Description

High-strength vehicle vehicle frame
Technical field
The present invention relates to automobile frame technical field, specially automobile frame.
Background technology
Vehicle frame is the tower structure being connected across on automobile tandem axle, is commonly called as crossbeam, is the matrix of automobile.Typically by two Root longeron and several crossbeam compositions, are bearing on wheel via suspension arrangement propons back axle.Vehicle frame must have enough strong Degree and rigidity are with the load bearing automobile and the impact transmitted from wheel.The function of vehicle frame is to support, connect each assembly of automobile, Make each assembly keep relatively correct position, and bear the various load of automobile interior exterior.
Traditional automotive frame and the various external assembling of fixation are all connected using willow connection or welding, this connected mode When occurring coming off or damaging phenomenon, also need the instrument of specialty to help change, have certain limitation, longitudinal beam is peace sometimes Filling some parts or assembly, needing to hole on longeron, this some holes can lead to stress concentration, thus reducing the intensity of longitudinal beam And lead to ftracture.
Content of the invention
It is an object of the invention to provide high-strength vehicle vehicle frame, to solve the traditional vapour proposing in above-mentioned background technology Crossbeam and the various external assembling of fixation are all connected using willow connection or welding, and this connected mode is occurring coming off or damaging During phenomenon, also need the instrument of specialty to help change, have certain limitation, longitudinal beam is to install some parts or total sometimes Become, need to hole on longeron, this some holes can lead to stress concentration, thus reducing the intensity of longitudinal beam and leading to that ftractures to ask Topic.
For achieving the above object, the present invention provides following technical scheme:High-strength vehicle vehicle frame, vertical including left longeron, the right side Beam, first crossbeam, second cross beam, the 3rd crossbeam, the 4th crossbeam, the 5th crossbeam, the 6th crossbeam, reinforcement, stiffening ring, crossbeam are even Fishplate bar and bolt, are connected by crossbeam between described left longeron and right vertical beam, after the past between described left longeron and right vertical beam It is sequentially provided with first crossbeam, second cross beam, the 3rd crossbeam, the 4th crossbeam, the 5th crossbeam and the 6th crossbeam, described left longeron and the right side Longeron inwall is provided with reinforcement, described first crossbeam, second cross beam, the 3rd crossbeam, the 4th crossbeam, the 5th crossbeam and the 6th The circular hole opening up on crossbeam is provided with stiffening ring, described first crossbeam, second cross beam, the 3rd crossbeam, the 4th crossbeam, the 5th horizontal stroke Beam and the 6th crossbeam are all connected by bolt thread between left longeron and right vertical beam, described first crossbeam, second cross beam, the 3rd Crossbeam, the 4th crossbeam, the 5th crossbeam and the 6th crossbeam are provided with cross-beam connecting plate with left longeron and right vertical beam junction.
Preferably, described bolt using apply must firm technology bolt.
Preferably, the installing hole described left longeron and right vertical beam opening up is provided with stiffening ring.
Preferably, the spacing of described 3rd crossbeam and the 4th crossbeam is more than the spacing between other crossbeams.
Preferably, described left longeron, right vertical beam, first crossbeam, second cross beam, the 3rd crossbeam, the 4th crossbeam, the 5th crossbeam Collectively constitute automobile frame with the 6th crossbeam, and automobile frame adopts hot-rolled low-alloy high-strength steel material.
Compared with prior art, the invention has the beneficial effects as follows:This high-strength vehicle vehicle frame changes traditional Liu Ding vehicle frame, adopts With bolt fastening, this automobile frame using apply must firm technology bolt, due to bolt manufacture and design all adopt more special Technique and instrument, are comparing with normal screws and traditional rivet, its shock-proof check performance is more preferable, this skill simultaneously The nut of art does not need the locking element of any assisted class, and traditional Liu Ding fixes vehicle frame, can be potentially encountered Liu Ding and come off or damage Bad phenomenon, but because changing of rivet needs just can complete by the help of professional tool, so also there being certain limitation Property, but if using the fixing vehicle frame of bolt, once finding there is the situation coming off or damaging, can be complete by simple instrument Become the work changed, it is more convenient to use, not only shock resistance is more preferably, easy to use for bolt, and bolt also has the anti-of uniqueness Multiple usability, after multiple demounting bolt, still will not destroy the normal work of bolt, install certain sometimes on longeron A little parts or assembly, need to hole on longeron, this some holes can lead to stress concentration, thus reducing the intensity of longitudinal beam and leading Cause cracking, the installation in the hole that this automobile frame opens up in longeron is provided with stiffening ring, installing hole is reinforced, reduce longeron and open The probability split, the spacing that two crossbeam spacing being arranged on central frame beam are more than between other crossbeams is it is ensured that vehicle exists The torsional forces producing in transportation effectively discharges, and vehicle frame is the basic element of character of whole automobile, and it subjects loaded whole Quality, and subject the various power passing to it or moment, it is whole whether vehicle frame has enough intensity, rigidity, flexibility to directly affect The service life of car, under conditions of not increasing wall thickness, longeron inwall arranges reinforcement to this vehicle frame, improves the carrying energy of vehicle frame Power, reduces the deadweight of longitudinal beam, reduces fuel consumption, has saved use cost, and automobile frame uses hot-rolled low-alloy High-strength steel sheet, on the premise of ensureing rigidity, can reduce the thickness of steel plate, alleviate the weight of automobile frame, improve The bearing capacity of automobile frame, extends the service life of automobile, and the bending resistance of this hot-rolled low-alloy high-strength steel plate and antitorque strong Degree is high, reduces the probability that vehicle frame is subject to lead under impact loading rupture.
