Abstract
The invention relates to a device for determining the source of abnormal sound in a vehicle. The device comprises an electric motor, a transmission mechanism, an irregular roller, a jolting plate and a rubber block; the irregular roller or the jolting plate applies to wheels; and the jolting plate applies to the vehicle body through the rubber block in order to vibrate the vehicle body. By adopting the invention, the abnormal sound points can be determined quickly and accurately in a repair shop without a road test vehicle, and the effects of the treatment on the abnormal sound points can be examined in time. The invention can be widely applied to the industry of automobile maintenance.
Description
Technical field
The present invention relates to the auto repair technical field
Background technology
The car that loud, high-pitched sound makes a sound that creaks that drives everywhere can allow the people feels this car poor quality, vehicle condition is not good, car is very broken, drives and take enjoyment thereby reduced significantly.The technological means of handling this abnormal sound at present is: look for the highway section of one section uneven to carry out the road examination, in the process of road examination, seek and roughly determine to produce the position or the orientation of abnormal sound, again car is driven into the repair and maintenance shop parts that may have abnormal sound are opened and inspect, abnormal sound point is further determined.Yet this moment, abnormal sound disappeared because vehicle is in halted state, and the judgement of its abnormal sound point loses accuracy, often was difficult to judge, even can't judges, time-consuming dismounting usually makes problem can not get solving, and abnormal sound still exists.
Summary of the invention
In order to determine the abnormal sound source accurately, the invention discloses definite method in a kind of vehicle different sound source.This method need not just can accurately be determined its abnormal sound point with vehicle road examination in the repair and maintenance shop, and the treatment effect of energy real-time test abnormal sound, directly cause abnormal sound and got rid of fully, for the processing of abnormal sound problem provide one accurately, method fast and efficiently.
The technical solution adopted for the present invention to solve the technical problems is: change into the jolting plate that can pump through gear train by motor, or changing into the irregular roller of dead axle rotation through gear train by motor, described jolting plate acts on wheel or acts on car body through block rubber; Described irregular roller acts on wheel, and is provided with the stop motion mechanism that prevents that longitudinal direction of car from moving.Make vehicle produce vibrations, car body will be spacious in virtual connection, pine like this, the position of friction and interference sends abnormal sound.Even abnormal sound also can accurately find the abnormal sound point from below the covering in the process of dismounting, and the effect after can the processing of real-time test abnormal sound point.
The invention has the beneficial effects as follows: need not try on the road, the judgement of abnormal sound point is quick, accurate, and the effect after the processing of energy real-time test abnormal sound point.
