The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
This specific embodiment is only to explanation of the present utility model; it is not to restriction of the present utility model; those skilled in the art are reading after this specification sheets and can make to the present embodiment the modification that there is no creative contribution as required, but as long as within the scope of claim of the present utility model, are all subject to the protection of patent law.
Embodiment 1: as Figure 1-4, a kind of wheel group structure that is applicable to industrial vehicle, comprises adapter plate 1 and wheels 2.
Wheels 2 comprise rotating shaft 21, are fixedly connected with wheel carrier 24 in the lower end of rotating shaft 21, are connected with wheel shaft 25 in the bottom of wheel carrier 24, and the both sides of wheel shaft 25 are respectively equipped with runner 26.
On adapter plate 1, have trepanning 11, be provided with support ring 111 at the inwall of trepanning 11, thereby trepanning 11 is divided into two parts of longitudinal distribution, in the upper part of trepanning 11, support ring 111 tops are provided with deep groove ball bearing 22; The below that rotating shaft 21 is positioned at adapter plate 1 has support end 211, between support end 211 and support ring 111, is provided with thrust ball bearing 23.
On adapter plate 1, be provided with movement parts 3, be connected between movement parts 3 and rotating shaft 21 and for by rotating shaft 21 around the rotational motion of himself axis be converted into the straight reciprocating motion of movement parts 3 bridgeware 4, can fix the locations 5 of movement parts 3 with restriction rotating shaft 21 rotational motions.
Bridgeware 4 comprises that gangbar 41, one end that one end is rotationally connected with movement parts 3 are fixedly connected on rotating shaft 21 other ends and are rotationally connected with the pivot arm 42 of STATEMENT OF FEDERALLY SPONSORED 41 other ends; The place of being rotationally connected of pivot arm 42 and STATEMENT OF FEDERALLY SPONSORED 41 deviates from the axis of rotating shaft 21 in the horizontal direction; The mode that pivot arm 42 can be screwed into rotating shaft 21 from top to bottom by screw is anchored on rotating shaft 21, and the packing ring 27 that is placed on rotating shaft 21 can be set between pivot arm 42 and the inner ring of deep groove ball bearing 22, thereby under the effect of described screw, thrust ball bearing 23 is pressed between support end 211 and support ring 111, and packing ring 27, the inner ring of deep groove ball bearing 22, pivot arm 42 threes axially fasten.
Locations 5 is oil cylinder; Movement parts 3 is a slide block, is provided with two along the symmetrical guide rail 6 of the path of motion of movement parts 3 at adapter plate 1; The opposite side of two guide rails 6 all has groove 61; The both sides of slide block also have overlaps the roller 31 that is arranged in groove 61.
When oil cylinder is failure to actuate, slide block is under the effect of rotating shaft 21, and along guide rail 6 straight reciprocating motions, now the present embodiment is cardan wheel; In the time of cylinder action, piston rod constantly stretches out, until pivot arm 42 forms straight line with gangbar 41, and make piston rod keep this state always, thereby slide block can not be moved, and now rotating shaft 21 also can not be rotated due to the effect of slide block, thereby make the present embodiment be converted to directional wheel by cardan wheel.
In this enforcement, locations 5 is also not limited only to oil cylinder, also can motor, for example, the rotational motion of motor output shaft is rotated to the straight-line motion of another part, thus can movement parts is fastening, or loose.
Movement parts 3 is also not only presented as slide block, and when locations 5 is oil cylinder, movement parts 3 can be the piston rod of oil cylinder.
Bridgeware 4 is not only also above-mentioned setting; For example, can be, on adapter plate 1, arrange and rotating shaft 21 gears in meshs, be rotationally connected a connecting rod being rotationally connected with movement parts 3 at the eccentric part of gear.
