Description

[Detailed Description of the Invention] The present invention relates to a support structure for a front-wheel drive transverse engine, and is particularly simple in structure and low in cost to suppress engine roll.

In recent years, front-wheel drive passenger cars have become mainstream as they offer a spacious interior and are light in weight, but in many front-wheel drive cars, the engine is mounted horizontally in order to make the engine compartment more compact. . In this case, the engine rolls back and forth due to the torque reaction force acting on the engine, so generally the front and rear parts of the engine are connected to the vehicle body's headlamp support, dash panel, etc. via insulators. ,
These insulators are designed to prevent roll generated in the engine from being transmitted to the vehicle body.

However, because a radiator and engine auxiliary equipment must be placed in front of the engine, there is often little space for installing an insulator, especially in small passenger cars. In such a case,
It is also possible to connect the upper and lower parts of the engine to the dash panel or floor pan of the car body via an insulator, but due to layout issues within the engine compartment, it is not possible to connect the floor pan and the engine via an insulator. Some things are impossible.

From this perspective, the present invention focuses on the fact that the casing that supports the gear shift lever and the engine are connected via an extension rod.
To provide an engine support structure which allows this extension rod to also function as a roll stopper without newly providing a special roll stopper, and is designed to be compact and cost-reduced at the same time.

The configuration of the engine support structure of the front wheel drive vehicle of the present invention that achieves this purpose is that the front wheels are mounted on the front part of the vehicle body, and the output shaft connected to the front wheels through the transmission protrudes from one side of the front wheels. In the drive vehicle, the tip of the support arm protruding from the engine is connected to a bracket provided on the dash panel via an insulator;
The present invention is characterized in that an extension rod that supports a gear shift lever and connects the engine to a casing attached to the floor pan is connected to a bracket provided on the floor pan via an insulator. .

Hereinafter, an embodiment of the engine support structure for a front wheel drive vehicle according to the present invention will be described in detail with reference to FIG. 1, which shows a schematic cross-sectional structure thereof, and FIG. 2, which shows its front shape. An upwardly projecting bracket 14 is integrally fixed to an engine 13 whose output shaft (not shown) is connected to the front wheels 11 via a transmission 12 and projects to one side of the front wheels 11. The other end of the support arm 15, one end of which is connected to the tip, is connected to the dash panel 1.
It is connected to a bracket 17 provided integrally with the housing 6 via an insulator 18 formed of an elastic member such as rubber. On the other hand, a casing 21 supporting the base end of a gear shift lever 20 protruding from the floor pan 19 into the vehicle interior is integrally fixed to the floor pan 19, and a shift rod 22 connected to the gear shift lever 20 is connected to the transmission 12. guided within. The extension rods 23 and 24 of this embodiment have a two-part structure, and are formed into a single rod shape by a connecting fitting 25. One end of one extension rod 23 is connected to the lower end of the engine 13, and the other end is connected to a bracket 26 integrally projecting from the floor pan 19 through an insulator 27 formed of an elastic member such as rubber. It is stopped. Further, one end of the other extension rod 24 is connected to the other end of this one extension rod 23 via a connecting fitting 25, and the other end of the other extension rod 24 is fixed to the casing 21.

In this embodiment, the extension rods 23, 2
Although the extension rod 4 is of a two-part type, it may be a single rod-like one, and in any case, the middle part of the extension rod is connected to the bracket 2 through the insulator 27.
Any structure that can be connected to 6 is sufficient.

Therefore, even if the torque reaction force acts on the engine 13 and causes the engine 13 to roll back and forth, the engine 13 is supported by the dash panel 16 and floor pan 19 of the vehicle body via the pair of insulators 18 and 27. Roll is suppressed and the accompanying vibrations are not transmitted to the vehicle body. If there is sufficient space, the engine 13 may be further connected to a headlamp support (not shown) via an insulator.

According to the engine support structure for a front wheel drive vehicle of the present invention, the middle part of the extension rod for fixing the gear shift lever is connected via an insulator to the bracket provided on the floor pan. The rod can also be used as an engine roll stopper, eliminating the need to provide a new roll stopper, saving space, and suppressing engine roll without significantly increasing costs.
