Abstract
The invention provides a mounting and supporting device for automobiles. A cross beam of the mounting and supporting device is curved, the cross beam, a first front overhang supporting seat 4 and a second front overhang supporting seat form a non-right-angled triangle so as to increase torsional rigidity and a structure transmission area of the whole automobile and eliminate stress concentration. The torsional rigidity of the whole automobile is increased by about 5%, and stability of the whole automobile is improved.
Description
Technical field
The present invention relates to automobile, relate in particular to the fittable slackening device of automobile.
Background technology
Automobile has front overhang and supports component; Front overhang supports component and is positioned at the chassis bottom; Front overhang supports component and is installed on the fittable slackening device of automobile, and is as shown in Figure 1, and the fittable slackening device of automobile comprises crossbeam 101, left front longeron 102, right front longeron 103, the first front overhang bearing 104, the second front overhang bearing 105; Crossbeam 101 is a straight tube; Left front longeron 102 links to each other with crossbeam 101 respectively with right front longeron 103, and the second front overhang bearing 105 links to each other with crossbeam 101 with left front longeron 102 respectively, and the first front overhang bearing 104 links to each other with crossbeam 101 with right front longeron 103 respectively.Because crossbeam 101 is a straight tube, so after causing the first front overhang bearing 104 and the second front overhang bearing 105 and straight tube linking to each other, make the car load torsional stiffness not enough.
Summary of the invention
In order to solve the problems of the prior art, the invention provides a kind of fittable slackening device of automobile.
The invention provides a kind of fittable slackening device of automobile; Comprise crossbeam, left front longeron, right front longeron, the first front overhang bearing, the second front overhang bearing; Said crossbeam is linked to each other successively by first connection pipe, second connection pipe, the 3rd connection pipe, the 4th connection pipe, the 5th connection pipe and constitutes; Said first connection pipe and said second connection pipe are connected to form first angle; Said second connection pipe and said the 3rd connection pipe form second angle, and said the 3rd connection pipe and said the 4th connection pipe form angular, and said the 4th connection pipe and said the 5th connection pipe form the 4th angle; Said first angle is identical with said the 4th angle, and said second angle is identical with said angular, and said first angle and said second angle are the obtuse angle; Said left front longeron links to each other with said the 5th connection pipe; Said right front longeron links to each other with first connection pipe; The first front overhang bearing links to each other with said second connection pipe with right front longeron respectively, and the said second front overhang bearing links to each other with said the 4th connection pipe with left front longeron respectively.
As further improvement of the present invention, said first front overhang bearing and the said second connection pipe weld together.
As further improvement of the present invention, said second front overhang bearing and said the 4th connection pipe weld together.
As further improvement of the present invention, said first front overhang bearing and said right front longeron are through bolted connection together.
As further improvement of the present invention, said second front overhang bearing and said left front longeron are through bolted connection together.
The invention has the beneficial effects as follows: crossbeam of the present invention is curved shape, and the crossbeam and the first front overhang bearing 4 and the second front overhang bearing form the on-right angle triangle, improves car load torsional stiffness and structure power transmission area, and it is concentrated to eliminate stress; It is about 5% to improve the torsional stiffness of car load, improves whole vehicle stability.

Fig. 3 is that the present invention is equipped with the fittable slackening device structural representation that front overhang supports component.
The specific embodiment
Extremely shown in Figure 3 like Fig. 2; The invention discloses a kind of fittable slackening device of automobile; Comprise crossbeam 1, left front longeron 2, right front longeron 3, the first front overhang bearing 4, the second front overhang bearing 5; Said crossbeam 1 is linked to each other successively and is constituted by first connection pipe 11, second connection pipe 12, the 3rd connection pipe 13, the 4th connection pipe 14, the 5th connection pipe 15, and said first connection pipe 11 is connected to form first angle with said second connection pipe 12, and said second connection pipe 12 forms second angle with said the 3rd connection pipe 13; Said the 3rd connection pipe 13 forms angular with said the 4th connection pipe 14, and said the 4th connection pipe 14 forms the 4th angle with said the 5th connection pipe 15; Said first angle is identical with said the 4th angle, and said second angle is identical with said angular, and said first angle and said second angle are the obtuse angle; Said left front longeron 2 links to each other with said the 5th connection pipe 15; Said right front longeron 3 links to each other with first connection pipe 11; The first front overhang bearing 4 links to each other with said second connection pipe 12 with right front longeron 3 respectively, and the said second front overhang bearing 5 links to each other with said the 4th connection pipe 14 with left front longeron 2 respectively.
The said first front overhang bearing 4 and said second connection pipe, 12 weld togethers.The said second front overhang bearing 5 and said the 4th connection pipe 14 weld togethers.
The said first front overhang bearing 4 passes through bolted connection together with said right front longeron 3.The said second front overhang bearing 5 passes through bolted connection together with said left front longeron 2.
Front overhang of the prior art supports component and links to each other with longeron with crossbeam respectively, and it is two that front overhang supports the component attachment face, and the general assembly bolt is prone to decay, stability is not enough.In order to address the above problem, this fittable slackening device comprises that also first front overhang supports component 9 and second front overhang supports component 10, and this first front overhang supports component 9 and links to each other with the first front overhang bearing 4, and this second front overhang supports component 10 and links to each other with the second front overhang bearing 5.Because first front overhang supports component 9 and is installed on the first front overhang bearing, 4 these attachment faces, thus the attachment face that cooperates reduced, thus improve the stability of making.
Fittable slackening device of the present invention solves and supports component hold-down bolt torsion attenuation problem; Reduce to support attachment point stress concentration behind the component; The face of weld of increase and longeron, the stress of dispersion part, the durability of raising part.
Above content is to combine concrete preferred implementation to the further explain that the present invention did, and can not assert that practical implementation of the present invention is confined to these explanations.For the those of ordinary skill of technical field under the present invention, under the prerequisite that does not break away from the present invention's design, can also make some simple deduction or replace, all should be regarded as belonging to protection scope of the present invention.
