Abstract
The invention relates to a carbon-free trolley steering gear, a fine adjustment long rod is connected with a cross rod through a fine adjustment nut, the cross rod is fixed on a front wheel support, the fine adjustment nut, the fine adjustment long rod, a rotational nut and the cross rod constitute a crank connecting link displacement fine adjustment system, the carbon-free trolley steering gear adopts a crank connecting link mechanism so as to realize trolley steering fine adjustment, by changing the relative positions of the fine adjustment nut and a fine adjustment crank rotation center shaft, the position of the fine adjustment nut, which is on the fine adjustment long rod, realizes the obstacle crossing requirement for different intervals within 700 millimeters to 1300 millimeters, as the crank connecting link mechanism does not have a sliding pair of a sine mechanism, the energy consumption caused by friction is reduced greatly, simultaneously, the precision prescribed is relatively lowered, and thus batch production can be realized.
Description
Technical field
The present invention relates to a kind of steering hardware, particularly relate to a kind of carbon-free trolley steering hardware.
Background technology
Carbon-free trolley manufactures and designs under the background based on the contest of national college students' engineering training integration capability, the product on basis is trained for mechanical speciality Students ' Engineering, the requirement of the carbon-free trolley of national college students' engineering training integration capability contest is a kind of three wheeler of design, require that dolly has course changing control mechanism, and this course changing control mechanism has adjustable function, to adapt to the competition venue being placed with different spacing obstacle, therefore, steering hardware is the key during carbon-free trolley designs and produces, the carbon-free trolley of taking part in game at present adopts sine mechanism more, can not realize producing in enormous quantities and application, there is no practical popularization significance.
Summary of the invention
The object of the present invention is to provide a kind of carbon-free trolley steering hardware, solve in the carbon-free trolley of taking part in game at present and adopt sine mechanism more, can not realize producing in enormous quantities and application, there is no the problem of practical popularization significance.
The present invention realizes like this, it comprises fine-tuning nut, fine setting stock, rotating nut, cross bar, it is characterized in that: described fine setting crank is fixed on finishing bevel gear cuter flower wheel, described fine-tuning nut connects fine setting crank and fine setting stock, described fine setting stock is connected with cross bar by fine-tuning nut, described cross bar is fixed on front-wheel support, and described fine-tuning nut, fine setting stock, rotating nut and cross bar form crank connecting link displacement micro-tensioning system.
Described fine setting crank is connected with fine-tuning nut revolute pair.
Described fine-tuning nut is connected with fine setting stock revolute pair.
Technique effect of the present invention is: the present invention adopts piston crank mechanism to realize dolly and turns to fine setting, by changing fine-tuning nut and the relative position of finely tuning Brace Turning Center axle, the position of fine-tuning nut on fine setting stock realizes the obstacle detouring requirement within different spacing 700mm-1300mm, because piston crank mechanism does not have the moving sets of sine mechanism, greatly reduce friction energy-dissipating, precision prescribed reduces relatively simultaneously, makes can manufacture.

In the drawings, 1, stepped appearance under-carriage 2, axle drive shaft 3, finishing bevel gear cuter driving wheel 4, finishing bevel gear cuter flower wheel 5, fine setting crank 6, fine-tuning nut 7, fine setting stock 8, rotating nut 9, cross bar 10, front-wheel support 11, front-wheel 12, fixed pulley 13, fixed pulley support 14, driven rear wheel 15, drive trailing wheel 16, potential energy mass.
Detailed description of the invention
Composition graphs 1,2,3,4,5 illustrates the present invention, described fine setting crank is fixed on finishing bevel gear cuter flower wheel, described fine-tuning nut connects fine setting crank and fine setting stock, described fine setting stock is connected with cross bar by fine-tuning nut, described cross bar is fixed on front-wheel support, and described fine-tuning nut, fine setting stock, rotating nut and cross bar form crank connecting link displacement micro-tensioning system.
During use, because potential energy mass 16 is connected with axle drive shaft 2 by cotton rope, fixed pulley 12 walked around by cotton rope, potential energy mass 16 rises until can falling head be 400 ± 2mm gradually, dolly power is ready to complete, before carbon-free trolley is put into starting line, make Trolley front wheel concordant with starting line, according to run obstacle spacing adjustment crank and stock length, angle needed for vehicle body and shimmy of front wheels angle when setting out, decontrol dolly, potential energy mass 16 starts to fall, axle drive shaft 2 rotates thereupon, rear wheel is driven to make dolly automatic running forward, meanwhile finishing bevel gear cuter driving wheel 3 rotates along with axle drive shaft 2, band dynamic bevel gear flower wheel 4 rotates, fine setting crank 5 rotates together, drive fine setting stock 7, cross bar 9 and front-wheel 11 make periodic wobble, thus dolly will complete the walking of serpentine obstacle detouring according to the circuit of design, when obstacle distance changes, the position of adjustment fine-tuning nut 6 on fine setting crank 5 and fine setting stock 7, the relative length of nut and crank rotary middle spindle is changed, the length that stock swings changes, thus change pivot angle size and the time of oscillation of front-wheel, complete displacement serpentine obstacle detouring to walk around stake.
