Description
Technical field
The utility model relates to auto parts and components, specifically a kind of novel commercial vehicle carriage assembly type crossbeam.
Background technique
Commercial vehicle frame system and frame is that the installation of the transmission parts such as vehicle body, preceding (rear) draft hitch, engine and gearbox is flat
Platform, the active force that above-mentioned component applies is undertaken by vehicle frame, so the rigidity of frame assembly, intensity and vibration characteristics are almost
Determine the intensity, rigidity and vibration characteristics of vehicle entirety.
Horizontal beam action is to be linked together the left and right stringer of vehicle frame to constitute a complete frame.The vehicle frame of early stage is horizontal
Beam function is more single, and the rigidity and intensity of vehicle frame entirety are improved mainly as connection unit.The frame cross developed now is simultaneous
Have multiple functions, some crossbeams need to be as the installation point of engine, radiator and suspension system.
There are mainly two types of structure types for the more crossbeam for having suspension installation point function concurrently of application at present: monoblock type casting is horizontal
Beam, Integral welded crossbeam (mainly thering is the V at both ends to push away support to be welded with intermediate Guan Liang).Both beam structures exist
It is insufficient as follows:
1. integral crossbeam needs to tear open on one integral piece crossbeam once damaging (spot failure typically occurs near suspension interface)
It removes, more renew crossbeam.Above-mentioned maintenance work difficulty is big, time-consuming, leads to maintenance cost height；
2. monoblock type casting beam poor universality needs to cast exploitation new product again according to different frame widths.Separately
Outer monoblock type casting beam casting manufacturability is poor, and new product development die cost is high, and part quality is at high cost greatly；
Although 3. Integral welded crossbeam can by change intermediate tube beam length increase the adaptation of product, both ends
V pushes away support and also easily realizes light-weight design, but its welding quality requires height.The crossbeam for especially having air accumulator function concurrently is mentioning
It is tighter to welding sealing requirements in the case where the gas storage limited volume of confession, need to increase postwelding sealing propertytest technique, it is invisible
Middle increase part manufacturing cost.
Application No. is: a kind of commercial vehicle frame cross assembly of 201721680453 .9, a kind of commercial vehicle frame cross are total
At, including two channel crossbars (1), two channel crossbar (1) slit openings are positioned opposite, two channel crossbar (1) both ends point
It is not connected by cross-beam connecting plate structure I and cross-beam connecting plate structure II with longitudinal beam；Cross-beam connecting plate structure I includes
Cross-beam connecting plate I (2) and cross-beam connecting plate II (3), cross-beam connecting plate I (2) are connected with two channel crossbar (1) tops, horizontal
Beam connecting plate II (3) is connected with two channel crossbar (1) lower parts；Cross-beam connecting plate structure II includes cross-beam connecting plate III (4)
With cross-beam connecting plate IV (5), cross-beam connecting plate III (4) is connected with two channel crossbar (1) tops, cross-beam connecting plate IV (6)
It is connected with two channel crossbar (1) lower parts.The stiffness and intensity for improving entire crossbeam assembly improve the resistance of crossbeam assembly
The ability of deformation.
Although the patent document also uses the package assembly of muti-piece, but more troublesome when use, one is cost increases
Add, the second is V pushes away the installation of support and the installation of splash apron bracket needs separately to process or supplementary features.
A kind of truck frame cross of 201410308184 .8 of application number, the present invention relates to a kind of truck vehicle frame cross
Beam, opening up crossbeam including U-shaped profile, pass through bending at the bottom plate for being fixed on four edges in U-girder bottom
It is set to plate outer side vertical plate I perpendicular to the base plate and I outboard end of vertical plate and vertical with vertical plate I is set to by bending
Vertical plate II, the side of each vertical plate I and crossbeam is mutually fixed.Crossbeam is that its structure of U-shaped structure is simple, is convenient for manufacture,
Bottom surface can be made effectively to bear the pulling force of suspension transmitting the opening up placement of U-shaped crossbeam according to vehicle frame rear portion loading characteristic.
The connecting board structure of vertical plate I, vertical plate II and bottom plate composition can not only guarantee the bonding strength of connecting plate and cross-beam body, but also can
To guarantee the bonding strength of crossbeam and vehicle frame, horizontal depth of beam is substantially reduced, and more meets the assembly demand of pumping installations.
Structure is relatively easy in the patent document, wherein bottom surface can be made effectively to bear the opening up placement of U-shaped crossbeam
The pulling force of suspension transmitting, but the endurance in the directions such as left and right distortion is still suffered from for equalizing type of suspension, so using
When equally there is also limitations.
Summary of the invention
The utility model crossbeam is in order to overcome two kinds of monoblock type casting beam, Integral welded crossbeam structure brings not
Foot, spy propose a kind of novel commercial vehicle carriage assembly type crossbeam.
