Abstract
The utility model relates to a part of an all-electric heavy tractor, in particular to a frame of the all-electric heavy tractor, which is characterized in that the cross sections of left and right longitudinal beams are both provided with a closed box pile, front and back transverse beams respectively penetrates through and are fixedly welded with the left and right longitudinal beams; and the cross sections of the left and the right longitudinal beams are internally provided with horizontally-arranged reinforcing sleeves. For the frame of the all-electric heavy tractor, the cross sections of the left and the right longitudinal beams are designed to be the closed box pile beams instead of the original trough type, thus obviously improving the bearing capacity, impact resistance, torque resistance and bending resistance of the whole frame. The frame of the all-electric heavy tractor has reasonable and simple structure which is a frame structure suitable for the all-electric heavy tractor.
Description
Technical field
The utility model relates to the parts of pure electric heavy type traction car, particularly about a kind of vehicle frame of pure electric heavy type traction car.
Background technology
At present, pure electric heavy type traction car still is a technological gap at home, and the environment low-speed heave-load is made in this turner, impulsive force is big, requires vehicle frame that good bending resistance square and torque resistant performance are arranged.Simultaneously, this technology may be used on other similar working environment vehicles.But, longeron of " groove " type of existing automobile and the load that body frame structure for automotive is not suitable for low-speed heave-load, large impact power thereof, so, the vehicle frame of prior art still can not simply be used as pure electric heavy type traction car.
The utility model content
The purpose of this utility model provides a kind of vehicle frame of pure electric heavy type traction car, has the bending resistance torsional strength and reaches the high vehicle frame of reliability well for pure electric heavy type traction car provides a kind of.
For realizing that this purpose adopts following technical scheme: a kind of vehicle frame of pure electric heavy type traction car, comprise left-right longeron, front and back crossbeam, the transversal surface that it is characterized in that left-right longeron all is set to the osed top box, and the front and back crossbeam is fixed it through left-right longeron and welding respectively; Be provided with horizontal reinforcing sleeve in the left-right longeron box section.
Press the vehicle frame of the pure electric heavy type traction car of this programme enforcement, the transversal surface of left-right longeron is made as the osed top box beam by grooved, improved the performance of vehicle frame single-piece load-carrying capacity, shock resistance, antitorque and bending resistance significantly, the utility model is rational in infrastructure simple and direct, is a kind of body frame structure for automotive that is suitable for pure electric heavy type traction car.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the utility model;
Fig. 2 is the section structure scheme drawing of left-hand stringer.
Weld seam 21,51
Reinforcing sleeve 31 screws 32
The specific embodiment
Be further described in detail in conjunction with the accompanying drawings.The section of the left-right longeron 3,8 of car body is made sealing box-type section as shown in Figure 2 in the present embodiment, because of the section of left-right longeron 3,8 identical, Figure 2 shows that left longeron 3, for relevant parts are installed in vehicle frame, the both sides of left-right longeron are drilled with some screws 32, this technology has reduced the intensity and the rigidity of longeron, for this reason, welded 2 horizontal reinforcing sleeves 31 in left-right longeron is provided with the suitable cross section of screw, reinforcing sleeve 31 has obviously strengthened ability and antitorque and performance bending resistance that frame assembly bears heavy lift.Be to improve vehicle frame single-piece rigidity, with front and back crossbeam 2 and 5 respectively behind left-right longeron 3 and 8 again welding fix it, wherein weld seam is 21,51.The front end of left-right longeron is equipped with bumper arm assembly 1,9 respectively, and the left-right longeron middle part is provided with tubular cross bearer 4, and afterbody is equipped with saddle pillar assembly 6 and tail boom assembly 7.
With the above-mentioned vehicle frame that manufactures and designs, mounting bracket connecting bore position and bumper holder connecting bore position before the attached operator's compartment of left and right sides bumper arm, the attaching of saddle pillar is solid and reliable, and additional strengthening also is the tubular cross bearer welded structure under it, has significantly improved vehicle frame bulk strength and impact resistance.Tail boom assembly integral welding, inner have many places to strengthen with left-right longeron, integrated tail light support and brake the 3rd gas cylinder cradling function, effective simplification structure, cost-cutting.Figure 2 shows that the box-type section of left-right longeron and be set reinforcing sleeve 31 structures in position, hole of longeron, form by rectangle butt welding longeron and reinforcing sleeve.Because the working environment of pure electric heavy type traction car is that low-speed heave-load, impulsive force are big, and electronic dock tractor is because driven by electric energy fully, rolling up of its electric closed-center system (electric capacity) and electrical control equipment, cause the car load deadweight significantly to be risen, this has just had higher requirement to vehicle frame bending resistance square torque resistant performance.Than before double-deck girder work, though the longeron of box type construction has clear superiority on the bending resistance torsional property.But its predetermincd tension that is produced when existing position, longeron hole and fastener connection again causes the beam areal deformation to destroy problem, the utility model adopts the reinforcing sleeve scheme of burying, be about to reinforcing sleeve and longeron one side inside face after the welding of place, position, hole, butt welding is a box beam again, reinforcing sleeve has played supporting role at place, position, hole like this, has improved position, longeron hole fastener bonded assembly intensity and reliability.
Claims (2)
1. the vehicle frame of a pure electric heavy type traction car comprises left-right longeron, front and back crossbeam, it is characterized in that the transversal surface of left-right longeron all is set to the osed top box, and the front and back crossbeam is fixed it through left-right longeron and welding respectively.
2. the vehicle frame of pure electric heavy type traction car as claimed in claim 1 is characterized in that being provided with horizontal reinforcing sleeve in the left-right longeron box section.
