Abstract
The utility model belongs to automotive filed discloses a car light weight leaf spring, including mainboard spring, subplate spring, spacing groove, bolt and plastic spacer layer, mainboard spring and subplate spring all are the arc structure, the radian of mainboard spring is less than the radian of subplate spring, the mainboard spring passes through bolted connection with the subplate spring in the middle part position, the both ends of subplate spring are equipped with the spacing groove respectively, the spacing groove with be connected through the slider between the subplate spring, be provided with plastic spacer layer, fibre layers and resin layer between the reed of the reed of mainboard spring and adjacent subplate spring. The utility model discloses a vice leaf spring support has been cancelled because main flat spring tip and adjacent vice flat spring bottom surface contactless just can not produce the friction noise in the use yet simultaneously to the leaf spring, can reduce whole car weight volume and save the cost, improves economic benefits, whole car ride comfort improves, and the driver is difficult for tiredly, has improved the transportation security.
Description
Technical field
The utility model relates to mechanical shock absorption field and especially relates to a kind of automobile light weight leaf spring.
Background technology
At present, auto-industry damping mainly uses plate spring sheet, the primary member of leaf spring is plate spring sheet, leaf spring hoop and bolt, the length of plate spring sheet is stepped successively decreases, stack piecewise with reverse pyramid, it is an entirety that leaf spring is connected by bolt and leaf spring hoop, and the plate spring sheet length of the superiors is maximum, hanger is bent out, for being installed on below car body by leaf spring at its two ends.When leaf spring is stressed, utilize the elastic force of leaf spring self, reach the effect of compensator or trimmer pressure, but owing to fitting tightly between plate spring sheet, stressed bending time rub mutually and can produce abnormal sound.Secondly mainboard spring is consistent with subplate spring radian, is fixed by saddle clamp, this kind of leaf spring when vehicle is unloaded Vehicular vibration, jolt greatly, car load ride comfort is poor, and navigating mate is easily tired.The automotive suspension leaf spring of existing routine, mainboard spring is consistent with subplate spring radian, is fixed by saddle clamp, this kind of leaf spring when vehicle is unloaded Vehicular vibration, jolt large, car load ride comfort is poor, and navigating mate is easily tired.
Utility model content
For deficiency of the prior art, the utility model provides a kind of leaf springs of car of stiffness variable, and car load ride comfort when can significantly improve commercial vehicle/comm..vehicle underloading, can alleviate leaf spring abnormal sound simultaneously.
The technical solution adopted in the utility model is: a kind of leaf springs of car, comprise mainboard spring, subplate spring, position-limited trough, bolt and plastic mattress lamella, described mainboard spring and subplate spring are all arcuate structure, the radian of described mainboard spring is less than the radian of subplate spring, described mainboard spring and subplate spring are bolted at medium position, the two ends of described subplate spring are respectively equipped with position-limited trough, be connected by slide block between described position-limited trough with described subplate spring, plastic mattress lamella is provided with between the reed of described mainboard spring and the reed of adjacent subplate spring, carbon fiber layer and resin bed, described resin bed is arranged between described plastic mattress lamella and carbon fiber layer,
Described leaf spring also comprises leaf spring hoop, and the two ends of described mainboard spring are fixedly connected with subplate spring by described leaf spring hoop.
Preferably, the width of described position-limited trough is greater than the width of mainboard spring end, and the surface of described position-limited trough is provided with sucker, and the surrounding of described sucker is provided with rubber layer.
Preferably, the both sides of described mainboard spring are provided with hanger.
Preferably, resin bed is provided with between the reed of described subplate spring.
Advantage of the present utility model is with beneficial effect: because mainboard leaf end does not contact with adjacent subplate reed bottom surface, also friction noise would not be produced in use procedure, technique is simple, practical, eliminate auxiliary plate spring support simultaneously, complete vehicle weight can be reduced and save cost, increase economic efficiency; Car load ride comfort improves, and chaufeur is not easily tired, improves traffic safety.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of leaf springs of car of the utility model.
Detailed description of the invention
Be further described detailed description of the invention of the present utility model below in conjunction with drawings and Examples, following examples only for clearly the technical solution of the utility model being described, and can not limit protection domain of the present utility model with this.
As shown in Figure 1, a kind of leaf springs of car, comprise mainboard spring 1 and subplate spring 2, position-limited trough 3, bolt 4, plastic mattress lamella 5, the radian of this mainboard spring 1 is less than the radian of subplate spring 2, mainboard spring is connected by bolt 4 at medium position with subplate spring, and the two ends of subplate spring are respectively equipped with position-limited trough 3, and the reed of mainboard spring does not contact with the reed bottom surface of adjacent subplate spring, the radian of this mainboard spring 1 is less than the radian of subplate spring 2, subplate spring is following at mainboard spring, and respectively there are two position-limited troughs 3 subplate spring end, and major and minor leaf spring is connected by center bolt.Be connected by slide block between described position-limited trough with described subplate spring, realize can moving of position-limited trough, gap between adjustment mainboard spring 1 and subplate spring 2, is provided with plastic mattress lamella 5, carbon fiber layer and resin bed between the reed of described mainboard spring and the reed of adjacent subplate spring.Wherein resin bed is arranged between described plastic mattress lamella 5 and carbon fiber layer, thus the resonance decreased between mainboard spring and subplate spring and friction.
Mainboard spring can be conventional uniform cross section multi-disc leaf spring, also can be parabola shaped, and subplate reed number can be a slice also can be multi-disc, can need to make adjustment according to rigidity.This utility model leaf springs of car, because eliminating auxiliary plate spring support, can reduce complete vehicle weight and save cost, increase economic efficiency; Car load ride comfort improves, and chaufeur is not easily tired, improves traffic safety.In addition, in order to limit swinging of subplate spring, the width of position-limited trough 3 is greater than the width of mainboard spring end, and this position-limited trough 3 is affixed with described subplate spring.
Leaf spring of the present utility model also comprises leaf spring hoop 6, and leaf spring hoop 6, by plate spring sheet banding, prevents from loosening between subplate spring and mainboard spring.
Preferably, the width of described position-limited trough is greater than the width of mainboard spring end, and the surface of described position-limited trough is provided with sucker, and the surrounding of described sucker is provided with rubber layer.Be provided with sucker in position-limited trough of the present utility model, subplate spring can be held, prevent subplate spring from loosening to disturb mainboard spring.Further, around sucker, be provided with rubber layer, the friction between subplate spring and position-limited trough can be avoided.
Preferably, the both sides of described mainboard spring are provided with hanger.
Preferably, between the reed of described subplate spring, be provided with resin bed, avoid the shock between multi-disc subplate spring.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and replacement, these improve and replace and also should be considered as protection domain of the present utility model.
