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 present invention belongs to the semi-trailer technology, and in particular to a semi-trailer compartment and the bottom support structure at the head connection and the use of the same.Background technique[0002]The semi-trailer is a trailer when the axis is placed in the center of vehicle (when the vehicle is uniformly loaded), and is equipped with a trailer that can transmit a flat and vertical force to the cougon of the tractor. The semi-trailer is a heavy-duty transportation vehicle connected to the semi-trailer head, and the semi-trailer can improve the comprehensive economic benefits of road transport compared to the "monomer" car. Transportation efficiency can be increased by 30-50%, cost reduction is 30-40%, and fuel consumption is 20-30%.[0003]The semi-trailer support structure is a special component of the semi-trailer compartment and is installed at the bottom of the half-trailer compartment. The current semi-trailer support structure includes sup...
