Description

DESCRIPTION AN ENGINE MOUNTING FOR VEHICLES This invention relates the hub and the damper to each other, suitable for use in motor vehicles. It is related to an engine mount to which it is connected by a shape tie.

In motor vehicles, the engine is placed on the engine mounts fixed on the vehicle chassis. is stuck. Engine mounts, of vulcanized rubber and metal parts As it occurs, it dampens the engine vibration and therefore the vibration. It prevents the transmission of vibration-induced noise to the chassis. especially heavy Damage to engine mounts in commercial vehicles is very common. Path conditions, engine characteristics and driver operating conditions, engine and transmission These parts, which carry the duo and dampen the incoming vibrations, are quite forcing.

European Patent No. EP1690722 in the state of the art In its application, the damper includes a channel circumferentially. However, this The form of the hub located in the middle of the damper in the document is cylindrical.

Another document in the state of the art, DE2228394 It is a German patent application. In this document, the damper has a curved surface. has. However, in this document, the metal core in the middle of the damper it is cylindrical.

GB638988, which is another document in the state of the art. In the British Patent application, the damper placed in a casing is described and also in this document, the metal core has a cylindrical structure. it seems to be.

In an application in the state of the art, it is located in the damper. The area core is shaped like a circular cone with a truncated top. metal in this application rubber, which is the material from which only the damper is produced, in the core draw forces It works together with the bonding element between the metal and the on the other hand, rubber is crushed due to the angled design of the metal core. is working. Because of this design of the metal core, the damper is often It is damaged and creates negativities for the vehicle and the driver. In this case too vibrations cannot be prevented, therefore, vibrations can be avoided in both other systems. damage occurs, as well as the driver and passengers in the cabin. they are disturbed (Figure 1).

The aim of this invention is to create a motor that works with a shape bond under all forces. the realization of the wedge.

In order to achieve the purpose of this invention, the first request and the dependent The engine mount, as defined in the claims, is a lateral a core having at least one recess and/or protrusion on its surface. This With the invention, the strength of the engine mount that connects the engine and transmission couple to the chassis and the working characteristics are improved.

Thanks to the recess and/or protrusion on the lateral surface of the hub, both the head of the hub shape in the material from which the damper is produced, under tensile forces. By creating the bond, it is provided to work just like an anchor.

Surface area thanks to the recesses and protrusions on the lateral surface of the hub therefore, since the contact surface area with the damper increases, the damper used amount is also increasing. Increasing the amount of damper engine mount It provides more damping of vibrations and blows passing over it.

This is the sound, vibration and hardness (Noise, Vibration, Harshness) parameters. It provides customer satisfaction by making a positive impact directly. Also lateral increased surface area of the surface, with the core produced from metal and rubber better and more surface area adhesion of the produced damper. it provides.

With this invention, frequent part damage is prevented and the driver and passengers are protected. more comfortable travel is ensured, repair/service fees are reduced, raw material consumption and time losses are minimized.

An engine mount realized to achieve the purpose of this invention is presented in the attached figures. has been shown, from these figures; Figure 1 - Side and A-A section of the engine mount from the previous art is the view.

Figure 2 - The subject of the invention is the side view of the wedge.

Figure 3 - is the view of section A - A in Figure 27.

Figure 4 - Side view of the hub.

Figure 5 - is the view of section A - A in Figure 47.

The parts in the figures are numbered one by one and the corresponding numbers are given below. 1. Engine mount damper Lateral surface In motor vehicles, the engine mount (1), which is attached to the chassis, on which the engine is fixed, a damper (2), placed in the damper (2), surrounded by the damper (2) a hub (3). The engine mount (1) is on the hub (3), a base (4), a the ceiling (5) and the lateral surface (6) connecting the floor (4) and the ceiling (5). it has at least one recess (7) and/or protrusion (8) on the lateral surface (6). Recess By means of (7) and/or protrusion (8), the contact surface of the hub (3) with the damper (2) area is increased. In this way, the hub (3) and the damper (2) are better and more It provides adhesion on a large surface area. Thus, the belly (3) It is shaped almost like an anchor inside the damper (2) in both draft forces. By working connected, it prevents the damper (2) from separating and tearing. (Figure 2 and Figure 3).

In the preferred embodiment of the invention, the damper (2) is made of rubber. and the core (3) is made of metal material.

The engine mount (1) has a recess (7) and a recess on the lateral surface (6) of the hub (3). (7) includes an adjacent protrusion (8). Indent in the preferred embodiment of the invention (7) and protrusion (8) are curved. In this way, the damper (2) made of rubber deformations originating from the hub (3) are prevented.

In the preferred embodiment of the invention, the protrusion (8) is located between the two recesses (7). remains. In this way, both pressure and traction on both surfaces of the protrusion (8) forces act and the separation of the damper (2) from the hub (3) is prevented.

In one embodiment of the invention, the recess (7) is in the form of a groove. Groove of the recess (7) Thanks to its form, it completely fills the inside of the rubber recess (7). The surface area where the damper (2) and the hub (3) come into contact with each other is increased.

In this way, the hub (3) forms a stronger shape bond with the damper (2) and it works together like an anchor. Thus, both the engine mount (1) strength is increased and sound, noise and hardness parameters are improved. vehicle characteristics are affected positively (Figure 4 and Figure 5).

The recesses (7) and protrusions (8) surround the entire lateral surface (6) of the hub (3) it wraps around.

In the preferred embodiment of the invention, the base (4) and ceiling (5) of the core (3) are circular. and the ceiling (5) is wider than the floor (4).

In one embodiment of the invention, the hub (3) and the damper (2) are vulcanized and a are brought together.

The engine mount (1) prevents vibrations from the engine reaching the chassis and the vehicle cabin. hinders. With this invention, the metal core (3) and the rubber damper (2) can only be It works not only with the adhesive element, but also on a shape basis. Like this vibrations are prevented and both damages caused by vibration and In addition, the driver and passengers in the cabin are affected by the vibration and become uncomfortable. is blocked. Thanks to the invention, it connects the engine and transmission couple to the chassis. The strength and operating characteristics of the engine mount (l) have a positive effect. is being improved.

In the engine mount (l) which is the subject of the invention, both the compression and traction forces of the hub (3) under it, creating a shape bond in the rubber material from which the damper (2) is produced. work is provided. In addition, both the strength of the engine mount (l) and the amount of rubber used is increased. The amount of rubber material increasing the vibrations and impacts on the engine mount (l) more provides damping. This is the sound, vibration and hardness parameters. has a direct positive effect.

With this invention, frequent part damage is prevented and the driver and passengers are protected. more comfortable travel, reduced repair/service fees, raw material consumption and time losses are minimized.
