Abstract
The utility model relates to a multifunctional front plate spring rear bracket. The front plate spring rear bracket and a lower crossbeam bracket are combined into a whole by adopting the casting technique, and a lower cross beam is directly connected with the front plate spring rear bracket. The front plate spring rear bracket comprises four or five holes with the upper part formed in a trapezoid manner and used for connecting the longitudinal beam of a vehicle frame; reinforcing ribs are arranged among the holes; two to three vertical holes formed at the middle part are connected with the lower wing surface of the longitudinal beam; a large hole at the front end of the lower part is a connecting hole of the lifting lug of the plate spring; four or five holes formed in a trapezoid manner are formed at the rear end of the lower part and are used for connecting the lower crossbeam, and an included angle alpha (2 degrees to 6 degrees) is formed between the connecting face of the lower cross beam and the longitudinal and vertical plane of the vehicle frame; and two to three reinforcing ribs are arranged on the outer side simultaneously. The utility model has the advantages of compact structure, simple process, easy manufacture, low cost, security and reliability, and convenience and practicality, and is suitable for popularization and application.
Description
Technical field
The utility model relates to a kind of preceding flat spring bracket, specifically a kind of multi-functional preceding leaf spring after poppet.
Background technology
Heavy duty truck is had relatively high expectations to the structural strength of vehicle frame because bearing capacity is big.Because anterior layout driving engine and the change-speed box of needing of vehicle frame, first crossbeam of vehicle frame often can not arrange too by the vehicle frame front portion, a little less than causing the anterior intensity of vehicle frame, a lot of producers that heavily block all take to strengthen vehicle frame in the measure of change-speed box bottom increase cross sill, what cross sill had directly connects to ground, and the support that passes through that has connects to ground.The layout of cross sill and support thereof will be subjected to the driving engine location influence, also will consider the problems such as position influence with the gap of change-speed box, ground Clearance, preceding leaf spring after poppet.Because the space is very nervous, several aspects mutual restriction, the layout of cross sill and support thereof are often relatively more difficult.
The utility model content
Technical problem to be solved in the utility model provides a kind of multi-functional preceding leaf spring after poppet at the existing in prior technology defective, adopt foundry technique that preceding leaf spring after poppet and cross sill support are combined together, cross sill directly is connected with preceding leaf spring after poppet, not only strengthened vehicle frame but also strengthened preceding leaf spring after poppet, compact conformation, technology is simple.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of multi-functional preceding leaf spring after poppet, described preceding spring after poppet and cross sill support combine together, and are about to cross sill and directly are connected with preceding leaf spring after poppet.
Described preceding spring after poppet top is connected with chassis side rail with 4 or 5 holes and these holes are trapezoidal layout, is provided with reinforced rib between the hole.
Being provided with 2～3 vertical holes in the middle part of the spring after poppet before described is connected with the longeron lower aerofoil.
Spring after poppet bottom front end is provided with and leaf spring hanger bonded assembly macropore before described.
Rear end, spring after poppet bottom has the hole of 4 or 5 trapezoidal layouts to be used for connecting cross sill before described, and and the joint face of cross sill and vehicle frame longitudinal vertical plane between angle α is arranged, wherein α is 2 °～6 °, is provided with 2～3 road reinforced ribs simultaneously in the outside.
A kind of multi-functional preceding leaf spring after poppet of the present utility model compared with prior art has following beneficial effect:
1. preceding leaf spring after poppet and cross sill support are combined together, compact conformation, intensity is higher, and technology is simple, has reduced the part kind, has reduced automotive dead weight.
2. this multi-functional preceding leaf spring after poppet and 5 (or 4) holes of chassis side rail bonded assembly are trapezoidal layout, and are provided with reinforced rib each other, and rational in infrastructure, joint face is big, bulk strength height, firm and reliable connection.
3. this multi-functional preceding leaf spring after poppet middle part has 2～3 vertical holes to be connected with the longeron lower aerofoil, has further increased this support and chassis side rail bonded assembly reliability, has strengthened the antitorque resistance to tension of entire bracket.
4. this multi-functional preceding leaf spring after poppet bottom front end has and leaf spring hanger bonded assembly macropore (8), makes this support play the effect of preceding leaf spring after poppet.
5. this multi-functional preceding rear end, leaf spring after poppet bottom connects cross sill by the hole of 4 (or 5) trapezoidal layouts, and and angle α ° (2 °～6 °) are arranged between the joint face of cross sill and the vehicle frame longitudinal vertical plane, and be provided with 2～3 road reinforced ribs in the outside.This structure design makes cross sill that the failure-free attachment point arranged, and is not easy to be torn, to twist off.
6. safe and reliable, convenient and practical, easy to manufacture, with low cost, suitable applying.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is further specified.
Fig. 1 is a kind of structural front view of multi-functional preceding leaf spring after poppet;
Fig. 2 is a kind of structure left view of multi-functional preceding leaf spring after poppet.
Wherein: 1, hole; 2, reinforced rib; 3, longeron joint face; 4, lower aerofoil connecting bore; 5, cross sill joint face; 6, hole; 7, reinforced rib; 8, macropore.
The specific embodiment
According to Fig. 1, shown in Figure 2, a kind of multi-functional preceding leaf spring after poppet, described preceding spring after poppet and cross sill support combine together, and are about to cross sill and directly are connected with preceding leaf spring after poppet.
Described preceding spring after poppet top is connected with chassis side rail with 5 holes 1 and these holes are trapezoidal layout, is provided with reinforced rib 2 between hole 1.Rational in infrastructure, the intensity height makes the firm and reliable connection of longeron joint face 3 and vehicle frame.
Being provided with 2～3 vertical lower aerofoil connecting bores 4 in the middle part of the spring after poppet before described is connected with the longeron lower aerofoil.
Spring after poppet bottom front end is provided with and leaf spring hanger bonded assembly macropore 8 before described.
Rear end, spring after poppet bottom has the hole 6 of 4 or 5 trapezoidal layouts to be used for connecting cross sill before described, and and cross sill joint face 5 and vehicle frame longitudinal vertical plane between angle α is arranged, wherein α is 2 °～6 °, is provided with simultaneously 2～3 road reinforced ribs 7 in the outside.
During manufacturing, the leaf spring after poppet can adopt cast iron or cast steel material to cast, process according to the car load load bearing requirements before this was multi-functional.
During use, can leaf spring after poppet before multi-functional be fixed on the chassis side rail by bolt or other fasteners, utilize bolt or other fasteners that cross sill is fixed on the multi-functional preceding leaf spring after poppet then, by spring pin leaf spring hanger and multi-functional preceding leaf spring after poppet are coupled together and can use at last.
