Problems solved by technology

It is also considered that it is difficult to uniformly form the wall thickness of the subframe due to core displacement, resulting in a thick part, which hinders the realization of weight reduction of the subframe
Furthermore, it is difficult to uniformly form the thickness of the subframe, which prevents the strength of the subframe from being stabilized over the entire frame.

Abstract

The present invention provides a vehicle subframe capable of uniformly forming the thickness of the subframe. A subframe (15) of a vehicle has a hollow body portion (32) formed by a core unit (200). The auxiliary frame (15) includes: an upper parallel part (52) and a lower rear parallel part (71), which are arranged on the upper part (41) and the lower part (42) of the main body part (32), and are roughly parallel; mouth (56) and upper right row sand mouth (57), they are formed in the upper parallel part (52); (71). The lower left rear sand discharge port (75) is arranged at the position opposite to the left upper sand discharge port (56), and is formed into the same shape as the left upper sand discharge port (56). The lower right rear sand discharge port (76) is arranged at the position opposite to the upper right sand discharge port (57), and is formed into the same shape as the right upper sand discharge port (57).

Description

technical field [0001] The present invention relates to a subframe of a vehicle which is provided under a vehicle body and supports left and right suspensions through left and right end portions. Background technique [0002] In a vehicle, there is known a structure in which a cast subframe is provided on a vehicle frame, and constituent members such as a transmission device are supported on the subframe. The sub-frame is formed hollow by a core placed in a cavity of a casting mold during casting. In addition, in order to remove the core after casting, the subframe has a core outlet (hereinafter referred to as "sand discharge port") formed in the lower part. The weight of the sub-frame is reduced by forming the sub-frame in a hollow shape (for example, refer to Patent Document 1). [0003] prior art literature [0004] patent documents [0005] Patent Document 1: Japanese Patent Laid-Open No. 2009-298402 [0006] Here, in order to form the sand outlet in the lower part ...
