Problems solved by technology
[0002] With the continuous development of the transportation industry, the user's requirement for the bearing surface of the semi-trailer is low and low, so the leaf spring with two axles and three axles installed on the semi-trailer is changed from the conventional upright to the reverse. Defects are also becoming more and more obvious: the leaf springs are reversely deformed, and the "U" bolts are easy to break, etc., which bring hidden dangers to driving safety.

Embodiment Construction
[0007] Such as figure 1 As shown, the present invention comprises a vehicle frame assembly 1 and a wheel axle assembly 2 arranged transversely, and a suspension assembly 3 is fixedly connected to the lower end of the longitudinal beam of the vehicle frame assembly 1, and a " U"-shaped bolt 4, on the "U"-shaped bolt 4, a reversed leaf spring 5 is arranged, and the front and rear ends of the reversed leaf spring 5 are rested on the corresponding suspension assembly 3 respectively.
[0008] The longitudinal beam lower wing plate 1 - 1 of the vehicle frame assembly 1 directly above the vehicle axle of the wheel axle assembly 2 is welded with a hard block 6 .

The invention provides a semitrailer with inverted plate springs and belongs to the technical field of the production of the semitrailer with various inverted plate springs. The semitrailer with the inverted plate springs comprises a frame assembly, a hanger bracket assembly and a plurality of axle assemblies, wherein the hanger bracket assembly is fixed at the lower end of a longitudinal beam of the frame assembly; U-shaped bolts are respectively hung on axles of the axle assemblies; inverted plate springs are respectively arranged on the U-shaped bolts; front and back two ends of the inverted plate springs are respectively placed on the corresponding hanger bracket assembly; a hard block is fixedly connected between a place right above the axles of the axle assemblies and the lower end of the longitudinal beam of the frame assembly; and the hard block can effectively limit the re-deformation of the plate springs. The plate springs and the U-shaped bolts no longer bear much gravity, thereby efficiently protecting the plate springs and the U-shaped bolts and achieving a purpose of safe driving.
Description
technical field [0001] The invention relates to the production technical field of transport semi-trailers with various leaf springs reversed. Background technique [0002] With the continuous development of the transportation industry, the user's requirement for the bearing surface of the semi-trailer is low and low. Therefore, the leaf spring with two axles and three axles installed on the semi-trailer is changed from the conventional upright to the reverse. Defects are also increasingly apparent: the leaf springs are reversely deformed, and the "U" type bolts are easy to break, etc., which have brought hidden dangers to driving safety. Contents of the invention [0003] The object of the present invention is to design a semi-trailer transport vehicle with reversed leaf springs which avoids reverse deformation of leaf springs and easy breakage of "U" bolts. [0004] The invention includes a reverse leaf spring semi-trailer transport vehicle, including a vehicle frame ass...
