Embodiment
A kind of embodiment of rear overhang swing arm crossbeam of the present invention is made with reference to the accompanying drawings and examples
It is described in further detail.Following examples are used to illustrate the present invention, but are not limited to the scope of the present invention.
As Figure 1-5, a kind of rear overhang swing arm crossbeam of the invention, including swing arm body 1, crossbeam 3,
First reinforcing mechanisms 6,7, two the first swing arm mounting brackets 4 of the second reinforcing mechanisms and two second pendulum
Arm mounting bracket 5, the both ends of crossbeam 3 are Y shape prong, and the both ends of crossbeam 3 are vertical with two respectively
Beam 2 connects, and first reinforcing mechanisms 6 and second reinforcing mechanisms 7 are separately positioned on the crossbeam
3 and two link positions of longeron 2 at, first swing arm peace is provided with first reinforcing mechanisms 6
Support 4 and second swing arm mounting bracket 5 are filled, one the is provided with second reinforcing mechanisms 7
One swing arm mounting bracket 4 and second swing arm mounting bracket 5, described two second swing arm mounting brackets
5 are arranged on two inner sides of the first swing arm mounting bracket 4, two first swing arm mounting brackets 4 and two
It is fixedly connected on individual second swing arm mounting bracket 5 with the swing arm body 1.So, the horizontal stroke
The both ends of beam 3 are Y shape prong, when swing arm body 1 is hung on crossbeam 3, the stress of crossbeam 3, due to horizontal stroke
The both ends of beam 3 are Y shape prong, and crossbeam 3 is fixedly connected with area increase with longeron 2, it is ensured that crossbeam
3 bonding strength, no matter in addition, crossbeam 3 from which side stress, the power suffered by it can be from
Middle part is spread to end, and due to end Y shape prong, suffered power can obtain good in transmittance process
Good is scattered, in terms of existing technologies the advantages of be:The overall rigidity of crossbeam 3 is improved, after raising
The Static stiffness for the arm installation site that dangles, handling, the comfortableness of driving are improved, is increased the service life.
As shown in Figures 1 to 5, a kind of rear overhang swing arm crossbeam of the invention, in previously described technical side
It can also be on the basis of case:The height of the crossbeam 3 is with the crossbeam 3 away from first reinforcing mechanisms
6 or second reinforcing mechanisms 7 vertical range ratio be 8:7.So, the reinforcing mechanisms of crossbeam 3 and first
6 and second reinforcing mechanisms 7 formed double-decker, and the height ratio of the double-decker formed be 8:7,
Due to being double-decker, the local strength of the crossbeam 3 is significantly improved, when installing the first swing arm
When mounting bracket 4 and the second swing arm mounting bracket 5, crossbeam 3 can be good at bearing suffered external force,
And the height of crossbeam 3 is with the crossbeam 3 away from the reinforcing mechanisms 7 of the first reinforcing mechanisms 6 or second
The ratio of height is 8:7, the installation site Z direction strength and rigidity of the second swing arm mounting bracket 5 are carried
Rise.

Ratio from X to length be 8:1.So, the both ends of crossbeam 3 are Y shape prong, and crossbeam 3 is in stress
When, no matter from that side stress, the power suffered by it, can be spread from middle part to end, due to end
Portion's Y shape prong, suffered power in transmittance process, can obtain it is good scattered, it is whole at crossbeam 3
Body dynamic stiffness minimum is brought up to 7400N/mm, is improved the entirety of crossbeam 3 by original 4000N/mm
Rigidity, increase the service life.
A kind of rear overhang swing arm crossbeam of the present invention, as shown in Figures 1 to 5, in previously described technical side
It can also be on the basis of case:First swing arm mounting bracket 4 is double-deck " u "-shaped.So, by
In first swing arm mounting bracket 4 be double-deck " u "-shaped, by outside the first swing arm mounting bracket 4
Side increases by one layer of reinforcing plate so that the integral thickness increase of the first swing arm mounting bracket 4, so as to increase by the
The Static stiffness of one swing arm mounting bracket 4, it is double-deck " u "-shaped by the first swing arm mounting bracket 44, the
The Static stiffness of one swing arm mounting bracket 4 is by original XIt is former=5000Nm/deg, YIt is former=4000Nm/deg, ZIt is former
=7000Nm/deg, brings up to XIt is former=11000Nm/deg, YIt is former=25000Nm/deg, ZIt is former=20000Nm/deg,
Structural strength is guaranteed, and increases the service life.
A kind of rear overhang swing arm crossbeam of the present invention, as shown in Figures 1 to 5, in previously described technical side
It can also be on the basis of case:The inner side of second swing arm mounting bracket 5 is provided with interior reinforcing plate 9, described
The outside of second swing arm mounting bracket 5 is provided with external reinforcing plate for car 10.So, in the second swing arm mounting bracket 5
Side is provided with interior reinforcing plate 9, and the outside of the second swing arm mounting bracket 5 is provided with external reinforcing plate for car 10, the second pendulum
Generally three layers of arm mounting bracket 5, structural strength is maximumlly lifted, the second swing arm mounting bracket
5 Static stiffness can be by original XIt is former=5000Nm/deg, YIt is former=3000Nm/deg, ZIt is former=5000Nm/deg,
Bring up to XIt is former=15000Nm/deg, YIt is former=19000Nm/deg, ZIt is former=20000Nm/deg, structural strength obtain
To guarantee, increase the service life.Preferred technical scheme is:Outside second swing arm mounting bracket 5
Wall, which is provided with, strengthens outside plate 8.So, installed additional on the outer wall of the second swing arm mounting bracket 5 and strengthen outside plate 8,
So that the sidepiece thickness of the second swing arm mounting bracket 5 gets a promotion, the second swing arm installation is further lifted
The bulk strength and rigidity of support 5, lift structure stability.
Described above is only the preferred embodiment of the present invention, it is noted that for the general of the art
For logical technical staff, without departing from the technical principles of the invention, some improvement can also be made
