Have the dump Truck Frame of subframe function concurrently
Technical field
The present invention relates to automobile chassis frame, particularly a kind of dump Truck Frame that has the subframe function concurrently.
Background technology
Present dumping truck adopts subframe, is used for installing the longeron of packing case lifting oil cylinder, container trip shaft bearing and supporting container, and requires subframe to have enough strength and stiffness.Therefore must make subframe with more material with certain mass, make it have higher productive costs, and due to its curb mass that has increased car load, be unfavorable for the economy of using.
Summary of the invention
The present invention proposes a kind of dump Truck Frame that has the subframe function concurrently, and it can overcome the problems referred to above.
This dump Truck Frame that has the subframe function concurrently provided by the invention, the left and right longeron of vehicle frame is pressed into the channel-section rail of unequal section with special-purpose beam steel plate, in vehicle frame left and right longeron stage casing and the stressed larger part of back segment, the flute profile strength beam of the unequal section that the useful special-purpose beam steel plate of side riveted joint within it is compressing, at the left and right longeron installation hydraulic ram of vehicle frame place, hydraulic ram bracket reinforcing plate that is pressed into flute profile with special-purpose beam steel plate of side riveted joint within it.left at vehicle frame, on right vertical beam, adopt successively from front to back riveting method to be connected with the parts that automobile chassis frame should have: frame front cross beam, front suspension steel spring bearing, the vehicle frame second cross beam, engine front suspension transverse member, front shock absorber upper bracket, rear suspension support for engine, front suspension hinge of leaf spring bearing, the 3rd cross-beam connecting plate, vehicle frame the 3rd crossbeam, the four or five cross-beam connecting plate, vehicle frame the 4th crossbeam, rear suspension steel spring bearing, rear suspension additional leaf spring front frame, rear suspension additional leaf spring after poppet, the four or five cross-beam connecting plate, vehicle frame the 5th crossbeam, rear suspension steel spring sliding bearing.Riveted joint container of dump truck guide positioning plate on the left and right longeron of vehicle frame, the guide positioning plate of vehicle frame arranged on left and right sides forms the v character form structure, when falling after rise, container can play directional tagging to the container longeron, guaranteed that preferably container falls accuracy of positioning, the service life of having improved the parts such as capacity of the tipping body trip shaft after rise.At the inboard soldering fluid compressing cylinder of left and right hydraulic ram bracket reinforcing plate support; Weld respectively the trip shaft brace panel that a steel plate is made in the left and right longeron back segment of vehicle frame inboard, make container trip shaft supporting position form box-shaped, make it have enough Rigidity and strengths, and at its formed box-shaped top welding one container trip shaft axle sleeve; Weld respectively a steel brace panel at the left and right longeron rearmost end of vehicle frame; Trip shaft brace panel bottom in the inboard welding of the back segment of the left and right longeron of vehicle frame is welded with the after cross member that rectangular steel tube is made; Weld wheel support between the 5th crossbeam and after cross member.
Because this vehicle frame not only has the needed parts of common cargo vehicle frame, and have the major part that dump truck auxiliary frame need be installed, as: hydraulic ram support, the parts such as container trip shaft axle sleeve, container of dump truck guide positioning plate.Not only can realize the function of common cargo vehicle frame, and have the function of dump truck auxiliary frame concurrently, make and adopt the dumping truck of this structure to need not subframe, can reduce the use of material and the curb mass of car load.Thereby reduce production costs, and greatly be conducive to its usage economy.Can be widely used in dumping truck, particularly in, light-duty dumping truck.
