Description

Technical Field

[0001] The utility model relates to the technical field of automobile suspension damping shock absorbers, in particular to an infinite position plate support suspension assembly. Background Art

[0002] Conventional automobile suspension upper support suspensions all have a limit plate structure at their upper ends, and the limit plate is usually assembled on the metal bracket of the upper support suspension by riveting and curling. Due to the popularity of electric vehicles, people have higher and higher requirements for lightweight parts and NVH performance. Therefore, a large amount of aluminum and engineering plastics are used in vehicles to achieve lightweight, especially the upper support suspension bracket, which often adopts a high-pressure cast aluminum structure to replace the original commonly used sheet metal stamping bracket structure. In addition, the compactness of the cast aluminum bracket structure also improves the modal of the part itself and avoids the risk of resonance with other parts. However, for high-pressure cast aluminum brackets, there is a weakness of low material elongation, that is, the part is brittle.

[0003] When the limit plate is assembled on the high-pressure cast aluminum bracket by riveting and curling, various process problems often occur, such as cracking of the curling end, looseness after curling, abnormal noise caused by loosening and collision, low push-out force of the limit plate, etc. For this reason, people have to use high-pressure cast aluminum material with better elongation and perform certain artificial aging treatment, but this further increases the cost of parts, and the problem cannot be completely improved, and certain undesirable phenomena still exist.

[0004] To this end, we propose an infinite plate support suspension assembly. Utility Model Content

[0005] In view of the shortcomings of the above-mentioned existing production technology, the applicant provides a support suspension assembly on an unlimited plate, thereby eliminating the rotary riveting and curling process by eliminating the limit plate. At the same time, the bracket can be made of ordinary high-pressure cast aluminum, and there is no need to consider problems such as high elongation materials and artificial aging, and the cost of parts is further reduced.

[0006] The technical solution adopted by the utility model is as follows:

[0007] An infinite plate support suspension assembly, comprising:

[0008] Bracket;

[0009] Vibration-isolating rubber bushings, interference-fitted into the bracket;

[0010] A sealing ring is arranged at the upper end of the vibration isolation rubber bushing to seal and prevent dust;

[0011] Among them, the vibration isolation rubber bushing includes vibration isolation rubber, and multiple main spring bumps and limit bumps are arranged on the upper and lower ends of the vibration isolation rubber; the height of the main spring bumps is greater than the height of the limit bumps. After assembly, the main spring bumps at both ends of the vibration isolation rubber fit with the vehicle body. When the load is large, the vibration isolation rubber bushing moves upward, so that the limit bumps directly collide with the vehicle body for limiting.

[0012] It is further characterized by:

[0013] Both ends of the top of the bracket are provided with positioning pins for positioning with the vehicle body to prevent the bracket from rotating during assembly.

[0014] The material of the bracket is conventional high-pressure cast aluminum.

[0015] The vibration-isolating rubber bushing comprises a plastic outer tube and an inner core, and the plastic outer tube and the inner core are vulcanized into one by the vibration-isolating rubber.

[0016] The inner core comprises an inner core gasket and an inner core coating plastic.

[0017] The inner core gasket and the inner core coating plastic are integrated by injection molding.

[0018] Four main spring bumpers and four limit bumpers are provided on the upper end of the vibration isolation rubber.

[0019] The main spring bumpers and the limiting bumpers are arranged together in pairs, and both sides of the two main spring bumpers are both limited bumpers arranged in pairs.

[0020] The upper and lower ends of the vibration isolation rubber have the same structure.

[0021] The beneficial effects of the utility model are as follows:

[0022] The utility model has a compact and reasonable structure and is easy to operate. After installation, the four main spring bumpers at the upper end of the vibration isolation rubber directly fit with the vehicle body, the four main spring bumpers at the lower end of the vibration isolation rubber directly fit with the bracket, and the sealing ring at the upper end of the vibration isolation rubber bushing directly fits with the vehicle body. Under a large load, the inner core is driven to move upward, and then the vibration isolation rubber is driven to move upward, so that the four limit bumpers of the vibration isolation rubber directly collide with the vehicle body, thereby realizing the limit function. The number of assembly parts is reduced, the weight is reduced, and the process steps are reduced. The product assembly is simple, safe and reliable. The rotary riveting and curling process is eliminated by eliminating the limit plate. At the same time, the bracket can be made of ordinary high-pressure cast aluminum, and there is no need to consider high-elongation materials and artificial aging issues, and the cost of parts is further reduced.

