Embodiment Construction

[0010] Such as figure 1 as shown, figure 1 Add upper and lower L-shaped reinforcement beams 1 to the longitudinal beam 4 of the chassis body and lengthen to the tail end of the longitudinal beam 4; add a crossbeam 2 at the tail near the chassis body to connect with the longitudinal beam 4 of the chassis body on the abdomen; The afterbody of the longitudinal beam 4 of the chassis body is equipped with an overturning shaft holder 3, and the through shaft centerline of the overturning shaft holder is perpendicular to the longitudinal beam 4 of the chassis body. Such as figure 2 As shown, a side limiting block 5 is provided on one side of the longitudinal beam 4 of the chassis body, and on the upper front of the installation position of the leaf spring 6 . The side limit block 5 is installed in the middle, which improves the operation stability. In the dump truck without subframe of the present invention, the turning device is fixed on the turning shaft fixing seat of the chas...

Abstract

The invention relates to a sub-frameless self-demounting car chassis assembly which comprises a chassis body and is characterized in that L-shaped stiffening beams are installed both above and below a longeron of the chassis body; the L-shaped stiffening beams extend to the tail end of the longeron; a crossbeam is arranged additionally at the position near the tail of the chassis body; the crossbeam is connected with the longeron of the chassis body on a rearwards face; the tail of the longeron of the chassis body is equipped with a trip shaft fixing base; and the center line of a through shaft of the trip shaft fixing base is vertical to the longeron of the chassis body. The sub-frameless self-demounting car chassis assembly has the advantages that the low matching gravity center, the hoisting stabilization, the high reliability, the stable production technology and the mature and reliable technology of the whole car can be ensured and the obvious advantages on the quality and the performance can be taken.

Description

1. Technical field: [0001] The invention relates to a chassis assembly of a dump truck without an auxiliary frame. 2. Background technology: [0002] Heavy-duty dump trucks are mainly composed of ordinary dump truck chassis, sub-frame, box body, hydraulic system, etc. Due to the harsh operating environment and complex working conditions of engineering dump trucks, it is increasingly required to improve the reliability of the entire vehicle and the stability of lifting operations. For heavy-duty dump trucks with sub-frames, the body turning system and hydraulic system are fixedly installed on the sub-frames. The vehicle has a high center of gravity, a large curb weight, and poor stability when driving and lifting. It is suitable for market segments. Non-sexual characteristics. 3. Contents of the invention: [0003] The purpose of the present invention is to provide a chassis assembly of a dump truck without sub-frame in order to reduce the center of gravity of the whole v...
