Abstract
A vertical silencer mounting structure for a heavy truck comprises a portal frame, a truck frame, an exhaust pipe, a vertical silencer and a silencer support which are all mounted on the rear side of a cab. The mounting structure is characterized in that the silencer support is composed of a first supporting rod, a second supporting rod and an L-shaped bracket, the vertical section of the L-shaped bracket is connected with the outer side of the truck frame, the exhaust pipe stretches to the lower side of the horizontal section of the L-shaped bracket, the vertical silencer is arranged on the upper side of the horizontal section of the L-shaped bracket, an air outlet of the exhaust pipe is connected with the lower end of the vertical silencer, one end of the first supporting rod is connected with the upper portion of the vertical silencer, the other end of the first supporting rod is connected with the portal frame, one end of the second supporting rod is connected with the middle of the vertical silencer, and the other end of the second supporting rod is connected with the portal frame. The vertical silencer mounting structure has the advantages of being simple in structure and suitable for modifying the heavy truck with a transverse silencer to reduce raise dust.
Description
Technical field
The utility model relates to a kind of heavy duty truck, relates in particular to the vertical muffler installation structure of a kind of heavy duty truck.
Background technology
Compare serious area in desertification, because ground dirt is more, if with the noise silencer lateral arrangement under the heavy duty truck chassis, airborne dust is big in the time of can causing travelling, influence the sight line of other vehicles, therefore, must put noise silencer is perpendicular at some area (as Ecuador) mandatory requirement heavy duty truck, make upwards discharging of tail gas.
The utility model content
At the problem in the background technology, the utility model proposes the vertical muffler installation structure of a kind of heavy duty truck, comprise portal frame, vehicle frame, freeing pipe, vertical noise silencer and the silencer support of operator's compartment rear side, its improvement is: described silencer support is made up of first strut bar, second strut bar and L shaped carriage; The vertical section of L shaped carriage is connected with the vehicle frame outside, and freeing pipe extends to the horizontal segment downside of L shaped carriage, and vertical noise silencer is arranged at the horizontal segment upside of L shaped carriage, and the air extractor duct of freeing pipe is connected with vertical noise silencer lower end; First strut bar, one end is connected with vertical noise silencer top, and the first strut bar other end is connected with portal frame, and second strut bar, one end is connected with vertical noise silencer middle part, and the second strut bar other end is connected with portal frame.
Structure of the present utility model is very simple, is particularly suitable for the upgrading to the vehicle of noise silencer horizontally set.
In order to shorten the length of freeing pipe, the utility model has also been done following improvement: the horizontal segment of L shaped carriage is positioned at the vehicle frame outside.
Based on aforementioned schemes, in order further to improve the stability of vertical noise silencer, avoid vertical noise silencer play, the utility model has also been done following improvement: described first strut bar and second strut bar are curved bar, the junction of first strut bar and vertical noise silencer is positioned at the vehicle frame outside, and the junction of first strut bar and portal frame is positioned at the vehicle frame inboard; The junction of second strut bar and vertical noise silencer is positioned at the vehicle frame outside, and the junction of second strut bar and portal frame is positioned at the vehicle frame outside.
In order further to improve the structural stability between L shaped carriage and the vehicle frame, the utility model has also been done following improvement: the vertical section of L shaped carriage extends to the vehicle frame top, is provided with reinforced rib between vertical section and the vehicle frame upper side.
In order to reduce the vibration of freeing pipe, guarantee the connective stability between freeing pipe and the vertical noise silencer, the utility model has also been done following improvement: the horizontal segment downside of L shaped carriage is provided with garter spring, and exhaust shroud is connected in the garter spring.
Useful technique effect of the present utility model is: simple in structure, be suitable for the repacking to the heavy duty truck of noise silencer horizontally set, to reduce airborne dust.
