Abstract
The utility model provides a car-body rear spring supporting seat with strengthening structure, which relates to a transmission-power frame, a rear-floor side plate is welded with a rear-floor strengthening beam and then is welded with a lower angle plate of a parcel shelf to form the transmission-power frame. One plane of the rear-floor strengthening beam is a rear spring supporting seat surface,the rear spring is installed at the lower surface of the rear spring supporting seat surface; the characteristics of the utility model are as follows; the middle vacant part of the upper surface of the rear spring supporting seat surface is parallel provide with strengthening plates at vertical direction in a welding way, the strengthening plates and the flat plane, the vertical plane of the rear-floor side plate and the upper surface of the spring supporting seat surface form three-surface welding, and a frame structure is formed. Through welding the newly designed rear spring supporting seat strengthening plates at the vacant part of the rear spring supporting seat surface, the frame structure with good structural strength is formed, in order to enhance the stiffness, strength of the rear spring supporting seat, and the fatigue strength of the rear spring supporting seat is increased, the purpose of increasing the fatigue durability of the car-body is achieved.
Description
Technical field
The utility model belongs to the auto body field, is specifically related to a kind of vehicle body rear spring bearing with additional strengthening.
Background technology
The rear spring bearing bears spring and arrives vehicle body from ground-surface load and transmission power, is the vitals of auto body endurance quality.Existing rear spring seat structure as shown in Figure 1, after rear floor margin plate 2 and the back-floor reinforcement beam 3 welding combinations, again with the glove plate under gusset 1 weld, form the main power transmission framework of rear spring bearing.Rear wheel load passes to rear spring seating plane 31 through rear spring, is delivered to rear floor margin plate 2 by back-floor reinforcement beam 3 again, and gusset 1 passes to vehicle body under the glove plate.Because existing spring bearing structure is equivalent to the cantilever beam force way at spring bearing face 31 positions, in the power of transmission process, big stress concentration occurs at rear floor margin plate regional area A (as Fig. 1), reduced the intensity of rear spring bearing, the vehicle body fatigue durability can be weakened.
By many motorcar body CAE Numerical Simulation Analysis are confirmed that also existing rear spring bearing exists stress raisers serious more, deflection is big, and fatigue life is lower, can not satisfy the design objective value.
Summary of the invention
At the deficiencies in the prior art, the utility model provides a kind of rear spring bearing with additional strengthening, and it is optimized the rear spring seat structure, strengthens the intensity of spring bearing, improves vehicle body fatigue durability energy.
The technical solution of the utility model is as follows:
A kind of vehicle rear spring bearing with additional strengthening, described bearing is by after rear floor margin plate and the back-floor reinforcement beam welding combination, again with the glove plate under gusset welding and the power transmission framework that forms, plane on the described back-floor reinforcement beam is the rear spring seating plane, and rear spring is installed in the lower surface of rear spring seating plane; It is characterized in that: at the vertical parallel brace panel that is welded with of the middle room part of the upper surface of described rear spring seating plane, the upper surface of the plane of brace panel and rear floor margin plate, facade and spring bearing face forms three welding, the formation framed structure.
The utility model is by welding newly-designed rear spring bearing brace panel in the null position at rear spring seating plane position, form structural strength good framework structure, the rear spring bearing is firm to strengthen, intensity, improves rear spring bearing strength at repeated alternation, reaches to improve vehicle body fatigue durability energy purpose.
By carrying out Fatigue Strength Analysis and last verification experimental verification, find that rear spring bearing strength at repeated alternation significantly improves, and satisfies operating needs, thereby has improved vehicle body fatigue durability energy to improving the back body in white.And by the checking of many moneys vehicle, this rear spring seat structure form and mounting means are applicable to multiple car.
Description of drawings
Fig. 1 is existing rear spring seat structure scheme drawing;
Fig. 2 is the utility model structural representation;
Fig. 3 is the utility model rear spring bearing brace panel structural representation.
Wherein, gusset under the 1-glove plate; The 2-rear floor margin plate; The 3-back-floor reinforcement beam; The 4-brace panel; 31-spring bearing face; The 41-waling; A-rear floor margin plate areal of stress concentration.
The specific embodiment
As shown in Figure 2, vehicle rear spring bearing comprises gusset 1 under the glove plate, rear floor margin plate 2, back-floor reinforcement beam 3 and brace panel 4.After rear floor margin plate 2 and the back-floor reinforcement beam 3 welding combinations, again with the glove plate under gusset 1 welding and form the power transmission framework of rear spring bearing.Plane on the back-floor reinforcement beam 3 is a rear spring seating plane 31, rear spring is installed in the lower surface of rear spring seating plane 31, the vertical parallel welding brace panel 4 of the middle room part of the upper surface of rear spring seating plane 31, brace panel 4 forms three welding with the upper surface of plane, facade and the spring bearing face 31 of rear floor margin plate 2, forms framed structure.
As shown in Figure 3, the version of two brace panels 4 is identical, and height dimension omits by difference according to the concrete position of installing.Its resemblance is a right-angled trapezium plate muscle spare, on brace panel with the trapezoidal hypotenuse waling 41 that be arranged in parallel, run through trapezoidal following, to increase the intensity of plate.Near near the design trapezoidal hypotenuse two auxiliary holes are arranged at reinforced rib, leak when being used for car body coating.For strengthening structural strength, make things convenient for the welding of brace panel and rear spring bearing simultaneously, brace panel has designed three flange except that trapezoidal hypotenuse, and the brace panel of this version has good structural strength.
This brace panel concrete connection mode in vehicle body is: at the re-entrant portion of existing rear spring bearing, two brace panels 4 are arranged in parallel in the centre of spring bearing face 31, three flange of brace panel 4 respectively with floor level, back, facade, spring bearing face welding (as Fig. 2).Form all framed structures preferably of shock resistance, antitorque commentaries on classics performance, with improve the rear spring bearing just, intensity, reduce rear spring bearing stress deformation, reduce the stress concentration of rear spring seating plane and rear floor margin plate, improve rear spring seat structure strength at repeated alternation.
