Abstract

The utility model relates to a farm trailer which comprises a wagon box, a vehicle frame, a wheel shaft, a draw beam and a draw ring. The utility model is characterized in that the draw beam arranged on the lower part of the wagon box is connected with the wheel shaft through a U-shaped clamp. A damping arcualia is arranged between the middle part of the draw beam and the vehicle frame, and a slide shaft is arranged in the connected position of the arcualia with the draw beam. Because the damping arcualia is arranged between the middle part of the draw beam and the vehicle frame and the slide shaft is arranged in the connected position of the arcualia with the draw beam, the impact load of the trailer load on the rear draw components of a tractor is reduced, the problem that the deformation of the arcualia at the wheel shaft part causes rearward shift of the wheel shaft and rearward shift of the draw beam is solved, and the deformation and damage of a draw pin, the vehicle frame, etc. are avoided.

Description

Farm trailer

Technical field

The utility model relates to the farm vehicle technical field, particularly a kind of farm trailer.

Background technology

Farm trailer is the major equipment that the agricultural four-wheeled tractor traction of China is transported, its draw beam is fixedly installed on the front end of railway carriage, its shortcoming is that the connecting portion of trac. and farm trailer will bear load-carrying load, tractive force and friction force simultaneously, is subjected to the destruction of shearing force easily and ruptures; Owing to be to fix by the mode of welding between vehicle frame and the draw beam, vehicle frame distortion and break beam accident and trac. rear haulage spare phenomenon of rupture often appear.

Goal of the invention

The connecting portion that the purpose of this utility model provides a kind of trac. and farm trailer is not easy to rupture and vehicle frame is not easy to deform and the farm trailer of disconnected beam.

The utility model is to realize like this, it comprises railway carriage, vehicle frame, wheel shaft, draw beam and eye hitch, it is characterized in that the draw beam that is arranged on the railway carriage bottom is connected with wheel shaft by U type folder, between the middle part of draw beam and vehicle frame, be provided with the arculae that is used for damping, be provided with slide shaft at arculae and draw beam connection location.

The utility model is owing to be provided with the arculae that is used for damping between the middle part of draw beam and vehicle frame, be provided with slide shaft at arculae and draw beam connection location, subdued the impact load of trailer load to trac. rear haulage parts, solved owing to move behind the wheel shaft that the distortion of wheel axial region arculae causes, draw beam with after the problem of moving, and can avoid part distortion and damages such as towing pin, vehicle frame.
