Embodiment Construction

[0027] Below in conjunction with accompanying drawing and specific embodiment the present invention will be described in further detail:

[0028] Such as figure 2 and image 3 As shown, a front axle welding assembly includes the front axle welding structure including a left suspension bracket 20, a right suspension bracket 21, a steering gear bracket 1, a beam 4, a left suspension bracket 20, a right suspension bracket Bracket 21 and steering gear bracket 1 are all integrated on the crossbeam 4 by stamping and welding, and the left suspension bracket 20 and the right suspension bracket 21 are installed on the two ends of the crossbeam 4, and there is no gap before the crossbeam. Therefore, in the traditional sub-frame structure, because the left suspension bracket 20 and the right suspension bracket 21 are partly located outside the cross beam 4, the left suspension bracket 20 and the right suspension bracket 21 have an additional bending moment, resulting in left suspension...

Abstract

The invention belongs to an automobile front axle component, and particularly relates to a front axle welding part structure. The front axle welding part structure comprises suspension supports, a steering gear support and a cross beam; the suspension supports and a steering gear are arranged on the cross beam; the suspension supports are provided with a left suspension support and a right suspension support; the suspension supports are located at the two ends of the cross beam; the suspension supports are in fastening connection with the cross beam; no gap exists between the suspension supports and the cross beam; the steering gear support is located on the side faces of the opposite inner ends of the two suspension supports; the steering gear support is connected with the cross beam and the suspension supports. The extra torque negative effects of suspension loads of an engine and loads of a control arm are avoided to the greatest extent; and the component is quite favorable to improving rigidity, the mode and the reliability of the whole front axle welding part structure.

Description

technical field [0001] The invention belongs to an automobile front axle assembly, in particular to an automobile front axle welding piece structure. Background technique [0002] Install some or all of the components of the suspension system, steering system, and power transmission system on the frame, and connect the frame with the body. Such a frame is called a subframe and is used in front of the engine. Front-wheel drive models. The suspension components are directly connected to the sub-frame, and the same vibration is buffered by the sub-frame, and then transmitted to the body, the vibration will be greatly reduced, thereby improving the comfort of the vehicle. In addition, since the sub-frame is stronger than the body, the connection of the sub-frame greatly improves the stiffness of the suspension connection, which not only improves comfort, but also has unique advantages in terms of improving chassis strength and handling. However, the negative impact of the addi...
