The invention discloses a gearbox bracket assembly of a half-load passenger car, and relates to the technical field of automobile parts. The gearbox bracket assembly is of a sectional structure and isof a U-shaped structure as a whole, the cross sections of first connecting cross beams and a second connecting cross beam are of an n-shaped structure, the inner surfaces of the first connecting cross beams are matched with the outer surface of the second connecting cross beam, and the first connecting cross beams are arranged at the two ends of the second connecting cross beam; and a round holeis formed in the surface of each first connecting cross beam, long round holes are correspondingly formed in the installation positions between the second connecting cross beam and the first connecting cross beams, and first long bolts and short bolts are arranged on the surface of the first connecting cross beams and the surface of the second connecting cross beam correspondingly. The problems that the gearbox brackets of most traditional half-load passenger car are of integrated steel plate punch forming structures or formed by welding multiple sections of connecting plates into a whole, thestrength and the dynamic stiffness are insufficient, and gaps are not prone to adjustment when manufacturing errors and assembling errors exist are solved.
本发明公开了一种半承载客车变速箱托架总成,本发明涉及汽车零件技术领域。通过变速箱托架总成为分段式结构,并且整体为“U”型结构,第一连接横梁和第二连接横梁的横向截面段为“几”型结构,并且第一连接横梁的内表面与第二连接横梁的外表面间相适配,第一连接横梁设置在第二连接横梁的两端,第一连接横梁的表面上开设有圆孔,第二连接横梁与第一连接横梁之间安装位置处对应开设有长圆孔,第一连接横梁和第二连接横梁的表面上均设置有第一长螺栓和短螺栓,解决了传统半承载客车变速箱托架多为一体式钢板冲压成型结构或多段连接板焊接成一体,但强度及动刚度不足,制造误差及装配误差时,不容易调整间隙的问题。
