Abstract
The utility model provides a fixed device used for fixing an exhaust-gas silencer. The fixed device used for fixing the exhaust-gas silencer comprises at least a pair of anchor ears. The anchor ears are connected through an upper semi-circle anchor ear and a lower semi-circle anchor ear. A bending board used for installation and fixing is arranged at the bottom of the lower semi-circle anchor ear. Installation holes used for installation and fixing are formed in two ends of the bending board which is provided with a reinforcing rib. The fixed device used for fixing the exhaust-gas silencer is mainly used for fixing the exhaust-gas silencer, simple in structure, convenient to install, low in manufacturing cost, stable in performance, and high in reliability. The exhaust-gas silencer is not prone to shaking.
Description
Technical field
The utility model relates to the exhaust muffler of bus engine, and is specifically a kind of for the fixing anchor fitting of exhaust muffler.
Background technology
At present, the mounting structure of engine exhaust muffler commonly used is mainly fixed noise silencer by anchor ear, adopts bolt of rear end plate to be connected also fastening with the support that is welded in advance on the skeleton.The installation Rubber shock-absorbing pad reduces the muffler vibration in the Vehicle Driving Cycle process between anchor ear and the support.Vehicle can constantly accelerate and slow down in the process of moving, makes noise silencer the impulsive force of fore-and-aft direction occur; Vehicle is when turning, and the side force that noise silencer is subject to is larger, the easy double swerve of noise silencer, because support and anchor ear connection mode require stent length to be greater than the radius of anchor ear, so be welded in advance the support arm length on the skeleton, the moment that support bears is large; Simultaneously, on the stressed point of connection that all concentrates on again two supports and skeleton.In the reality operation, noise silencer occurs easily rock the phenomenon that ruptures with support.
The utility model content
The purpose of this utility model is to provide a kind of fixedly anchor fitting of exhaust muffler that is used for of simple in structure and stability and safety, the utility model has adopted following technical scheme: a kind of for the fixing anchor fitting of exhaust muffler, comprise at least 1 pair of anchor ear, described anchor ear is formed by connecting by upper and lower semicircle anchor ear, described lower semi-circular anchor ear bottom is provided with two ends for the bending plate that is connected with body framwork, the two ends of described bending plate are provided be used to the mounting hole that installs and fixes, and described bending plate is provided with reinforced rib.
The utility model beneficial effect: the anchor fitting that a bending plate is used for connecting exhaust muffler is installed in the bottom at the semicircle anchor ear in the utility model, the two ends of anchor ear can be fixedly connected on the skeleton of exhaust muffler, increase the point of connection with skeleton, so not only Lateral Resistance is more stable, and the support of pre-installing on the skeleton when fixed installation is shorter, exhaust muffler is difficult for rocking, and is not easy to occur the situation of support fracture.

The specific embodiment
Be described in further detail below in conjunction with accompanying drawing:
Be illustrated in figure 1 as in the prior art scheme drawing of anchor fitting when being used for fixing exhaust muffler, mainly will arrange noise silencer by anchor ear 2 and fix, the employing bolt of rear end plate is connected also fastening with support 3 on being welded in advance body framwork 5.Installation Rubber shock-absorbing pad 4 reduces exhaust muffler 1 vibration in the Vehicle Driving Cycle process between anchor ear 2 and the support 3.Vehicle can constantly accelerate and slow down in the process of moving, makes noise silencer the impulsive force of fore-and-aft direction occur; Vehicle is when turning, and the side force that noise silencer is subject to is larger, the easy double swerve of noise silencer.As shown in Figure 2, be welded in advance support 3 arm lengths on the skeleton, the moment that support bears is large; Simultaneously, on the stressed point of connection that all concentrates on again two supports 3 and body framwork 5.In actual use, exhaust muffler 1 occuring easily rocks the phenomenon that ruptures with support 3.
Structural scheme of mechanism of the present utility model as shown in Figure 3, comprise anchor ear 2, anchor ear 2 is formed by connecting with bolt and lower anchor ear 2-1 by upper anchor ear 2-2, bending plate 6 that is used for connecting body framwork of the bottom welding of lower anchor ear, the mounting hole of the two ends of bending plate 6 for being used for installing and fixing, in order to increase fixing intensity, at reinforced rib 7 of bending plate 6 welding.Such as Fig. 4,5 are depicted as the utility model is used for the fixedly structural representation of exhaust muffler, at first on body framwork 5, weld in advance 4 supports 3, then use two anchor ears 2 as shown in Figure 3, be separately fixed on the exhaust muffler 1, as shown in Figure 6, then will be fixed on for the contiguous block 8 of connection bracket 3 mounting hole of bending plate 7 with nut, then contiguous block 8 is fixed on the support 3, and Rubber shock-absorbing pad 4 placed space between contiguous block 8 and the support 3, present embodiment medium-height trestle 3 is U-shaped support, shown in Figure 7 is block diagram after the utility model is installed, can find out very intuitively the effect of the utility model in fixing exhaust muffler, fixing with anchor fitting in the utility model after, when Vehicle Driving Cycle, the weight of exhaust muffler 1 is distributed to power on the body framwork 5 by four attachment points.As mounting bracket 3 cantilever ends, so support 3 can bear very large moment.Simultaneously, mounting bracket 3 is in exhaust muffler 1 both sides, between two mounting brackets 3 of every side larger distance is arranged again, therefore, no matter be that vehicle is accelerating, slowing down, or when turning, the power with all directions that mounting bracket 3 all waits is disperseed away very much, has guaranteed the reliability of exhaust muffler 1 installation.
Above-described embodiment is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that those of ordinary skills make the technical solution of the utility model all should fall in the definite protection domain of the utility model claims.
