Abstract
The utility model relates to a hydraulic hanging device for a large-journey vehicle, which comprises a hanging unit connected with a vehicle frame and vehicle axles connected with the hanging unit. The hanging unit comprises a hanging frame, a balance arm and a ball hinge support oil cylinder. The hanging frame is connected with the vehicle frame in rotating mode, and two end portions of the balance arm are respectively connected with the hanging frame and the vehicle axles in rotating mode. The ball hinge support oil cylinder comprises an oil cylinder body, a piston rod matched with the oil cylinder body and an inner ball head connected with the end portion of the piston rod, the end portion of the oil cylinder body is connected with the hanging frame, and the inner ball head is connected with the balance arm. The hydraulic hanging device has the advantages of being small in size, large in hanging lifting journey, small in size, light in weight, large in bearing capacity, reasonable in integral structure, convenient to install, maintain and the like.
Description
Technical field
the utility model relates to a kind of big stroke vehicle that is applicable to the big part of carrying, particularly relates to a kind of big stroke vehicle and uses hydraulic lift hitch.
Background technology
suspension gear is one of important composition of engineering truck; Mainly flexibly couple together vehicle frame or vehicle body and wheel; Be used for a shear force and the moment of transfer function between wheel, vehicle frame, to relax the impact that uneven road surface passes to vehicle frame.
are present; The used hydraulic lift hitch of known engineering transport trolley mainly is to be formed by parts such as hanger bracket, hanging oil cylinder, equilibrium arm and component assembly; Its hanging oil cylinder two supported ends have all adopted oscillating bearing to connect hanger bracket and equilibrium arm; But adopt two ends oscillating bearing restriction to a certain degree the stroke of hydraulic ram, thereby make the lifting travel of whole suspension gear limited.
Summary of the invention
The purpose of
the utility model provides a kind of big stroke vehicle and uses hydraulic lift hitch.
For achieving the above object, the technical scheme that the utility model adopts is:
a kind of big stroke vehicle is used hydraulic lift hitch; It comprises the suspension unit that is connected with carriage frame, the vehicle bridge that is connected with described suspension unit; Described suspension unit comprises: hanger bracket, equilibrium arm and ball pivot support cylinder; Described hanger bracket rotates with described carriage frame and is connected; The both ends of described equilibrium arm rotate with vehicle bridge with described hanger bracket respectively and are connected; Described ball pivot support cylinder comprises cylinder block, the piston rod that matches with described cylinder block and the interior bulb that is connected described piston rod end, and the end of described cylinder block is connected with described hanger bracket, and described interior bulb is connected with described equilibrium arm.
preferably the end of described cylinder block are connected with described hanger bracket through oscillating bearing.
preferably, described hanger bracket rotates with described carriage frame through pivoting support bearing and is connected.
Because the technique scheme utilization, the utility model compared with prior art has advantage:
(1), the suspension oad is little;
(2), the suspension lifting stroke is big;
(3), volume is little in light weight;
(4), load-carrying capacity is big;
(5), reasonable integral structure is convenient to install, maintains, keeped in repair.
Description of drawings
accompanying drawing 1 is the structural representation of the utility model.
wherein: 1, hanger bracket; 2, oscillating bearing; 3, cylinder block; 4, piston rod; 5, interior bulb; 6, equilibrium arm; 7, carriage frame; 8, ball pivot support cylinder; 9, pivoting support bearing; 10, suspension unit.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described:
a kind of big stroke vehicle as shown in the figure is used hydraulic lift hitch, and it comprises the suspension unit 10 that is connected with carriage frame 7, the vehicle bridge (not shown) that is connected with suspension unit 10.
in the present embodiment: suspension unit 10 comprises: hanger bracket 1, equilibrium arm 6 and ball pivot support cylinder 8; Its annexation is: hanger bracket 1 rotates through pivoting support bearing 9 with carriage frame 7 and is connected; Pivoting support bearing 9 drives hanger bracket 1 can turn round the function that can go up and down again to reach not only; The both ends of equilibrium arm 7 rotate with vehicle bridge with hanger bracket 1 respectively and are connected.
ball pivot support cylinder 8 comprises: cylinder block 3, the piston rod 4 that matches with cylinder block 3 and the interior bulb 8 that is connected piston rod 7 ends; Its annexation is: the end of cylinder block 3 is connected through oscillating bearing 2 with hanger bracket 1, and interior bulb 8 is connected with equilibrium arm 6.
for a vehicle, each vehicle bridge all disposes a corresponding suspension unit 10, realizes separately or simultaneously automatic compensation function.
Below set forth the work engineering of present embodiment down:
vehicle is through roughness pavement the time; Oil circuit can inject hydraulic oil or make hydraulic oil get back to oil circuit from cylinder block 3 in cylinder block 3; Make piston rod 4 stretch, contract and drive the rotation up and down of equilibrium arm 6; The platform plane and the ground-surface height that guarantee vehicle remain unchanged, and to adapt to the ground-surface situation, reach the automatic compensation function of suspension unit 10.
like this; Because the ball pivot support cylinder 8 of this suspension unit 10; Add that suspension unit 10 each swivel point position dimension count carefully repeatedly, the swivel point location arrangements is reasonable, then this suspension unit 10 is compared with suspension in the past, on lower hanger bracket 1; The hanging oil cylinder stroke is big, makes whole suspension unit 10 have advantages such as oad is little, volume is little, the suspension travel scalable is big.
the foregoing description is only for explaining the technical conceive and the characteristics of the utility model; Its purpose is to let the personage who is familiar with this technology can understand content of the utility model and enforcement according to this, can not limit the protection domain of the utility model with this.All equivalences of being done according to the utility model spirit change or modify, and all should be encompassed within the protection domain of the utility model.
