Description

A kind of vehicle frame

Technical field

This utility model relates to the vehicle frame of automobile, is specially a kind of vehicle frame.

Background technology

Automobile frame is typically made up of longitudinal and cross beam.

Its form mainly has edge-beam type and cross beam type two kinds, and straight frame is by two longerons being positioned at both sides and some Crossbeam forms, and with riveting or welding, longeron and crossbeam is connected into firm braced frame.

Longeron is generally stamped to form with low alloy steel plate, and section configuration is generally grooved, and also have does z-shape or box. The requirement that difference according to type of motor car and structure are arranged, longeron can make bending in horizontal plane or in vertical plane, with And equal section or non-equal section.

Crossbeam is not only used to ensure the torsional rigidity of vehicle frame and bear longitudinal loading, but also can support the master on automobile Want parts.Generally load-carrying vehicle has 5～6 crossbeams, the most more.

Being structurally characterized in that of straight frame is easily installed driver's cabin, compartment and some special equipments and arranges that other are total Become, be conducive to repacking modification of vehicle and development multi items automobile, be therefore widely used on cargo vehicle and most of special car.

Longeron for truck typically uses the structure of multiple grooved superposition to increase its load-bearing, and such cost is relatively High or new structure is accomplished by for a kind of vehicle frame.

Summary of the invention

This utility model, in order to manufacture one, makes automobile from possessing lifting set, ensures that automobile is at hoisting operation simultaneously Time possess good stability and traffic safety, special a kind of vehicle frame is proposed.

It is that a kind of vehicle frame, including frame body, vehicle frame is positioned at dual-side by two for this technical solution of the utility model Longeron and some crossbeams composition, with riveting or welding, longeron and crossbeam are connected into firm braced frame, its It is characterised by: on the lateral surface of described two longerons, be provided with reinforcement bag girder construction, is formed as longeron entirely surrounding or local Surround or Semi surrounding type structure.

Further it is improved by: described full structure of surrounding is that disjunctor trench structure strengthens Bao Liang, disjunctor trench structure The material strengthening the selection of bag beam is: DL510；Thickness range: 5～12mm；Trench structure altitude range: 262～318mm；Grooved Upper and lower width range: 75～108mm；Overall length: 2330～11850mm.

Further it is improved by: it is that upper and lower pair of L type is strengthened surrounding that described local surrounds structure, and at longeron Side forms gap by upper and lower pair of L type docking, and the material of selection is: DL510；Thickness range: 5～12mm；L-type height Scope: 101～154mm；L-type width range: 75～108mm；Overall length: 330～11850mm.

Further it is improved by: Semi surrounding type structure is that L-type increases reinforcement bag girder construction, is by the bottom surface of longeron and side Face forms Semi surrounding type structure, and increases the vertical edges of reinforcement structure higher than vertical depth of beam, the material of selection by L type It is: DL510；Thickness range: 5～12mm；L-type altitude range: 336～489mm；L-type width range: 75～108mm；Overall length: 2000～9570mm.

Further it is improved by: upper and lower pair of L type docking forms gap≤10mm, forms expansion joint.

Beneficial effect:

In this utility model, the lateral surface of two longerons is provided with reinforcement bag girder construction, be formed as longeron entirely surrounding or Local surrounds or the structure of Semi surrounding type.While longeron is played booster action, also ensure that automobile is when hoisting operation Possess good stability and traffic safety.

Disjunctor trench structure strengthens bag girder construction feature: whole former longitudinal beam is strengthened bag beam by trench structure and wrapped completely Wrapping up in, intensity is greatly enhanced, and is suitable for installation and the use of medium-sized loop wheel machine.

Upper and lower double L-shaped reinforcement bag girder construction feature, upper and lower increase L-type steel, between Bao Liang, reserved 10mm expansion joint, i.e. increases Add the bending strength of vehicle frame, in turn ensure that the toughness of vehicle frame, the installation of low tonnage truck-mounted crane and use in being suitable for.

Semi surrounding type structure is that L-type increases reinforcement bag girder construction feature: can be tight with subframe by main car frame in installation process Thickly combine, effectively increase the rigidity of truck with loading crane chassis special, be suitable for the peace of large-tonnage truck-mounted crane Dress and use.
