Abstract
The invention provides a rear axle reinforcement plate structure which comprises a reinforcement plate and an axle housing. The reinforcement plate and the axle housing are welded, the distance between a welding seam and the center line of the axle housing is less than 10mm, and the welding seam is between the reinforcement plate and the axle housing. The rear axle reinforcement plate structure has the advantages of optimizing the welding position of the reinforcement plate and the axle housing, and avoiding the stress concentration problem of the reinforcement plate and the axle housing.
Description
Technical field
The present invention relates to back axle brace panel structure, relate in particular to a kind of concentrated back axle brace panel structure of stress of avoiding.
Background technology
The stress of existing back axle brace panel structure is concentrated comparatively obvious, causes easily occurring the defect of cracking.
Summary of the invention
In order to solve the problems of the prior art, the invention provides a kind of concentrated back axle brace panel structure of stress of avoiding.
The invention provides a kind of back axle brace panel structure, comprise brace panel and axle housing, described brace panel welds mutually with described axle housing, and the spacing of the weld seam between described brace panel and described axle housing and the line of centers of described axle housing is less than 10 millimeters.
As a further improvement on the present invention, the spacing of the line of centers of the weld seam between described brace panel and described axle housing and described axle housing is less than or equal to 8 millimeters.
As a further improvement on the present invention, the end of the weld seam between described brace panel and described axle housing is arc.
As a further improvement on the present invention, the end of the weld seam between described brace panel and described axle housing is circular arc.
As a further improvement on the present invention, the end of the weld seam between described brace panel and described axle housing is that radius is the circular arc of 10 millimeters.
As a further improvement on the present invention, described brace panel is overlapped on described axle housing.
As a further improvement on the present invention, the weld seam between described brace panel and described axle housing comprises main part, interconnecting gangway and terminal part, and described main part parallels with the line of centers of described axle housing, and described interconnecting gangway is arc, and described terminal part is arc.
As a further improvement on the present invention, the radius of described interconnecting gangway is greater than the radius of described terminal part.
As a further improvement on the present invention, the line of centers of described terminal part and described axle housing intersects.
The invention has the beneficial effects as follows: by such scheme, optimized the position of weld of brace panel and axle housing, avoided the concentrated problem of brace panel and axle housing stress.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of back axle brace panel of the present invention structure;
Fig. 2 is the partial enlarged drawing A of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing explanation and the specific embodiment, the present invention is further described.
Drawing reference numeral in Fig. 1 to Fig. 2 is: brace panel 1; Axle housing 2; Line of centers 21; Weld seam 3; Main part 31; Interconnecting gangway 32; Terminal part 33.
As shown in Figure 1 to Figure 2, a kind of back axle brace panel structure, comprise brace panel 1 and axle housing 2, described brace panel 1 welds mutually with described axle housing 2, the spacing L1 of the weld seam between described brace panel 1 and described axle housing 2 and the line of centers 21 of described axle housing 2 is less than 10 millimeters, after optimizing, brace panel 1 end weld seam 3 more approaches the neutral surface of axle housing 2 distortion, and the deformation at weld seam 3 places reduces, and stress decrease is obvious simultaneously.
As shown in Figure 1 to Figure 2, weld seam 3 between described brace panel 1 and described axle housing 2 is less than or equal to 8 millimeters with the spacing L1 of the line of centers 21 of described axle housing 2, and the weld seam 3 between described brace panel 1 and described axle housing 2 is preferably 8 millimeters with the spacing L1 of the line of centers 21 of described axle housing 2.
As shown in Figure 1 to Figure 2, the end of the weld seam 3 between described brace panel 1 and described axle housing 2 is arc.
As shown in Figure 1 to Figure 2, the end of the weld seam 3 between described brace panel 1 and described axle housing 2 is circular arc.
As shown in Figure 1 to Figure 2, the end of the weld seam 3 between described brace panel 1 and described axle housing 2 is that radius is the circular arc of 10 millimeters.
As shown in Figure 1 to Figure 2, described brace panel 1 is overlapped on described axle housing 2.
As shown in Figure 1 to Figure 2, weld seam 3 between described brace panel 1 and described axle housing 2 comprises main part 31, interconnecting gangway 32 and terminal part 33, described main part 31 parallels with the line of centers 21 of described axle housing 2, described interconnecting gangway 32 is arc, described terminal part 33 is arc, the length L 2 of described terminal part 33 and highly L3 are 10 millimeters, avoid brace panel 1 and axle housing 2 overlap joint ends to occur large welding round dot because welding stops, and cause that stress is concentrated.
As shown in Figure 1 to Figure 2, the radius of described interconnecting gangway 32 is greater than the radius of described terminal part 33.
As shown in Figure 1 to Figure 2, described terminal part 33 intersects with the line of centers 21 of described axle housing 2.
The advantage of a kind of back axle brace panel structure provided by the invention is:
1. optimize weld seam 3 trend and the arrangements of axle housing 2 and brace panel 1, avoided weld seam 3 to appear at the large position of axle housing 2 deflections;
2. by the tip designs of the weld seam 3 between described brace panel 1 and described axle housing 2, be arc, avoid weld seam 3 ends to occur that stress is concentrated.
Above content is in conjunction with concrete preferred implementation further description made for the present invention, can not assert that specific embodiment of the invention is confined to these explanations.For general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
