oil consumption is lower).And common gearbox can only provide according to the quantity of gear fixing gear, can't realize stepless change.
The model utility content
Primary and foremost purpose of the present utility model is to provide a kind of can realize infinite variable speed infinitely variable transmission, and concrete scheme of the present utility model is as follows for achieving the above object:
A kind of infinitely variable transmission comprises casing, is provided with bevel gear in the described casing, and the wheel face of described bevel gear is provided with the spiral helicine gear teeth or race; Also comprise small gear, described small gear and described bevel gear engagement driving, described small gear is connected in a speed change lever, and described small gear changes the position of described small gear on described bevel gear wheel face by described speed change lever.
Preferably, described casing both sides are provided with chute, and the described chute direction of twice is parallel with the wheel face of described bevel gear, are provided with a slide bar by described twice chute, and described small gear is located on the described litter.
Preferably, described speed change lever is provided with fulcrum near the position of described small gear, and described fulcrum and described casing are hinged, and a connecting rod is articulated between described speed change lever and the described small gear.
The infinitely variable transmission that the utility model provides is characterized in that speed governing is accurate, and stepless speed regulation is according to being transferred to what a kind of speed in the scope of design.Its principle is that descending variation causes that the difference of linear velocity realizes speed change according to the coaxial diameter that cogs.Combination by bevel gear and small gear realizes stepless change, and what a kind of speed it can be transferred at spin line upper end maximum diameter in the maximum ratio scope between the minimum diameter of lower end.
