Description

Heavy-duty vehicle engine rear suspension cushion assembly

technical field

The utility model relates to the technical field of automobile manufacturing, in particular to a connection device used between a heavy-duty automobile engine and a vehicle frame.

Background technique

The engine of a heavy-duty vehicle is usually fixed on the frame of the vehicle. Since the engine of a heavy-duty vehicle will produce a large continuous vibration when it is working, this vibration is also transmitted to the frame of the heavy-duty vehicle, causing the entire heavy-duty vehicle to generate vibration. Vibration affects the comfort of the driver and also produces noise pollution to the surrounding environment; in order to reduce the vibration caused by the engine operation, a vibration damping device is usually installed between the engine and the frame to reduce the engine operating time. The vibration of this kind of damping device that is arranged between the heavy-duty vehicle engine and the vehicle frame at present is composed of many parts, and these parts need to consume a lot of time when assembling, and the damping effect is not good.

Contents of the invention

The purpose of the utility model is to provide a heavy-duty vehicle engine rear suspension cushion assembly, which can solve the problems of labor-consuming and time-consuming installation of the existing heavy-duty vehicle engine vibration damping device and poor vibration damping effect.

In order to solve the above problems, the technical solution adopted by the utility model is:

This heavy-duty vehicle engine rear suspension cushion assembly includes a hollow conical outer casing with holes at both ends and an inner skeleton arranged in the cavity of the outer casing, the large end of the outer casing is flanged outwards, The small end is turned inward, the shape of one end of the inner skeleton is a hexahedral hollow cavity, and the other end is a cuboid, and the cuboid of the inner skeleton protrudes from the hole at the small end of the outer shell; in the inner skeleton A main rubber block and a plastic plate are arranged radially between the hollow cavity of the inner frame and the inner cavity of the outer shell; damping blocks and limit blocks are arranged in sequence from right to left in the hollow cavity of the inner skeleton, so that The limiting block abuts against the baffle plate, and the baffle plate is fixed on the big end of the outer casing.

In the above technical solution, a further solution is: the plastic plate and the main rubber block are fixed on the outside of the hexagon of the inner skeleton.

Further: the main rubber block and the damping block are made of rubber material.

Further: the main rubber block is composed of a "eight"-shaped surface, a reverse "eight"-shaped surface and a connecting part, and the shape of its inner cavity matches the outer hexahedron of the inner skeleton.

Further: the plastic plate is arranged on the outside of the "eight"-shaped surface and the inverted "eight"-shaped surface of the main rubber block.

Due to the adoption of the above technical solution, the utility model has the following beneficial effects compared with the prior art:

1. The utility model has reliable structure, convenient assembly, large adjustment range of overall assembly stiffness, and good vibration reduction effect;

2. The utility model is integral and can be pre-assembled off the assembly line, saving on-line assembly time.

detailed description

Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail: this heavy-duty vehicle engine rear suspension cushion assembly as shown in Fig. 1, Fig. 2 comprises a hollow conical outer casing with holes 9 and an inner skeleton 6 arranged in the cavity of the outer casing 9, the large end of the outer casing 9 is turned outward, and the small end is turned inward, the shape of one end of the inner skeleton 6 is a hexahedral hollow cavity, and the other end is a cuboid One end of the cuboid of the inner skeleton 6 protrudes from the hole at the small end of the outer casing 9; between the hollow cavity of the inner skeleton 6 and the inner cavity of the outer casing 9, a main rubber block 5 and a plastic plate 4 are arranged radially in sequence, wherein The plastic plate 4, the main rubber block 5 and the hexahedron of the inner frame 6 are vulcanized together, and then they are pressed into the inner cavity of the outer shell 9 through the pressure equipment, and the tension of the main rubber block 5 after being pressed is used to make the vulcanized body close to the The inner cavity of the outer casing 9 prevents the vulcanized body from protruding; the hollow cavity of the inner skeleton 6 is provided with a vibration damping block 3 and a limiting block 2 in sequence from right to left, and the limiting block 2 is in contact with the baffle plate 1, and the baffle plate 1 The combination nut is fixed on the big end of the outer casing 9 to prevent the limit block 2, the damping block 3 and the vulcanized body from protruding from the big end of the outer casing 9.

The main parts of the utility model that play the role of vibration damping are the main rubber block 5 and the vibration damping block 3. The main rubber block 5 is made of rubber material, and its shape is composed of two parts: "eight"-shaped surface and inverted "eight"-shaped surface. The shape of the inner cavity is matched with the outer hexagon of the inner frame 6, which can play the role of vibration reduction in the up and down and left and right directions. The plastic plate 4 is fixed on the "eight"-shaped surface of the main rubber block 5 and the inverted " The outer side of the "eight"-shaped surface plays the role of protecting the main rubber block 5; the shock absorbing block 3 is made of rubber material and mainly acts as a shock absorber in the front and rear directions; by adjusting the size of the inner skeleton 6 and the outer shell 9, the Adjust the size of the main rubber block 5; the thickness of the damping block 3 can also be adjusted by adjusting the thickness of the limit block 2. Therefore, the structural characteristics of the utility model determine that the suspension cushion assembly can be adjusted in a wide range The rigidity ensures the damping effect and service life of the whole assembly; the nut bracket 7 is riveted below the inner skeleton 6 of the utility model, and the nut bracket is equipped with a nut 8, mainly for the utility model and the engine block bracket Ease of assembly when connecting.
