Detailed description of the invention
Now in conjunction with Figure of description, describe detailed description of the invention of the present utility model in detail:
As shown be the anti-drift cardan wheel of a kind of suitcase, be made up of wheel seat 12, ball dish 2, turning rolls 8, roller 7, rotating shaft 4 cooperation, roller 7 connection is arranged on turning rolls 8 bottom, turning rolls 8 top and rotating shaft 4 normal-running fit, heavy keying fit is riveted in wheel seat 12 bottom and rotating shaft 4, the rotating shaft 4 between turning rolls 8 and wheel seat 12 is socketed the ball dish 2 arranged with rotating shaft 4 normal-running fit, wheel seat 12 top one connects the installation screw hole 1 arranging and be used for being connected and fixed with suitcase, the portion integral connection of wheel seat 12 arranges bottom disc 11, on bottom disc 11, radial symmetry arranges the upper ball orbit 13 that two upper knock hole 14 places of upper knock hole 14, two are circumferentially equipped with the upper knock hole 14 of connection two, the top one connection of turning rolls 8 arranges top disc 6, and in top disc 6, radial symmetry arranges the lower ball orbit 5 that two lower knock holees, 9, two lower knock hole 9 places are circumferentially equipped with the lower knock hole 9 of connection two, in ball dish 2, radial symmetry interlocking arranges two large balls 3, two large ball 3 places circumferentially symmetric offset spread arrange ball 10, movable interlocking is in ball dish 2 respectively at the middle part of large ball 3, ball 10, and the diameter of large ball 3 is 1.2 ~ 1.7 times of ball 10 diameter, preferably 1.25 ~ 1.45 times, described lower knock hole 9, upper knock hole 14 adopts hemispherical dome structure respectively, upper knock hole 14, the diameter of lower knock hole 9 is identical and be not more than large ball 3 diameter, large ball 3 upper, lower peripheral surface embeds knock hole 14 respectively, movable cooperation in lower knock hole 9, ball 10 upper, lower peripheral surface embeds ball orbit 13 respectively, movable cooperation in lower ball orbit 5, lower ball orbit 5, the track depth of upper ball orbit 13 is respectively to descend knock hole 9 accordingly, upper knock hole 14 progressively shoals for starting point, the most shallow position of track makes large ball 3 and lower ball orbit 5, upper ball orbit 13 forms snap-fit engagement.
For forming the snap-fit engagement of large ball 3 and lower ball orbit 5, upper ball orbit 13 better, the track width of lower ball orbit 5, upper ball orbit 13 to descend knock hole 9 accordingly, upper knock hole 14 progressively narrows for starting point, and make the track width of position, track depth the most shallow place for the narrowest, the track width at this narrowest place make large ball 3 before and after up and down four direction and lower ball orbit 5, on ball orbit 13 form snap-fit engagement respectively.
In above-described embodiment, the track depth of lower ball orbit 5, upper ball orbit 13, width respectively to descend knock hole 9 accordingly, upper knock hole 14 progressively shoals for starting point, narrows, when track is the most shallow, the narrowest position is arranged on the midway location of circumference between corresponding lower knock hole 9, upper knock hole 14, between this position and corresponding lower knock hole 9, upper knock hole 14, angle in circular segment is 90 DEG C, this situation is also that large ball 3 can the ultimate range of rolling, i.e. quadrant; The rolling distance after lower knock hole 9, upper knock hole 14 is jumped out for reducing large ball 3 further, the angle in circular segment that the most shallow for track, position, the narrowest place and corresponding lower knock hole 9, upper knock hole 14 are formed can be less than 90 °, but be generally not less than 45 °, to be formed best rolling distance when 60 ° during design.
Apply the anti-drift cardan wheel of suitcase described in the utility model, tow in process at suitcase, the position of upper knock hole 14 is changeless, lower knock hole 9 rotates with turning rolls 8, the upper of large ball 3 can be guaranteed when keeping straight on, lower peripheral surface embeds knock hole 14 respectively, movable cooperation in lower knock hole 9, on large ball 3 lower peripheral surface respectively with upper knock hole 14, lower knock hole 9 forms interlocking activity fit structure, same ball orbit 5 at present, the track depth of upper ball orbit 13 is respectively to descend knock hole 9 accordingly, upper knock hole 14 progressively shoals for starting point, make large ball 3 from lower knock hole 9, upper knock hole 14 has certain gradient to during the rolling of track centre, thus straight line tows to offset easily and tows direction, large ball 3 is jumped out and is avoided occurring that direction is departed from and drift, turn in dragging process, excessive or turn to the factors such as too quickly if there is turning power, large ball 3 may jump out knock hole 14, lower knock hole 9 is along lower ball orbit 5, the non-orbiting scroll that upper ball orbit 13 is formed, because of lower ball orbit 5, upper ball orbit 13 is respectively equipped with and makes large ball 3 and lower ball orbit 5, upper ball orbit 13 forms the position of snap-fit engagement, so large ball 3 departs from knock hole 14, along lower ball orbit 5 after lower knock hole 9, the ultimate range of the non-orbiting scroll that upper ball orbit 13 is formed is quadrant, simultaneously because lower ball orbit 5, the slope design of upper ball orbit 13, large ball 3 gravitate is returned to knock hole 14, lower knock hole 9 position, for designed by large ball 3 spacing, restrict driving, resetting structure, suitcase directly can not offset easily in towing, turn to tow in there will not be oversteer and drift, make casing can be in stabilized conditions all the time in towing.
