One is fixedly connected with rear two bridge of trailer also by bolt, and the steel plate leaf spring middle-end and spindle bearing hub pass through bolt and connect
It connects, the steel plate leaf spring position-limit mechanism is fixedly mounted and erecting bed lower end surface, is vertically positioned at steel plate under normally travel state
Right above spring, and do not contacted with steel plate leaf spring.
Preferably, the steel plate leaf spring position-limit mechanism longitudinal cross-section is " towering " structure, and is made of 65 manganese spring steel plates.
Preferably, the bolt uses U-bolt, and constitutes for alloy steel.
Be using the beneficial effect of above technical scheme: the single-point hangs position-limit mechanism, improves trailer after lifting,
The angular dimension that single-point is hanging to Trailer type frame for use in vehicle changes, and encounters bumpy road, adds the amplitude of fluctuation of width leaf spring, increases
The service life of leaf spring, and the safety of trailer transport is exacerbated, by steel plate leaf spring position-limit mechanism trailer is being transported
Safety is improved on the way, and the production of steel plate leaf spring position-limit mechanism is simple, suitable production and application low in cost.
Secondly, steel plate leaf spring position-limit mechanism is made of 65 manganese spring steel plates, and it is more rigid relative to channel steel, so utilizing limit
The rigid of position plate, limits the swing that single-point is hung in operation and hoisting process.
This, bolt use U-bolt, and for alloy steel constitute so that steel plate leaf spring mutually rub it is closer.
