Description
Technical field
The utility model relates to automobile component field, particularly a kind of automobile torsion beam back axle.
Background technology
In the prior art, automobile torsion beam back axle refers to and is used to support wheel and the device being connected rear wheel by the rear drive shaft component part that vehicle power transmits.
Fig. 1 is the block diagram of existing automobile torsion beam back axle.As shown in Figure 1, certain family-sized car torsion beam rear axle connects two ends trailing arm 12 by crossbeam 11, realizes the connection between vehicle body by the lining pipe 13 of trailing arm 12 front end after press-fiting rubber bush.Adopt the axle journal connecting panel 14 of trailing arm 12 rear end to realize and the connection of wheel, with bracket assy., spring seat 15 coordinate coil spring, damper bracket 16 coordinates shock absorber to realize being connected with the soft of vehicle body, to reach the effect of vibration damping and support tare.Its integral structure is simply compact, and compare the independent suspension of multi link formula and numerous connecting rod, it takes up room less, more space can be used for arranging rear space and boot compartment, effectively can reduce the height of car bottom plate.In addition, its design difficulty, research and development cost, manufacturing cost etc. are compared independent suspension and are also had greater advantages, so torsion beam rear axle is widely used on the SUV of low and middle-end family-sized car and low side.

The utility model solves above-mentioned technical matters by following technical proposals: a kind of automobile torsion beam back axle, it comprises crossbeam and two trailing arms, described crossbeam is connected between described two trailing arms, its feature is, described crossbeam adopts the open-type crossbeam of sheet profile, the cross section of the main body of described crossbeam is V-shaped, and the lower end in described cross section is provided with flange, and the cross section at the two ends of described crossbeam is U-shaped.
Preferably, in the main body of described crossbeam, at the two ends place near described crossbeam, punching press has a pit respectively.
Preferably, be provided with brace panel in described crossbeam, described brace panel punching press is R angle, and the vertical cross-section of described brace panel is curved.
Preferably, the end of described trailing arm is connected with axle journal connecting panel.
Preferably, described axle journal connecting panel adopts Sheet Metal Forming Technology to arrange axle journal assembly opening.
Preferably, described trailing arm offers multiple tooling hole.
Positive progressive effect of the present utility model is:
The utility model automobile torsion beam back axle eliminates the machined holes of wheel bundle sensor machining hole and axle journal support being installed axle journal, adopts Sheet Metal Forming Technology to complete axle journal 4 assembly openings, has saved productive costs.Meanwhile, in order to expendable weight assembles with being convenient to, trailing arm has been opened 2 tooling holes, for the assembling of axle journal.Which reduce the stress of local, and improve the torsional stiffness of back axle.
