Abstract
The utility model discloses a torsion beam type rear axle including a crossbeam and a left rear trailing arm assembly and a right rear trailing arm assembly which are connected at the left and the right ends of the crossbeam and combined by stamping parts, two plug welding holes for welding are arranged at the two ends of the crossbeam. The torsion beam type rear axle in the utility model greatly strengths the welding strength of the torsion beam type rear axle, improves the precision of the four-wheel locating parameter and the stable operation performance while ensuring the normal use of the torsion beam type rear axle.
Description
Technical field
The utility model relates to a kind of auto parts and components, specifically a kind of torsion girder type hind axle.
Background technology
Torsion girder type hind axle in the car of the torsion girder type hind axle of great majority employing at present is a kind of widely used axletree, the day for announcing is on December 3rd, 2008, notification number is the application for a patent for invention file of the applicant's application of CN101314313, just announced a kind of torsion girder type hind axle, behind this torsion girder-like as Fig. 1, shown in Figure 2, this torsion girder type hind axle comprises the left back trailing arm assembly 2 and the right back trailing arm assembly 3 of crossbeam 1 and crossbeam 1 both sides, be welded with at left back trailing arm assembly 2 and right back trailing arm assembly 3 and be used for and suspension bonded assembly left spring seat 5 and right back spring perch 6, a left side, right trailing arm assembly all selects for use round steel pipe to make, arrange along the axletree fore-and-aft direction, be connected with the vehicle body hinge by sleeve pipe 4 respectively, realize the installation of trailing arm assembly.But the weld strength of crossbeam two ends and forward and backward trailing arm assembly all is a length of controlling weld seam by the shape of beam-end, thereby guarantees the weld strength of torsion girder type hind axle.Because torsion girder type hind axle design itself is gone up and existed, causing crossbeam and forward and backward trailing arm assembly weld is the most serious stressed zone, and two weld seams guarantee that the weld strength of whole torsion girder type hind axle has certain risk about therefore only depending on.
The utility model content
The utility model proposes a kind of new torsion girder type hind axle in order to overcome the deficiency of torsion girder type hind axle in the prior art.
The utility model for realizing the technical scheme that its purpose adopts is: a kind of torsion girder type hind axle, comprise crossbeam and be connected the left back trailing arm assembly and the right back trailing arm assembly that constitute by blanked part at two ends, the crossbeam left and right sides, two plug welding holes of welding respectively are set at described crossbeam both ends.
Concrete, in above-mentioned a kind of torsion girder type hind axle: described plug welding hole is the waist shaped hole that is fan-shaped, by left circular arc, right circular arc, upward circular arc, circular arc encirclement down, described upward circular arc, following circular arc are respectively the isocentric circular arc that radius is 44mm, 35.3mm, on described circular arc, down between the circular arc, distance between the center of circle that described left circular arc, right circular arc are is 18mm, and radius all is the circular arc of 4.5mm.
Further, be respectively arranged with on described left back trailing arm assembly and the right back trailing arm assembly and be used for and the hinged connector bushing of vehicle body, described sleeve pipe line of centers becomes 15 ° of angles with horizon.
Torsion girder type hind axle of the present utility model when guaranteeing the normal use of rear axle, strengthens the weld strength of torsion girder type hind axle greatly, improves the precision of four wheel locating parameter, improves the handling stability energy.
Below with reference to drawings and Examples, the utility model is carried out comparatively detailed explanation.
Description of drawings
Fig. 1 is the birds-eye view of traditional torsion girder type hind axle.
Fig. 2 is the back view of traditional torsion girder type hind axle.
Fig. 3 is the front view and the birds-eye view of the torsion girder type hind axle of the utility model embodiment 1.

Among the figure: 1, crossbeam, 2, left back trailing arm assembly, 3, right back trailing arm assembly, 4, sleeve pipe, 5, left back spring abutment, 6, right back spring abutment, 7, the plug welding hole, 71, left circular arc, 73, right circular arc, 72, go up circular arc, 74, circular arc down, 8, rear brake duct road support.
The specific embodiment
Traditional torsion girder type hind axle as shown in Figure 1 and Figure 2, the weld strength of crossbeam and trailing arm all is a length of controlling weld seam by the shape of beam-end, thereby guarantees the weld strength of torsion girder type hind axle.Because torsion girder type hind axle design itself is gone up and existed, causing crossbeam and trailing arm weld is the most serious stressed zone, and two weld seams guarantee that the weld strength of whole torsion girder type hind axle has certain risk about therefore only depending on.
And in the present embodiment, as shown in Figure 3, Figure 4, central torsion girder type hind axle, two ends of crossbeam 1, each increases by two plug welding holes 7, has increased by four plug welding holes 7 altogether, carries out plug welding.Therefore crossbeam 1 both ends connect the greatly weakening of area of high stress of left back trailing arm assembly 2 and left back trailing arm assembly 3, can effectively reduce crossbeam 1 and overlap the situation of the stress concentration of local commissure, thereby prolong the fatigue proof service life of torsion girder type hind axle assembly of present embodiment with left back trailing arm assembly 2 and left back trailing arm assembly 3.
As shown in Figure 3, left back trailing arm assembly 2 and left back trailing arm assembly 3 are divided into the left-right symmetric trailing arm, with trailing arm bonded assembly sleeve pipe 4, its line of centers becomes 15 ° of angles with horizon, transition has turned to significant inhibitory effect to the Ackermann steer angle torsion girder type hind axle like this, thereby improve the vehicle handling and stability energy, described angle is generally between 15 °-20 °.
The torsion girder type hind axle of present embodiment, simple in structure, when guaranteeing torsion girder type hind axle four wheel locating parameter precision, strengthened the torsion girder type hind axle weld strength greatly, improve the precision of four wheel locating parameter, improved the handling stability energy, thereby strengthened the car load safety factor, reduce the risk that the user uses, reduced client's complaint.
