Description
Technical field
The invention belongs to the spacing steering hardware of a kind of artic traction seat, specifically a kind of traction seat synchronous turning device being made as one with traction seat.
Background technology
Along with the fast development of road transport, the high-mechanic that superimposed trailer has, economical, the features such as efficiency, receive the concern of industry, gradually become the main vehicle of long-distance logistics.But semi-trailer train is due to himself structure, in traveling (particularly running at high speed) and braking procedure, its stability decreases compared with bicycle, and produces the phenomenons such as some are distinctive as folding, whipping.The generation of these phenomenons adds the possibility that semi-trailer train has an accident, and is semi-trailer train considerable hurdle under steam.
Summary of the invention
The object of the invention is to solve existing artic in the middle of driving, because of traction seat and superimposed trailer corner out of control and cause the problem occurring accident, and a kind of traction seat synchronous turning device provided.
The present invention takes following technical scheme: a kind of traction seat synchronous turning device, comprise traction seat seat board, positioning plate, Unidirectional solenoid valve, maneuvering valve, counter steering bar assembly and hydraulic push rod, traction seat seat board front end is provided with the positioning plate be articulated and connected with it, hydraulic push rod is connected with bottom positioning plate, fix bottom the hydraulic push rod other end and traction seat seat board, hydraulic push rod is provided with pull back spring, the oil cylinder of hydraulic push rod is provided with the Unidirectional solenoid valve and maneuvering valve that control its switch, Unidirectional solenoid valve is by speed of a motor vehicle switch and brake switch parallel control, one end of maneuvering valve and counter steering bar assembly is articulated and connected, the other end of counter steering bar assembly is connected with the steering hardware of tractor truck by traction seat transmission component.
Described counter steering bar assembly comprises the pipe link I and pipe link II that are hingedly connected together, pipe link I one end is articulated and connected by bearing pin and maneuvering valve, hinged fixing with the piston rod of hydraulic push rod in the middle part of pipe link II, the pipe link II other end is connected with tractor truck steering hardware by traction seat transmission component.
Described positioning plate is cylindrical structure, and the bilateral symmetry of cylinder is provided with two curve slopes.
Described positioning plate is cylindrical structure, and the bilateral symmetry of cylinder is provided with two curve slopes, and curve slope is provided with step-like tooth, and the facade of profile of tooth is inclined-plane.
Described positioning plate is spherical structure, and the bilateral symmetry of sphere is provided with two curve slopes.
Described positioning plate is spherical structure, and the bilateral symmetry of sphere is provided with two curve slopes.Curve slope is provided with step-like tooth, and the facade of profile of tooth is inclined-plane.
When the speed of a motor vehicle is greater than setting value or brake switch pressure is greater than setting value, Unidirectional solenoid valve starts to be energized the oil duct one direction shut-off made between hydraulic push rod oil cylinder and petrol storage tank, and hydraulic push rod can not be compressed.When semi-trailer direction changing, there is folding distortion in the counter steering bar assembly be connected with steering hardware, thus pull maneuvering valve, make it open, another oil duct between the hydraulic push rod oil cylinder made and petrol storage tank is opened, thus the resistance making trailer crossbeam act on positioning plate curve slope reduces, and makes positioning plate move down.Reduce the distance that counter steering bar assembly pulls open because of folded deformation and hydraulic push rod simultaneously.When superimposed trailer wheel axis corresponding to pan position under positioning plate and the drive wheel of tractor truck and the axis of wheel flutter are handed over as time a bit, positioning plate moves down the distance that the distance that hydraulic push rod compress equals the shortening of counter steering bar folded deformation, and maneuvering valve cuts out.Thus the continuation limiting positioning plate is passive moves down, also limit the folding angles of superimposed trailer and tractor truck simultaneously.When turning to samsara timing, the pressure that semitrailer crossbeam acts on positioning plate arcwall face reduces, and makes hydraulic push rod under the effect of return spring, overcome check valve resistance in Unidirectional solenoid valve, makes positioning plate retracts position.
Compared with prior art, the present invention is by installing trailer crossbeam corner locating plate additional in traction seat seat board front end, make its corner by the constraint of tractor truck bearing circle, thus solve artic in the middle of driving, the corner because of traction seat and superimposed trailer is out of control and the accident that causes.Thus avoid the generation of the accidents such as appearance is folding, whipping.
