Technical field
The utility model relates to the equalizing bar assembly of a kind of wheel crane with balance suspension, the particularly a kind of following wheel crane equalizing bar of 25-50 ton assembly that is used for.
Background technology
Wheel crane oneself requirement center of gravity is low, so that sling weight; Its working environment is also more abominable relatively, requires it to adapt to relatively poor road conditions; When wheel crane removes the lift heavy thing, its round-the-clock carrying complete vehicle weight.Wheel crane is simple with balance shaft assembly requirement self structure, center of gravity is low, the adaptation road conditions are poor, it is big to carry, adapt to round-the-clock being fully loaded with.The conventional balanced axle assembly adopts whole through or split type, complex structure, and center of gravity is higher, and vehicle economy descends, and service expenditure is high, be not to adapt to round-the-clock oepration at full load; The conventional balanced axle assembly all can't guarantee the carrying of this kind vehicle.
Summary of the invention
The technical matters that the utility model will solve is: a kind of wheel crane equalizing bar assembly is provided, has been applicable to 25-50 ton wheel crane, himself is simple in structure, center of gravity is low, the adaptation road conditions are poor, it is big to carry, it is round-the-clock fully loaded to adapt to.Last lower thrust rod in the cancellation balance suspension assembly system is directly replaced by equalizing bar, and is simple in structure, and then center of gravity is low, connects the both sides equalizing bar by being communicated with mandrel, guarantees that its obstacle climbing ability is strong.
In order to solve the problems of the technologies described above, wheel crane equalizing bar assembly mainly comprises equalizing bar 4, balance axle bed 3, mandrel sleeve 2, is communicated with mandrel 12.
Said wheel crane equalizing bar assembly serves as the assembling parent with equalizing bar 4, and oil sealing 13, axle sleeve 14 are pressed in the equalizing bar 4; Balance axle bed 3 is connected through thru-bolt 16, hexagonal nut 17, spring chair 18 prepackages with fixing lock dog 10, and lock bolt 15 is installed on the balance axle bed 3; Equalizing bar after installing 4, balance axle bed 3 are connected through mandrel sleeve 2 with pad 11, with thru-bolt 16, hexagonal nut 17, spring chair 18 with fixedly lock dog 10 is fixing.The ball seat 8 of packing in the equalizing bar 4 two ends centre holes; Fix with hexagonal nut 21 with hexagonal bar iron 19, spring chair 20; Load onto spherical axle sleeve 5, dust boot 6, nut 7, equalizing bar bearing pin 9 and spring cotter 23, be communicated with mandrel 12 and pack in the mandrel sleeve 2, the equalizing bar that installs 4 assemblies are connected; Mandrel sleeve 2 other ends are loaded onto tightening cover 1, pin with spring cotter 23; Load onto lubrication adapter 22.
Said connection mandrel 12 is through equalizing bar 4, balance axle bed 3, the 2 supporting uses of mandrel sleeve, and balance axle bed 3 connecting panel spring supports are on equalizing bar 4, and equalizing bar 4 two ends are connected with vehicle bridge.
Balance axle bed 3 is connected through lock bolt 15 with leaf spring, and the leaf spring two ends are connected with the vehicle frame bottom surface.
Said equalizing bar adopts inblock cast, and its intensity is fine.
For the ease of dismounting, each region of interest all adopts spring cotter, bolted connection, and each joint part adopts oil lubrication.
The beneficial effect of the utility model is: compact conformation, load-carrying is big, performance good, simple in structure, be convenient to produce and install.Two equalizing bars connect through the intermediate connection mandrel, can rotate therebetween, and the jerk value of back axle increases in making, thereby adapts to relatively poor road conditions; Adopt equalizing bar directly to be connected with middle back axle, lower thrust rod in the cancellation, thus the car load center of gravity is reduced.Equalizing bar adopts foundry goods, and its load carrying ability improves, and adapts to load-carrying at full capacity.
