Abstract
The invention discloses a kind of spherical cam steering mechanism, including chassis, spherical cam, steering fork, bearing one, spherical cam support shaft, needle bearing, guide post, bearing two, it is characterised in that：The steering fork is arranged on chassis front end by bearing one；The spherical cam support shaft has reel by needle bearing installed in steering fork lower end in the middle part of which；The spherical cam is fixedly mounted in spherical cam support shaft, and spherical cam surface is provided with annular groove；The guide post is arranged on chassis middle and lower part by bearing two, and there is guiding inserted sheet guide post front end, is oriented to inserted sheet and is inserted in the annular groove of spherical cam.The carbon-free trolley steering angle that the spherical cam steering mechanism overcomes Conventional mechanisms is less, the big problem of obstacle detouring pilespacing, it is possible to increase the steering stability of carbon-free trolley, turn to flexibly, angle big, can complete stub away from S type obstacle detouring requirements.
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 be with gravitional force drive with direction controlling function from
A kind of row dolly, it is therefore intended that carbon-free trolley of design, drives which is walked and the energy that turns to is according to energy conversion principle, by giving
Determine obtained from gravitional force conversion.The given gravitional force by unification during contest using counterweight obtaining, it is desirable to S pressed by dolly
Type track carries out advancing around stake, and wherein the pilespacing of challenge match can be with infinitely small.The carbon-free trolley of Conventional mechanisms adopts front-wheel steer
The walking manner of rear wheel drive, steering angle are less.Require to design a kind of S types challenge match dolly according to proposition, this is carbon-free little
The steering mechanism steering stability of car is high, turn to flexibly, angle big, can make dolly carry out stub away from S type obstacle detouring requirements.
Content of the invention
It is an object of the invention to provide a kind of spherical cam steering mechanism, turning for carbon-free trolley can be improved by the steering mechanism
To stability, turn to flexibly, steering angle is big, can complete stub away from S type obstacle detouring requirements.
For achieving the above object, the present invention takes technical scheme below：A kind of spherical cam steering mechanism, including chassis,
Spherical cam, steering fork, bearing one, spherical cam support shaft, needle bearing, guide post, bearing two, it is characterised in that：Described
Steering fork is arranged on chassis front end by bearing one；The spherical cam support shaft is by needle bearing under steering fork
, there is reel at end in the middle part of which；The spherical cam is fixedly mounted in spherical cam support shaft, and spherical cam surface is provided with annular
Groove；The guide post is arranged on chassis middle and lower part by bearing two, and there is guiding inserted sheet guide post front end, is oriented to inserted sheet and is inserted in ball
In the annular groove of shape cam.
Further, the spherical cam is made up of the first hemispherical cam and the second hemispherical cam.First hemispherical
Annular groove on cam is arranged symmetrically with the annular groove on the second hemispherical cam, forms the annular groove of closing.
Beneficial effects of the present invention：The spherical cam steering mechanism guides the annular groove on spherical cam by guide post
Complete the obstacle detouring requirement of carbon-free trolley.The carbon-free trolley steering angle for overcoming Conventional mechanisms is less, and obstacle detouring pilespacing is big to ask
Topic.The steering stability of carbon-free trolley can improve in the spherical cam steering mechanism, turn to flexibly, and steering angle is big, can be complete
Into stub away from S types obstacle detouring require.

Specific embodiment
Below in conjunction with the accompanying drawings, the present invention will be further described：Such as Fig. 1, shown in 2,3,4, a kind of spherical cam turns to machine
Structure, including chassis 1, spherical cam 2, steering fork 3, bearing 1, spherical cam support shaft 5, needle bearing 16, guide post 6, axle
Hold 27, it is characterised in that：The steering fork 3 is arranged on 1 front end of chassis by bearing 1；The spherical cam support shaft 5 is led to
Needle bearing 16 is crossed installed in 3 lower end of steering fork, in the middle part of which, has reel 51；The spherical cam 2 is fixedly mounted on spherical male
In wheel support shaft 5,2 surface of spherical cam is provided with annular groove 23；Under the guide post 6 is arranged in chassis 1 by bearing 27
There is guiding inserted sheet 61 in portion, 6 front end of guide post, are oriented to inserted sheet 61 and are inserted in the annular groove 23 of spherical cam 2.The spherical cam
2 are made up of the first hemispherical cam 21 and the second hemispherical cam 22.Annular groove 23 on first hemispherical cam 21 and
Annular groove 23 on two hemispherical cams 21 is arranged symmetrically, and forms the annular groove 23 of closing.
Operation principle：The gravitional force that counterweight 11 declines provides the kinetic energy of carbon-free trolley walking, and 12 one end of cotton rope is fixed on
On the reel 51 of spherical cam support shaft 5, the other end is connected with counterweight 11.Counterweight 11 declines, and drives spherical cam to support
Axle 5 is rotated, so as to drive spherical cam 2 to rotate.Spherical cam 2 is in rotation process by the guiding inserted sheet 61 on guide post 6
Guiding annular groove 23 so that spherical cam 2 completes steering-effecting during moving ahead, and then achieves carbon-free trolley obstacle detouring
Require.
The present embodiment simply to present inventive concept and the explanation that realizes, is not limited, in structure of the present invention
Under think of, the technical scheme without essence conversion is still in protection domain.
