Ról patrún na mbonn

2021-07-02

I mbeagán focal, is é príomhfheidhm anbonnis é an patrún ná an frithchuimilt idir an tread agus dromchla an bhóthair a mhéadú chun an roth a chosc ó sleamhnú, atá mar an gcéanna leis an bpatrún aonair.

Tá anbonnfeabhsaíonn patrún leaisteachas teagmhála talún an tread. Faoi ghníomh an fhórsa inláimhsithe (amhail fórsa tiomána, fórsa coscánaithe agus fórsa cliathánach) idir an tread agus dromchla an bhóthair, is féidir leis an mbloc patrún dífhoirmiú leaisteach inláimhsithe níos mó a dhéanamh. De réir mar a mhéadaíonn an fórsa tadhlaíoch, méadaíonn an dífhoirmiú inláimhsithe, agus méadaíonn “éifeacht cuimilte” an dromchla teagmhála freisin, rud a chuireann cosc ​​ar an tread sleamhnú nó sleamhnú ar dhromchla an bhóthair. Cuireann sé seo deireadh den chuid is mó le heasnaimh neamhphhatrún (tread éadrom)boinnthat are easy to slip, making the car performance related to the friction between the bonnand the road surface-dynamic, braking, steering and driving safety There is a reliable guarantee for normal performance. Studies have shown that the factors that produce the friction between the tread and the road surface also include the adhesion between the two sides, the molecular gravitational effect, and the new micro-cutting effect of the pavement's small rain on the surface of the tread. However, its main role is What is still the elastic deformation of the pattern block.
