Embodiment 1

[0024] Such as Figure 1-3 As shown: an integrated subframe, including a subframe body 21 and a rear beam 22, the subframe body is composed of a whole tube, the subframe body includes a front beam 4 and a longitudinal arm 1, and the front beam Seamlessly connected with the trailing arm, a first corner 15 is provided at the connection between the front cross member and the trailing arm, a trailing arm transition area 16 is provided in the middle of the trailing arm, and a second corner 17 and a third corner are provided at the end of the trailing arm 18: The width of the cross-section of the middle portion of the tube in the transition zone of the trailing arm on the left and right trailing arms is wider than the height, and the height of the cross-section of the tube from the transition zone of the trailing arm to the end of the trailing arm is greater than the width. The outside of the pipe body at the first corner is welded with a right suspension mounting bracket 5 . The r...

Abstract

The invention relates to the technical field of cars, and discloses an integrated auxiliary frame in order to solve the problems that a current auxiliary frame is complicated in structure, difficult to machine, insufficient in stiffness and poor in stability. The integrated auxiliary frame comprises an auxiliary frame body and a rear transverse beam, the auxiliary frame body is composed of a wholepipe, the auxiliary frame body comprises a front transverse beam and longitudinal arms the front transverse beam and the longitudinal arms are seamlessly connected, first corners are arranged at thepositions where the front transverse beam is connected with the longitudinal arms, longitudinal arm transition areas are arranged in the middles of the longitudinal arms, and second corners and thirdcorner are arranged at the tail ends of the longitudinal arms. The rear transverse beam comprises a rear transverse beam front rod, a rear transverse beam rear rod and a rear suspension installation plate which are connected through welding. The two ends of the rear transverse beam front rod are connected with the second corners on the left and right longitudinal arms respectively, and the two ends of the rear transverse beam rear rod are inserted into longitudinal arm pipes through welding holes between the second corners and the second corners, and connected with the welding holes through welding. The integrated auxiliary frame is simple in structure, high in stability and low in manufacturing cost, and the whole and local rigidity of the auxiliary frame is easily improved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an integrated auxiliary frame. Background technique [0002] The subframe can be regarded as the skeleton of the front and rear axles, and is an integral part of the front and rear axles. The sub-frame is not a complete frame, but a bracket that supports the front and rear axles and suspensions, so that the axles and suspensions pass through it and then connect with the "positive frame", which is customarily called "sub-frame". The function of the sub-frame is to block vibration and noise and reduce its direct entry into the compartment, so it mostly appears on luxury cars and off-road vehicles, and some cars are also equipped with a sub-frame for the engine. In the traditional load-bearing body without subframe, the suspension is directly connected with the steel plate of the body. Therefore, the suspension rocker mechanism of the front and rear axles is all parts, not an ...
