Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mount bracket for a vehicle air suspension device having an air suspension device having a rigid axle.

[0002]

2. Description of the Related Art For example, referring to FIG. 3 (torque rod is omitted), in the case of an air suspension device having a rigid axle 10, a rigid axle 10 and a frame (joist) 3 provided on a vehicle body 1 are formed. Attach the air bellows 4 forming an air spring by putting compressed air in between,
Referring to FIG. 4, in order to position the rigid axle 10 with respect to the vehicle body 1 and prevent the axle 10 from turning due to driving torque or brake torque with respect to the rigid axle 10, the upper torque rod 20 and the lower torque rod 21 are connected to the vehicle body. Techniques for placing between 1 and axle 10 are known. Here, reference numeral 2 is a tire house, 12 is a lower rod mounting seat of the axle 10, 13 is a floor surface, 15 is a tire, 17 is an upper rod mounting seat, 18 is an upper rod bracket, 19 is a shock absorber, and 20a and 21a are rod ends. Each mounting member is shown.

[0003]

The lower rod 2
1 is that two rods are installed diagonally so that the mounting position on the vehicle body side is close to the side of the vehicle body, the upper rod 20 is mounted at a position higher than the axle 10, and one is mounted from the center of the vehicle Is common.

However, in the case of a bus, if the floor is lowered and the floor is lowered, if the upper rod 20 is set at a high position, it interferes with the vehicle body. Furthermore, in the case of a no-step low-floor bus having no step at the entrance, the upper rod 20
Placement is extremely difficult.

Accordingly, it is an object of the present invention to provide a mount bracket for an air suspension device in which an upper rod and a vehicle body do not interfere with each other even in a vehicle body having a low floor such as a low floor bus.

[0006]

According to the present invention, there is provided a bracket for an air suspension system for a vehicle having an air suspension system having a rigid axle, wherein a mount is provided between an air bellows mounted on a vehicle body and the rigid axle. A bracket is provided, and the mount bracket has an air bellows receiver for attaching the air bellows at an upper end and a mounting seat for attaching to the axle at a lower end, and the air bellows receiver and the mounting seat are connected by a connecting member. The connecting member is provided with a rod bracket for attaching one end of an upper rod of the suspension and a shock absorber bracket for attaching one end of a shock absorber.

According to the present invention, the upper rod is attached to the mount bracket provided between the air bellows and the axle, so that there is no interference between the vehicle body and the rod, and the shock absorber is also attached to the mount bracket. be able to.

Further, the present invention can cope with a bus body having an extremely low floor such as no step.

Therefore, the layout of the air suspension of the low floor bus can be easily and functionally made, the torque rod operates reliably, and if a lateral rod is required for lateral positioning, it is arranged as before. And the arrangement of the shock absorber is not hindered.

[0010]

Embodiments of the present invention will be described below with reference to the drawings.

In the drawings, members having the same functions as those of the prior art are denoted by the same reference numerals, and detailed description thereof will be omitted.

FIG. 1 shows a front view of a front air suspension of a low-floor type bus. An air bellows 4 of an air suspension is attached to a vertical joist 3 of a bus body 1 of the bus. It is attached to a bellows receiver 5 provided on the upper part of the mount bracket.

A mounting seat 6 provided below the mount bracket 7 is fastened to a spring seat 11 of a front axle 10 which is a rigid axle. Referring to FIG. 2, the mount bracket 7 has the bellows receiver 5 and the mounting seat 6 welded to each other at both ends of the first connecting member 7a.
Is welded to one end 8a of an upper rod bracket 8 to which an unillustrated upper rod is attached.

Further, the other end 8b of the upper surface of the upper rod bracket 8 is connected to a bellows receiver 5 by a third connecting member 7c.
The other end 8c of the lower surface is connected to the mounting seat 6 and the fourth connecting member 7d, and each is welded.

An intermediate portion of the upper rod bracket 8 is welded to the bellows receiver 5 by a second connecting member 7b and to the mounting seat 6 by a fifth connecting member 7f. A U-shaped notch 9 is provided on the front surface (front side of the vehicle) of the upper rod bracket 8, and a screw hole 8g for fastening an upper rod mounting member for mounting the upper rod is provided on the front surface on both sides thereof. I have.

A shock absorber bracket 14 for attaching a lower end of a shock absorber (not shown) is provided on a rear surface of the upper rod bracket 8.

Hereinafter, the operation will be described. The bellows 4 is attached to the joist 3 provided at the position of the tire house 2 and the front axle is attached via the bracket 7, so that the floor 13 of the bus can be sufficiently lowered, and For example, the floor surface in this case can be set to 320 to 340 m / m.
The lower torque rod can be attached to the front axle 10 as before, and the axle side, which is one end of the upper torque rod,
It can be fastened to the letter-shaped notch 9 by a bolt with a screw hole 8g. In this case, the two rods can be used to securely and securely arrange the vehicle body 1 without interference.

The lower end of a shock absorber (not shown) may be attached to the shock absorber bracket 14.

Therefore, the torque rod can be reliably operated, and when the lateral rod is required for lateral positioning, it can be disposed as before, and the arrangement of the shock absorber is not affected. Never do.

[0020]

The present invention is configured as described above,
The following excellent effects can be obtained. (1) Since the upper rod is attached to the mount bracket provided between the air bellows and the axle, there is no interference between the vehicle body and the rod. (2) A shock absorber can be attached to the mount bracket. (3) It can easily cope with a bus body having an extremely low floor such as no step. (4) Therefore, the layout of the air suspension of the low floor bus can be easily and functionally performed.
