Abstract
A hinged pull rod type balancing suspension assembly for a heavy duty car belongs to the field of autotruck manufacturing technology. The balancing suspension assembly is characterized in that an extending end of a counterbalance shaft and a shaft hole of a support frame are assembled and fixed as a whole; the upper part of the support frame and the ends of thrusting rod seats are fixedly connected; bi-metal sleeves are mounted in two plate spring seats and are in slide fit with the counterbalance shaft; the thrusting rod seats are fixedly connected with the main bracket body through bolts; and the thrusting rod seats are hinged and fixed through pull rods. The utility model has the beneficial effects 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 through a bush cover is changed into hinged pull rod type fixation with the main bracketbody; and the support frame and the ends of the thrusting rod seats are fixedly connected, thereby simplifying the structure, changing the bending force into the pulling force, and enhancing the adaptability and load-bearing capacity.
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: the hinged rod-pulling type balance suspension of a kind of heavy motor vehicle 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 bracing frame (4) axis hole mount are one, captive joint with thrust pole seat (5) end in bracing frame (4) top, dress bimetal liner and balance shaft (3) bearing fit in two spring blocks (2), thrust pole seat (5) is captiveed joint with main body rack (1) by bolt, and two thrust pole seats (5) are all by pull bar (6) hinged securement.
Main body rack (1) boss is spacing cooperation of pegging graft with thrust pole seat (5) fillister joint position.
The beneficial effects of the utility model are: make balance shaft not be subjected to alternating bending power, only be subjected to pulling force and shearing, former adapter shaft is fixed with FE Tiler and main body rack, changing hinged rod-pulling type and main body rack into fixes, bracing frame is captiveed joint with the thrust pole seat end, play simplified structure like this, bending force is become pulling force, increase comformability and load-carrying capacity.
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, 2 is two spring blocks, the 3rd, balance shaft, the 4th, bracing frame, the 5th, thrust pole seat, the 6th, pull bar.
The both sides main body rack that is fixed on the vehicle frame is connected by adapter shaft, use hinged rod-pulling type bonded assembly technical scheme instead, balance shaft (3) one ends and main body rack (1) are fitted together; Another external part cooperates with bracing frame (4) axis hole, captives joint with thrust pole seat (5) end with bolt in bracing frame (4) top, and thrust pole seat (5) is captiveed joint with both sides main body rack (1) respectively with bolt.Crossbeam is hinged pull bar (a 6) formula.Dress bimetal liner and balance shaft (3) bearing fit in the two end plates spring abutment (2).Like this, balance shaft is not subjected to alternating bending power, only is subjected to pulling force and shearing.
Main body rack (1) thrust pole seat (5) is a bolted connection, 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 is that thrust pole seat (5) is formed with hinged pull bar (6), and the side, two ends is provided with the fixed position of installed thrust bar.
Claims (2)
1, the hinged rod-pulling type balance suspension of a kind of heavy motor vehicle assembly, it is characterized in that: balance shaft (3) external part and bracing frame (4) axis hole mount are one, captive joint with thrust pole seat (5) end in bracing frame (4) top, dress bimetal liner and balance shaft (3) bearing fit in two spring blocks (2), thrust pole seat (5) is captiveed joint with main body rack (1) by bolt, and two thrust pole seats (5) are all by pull bar (6) hinged securement.
2, the hinged rod-pulling type balance suspension of a kind of heavy motor vehicle according to claim 1 assembly is characterized in that: main body rack (1) boss is spacing cooperation of pegging graft with thrust pole seat (5) fillister joint position.
