Description
Technical field
The present invention relates to a kind of vehicle steering device, more particularly to one kind is for tracked ATV articulation steering dress
Put.
Background technology
China region is broad, and landform is more complicated, and lake, river, marsh are numerous, and flood, landslide, forest are big
The frequent natural calamities such as fire.It is difficult to reach the site of an accident in time by traditional vehicle, often misses optimal rescue opportunity,
Serious loss is caused to the country and people.
Tracked ATV essentially consists in personnel's Material Transportation, the rescue under various complicated severe road conditions, so that
Determine that it must have stronger cross-country power and excellent maneuverability.Steering behaviour is to evaluate tracked ATV
One of leading indicator of energy, therefore articulated mounting of the research with good steering behaviour is for improving vehicle overall performance with heavy
Want meaning.
Conventional track Vehicular turn mode mainly has glide steering mode, bend steering mode and electric hydraulic steering system.
Glide steering reduces the thrust of inner track by increasing the thrust of outer track so that vehicle obtains one and turns
To torque, steering resisting moment is than larger during due to turning to, therefore endless-track vehicle needs the power of consumption very big in steering procedure.
In addition under the conditions of complicated severe road conditions, using glide steering, it is excessive that endless-track vehicle will face slip rate in the process of moving, car
Sideslip, turn to it is difficult, the problems such as stability difference.Due to being limited by crawler belt itself flexibility, steering procedure is needed bend steering mode
Radius of turn that will be very big, steering behaviour is poor.The current steering for comparing forward position has electric hydraulic steering system, but electro-hydraulic steering
There is many difficult points, the nonlinear characteristic of such as electrohydraulic system, with the dead band of load change, asymmetrical non linearity in the design of system
The characteristic such as gain and hysteresis delay, saturation.
The content of the invention
In view of the shortcomings of the prior art, the present invention is intended to provide a kind of hinge between tracked ATV Dual module
Transfer is connect, the device can provide multiple frees degree without elastic restraint, can significantly improve the cross-country energy of all-terrain vehicle
Power and mobility, and can ensure that the ride comfort under complex road condition.
To achieve the above object, technical solution of the invention is：A kind of tracked ATV articulated steering device,
The articulated steering device connects front module car body and rear module car body；The articulated steering device include front module bracket assembly,
Preceding hydraulic damper assembly, preceding steady pin, two hydraulic steering cylinders, clutch can fore-stocks, it is hinged rotational pin, clutch can, rear solid
Rationed marketing, clutch can after-poppet, rear hydraulic damper assembly, rear module bracket assembly are constituted；The front module bracket assembly 1 is connected
Front module car body, module car body after the rear connection of module bracket assembly 11, props up before the front module bracket assembly 1 and clutch can

It is connected with the steering pipeline of front module car body to the front end of hydraulic cylinder 4, the rear end of the hydraulic steering cylinder 4 passes through steady pin
It is hinged with the front end of clutch can 7, middle hydraulic cylinder and the clutch can fore-stock 5 of the hydraulic steering cylinder 4 are hinged, the preceding hydraulic pressure
Vibration damper assembly 2 is hinged on clutch can fore-stock 5, between the rear end of clutch can fore-stock 5 and clutch can 7 by be hinged turn
Dynamic pin 6 is connected, and is hinged by rear steady pin 8 between the clutch can after-poppet 9 and rear module bracket assembly, the clutch can 7
Can be rotated around clutch can after-poppet 9, the rear hydraulic damper assembly 10 is hinged on clutch can after-poppet 9.
Preferably, by being hinged rotation pin connection between the clutch can fore-stock rear end and clutch can.
Preferably, described front module bracket assembly one end is connected with front module car body, and the other end leads to clutch can fore-stock
Preceding steady pin is crossed to be hinged；Described rear module bracket assembly one end is connected with rear module car body, and the other end leads to clutch can after-poppet
Later steady pin is hinged；Clutch can be rotated around clutch can after-poppet.
Preferably, described two hydraulic steering cylinders are symmetricly set in the both sides of clutch can fore-stock；The hydraulic steering cylinder
One end be connected with the steering pipeline of front module car body, the other end of hydraulic steering cylinder is by steady pin and clutch can front end
It is hinged, middle hydraulic cylinder and the clutch can fore-stock of hydraulic steering cylinder are hinged.
Preferably, the preceding hydraulic damper assembly is hinged on clutch can fore-stock.
Preferably, the rear hydraulic damper assembly is hinged on clutch can after-poppet.
The beneficial effects of the invention are as follows：The articulated steering device turns to machine by special knuckle and hydraulic pressure Aided Machine
Structure connects front and rear module car body, and standard endless-track vehicle is different from during steering, but by controlling two hydraulic cylinders in left and right
Change the angular separation between forward and backward module, a module reaction force is tackled the energy loss of another module, drop significantly
Low steering force and energy loss, enhance the cornering ability of vehicle, and ensure that the same track turning operation of forward and backward module,
It is achieved in the radius of turn of the maximum 43 ° steering angle of vehicle and minimum 6.5m；
When vehicle runs into complex road condition, articulated mounting can also realize the luffing angle of 20 ° of maximum between car body, Yi Ji
The maximum 30% inclination gradient is capable of achieving on slope；
When vehicle runs into barrier or trench, under the driving of front module, vehicle can be made to pass through 500mm obstacles high
Thing；Simultaneously can also be by trench the largest of about 1m wide.
It is difficult that articulated steering device of the invention overcomes traditional binodal Vehicular turn, inconvenient operation, and can not be real
The limitation of existing pitching.By using the articulated mounting, the cross-country power of vehicle is significantly enhanced and by property, moreover,
Ride comfort and ride comfort when front and rear hydraulic damper also ensures that vehicle runs.
