[0002]

2. Description of the Related Art FIG. 4 shows an arrangement structure of a conventional pressure type reservoir tank. Reference numeral 21 denotes an engine unit horizontally disposed in an engine room E / R. The engine unit 21 has both end portions. An engine side mount bracket 22 is fixedly mounted on the rear surface of the engine side mount bracket 22 fixed to a vehicle body side mount bracket 24 fixed on a front side member 23 via an engine mount 25. -Mounted on R.

The engine-side mount bracket 22 is fixedly installed at a position above the rear surface of the engine unit 21 in accordance with the height of the engine mount 25 and extends straight to the side, while the vehicle-body-side mount bracket 24 and the engine are mounted. The mount 25 corresponds to the projecting position of the engine side mounting bracket 22 and the strut tower 26.
Is disposed on the front side member 23 in close proximity to.

At one end of the engine unit 21, for example, at the back of the right end, the water pump 2 is located below the fixed position of the engine mount bracket 22.
7 is provided, a reservoir tank 29 is attached to the front portion of the strut tower 26 on the shelf portion 28a of the hood ridge panel 28 on the side where the water pump 27 is arranged, and the connection port 29a of the reservoir tank 29 and the water are installed. A hose 30 made of a heat-resistant elastic material is communicatively connected to the inlet 27a of the pump 27 to form a so-called pressurized reservoir tank.

This similar structure is, for example, "MECHANICAL 405".
Supplement Nr.1 "(published by AUTOMOBILES PEUGEOT, 1988.02), A4.003 to 004.

[0006]

As described above, the vehicle body side mounting bracket 24 and the engine mount 25 on the front side member 23 are arranged close to the front side portion of the strut tower 26, and the vehicle body side mounting bracket 24, Since there is no space for disposing the hose 30 between the engine mount 25 and the strut tower 26, the hose 30 connected to the connection port 29a at the lower front side of the reservoir tank 29 is temporarily raised at the disposition part of the engine mount 25. , The engine side mount bracket 22 is laid across the coupling part in the front-rear direction, and is routed under the fixed part of the engine side mount bracket 22 on the back of the engine unit 21 to the inlet 27a of the water pump 27. I am trying to connect.

Since the hose 30 is arranged so as to stand up at the portion where the engine mount 25 is arranged in this way, it is unavoidable that a pressure loss of the circulating cooling liquid occurs at this portion of the hose 30, and the water pump 27 causes cavitation. It can happen.

In the case of a right-hand drive vehicle, it is desirable that the brake master cylinder 33 should be arranged on the right side of the dash panel 32, which is originally close to the brake pedal (not shown).
As described above, the engine-side mount bracket 22 is fixed to the upper portion of the back surface of the engine unit 21 in accordance with the ground height of the engine mount 25, and the engine-side mount bracket 22 and the brake master cylinder 3 are provided.
It becomes difficult to set a sufficient non-interference interval L between the first and second positions.

When the position of the dash panel 32 is retracted to secure the non-interference distance L, the living space of the vehicle compartment is narrowed by that amount, which is not practical. Therefore, the brake master cylinder 33 is dashed. Panel 32
Inevitably, the brake pedal and the brake master cylinder 33 need to be connected by an operating force transmission means such as a link (not shown), which is disadvantageous in terms of structure and cost. Will be.

On the other hand, for this reason, it may be possible to mount the reservoir tank 29 on the shelf 28a of the left hood ridge panel 28, but on the left side of the dash panel 32, the inlet and outlet of the heater unit (not shown) are provided. Since two heater hoses for use are arranged, if the hose 30 of the reservoir tank 29 is additionally arranged in addition to this, the installation space cannot be taken up, and in this case also, it is necessary to retract the position of the dash panel 32. Moreover, when the battery is mounted on the front portion of the shelf portion 28a of the left hood ridge panel 28, the volume of the reservoir tank 29 is reduced and the shape is restricted. Realization is difficult.

Therefore, the present invention does not cause pressure loss of the circulating cooling liquid in the hose, and can shorten the hose length as much as possible to simplify the hose layout. (EN) A hose disposition structure of a pressurized reservoir tank capable of installing a brake master cylinder on the engine side mount bracket fixed part side without retreating the position.

Moreover, since the supporting wall is formed so as to rise from the front edge portion of the lower mounting flange close to the rear surface of the engine unit, a sufficient non-interference interval with the brake master cylinder can be secured at the back of the engine side mounting bracket. It is possible to install the brake master cylinder on the side where the water pump is arranged.

As a result, the brake pedal and the brake master cylinder can be directly connected to each other, and the layout of the brake system can be easily and cost-effectively constructed.

The hose extending from the reservoir tank can be attached to the water pump by utilizing the vertical offset space formed between the brake master cylinder and the water pump. It will not be hindered.

A third aspect of the present invention is characterized in that the engine mounts according to the first and second aspects are arranged at substantially the same longitudinal position as the principal axis of inertia of the engine unit.

According to the third aspect of the present invention, the engine mount is arranged on the principal axis of inertia of the engine unit. Therefore, it is possible to maximize the vibration damping and vibration damping effects of the engine mount and to reduce the vehicle noise. The vibration performance can be improved.

According to a fourth aspect of the present invention, the vehicle-body-side mounting brackets according to the first to third aspects are arranged in such a manner that they are bridged up in the front-rear direction across the kick-up portion of the front side member and joined together. It has a feature.

According to the fourth aspect of the present invention, since the vehicle body side mount bracket that rises in a bridge shape is joined and arranged so as to straddle the kick up portion of the front side member where stress tends to concentrate, the front side member is arranged. The beam rigidity can be increased, and the crushing buffer stroke at the time of a frontal collision of the vehicle can be sufficiently secured to improve safety.
