Abstract
The utility model provides an automobile leaf spring-typed suspension saddle typed cushion plate assembly, comprising a saddle-typed cushion plate and a pin shaft used for installing a damper; the saddle plane of the saddle cushion plate is provided with four bolt holes which are matched with riding bolts; the pin shaft is welded at one side part of the saddle-typed cushion plate in parallel. The improvement of the assembly is that a reinforced slab which is parallel to the saddle plane is welded between the two side parts of the saddle-typed cushion plate; the pin shaft is welded and fixed with the side part of the saddle-typed cushion plate and the reinforced slab in parallel at the same time; therefore, the profile of the stress concentration area is enclosed rectangle structure, the stress distribution is extremely ideal, the stress concentration is avoided, the fatigue service life of the saddle-typed cushion plate is greatly prolonged, and the comfort, the maneuverability and the driving safety of the automobile are improved.
Description
Technical field
The utility model relates to the car chassis structure, is specifically related to leaf springs of car formula suspension saddle backing structure.
Background technology
Usually, by saddle backing plate, saddle clamp leaf spring and axle assembly constraint are fixed together in the existing leaf springs of car formula suspension, and attachment point is also on the saddle backing plate under the rear shock absorber, so saddle backing plate assembly parts are for closing heavy mail, lost efficacy as this part and will cause car body and phenomenon such as the bridge running device breaks away from, shock absorber is ineffective, thereby cause very serious accident to take place.Referring to Fig. 1, existing saddle backing plate assembly is the sidepiece that the bearing pin 2 of mounting dampers is welded in parallel saddle backing plate 1, saddle backing plate 1 is a channel, bearing pin 2 and saddle backing plate 1 join domain A mainly bear the pressure of shock absorber, and the fixedly load of back axle and leaf spring of most of constraint is then born in the zone in four holes 3 that the saddle backing plate 1 and the mule bolt of riding match.There is the welding region A stress concentration of bearing pin 2 and saddle backing plate 1 in such structure, and fatigue life is low, the saddle backing plate often takes place tear in this zone, causes saddle backing plate assembly entirely ineffective, can not satisfy operating needs,
Summary of the invention
For overcoming the deficiency that prior art exists, the utility model proposes a kind of leaf springs of car formula suspension saddle backing plate assembly of rigidity and intensity, high fatigue life preferably that has.
The technical solution of the utility model is as follows:
Leaf springs of car formula suspension saddle backing plate assembly includes the bearing pin of saddle backing plate and mounting dampers, and the saddle plane of saddle backing plate is provided with four bolts hole that match with saddle clamp, and bearing pin is welded on a sidepiece of saddle backing plate in parallel.The improvement of this assembly is that welding is dull and stereotyped with the parallel plane reinforcement of saddle between the both sides of saddle backing plate, bearing pin is fixed with the dull and stereotyped parallel welding of reinforcement with saddle backing plate sidepiece simultaneously, the section that makes area of stress concentration like this is the osed top rectangular configuration, so just make distribution of stress highly desirable, improve the service life of saddle backing plate assembly and the performance of car load.
Further, for saving in material, alleviate pts wt, the 1/3-1/2 that the reinforcement platen area is designed to the saddle plane gets final product.
Compared with prior art, the utlity model has following advantage:
1), have simple and reasonablely, distribution of stress is reasonable, has avoided stress concentration, has improved saddle backing plate tired service life greatly.
2) strength and stiffness height, weight is little.
3) traveling comfort, road-holding property and the driving safety of automobile, have been improved.

The specific embodiment
Referring to Fig. 2, Fig. 3 and Fig. 4, this leaf springs of car formula suspension saddle backing plate assembly includes the bearing pin 2 of saddle backing plate 1, mounting dampers and strengthens dull and stereotyped 4, saddle backing plate 1 is by the stamping forming channel of steel plate, the saddle plane of saddle backing plate 1 is provided with four bolts hole 3 that match with saddle clamp, be welded with between the both sides of saddle backing plate 1 and the parallel plane reinforcement flat board 4 of saddle, bearing pin 2 is fixed with the dull and stereotyped 4 parallel welding of reinforcement with a sidepiece of saddle backing plate 1 simultaneously.1/2 of the saddle plane that to strengthen dull and stereotyped 4 areas be saddle backing plate 1.Said structure is after the areal of stress concentration of bearing pin 2 and 1 welding of saddle backing plate has increased the reinforcement flat board, formed retangular section structure at areal of stress concentration, under the situation that does not increase thickness of slab, a stress concentration and a low difficult problem in tired service life have been solved easily like this
Claims (2)
1, leaf springs of car formula suspension saddle backing plate assembly includes the bearing pin of saddle backing plate and mounting dampers, and the saddle plane of saddle backing plate is provided with four bolts hole that match with saddle clamp, and bearing pin is welded on a sidepiece of saddle backing plate in parallel; It is characterized in that: be welded with between the both sides of saddle backing plate and the parallel plane reinforcement flat board of saddle, bearing pin is fixed with the dull and stereotyped parallel welding of reinforcement with saddle backing plate sidepiece simultaneously.
