Fungsi Lower Arm

Fungsi Lower Arm

Tahukah anda ‘lower arm’ adalah komponen kenderaan yang tergolong dalam kategori suspension system. Ianya berada dalam kategori yang sama bersama-sama dengan tayar, shock absorber, spring dan linkages.

Ia  berfungsi sebagai pemegang tayar kepada kerangka kereta dan bushing untuk memastikan tayar dalam keadaan betul serta mengekalkan keupayaan stabil pembelokan kiri dan kanan.

Model dan bentuk lower arm ini juga bermacam-macam bergantung dari rekaan dan jenis suspensi yang digunakan, seperti contohnya untuk suspensi double wishbone, umumnya lower arm memiliki model dan bentuk seperti huruf A.

Bagi suspense jenis Macpherson biasanya menggunakan lower arm yang berbentuk seperti huruf L. Selain daripada itu, bagi model suspensi lain, lower arm terdapat juga dalam bentuk huruf A dan I . 

Perhatikan pada model lower arm dibawah ini :

jenis lower arm


Fungsi utama lower arm :
a) Menyambung bahagian knuckle, iaitu merupakan komponen tempat dimana roda (ban dan velg) dipasang berikut dengan hub dan komponen rem.
b) Mengawal pergerakan roda bergerak ke atas dan ke bawah serta maju dan mundur akibat efek gerak dari pengemudian akan dibatasi gerakannya oleh lower arm ini.
c) Memastikan kedua roda depan atau belakang dapat membelok dengan kadar sama.

FEP Drive Shaft

FEP Drive Shaft


The function of the FEP drive shaft is to transfer the engine torque from the gearbox or differential to the wheels. It must also compensate for all variations in angle or length resulting from manoeuvring and deflection for perfect synchronisation between joints.

fep-drive-shaft

Drive shafts for cars with front wheel drive consist of the outboard fixed joint, the inboard constant velocity joint and the connecting shaft. They also include elements such as the anti-lock system ring and the torsion damper.

In most cases the inboard CVJ takes the form of a slip joint to allow the drive shaft to follow the movements of the wheel suspension. At the front axle (leading axle) the outboard joint must transfer the torque effectively through a large angle (up to 52 degrees). At the rear axle the angles of the outboard joints are considerably smaller.


Safety
Drive shafts and constant velocity joints are components of modern cars, which demand maximum safety.

Most problems with the drive shaft manifest themselves in the form of knocking noises when driving round tight corners, accelerating, or when the suspension is being compressed and extended. To avoid putting the safety of the vehicle at risk, make an appointment with a specialist garage if any of these symptoms occur. Specialists can be relied upon to detect damage to the drive shaft and provide the necessary assistance in good time.

CAUSES OF DAMAGE
Wear over time is one of the most frequent causes of damage to outboard and inboard joints. Damage can also be caused by faulty sleeves, by use of low-quality grease and in many cases by not following the correct procedures for installation and removal. 

SYMPTOMS OF DAMAGE
Most problems with the drive shaft manifest themselves in the form of

  • knocking noises when driving round tight corners
  • accelerating or 
  • when the suspension is being compressed and extended.


To avoid putting the safety of the vehicle at risk, make an appointment with a specialist garage if any of these symptoms occur. Specialists can be relied upon to detect damage to the drive shaft and provide the necessary assistance in good time.
