Abstract
A cross beam type balancing suspension assembly of a heavy duty car is characterized in that the extending end of a counterbalance shaft is assembled with the shaft hole of a support frame; the upperpart of the support frame is fixedly connected with the end of a cross beam through a bolt; bi-metal sleeves are mounted in two plate spring seats and in slide fit with the counterbalance shaft; the cross beam is fixedly connected with the main bracket body through a bolt; and the cross beam adopts an integral I-shaped beam. The utility model has the advantages that the counterbalance shaft can not bear an alternative bending force, and only bear a pulling force and a shearing force; the fixation between the original connecting shaft and the main bracket body is changed into the fixation between the cross beam and the main bracket body; and the support frame and the end of the cross beam are fixedly connected, thereby simplifying the structure and enhancing the rigidity and load-bearing capacity. Therefore, the utility model solves the problem that the shaft, the bearing, the bracket and the bolt are easily damaged, and the like in the original structure.
Description
Technical field
The utility model belongs to autotruck manufacturing technology field, relates to a kind of improvement of truck suspension structure.
Background technology
The balance suspension assembly of heavy motor vehicle use now has multiple pattern, if any FE Tiler compression type adapter shaft, the solid forging cambered axle is arranged, and also has the balance suspension assembly of the fricton-tight bearing of separating stent-graft etc.Their common feature is: the axle at supporting steel plate spring position is the projecting shaft structure.Support this and the fixing both sides main body rack of vehicle frame in addition, displacement and distortion are arranged under local function mutually.Therefore stent size weight is done very greatly.
Summary of the invention
The purpose of this utility model is: a kind of heavy motor vehicle cross beam type balance suspension assembly is provided, and it has solved the stressed diastrophic problem of balance shaft.
The technical solution of the utility model is: balance shaft (3) external part and the assembling of bracing frame (4) axis hole, captive joint with crossbeam (5) end with bolt in bracing frame (4) top, dress bimetal liner and balance shaft (3) bearing fit in two spring blocks (2), crossbeam (5) is captiveed joint with main body rack (1) by bolt, and crossbeam is the integral type H-girder.
Main body rack (1) boss is spacing cooperation of pegging graft with crossbeam (5) fillister joint position.
The beneficial effects of the utility model are: balance shaft is not subjected to alternating bending power, only is subjected to pulling force and shearing.Former adapter shaft is fixed with FE Tiler and main body rack, changed into crossbeam and main body rack is fixed, bracing frame is captiveed joint with beam-end, plays simplified structure like this, increases rigidity and load-carrying capacity.Quality problems such as the axle that the solution original design exists is easily broken, bearing is frangible, support easily splits, the spindle nose bolt is easily broken.
Description of drawings:
Fig. 1 is the utility model structure office cutaway view.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
As shown in the figure, the 1st, main body rack, the 2nd, spring block, the 3rd, balance shaft, the 4th, bracing frame, the 5th, crossbeam.
Former adapter shaft is fixed with FE Tiler and main body rack, and it is fixing with main body rack (1) to change crossbeam (5) into, and bracing frame (4) is captiveed joint with crossbeam (5) end, plays simplified structure like this, increases rigidity and load-carrying capacity.
Main body rack (1) is a bolted connection with crossbeam (5), and face of joint has positive stop lug boss and groove.
Establish oil reservoir dress bimetal liner in the spring block (2), have the double-U-shaped bolt position of installation, crossbeam (5) is a whole i-shaped beams, and the side, two ends is provided with the fixed position of installed thrust bar.
Claims (2)
1, a kind of heavy motor vehicle cross beam type balance suspension assembly, it is characterized in that: balance shaft (3) external part and the assembling of bracing frame (4) axis hole, captive joint with crossbeam (5) end with bolt in bracing frame (4) top, dress bimetal liner and balance shaft (3) bearing fit in two spring blocks (2), crossbeam (5) is captiveed joint with main body rack (1) by bolt, and crossbeam is the integral type H-girder.
2, a kind of heavy motor vehicle cross beam type balance suspension assembly according to claim 1 is characterized in that: main body rack (1) boss is spacing cooperation of pegging graft with crossbeam (5) fillister joint position.
