Abstract
The utility model discloses a steering traction mechanism for a flat car. The steering traction mechanism comprises more than two steering wheel sets (7) fixed on a car frame, wherein rotating arms (5) are arranged on the steering wheel sets (7), the rotating arms (5) are hinged with a connecting rod (6), the connecting rod (6) is hinged with a drawbar (3), and one end of the drawbar (3) is hinged with a towing hinge support (8) mounted on the car frame. The connecting rod is connected with the rotating arms and the drawbar to form a rhomboid swing bar linkage mechanism; the direction of the drawbar can be in accordance with the running directions of wheels, the wheels of the flat car can be guaranteed to be in stable uniform-distribution state in the range of a carriage and under any states, and the stability is good; and the turning radius is small during running, and the use is flexible. As a pull rod is hinged with the drawbar, the steering traction mechanism can adapt to differential height changes of an interface of a power traction device. When the flat car is parked, the pull rod can be turned over, so that smaller parking space is occupied.
Description
Technical field
The utility model relates to a kind of trailer coupling, particularly relates to the trailer coupling that turns to that a kind of flat truck uses, and belongs to equipment technology field of transport.
Background technology
In traditional trailer platform mechanism, what generally adopt is the mechanism that pulls round of central rotating shaft structure, is used for the tractor truck of mailbag, luggage transportation as Railway station, adrm etc.The central rotating shaft structure of this car pull round mechanism must be wheel apical margin must and vehicle frame between keep movement clearance, increase along with load like this, wheel diameter also increases, the height of vehicle frame will increase thereupon, but cause operative weldability to descend; The front-wheel supporting system is along with angle of turn increases this steering hardware in steering procedure, and its supporting stability will reduce, so this traditional tractor truck can only be used for little tonnage (load), load more uniform occasion in car.
Summary of the invention
The purpose of this utility model is, the trailer coupling that turns to that a kind of flat truck uses is provided.Be applicable to various flat trucks, particularly be applicable to the flat truck of big load, good stability.
The technical solution of the utility model: a kind of flat truck is used turns to trailer coupling, comprise the wheels that turn to that are fixed on more than two on the vehicle frame, turn to wheels to be provided with pivoted arm, pivoted arm and rod hinge connection, connecting rod and draw bar are hinged, and an end of draw bar is hinged with the traction free bearing that is installed on the vehicle frame.
What aforementioned flat truck was used turns in the trailer coupling, and described draw bar is hinged through hinge and pull bar.
What aforementioned flat truck was used turns in the trailer coupling, and described pivoted arm is through hinge pin and rod hinge connection.
Compared with prior art, connecting rod of the present utility model is connected with draw bar with pivoted arm respectively, constitutes parallelogram fork link gear; The direction that can obtain draw bar is consistent with the wheel direction of travel, can guarantee that the wheel of flat truck is uniform stabilized conditions, good stability in the compartment scope under any state; Turn radius in service is little, uses flexibly.Hinged by pull bar and draw bar, the interface discrepancy in elevation that can adapt to dynamic traction device changes.When parking, pull bar can be dug, can obtain less parking space.The utility model is particularly suitable for big load flat truck.The utility model can not change the supporting stability of front-wheel in steering procedure; Wheel only needs less space in turning to, therefore can be embedded within the vehicle frame excess room, the height of vehicle frame is reduced, but keep operative weldability preferably; The utility model steering hardware can be realized many groups (even number) configuration, thereby obtains the technological effect of the little wheel load of big load.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Being labeled as in the accompanying drawing: the 1-pull bar, the 2-hinge, the 3-draw bar, the 4-hinge pin, the 5-pivoted arm, the 6-connecting rod, 7-turns to wheels, and 8-draws free bearing.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples, but not as to any restriction of the present utility model.
Embodiment.
The utility model as shown in Figure 1.A kind of flat truck is used turns to trailer coupling, comprise being fixed on more than two turning to wheels 7 on the vehicle frame that turn to wheels 7 to be provided with pivoted arm 5, pivoted arm 5 is hinged with connecting rod 6, connecting rod 6 is hinged with draw bar 3, and an end of draw bar 3 is hinged with the traction free bearing 8 that is installed on the vehicle frame.Described draw bar 3 is hinged through hinge 2 and pull bar 1.Described pivoted arm 5 is hinged through hinge pin 4 and connecting rod 6.
Principle of work of the present utility model
But wheels 7 coaxial lines that turn to of the present utility model dispose more than 2 (even number); Traction free bearing 8 is configured in the centre that turns to the wheels axis; Fastening between pivoted arm 5 and the axle sleeve that turns to wheels by being threaded; Connecting rod 6 is connected with draw bar 3 with pivoted arm 5 respectively by hinge pin 4; Described connecting rod 6, pivoted arm 5 and draw bar 3 connect into parallelogram fork link gear; The direction that can obtain draw bar 3 is consistent with the wheel direction of travel; Pull bar 1 is hinged by hinge 2 with draw bar 3, and the interface discrepancy in elevation that can adapt to dynamic traction device changes.When parking, pull bar 1 can be dug, can obtain less parking space.Tractive force acts on the traction free bearing 8.
Claims (3)
1. a flat truck is used turns to trailer coupling, it is characterized in that: comprise being fixed on more than two turning to wheels (7) on the vehicle frame, turn to wheels (7) to be provided with pivoted arm (5), pivoted arm (5) is hinged with connecting rod (6), connecting rod (6) is hinged with draw bar (3), and an end of draw bar (3) is hinged with the traction free bearing (8) that is installed on the vehicle frame.
