Embodiment 1

[0032] This embodiment provides a positioning installation structure for the front sub-frame of an automobile, which includes: a bushing arranged on the installation surface of the front sub-frame, a fixing nut arranged in the mounting seat of the vehicle body, the mounting seat body, and a mounting reinforcement plate, and fixing bolts.

[0033] Wherein, a through hole is provided in the casing, and the diameter of the through hole is slightly larger than the threaded outer diameter of the fixing bolt, so that the fixing bolt can pass through the through hole; the fixing nut, the installation reinforcement plate and the installation The seat body is fixedly connected in turn, and the fixing nut adopts an inverted concave structure, so that a cavity is formed at the bottom of the fixing nut connected with the installation reinforcement plate, and the inner thread of the fixing nut matches the outer thread of the fixing bolt , the mounting reinforcement plate is provided with a...

Embodiment 2

[0055] This embodiment provides a positioning installation structure for the front sub-frame of an automobile, which includes a sub-positioning installation structure disposed on the front sub-frame, a sub-positioning installation structure disposed on the vehicle body, and fixing bolts.

[0056] Such as figure 1 As shown, the sub-positioning installation structure arranged on the front subframe specifically includes: a cylindrical sleeve 2 arranged on the flange mounting surface 5 of the front subframe and a rubber sleeve sleeved on the cylindrical sleeve 2 Bushing 4. The top shape of the cylindrical sleeve 2 is a truncated cone 1 to play a guiding role; the cylindrical sleeve 2 is provided with a through hole 3, and the cylindrical sleeve 2 is the same as the through hole 3 Shaft setting, the diameter of the through hole 3 is slightly larger than the outer diameter of the thread of the fixing bolt, the through hole 3 not only penetrates the cylindrical sleeve 2, but also ne...

Abstract

The invention provides a locating and mounting structure of an automobile front auxiliary frame. The locating and mounting structure comprises a casing pipe, a fixed nut, a mounting base body, a mounting reinforcing plate and a fixed bolt, and the casing pipe is arranged on a mounting face of the front auxiliary frame. The fixed nut, the mounting base body, the mounting reinforcing plate and the fixed bolt are arranged in a mounting base of an automobile body, a through hole is formed in the casing pipe, and the diameter of the through pipe is slightly larger than the outer diameter of threads of the fixed bolt. The fixed nut, the mounting reinforcing plate and the mounting base body are sequentially and fixedly connected, the fixed nut is in an inverted concave shape so that a cavity can be formed in the bottom of the fixed nut, internal threads of the fixed nut are matched with external threads of the fixed bolt, a locating hole is formed in the mounting reinforcing plate, a locating via hole is formed in the mounting base body, and the top of the casing pipe sequentially penetrates through the locating via hole and the locating hole and enters the cavity. The fixed bolt penetrates through the through hole in the casing pipe and is connected with the fixed nut through threads. Correspondingly, an automobile adopting the locating and mounting structure is provided. The locating and mounting structure can meet the locating need and facilitate control over mounting precision.

Description

technical field [0001] The invention relates to the technical field of automobile assembly, in particular to a positioning installation structure for a front sub-frame of an automobile, and an automobile adopting the positioning installation structure. Background technique [0002] At present, passenger cars generally adopt a sub-frame structure. The subframe can be regarded as the skeleton of the front and rear axles, and is a component of the front and rear axles. The front and rear suspensions can be assembled on the subframe first to form an axle assembly, and then the car assembly is installed on the car together. body. There are four installation connection points between the front sub-frame and the body, which are: left front connection point, right front connection point, left rear connection point and right rear connection point, among which, installation structures are provided at the four connection points (realized by bolts). ), but generally only two connectio...
