Abstract
The utility model discloses a vehicle frame of a vehicle transport vehicle with a middle-placed shaft, which comprises two longitudinal beams, wherein a cross beam is arranged between the two longitudinal beams, and frames are arranged at two ends of the cross beam; the front ends of the two longitudinal beams are bent towards the center line of the frame and are intersected at the front end of the frame; the middle part of the longitudinal beam is bent upwards, the upper wing plate of the longitudinal beam at the bent part extends to the lower wing plate of the longitudinal beam, and the bent part is provided with a web plate reinforcing plate; through the utility model discloses an use, can reduce the focus height at both ends around the frame, improve the stability of traveling of vehicle, also improved the intensity of frame simultaneously, prevent the frame fracture.
Description
The technical field is as follows:
the utility model relates to a special-purpose vehicle technical field, specifically say and put a vehicle transport vechicle frame in.
Background art:
at present, the front end of a frame of a vehicle transport vehicle with a middle-arranged shaft is connected with a tractor by a draw bar, the torsional rigidity of the frame is lower, and the running stability of the vehicle is poorer; the upper wing plate of the longitudinal beam is of an integral structure from front to back, and the bending part of the longitudinal beam has stress concentration, so that the strength of the longitudinal beam is insufficient; in general, in order to increase the strength of the side member, the thickness of the wing plate or the web plate needs to be increased, which results in a large weight of the vehicle.
The utility model has the following contents:
the utility model aims to overcome the defects of the prior art and provide a vehicle frame of a vehicle with a middle-arranged axle; the main poor and not enough problem of intensity of frame stability of current put a vehicle transport vechicle in solving.
The technical scheme of the utility model is that: a vehicle frame of a vehicle with a middle-mounted shaft is characterized by comprising two longitudinal beams, wherein the two longitudinal beams are bilaterally symmetrical, a cross beam is vertically arranged between the two longitudinal beams, and frames are arranged at two ends of the cross beam; the front ends of the two longitudinal beams are bent towards the center line of the frame and are connected with the front end of the frame in a crossed manner; the middle part of the longitudinal beam is bent upwards.
Furthermore, the longitudinal beam consists of a front upper wing plate, a middle upper wing plate, a rear upper wing plate, a lower wing plate and a web plate; the lower wing plate is arranged at the lower end of the web plate, and the front upper wing plate, the middle upper wing plate and the rear upper wing plate are sequentially arranged at the upper end of the web plate; the front upper wing plate and the rear upper wing plate extend to the lower wing plate and are fixedly connected.
Furthermore, a front longitudinal beam reinforcing plate is arranged between the front upper wing plate and the middle and upper wing plate, a rear longitudinal beam reinforcing plate is arranged between the rear upper wing plate and the middle and upper wing plate, and the rear longitudinal beam reinforcing plate and the front longitudinal beam reinforcing plate are both parallel to the web plate and fixed at the upward bending part in the middle of the longitudinal beam.
Compared with the prior art, a put a vehicle transport vechicle frame and have following positive effect:
1. the front ends of the two longitudinal beams are bent inwards, and the front ends form a triangular structure, so that the torsional rigidity of the frame is high, and the vehicle is more stable;
2. the upper wing plate is of a segmented structure, extends to the lower wing plate from the inside of the longitudinal beam, and is additionally provided with the longitudinal beam reinforcing plate, so that the strength of the longitudinal beam and the whole frame is improved, and the self weight of the vehicle is reduced.
Description of the drawings:
fig. 1 is a schematic structural diagram of the present invention;
fig. 2 is a schematic structural view of the longitudinal beam of the present invention;
3 fig. 3 3 3 is 3 a 3 sectional 3 view 3 a 3- 3 a 3 of 3 fig. 3 2 3. 3
The specific implementation mode is as follows:
for a better understanding and practice, the following detailed description of the embodiments is given in conjunction with the accompanying drawings; the examples are given solely for the purpose of illustration and are not intended to limit the scope of the invention.
Example 1, referring to fig. 1, 2 and 3, a lower wing plate 16 is welded at the lower end of a web plate 17, and a front upper wing plate 11, a middle upper wing plate 12 and a rear upper wing plate 13 are respectively welded at the upper end of the web plate 17 in sequence, so that the front upper wing plate 11 and the rear upper wing plate 13 are extended to the lower wing plate 16 and welded; a front longitudinal beam reinforcing plate 15 is welded between the front upper wing plate 11 and the middle upper wing plate 12, a rear longitudinal beam reinforcing plate 14 is welded between the rear upper wing plate 13 and the middle upper wing plate 12, the rear longitudinal beam reinforcing plate 14 and the front longitudinal beam reinforcing plate 15 are welded at the upward bending part of the longitudinal beam in parallel to the web 17, the longitudinal beam 1 is formed by assembly welding, and the middle part of the longitudinal beam 1 is bent upwards; welding the front end intersection of two longitudinal beams 1 which are symmetrical left and right, and enabling the rest parts to be parallel to each other; a cross beam 2 is vertically arranged between the two longitudinal beams 1, and frames 3 are fixedly arranged at two ends of the cross beam 2; form the utility model discloses a put a vehicle transport vechicle frame in.
The above embodiment 1 is only used for explaining the present invention, and it does not limit the protection scope of the present invention. All the equivalent structural changes made by applying the contents of the specification and the drawings of the utility model fall into the protection scope of the utility model.
