Abstract
The utility model discloses an aircraft tractor straight line walking controller which comprises a vehicle body controller, an angular transducer and a hydraulic steering gear. The hydraulic steering gear comprises an electromagnetic servo hydraulic valve, a hydraulic pump and a hydraulic oil cylinder. The vehicle body controller is respectively and electrically connected with the angular transducer and the hydraulic steering gear. The angular transducer is respectively arranged on a front axle and a rear axle of a tractor. According to the aircraft tractor straight line walking controller, a deflection angle of a vehicle axle is collected through the angular transducer and is sent to the vehicle body controller. Angular difference can be compared by the vehicle body controller through calculation of the angle. Front vehicle wheels can be controlled through the hydraulic steering gear so that the problem that an aircraft tractor can not be controlled easily to travel in a straight line due to four-wheel steering design is solved.
Description
Technical field
The utility model relates to the vehicle to run control setup, particularly a kind of aircraft towing straight line moving controller.
Background technology
Existing aircraft towing, because of its four-wheel steering design, vehicle easily departs from original travel direction under the impact of road conditions, when manually controlling, the staff is difficult to real straight line moving, thereby the phenomenon that automatic turning occurs, these phenomenons do not allow to occur when towing aircraft carries out straight line moving.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides a kind of aircraft towing straight line moving controller.
The technical scheme that solves the problems of the technologies described above is: aircraft towing straight line moving controller, comprise car body controller, angular transducer and hydraulic steering gear, and hydraulic steering gear comprises electromagnetic servo hydraulic valve, Hydraulic Pump and hydraulic reservoir; Described car body controller is electrically connected to described angular transducer and described hydraulic steering gear respectively; Described angular transducer is arranged at respectively on the front-rear axle of tractor truck; Described hydraulic steering gear comprises electromagnetic servo hydraulic valve, Hydraulic Pump and hydraulic reservoir; Described electromagnetic servo hydraulic valve is connected with described Hydraulic Pump and hydraulic reservoir respectively.
The beneficial effects of the utility model are: the deflection angle of collecting vehicle bridge by angular transducer is passed to car body controller, car body controller is through calculating relatively differential seat angle of angle, control front vehicle wheel by hydraulic steering gear, thereby solved aircraft towing because the four-wheel steering design causes straight line moving heavy handled problem.
Description of drawings
Fig. 1 is the structural representation of aircraft towing straight line moving controller.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further elaborated.
As shown in Figure 1, aircraft towing straight line moving controller comprises car body controller 1, angular transducer 2 and hydraulic steering gear, and hydraulic steering gear comprises electromagnetic servo hydraulic valve 3, Hydraulic Pump 4 and hydraulic reservoir 5; Described car body controller 1 is electrically connected to described angular transducer 2 and described hydraulic steering gear respectively; Described angular transducer 2 is arranged at respectively on the front-rear axle of tractor truck;
The principle of work of above-mentioned aircraft towing straight line moving controller is: load onto respectively angular transducer 2 on the front-rear axle of car, angular transducer 2 with the deflection angle of vehicle bridge real-time send car body controller 1 to; Car body controller 1 calculates and relatively deflection angle is poor, feeds back to carry out electromagnetic servo hydraulic valve 3, and Hydraulic Pump 4 controlled by electromagnetic servo hydraulic valve 3 and hydraulic reservoir 5 carries out work, controls front vehicle wheel by hydraulic steering gear, realizes turning to of two wheels; As long as the assurance front and rear angles unanimously can be realized the rectilinearity of walking and control, thereby the straight line moving of real tractor truck is controlled.
