A DEEPER LOOK AT SPRING VS. AIR
Suspension systems contribute to a tractor-trailer’s road handling and ride quality (the vertical acceleration to which a tractor-trailer is exposed). Keeping the tires in contact with the road as much as possible, suspension systems help minimize the amount of jarring (bumps, vibrations) for improved load-carrying ability, protecting the trailer and the freight inside from being damaged.

With a variety of suspensions available on the market, spring and air ride are the most commonly used suspensions for heavy-vehicle applications such as tractor-trailers.

SPRING RIDE
Spring suspensions use semi-elliptic leaf springs to cushion a load from road shock. As one of the most commonly used suspensions, spring ride consists of several layers of flexible steel strips referred to as a “leaf pack.” The strips are joined together to act as a single unit. The long and narrow, arch-shaped plates are attached to the frame of a trailer, resting above the trailer's axle.

Air Ride
AIR RIDE
Air ride uses a variety of valves, air lines and air-spring bags in place of steel suspension. The flexible air-spring bags are made from a woven and rubber-like material. The air supplied to the air-ride suspension uses the same air compressor and air reservoir as a truck’s braking system. The supplied air pressurizes the air-spring bags, creating a spring-like motion that raises the chassis from the axle.

AIR-RIDE SUSPENSION FALLS SHORT IN TESTING
To ensure its fleet is outfitted with the best suspension system, Schneider ran an extensive series of tests between various air- and spring-ride suspension systems to compare the ride quality of the suspensions with three freight weights – 10,000, 30,000 and 40,000 pounds.

A series of vibration and acceleration trials were run using and comparing the values of ride smoothness and the maximum g-force (the maximum force transmitted) to determine ride quality.

Conducted with the load weights mentioned above, Schneider tested the industry standard spring suspension against four common air suspensions. The four air suspensions chosen represent the majority of suspensions in use today.

Air Ride VS Spring Ride
The tests consisted of:

Ride quality at the front of the trailer: The ride quality of the freight in the front of the trailer was examined and tests showed that the front ride quality was a function of the tractor suspension, not the trailer suspension, proving that the trailer suspension had little effect on the ride quality of the freight.
Ride quality at the rear of the trailer:The graph (right) shows the industry standard spring suspension compared with the average results of the four most popular air suspensions, proving that the average ride quality of the top four air suspensions is very close to the industry standard spring suspension. In fact, under most circumstances, the spring-ride suspension provided a better ride quality.Spring Ride Protects Freight and your Bottom Line
SPRING RIDE PROTECTS FREIGHT AND YOUR BOTTOM LINE
Some shippers view air ride as the top suspension choice for handling, lateral control and roll stability, and it's often said to be gentler on freight. On the other hand, spring ride has comparable damping characteristics (the control of motion or oscillation) to air ride for full loads. With limited light or less-than-truckload shipments, the perceived benefits of air ride are minimal at best.

These tests prove that both air- and spring-ride suspensions are capable of providing the proper damping levels needed not only to get the trailer back to a normal state in the least amount of time but also to protect the freight during transport.

Spring ride is less prone to maintenance issues during the lifecycle of a trailer when compared with air ride. Less likely to need replacement, spring ride has been known to last the life of a trailer. Air-ride suspension, on the other hand, is more likely to need replacement over the same life span, depending on the environment in which the unit resides. It is also more prone to failure – subject to puncturing, leaks and collapsing. Should an air-ride suspension collapse while out on the road, freight movement stalls, losing precious time and money.

The conclusion: Air-ride suspension is not superior to spring ride. Not only are air-ride suspensions more expensive to purchase and maintain, which could translate to inflated expense to the shipper, but more importantly, they do not guarantee superior ride quality.

Sayangi mobil anda!



Jika Anda memiliki SUV diesel, van, atau 4WD, kami harap Anda baca artikel ini ,karena apa yang akan kami katakan akan sangat mengejutkan. Tidaklah berlebihan untuk mengatakan bahwa ada risiko bahwa setiap tangki bahan bakar yang Anda masukkan ke kendaraan Anda membawa risiko kontaminasi air yang dapat menghancurkan seluruh sistem bahan bakar dan bahkan mesin dalam kilometer! Walaupun mengisi dari pertamnina bermerek/ minyak berkualitas Dan tidak terlalu sering bepergian - setiap kendaraan berisiko. Itulah mengapa sangat penting bahwa Anda memasang saringan tambahan solar tgs ke mobil anda

Jadi dari mana datangnya potensi kerusakan, dan mengapa Anda harus memasang tambahan saringan solar tgs kendaraan Anda? Masalahnya adalah dua kali lipat. Pertama, ada peningkatan jumlah kegagalan sistem bahan bakar yang disebabkan oleh air dalam diesel berkat tangki pertamina di seluruh negeri yang menua dan berkarat.





Jadi mengapa Anda tidak bisa mengandalkan filter bahan bakar pabrik Anda, terutama jika memiliki lampu peringatan untuk memberi tahu Anda ketika itu diisi dengan air? Masalahnya adalah saat lampu peringatan menyala, seringkali sudah terlambat. Pada tahap itu, ada peluang bagus bahwa air telah berhasil melewati filter bahan bakar pabrik Anda. Pada saat Anda berhenti di sisi jalan untuk menyelidiki, mungkin sudah terlambat dan kerusakan mungkin sudah dilakukan.

Untuk mobil diesel modren, injeksi commonrail adalah hal umum untuk mendapatkan HP dan torsi yg besar, cuma masalah terbesar dari mesin commonrail adalah kualitas dan kebersihan bahan bakar solar.

untuk mengatsi kualitas solar yg buruk , sangat disarankan memasang extra filter. pilihan extra filter juga ngak boleh sembarangan, harus sesuai sengan kapasitas mesin( Flow & Micron ). juga harus diperhatikan kualitas desain breket dan selang, yang mana breket dan selang sebaiknya tinggal pasang " plug and play "


- Satu-satunya Filter dengan 5 lapisan stratapore yg mampu menyaring emulsi ( air yg telah bercampur dengan solar )

- Satu-satunya Filter dengan 5 lapisan stratapore yg mampu menyaring emulsi ( air yg telah bercampur dengan solar )

- Extra Fuel Filter TGS memang didesain khusus untuk aplikasi sebagai Pre filter mesin kapasitas 8000cc – 500 hp

- Dgn Flow rate antara 90 GPH , tidak akan menyebabkan resistansi dari pemasangan extra fuel Filter ( untuk mesin 2500cc 170 HP Cuma membutuhkan 32 GPH )

- Stratapore memiliki daya serap kotoran yg besar & efisien ( 30 kali lebih besar dibanding saringan OEM biasa /cellulosa - capasitas hingga 72 gram ), sehingga bisa bertahan hingga pemakaian 30.000km

- Aplikasi pre filter tidak mencopot selang OEM & ukuran diameter selang tetap seperti OEM ( tidak terjadi hambatan di selang )

- Untuk aplikasi di mesin Tanpa Common rail, mengunakan FS1000 10 micron. pemasangan filter tambahan setelah filter utama OEM

- Untuk Aplikasi di mesin Common rail, mengunakan filter 10 micron absolut , pemasangan filter tambahan sebelum filter utama OEM

Wheels alignment report
Please see below email from our Local Sales Manager reporting the feedback to Kristian after one of our dealers install UCA001FA on his Hilux Revo ( he’s putting oversized tire too )

I’m not sure how important is wheel alignment in your market but it’s very important to do proper wheel alignment after raising the vehicle with suspension upgrade ( changing spring )
