Embodiment Construction

[0016] Below in conjunction with accompanying drawing and embodiment the present invention will be further elaborated:

[0017] Such as Figure 1 to Figure 4 The installation structure of the subframe and the vehicle body shown includes the subframe and the side beam inner liner 4 of the engine compartment. The subframe includes the upper and lower sheet metal parts 2, 3 and the upper and lower sheet metal parts. Between the support 1, the support 1 is a hollow cylinder with a T-shaped section, a boss 11 is provided on the big end of the support, and a boss 11 is arranged on the top of the boss. There are knurling patterns 12, the knurling patterns 12 are corrugated radially outward along the center line of the support member, the inner wall of the upper sheet metal part 2 is assembled and bonded to the end surface of the big end of the support member, and the top surface of the boss 11 is as high as The outer wall of the upper sheet metal part is attached to the installation...

Abstract

The invention discloses an installation structure of a sub-frame and a vehicle body, comprising a sub-frame and a vehicle body, the sub-frame includes upper and lower sheet metal parts and a supporting part arranged between the upper and lower sheet metal parts, the The support member is a hollow cylinder, and a boss is provided on the end surface of one end of the support member. The inner wall of the upper sheet metal part is assembled and bonded to the end surface of the support member, and the top surface of the boss is higher than the upper surface. The outer wall of the sheet metal part is attached to the installation surface of the vehicle body. The invention greatly reduces the contact area of ​​the assembling part and increases the contact pressure, thereby being beneficial to control the shape and position tolerance of the contact surface, and making the assembly of the sub-frame and the vehicle body more firm.

Description

technical field [0001] The invention relates to an automobile body structure, in particular to a mounting structure for a sub-frame and a vehicle body. Background technique [0002] In the design of the vehicle suspension system, the installation structure of the sub-frame and the body is directly related to the stability of the suspension. Generally, the sub-frame and the body of a car adopt a four-point connection. Such as Figure 5 , Figure 6 As shown, the existing automobile subframe includes upper and lower sheet metal parts 2, 3, and a hollow support member 5 is provided between the upper and lower sheet metal parts, and the support member is located in the through hole of the upper and lower sheet metal parts. At the position, the upper and lower sheet metal parts are pressed against the two ends of the supporting part to support the upper and lower sheet metal parts. In the assembly of the sub-frame and the vehicle body, the outer wall of the upper sheet metal par...
