Abstract

The utility model discloses a minitype automotive steel plate spring front lug assembly. The minitype automotive steel plate spring front lug assembly comprises a front lug left side part, a front lug right side part and a side connecting part, wherein the front lug left side part and the front lug right side part are symmetrical, a bending portion on the lower portion of the front lug left side part and a bending portion on the lower portion of the front lug right side part are fixedly connected to form a front lug, corresponding assembly holes are arranged on two sides of the lower portion of the front lug respectively, the side connecting part is connected with the right edge of the front lug right side part, a front reinforcing part is arranged on the front side of the middle portion of the front lug, a rear reinforcing part is arranged on the back side of the upper portion of the front lug, and a lower reinforcing part is arranged at the lower edge of the connecting portion of the side connecting part and the front lug right side part. According to the minitype automotive steel plate spring front lug assembly, the structural strength of the front lug assembly is improved, the bearing capability is high, the local stress concentration is reduced, the service life is prolonged, and safety accidents caused by pull cracks can be avoided.

Description

Hanger assembly before a kind of mid-get car steel spring
Technical field
The utility model relates to automobile component, is specifically related to the front hanger assembly of a kind of mid-get car steel spring.
Background technology
Hanger assembly before the steel spring of mid-get car is the assembly part that is welded on the longeron back segment, and the position of weld is the rear end of longeron back segment, is used for the assembling steel spring.Hanger assembly before existing mid-get car steel spring, simple in structure, only be welded by front hanger body, cause the hanger insufficient strength, the stress value that can bear is little, and the stress value of sharing is large; Even the cracking situation appearred in the front hanger of some vehicle, and also before some vehicle, hanger also once came off, and had serious potential safety hazard.Abnormal reason appears in front hanger, roughly is divided into two kinds, a kind of insufficient strength for the front hanger outside (being the vehicle body left and right directions), and the stress value that can bear is little, but the fixing steel spring of load-bearing again; Another is the insufficient strength of front hanger bottom, and the gravity of whole steel leaf spring is downward, with the downward drawing crack of front hanger, causes major accident.Therefore, be badly in need of being improved.
Summary of the invention
The purpose of this utility model is to provide hanger assembly before a kind of mid-get car steel spring, and himself structural strength is high, and load-carrying capacity is strong, can reduce stress raisers, increases the service life, and avoids drawing crack and causes safety misadventure.
Hanger assembly before a kind of mid-get car steel spring described in the utility model, comprise front hanger left side part, with the front hanger right side part of front hanger left side part symmetry; Described front hanger left side part is captiveed joint with the bending part of part bottom, described front hanger right side and is consisted of front hanger, offer respectively the assembly opening of mutual correspondence in the both sides of described front hanger bottom, also comprise the side attaching parts that is connected with the right of described front hanger right side part; It is characterized in that:
Reinforcement before the front at described front hanger middle part is provided with, reinforcement after the back on described front hanger top is provided with is provided with reinforcement below at described side attaching parts and front hanger right side part connecting portion.
Further, be provided with an interior reinforcement on the inwall of described front hanger bottom.
Further, the section of described rear reinforcement is " U " shape.
Further, described side attaching parts is provided with multiple tracks Jia Qiang Zhu.
Compared to the prior art the utility model has the following advantages: owing to being located at respectively reinforcement on the inwall of front portion, rear portion, left part and the bottom of front hanger, thereby self structure intensity is high, and load-carrying capacity is strong; Because the right at front hanger is provided with the side attaching parts, this side attaching parts has been shared the part stress of front hanger, so reduced stress raisers, has extended service life, has avoided drawing crack and has caused safety misadventure.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the exploded view of Fig. 1;
Fig. 3 is the structural representation of front hanger left side part and front hanger right side part;
Fig. 4 is the constitution diagram that the utility model uses.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Referring to Fig. 1 hanger assembly to a kind of mid-get car steel spring shown in Figure 3, comprise front hanger left side part 1, with the front hanger right side part 4 of front hanger left side part symmetry; Described front hanger left side part 1 is captiveed joint with the bending part of part 4 bottoms, described front hanger right side and is consisted of front hanger, offer respectively the assembly opening of mutual correspondence in the both sides of described front hanger bottom, also comprise the side attaching parts 3 that is connected with the right of described front hanger right side part 4; Reinforcement 5 before the front at described front hanger middle part is provided with, reinforcement 2 after the back on described front hanger top is provided with is provided with reinforcement 6 below at described side attaching parts 3 and front hanger right side part 4 connecting portions.
Be provided with an interior reinforcement 7 on the inwall of described front hanger bottom.
The section of described rear reinforcement 2 is " U " shape.
Described side attaching parts 3 is provided with multiple tracks Jia Qiang Zhu.
Front hanger assembly is concrete to be installed and uses referring to Fig. 4: the top of front hanger be stuck in the upper of longeron back segment, and fix by welding and longeron, one end of steel spring 9 and the front end of longeron are fixed, the other end of steel spring 9 is connected by the assembly opening of bearing pin with both sides, front hanger bottom, and side attaching parts 3 welds with other crossbeam.
Intensity of the present utility model is reliable, stability is high; And the welding of front hanger self is comprised of CO2 protection weldering and spot-welded on, and the place all adopts intensity failure-free CO2 protection weldering at its key structure, and welding gun spot welding has efficiently been adopted in remaining place; When current hanger is welded on the longeron back segment, first adopt first spot welding, then protect the form of weldering, guarantee intensity, the rigidity of front hanger.
In the process of mid-get car in fast running, because steel spring has been born larger pressure, it is delivered to the pressure that bears above front hanger, particularly in front hanger both sides, at this moment the side attaching parts that is welded on longitudinal beam connecting piece has been shared a part of pressure, guarantees the better shock-absorbing function of steel spring.
