Abstract
The utility model discloses a bracket wheel, which comprises a tyre, a wheel shaft, a movable frame, a fixed frame and an actuating mechanism, wherein the movable frame is connected on the wheel shaft, the actuating mechanism is used for actuating the bracket wheel, and a driving mechanism used for driving the fixed frame to do the extending and retracting movement is arranged on the movable frame. Both sides of the bottom of an outer pipe of the bracket wheel are correspondingly provided with U-shaped elongated slots, wheel supporting plates are completely inserted into the U-shaped elongatedslots when the bracket wheel is folded, the fixed frame and the movable frame are interlocked to realize the effect on preventing the movable frame of the bracket wheel from being disengaged when motor vehicles run, and the structure is stable. After the fixed frame of the bracket wheel is prolonged, the bracket wheel can drive a tractor to rotate in each direction. A ladder type leading screw ismatched with a nut to realize the effect of height regulation, a thrust bearing structure is adopted at the top end, and the utility model has the advantages of labor saving of regulation, heavy loadand long service life.
Description
Technical field
The utility model relates to a kind of rack wheel, relates in particular to the rack wheel that uses on a kind of trailer.
Background technology
But one of main pattern of conveying objects is to utilize power actuated vehicle pulling trailer.When breaking away from truck, trailer need connect the parts rack wheel that supports trailer.When trailer was attached to truck, support drew in fully; When rack wheel transfer contact to earth firmly after, can separate with trailer by power actuated vehicle, rack wheel was both played a supporting role on trailer, played the effect of castor again when trailer moves.Similar rack wheel is arranged in the market, but all have structural instability, can not drive trailer and rotate, regulate effort, shortcoming such as bearing capacity little and service life is low to all directions.
Summary of the invention
At the deficiencies in the prior art, technical problem to be solved in the utility model is, a kind of Stability Analysis of Structures is provided, and can drive trailer and rotate to all directions, regulate laborsaving, the rack wheel of the big and long service life of bearing capacity.
For solveing the technical problem, technical solution adopted in the utility model is: a kind of rack wheel, comprise tire, wheel shaft, be connected tressel, the fixed mount on the wheel shaft and be used for the driver train that driving arm is taken turns, be provided for driving the lead agency that fixed mount is done elongation and shortened motion on the described tressel.
Above-mentioned rack wheel, described fixed mount is provided with an outer tube, and described outer tube bottom is a U-shaped elongated slot planform; Described tressel is provided with pipe and wheel stay bearing plate in one.
Above-mentioned rack wheel, described lead agency are the leading screw screw structures that is made of leading screw and nut.
Above-mentioned rack wheel, the outer end that described leading screw combines with lead agency are provided with supporting spring, pad, handgrip and handwheel under supporting spring on the bearing, bearing, the bearing; Be connected with spring pin between described leading screw and the handgrip.
The corresponding processing of the two bottom sides of the utility model outer tube U type elongated slot draws the hour wheel stay bearing plate at rack wheel and should insert fully in the U type elongated slot, and fixed mount and tressel interlocking prevent when playing movement of vehicle that the rack wheel tressel from coming off Stability Analysis of Structures.After the fixed mount of rack wheel prolonged, rack wheel can drive trailer and rotate to all directions.Trapezoidal screw cooperates the effect of regulating height that reaches with nut, thrust bearing is adopted on the top, realizes that adjusting is laborsaving and carrying is big and high life.
Description of drawings
Fig. 1 is the front view of the utility model rack wheel;
Fig. 2 is the front view of tressel;
Fig. 3 is the cutaway view of the utility model fixed mount.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
As Fig. 1, this rack wheel comprises tire 4, wheel shaft 3, is connected tressel 1, the fixed mount 2 on the wheel shaft and is used for the driver train that driving arm is taken turns, and is provided for driving the lead agency that fixed mount 2 is done elongation and shortened motion on the tressel 1.Fixed mount is provided with an outer tube 14, and the outer tube bottom is a U-shaped elongated slot planform; Tressel is provided with pipe 6 and wheel stay bearing plate 5 in one.Lead agency is the leading screw screw structure that is made of leading screw 15 and nut 7.The outer end that leading screw 15 combines with lead agency is provided with supporting spring 13, pad 11, handgrip 9 and handwheel 8 under supporting spring 12 on the bearing, bearing 16, the bearing; Be connected with spring pin 10 between leading screw 15 and the handgrip 9.
During use, by attaching parts rack wheel is fixed on the trailer, before power actuated vehicle drives the trailer motion, at first should rotate handgrip, tressel is drawn in fully, when the power actuated vehicle parking need be unloaded trailer, should rotate after handgrip transfers tressel to contact to earth firmly, can separate with trailer by power actuated vehicle, rack wheel was both played a supporting role on trailer, played the effect of castor again when trailer moves.Rotate flexibly between these product requirement parts, can bear certain load, reliable and stable, long service life.
Claims (4)
1, a kind of rack wheel comprises tire, wheel shaft, is connected tressel, the fixed mount on the wheel shaft and is used for the driver train that driving arm is taken turns, and it is characterized in that: be provided for driving the lead agency that fixed mount is done elongation and shortened motion on the described tressel.
2, rack wheel according to claim 1 is characterized in that: described fixed mount is provided with an outer tube, and described outer tube bottom is a U-shaped elongated slot planform; Described tressel is provided with pipe and wheel stay bearing plate in one.
