Abstract
The invention discloses a steering mechanism for a spherical cam. The steering mechanism comprises a bottom disc, the spherical cam, a steering yoke, a first bearing, a support shaft of the spherical cam, a needle roller bearing, a guide rod and a second bearing and is characterized in that the steering yoke is mounted at the front end of the bottom disc by means of the first bearing; the support shaft of the spherical cam is arranged at the lower end of the steering yoke by means of the needle roller bearing and provided with a winding wheel; the spherical cam is fixedly installed onto the support shaft of the spherical cam; the surface of the spherical cam is provided with an annular groove; the guide rod is mounted at the middle-lower portion of the bottom disc by means of the second bearing; and the front end of the guide rod is provided with a guide inserting piece inserted into the annular groove of the spherical cam. The steering mechanism for the spherical cam has following beneficial effects: problems of a conventional mechanism such as small steering angles and great obstacle-surmounting pile distance of a carbon-free car are overcome in order to improve steering stability of the carbon-free car; and the car steers flexibly at great angle and capable of finishing the S-shaped obstacle-surmounting operation of a short pile distance.
Description
Technical field
The present invention relates to a kind of walking steering mechanism, in particular to a kind of spherical cam steering mechanism.
Background technology
College Students ' Engineering training integrated ability contest proposition is the automatic carriage with direction controlling function driven with gravitional force, object is to design a kind of carbon-free trolley, the energy driving it to walk and to turn to is according to energy conversion principle, is obtained by given gravitional force conversion.This given gravitional force is obtained by the counterweight used unified during contest, and require that dolly is undertaken advancing around stake by S type track, the pilespacing of wherein challenge match can be infinitely small.The carbon-free trolley of Conventional mechanisms adopts the walking manner of front-wheel steer rear wheel drive, and steering angle is less.Require to design a kind of S type challenge match dolly according to proposition, steering mechanism's steering stability of this carbon-free trolley is high, turns to flexibly, angle is large, dolly can be made to carry out the S type obstacle detouring requirement of stub distance.
Summary of the invention
The object of this invention is to provide a kind of spherical cam steering mechanism, the steering stability of carbon-free trolley can improve in this steering mechanism, and turn to flexibly, steering angle is large, can complete the S type obstacle detouring requirement of stub distance.
For achieving the above object, the present invention takes following technical scheme: a kind of spherical cam steering mechanism, comprise chassis, spherical cam, steering fork, bearing one, spherical cam back shaft, needle bearing, guide post, bearing two, it is characterized in that: described steering fork is arranged on chassis front end by bearing one; Described spherical cam back shaft is arranged on steering fork lower end by needle bearing, has reel in the middle part of it; Described spherical cam is fixedly mounted on spherical cam back shaft, and spherical cam surface has annular groove; Described guide post is arranged on middle and lower part, chassis by bearing two, and there is guiding inserted sheet guide post front end, and guiding inserted sheet is inserted in the annular groove of spherical cam.
Further, described spherical cam is made up of the first hemispherical cam and the second hemispherical cam.Annular groove on annular groove on first hemispherical cam and the second hemispherical cam is arranged symmetrically with, and forms the annular groove closed.
Beneficial effect of the present invention: this spherical cam steering mechanism completes the obstacle detouring requirement of carbon-free trolley by the annular groove on guide post guiding spherical cam.The carbon-free trolley steering angle overcoming Conventional mechanisms is less, the problem that obstacle detouring pilespacing is large.The steering stability of carbon-free trolley can improve in this spherical cam steering mechanism, and turn to flexibly, steering angle is large, can complete the S type obstacle detouring requirement of stub distance.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be further described: as Fig. 1,2,3, shown in 4, a kind of spherical cam steering mechanism, comprises chassis 1, spherical cam 2, steering fork 3, bearing 1, spherical cam back shaft 5, needle bearing 16, guide post 6, bearing 27, it is characterized in that: described steering fork 3 is arranged on front end, chassis 1 by bearing 1; Described spherical cam back shaft 5 is arranged on steering fork 3 lower end by needle bearing 16, has reel 51 in the middle part of it; Described spherical cam 2 is fixedly mounted on spherical cam back shaft 5, and spherical cam 2 surface has annular groove 23; Described guide post 6 is arranged on middle and lower part, chassis 1 by bearing 27, and there is guiding inserted sheet 61 guide post 6 front end, and guiding inserted sheet 61 is inserted in the annular groove 23 of spherical cam 2.Described spherical cam 2 is made up of the first hemispherical cam 21 and the second hemispherical cam 22.Annular groove 23 on first hemispherical cam 21 and the annular groove 23 on the second hemispherical cam 21 are arranged symmetrically with, and form the annular groove 23 closed.
Operation principle: the kinetic energy that the gravitional force that counterweight 11 declines provides carbon-free trolley to walk, cotton rope 12 one end is fixed on the reel 51 of spherical cam back shaft 5, and the other end is connected with counterweight 11.Counterweight 11 declines, and drives spherical cam support axle 5 to rotate, thus drives spherical cam 2 to rotate.Spherical cam 2 by the guiding inserted sheet 61 guide ring connected in star 23 on guide post 6, makes spherical cam 2 complete steering-effecting in the process of moving ahead, and then achieves the requirement of carbon-free trolley obstacle detouring in rotation process.
The present embodiment just to the present invention's design and explanations realizing, is not limited, and under the present invention's design, the technical scheme converted without essence is still in protection domain.
