Problems solved by technology

During the driving process of the existing semi-trailer, the collision between the body and the frame is prone to vibration, and it is difficult for the general shock absorber to play a good shock absorbing effect. Some shock absorbing mechanisms that use rubber to achieve the shock absorbing effect are in the Rubber tends to generate heat during use, resulting in reduced service life

Abstract

The semitrailer frame comprises a frame body, a connecting beam is arranged on the side face of the frame body, a damping assembly is arranged at the bottom of the frame body, the damping assembly comprises a bin body on the outer side, a buffer seat is arranged in the bin body, an upper connecting piece is arranged at the bottom of the buffer seat, and a lower connecting piece is arranged at the bottom of the upper connecting piece. A fixing block is arranged at the bottom of the upper connecting piece, an elastic support is arranged on the lower side of the fixing block, an energy absorption piece is arranged in the elastic support, a heat conduction plate is connected to the bottom of the elastic support, and one end of the heat conduction plate penetrates through the bottom wall of the bin body and is connected with a plurality of metal sheets. A lateral supporting frame is arranged on the side face of the elastic support, a first fixing base is fixedly arranged on the lateral supporting frame, and a guide column is inserted into the first fixing base. The damping device is scientific and reasonable in structural design, stable in performance, excellent in damping effect and high in product reliability.

Description

technical field [0001] The invention relates to the technical field of semi-trailer equipment, in particular to a semi-trailer frame that can reduce the vibration of a vehicle body. Background technique [0002] A semi-trailer is a trailer in which the axles are placed behind the vehicle's center of gravity (when the vehicle is evenly loaded) and are equipped with hitches that transmit horizontal and vertical forces to the tractor. The semi-trailer is generally a three-axle semi-trailer, and its types are divided into 11-meter warehouse semi-trailer, 13-meter warehouse lantern, low-bed semi-trailer and many other types. It is a heavy-duty transportation vehicle connected with the semi-trailer head through a traction pin. Compared with "monolithic" vehicles, semi-trailers can improve the comprehensive economic benefits of road transportation. The transportation efficiency can be improved by 30-50%, the cost can be reduced by 30-40%, and the fuel consumption can be reduced b...
