Abstract

The invention relates to a pocket beam support for a commercial vehicle independent suspension. The support comprises a front bracket assembly, a rear bracket assembly and a middle bracket located between the front bracket assembly and the rear bracket assembly, wherein the front bracket support and the rear bracket support are each of a U-shaped structure, a rear middle bracket in the rear bracket assembly comprises a rear middle bottom plate, a rear middle inclined plate, a left bottom protruding block and a right bottom protruding block, the front side and the right side of the rear middlebottom plate are connected with a front bending flange and a rear bending flange which extend upwards respectively, the middle of the front bending flange is connected with the bottom of the rear middle inclined plate embedded in the front bending flange, the back of the rear middle inclined plate is vertically connected to the top surface of the rear middle bottom plate through a rear wedge plate, the portions, located at the left end and the right end, of the bottom surface of the rear middle bottom plate are connected with the left bottom protruding block and the right bottom protruding block respectively, stabilizer bar mounting holes are formed in the left bottom protruding block and the right bottom protruding block, and steering engine mounting holes are formed in the rear middle inclined plate. Accordingly, the functionality is high, the stiffness is good, the weight is low, butt welding and connection are facilitated, the manufacturing cost is low, and the occupied space is small.

Description

technical field [0001] The invention relates to a commercial vehicle chassis suspension system, in particular to a pocket beam bracket for an independent suspension suspension of a commercial vehicle, which is particularly suitable for increasing the functionality and rigidity of the pocket beam bracket. Background technique [0002] Existing medium and heavy commercial vehicles use a leaf spring type non-independent suspension, which is matched with an integral bridge, which leads to problems such as heavy weight of the suspension assembly, large unsprung mass, high stiffness, and poor comfort. [0003] The publication number is CN106394154A, and the invention patent application published on February 15, 2017 discloses a commercial vehicle single front axle structure with independent suspension, including symmetrically arranged left independent suspension and right independent suspension. The left independent suspension is connected with the right independent suspension thr...
