Description

A kind of bont of autotruck rear trunnion
(1) technical field
The utility model relates to a kind of bont of heavy motor vehicle 6 * 2 rear trunnions, belongs to the Heavy Truck Driveline technical field.
(2) background technology
The effect of the rear trunnion bont of HD truck is, under zero load or underload rear trunnion mentioned, and both can reduce Tyte Wear, reduces oil consumption again, improved the ride comfort of car load simultaneously; In addition, owing under zero load or light load, rear trunnion is mentioned, increased drive axle ground-surface pressure has been puted forth effort, thereby improved wheel and ground-surface adhesion value.Usually, air suspension is adopted in the lifting of rear trunnion, by air bag rear trunnion is promoted, but is subjected to the lower restriction of air suspension internal gas pressure, and hoisting capacity is relatively poor, influences the performance of transmission system.
(3) summary of the invention
The utility model is at the deficiencies in the prior art, provides that a kind of hoisting capacity is strong, the rear trunnion bont of dependable performance, easy to operate heavy motor vehicle Swing Arm Type Balanced Suspension.
The utility model is achieved through the following technical solutions.
This device mainly comprises hydraulic actuating cylinder, rotating shaft, the thrust hydraulic cylinder arm, rotating shaft thrust arm, hold-down arm, balance shaft and balance oscillating arm, wherein, hydraulic actuating cylinder is packed on the vehicle frame by the hydraulic actuating cylinder bracing frame, rotating shaft is packed on the vehicle frame by rotary shaft rack, the midway location of rotating shaft is fixed with the thrust hydraulic cylinder arm, the two ends of rotating shaft are fixed with rotating shaft thrust arm, in thrust hydraulic cylinder arm both sides the hold-down arm that can rotate around the shaft is housed also, the other end of thrust hydraulic cylinder arm is connected with the push rod of hydraulic actuating cylinder, the other end of rotating shaft thrust arm places the top of balance oscillating arm, and the other end of hold-down arm is connected with hydraulic cylinder leg; Balance shaft is packed on the vehicle frame, and balance oscillating arm can rotate around balance shaft, and an end of balance oscillating arm is connected with an end of pivot shaft, the rear end sliding block joint of the other end and steel spring.
On the described rotating shaft thrust arm roller is housed.
The utility model adopts swing arm balance suspension formula structure, makes the interior pressure of hydraulic actuating cylinder be much higher than the pressure of air suspension internal gas pressure.Under the effect of hydraulic actuating cylinder, rotating shaft thrust arm is pressed in the swing arm by roller, the rich balance shaft rotation of swing arm, and hoisting capacity increases.Hydraulic actuating cylinder can provide higher power, rotating shaft, thrust hydraulic cylinder arm, rotating shaft thrust arm can be delivered to hydraulic cylinder power on the balance oscillating arm, the effect of hold-down arm is the supplemental support rotating shaft, the normal force of support hydraulic cylinder thrust arm countershaft, the effect of balance shaft and balance oscillating arm are the effect lifting pivot shafts by external force.Roller be housed be the relative friction forces when reducing rotating shaft thrust arm and act in the swing arm on the rotating shaft thrust arm.Principle of work is as follows: hydraulic actuating cylinder is under higher pressure effect, and the hydraulic actuating cylinder push rod promotes the thrust hydraulic cylinder arm, and the rotating shaft rotation drives the rotation of rotating shaft thrust arm, presses down the equilibrium arm near the steel spring side, and equilibrium arm rotates around balance shaft, and back pivot shaft is raised.It is big to the utlity model has hoisting capacity, dependable performance, advantage such as reasonable in design, easy to use.
(4) description of drawings
The structural representation that Fig. 1 does not promote for back axle among the utility model embodiment.
Fig. 2 is the structural representation after back axle promotes among the utility model embodiment.
Fig. 3 is the front view of the utility model pivot structure scheme drawing.
Fig. 4 is the right elevation of the utility model pivot structure scheme drawing.
Wherein, 1, rotary shaft rack, 2, rotating shaft, 3, the thrust hydraulic cylinder arm, 4, rotating shaft thrust arm, 5, roller, 6, balance oscillating arm, 7, hold-down arm, 8, hydraulic actuating cylinder, 9, the hydraulic actuating cylinder bracing frame, 10, balance shaft, 11, pivot shaft.
(5) specific embodiment
Embodiment, as accompanying drawing 1,2,3, shown in 4, this device mainly comprises hydraulic actuating cylinder 8, rotating shaft 2, thrust hydraulic cylinder arm 3, rotating shaft thrust arm 4, hold-down arm 7, balance shaft 10 and balance oscillating arm 6, wherein, hydraulic actuating cylinder 8 is packed on the vehicle frame by hydraulic actuating cylinder bracing frame 9, rotating shaft 2 is packed on the vehicle frame by rotary shaft rack 1, the midway location of rotating shaft 2 is fixed with thrust hydraulic cylinder arm 3, the two ends of rotating shaft 2 are fixed with rotating shaft thrust arm 4, the hold-down arm 7 of 2 rotations around the shaft also is housed in thrust hydraulic cylinder arm 3 both sides, the other end of thrust hydraulic cylinder arm 3 is connected with the push rod of hydraulic actuating cylinder 8, the other end of rotating shaft thrust arm 4 places the top of balance oscillating arm 6, and the other end of hold-down arm 7 is connected with hydraulic actuating cylinder 8 supports; Balance shaft 10 is packed on the vehicle frame, and balance oscillating arm 6 can rotate around balance shaft 10, and an end of balance oscillating arm 6 is connected with an end of pivot shaft 11, the rear end sliding block joint of the other end and steel spring.On the rotating shaft hold-down arm roller is housed.In the time of need mentioning back pivot shaft 11, operating hydraulically operated cylinder 8 work, the push rod of hydraulic actuating cylinder 8 stretches out, and promotes thrust hydraulic cylinder arm 3, driving rotating shaft 2 rotates, rotating shaft thrust arm 42 is rotated around the shaft, wait turn over certain angle after, the roller 5 of rotating shaft thrust arm 4 is pressed onto balance oscillating arm 11 near steel spring one ends, rotating shaft thrust arm 4 continues rotation, the pressure of 5 pairs of balance oscillating arms 6 of roller increases gradually, and the load of pivot shaft 11 is gradually little, the rear overhang rack steel plate deformed; When the load on the pivot shaft is reduced to zero, not redeformation of steel spring; Hydraulic actuating cylinder works on, and balance oscillating arm 6 rotates around balance shaft 10, and pivot shaft promotes, because not redeformation of steel spring, vehicle frame also begins to raise; When pivot shaft rose to design height, control system made hydraulic efficiency pressure system quit work, the hydraulic actuating cylinder locking, and the purpose that promotes back axle realizes.
