Abstract
The utility model provides a steering device of a heavy-duty flatcar. The steering device comprises a hydraulic cylinder, a piston rod, a guiding wheel set, a gear and a swinging piece. At least one end of the piston rod is connected with the hydraulic cylinder, a rack is arranged on the surface of the piston rod, and the guiding wheel set is connected with the bottom of the piston rod. The rack is meshed with the gear, the gear and the swinging piece are fixedly connected through a bolt, the swinging piece is connected with a flatcar body through a mandrel, and the swinging piece rotates with the mandrel as the center. The swinging assembly of the steering device adopts a gear rack transmission mode, linear motion of the hydraulic cylinder is transferred to the rotation gear through the rack on the piston rod, and an effect of rotating the wheel set is achieved. A transmission mode between the gear and the rack is that a protrusion which is several centimeters high is meshed with a recess, the structure is compact, working performance of the swinging assembly is improved, and installing space is greatly reduced.
Description
Technical field
The utility model relates to the steering hardware technical field of mobile flatcar, especially, relates to a kind of steering hardware of load-carrying flatcar.
Background technology
The load-carrying flatcar of various movements is used to transport travel engineering equipment or material, such as the trackless traverse table that uses in subway, locomotive manufacturing or transhipment, the beam transportation vehicle that bridge construction is used etc.This heavy duty flatcar need to be realized traction and turning function mostly, and the realization of turning function is mainly swinging gear ground-engaging wheel group at present, its angle that swings to needs is completed turned to.Existing wobble component mostly is swing-bar mechanism, adopts the Driven by Hydraulic Cylinder fork more, thereby drives the wheels rotation, and this mechanism needs larger revolution space, and is easily not steady while being not easy layout and rotation.
The utility model content
The utility model purpose is to provide a kind of steering hardware of load-carrying flatcar, with solution, takes up room greatly, rotates jiggly technical matters.
For achieving the above object, the utility model provides a kind of steering hardware of load-carrying flatcar, comprises hydraulic actuating cylinder, piston rod, guiding wheels, gear and swing component,
At least one end of described piston rod is connected with described hydraulic actuating cylinder, and described piston rod surface is provided with tooth bar, and described piston rod bottom is connected with the guiding wheels;
Described tooth bar and described gear are intermeshing, and described gear and described swing component are bolted to connection, and described swing component is connected to flat car car body by mandrel, and described swing component rotates centered by described mandrel.
Preferably, the relative both sides of described gear are provided with described piston rod, and the tooth bar of described piston rod surface and described gear are intermeshing.
Preferably, described mandrel is fixed central spindle, and described swing component is connected to fixed central spindle by bearing.
Preferably, described fixed central spindle is welded to connect by fixed operating sleeve and flat car car body.
Preferably, be connected for key between described fixed central spindle and described fixed operating sleeve.
Preferably, the anglec of rotation of described swing component is 0 °-180 °.
The utlity model has following beneficial effect:
1, compact conformation: the wobble component of the utility model steering hardware has adopted the type of belt drive of rack-and-gear, and the straight-line motion of hydraulic actuating cylinder is passed to swing pinion by the tooth bar on piston rod, thereby plays the effect of rotation wheels; Type of belt drive between gear and tooth bar is intermeshing by projection and the depression of several centimetres high, compact conformation, and installing space can greatly compress;
2, transmission accuracy is high: move in turn successively between gear and tooth bar, and drive simultaneously swing component and rotate centered by mandrel, then the road wheel that drives under flat firmly body rotates, realize pure mechanical drive, precision is high and stationarity good.
Except purpose described above, feature and advantage, the utility model also has other purpose, feature and advantage.Below with reference to figure, the utility model is described in further detail.
