The specific embodiment
Below in conjunction with drawings and Examples the utility model is described further.Though the utility model will be described in conjunction with preferred embodiment, should know, do not represent that the utility model is limited among the described embodiment.On the contrary, the utility model will be contained alternative, modified and the equivalent in the scope of the present utility model that can be included in attached claims restriction.
As shown in Figure 1 to Figure 3, this carbon-free dolly direction-control apparatus that uses differential mechanism that is applicable to, main by the edge cam 1 that is produced on the driving wheel end face, with the supporting slide bearing assembly 2 of cam path, push rod 3, linear bearing 4, linear axis bearing 5, slide bearing assembly constraint mechanism 13, be installed in the adjusting slider 6 of push rod end, adjusting slider hold-down screw 7, abut against the fine-tuning nut 8 of adjusting slider the inner, orbital radius adjusting rod 9, radius adjusting rod hold-down nut 10, the direction rocking bar 11 and the direction rocking bar that are installed on the front-wheel support 23 are stirred compositions such as assembly 12.Push rod 3 fixes its direction of motion by linear bearing 4 and its bearing block 5, and the power of its motion is provided by cam path and the slide bearing assembly 2 supporting with it, and it can be seesawed according to the variation of cam path radius.Its front end is equipped with an adjusting slider 6, and adjusting slider 6 and push rod 3 realizes being tightly fixed installations, and a section of contacting with the slide block end face of push rod 3 is manufactured with adjusting screw thread 14, is furnished with fine-tuning nut 8 on the adjusting screw thread.Be with the holder 15 of orbital radius adjusting rod 9 on the adjusting slider 6, fix by adjusting slider hold-down screw 7 between holder 15 and the slide block 6.The front end that slide block 6 cooperates with holder 15 leaves the 3-5 mm clearance, with the convenient front and back position of regulating holder by fine-tuning nut 8.And holder 15 is equipped with perpendicular orbital radius adjusting rod 9 at horizontal plane, orbital radius adjusting rod 9 by former and later two radius adjusting rod hold-down nuts 10 regulate its length of stretching out and and holder 15 between fixing.Orbital radius adjusting rod 9 is equipped with the direction rocking bar in the direction perpendicular to horizontal plane and stirs assembly 12, and the direction rocking bar is stirred assembly 12 lower ends ball bearing 16 is installed, and himself fixes by two locknuts 17 up and down.The ball bearing 16 that the direction rocking bar is stirred assembly 12 lower ends matches with the chute of direction rocking bar 11 on being installed in front-wheel support 23, and when push rod 3 seesawed, pushing direction rocking bar 11 was realized turning to.Edge cam 1 is that the form with cam path presents, with the supporting slide bearing assembly 2 of its cam path cooperating by sliding bearing 18 and cam path, the change in radius of edge cam 1 is reflected on the push rod 3, make push rod 3 rectilinear motion forward or backward, push rod 3 drives orbital radius adjusting rod 9 again and stirs direction rocking bar 11, makes front-wheel 22 realize turning to.Formed by dead man 19, direction constrain bearing 20, sliding bearing 18 with the slide bearing assembly 2 that cam path is supporting, dead man 19 is axial perpendicular to push rod 3, be parallel to horizontal plane, be installed in the rear portion of push rod 3 by the center of circle of push rod 3, fixing by the screw 21 of its afterbody.Direction constrain bearing 20 is stuck in the straight trough of slide bearing assembly constraint mechanism 13, makes push rod 3 and remains on the plane parallel to the ground with the supporting slide bearing assembly 2 of cam path.
Its function of the utility model mainly comprises and turns to the benchmark adjustment and turn to control two parts.When requiring dolly to press the desired trajectory walking, though toward which direction change by edge cam 1 control, the size that turns to is controlled by the length that orbital radius adjusting rod 9 stretches out, turn to accurately but make, at first must determine with linear movement direction as benchmark, otherwise when turning to when controlling, will inevitably turn in one direction, and on another direction understeer, cause the dolly depart.
Here the adjusting of reference direction is realized by the micro-adjusting mechanism that fine-tuning nut 8, adjusting slider 6 and orbital radius adjusting rod holder 15 are formed.When dolly needed straight line to move ahead, front-wheel 22 must be over against the dead ahead, and direction rocking bar 11 is on the position vertical with front-wheel 22 wheel faces.If deviation is arranged slightly, will influence the accuracy of direction control.This time, if by test, find that dolly is toward left avertence, after direction rocking bar 11 positions are inclined to one side, can unclamp the adjusting slider hold-down screw 7 on the orbital radius adjusting rod holder 15, unclamp fine-tuning nut 8 then, loosening amount is according to turning to the amount of skew to decide, promote orbital radius adjusting rod holder 15 mobile some distances backward then, to realize the purpose of correction, if find to have adjusted excessive or also adjusted not in placely by test, then adjusted according to bias again, till accurately next time.Owing to be provided with fine-tuning nut 8, adjustment amount can be controlled by the rotation number of degrees of fine-tuning nut 8, is unlikely to blindly to adjust, and by just adjusting to the right place several times, straight-line benchmark adjustment is accurate, lays a solid foundation just for the accurate adjustment of direction.
Be the control that turns to size again, by the change of shape of edge cam 1, push rod 3 seesawed, drive orbital radius adjusting rod 9 and direction rocking bar are stirred assembly 12 and are seesawed, rotate forward or backward thereby drive direction rocking bar 11, steering wheel is also rotated front and back, realize turning to.And the size that turns to is regulated by the length that orbital radius adjusting rod 9 stretches out, and this bar stretches out length, push rod 3 walk same apart from the time, the radius that turns to is just big, otherwise and, the radius that turns to is just little.Like this, control turning to of dolly by the shape of edge cam 1, and regulate the size that turns to by the length that orbital radius adjusting rod 9 stretches out, require to realize direction control accurately according to predetermined turning to.
