Description

A kind of goods carrying vehicle becomes rigidity rubber equalizing-suspension device

Technical field

The utility model belongs to the automobile component design technical field, relates to the improvement of large-tonnage goods carrying vehicle equalizing-suspension device, especially adopts the equalizing-suspension device that becomes rigidity rubber lamination spring.

Background technology

At present the equalizing-suspension device of large-tonnage goods carrying vehicle extensively adopts steel spring formula balance suspension, and its structure is: the back of the body bow formula steel spring of vertically arranging is fixed on the balance shaft by U-bolt, two ends respectively with in, the rear driving axle sliding block joint; Balance shaft is installed on the big support of balance suspension by swivel bearing; Big support riveted joint of balance suspension or bolt are on chassis side rail.When load central, rear driving axle was inconsistent, steel spring played balanced compensated effect around the rotation of the center of balance shaft.Usually steel spring formula balance suspension also will be aided with six roots of sensation longitudinal rod, and promptly two ends are hinged on respectively on cross member of frame and middle drive axle or the rear driving axle, and the propulsive effort of wheel and brake-force transmission to vehicle frame, are controlled the motion and the position of two drive axles simultaneously.

In order to improve the fatigue life of suspension load and suspension parts, to need to increase the structural strength of the thickness of steel spring and sheet number, the big support of balance suspension, thereby caused the deadweight of balance suspension very big, 800 to 1000 kilograms.Balance shaft is that rigidity contacts with bearing between the big support of balance suspension, needs time-based maintenance.The rigidity of steel spring does not increase with load, has caused the ride comfort of empty wagons very poor.During longitudinal rod can not guarantee fully, the parallelism of rear driving axle, caused the abnormal tyre wear phenomenon to be difficult to solve.

Summary of the invention

In order to solve the technical matters that existing steel spring formula balance suspension exists better, the utility model provides a kind of later-model change rigidity rubber balance suspension, simple in structure, from heavy and light, non-maintaining, crossing ability good, can effectively improve ride comfort and balance suspension abnormal tyre wear problem.

The technical scheme that its technical matters that solves the utility model adopts is: a kind of change rigidity rubber balance suspension, mainly by saddle welding assembly on chassis side rail of riveted joint or bolt, with in, rear driving axle the equalizer welding assembly, suspension elastic element and the shock absorber of bolt between saddle welding assembly and equalizer welding assembly that are hinged by elastic ball constitute described suspension elastic element employing rubber lamination spring.

Described suspension elastic element preferably adopts the oblique rubber lamination spring of two V-type symmetric arrangement, and the upper end bolt is on saddle welding assembly, and the lower end bolt is on equalizer welding assembly.Two oblique rubber lamination springs utilize lever principle along longitudinal direction of car V-type symmetric arrangement, improve the crossing ability of vehicle.

Described rubber lamination spring is preferably rubber and steel plate vulcanizes from level to level to multilayer " sandwich " structure together, and it is very light to conduct oneself with dignity, and the characteristic that increases with load of tool rigidity, thereby has effectively improved the riding comfort of empty wagons.The central axis of oblique rubber lamination spring and the mutual out of plumb of each layer steel plate, the compression of comprehensive application rubber and shear deformation, the load of increase suspension.

Described rubber lamination spring also comprises an auxiliary rubber lamination spring, and by being arranged vertically, the upper end is fixed on the saddle welding assembly, lower end freedom when unloaded, and the lower end contacts with equalizer welding assembly when reaching setting load, and the beginning bearing load.Auxiliary rubber lamination spring is equipped with the nylon Crashworthy plate bottom, avoids causing auxiliary rubber lamination spring fatigue failure phenomenon with equalizer welding assembly bump.

Described equalizer welding assembly with in, rear driving axle can pass through the rubber bushing resilient connection, preferably the interference fit rubber bushing need not periodical maintenance, and can improve balance suspension abnormal tyre wear problem.

Change rigidity rubber balance suspension described in the utility model also can comprise positioning plate, and bolt prevents that described auxiliary rubber lamination spring and described equalizer welding assembly from slide relative taking place in contact process on described equalizer welding assembly.

Described shock absorber can adopt two hydraulic pressure cylinder type dampers, and upper end and described saddle welding assembly are hinged, and lower end and described equalizer welding assembly are hinged.
