Frame for unmanned drive-by-wire chassis

Abstract

The invention belongs to the technical field of unmanned drive-by-wire chassis, and discloses a frame for an unmanned drive-by-wire chassis, which comprises a carriage mounting surface (1), a drive-by-wire brake system mounting support (2), a rear anti-collision buffer mechanism mounting surface (3), a front anti-collision buffer mechanism mounting surface (6), a rear suspension mounting support group (4), a front suspension mounting support group (7), a battery mounting box (5); and an electric device mounting box (8). The structure of the unmanned drive-by-wire chassis is optimized, and the overall reliability of the frame is improved. The brake-by-wire system mounting support (2) is mainly formed by cutting and bending a plate and is welded on a frame rod system to form a three-dimensional stress structure. Meanwhile, the stress length of a fixed screw rod is increased, and the alternating load bearing capacity of the screw rod after being tightened is improved, so that the mounting reliability of the brake-by-wire system is improved.

Description

technical field [0001] The invention belongs to the technical field of unmanned drive-by-wire chassis, and in particular relates to a vehicle frame for an unmanned drive-by-wire chassis. Background technique [0002] At present, the production and processing of the frame of the small unmanned drive-by-wire chassis is still in the stage of small batches, and most of the frames are cut and welded by standard profiles. The structural design of the frame and the welding process play a vital role in the reliability and durability of the frame. The mainstream brake-by-wire system mounting bracket is cut and welded by flat steel plates. The brake-by-wire system is fixed on a flat plate through screws, and the flat plate is welded to the frame rod system. The stress is large, and at the same time, due to the limited thickness of the plate, the force length of the fixed screw is limited, which reduces the ability of the screw to withstand alternating loads after being tightened. ...

AI Technical Summary

Problems solved by technology

The mainstream brake-by-wire system mounting bracket is cut and welded by flat steel plates. The brake-by-wire system is fixed on a flat plate through screws, and the flat plate is welded to the frame rod system. The stress is large, and at the same time, due to the limited thickness of the plate, the force length of the fixed screw is limited, which reduces the ability of the screw to withstand alternating loads after being tightened

[0003] At present, the installation method of the front and rear suspensions is mainly by welding the suspension connecting rod lugs on the frame rod system. Since the connection points of the suspension and the frame are subjected to large alternating loads for a long time, its influence on the connecting rod lugs Welding reliability puts forward higher requirements. Due to the thermal stress in welding, the connection strength of welding parts will be low. In order to improve the reliability of the frame and ensure the safety performance of the vehicle, it is necessary to optimize the connection method of the suspension link and the frame.
