Description

Technical Field

[0001] The utility model relates to the field of automotive parts, and particularly to a detachable top mount. Background Art

[0002] An automotive top mount is a shock-absorbing and buffering component that connects the vehicle shock absorber to the body. It relieves the impact of the shock absorber's vibration on the body, protects the shock absorber, and extends its service life. The top mount mainly consists of a mounting bracket housing and a rubber buffer part. The common failure is the aging failure of the rubber buffer part (core body). At this time, the metal part (housing) often has not failed yet, but the top mount needs to be replaced, resulting in a relatively high replacement cost. Summary of the Utility Model

[0007] a pressure ring. The outer circumferential wall of the pressure ring is provided with a second thread that matches the first thread. The pressure ring is arranged on the axial outer side of the core body to press the core body tightly.

[0008] A hexagonal boss is provided on a part of the pressure ring that extends out of the second installation cavity.

[0009] The housing includes a mounting plate. The mounting plate is provided with mounting holes for screw installation. It further includes a rubber pad. The rubber pad is arranged on the outer end face of the mounting plate and is coaxially arranged with the mounting holes.

[0010] A plurality of sinking grooves are provided on the outer end face of the mounting plate.

[0011] The core body includes a base. An inner skeleton made of a metal material is arranged in the base.

[0012] The inner skeleton is made of 20 steel.

[0013] A boss is provided on the mounting plate. The second installation cavity is axially arranged on the boss. The connection between the boss and the mounting plate is in an arc transition.

[0014] The beneficial effects of the present utility model are as follows: The present utility model provides a detachable top mount. When the core body fails, only the core body part needs to be replaced, reducing the replacement cost of the top mount failure and improving the economy. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 2 It is a schematic view of an embodiment of the present utility model. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The following further describes the present utility model with reference to the drawings: As shown in the figure, a detachable top mount includes a housing 1. The housing is axially provided with a first installation cavity 2. A core body 3 is arranged in the first installation cavity. It further includes a second installation cavity 4. The first installation cavity is communicated with the second installation cavity. The inner wall of the second installation cavity is provided with a first thread; a pressing ring 5. The outer circumferential wall of the pressing ring is provided with a second thread that matches the first thread. The pressing ring is arranged on the axial outer side of the core body to press the core body. When replacement is needed, the pressing ring is removed, and the core body can be replaced. When in use, the pressing ring is installed, and the core body is tightly fixed in the first installation cavity, which is convenient for disassembly and assembly.

[0018] In this embodiment, as shown in the figure, a hexagonal boss 51 is provided on a part of the pressing ring extending out of the second installation cavity. Disassembly and assembly can be conveniently achieved through a wrench.

[0019] In this embodiment, as shown in the figure, the housing includes an installation plate 11. The installation plate is provided with installation holes 111 for screw installation. It further includes a rubber pad 112. The rubber pad is arranged on the outer end face of the installation plate. The rubber pad is coaxially arranged with the installation holes.

[0020] In this embodiment, as shown in the figure, a plurality of sinking grooves 113 are provided on the outer end face of the installation plate. The contact area between the top mount and the vehicle body is reduced, reducing the vibration transmission of the top mount to the vehicle body, improving the driving smoothness and comfort of the vehicle. At the same time, the weight of the housing is reduced, materials are saved, the lightweight design improves fuel economy, and the design cost is reduced.

[0021] In this embodiment, as shown in the figure, the core body includes a base 31. An inner skeleton 32 made of a metal material is arranged in the base. The inner skeleton is wrapped outside the base. The base is made of materials such as rubber and is installed in the first installation cavity, improving the strength, reliability of the top mount, and safety of the vehicle. The static stiffness of the product is improved, and thus the handling performance of the vehicle is optimized.

[0022] In this embodiment, as shown in the figure, the inner skeleton is made of 20 steel.

[0023] In this embodiment, as shown in the figure, a boss 14 is provided on the mounting disk. The second mounting cavity is axially provided in the boss, and the connection between the boss and the mounting disk is in an arc transition. The fillet design is added, which can reduce the risk of cracking of the cast aluminum parts caused by stress concentration.
