Description
Technical field
The utility model belongs to a kind of motion amplification device, relates in particular to a kind ofly can make the sensitive device turning to of automobile.
Background technology
The principle of the current orthodox car steering swivel system that does not adopt hydraulic booster is: bearing circle is connected with gear by rod member, rotating of steering wheel is delivered to the gear of end, drive again the tooth bar engaging with gear to do cross motion, and the cross motion of tooth bar distance is larger, the angle that wheel turns is also larger, but in the middle of bearing circle and tooth bar, there is no corner multiplying arrangement, while making automobile turning, bearing circle need to rotate relatively large angle and just can make wheel steering, obviously sensitivity is not high, significantly steering wheel rotation of needs when particularly needing to answer sharply turning or significantly turning, operation seems very inconvenient.
Therefore, for the above-mentioned defect existing in currently available technology, be necessary to study in fact, so that a kind of scheme to be provided, solve the defect existing in prior art, between bearing circle and tooth bar, increase a corner multiplying arrangement, improve steering sensitivity, make motor turning become more sensitive, convenient.
Utility model content
For addressing the above problem, the purpose of this utility model is to provide a kind of can make the sensitive device turning to of automobile, makes motor turning become more sensitive, convenient.
For achieving the above object, the technical solution of the utility model is: a kind ofly can make the sensitive device turning to of automobile, comprise bearing circle, tooth bar and corner multiplying arrangement, described corner multiplying arrangement comprises big gear wheel, the first miniature gears group, the second miniature gears group, described bearing circle is fixedly connected with big gear wheel center by adapter shaft, described the first miniature gears group is identical with the second miniature gears group shape, include two gears, and two gear centers are fixedly connected with by axle, the first miniature gears group, the second miniature gears group is symmetrically distributed in big gear wheel both sides, described the first miniature gears group and second one of them gear of miniature gears group all engage with big gear wheel, the gear of the other end all engages with described tooth bar.
As preferably, the number of teeth of described big gear wheel be the first miniature gears group and the second miniature gears group and the big gear wheel gears in mesh number of teeth 1-2 doubly.
As preferably, described the first miniature gears group and the second miniature gears group and the big gear wheel gears in mesh number of teeth are less than and the tooth bar gears in mesh number of teeth.
As preferably, described big gear wheel, the gear that the first miniature gears group and the second miniature gears group adopt is instrument gears, modulus m≤1.5.
Compared with prior art, the utility model has following gain effect: between bearing circle and tooth bar, increase a corner multiplying arrangement, after angle enlargement bearing circle being turned over by this corner multiplying arrangement, be delivered to again on tooth bar, make the cross motion of tooth bar apart from becoming large, in having improved steering sensitivity, also make motor turning operation more convenient, simultaneously, this corner multiplying arrangement is made up of instrument gears group, and transmission is stable, and efficiency is high, reliable operation, long service life.
Brief description of the drawings
Fig. 1 is a kind of structural representation that can make the sensitive device turning to of automobile of the utility model embodiment.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
On the contrary, the utility model contain any defined by claim in marrow of the present utility model and scope, make substitute, amendment, equivalent method and scheme.Further, for the public is had a better understanding to the utility model, in below details of the present utility model being described, detailed some specific detail sections of having described.Do not have for a person skilled in the art the description of these detail sections can understand the utility model completely yet.
Referring to Fig. 1, be depicted as a kind of structural representation that can make the sensitive device turning to of automobile of the utility model embodiment, it comprises bearing circle 1, tooth bar 3 and corner multiplying arrangement 2, wherein corner multiplying arrangement 2 comprises big gear wheel 201, the first miniature gears group 202, the second miniature gears group 203, wherein the number of teeth of big gear wheel 201 be the first miniature gears group 202 and the second miniature gears group 203 with the 1-2 of the big gear wheel 201 gears in mesh numbers of teeth doubly, bearing circle 1 is fixedly connected with big gear wheel 201 centers by adapter shaft, the first miniature gears group 202 is identical with the second miniature gears group 203 shapes, include two gears, and two gear centers are fixedly connected with by axle, the first miniature gears group 202, the second miniature gears group 203 is symmetrically distributed in big gear wheel 201 both sides, described the first miniature gears group 202 and second miniature gears group 203 one of them gear all engage with big gear wheel, the gear of the other end all engages with described tooth bar 3, and the first miniature gears group 202 and the second miniature gears group 203 are less than and the tooth bar 3 gears in mesh numbers of teeth with the big gear wheel 201 gears in mesh numbers of teeth, produce a secondary amplification.
The gear that wherein big gear wheel 1, the first miniature gears group 202 and the second miniature gears group 203 adopt is instrument gears, modulus m≤1.5.
In specific works process, can make the sensitive device turning to of automobile by a kind of of above structure setting, vehicle steering turns over after certain angle, big gear wheel also turns over respective angles, big gear wheel drives the gear in the first miniature gears group and the second miniature gears group being engaged with respectively to rotate, now corner is exaggerated once, the first miniature gears group and the second miniature gears group other end with tooth bar gears in mesh also corresponding rotation, again because the first miniature gears group and the second miniature gears group and the big gear wheel gears in mesh number of teeth are less than and the tooth bar gears in mesh number of teeth, thereby produce the effect of a secondary amplification displacement of the lines, make tooth bar transverse shifting apart from becoming large, thereby increase the sensitivity while turning to.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any amendments of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
