Abstract
The utility model relates to transportation equipment, in particular to an entire frame structure of a transportation vehicle used under a coal well, which solves the problems of unreasonable structure and poor damping effect of the existing frame. The structure can improve the traction performance of coal vehicles, reduces tyre abrasion, and makes the stress of a frame reasonable. The entire frame is composed of a suspension frame, oil gas springs, a swing frame and a frame, wherein the swing frame is arranged at one end of the frame; the other end of the frame and the other end of the swing frame are respectively connected with one end of the suspension frame; the front part and the rear part of the entire transportation vehicle are respectively provided with an oil gas spring suspension structure; and the front oil gas spring and the rear oil gas spring are respectively arranged on the frame and the swing frame. The frame structure of the entire transportation vehicle is suitable for various roads, mines and underwell transportation vehicles, guarantees that all wheels have no suspension phenomenon in the process of traveling, always realizes that all the wheels are landed, and guarantees the power performance and the traction capability of vehicles. The oil gas springs are suspended, are stable to operate, and have high comfort.
Description
Technical field
The utility model relates to transportation device, is specially a kind of transport vehicle unitized frame structure that is used under the coal mine.
Background technology
The equipment of down-hole and mine transport vehicle unitized frame version all can't solve the unsettled phenomenon of individual wheel when using the hydro-pneumatic spring suspension type, its project organization major defect is:
1, the suspension damping effect is poor;
2, can't guarantee that individual wheel is unsettled;
3, version complexity, structure is not compact.
The utility model content
The purpose of this utility model is to provide a kind of transport vehicle unitized frame structure, solves problems such as existing body frame structure for automotive is unreasonable, damping effect difference, can improve the mine vehicle tractive property, reduces wear on tyres, makes vehicle frame stressed rationally.
The technical solution of the utility model is:
A kind of transport vehicle unitized frame structure, this structure are the unit frame of suspension, hydro-pneumatic spring, rocker, vehicle frame formation, and an end of vehicle frame is installed rocker, and each links to each other the other end of vehicle frame and the other end of rocker with an end of suspension; Respectively establish a hydro-pneumatic spring suspended structure before and after this unit frame, two hydro-pneumatic springs in front and back are installed in respectively on vehicle frame and the rocker.
Described transport vehicle unitized frame structure, the hydro-pneumatic spring suspended structure is that an end of two hydro-pneumatic springs in front and back is installed in respectively on vehicle frame and the rocker, each links to each other the other end of two hydro-pneumatic springs with the other end of suspension, and hydro-pneumatic spring on the rocker and rocker constitute suspended structure separately.
Described transport vehicle unitized frame structure, hydro-pneumatic spring is in tilted layout.
Described transport vehicle unitized frame structure adopts the girder of channel-section steel structure as vehicle frame, and girder one end is connected with rocker.
Described transport vehicle unitized frame structure, vehicle frame links to each other by bearing pin with rocker.
Described transport vehicle unitized frame structure, suspension links to each other by bearing pin with hydro-pneumatic spring.
The beneficial effects of the utility model are:
1, the utility model is a down-hole integral type transport vehicle body frame structure for automotive, transport vehicle hopper back door self-opening mechanism, base model is that vehicle frame, rocker, suspension and hydro-pneumatic spring are formed, vehicle frame has rocker, uses the hydro-pneumatic spring that is in tilted layout to hang, and two hydro-pneumatic springs in front and back are arranged on vehicle frame and the rocker, hydro-pneumatic spring on the rocker and rocker constitute suspended structure separately, rocker can realize that vehicle remains all wheels and lands when operation, guarantees tractive force, prevents that wheel is unsettled.
2, mode of motion of the present utility model is for when the touchdown point of front and back wheel during not on same plane, and vehicle frame and rocker relatively rotate by bearing pin, with landing all the time of assurance wheel.
3, the utility model is in the vehicle driving process, and during road bump, suspension is connected with rocker or vehicle frame by bearing pin, as oppositely supporting, realizes vibration damping by the bevelled hydro-pneumatic spring by stretching.
4, the utility model apparatus structure is reasonable, and working service is convenient, can under all kinds of harsies environment, use, and working stability.
Description of drawings
Fig. 1-Fig. 2 is the utility model structural representation; Wherein, Fig. 1 is a front view; Fig. 2 is the lateral plan of Fig. 1.
Fig. 3-Fig. 4 is the utility model motion scheme drawing.
Among the figure, 1 suspension; 2 hydro-pneumatic springs; 3 rockers; 4 vehicle frames; 5 wheels; 6 bearing pins; 7 bearing pins.
The specific embodiment
As Fig. 1-shown in Figure 2, the utility model transport vehicle unitized frame structure mainly comprises: the unit frame that suspension 1, hydro-pneumatic spring 2, rocker 3, vehicle frame 4 etc. constitute, one end of vehicle frame 4 is installed rocker 3, and each links to each other the other end of the other end of vehicle frame 4 and rocker 3 with an end of suspension 1; Respectively establish a hydro-pneumatic spring suspended structure before and after this unit frame, two hydro-pneumatic springs 2 in front and back are installed in respectively on vehicle frame 4 and the rocker 3.
In the present embodiment, the hydro-pneumatic spring suspended structure is that an end of two hydro-pneumatic springs 2 in front and back is installed in respectively on vehicle frame 4 and the rocker 3, each links to each other the other end of two hydro-pneumatic springs 2 with the other end of suspension 1, and the hydro-pneumatic spring 2 on the rocker 3 constitutes suspended structure separately with rocker 3.
In the present embodiment, adopt the girder of channel-section steel structure as vehicle frame 4, girder one end is connected with rocker 3.
In the present embodiment, vehicle frame 4 links to each other by bearing pin 6 with rocker 3, and can make rocker 3 serves as that revolution swings with bearing pin 6, guarantees that all wheels all land during with the realization Uneven road.
In the present embodiment, suspension 1 links to each other by bearing pin 7 with hydro-pneumatic spring 2, adopts the hydro-pneumatic spring form, good damping effect.Hydro-pneumatic spring is in tilted layout, and does not take space outerpace, arranges compact.
As Fig. 1-shown in Figure 2, in the vehicle driving process, when Uneven road, when pitching, at first the impulsive force up and down that bears of front and back wheel 5 can affact on the drive axle of wheel, and drive axle can be delivered to power on the suspension 1; At this moment, suspension 1 can be around bearing pin 7 left-hand revolutions; Simultaneously, hydro-pneumatic spring 2 will be given 1 one counteractions of suspension by bearing pin 7, to realize equilibrium of forces; Because hydro-pneumatic spring 2 has shock-absorbing function, so the vibrations that produce of jolting can tend to balance gradually.Secondly, as Fig. 3-shown in Figure 4, when Uneven road, the touchdown point at grade time that causes front and back wheel 5, rocker 3 begins to work, rocker 3 relatively rotates by bearing pin 6 and vehicle frame 4, adapts to wheel face in real time, and the realization vehicle guarantees that in driving process all wheels do not have unsettled phenomenon and take place, all the time realize that all wheels land, guarantee the tractive performance and the towability of vehicle; Hydro-pneumatic spring hangs, and is stable, the traveling comfort height.
