Abstract
The utility model discloses a commercial vehicle vibration reducing steel plate spring which comprises pieces of plate springs which are overlapped and connected into a whole. The two ends of the topmost layer of plate spring are respectively provided with a lifting lug which is used for connecting with a car frame. The two ends of the bottommost layer of plate spring are rolled to rolling lugs which are used for connecting with an absorber. The rolling lugs are respectively arranged at the two ends of the bottommost layer of plate spring of a traditional steel plate spring so that the bottom portion of a double absorber can be fixed reliably at the positions of the rolling lugs. Damping effects of a high hardness absorber are achieved by the double absorber with the help of the commercial vehicle vibration reducing steel plate spring. Smoothness and comfort of running of a heavy type cargo carrying vehicle is improved. Meanwhile, convenient installation of the double absorber is achieved. Spatial distribution of a part of a suspension system is reasonable. Moreover, when the double-rolling-lug type steel plate spring is adopted, the process of installation of the absorber is convenient and flexible. A single absorber and the double absorber can both be assembled. The commercial vehicle vibration reducing steel plate spring has the advantages of being simple in structure and low in production cost.
Description
Technical field
The utility model relates to the body mounting system, refers to particularly a kind of commercial vehicle/comm..vehicle vibration damping steel plate spring.
Background technology
The traveling comfort of vehicle is relevant with the natural vibration characteristic of vehicle body, and the natural vibration characteristic of vehicle body is relevant with the characteristic of suspension system, so suspension system is the vitals that guarantees vehicle riding comfort.Simultaneously, suspension system is again the vitals that guarantees ride safety of automobile as the power transmission parts that are connected between vehicle frame and the axletree.
Vehicle suspension system comprises elastic element, shock absorber and guiding mechanism three parts, and this three part plays respectively buffering, the transfer function of vibration damping and power.Wherein, steel spring is most widely used a kind of elastic element in the automotive suspension, and it is the elastic beam of an approximately equi-strength being combined by some wide but not isometric alloy spring sheets.The heavy-duty truck cargo tonnage is large, and steel spring rigidity is high, and the hardness of shock absorber also needs to improve thereupon, so double-shock absorber arises at the historic moment, and how properly to install fixedly double-shock absorber has just become problem demanding prompt solution.
The utility model content
The purpose of this utility model is to provide a kind of commercial vehicle/comm..vehicle vibration damping steel plate spring for the problems referred to above, and this vibration damping steel plate spring can provide the fixed position for double-shock absorber, so that double-shock absorber can satisfy the space layout requirement of suspension system parts the time easy for installation.
For achieving the above object, the technical solution adopted in the utility model is: a kind of commercial vehicle/comm..vehicle vibration damping steel plate spring, it comprises the stacked leaf spring that connects into integral body of multi-disc, the hanger that is connected for vehicle frame is established respectively at the two ends of the superiors' leaf spring, it is characterized in that: the two ends of orlop leaf spring roll into the grasswort that connects for shock absorber.
The utility model arranges respectively grasswort at the two ends of the orlop leaf spring of conventional steel plates spring, so that the bottom of double-shock absorber can be fixed on the grasswort place steadily, the utility model assists double-shock absorber to realize the effectiveness in vibration suppression of high hardness shock absorber, when also having avoided using single shock absorber, the too soft vehicle body that causes of shock absorber jumps up and down, or shock absorber causes the problem of the too large obstruction steel spring of resistance normal operation too firmly, improved the ride comfort that heavy duty truck travels, traveling comfort; Simultaneously, traditional steel spring can only be installed single shock absorber, often causes the shock absorber volume relatively large, the space layout that is unfavorable for parts, and the utility model is so that double-shock absorber is easy for installation, and the space layout of suspension system parts is reasonable, does not affect the layout of steering hardware; When adopting the steel spring of two grasswort forms in addition, the installation process of shock absorber is convenient, flexible, can assemble single shock absorber and can assemble double-shock absorber again; The utility model is simple in structure, and productive costs is low.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is working state figure of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, is convenient to more clearly understand the utility model, but they do not consist of restriction to the utility model.
As shown in Figure 1, the utility model comprises the stacked leaf spring 1 that connects into integral body of multi-disc, and the two ends of the superiors' leaf spring 1 are respectively equipped with hanger 4, and the two ends of orlop leaf spring 1 roll into respectively grasswort 6.The hanger 4 of the utility model by its superiors' leaf spring 1 two ends is connected with shackle bracket and is connected with vehicle frame 3, the middle part of leaf spring 1 is fixed on the vehicle bridge by U-bolt, the grasswort 6 at orlop leaf spring 1 two ends links to each other with the bottom of two single shock absorbers of double-shock absorber 2 respectively, that is two single shock absorbers that, form double-shock absorber 2 are separately fixed on the grasswort 6 at orlop leaf spring 1 two ends (such as Fig. 2).
Working process of the present utility model is as follows: when the road surface of heavy-duty truck process injustice, the vibration damping steel plate spring comes the absorbing vibration energy by deformation occurs self, filter out the vibrations on road surface, but reciprocating bounce-back trend is arranged after the shock-absorbing of vibration damping steel plate spring, the vibration damping steel plate spring stiffness of heavy-duty truck is large, concussion when being fixed on double-shock absorber 2 on the vibration damping steel plate both ends of the spring hanger 6 and being used for suppressing the vibration damping steel plate springback and from the impact on road surface, thereby avoided the severe bounce of vibration damping steel plate spring, thereby reached the vibration damping purpose, further improved ride comfort and traveling comfort that heavy-duty truck travels.
Claims (1)
1. commercial vehicle/comm..vehicle vibration damping steel plate spring, it comprises that multi-disc is stacked and connects into whole leaf spring, the hanger that is connected for vehicle frame is established respectively at the two ends of the superiors' leaf spring, it is characterized in that: the two ends of orlop leaf spring roll into the grasswort for the shock absorber connection.
