Abstract
The invention discloses a steering axle of a transport cart. The steering axle of the transport cart comprises an axle body, a first hydraulic cylinder and a second hydraulic cylinder, wherein the left and right ends of the axle body are respectively provided with a first steering knuckle and a second steering knuckle; the first steering knuckle is rotationally connected with the left end of the axle body via a first plane bearing; the second steering knuckle is rotationally connected with the right end of the axle body via a second plane bearing; the first hydraulic cylinder and the second hydraulic cylinder are symmetrically arranged on the axle body; one end of the first hydraulic cylinder is movably connected with the axle body, and the other end of the first hydraulic cylinder is movably connected with the first steering knuckle; one end of the second hydraulic cylinder is movably connected with the axle body, and the other end of the second hydraulic cylinder is movably connected with the second steering knuckle. The steering knuckles of the steering axle are rotationally connected with the axle body via the plane bearings, so that the resistance of the steering axle in steering is reduced, and is only one tenth of the original resistance.
Description
Technical field
The present invention relates to steeraxle technical field, be specifically related to a kind of steeraxle of transport trolley, particularly the steeraxle of beam transportation vehicle.
Background technology
Bridge transport vehicle is usually used in railway construction and carries out bridge transportation.The general tonnage of bridge is all larger, and this just requires that transport trolley has extraordinary load-carrying, will have good steering flexibility simultaneously.Bridge transport vehicle load-carrying travels gently on rough road, and some places road surface is not very wide, and this just has better requirement to the front steering axle of bridge transport vehicle.It is large to there is resistance in existing steeraxle when turning to, the problem that service life is short.
Summary of the invention
In order to solve existing steeraxle, to there is resistance large, the problem that service life is short, the present invention proposes a kind of steeraxle of transport trolley, and steering swivel and the pontic of this steeraxle are rotationally connected by surface bearing, decrease resistance when steeraxle turns to, resistance only has 1/10th of original resistance.
Technical scheme of the present invention is achieved in that
A kind of steeraxle of transport trolley, comprise pontic, the first hydraulic actuating cylinder and the second hydraulic actuating cylinder, the two ends, left and right of described pontic are separately installed with the first steering swivel and the second steering swivel, described first steering swivel is rotationally connected by the left end of the first surface bearing and described pontic, and described second steering swivel is rotationally connected by the right-hand member of the second surface bearing and described pontic; Described first hydraulic actuating cylinder and described second hydraulic actuating cylinder are symmetricly set on above described pontic, described first hydraulic actuating cylinder one end is flexibly connected with described pontic, its other end is flexibly connected with described first steering swivel, described second hydraulic actuating cylinder one end is flexibly connected with described pontic, and its other end is flexibly connected with described second steering swivel.
Further, be provided with the first lining in described first steering swivel, described first lining is enclosed within above described first surface bearing, is provided with the second lining in described second steering swivel, and described second lining is enclosed within above described second surface bearing.
Further, described first steering swivel is identical with the structure of described second steering swivel, described first steering swivel comprises track arm and front spindle nose, described track arm one end is welded with the first end of described front axle, the nearly weld of described front axle head rest is provided with the first through hole, described first through hole is installed for described first surface bearing, and described track arm is curved, and described track arm and described front spindle nose are obtuse angle away from the angle of described weld one end.
Beneficial effect of the present invention:
Steering swivel and the pontic of the steeraxle of a kind of transport bridge of the present invention are rotationally connected by surface bearing, and decrease resistance when steeraxle turns to, resistance only has 1/10th of original resistance.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of the steeraxle of a kind of transport trolley of the present invention;
Fig. 2 is the structural representation of the first steering swivel.
Accompanying drawing indicates: 1, pontic, the 2, first hydraulic actuating cylinder, the 3, second hydraulic actuating cylinder, the 4, first steering swivel, the 5, second steering swivel, the 6, first surface bearing, the 7, second surface bearing, and 401, front spindle nose, 402, track arm, the 403, first through hole.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
With reference to Fig. 1, a kind of steeraxle of transport trolley, comprises pontic 1, first hydraulic actuating cylinder 2 and the second hydraulic actuating cylinder 3.The two ends, left and right of pontic 1 are separately installed with the first steering swivel 4 and the second steering swivel 5.First steering swivel 4 is rotationally connected with the left end of pontic 1 by the first surface bearing 6, and the second steering swivel 5 is rotationally connected with the right-hand member of pontic 1 by the second surface bearing 7.Be provided with the first lining in first steering swivel 4, the first lining is enclosed within above the first surface bearing 6, and lining can add surface bearing wear resisting property; Be provided with the second lining in second steering swivel 4, the second lining is enclosed within above the second surface bearing 7, and lining can add surface bearing wear resisting property.First hydraulic actuating cylinder 2 and the second hydraulic actuating cylinder 3 are symmetricly set on above pontic 1, first hydraulic actuating cylinder 2 one end is flexibly connected with pontic 1, its other end is flexibly connected with the first steering swivel 4, and second hydraulic actuating cylinder 3 one end is flexibly connected with pontic 1, and its other end is flexibly connected with the second steering swivel 5.
With reference to Fig. 2, the first steering swivel 4 is identical with the structure of the second steering swivel 5.First steering swivel 4 comprises track arm 402 and front spindle nose 401, and track arm 402 one end is welded with front spindle nose 401 one end, and front spindle nose 401 is provided with the first through hole 403, first through hole 403 near weld and installs for the first surface bearing 6.Track arm 402 is curved, and track arm 402 and front spindle nose 401 are obtuse angle away from the angle of weld one end.Steering swivel is by the cambered design of track arm 402, be obtuse angle with front spindle nose 401 away from the angle of described weld one end, and the triangle balanced design of track arm 402, hydraulic actuating cylinder and pontic 1, greatly impart alerting ability and safety that bridge transport vehicle turns to.
