Abstract
An improved truck silencer hanging device is characterized in that two silencer hoops are arranged at the middle section of a silencer along the outer cylindrical surface; the silencer hoops are made of steel plates and are made to be a ring shape with an opening respectively; bolt mounting holes are machined in the plane formed by two edges extending from each opening; each silencer hoisting frame is made of a steel plate and bent to be right angle-shaped; the two silencer hoops are respectively connected to the lower ends of the two silencer hoisting frames by bolts and nuts; after buffer rubber gaskets are cushioned at the upper ends of the two silencer hoisting frames, the two silencer hoisting frames are respectively arranged at the lower wing surface of a frame left longitudinal beam by bolts and nuts; the vibration can be greatly reduced and the service life of an exhaust pipe and the silencer can be prolonged by the buffer rubber gaskets. The outlet of a silencer exhaust pipe at the rear end of the silencer points to the lower rear direction of a vehicle, and the exhaust gas of a motor is guided to the lower rear direction of the vehicle. According to the improved truck silencer hanging device, the service life of parts such as the silencer can greatly be prolonged, the manufacturing is simple, the assembly and disassembly are convenient, and the improved truck silencer hanging device can be widely used for trucks.
Description
Technical field
The utility model relates to cargo vehicle manufacturing technology field, particularly a kind of improved cargo vehicle silencing apparatus erecting by overhang.
Background technique
The function of exhaust silencer is to reduce exhaust sound.Silencing apparatus, by reducing gradually the pulsation of exhaust pressure and decay exhaust pressure, dissipates totally exhaust energy.Silencing apparatus is generally formed by silencer air inlet pipe, front cover, muffler shell, inner noise elimination structure, rear end cover and muffler tail pipe assembly welding.Along with the progress of technology, the power of cargo vehicle motor progressively improves, the progressively raising that noise standard requires, and silencing apparatus size continues to increase, and silencing apparatus quality also continues to increase.The method that what at present cargo vehicle generally adopted pass through installs erecting by overhang on front end silencer air inlet pipe and rear end muffler tail pipe, in automobile using process, can cause silencer air inlet pipe and front cover and rear end cover and muffler tail pipe weld earlier period damage, greatly affect the working life of silencing apparatus.
Model utility content
The utility model proposes a kind of improved silencing apparatus erecting by overhang, it can overcome the problems referred to above.
This improved silencing apparatus erecting by overhang that the utility model provides, silencing apparatus front end airflow pipe inducer along the circumferential direction has four grooves, front exhaust pipe rear end is inserted in silencing apparatus front end silencer air inlet pipe and used outlet pipe clip connected, outlet pipe is bolt, nut clamping for clip, after fastening nut, be loaded on a same nut, prevent that nut from getting loose.The clamping force of bolt makes outlet pipe clip banding, has ensured the sealing between front exhaust pipe and silencing apparatus front end silencer air inlet pipe inducer.Two silencing apparatus clips are installed along external cylindrical surface in silencing apparatus stage casing, and silencing apparatus clip is made into the ring with opening with steel plate, in the plane that two limits that opening extends out form, are processed with bolt mounting holes.Silencer hanging bracket is with being bent into right angle after steel plate cutting, processing bolt mounting hole in the plane forming at two right angle sides respectively, use respectively bolt, nut by two silencing apparatus clip connecteds in two silencer hanging bracket lower ends, after fastening nut, be loaded on a same nut, prevent that nut from getting loose.After the upper buffer rubber gasket of two silencer hanging bracket upper end pads, be arranged on the left longeron lower aerofoil of vehicle frame with bolt, nut respectively, after fastening nut, be loaded on a same nut, prevent that nut from getting loose.Buffer rubber gasket can alleviate vibration greatly, extends the working life of outlet pipe and silencing apparatus.The lower rear of automobile is pointed in the muffler tail pipe outlet of silencing apparatus rear end, by the lead lower rear of automobile of engine exhaust.This improved silencing apparatus erecting by overhang can improve the working life of the parts such as silencing apparatus significantly, and makes simply, and easy accessibility, can be widely used in cargo vehicle.
