Background technology
bogie is owing to the restriction of its function, and volume is all comparatively huge, and its steering swivel system is weighed an important indicator of its performance especially.
It is no rotation direction sensor and little electric controller that the multi-axle steering system that
existing bogie adopts is set to all need steering trapezium structure, its shortcoming before and after the simple machinery, turns to precision low, is difficult for controlling; And strict to the locus of vehicle own, vehicle body is big, is difficult for using in the space-constrained place.
Summary of the invention
The purpose of
the utility model is to provide a kind of and can turns at narrow space, the multiaxis load-carrying vehicle disperse power steering swivel system that turns to flexibly easy to operate.
For achieving the above object, the technical scheme that the utility model adopts is:
A kind of multiaxis load-carrying vehicle disperse power steering swivel system, this steering swivel system comprises steering hardware and actuating unit,
Described steering hardware comprises that being installed in bottom of frame arranges steering wheel shafts, is connected first spindle arm on the described steering wheel shaft along left and right two of straight line setting, and adjacent two first spindle arms are connected through steering track rod;
Wherein: there are at least two described steering wheel shafts to be connected with respectively in the described steering wheel shaft of left and right two rows and turn to oil cylinder through second spindle arm,
Symmetrically arranged at least two described oil cylinder, at least two described steering wheel shafts of described steering track rod institute's bonded assembly of turning to are formed a steering unit among
left and right two rows.
preferably; Through the described action that turns to oil cylinder of solenoid-operated proportional multiway valve control whether little electric controller that described actuating unit comprises rotation direction sensor, be connected through signal with described rotation direction sensor and be the described Hydraulic Pump that turns to oil cylinder that hydraulic oil source is provided, described little electric controller.
further preferably, described rotation direction sensor is arranged on the center of any described steering wheel shaft.
preferably, described steering unit is provided with two or more sets.
Because the technique scheme utilization, the utility model compared with prior art has advantage and effect:
1, have the multi-steering axle set, can the steering effort left-right symmetric be distributed, arrange many group hydraulic rams simultaneously, disperse power reduces the car body maximum stress;
2, adopt many groups to turn to oil cylinder to use in pairs, turned to the oil cylinder series connection, coordinate to arrange, turned to the application force of oil cylinder output more reasonable; Vehicle width and dead weight of vehicle have been reduced; Improve the load-carrying capacity of vehicle, reduced vehicle and use the place, be specially adapted to the space-constrained place;
3, adopt many group steering track rods to connect each spindle arm successively, make vehicle when turning driving, tire can turn in synchronous interaction, reduces the deviation and the wearing and tearing of tire, improves tire service life, saves cost;
4, employing rotation direction sensor detect steering angle, and little electric controller control solenoid-operated proportional multiway valve, have improved the manoevreability that turns to of vehicle, accuracy.
