Abstract
The utility model discloses a kind of Rear secondary frame for vehicle stirrup structure, comprise subframe, subframe is made up of front cross rail, after cross member and vertical welding left longeron between, right vertical beam, two spaced apart, two openings stirrup supports are outwardly installed by welding with in the middle part of front cross rail, after cross member both sides are installed by welding with two spaced apart, opening rear stirrup supports inwardly, are provided with the left stirrup be obliquely installed, right stirrup between the front stirrup support of homonymy and rear stirrup support; In the middle part of left longeron, right vertical beam outer wall, suspension link support is all installed.The utility model reasonable in design, is all greatly improved for the longitudinal direction of subframe and lateral rigidity, avoids because causing subframe to be out of shape the excessive strength problem brought under the operating modes such as turning, braking, and contributes to improving automobile ride; Integral structure is simple, and comparatively obvious to the integral rigidity improving subframe, cost is lower, production is easy to realize, and is convenient to Assembly &Disassembly.
Description
Technical field
The utility model relates to automobile manufacturing field, particularly relates to a kind of Rear secondary frame for vehicle stirrup structure.
Background technology
Subframe can regard the skeleton of tandem axle as, is the component part of tandem axle.Subframe incomplete vehicle frame, just supported the support of tandem axle, suspension, make vehicle bridge, hang and be connected with " positive vehicle frame " by it again, be called traditionally " subframe ".
Subframe brings convenience and preceence in design and installation, meanwhile also band serve problem: first, need subframe have enough Rigidity and strengths to ensure automobile turn, braking time be unlikely to distortion excessive; Secondly, under jumping operating mode is hung down in single-wheel, subframe mainly bears flexion torsion load, and under larger moment of flexure or torsional interaction, subframe insufficient rigidity also can cause structure partial to destroy; Again, the subframe that rigidity is less can reduce the ride comfort of automobile in the process of moving.
Utility model content
The purpose of this utility model is to provide a kind of Rear secondary frame for vehicle stirrup structure, and actv. improves the integral rigidity of Rear secondary frame for vehicle, reduces automobile turning, under the operating modes such as jumping of hanging down due to the destruction risk that insufficient rigidity causes.
The technical solution of the utility model is as follows:
Rear secondary frame for vehicle stirrup structure, comprise subframe, subframe is made up of front cross rail, after cross member and vertical welding left longeron between, right vertical beam, it is characterized in that: in the middle part of described front cross rail, be installed by welding with two spaced apart, two openings front stirrup supports outwardly, after cross member both sides are installed by welding with two spaced apart, opening rear stirrup supports inwardly, be provided with the left stirrup be obliquely installed, right stirrup between the front stirrup support of homonymy and rear stirrup support, left stirrup, right stirrup form V-type; In the middle part of described left longeron, right vertical beam outer wall, suspension link support is all installed.
Described Rear secondary frame for vehicle stirrup structure, is characterized in that: described left stirrup, right stirrup become V-type, and the angle between left pipe link, right pipe link is between 30 ~ 60 °.
Described Rear secondary frame for vehicle stirrup structure, is characterized in that: described left stirrup adopts internal diameter 22mm, the hollow circular-tube of wall thickness 3mm.
Described Rear secondary frame for vehicle stirrup structure, is characterized in that: described right stirrup uses length to be 30mm, and wide is the channel beam of 13mm, wall thickness 3mm, because channel beam cross section is opening down.
The utility model has the advantages that:
1. in the utility model, stirrup structure is that " V " font is arranged, the longitudinal direction of subframe and lateral rigidity are all greatly improved, avoid because causing subframe to be out of shape the excessive strength problem brought under the operating modes such as turning, braking, and contribute to improving automobile ride;
2. the stirrup in the utility model is stronger in conjunction with round section rod member anti-twisting property, the mechanics principle that channel-section rod member resistance to bending is stronger, selects the rod member of round section and channel-section as reinforcement structure respectively;
3. the difference that the stirrup in the utility model can be arranged according to auxiliary frame structure, changes size and the wall thickness of stirrup, also can do respective change to the setting angle of stirrup;
4. stirrup structure provided by the utility model is simple, and comparatively obvious to the integral rigidity improving subframe, cost is lower, production is easy to realize, and is convenient to Assembly &Disassembly.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
See accompanying drawing:
Rear secondary frame for vehicle stirrup structure, comprise subframe 1, subframe is made up of front cross rail, after cross member and vertical welding left longeron between, right vertical beam, two spaced apart, two openings front stirrup supports 2 are outwardly installed by welding with in the middle part of front cross rail, after cross member both sides are installed by welding with two spaced apart, opening rear stirrup supports 3 inwardly, be provided with the left stirrup 4, the right stirrup 5 that are obliquely installed between the front stirrup support 2 of homonymy and rear stirrup support 3, left stirrup 4, right stirrup 5 form V-type; In the middle part of left longeron, right vertical beam outer wall, suspension link support 6 is all installed.
Left stirrup 4, right stirrup 5 one-tenth V-type, the angle between left stirrup 4, right stirrup 5 is between 30 ~ 60 °, and angle can adjust accordingly according to space deployment scenarios.
Left stirrup 4 adopts internal diameter 22mm, the hollow circular-tube of wall thickness 3mm, and the rod member anti-twisting property of round section is stronger; Right stirrup 5 uses length to be 30mm, and wide is the channel beam of 13mm, wall thickness 3mm, and because channel beam cross section is opening down, the rod member resistance to bending of channel-section is stronger, the end of channel beam with carry out bolt below the reinforced support of front and back and be connected.According to the rigidity situation of subframe reality, the size of stirrup and thickness can make corresponding change.
Claims (4)
