Description
Technical field
A kind of lightweight equalizing type of suspension, belongs to survey balancing suspension technical field.
Background technology
Society's automobile industry development is rapid now, and new auto technology research and development and application are maked rapid progress, with vehicle enterprise pair
Lightweight, comfortableness, the pay attention to day by day of manipulation ride comfort, field of automobile suspension are faced with the megatechnics upgrading of a new round.
The lightweight products such as air suspension, rubber suspension, few leaf spring, have high-volume popularization and application trend in fields such as car, heavy trucks.From
The overall technology exploitation angle of vehicle sees that the performance such as safety, manipulation, comfortable, lightweight of suspension technology direct relation vehicle is
The important component of vehicle quality.Two leaf springs, rubber suspension etc. are employed on many cars, the new model of truck enterprise, with
The development and progress of Chinese society, people progressively carry to the requirement that automobile particularly heavy motor truck passes through property and comfortableness
It is high.The safety of structure that equalizing suspension system respectively constitutes parts directly affects the security of vehicle.
Traditional equalizing type of suspension mainly includes balance shaft support, crossbeam, distance rod and spring block, in the prior art suspension system
The leaf spring of system mainly plays cushioning effect, and distance rod plays a part of to transmit driving force and brake force.But just because of existing flat
The structure of weighing apparatus suspension is complex, and part is more various, and own wt is heavier, it is difficult to realize light-weighted target.Therefore, it is a kind of
Structure simplifies, is easy to modularized production, and the equalizing type of suspension that disclosure satisfy that lightweight needs is current problem demanding prompt solution.
The content of the invention
The technical problems to be solved by the invention are：Overcome the deficiencies in the prior art, there is provided a kind of structure simplifies, is easy to mould
Block metaplasia produce, disclosure satisfy that lightweight need without distance rod lightweight equalizing type of suspension.
The technical solution adopted for the present invention to solve the technical problems is：This is without distance rod lightweight equalizing type of suspension, and it is special
Levy and be：By driving jackshaft, back axle, beam mechanism, lifting force mechanism, leaf spring bindiny mechanism, balance shaft support, leaf spring is driven to connect
Joint chair is constituted, and leaf spring bindiny mechanism two ends connect described driving jackshaft and the bottom for driving back axle respectively by leaf spring connecting seat
Portion, leaf spring connecting seat top drives jackshaft and drives back axle by the clamping of vehicle bridge fixed card slot, and leaf spring connecting seat bottom is fixed and connected
Fishplate bar spring bindiny mechanism, by balance shaft support connecting cross beam mechanism, beam mechanism is overlapped on flat at the middle part of leaf spring bindiny mechanism
The top of weighing apparatus bracing strut.
Traditional suspension is highly to improve center of suspension to longitudinal beam center spring block reversion leaf spring to be placed in plate
Spring abutment lower section, inner underside is provided with independent propelling rod support.And the leaf spring bindiny mechanism upset of the application is installed, during installation, plate
The two ends of spring bindiny mechanism respectively by leaf spring connecting seat be fixedly connected drive jackshaft and drive back axle bottom, drive jackshaft and
Drive back axle that leaf spring is connected with middle back axle by former and later two leaf spring connecting seats respectively, such leaf spring can just rise simultaneously
To the connection function of distance rod, just without still further configuring the part such as lower thrust rod and leaf spring slide.
Lightweight equalizing type of suspension of the invention, is connected between vehicle frame outward, eliminates lower thrust rod, leaf spring slide and correlation
Connecting bolt, simplifies structure, reduces production cost, alleviates weight, and the operating efficiency that improve assembling is steady with assembling
It is qualitative, meanwhile, reduce follow-up maintenance and claim cost.Compared with existing equalizing type of suspension, whole suspension system is eliminated
Distance rod and leaf spring slide, directly replace lower thrust rod with leaf spring bindiny mechanism, by the effect of leaf spring bindiny mechanism and distance rod
Unite two into one, be capable of modularized production without distance rod lightweight equalizing type of suspension, middle part is horizontal by balance shaft support connecting cross beam
Lifting force mechanism is arranged with before and after beam so that conventional balance shaft support can be removed distance rod coupling part, weight is significantly
Decline, physical dimension diminishes so that stress reduction, service life is improved.
Preferably, crossbeam is arranged on frame inside, the inner side and frame outside phase of leaf spring bindiny mechanism and balance shaft support
Even, the two ends of crossbeam are overlapped on crossbeam clinch, and are fixedly connected with crossbeam clinch.Particularly, can by the area of plane compared with
Big sill is placed on two groups of balance shaft supports, forms the structure that crossbeam is overlapped on balance shaft support, makes crossbeam peace
Weighing apparatus bracing strut organically links together, compared with the past and due to the connection of crossbeam and crossbeam clinch, increased crossbeam with
Contact area between balance shaft support, changes the stress of balance shaft support, opens the force dispersion of balance shaft support, balance
The service life of bracing strut increases.
On horizontal level：It is tight by bolt with casting beam, vehicle frame that crossbeam load on balance shaft support puts reinforcement boss
Close link is integrated.On vertical position, balance shaft support side mounting surface, casting beam both sides and vehicle frame all carry bolt hole,
Balance shaft support, vehicle frame, casting beam ecto-entad are closely linked by bolt.2 points of the above, has fully ensured that balance shaft
Bonding strength between support and crossbeam, and make this construction more lightweight of balance shaft support.
Described leaf spring bindiny mechanism includes spring block, steel plate leaf spring and leaf spring fixing device, and steel plate leaf spring middle part passes through
