SUMMERY OF THE UTILITY MODEL
Not enough to prior art, the utility model aims to solve the technical problem that a freight train exhaust system fixed bolster is provided to reach and promoted exhaust system fixed bolster mode, reduced the purpose of support fracture risk.
In order to solve the technical problem, the utility model discloses the technical scheme who adopts is:
this freight train exhaust system fixed bolster, including the fixed bolster body, the fixed bolster body is the crooked foundry goods board, is equipped with a set of connecting hole that is used for linking to each other with the derailleur on a tip of fixed bolster body, is equipped with a set of fixed orifices that is used for linking to each other with the exhaust system catalyst converter on another tip of fixed bolster body, is equipped with the strengthening rib on the fixed bolster between a tip and another tip.
Further:
the reinforcing rib and the fixed support body are of an integrated structure.
The reinforcing ribs are a group of reinforcing rib plates arranged side by side.
The connecting hole is a waist-shaped hole, and the fixing hole is a threaded hole.
The connecting holes and the fixing holes are arranged in a one-to-one corresponding mode, and one corresponding connecting hole and one corresponding fixing hole are formed between every two adjacent reinforcing rib plates.
Compared with the prior art, the utility model, have following advantage:
this freight train exhaust system fixed bolster structural design is reasonable, through use topological structure technique on the fixed bolster, makes fixed bolster intensity increase, save material, reduces weight, adopts the foundry goods technology simultaneously, has promoted exhaust system fixed bolster modal, has reduced the support fracture risk.

Fig. 2 is a schematic diagram of the fixing bracket structure of the present invention.
Fig. 3 is a schematic diagram of the fixing bracket structure of the present invention.
Fig. 4 is an assembly structure diagram of the fixing bracket of the present invention.
In the figure:
1. the device comprises a speed changer, 2 bolts, 3 fixing supports, 301 reinforcing rib plates, 302 threaded holes, 303 kidney-shaped holes and 4 catalysts.
Detailed Description
The following description of the embodiments of the present invention will be made in detail with reference to the accompanying drawings.
As shown in fig. 1 to 4, the fixing bracket for the truck exhaust system comprises a fixing bracket body, wherein the fixing bracket body is a bent casting plate, one end part of the fixing bracket body is provided with a group of connecting holes used for being connected with a transmission 1, the other end part of the fixing bracket body is provided with a group of fixing holes used for being connected with an exhaust system catalyst 4, and a reinforcing rib is arranged between the one end part and the other end part of the fixing bracket body.
The reinforcing ribs and the fixed support body are of an integrated structure; the fixed bolster body is the integrative support of cast iron, uses fixed bolster 3 to connect catalyst converter and derailleur for power assembly becomes integrative with the exhaust hot junction, has realized that the fixed bolster mode is high, no fracture risk, and the exhaust hot junction vibrates along with power assembly together.
The structure adopts the topology forming technology, and three strengthening ribs are set at the bending forming position, the connecting hole is a waist-shaped hole 303, and the fixing hole is a threaded hole 302. The catalyst welding support is connected with the cast iron fixing support through the bolts 2, the cast iron fixing support is provided with threaded holes, the assembling time is saved, the weight of the whole vehicle is reduced, and the number of standard parts is reduced. Cast iron fixed bolster and derailleur link adopt waist shape hole to make the fixed bolster can abundant tolerance in the X direction, and the fixed bolster rapid Assembly of being convenient for avoids causing the assembly difficulty because of the size chain discrepancy.
The reinforcing ribs are a group of reinforcing rib plates 301 arranged side by side; the connecting holes and the fixing holes are arranged in a one-to-one corresponding mode, and one corresponding connecting hole and one corresponding fixing hole are formed between every two adjacent reinforcing rib plates.
Preferred specific examples are:
the fixed support 3 adopts a casting structure, and three reinforcing ribs, two threaded mounting holes and two waist-shaped mounting holes are arranged on the fixed support.
In order to facilitate the convenient connection of the fixing support and the speed changer and the accurate positioning during the assembly, the speed changer and the support do not generate stress, and the fixing support is provided with two waist-shaped holes, so that the tolerance in the X direction is convenient to perform in the assembly process; in order to reduce the assembly time, the catalytic converter is connected with the fixed support, the fixed support is provided with a threaded hole, and the bolt is directly fixed on the cast iron fixed support through the catalytic converter support hole.
The utility model discloses the fixed bolster adopts topological shaping structure, and save material reduces weight, uses cast iron material, promotes fixed bolster connection structure's mode, and the fixed bolster endurance life obtains improving. The casting is adopted to avoid the problems of welding leakage, desoldering and insufficient welding of the support welding reinforcing rib, the part forming process is reduced, and the working time is saved; the threaded holes are adopted, so that nuts are saved, the number of standard parts is reduced, and the assembly time is saved.
The above-mentioned is only for the description of the preferred embodiments of the present invention, and the above-mentioned technical features can be combined at will to form a plurality of embodiments of the present invention.
The above description is for illustrative purposes only, and it is obvious that the present invention is not limited by the above embodiments, and various insubstantial improvements made by the concepts and technical solutions of the present invention or the direct application of the concepts and technical solutions of the present invention to other occasions without improvement are all within the scope of the present invention.
