a sub-frame

Abstract

The invention provides an auxiliary frame. A main body is of a welded frame structure. The auxiliary frame comprises an L-shaped left / right beams oppositely arranged inwards as well as a front / right front bracket and a left / right rear bracket respectively welded on the L-shaped left / right beams, wherein a rear cross beam is welded on the bottom of the left / right rear bracket; the left / right beams comprise horizontal plates and vertical plates; the horizontal plates and the vertical plates are respectively provided with a mounting hole, and the mounting holes are used for realizing connection of a hanger bracket and the frame by virtue of bolting. The L-shaped left / right beams and the front and rear brackets are welded so as to form the auxiliary frame, so that rapid assembly of an entire car is realized, and furthermore the bearing capacity of the auxiliary frame is well enhanced; the internal capacity is high, so that the auxiliary frame is also applicable to the hanger bracket provided with a large engine; by virtue of enlarging the engine arrangement space, the comfort brought to passengers by the enlarged space of a carriage is increased.

Description

technical field [0001] The present invention relates to subframes, and more particularly to subframes for independent suspensions. Background technique [0002] At present, the general direction of the layout of the suspension system of a traditional van is as follows: suspension supports, elastic elements, and damping elements are directly connected to the frame, or indirectly connected to the frame through the front beam and various mounting brackets. Therefore, it is usually necessary to configure multiple assembly parts for the corresponding suspension, such as: the front beam assembly, the front support installation and fixing components, and the requirements for the frame itself are relatively high, such as the body needs to have better rigidity to ensure the suspension To achieve good shock absorption and buffering, the body needs to be equipped with 4 or more mounting points, which weakens the deflection of the body. Driven by the professional modularization of toda...

[0002] At present, the general direction of the layout of the suspension system of a traditional van is as follows: suspension supports, elastic elements, and damping elements are directly connected to the frame, or indirectly connected to the frame through the front beam and various mounting brackets. Therefore, it is usually necessary to configure multiple assembly parts for the corresponding suspension, such as: front beam assembly, front support installation and fixing components, and the requirements for the frame itself are relatively high, such as the body needs to have better rigidity to ensure the suspension To achieve good shock absorption and buffering, the body needs to be equipped with 4 or more installation points, which weakens the deflection of the body

Driven by the professional modularization of today's automobile manufacturing, the inadequacy of the traditional suspension and frame connection is more obvious
