Abstract

The invention discloses a semitrailer carriage and vehicle head joint bottom supporting structure. The supporting structure comprises a connecting plate, a support and a lifting mechanism, and the lifting mechanism is installed between the connecting plate and a supporting plate; two first vertical plates which are oppositely arranged are fixed to the upper surface of the connecting plate, and twosecond circular through holes are formed in the surface of each first vertical plate; a first shaft rod, a first connecting rod, a third connecting rod, a fourth connecting rod and a fifth shaft rodof the lifting mechanism form a rhombus structure; and a connecting cylinder is fixed to the second shaft rod in a penetrating mode, thread is formed in the inner wall of the connecting cylinder, anda threaded shaft is installed in the connecting cylinder. The fit design of the connecting rod and the threaded shaft makes the lifting movement of the supporting plate achieved by rotating a handle connected to the threaded shaft, so a speed-changing gear box is not used, the whole structure is compact, occupies no space, and can achieve the stable supporting effect; and the structure is compact,is easy to operate, and is suitable for supporting the bottom of the joint of the semitrailer carriage and the semitrailer head.

Description

technical field [0001] The invention belongs to the technical field of semi-trailers, and in particular relates to a bottom support structure at the joint between a semi-trailer compartment and a vehicle front and a method for using the same. Background technique [0002] A semi-trailer is a trailer whose axle is placed behind the vehicle's center of gravity (when the vehicle is evenly loaded) and is fitted with a hitch that transmits horizontal and vertical forces to the tractor. A semi-trailer is a heavy-duty transport vehicle connected to the head of the semi-trailer through a traction pin. Compared with a "single-body" car, a semi-trailer can improve the comprehensive economic benefits of road transportation. The transportation efficiency can be increased by 30-50%, the cost can be reduced by 30-40%, and the fuel consumption can be reduced by 20-30%. [0003] The supporting structure of the semi-trailer is a special part of the semi-trailer, which is installed at the bo...