[0023] At the same time, the utility model also has the following advantages:

[0024] (1) Both ends of the top of the bracket are provided with positioning pins, which are used for positioning. When assembling with the vehicle body, the positioning pins are inserted into the positioning holes on the vehicle body, and the bracket will not rotate during the process of driving the bolts into the mounting holes.

[0025] (2) A sealing ring is provided at the upper end of the vibration isolation rubber bushing to prevent dust. The dustproof sealing ring is in direct contact with the vehicle body, which not only retains the dustproof function but also eliminates the dust cover, thereby reducing the number of assembly parts, reducing weight, and reducing process steps.

[0031] The specific implementation of the present utility model is described below in conjunction with the accompanying drawings.

[0032] like Figure 1-Figure 4 As shown, an infinite plate support suspension assembly includes a bracket 1, a vibration isolation rubber bushing 2 and a sealing ring 3, wherein the vibration isolation rubber bushing 2 is arranged in the bracket 1.

[0033] The material of the bracket 1 is conventional high-pressure cast aluminum, and it is connected to the vehicle body assembly. Both ends of the top of the bracket 1 are provided with positioning pins 101, and positioning is performed by the positioning pins 101. When assembling with the vehicle body, the positioning pins 101 are inserted into the positioning holes on the vehicle body, and the bracket 1 will not rotate when the bolts are driven into the mounting holes.

[0034] The vibration isolation rubber bushing 2 is interference fitted with the bracket 1, and vibration reduction is performed through the vibration isolation rubber bushing 2. The vibration isolation rubber bushing 2 includes a plastic outer tube 201, an inner core gasket 202, an inner core coated plastic 203 and a vibration isolation rubber 204. The vibration isolation rubber 204 is arranged in the plastic outer tube 201, the inner core coated plastic 203 is arranged in the vibration isolation rubber 204, and the inner core gasket 202 is arranged in the inner core coated plastic 203. The inner core gasket 202 and the inner core coated plastic 203 constitute the inner core and are integrated by injection molding. The plastic outer tube 201 and the inner core are vulcanized into one by the vibration isolation rubber 204.

[0035] A sealing ring 3 is provided at the upper end of the vibration isolation rubber bushing 2 to prevent dust.

[0036] The upper and lower ends of the vibration isolation rubber 204 are both provided with main spring bumpers 2041 and limit bumpers 2042. The height of the main spring bumpers 2041 is greater than the height of the limit bumpers 2042. The upper and lower ends of the vibration isolation rubber 204 have the same structure. There are four main spring bumpers 2041 and limit bumpers 2042 at the upper end of the vibration isolation rubber 204. The main spring bumpers 2041 and limit bumpers 2042 are both arranged together in pairs, and both sides of the two main spring bumpers 2041 are both provided with limit bumpers 2042 arranged in pairs.

Under a large load condition, the core moves upward, thereby driving the vibration isolation rubber 204 to move upward, so that the four limit bumpers 2042 of the vibration isolation rubber 204 directly collide with the vehicle body, thereby realizing the limit function.

[0037] In specific use, when assembling with the vehicle body, the positioning pin 101 is inserted into the positioning hole on the vehicle body.

Under a large load, the inner core moves upward, thereby driving the vibration isolation rubber 204 to move upward, so that the four limit bumpers 2042 of the vibration isolation rubber 204 directly collide with the vehicle body, thereby realizing the limit function. The number of assembly parts is reduced, the weight is reduced, the process steps are reduced, and the product assembly is simple, safe and reliable. The rotary riveting and curling process is eliminated by eliminating the limit plate. At the same time, the bracket 1 can be made of ordinary high-pressure cast aluminum, and there is no need to consider high-elongation materials and artificial aging issues, and the cost of parts is further reduced.
