Technical Field

[0001] This utility model relates to the field of fixed mounting mounts for automobile engines or transmissions, and specifically to a combined rubber spring mounting assembly. Background Technology

[0002] Composite rubber spring mounts are vibration damping and buffer assemblies that bear the weight of automotive engines, transmissions, and mechanical equipment while also possessing strong shock resistance. Current rubber spring mounts for engines, transmissions, and mechanical equipment, under harsh operating conditions, must withstand significant torque forces and possess strong vibration filtering capabilities, making them prone to damage and thus considered vulnerable components in extreme operating environments. Utility Model Content

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: a combined rubber spring suspension assembly, comprising an upper steel plate and a lower steel plate, wherein a rubber spring is provided between the upper steel plate and the lower steel plate, a sleeve is fixedly connected to the bottom of the upper steel plate, the rubber spring is sleeved on the sleeve, a through hole is provided in the center of the lower steel plate, the sleeve passes through the through hole, and an anti-detachment steel plate is provided at the bottom of the sleeve.

[0005] As a further embodiment of this utility model: a number of screws are welded to the top of the upper steel plate and the bottom of the lower steel plate, and the screws are evenly arranged on the top of the upper steel plate and the bottom of the lower steel plate.

[0006] As a further embodiment of this utility model: the top of the rubber spring is bonded to the bottom of the upper steel plate, and the bottom is bonded to the top of the lower steel plate.

[0007] As a further embodiment of this utility model: the diameter of the anti-detachment steel plate is larger than the diameter of the through hole opened in the lower steel plate, and the anti-detachment steel plate is connected to the sleeve by bolts.

[0008] As a further embodiment of this utility model: the bottom of the rubber spring is provided with a protrusion, the protrusion passes through the through hole in the center of the lower steel plate, and the top of the protrusion is in contact with the bottom of the lower steel plate.

[0009] As a further improvement of this utility model, the bottom of the protrusion is provided with a groove.

[0010] As a further embodiment of this utility model: the groove is an annular groove centered on the sleeve axis, and the depth of the groove extends to near the top of the rubber spring.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. By setting an anti-detachment steel plate, this utility model can not only achieve the shock absorption function of rubber springs, but also prevent rubber detachment accidents caused by overload. It solves the major accident losses caused by the detachment of rubber spring suspensions in existing vehicles and mechanical equipment due to the lack of anti-detachment design, such as engine block tearing, transmission housing tearing, mechanical equipment housing bracket tearing, etc.

[0013] 2. This utility model has a compact structural design, providing a new solution for the arrangement of vehicles or mechanical equipment and other related components. It solves the long-standing technical problem of unreasonable engine mounting design causing major accidents to the engine block in wheeled vehicles in my country, and solves the technical problem of requiring both super strong shock absorption effect and the ability to avoid tearing the engine block under high torque and high load conditions, while also achieving smooth engine power output.

[0014] 3. This utility model improves the driving comfort and handling of wheeled vehicles, especially heavy wheeled equipment, under extreme off-road conditions; reduces the weight of wheeled vehicles of the same load capacity by 1% to 1.5%, effectively reducing vehicle energy consumption; and also improves the service life of vehicles with the same output torque and load capacity, making it more suitable for high-speed, high-mobility military vehicles and heavy equipment under extreme conditions.

[0015] 4. This utility model reduces the production cost of rubber spring suspension, and has a lower failure rate and a longer maintenance cycle. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] refer to Figures 1 to 3 A combined rubber spring suspension assembly includes an upper steel plate 1 and a lower steel plate 2. A rubber spring 3 is provided between the upper steel plate 1 and the lower steel plate 2. A sleeve 4 is fixedly connected to the bottom of the upper steel plate 1. The rubber spring 3 is sleeved on the sleeve 4. A through hole 5 is opened in the center of the lower steel plate 2. The sleeve 4 passes through the through hole 5. An anti-detachment steel plate 6 is provided at the bottom of the sleeve 4.

[0022] Several screws 7 are welded to the top of the upper steel plate 1 and the bottom of the lower steel plate 2. The screws 7 are evenly arranged on the top of the upper steel plate 1 and the bottom of the lower steel plate 2.

[0023] The top of the rubber spring 3 is bonded to the bottom of the upper steel plate 1, and the bottom is bonded to the top of the lower steel plate 2.

[0024] The diameter of the anti-detachment steel plate 6 is larger than the diameter of the through hole 5 opened in the lower steel plate 2, and the anti-detachment steel plate 6 is connected to the sleeve 4 by bolts 8.

[0025] The bottom of the rubber spring 3 is provided with a protrusion 9, which passes through the through hole 5 in the center of the lower steel plate 2, and the top of the protrusion 9 is in contact with the bottom of the lower steel plate 2.

[0026] The bottom of the protrusion 9 has a groove 10.

[0027] The groove 10 is an annular groove centered on the axis of the sleeve 4, and the depth of the groove 10 extends to near the top of the rubber spring 3.

[0028] In practical application, the engine, transmission, or other mechanical equipment are connected to the screws 7 on the upper steel plate 1, and the vehicle frame or the base of the mechanical equipment is fixed to the screws 7 on the lower steel plate 2. The anti-detachment steel plate 6 is fixed to the sleeve 4 on the upper steel plate 1 by bolts 8. The weight of the engine, transmission, and mechanical equipment presses on the upper steel plate 1. All impact loads during the operation of the engine, transmission, and mechanical equipment and during vehicle bumps are filtered out by the rubber spring 3 filled between the upper steel plate 1 and the lower steel plate 2. If the rubber spring 3 detaches due to overload, the anti-detachment steel plate 6 will press against the lower steel plate 2 to prevent safety accidents caused by detachment. The combined rubber spring suspension assembly can amplify the tension of the rubber spring to 2.5 to 4 times the design theoretical tension.
