Background technology
Rail-road car is called combined car again, and perhaps public iron car is the corollary equipment of track traffic, is used for vehicle tractor-trailer train in orbit, and accurately contraposition in orbit.Combined car also interior other of the section of can be used for is shunt and the contraposition operation.It is power supply that combined car generally adopts storage battery, but both on the various tracks of traveling gauge 1435mm in car depot, also can travel in the smooth-riding surface.Combined car possesses pilot steering, two kinds of modes of wireless remote control.Combined car is equipped with the fixed type automatic car coupler, has the function with train automatic car coupler hook such as subway, and the train driving platform possesses automatic uncoupling function simultaneously.
The automobile-used draw gear of public iron is company's extension and the traction that realizes between road and rail double duty tractor and the rail vehicle, is applicable to car depot, the tasks such as rescue on locomotive depot and the railway.
Current, it is unreasonable that the automobile-used draw gear of public iron arranges length, and the departure angle of vehicle on highway is less, the road running safety is not high, and is when public iron car railway travels, minimum bigger by radius of curve, public iron car lacks alerting ability at work, derails in distraction procedure easily.
Summary of the invention
The purpose of this invention is to provide a kind of combined automobile-used draw gear, to solve the problems referred to above that prior art exists.
In order to finish the object of the invention, the invention provides a kind of combined automobile-used draw gear, comprise that hitch, coupler seat, described hitch captive joint with coupler seat, also comprise by metal sheet be welded draw bar, traction seat, one end of described draw bar is captiveed joint with described coupler seat, described draw bar is provided with pin-and-hole, and draw bar is connected with described traction seat by the bearing pin that passes described pin-and-hole.
Wherein, described coupler seat is provided with the bolt hole of four oval hole shapes, and described hitch is connected by four bolts with described coupler seat.
Wherein, the described draw bar left and right sides is provided with centralizing spring, and an end of described centralizing spring is connected with described draw bar, and the other end is connected with described traction seat.
Wherein, also comprise recoil spring, described hitch comprises gib head and coupler body, and an end of described recoil spring is connected with described gib head, and the other end is connected with described coupler body.
The present invention mainly can pack up the hitch swing by draw bar being set and increasing the pin-and-hole design at draw bar, has reduced the length of car load, improves the alerting ability that moves on highway and the railway; Secondly, by the design of slotted hole, can realize the adjustment of hitch on short transverse; Again, the both sides of draw bar are provided with centralizing spring, have guaranteed that the pendulum angle of hitch when towage is less, improve the safety of towage.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail.
Shown in accompanying drawing 1, accompanying drawing 2, accompanying drawing 3, accompanying drawing 4, accompanying drawing 5,
The invention provides a kind of combined automobile-used draw gear, comprise that hitch, coupler seat, described hitch captive joint with coupler seat, also comprise by metal sheet be welded draw bar, traction seat, one end of described draw bar is captiveed joint with described coupler seat, described draw bar is provided with pin-and-hole, and draw bar is connected with described traction seat by the bearing pin that passes described pin-and-hole.。
The draw bar design has pin-and-hole, can swing around traction seat, and after towage finished, it was parallel hitch can be swung to the rear end, compartment, hitch is packed up and fixed, and reduces the vibration of vehicle in operational process, makes tractor truck more steady in operational process.Draw bar is according to the design of work operating mode, and draw bar is welded by low alloy steel plate.
Wherein, described coupler seat is provided with the bolt hole of four oval hole shapes, and described hitch is connected by four bolts with described coupler seat.Hitch is connected with four bolts with coupler seat, and what bolt hole adopted is slotted hole, can realize the adjustment of hitch on short transverse, can eliminate manufacturing errors during assembling, improves the assembly precision of hitch.
Wherein, the described draw bar left and right sides is provided with centralizing spring, and an end of described centralizing spring is connected with described draw bar, and the other end is connected with described traction seat.When centralizing spring can prevent the vehicle light locomotive running, the gib head pendulum angle was excessive and cause potential safety hazard.
Wherein, hitch can adopt KD-5 type hitch, also comprises recoil spring, and described hitch comprises gib head and coupler body, and an end of described recoil spring is connected with described gib head, and the other end is connected with described coupler body.Recoil spring be used for relaxing train be in operation owing to the variation of tractive force or when starting, braking and the shunting service vehicle collide longitudinal impact and the vibration that causes mutually, thereby alleviate the destructive effect to body construction and lade.
Hitch is mainly realized the company's extension between the two cars.Hitch up and down apart from can arbitrarily adjusting in the scope of design, brings great convenience for the assembling of hitch when assembling.
The hook shadoof can realize the hitch locking, unblank and three state positions of standard-sized sheet, the hitch of combined tractor truck and train connected hang or decoupling device.
Draw bar is welded by low alloy steel plate, guarantees the strength and stiffness of draw bar when towage, guarantees safety.
Fixed latches is to swing to when packing up with the rear end, compartment is parallel at hitch hitch is fixed, and guarantees that tractor truck big shock and vibration can not take place when high-speed cruising, reduces the curve negotiating radius at railway.
Traction seat mainly is made up of two block plates up and down, and being connected of realization and draw bar is for the swing of hitch provides enough spaces.
Fixed latches is used for fixedly hitch, prevents combined tractor truck when highway or railway operation (light locomotive running), hitch whipping and cause safety misadventure; During again as the rail traction operation, the traction bearing pin.
The combined automobile-used draw gear of the present invention, design by slotted hole, can realize the adjustment of hitch on short transverse, the hitch swing can be packed up by draw bar being set and increasing the pin-and-hole design at draw bar, reduced the length of car load, improved the alerting ability that moves on highway and the railway, the both sides design of draw bar has centralizing spring, guaranteed that the pendulum angle of hitch when towage is less, improved the safety of towage.
Those of ordinary skill under the prerequisite that does not break away from the principle of the invention, can also be made some improvements and modifications, and these improvements and modifications also should be considered as protection scope of the present invention.
