Abstract
The utility model discloses a round concave axle applied to a trailer. The axle comprises an axle head, an axle shoulder, an axle body and a connecting plate, wherein the axle head is connected with the axle shoulder, the connecting plate is connected between the axle shoulder and the axle body, the central line of the axle body is lower than that of the axle head, and the axle shoulder and the axle body enable the axle to form a concave position through the connecting plate. According to the axle for the trailer, double requirements of loading capacity and convenient loading are satisfied simultaneously under the condition that the height of a cargo truck is limited, and the axle with a super-low sweeping board is provided for the trailer.
Description
Technical field
The utility model relates to automobile technical field, more particularly, relates to the recessed axle of a kind of circle.
Background technology
Along with transportation market further to external expansion, the technology of road transport vehicle has had significant progress, the range of use of common trailer is also more and more wider.Trailer car shaft is servo-actuated axletree, bearing vehicle weight and cargo load, and for the support tire rotation, it mainly comprises axis body, wheel hub, brake wheel, brake shoe assembly, reaches camshaft assembly, axis body is divided into the spindle nose two large divisions at central siphon and two ends, wheel hub, brake drum assembly are assemblied on the spindle nose at axis body two ends, be used for carrying out vehicle wheel rotation and braking, the brake shoe assembly is installed in the brake wheel, its brake facing is made by the asbestos less friction environment-friendly materials, interior outer bearing is installed between spindle nose and wheel hub, and installs fixing by the axis head nut assembly.
And at present common axletree is that spindle nose and central siphon are at the d-axis of same axial line, in some special purposes, such as carrier loader, the tank car of part special purpose, caravan, in order to reach more bearing capacities and to satisfy the requirement of discipline of road traffic, particularly for the semitrailer that uses the Double layer loading flatlike structure, they need a lower loading areal of support, and the one, in order to reduce the height of car load, the 2nd, in order to reduce the center of gravity of carrier, make driving safer.In order to reduce the height that loads areal of support, then need the axletree of suitable with it low-mounting height, and common d-axis can't address this problem at present, therefore, research and develop that a bearing capacity is good, the spill axletree of compact conformation and driving stability is best selection.
The utility model content
The deficiency that the utility model purpose exists in order to overcome above-mentioned prior art, a kind of circular recessed axle that the dull and stereotyped areal of support height of vehicle loading is decreased is provided, thereby chassis of trailer is reduced, improve vehicle delelivered payload capability, make things convenient for car loading operation, to be fit to the needs of the south east asia transportation markeies such as India.
Technical solutions of the utility model are as follows: the circular recessed axle of a kind of trailer, its axis body comprises spindle nose, the shaft shoulder, axle body, described spindle nose is connected with the shaft shoulder, be connected with connecting panel between the described shaft shoulder and axle body, the line of centers of described axle body is lower than the line of centers of spindle nose, and the described shaft shoulder and axle body make described axis body form recess by connecting panel.
Described axle body and spindle nose are hollow circular-tube.
Described spindle nose and the shaft shoulder are whole single type structures.
Described connecting panel is provided with two axis holes.
Connection mode by interference fit between the described shaft shoulder and the described connecting panel compresses rear welding.
Connection mode by interference fit between described axle body and the described connecting panel compresses rear welding.
The relative shaft shoulder of described axle body offsets downward the distance of 120-130mm.
The first-class height of described diaxon, the axis keeping parallelism of the axis of described two spindle noses and described axle body.
The utility model compared with prior art, its beneficial effect is:
The recessed axle of circle of the present utility model effectively reduces the height of the cargo bed of vehicle, thereby the vehicle frame that makes trailer can conveniently load the cart meeting the high-level while of limit, safer stable, the cargo capacity of vehicle driving is guaranteed greatly, for the southeast asian markets such as India provide a kind of axletree that more meets the ultralow freight of market demand.
Description of drawings
Fig. 1 is the structural representation of the circular recessed axle of the utility model trailer;
Fig. 2 is the axle tube structure schematic diagram of the circular recessed axle of trailer shown in Figure 1.
The specific embodiment
Below pass through the specific embodiment, and the utility model is described in further detail by reference to the accompanying drawings.
As shown in Figure 1 and Figure 2, the utility model discloses the circular recessed axle of a kind of trailer, it comprises spindle nose 11, the shaft shoulder 12, connecting panel 13 and axle body 1 four parts, wherein axle body is the hollow shaft tubular construction, connect the circular recessed axle two ends shaft shoulder, axle body is connected by connecting panel with the two ends shaft shoulder, and axle body 1 is ф 127x15 hollow circular-tube.Connecting panel is tabular, the centre has two circular holes, two circular hole distance of center circle are 120-130mm, the aperture is suitable with the shaft shoulder and axle body diameter respectively, the shaft shoulder and axle body insert in the connecting panel circular hole from both sides,, make the axle body height be lower than spindle nose and the shaft shoulder and form the spill axis body along the excircle configuration welding of the shaft shoulder and axle body in the connecting panel both sides, make wheel hub and axle body form eccentric structure, thereby the loading platform plate height of trailer is minimized.
Referring to Fig. 1, the recessed axle of circle of the present utility model is the servo-actuated axletree of trailer.Its spindle nose part mainly comprises brake wheel 2, wheel hub 3, wheel hub cover 4, outer bearing 5, neck bearing 6, oil sealing 7, cover of dust 8, brake wheel 2, wheel hub 3, be assemblied on the spindle nose 11, be used for carrying out vehicle wheel rotation and braking, 3 of spindle nose 11 and wheel hubs are equipped with hub oil seal 7, neck bearing 6, outer bearing 5, hub oil seal 7 is installed in the most inboard of wheel hub 3, the inner ring of neck bearing 6 is fixed on the step 21 of spindle nose 11, the outer ring of neck bearing 6 is resisted against first spacing 31 of wheel hub 3, the outer ring of outer bearing 5 is resisted against second spacing 32 of wheel hub 3
It is recessed that the circular recessed axle of the utility model changes to axle body by original d-axis, and spindle nose and axle body all by the hollow circular-tube of shaft shoulder welding, are compared with the square tube of equal external diameter, and the anti-bending strength of pipe is stronger.The axletree axle body is when sweep is combined, because there are the vertical shift distance of 120-130mm in axle body line of centers and spindle nose axis, sweep also must be with the vertical distance of the 120-130mm that descended, realized the ultralow flat board of trailer, the transport vehicle that has also solved certain areas should guarantee to transport the problem that cargo capacity conveniently loads the cart again in the limit for height situation.
