Abstract
The utility model discloses a tube-type front suspension rear bow beam comprising a tube-type cross beam (1) and a connecting arm (2) which is fixed at both ends of the tube-type cross beam (1). The tube-type cross beam (1) and the connecting arm (2) form a U shape, and the tube-type cross beam (1) comprises at least two round tubes which share the same horizontal plane and are arranged side by side. The utility model ensures the structural strength of the vehicle frame assembly as well as the installation and use reliability of the power transmission system. As the torsional rigidity of the vehicle frame assembly is enhanced, when in use on a cross-country road or on a bumpy construction site, the overloaded vehicle can enable the strong impact force thereon caused by the poor road to be uniformly transmitted to the vehicle frame, thereby avoiding the frame side member from being damaged due to excessive torsion and deformation of the vehicle frame.
Description
Technical field
The utility model belongs to camber beam behind a kind of automobile front suspension, specifically, is camber beam behind a kind of tubular type front suspension that is used for heavy motor vehicle.
Background technology
At present, adopt the front suspension part of the universal wheel goods carrying vehicle of longitudinal spring plate structure both at home and abroad, because of the radiator of power drive system, driving engine, power-transfer clutch, change-speed box etc., be installed between the left and right side bar of top vehicle frame, frame assembly backward after change-speed box, all can not be arranged crossbeam from first crossbeam.For guaranteeing rigidity of frame, prevent in the vehicle ', because of the bad torsional deflection of road when excessive to vehicle frame, to vehicle frame and power, the installation of driving system and the influence of reliability of service, common rear end in the front suspension steel spring, adopt steel plate punching press or welded crossbeam, left and right frame side member is coupled together, with the lateral deformation of restriction frame assembly.The after cross member of the front suspension of general goods carrying vehicle can only be designed to down curved planform.Goods carrying vehicle that under the relatively poor situation of the road conditions of being everlasting, uses and general dumping truck, fracture defect often takes place in its front suspension after cross member, and after repairing welding, very fast the appearance again ruptures.Some heavy-duty tippers simply become a flat type osed top box type construction to beam design, cause main car frame generation phenomenon of rupture on the contrary.That is to say that the front suspension after cross member must have certain stiffness, simultaneously, also enough toughness should be arranged, could guarantee that vehicle normally uses.Existing front suspension after cross member all can not satisfy such rigidity and toughness simultaneously.
The utility model content
Technical problem to be solved in the utility model is to provide camber beam behind a kind of rigidity and all good tubular type front suspensions that is used for heavy motor vehicle of toughness.
The technical solution of the utility model is as follows: camber beam behind a kind of tubular type front suspension, and its key is: camber beam is fixedly coupled arm by tubular type crossbeam and tubular type crossbeam two ends and forms behind the described tubular type front suspension, and described tubular type crossbeam and connecting arm constitute " U " font.Described tubular type crossbeam is made of at same horizontal surface side by side at least two pipes.Double hose front suspension after cross member, comparing and adopting casting is that the crossbeam of one has better antitorque commentaries on classics performance, can bear multidirectional reverse stress by failure-free, guarantees the stiffness of frame assembly.Can guarantee have under enough gap conditions, maximum raising terrain clearance with power system.And alleviated weight.
Above-mentioned tubular type crossbeam links to each other with the connecting arm bolt by the connecting panel that both ends of the surface are provided with.
Be provided with by reinforced rib between above-mentioned tubular type crossbeam and the connecting panel.
The above-mentioned connecting arm first half is connected with automobile longitudinal girder, and this connecting arm first half forms and coats automobile longitudinal girder outer side edges and base " L " the type link span, should " L " type link span lower end has a breach that leaf spring is installed.The leaf spring after poppet and the camber beam connecting arm that connect vehicle frame are cast into one, and direct and leaf spring connects as one.
Beneficial effect: the utility model has guaranteed the structural strength of frame assembly and installation, the reliability of service of power drive system.Strengthen the torsional stiffness of frame assembly, make automobile on cross-country road or rugged building site during operation, can be delivered to more uniformly on the vehicle frame with abominable road to the powerful impulsive force that overloaded vehicle causes, prevent to cause frame side member to damage because of the excessive torsional deflection of vehicle frame.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the assembling scheme drawing of the utility model and vehicle frame, leaf spring.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in Figure 1 and Figure 2, camber beam behind the tubular type front suspension is fixedly coupled arm 2 by tubular type crossbeam 1 and tubular type crossbeam 1 two ends and forms, and described tubular type crossbeam 1 and connecting arm 2 constitute " U " font.Described tubular type crossbeam 1 is made of at same horizontal surface side by side at least two pipes.The connecting panel 1a that above-mentioned tubular type crossbeam 1 is provided with by both ends of the surface and connecting arm 2 link to each other through bolt.Be provided with reinforced rib 1b between above-mentioned tubular type crossbeam 1 and the connecting panel 1a.Above-mentioned connecting arm 2 first halves are connected with automobile longitudinal girder 3, and these connecting arm 2 first halves form " L " type link span 2a that coats automobile longitudinal girder 3 outer side edges and base." L " type link span 2a and automobile longitudinal girder 3 are bolted to connection, and should have the breach that leaf spring 4 is installed in " L " type link span 2a lower end.The two side has mounting hole in this breach, and leaf spring 4 attaching partss are positioned at this breach, connect through minor axis.Leaf spring 4 is supported by the vehicle bridge 5 of below.
Claims (4)
1, camber beam behind a kind of tubular type front suspension, it is characterized in that: camber beam is fixedly coupled arm (2) by tubular type crossbeam (1) and tubular type crossbeam (1) two ends and forms behind the described tubular type front suspension, described tubular type crossbeam (1) and connecting arm (2) constitute " U " font, and described tubular type crossbeam (1) is made of at same horizontal surface side by side at least two pipes.
2, according to camber beam behind the described tubular type front suspension of claim 1, it is characterized in that: described tubular type crossbeam (1) is fixedly linked with connecting arm (2) lower end bolt by the connecting panel (1a) that both ends of the surface are provided with.
3, according to camber beam behind the described tubular type front suspension of claim 2, it is characterized in that: be provided with reinforced rib (1b) between described tubular type crossbeam (1) and the connecting panel (1a).
