Reasons and Solutions of Abnormal Sound in Various Parts of Refrigerated Truck Body

  • Author:Chang Jie
  • Release on :2016-10-29

Refers to the abnormal sound believe that each refrigerated truck drivers will feel the same, for troubled himself for a long time the sound of submissive, but the refrigerated
owner is the most familiar with his car, the vehicle sounds and feel the most sensitive, so the best solution Own car problem is you. Refrigeration vehicle manufacturers today,
the school summary of the various parts of the body refrigerated abnormal sound causes and solutions for cold storage owners reference.

1, refrigerated truck body abnormal sound

This problem is usually due to the cold body stiffness is not enough, resulting in vehicle deformation in motion, the door and the car frame friction or jitter, or in some
places off the welding and the friction between the steel plate. In the doors and windows on the strip or rubbing rubber parts and other methods may be able to reduce or
eliminate abnormal sound, but a temporary solution.

2, the refrigerated truck engine board abnormal sound screw often move in the car often occurs displacement, if you hear the location of the grille as the "Para Para" abnormal
sound, in addition to the grid is really loose , Or refrigerated vehicle owners still have to check under the engine board screw is loose, or the engine guard and the film
loosening, resulting in abnormal sound, in addition to fastening screws, but also should be in the abnormal sound of some pads pad items, Can easily eliminate abnormal sound.

Some cars wind noise, and this shape, if confirmed that no increase in excess items, refrigerated truck owners do not even think of a way to solve their own. There are some car
parts of the cold body is not well fixed may also cause abnormal sound, generally tight on the screws can be resolved.

3, abnormal sound transmission

If the car in the transmission inside the "rustling" sound, and depresses the clutch and then disappear, then the source of the noise is a transmission failure, there may be
gearbox bearings or gear wear, bearing spots caused.

4, tire abnormal sound

Tire sound must be rhythmic, and the frequency of high-speed high. If it is a "pop" sound, mostly tire tread deformation, from the package, serious wear or air pressure; if it
is "blah" sound, it may be tread mixed with pebbles. If the tire whirring call to ring, and refrigerated body jitter and even the direction of significant deviation, needless to
say is definitely a tire burst, get off for a tire.
 
5, the engine compartment abnormal sound here more than the possibility of abnormal sound. Belt whistle more harsh, usually caused by the belt slip. If the engine is running in
the external metal parts of the sound of dry friction, usually generators, pumps, steering booster pump bearing damage performance.

Refrigerated truck engine running leak sound, it may be exhaust system clogging, vacuum tube leakage or fracture. Need to be reminded that if the engine is the abnormal sound,
refrigerated owners is mostly unsolvable, it is best to send factory maintenance.

6, suspended abnormal sound

A bumpy four wheels near the issue of "pound" or "Kacha" sound, mostly shock absorber problems or loose parts caused by suspension, be sure to double-check the regular repair
shop. Because the suspension parts not only with the comfort of the ride, but also the safety of refrigerated trucks, must not be overlooked.
