Description
Technical field
The utility model relates to a kind of Trailer car shaft more particularly to a kind of segmented Trailer car shafts.
Background technique
Automotive axle is connected by suspension with vehicle frame, and wheel is installed at both ends.The effect of vehicle bridge be subject to automobile load,
Abrupt deceleration vehicle maintains normally travel of the automobile on road.Trailer generally passes through the tractor driving in front, is located at trailer car body
Under vehicle bridge belong to bearing bridge, play the role of load-bearing, the main body of bearing bridge is axle, and bearing capacity depends on the property of axle
Energy.In the prior art, axle is usually monoblock type, and like a huge barbell, both ends pass through suspension system supports vehicle
Body, so the both ends of axle belong to weight bearing area.
In the prior art, the both ends of axle are small compared with middle part size, and the blank for processing axle is hollow seamless pipe, is needed
Both ends are reduced in size to specified size by hot extrusion, lead to the in uneven thickness of both ends, weight bearing area is easy to appear defect,
Axle is influenced using the safe and axle service life, so generally using thicker straight tube as blank, but axle overall weight increases
Add very much, not only cost improves, and also reduces the transport capacity of trailer, does not meet light-weighted requirement.
Summary of the invention
During Trailer car shaft R&D and production, it is found that the main body of Trailer car shaft primarily serves supporting role, Trailer car shaft
Principal length is maximum, and weight accounting is maximum, even if wall thickness reduces, is also able to satisfy requirement, moreover it is possible to save cost；And Trailer car shaft axis
Head primarily serves carrying effect, and weight accounting is small, and wall thickness determines the bearing capacity of Trailer car shaft, and the trailer vehicle of the prior art
Axis is due to being to be integrally formed, and the thickness of spindle nose is too many at the worst relative to axle body, and the wall thickness of spindle nose is also uneven, is easy
Existing defect, therefore in order to improve bearing capacity, it has to improve the wall thickness of axle entirety.So, if it is possible to reduce trailer vehicle
The wall thickness of shaft body, while increasing the wall thickness of Trailer car shaft spindle nose, the weight of Trailer car shaft entirety can not only be reduced, additionally it is possible to
Improve the bearing capacity of Trailer car shaft.
To solve the above-mentioned problems, the utility model provides a kind of segmented Trailer car shaft, and it is high, light to provide a kind of intensity
The segmented Trailer car shaft of quantization.To achieve the above object, a kind of technical solution that the utility model is taken are as follows: segmented trailer
Axle, including axle body and load receiving part, the axle body are set as hollow cylindrical tube or square tube construction, axle
The both ends of main body are provided with variable diameter auxiliary section, are provided with load receiving part on the outside of variable diameter auxiliary section, the load receiving part is in the axial direction
It is set as ladder shaft-like structure, load receiving part is internally provided with tubaeform inner hole, load-bearing is processed by way of forging or casting
Portion guarantees uniform thickness, improves bearing capacity, and load receiving part, which is fixed by way of friction welding with variable diameter auxiliary section, to be connected
It connects.
Further, the outer surface of the outer surface of load receiving part and variable diameter auxiliary section constitutes tendency axial line, predetermined angle
Angle, the angle is set as 0.6-1 °.
Compared with prior art, the utility model has the following beneficial effects: the structure using segmented designs, axle master
The thickness of body further decreases, and the thickness of load receiving part increases, and size is more uniform, and overall weight reduces, and cost decline is held simultaneously
Loading capability further increases, and practicability is very strong.
Detailed description of the invention
The utility model is described in further detail below in conjunction with attached drawing.
Attached drawing 1 is the structural schematic diagram of the utility model；
Attached drawing 2 is the partial enlargement diagram of weld A；
Attached drawing 3 is the structural schematic diagram of axle body；
Attached drawing 4 is the structural schematic diagram of load receiving part；
In attached drawing: 1, axle body, 2, load receiving part, 3, variable diameter auxiliary section.
Specific embodiment
In order to enable those skilled in the art to better understand the technical solutions of the present invention, 1, attached drawing with reference to the accompanying drawing
2, attached drawing 3, attached drawing 4 and specific example are described further the utility model.
As shown in attached drawing 1, attached drawing 3 and attached drawing 4, a kind of segmented Trailer car shaft, including axle body 1 and load receiving part 2, institute
The axle body 1 stated is set as hollow cylindrical tube or square tube construction, and the both ends of axle body 1 are provided with variable diameter auxiliary section
3, load receiving part 2 is provided on the outside of variable diameter auxiliary section 3, and the load receiving part 2 is set as ladder shaft-like structure, load-bearing in the axial direction
Portion 2 is internally provided with tubaeform inner hole, and load receiving part 2 is processed by way of casting or forging, and guarantees uniform thickness, improves
Bearing capacity, load receiving part 2 are fixedly connected by way of friction welding with variable diameter auxiliary section 3.
Further, as shown in Fig. 2, the outer surface of the outer surface of load receiving part 2 and variable diameter auxiliary section 3 constitutes tendency axle center
Line, predetermined angle angle, the angle are set as 0.6-1 °.
Further, the wall thickness of axle body 1 is set as 10mm, and the wall thickness of variable diameter auxiliary section 3 is set as 18mm.Axle master
Body 1 is not the main portions of load-bearing, and the original wall thickness of axle body 1 is set as 12mm, and thickness further decreases, and is not influencing to make
In the case where, the weight of axle body 1 is reduced, cost decline.
Further, the wall thickness at 2 stress of load receiving part is set as 26mm.Wall thickness at 2 stress of load receiving part is much larger than axle
The wall thickness of main body 1, bearing capacity is stronger, and casting or forging workpiece size are uniform, it is not easy to generate defect, also improve safety
Property.
The working principle and the course of work of the utility model are as follows: the axle of the prior art is integral type, the two of vehicle bridge
End rolls into type by hot extrusion or rotation, in uneven thickness, in order to improve its bearing capacity and safety, it has to improve blank
Thickness, cause the increase of cost and weight；The utility model primarily serves support by the structure of segmented, axle body 1
Effect, wall thickness can reduce, and load receiving part 2 primarily serves carrying effect, can increase wall thickness, and 2 dimensional accuracy of load receiving part is high, processing
Defect is few, and bearing capacity is stronger；The outer surface of load receiving part 2 and the outer surface of variable diameter auxiliary section 3 constitute tendency axial line, default
The angle of angle, in segmented Trailer car shaft use process, 1 stress of axle body is bent downwardly, load receiving part 2 and variable diameter auxiliary section
3 flush with outer surface improves the stability of axle and the service life of tire；In conclusion the structure using segmented is set
Meter, it is light-weighted simultaneously in entirety, improve the bearing capacity and safety in utilization of axle.
Compared with prior art, the utility model has the following beneficial effects: the structure using segmented designs, axle master
The thickness of body further decreases, and the thickness of load receiving part increases, and size is more uniform, and overall weight reduces, and cost decline is held simultaneously
