Embodiment Construction

[0013] A sub-frame of a passenger car, which has a water tank support beam 10 placed horizontally from front to back along the front and rear direction of the vehicle. The front beam 30, left and right longitudinal beams 40, 50 and rear beam 60 are welded to form a roughly square frame. 10 and the front beam 30 are symmetrically arranged with left and right transition beams 20, including the front side area I where the left and right transition beams 20 are located, and the rear side of the left and right transition beams 20 to the rear beam 60. The area II between the front side and near the rear beam 60 is an energy-absorbing deformation area.

[0014] The compressive and / or flexural strengths of the left and right transition beams 20 in the area I are smaller than the compressive and / or flexural strengths of the left and right longitudinal beams 40, 50 in the area II.

[0015] In order to realize the design in which the compressive and / or flexural strength of the above-ment...

Abstract

The invention provides a subframe of a passenger car. The key structure is that a transverse support beam of a water tank is positioned along the front and back direction from the front side to the back side, a front horizontal beam, a left and right vertical beams and a back horizontal beam are welded to form an approximate square frame, and a left transition beam and a right transition beam are positioned between the support beam of the water tank and the front horizontal beam in symmetry. A front side area I containing the left transition beam and the right transition beam and an area II located from the back side of the left transition beam and the right transition beam to the front side of the back horizontal beam and near the back horizontal beam are energy absorption deformation area. The invention has the advantages of absorbing more energy by the subframe during the collision of the entire passenger car, the deformation in the passenger area as small as possible and protecting the safety of passengers.

Description

technical field [0001] The invention relates to a structural design of an auxiliary frame of a passenger car. Background technique [0002] In the prior art, the function of a subframe of a passenger car in the whole vehicle is generally considered to be used to connect and install parts, powertrain, etc., to play a supporting role, and in a certain sense, to improve the rigidity of the car body, However, the role played by the subframe in the collision of the whole vehicle has not attracted enough attention. Contents of the invention [0003] The purpose of the present invention is to provide a subframe of a passenger car, which can absorb more energy during a collision of the whole vehicle and minimize deformation in the passenger area to protect the safety of passengers. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: a passenger car subframe, the key lies in: along the front and rear direction of the vehic...
