The invention discloses a transfer wheel device for a combined semitrailer. The device comprises a supporting leg shell assembly, a lifting leg assembly and a turning plate type pressing mechanism, the supporting leg shell assembly is fixed on the second section of a semitrailer walking chassis body, a first fixing hole is formed in the supporting leg shell assembly, the lifting leg assembly is arranged in the supporting leg shell assembly in a penetrating manner, the lifting leg assembly comprises supporting legs and transfer wheels arranged at the bottoms of the supporting legs, a pluralityof vertically-distributed second fixing holes are formed in the supporting legs, pin shafts are arranged in the holes, the lifting leg assembly can be folded and unfolded through cooperation of the pin shafts and the fixing holes, and therefore the lifting leg assembly can be used as rear supporting wheels of a first section and second section assembly when the second section and the third sectionof the combined semitrailer are separated or in butt joint; and the turning plate type pressing mechanism is fixedly arranged at the upper end of the supporting leg shell assembly, the height adjusting function of the lifting leg assembly is achieved by pressing the supporting legs downwards, then separation and butt joint of the semitrailer are completed in an assisted mode, and the transfer wheel device is compact in structure and small in occupied space.
Description
Technical field[0001]The invention belongs to the field of automobile manufacturing, and particularly relates to a transfer wheel device for a combined semi-trailer.Background technique[0002]The existing semi-trailer running underframes are all integral, without sections. Under the towing of the tractor, road driving and transportation can be carried out no matter it is empty or full. The modular combined type (section III or above) super-long semi-trailer is still relatively rare in China, which is not convenient for road driving and transportation, and it is necessary to switch between the length and the short state when the section is transported.[0003]In order to facilitate the long and short state switching of the semi-trailer: auxiliary section II and section III separation and docking; used as the rear support wheel of the I and II section combination, a transfer wheel device is designed, and the transfer wheel device has a height adjustment function.Summary of the invention[...
