Description

Left side suspension support

Technical Field

The utility model relates to an automobile engine part technical field specifically is a left side suspension support.

Background

With the rapid development of automobile technology, people have higher and higher performance requirements on various aspects of automobiles, the vibration and noise of the automobiles, which are one of the performance indexes of the automobiles, are more and more prominent, the mass consumption is gradually rationalized, and the low oil consumption and the good comfort are required for the purchase concept of the automobiles. In order to adapt to the changing trend of the market, the light weight which can meet the requirements of vehicle shock absorption, noise reduction and strength and simultaneously reduce the self weight of the vehicle is the current development direction.

The automobile engine generally adopts the suspension support to install in the automobile body, because the automobile body inner space is less, and the vibrations that the vehicle travel in-process produced are great, require that the suspension support has better intensity and rigidity. The engine left suspension is positioned on the left side of the power assembly, and plays a role in connecting and fixing the power assembly and isolating vibration transmission between the power assembly and a vehicle body. The engine left side suspension assembly generally includes connecting support arm, left side suspension rubber main spring subassembly and support, and current engine left side suspension support adopts stamping forming's meal gold spare welding to form usually, and stamping forming's meal gold spare has heavy, and the welding is troublesome, and the precision is not good to be guaranteed. When the left suspension bracket is made of other materials such as plastics, the strength of the bushing shell is difficult to ensure, and the connection reliability with the rubber main spring assembly is also a problem to be considered.

Disclosure of Invention

In order to solve current left suspension support weight heavy, the trouble problem of welding, the utility model provides a left suspension support, it is when reducing weight and simplifying technology, ensures product strength and assembly reliability.

The technical scheme is as follows: the utility model provides a left side suspension support, its includes the support body, its characterized in that, support body outer wall is provided with the connecting piece, the support body with the PA66+ GF50 working of plastics of connecting piece for integrated into one piece, be provided with metal insert on the connecting piece, the draw-in groove has been seted up on the support body inner wall.

The bracket is further characterized in that the inner wall of the bracket body is also provided with a guide groove;

ribs are arranged on the outer wall of the bottom of the bracket body, and the thickness of each rib is less than 4 mm;

the bracket body is of a circular structure;

a spherical convex point is arranged at the center of the outer wall of the bottom of the bracket body;

the metal inserts are aluminum inserts and 1215 steel inserts.

Adopt the utility model discloses afterwards, change into PA66+ GF50 working of plastics with the support body, the effectual weight that has reduced and intensity obtains guaranteeing to seted up the draw-in groove on the inner wall, can guarantee to be connected more reliably with rubber main spring subassembly, metal insert on the connecting piece is used for being connected left suspension support and other parts.

Detailed Description

Referring to fig. 1 to 3, a left suspension bracket comprises a bracket body, a connecting piece 2 is arranged on the outer wall of the bracket body 1, the bracket body 1 and the connecting piece are integrally injection-molded PA66+ GF50 plastic pieces, an aluminum insert 3 and a 1215 steel insert 4 are arranged on the connecting piece 2, in order to meet a pressure change test, an aluminum material is selected to be AL-6061-T6, two clamping grooves 5 and a guide groove 6 are arranged on the inner wall of the bracket body 1, when a rubber main spring assembly is assembled with the bracket body 1, interference press fitting is adopted, the requirement of pull-out force is met, and meanwhile, the clamping grooves 5, the guide groove 6 are matched with a clamping block 7 and a guide rail bar 8 of a bushing shell, the pull-out force is further improved, so that the phenomenon of pull-out cannot occur after the assembly of.

Be provided with rib 9 on the outer wall of support body 1 bottom, rib 9 thickness is less than 4mm, under the condition that satisfies intensity, also convenient in moulding plastics.

The support body 1 is of a circular structure, and compared with an existing common square structure, the support is small in occupied space, even in stress and more stable and reliable in structure.

The spherical salient point 10 is arranged at the center of the outer wall of the bottom of the bracket body 1, the thickness of the salient point is thicker than the thickness of the salient point for improving the overall strength, but the glue injection port injects glue from the point, so that the structural defects are avoided, and the process is met.
