Abstract
The utility model discloses a connecting structure for a back support beam and longerons of a driving cab, which mainly comprises the back support beam (1) of the driving cab and vehicle frame longerons (2) on two sides of the back support beam (1) of the driving cab, and is characterized in that connecting plates (3) are respectively fixed on two sides of the back support beam (1) of the driving cab, a connecting seat (4) is further fixed on each connecting plate (3), and the connecting seats (4) are respectively and fixedly connected with the breadths (5) of the vehicle frame longerons (2). The integral structure of the utility model is very simple, and the back support beam of the driving cab is in indirect connection with the upper wing surfaces of the vehicle frame longerons, thereby efficiently avoiding the defect of stress concentration, and efficiently preventing a main longeron from fracture.
Description
Technical field
The utility model relates to a kind of connection structure, specifically is meant support beam and longeron connection structure behind a kind of operator's compartment.
Background technology
At present, engineering with the operator's compartment of dumping car after support beam all adopt traditional riveted joint mode when being connected with chassis side rail with Connection Block, be when support beam is connected with chassis side rail behind the operator's compartment, respectively be provided with 4 pieces of rivets at vehicle frame left-right longeron upper limb, when Connection Block was connected with chassis side rail, this Connection Block bottom then was connected by 3 pieces of rivets with the chassis side rail breadth.Because support beam is in the compartment front end and is positioned at the middle part of vehicle frame behind the operator's compartment, when vehicle for a long time in the building site, when moving in the relatively poor environment of condition of road surfaces such as mine, moment of flexure and moment of torsion maximum that this vehicle frame middle part is born, stress concentration appearred in support beam rivet junction after these two kinds of moment stacks will cause longeron upper limb and operator's compartment, very easily cause producing herein endurance crack, and this crackle is in case produce, just can stretch to longeron breadth edge rapidly along rivet hole, finally cause the main longitudinal grider fracture of vehicle frame both sides, the connection mode of support beam and chassis side rail can not well overcome the defective of main longitudinal grider fracture behind therefore present this operator's compartment, can not be well by promotion and application.
The utility model content
The purpose of this utility model is to overcome the defective that very easily causes the main longitudinal grider fracture when support beam and chassis side rail adopt the tradition riveted joint behind the present operator's compartment, provide a kind of and not only implement conveniently, and can also effectively prevent support beam and longeron connection structure behind the operator's compartment of main longitudinal grider fracture.
The purpose of this utility model is achieved through the following technical solutions: support beam and longeron connection structure behind a kind of operator's compartment, main by support beam behind the operator's compartment and after being positioned at this operator's compartment the chassis side rail of support beam both sides form, the dual-side of support beam is fixed with connecting panel respectively behind this operator's compartment, and also be fixed with Connection Block on each connecting panel, described Connection Block is fixedly linked with the breadth of chassis side rail respectively.
For the ease of fixing, all adopt rivet to be connected between support beam and the connecting panel and between the breadth of Connection Block and chassis side rail behind the described operator's compartment.
In order better to realize the utility model, can adopt riveted joint or welding between described connecting panel and the Connection Block.
Further, described connecting panel and Connection Block all are positioned at the inside of chassis side rail, and leave the gap between the lateral end panel of support beam behind the top airfoil of chassis side rail and the operator's compartment.
The utility model compared with prior art has following advantage and beneficial effect:
(1) integral structure of the present utility model is comparatively simple, and support beam directly is not connected with the top airfoil of chassis side rail behind the operator's compartment, and therefore the energy actv. is avoided the defective of stress concentration.
(2) the utility model also is provided with connecting panel between support beam behind the operator's compartment and Connection Block, therefore can further increase its switching performance.
Therefore (3) the utility model no longer is provided with rivet hole on the top airfoil of chassis side rail, can actv. prevents that the edge of the endurance crack that produces in this rivet hole place from stretching, and then can effectively prevent the fracture of main longitudinal grider.
Description of drawings
Fig. 1 for existing operator's compartment after connection structure scheme drawing between support beam and the longeron.
Fig. 2 is the connection structure scheme drawing between support beam and the longeron behind the operator's compartment of the present utility model.
The specific embodiment
Below in conjunction with embodiment the utility model is described in further detail, but embodiment of the present utility model is not limited thereto.
Embodiment
As shown in Figure 1, the dual-side of support beam 1 directly adopts rivets 6 to captive joint with the top airfoil 7 of chassis side rail 2 behind traditional operator's compartment, be arranged on chassis side rail 2 operator's compartment inner and that be connected to a fixed with the breadth 5 of chassis side rail 2 simultaneously after support beam Connection Block 8 also directly be fixedly linked by the side of support beam 1 behind rivet 6 and the operator's compartment.At this moment, support beam Connection Block 8 also is close to the top airfoil 7 of this chassis side rail 2 behind this operator's compartment.
As shown in Figure 2, the dual-side of support beam 1 has been fixedly coupled connecting panel 3 by rivet 6 respectively behind the operator's compartment of the present utility model.Simultaneously, also be fixedly coupled Connection Block 4, and the side of this Connection Block 4 is connected to a fixed by the breadth 5 of rivet 6 with chassis side rail 2 also by rivet 6 in the lower end of each connecting panel 3.In order to meet the different needs, can also adopt the connection mode of welding between this Connection Block 4 and the connecting panel 3.
In order to ensure result of use, behind the operator's compartment side upper surface of support beam 1 need and the top airfoil 7 of chassis side rail 2 between leave certain clearance.Because this chassis side rail 2 constitutes " U " font together by breadth 5, top airfoil 7 and lower aerofoil, when therefore connecting, the side of support beam 1 all is positioned at its inside behind whole Connection Block 4, connecting panel 3 and the operator's compartment, promptly is somebody's turn to do the inside of " U " font.Simultaneously, also leave certain clearance between the lower surface of the lower aerofoil of this chassis side rail 2 and Connection Block 4.
Because the top airfoil 7 of this chassis side rail 2 no longer is connected with support beam 1 behind the operator's compartment, therefore on this top airfoil 7, no longer is provided with rivet hole, thereby can actv. prevents that stress is concentrated and the edge of the endurance crack that produced is herein stretched.
As mentioned above, just can well realize the utility model.
