Abstract

PURPOSE: An antivibration structure of an air compressor for bus is provided to absorb and block the vibration generated by the operation of the compressor and the force pulled toward an engine by a supporting bracket between the compressor and a chassis frame. CONSTITUTION: An antivibration structure of an air compressor for bus includes a supporting bracket(5). The supporting bracket includes an upper plate(5a) for fixing the compressor, and a lower plate(5b) fixed to chassis frames(6) which form the vehicle body part. Mounting elements(5') are coupled with the upper and lower plates while keeping an interval between the upper and lower plates, and generate force to the lower plate against the upper plate. The mounting elements are formed of rubber to increase the vibration absorbing effect. A compressor(2) is secured on the supporting bracket, so that the vibration generated by the compressor is not transmitted to the vehicle room.

Description

Air conditioner compressor vibration structure for bus {Air conditioner's compressor vibration structure in bus}

The present invention relates to a bus air conditioner compressor dustproof structure, and more particularly, to a bus air conditioner compressor dustproof structure that generates a repulsive force against external force applied during engine operation to absorb and reduce vibration.

In general, the compressor (2) for compressing the refrigerant to increase the pressure and enthalpy when operating the air conditioner, as shown in Figure 1 showing the engine room of a large vehicle such as a bus, the chassis frame (6) forming a body at intervals from each other While being fixed to the support bracket (5) fixed via the fixing member (5 '), such as bolts, while the power of the engine (1) via the idle pulley (3') of the swing arm (3) through the belt ( 4, 4 ') to operate.

However, the compressor 2 and the engine 1 are disposed on both sides of the swing arm 3, and due to structural problems in the installation interval thereof, the engine 1 is provided through the belt 4 on the engine 1 side. 2, the horizontal force (F ') of the swing arm (3) toward the engine (1) by the pressing force (F) toward the engine (1) toward the engine 1, as shown in FIG. The vertical component F ″ in the downward direction is generated, and accordingly, the moment 2 in the counterclockwise direction is formed in the compressor 2 by the pressing force F, which causes vibration.

In addition, the vibration of the compressor (2) in which the moment (M) is generated is transmitted to the support bracket (5) mounted as it is while the vehicle through the chassis frame 6 coupled via the fixing member (5 ') as a vehicle. It is delivered to the room has the disadvantage of lowering the ride comfort.

Accordingly, the present invention has been invented in view of the above, and the vibration generated by the operation of the compressor and the force pulled toward the engine are absorbed and blocked by the support bracket between the compressor and the chassis frame, and the vibration is transmitted to the vehicle interior. Its purpose is not to be.

The present invention for achieving the above object, the support bracket for mounting the compressor that is operated by receiving the power of the engine through the belt and the upper plate for fixing the compressor, and the chassis to form a body spaced apart from each other in the chassis frame The lower plate is fixed and the mounting member is coupled to maintain the spacing of the plate while generating a force on the lower plate portion to face the force generated on the upper plate portion.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figure 3 shows a block diagram of the air conditioner compressor dustproof structure for the bus according to the present invention, the present invention is the power of the engine 1 through the idle pulley (3 ') of the swing arm (3) belt (4, The compressor (2 ') received and operated through 4') is mounted on the support bracket (5) fixed to the chassis frame (6) arranged at intervals, and the support bracket (5) is mounted on the compressor (2). The upper plate 5a to be fixed, the lower plate 5b fixed to the chassis frame 6 arranged at intervals while forming a vehicle body, and the upper plate 5a while being coupled to maintain the gap between the plates 5a and 5b. And a mounting member 5 "generating a force on the lower plate 5b so as to oppose the force generated on the portion.

Here, although the mounting member 5 "may use a magnetic fluid therein to increase its vibration insulation effect, it is preferable that the mounting member 5" is made of a conventional rubber.

One end of the upper lower plates 5a and 5b is opposed to each other, that is, one end of the upper plate 5a forms a lower bent end 5a 'bent in an inclined downward direction to form the lower plate 5b. One end is formed with the upper bent end (5b ') is bent slightly in the upward direction and is fixed to each other via the mounting member 5 "in the gap therebetween.

On the other hand, the lower plate 5b is provided with fixed ends 5b "protruding at intervals from each other to fix the mounting member 5" having one end fixed to the upper plate 5a. ) Can be formed in plural numbers, but it is of course preferable to form two pieces at intervals from each other.

Hereinafter, the operation of the present invention will be described in detail with reference to the accompanying drawings.

According to the present invention, when the compressor 2 receives the power of the engine 1 from the belt 4 through the belt 4 'coupled to the idle pulley 3' of the swing arm 3, the engine 1 The support arm provided between the compressor (2) and the chassis frame (6) acts on the swing arm (3) part of the swing arm (3) toward the engine (1) through the belt (4) on the side. In (5), the reaction force against the pressing force F is generated together to absorb and block the vibration transmitted from the compressor 2 toward the chassis frame 6 so as not to be transmitted to the vehicle interior.

That is, as shown in FIG. 3, the belt 4 is positioned on the swing arm 3 in the upper portion of the support bracket 5 by the pressing force F toward the engine 1, respectively. The horizontal component (F ') and the vertical component (F ") in the downward direction and the counterclockwise moment (M) of the compressor (2) by the pressing force (F) is formed, while the support bracket (5) A horizontal repulsion force P 'and a vertical repulsion force P are also generated at the lower portion of the compressor against the horizontal component F' and the vertical component F ", as well as the counterclockwise moment M of the compressor 2. A clockwise moment M 'is generated against.

In this way, the forces generated so as to face each other on the support bracket 5 are absorbed by the mounting member 5 "provided between the upper plate 5a and the lower plate 5b of the support bracket 5. The vibration generated in the compressor 2 through the pressing force F generated by the belt 4 coupled to the swing arm 3 toward the engine 1 is thus absorbed. Of course, it is not delivered to the interior.

As described above, according to the present invention, the support bracket located between the compressor and the chassis frame is composed of an upper plate and a lower plate, and a mounting member interposed therebetween to absorb vibrations, by the pressing force acting toward the engine during the operation of the compressor. The generated vibration is blocked through the support bracket and is not transmitted to the vehicle interior, thereby improving the merchandise of the vehicle.
