Abstract
The utility model discloses a steering support frame of a beach vehicle, which comprises a support shaft, wherein a U-shaped support arm is arranged on the support shaft; shaft holes are respectively arranged on a left and a right arms of the U-shaped support arm; both sides of each shaft hole are movably provided with a left and a right hanging ears through rotating shafts; ear holes of the hanging ears are arranged on planes which are in parallel with the rotating shafts. When vehicle wheels and a vehicle body are in relative movement, the contact faces between friction components are large and respectively act on different components; thereby, the utility model overcomes the disadvantages of concentrate rotating components and easy friction of an old steering support frame; the movement is reliable; the stability is high; the service life is extended; the safety performance of the beach vehicle is increased. The utility model can be widely suitable for four-wheeled beach vehicles, four-wheeled electric vehicles, etc.
Description
Technical field
The utility model relates to a kind of automobile-used turning rack, particularly a kind of beach buggy turning rack.
Background technology
Along with improving constantly of living standard; the four-wheel beach buggy that various amusements are used appears in people's the life more and more; this beach buggy in use usually relative motion can occur between wheel and the car body; as the left-right rotation of wheel and the vertical tremor of car body, and such relative motion need utilize turning rack to realize and balance.The turning rack used of beach buggy generally includes in the market: the U type support arm that links to each other with the upper and lower reel cage of car body of the support shaft that links to each other with wheel, support shaft upper end, on left and right two arms of U type support arm, respectively have axis hole, there is rotating shaft to pass axis hole and bulb is set in its left and right sides, and U type support arm flexibly connects by this bulb and upper and lower reel cage, on upper and lower reel cage, be provided with the spherical shell of this bulb of parcel, when relative motion occurring between wheel and the car body, just can realize smoothly and balance by the motion between this bulb and the spherical shell; But the relative motion of wheel and car body is the left-right rotation of wheel and the vertical tremor of car body usually, there is no need to utilize the such universal transmission mechanism of bulb to realize, what is more important, because the contact surface between bulb and the spherical shell is less, the frequent relative motion of wheel and car body all can make and have friction between them, as easy as rolling off a log being worn of bulb and cause on the support arm of turning rack and the car body loosening gradually between the bottom cradle, thereby reduce service life, and bring potential safety hazard.Therefore, how overcoming these the deficiencies in the prior art, design a use needs that can satisfy beach buggy, can improve the turning rack in its service life again, is numerous customers' consistent cry.
Summary of the invention
The purpose of this utility model just is to provide a kind of like this use needs that can satisfy beach buggy, again can be wear-resistant, the turning rack that improves its service life.
The technical scheme that the utility model adopted is:
A kind of beach buggy turning rack, comprise support shaft, there is U type support arm the support shaft upper end, respectively has axis hole on left and right two arms of U type support arm, it is characterized in that: described axis hole both sides are movably installed with left and right hanger by rotating shaft, and the earhole of described hanger is arranged on the plane with shaft parallel.
As preferred version of the present utility model, above-mentioned left and right hanger all is the U type, and earhole is arranged on the both sides of U type hanger.
The beneficial effects of the utility model are: the utility model is owing to installed left and right hanger in support arm axis hole both sides by the rotating shaft activity, and when the relative car body of wheel swung, rotating shaft can be rotated in axis hole; And because the earhole of hanger is arranged on the plane with shaft parallel, the upper and lower reel cage of car body is connected with hanger by the hanger rotating shaft, and when the car body vertical tremor, upper and lower reel cage can rotate around the hanger rotating shaft; Like this, in the relative motion process of wheel and car body, contact surface between the friction means is big, and act on different parts respectively, overcome the concentrated and shortcoming easy to wear of turning rack rotating element in the past, its motion is reliable, stability is high, has prolonged service life, has improved the safety performance of beach buggy.
Description of drawings
Following accompanying drawing further specifies the utility model.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the three-dimensional broken away view of Fig. 1.
The specific embodiment
With reference to Fig. 1, Fig. 2, beach buggy turning rack of the present utility model comprises support shaft 1, there is U type support arm 11 support shaft 1 upper end, respectively have axis hole 12,13 on left and right two arms of U type support arm 11, left and right hanger 21,22 is movably arranged on the axis hole both sides by rotating shaft 6, and the earhole 7 of hanger is arranged on the plane parallel with rotating shaft 6.
In the present embodiment, rotating shaft 6 one ends are welded on the left hanger 21, and the other end passes right hanger 22 and screws with nut 4, left and right hanger 21,22 are movably arranged on axis hole 12,13 both sides of support arm; In order to guarantee that hanger rotates freely around axis hole, outside rotating shaft 6, be set with axle sleeve 3, the length of axle sleeve 3 is greater than the spacing between U type support arm axis hole 12,13 outsides; In addition, outside major axis cover 3, be with boot seal 8, can prevent that like this dust from entering axle sleeve 3 inside, more helps the service life of elongated component.
Certainly, left and right hanger 21,22 can also be movably arranged on axis hole 12,13 both sides by other modes, such as, directly replace rotating shaft with bolt, left and right hanger 21,22 is installed in axis hole 12,13 both sides respectively; And use nut locking, it also belongs to protection domain of the present utility model.
As preferred version of the present utility model, the left and right hanger 21,22 of turning rack all is the U type, and earhole 7 is arranged on the both sides of U type hanger.During use, upper and lower reel cage is movably connected between two earholes by the axle center, during the car body vertical tremor, reel cage can rotate around the axle center, and when the relative car body of wheel swings, rotating shaft 6 can be rotated in axis hole 12,13, under two kinds of relative motion states, the area of contact of the vulnerable part all bulb than original is big, and acts on respectively between the different parts, overcome the concentrated and shortcoming easy to wear of turning rack rotatable parts in the past, its motion is reliable, stability is high.
More wear-resistant in order to make between the movable parts, in the axis hole 12,13 of U type support arm, installed short sleeve 5 additional, like this, only need rebush or other vulnerable parts in the long-time back that occurs wearing and tearing of using, and do not need to change whole turning rack, prolong the service life of turning rack, also reduced maintenance cost.
