Background technology
Suspension gear is one of major part of trailer, and usually mode and the trailer crossbeam by welding links together, and it mainly acts on is that power and moment the road surface acts on the wheel all is delivered on the vehicle body, with the cruising of assurance trailer.
At present, the suspension gear of generally acknowledging in the trailer industry is No. 00228953.9 disclosed a kind of superimposed trailer suspension gear of Chinese utility model patent, referring to Fig. 1, Fig. 2, it comprises the front frame that can be welded on the trailer crossbeam, medium-height trestle, after poppet, be installed on the equalizing bar in the medium-height trestle, movable preceding, steel plate spring assembly between after poppet and the equalizing bar, the axletree axis body is fixed on pressing plate on the steel plate spring assembly, the axletree upper bracket, the axletree lower bracket, carriage and U-bolt, carriage with before, the linkage connector that after poppet couples together, regulate connecting rod, stationary links.
The suspension gear parts of this form are more, connecting rod will or be regulated and linkage connector and forward and backward support and equalizing bar are finished by leaf spring, carriage, stationary links in the location of axletree, fitting process is complicated, but also need could guarantee that each is parallel to each other by adjusting the adjusting connecting rod, the head of linkage connector is equipped with rubber coating, after the rubber coating wearing and tearing, regulates connecting rod or changes gum cover as untimely adjustment, originally each that is parallel to each other spool will depart from, thereby aggravated Tyte Wear.So the trailer that is equipped with this suspension gear in use can increase the work capacity of maintenance, increase service expenditure.
Summary of the invention
The purpose of this utility model provides a kind of trailer equilibratory suspension, this apparatus structure is simple, assembling easily, avoid adjusting in the use and safeguard.
The technical solution of the utility model is: front frame, medium-height trestle, after poppet are welded on the trailer crossbeam; The front portion of equalizing bar is a skateboard structure, and the rear portion is an axle sleeve structure, is installed in the medium-height trestle by the equalizing bar Assembly of pin; Steel plate spring assembly is a front end grasswort formula, and front end is connected with front frame, equalizing bar rear portion by the steel spring Assembly of pin, and the rear end is installed in equalizing bar front portion, the after poppet; Steel plate spring assembly is connected with the axletree axis body by pressing plate, axletree upper bracket, U-bolt assembly and axletree lower bracket.
When trailer when uneven road surface travels, rely on the swing of equalizing bar to realize the uniform distribution of each load on axle journals, thereby reach the purpose of balance.
The utility model is compared with existing suspension gear, not only save linkage connector, regulated connecting rod, stationary links and carriage, and front frame and medium-height trestle be not because there has been the installation site of linkage connector and stationary links, it is simple that structure also becomes, simultaneously assembling with use in do not need to regulate connecting rod and guarantee the parallel of each by adjusting yet, easy to operate.
The beneficial effects of the utility model are, apparatus structure is simple, low cost of manufacture, assembling easily, avoid adjusting in the use and safeguard.
