Abstract
The utility model provides a flexonics muffler that motor tricycle and diesel oil tricycle agricultural vehicle used, includes blast pipe 1, hush pipe 2, is provided with the corrugated metal pipe 5 with blast pipe coaxial line and mutual intercommunication on the blast pipe, the utility model discloses a blast pipe department before hush pipe sets up corrugated metal pipe. Compared with the silencing pipe in a flange connection mode, the connecting structure can realize universal flexible connection and can play a role in flexible connection in any direction. The vibration of the engine can be effectively eliminated at the front end of the silencing pipe, and the connecting bolt at the connecting part of the engine and the frame is prevented from loosening or breaking; prevent fatigue fracture of the muffler caused by vibration. The utility model discloses still reducible manufacturing cost is compared with the ring flange is connected.
Description
Technical field
The utility model relates to motor tricycle or the used baffler of diesel oil three wheeled transport vehicle used for farm, refers to the baffler that flexibly connects that a kind of motor tricycle and diesel oil three wheeled transport vehicle used for farm use especially.
Background technique
Existing motor tricycle or the used baffler of diesel oil three wheeled transport vehicle used for farm mostly are made of outlet pipe and the hush pipe that is connected to one with it, and the outlet pipe front end is connected with motor, and the middle part of outlet pipe is connected with vehicle frame with hush pipe.In engine operation process, the vibration that is produced can cause following consequence to this baffler: 1, the loosening easily or fracture with the connecting bolt of motor joint and vehicle frame joint; 2, cause the fatigue fracture of baffler.The person skilled in art addresses this problem the structure that adopts the minicar baffler is also arranged, outlet pipe middle part at the baffler front end installs flange plate additional, be provided with the wear-resistant pad of half garden shape in the centre of flange plate, be used for eliminating the adverse effect of baffler being brought because of vibration.Still there is following technological deficiency in this linkage structure in actual motion: 1, this linkage structure can not universally flexibly connect, and can only flexibly connect at single symmetry direction, can not be effectively the front end of the vibration of motor elimination at hush pipe.2, the wear-resistant pad between the flange plate weares and teares easily, causes the gas leakage of wear-resistant pad joint, and the noise reduction quality is descended.3, cost is higher.
Summary of the invention
Technical problem to be solved in the utility model just provide a kind of motor tricycle and diesel oil three wheeled transport vehicle used for farm used flexibly connect baffler, outlet pipe place before hush pipe be provided with can universal connection flexible connecting device, effectively outlet pipe place before hush pipe is eliminated in the vibration of motor.
For solving this technical problem, technical solution adopted in the utility model is: the described baffler that flexibly connects comprises outlet pipe, hush pipe.Outlet pipe is provided with and outlet pipe coaxial line and the metal bellows that is interconnected.Between any two sections of outlet pipe, be connected with and outlet pipe coaxial line and the metal bellows that is interconnected.Be connected with and outlet pipe coaxial line and the metal bellows that is interconnected at an end of outlet pipe.
The utility model is that the outlet pipe place before hush pipe is provided with metal bellows.The convex-concave ripple of metal bellows can be realized the bending of metal bellows to either direction, and certain telescopicing performance is arranged.This linkage structure is universal flexibly connecting as link, can play the effect that flexibly connects in either direction.It can not only be effectively the front end of the vibration of motor elimination at hush pipe, and can eliminate swing because of outlet pipe and cause damage with the motor joint, avoid loosening or fracture, prevent the fatigue fracture of the baffler that causes because of vibration with the connecting bolt of motor joint and vehicle frame joint.The utility model is connected with flange plate to be compared and can reduce production costs.
Description of drawings
Fig. 1 is a structural drawing of the present utility model.
Embodiment
Shown in 1.The described baffler that flexibly connects comprises outlet pipe 1, hush pipe 2, and outlet pipe is provided with and outlet pipe coaxial line and the metal bellows 5 that is interconnected.On outlet pipe and hush pipe, be respectively equipped with the connecting plate 3,4 that is connected with vehicle frame.
In the actual production, be between any two sections of outlet pipe, be connected with one with outlet pipe coaxial line and the metal bellows that is interconnected.Metal bellows also can be located at outlet pipe one end and be connected with outlet pipe, promptly be connected with between outlet pipe and the hush pipe one with outlet pipe coaxial line and the metal bellows that is interconnected.Or between outlet pipe and motor, be connected with one with outlet pipe coaxial line and the metal bellows that is interconnected.
