Abstract
The utility model discloses a speed changer for vehicle. In order to overcome the low non-uniform velocity adjusting accuracy of the existing automobile non-uniform velocity mechanism and the technique insufficiency in the components knock wear-out aspect, the utility model speed changer for vehicle adopts the speed governing technique facility of altering the axle key position to select the change pulley group with different velocity ratios, so the non-uniform velocity function is realized. The utility model has the technique characteristics of easy of adjusting, convenient and flexible non-uniform velocity operation, small knock wear-out between the components and long service life.
Description
Technical field
The utility model relates to the mechanical speed change technical field of speed change conversion on the vehicles such as being installed on bicycle, three-wheel vehicle or Electrical Bicycle.
Background technology
Above-mentioned all kinds vehicle, the transmission system that extensively adopts installation is arranged at the trailing wheel place, and command range is long, complex structure, causes speed ratio conversion difficulty and inconvenient, brings many inconvenience for installation and maintenance.Chinese patent: name is called " derailleur ", the patent No. is the disclosed technical scheme of CN94223828.1, between axle drive shaft and output shaft, be provided with the switching mechanism that is used to regulate the conversion speed ratio of forming a connecting link, constituting by the transmission of variable shaft and this slip setting connection wheel in this technical scheme, by the direct hand adjustment transmission connection of shift fork wheel location.This type of directly goes up the structure formation that the position reaches speed changing function by the axle that changes between the transmission connection wheels, the major technique disadvantage that exists is frequently to change transmission connection wheel transmission position, the transmission position accurately to guaranteeing just between power wheel, the hard switching process that directly changes the power wheel position in addition makes the mechanical wear between the driving wheel group very big, has influenced the service life of this mechanism.So existing technology is not perfect.
The utility model content
For overcoming the technical deficiency that aspects such as accuracy that existing vehicle speed variation mechanism adjusts in speed change and components hit wearing and tearing exist, the technical scheme of the disclosed a kind of automobile-used transmission system of the utility model.
The variable shaft of the automobile-used transmission system of the technical program is installed to be arranged between car axis and the car body axle drive shaft and is in transmission connection, variable shaft and car body drive and supportingly on the axis body are provided with the speed change wheels that some formation transmission speed ratios are different and transmission position is fixing, the change wheel on the variable shaft and the diameter of axle are to freely rotating setting, slide in the axial slide of variable shaft and be provided with change wheel shaft alignment feather key, each change wheel axis hole edge on the variable shaft is provided with and the cooresponding seam groove of this shaft alignment feather key, and the axial location of adjusting shaft location feather key is provided with manual driving lever.
The disclosed automobile-used transmission system technical scheme of the utility model, be by the relevant position of shifting axle location feather key at variable shaft, coming to go up corresponding change wheel with axle, to give axle fixing, reach required variable speed drive (VSD) conversion, because the speed change wheels transmission position of present technique is put fixing, the speed governing form that has replaced original direct change speed change wheels position by the mode of speed control of feather key position on the shifting axle, realized the control action of " art is good for strength ", be easy to regulate so present technique has, variable speed operation is convenient and flexible, brinelling between the parts is little, the technical characterstic of long service life.
Below in conjunction with shown in accompanying drawing specifically implement structure and describe technology contents of the present utility model in detail.
Description of drawings
Fig. 1 is the sectional structure chart of the automobile-used transmission system of the utility model
Fig. 2 is that the A-A of Fig. 1 is to sectional structure chart.
The specific embodiment
As shown in the figure, the automobile-used transmission system of the utility model is installed and is arranged between car dynamical axis and the live axle, so-called car dynamical axis can be bicycle, three-wheel vehicle footboard drives axis, it also can be the motor output shaft of Electrical Bicycle, in the present embodiment, be that example describes with the bicycle.This automobile-used transmission system is provided with transmission and is arranged at variable shaft 2 and auxiliary variable speed axle 3 between axis 1 and the bicycle rear shaft 4, variable shaft 2 and auxiliary variable speed axle 3 are provided with speed change wheels I, II, the III transmission of some assembly covers, that realize different transmission velocity ratios, wherein are arranged at radially turning fit of the change wheel of variable shaft 2 and variable shaft.For can driving corresponding speed change wheels, the related rotation that makes variable shaft 2 drives hind axle 4 with transmission, in the axial slide of variable shaft 2, be provided with and be used for coming chosen axis to fix the shaft alignment feather key 21 of each change wheel with the key fixed form, this concrete enforcement in the structure, in order to strengthen the mechanical strength of shaft alignment feather key, promptly strengthen the plane of action of shaft alignment feather key 21 and each change wheel, this feather key 21 is a skateboard structure, its slide plate both sides are provided with the key pin 26 that protrudes from variable shaft, the cooresponding seam groove in this key pin 26 and change wheel axis hole edge 25 is corresponding, the axle of realizing change wheel is fixing, this slide type feather key 21 is arranged to slide in the axial penetrating chute 24 of variable shaft and is provided with, penetrating chute 24 is made the back and is lacked 22 by two side shafts, 23 fold formation, for ease of selecting to change the axial location of this shaft alignment feather key 21, shaft alignment feather key 21 is fixed as one with the thumb wheel 20 that is arranged on the variable shaft 2 that slides, and changes its relative position on variable shaft by manual driving lever 28.Casehistory, if manually driving lever 28 moves thumb wheel 20, with axle fixedly feather key 21 be transferred to change wheel I position with this speed change wheel shaft fixing after, axis 1 power wheel drives variable shaft 2 and speed change wheels I, auxiliary variable speed axle 3 and its power wheel, the operation of drive back wheels of vehicle, when axle when fixedly feather key 21 changes its choice of location with speed change wheels II, III axle heavy keying fit, promptly changed the transmission speed of axis 1, the realization speed changing function with back wheels of vehicle.In present technique, between its speed change wheels, the power wheel except that adopting the gear transmission, can also adopt the drive mechanism of sprocket wheel, if the speed change wheels are to realize transmission with the chain gear structure, promptly strengthened the transmission distance between variable shaft and the auxiliary variable speed axle, then can be by auxiliary variable speed axle 3 as hind axle, the operation of direct drive trailing wheel.
