Sinotruk az9725160390 Clutch disc

Product representation

1 、 Model and specification

Common models: such as WG9921161100, WG9925160300, WG1560161130, WG9921160800/1 and so on.

The size of the platform: 430 mm and other different specifications can be adapted to various capacities and models of heavy trucks.

2, structural composition

The clutch case: usually made of high -strength metal materials, such as high -quality steel or aluminum alloy, etc., with high strength and rigidity that can withstand various forces and pressure in the transmission process, in order to ensure normal clutch operation.

Friction disk

Material: usually used asbestos material containing copper wire, ceramic -based material or half -metal material. These materials have good wear resistance, resistance to high temperatures and stability of the friction coefficient, and can withstand friction losses with frequent adhesion and transmission of high torque.

Quantity: Odino and two -disc constructions are usually found, for example, the WG9921160800/1 model with 2 friction surfaces.

The hub of the driven disk: this is a part connecting the case of the driven disk and the input shaft of the transmission, and usually uses the slotted connection method. The size and shape of the slice are carefully developed, and the accuracy of the conjugation with the input shaft of the transmission is high to ensure high efficiency and accuracy of power transmission, as well as reduce power loss and transmission noise.

A shock -absorbing spring: a three -stage design of a shock -absorbing spring can effectively reduce the abnormal shaking of the car at idle and make the car more smoothly, and can also better soften the exposure to the transmission and protect other parts of the transmission system during the launch of the car and gear shifts.

3 product characteristics

Fraud coefficient: usually about 0.4, for example, in the clutch disc WG9921160800/1 of the Yuanlong brand, the friction coefficient is 0.44, which can provide sufficient friction for reliable power transmission.

Nominal static torque: nominal static torque varies from model to model, for example, the nominal static torque of a certain product can reach 3,000, which can satisfy the requirements for the transmission of the torque of the heavy trucks in various operating conditions.

Twisting at idle: less torque at idle can reduce the loss of energy of the coupling in the off state and increase the effectiveness of the transmission.

4 、 applicable models

It is mainly used for many heavy trucks of the Howo brand, such as Howo T7H, Howo T5G, Howo Han, Shanteka C7H, etc. At the same time, it can be adapted to some heavy trucks of other brands, such as Hongyan, Shaanchao Delong, Ouman and Jiangjiang.

5 、 Production process

High -precision processing: In the process of grip production for heavy Howo heavy trucks, advanced equipment and processing processes are used to ensure the accuracy of processing of each component, for example, the flatness of the friction discs, the accuracy of the size of the helmet, etc., to ensure the stability of the quality and productivity of products.

Strict quality control: through a strict quality control system, disc indicators are checked, such as friction coefficient, torque transmission power, vibrational extinguishing, etc., to make sure that each product meets high quality standards and can satisfy high intensity requirements heavy trucks.

6 、 appearance and packaging

Appearance: the surface is usually finely treated, without obvious defects, scratches or deformations, with a uniform coating and a homogeneous color to ensure good quality of appearance and anti -corrosion characteristics.

Packaging: Independent packaging is usually used, such as cardboard or plastic packaging, to prevent damage during transportation and storage, some products will also have moisture, impact and other protective measures

In addition to the above slipping, abnormal noise, incomplete separation and trembling at the start, the following common malfunctions of the clutch disks Sinotruk:

Clutch malfunction

Heavy pedal: a squeezing bearing, a squeezing fork and other parts in the working mechanism of clutch can be poorly lubricated, strongly worn or stuck. The force of the clutch pressing spring can be too large. Also in the hydraulic working system there may be air or dirty oil or clogged tubes.

The pedal does not have a free stroke or the free move is too small: the squeezed bearing will be constantly pressed to the turn off the turn off, which will not turn on and will slip. The cause may be an incorrectly adjusted clutch cable, a faulty hydraulic system or a problem with the pedal mechanism itself.

Poor return of the pedal: after the driver releases the pedal, the pedal cannot return to the starting position in time. The return spring of the pedal can be worn out, broken or fell off, and the pedal shaft or connected connecting parts can rust or get stuck.

Burning out the friction disk: frequent work with half -pushed clutch, prolonged work in high load conditions or poor heat discharge from clutch leads to the fact that the heat released during the friction of the clutch disc becomes too high, which leads to the burnout of the friction disk. The surface of the friction plate after ablation will become black and solid, and the friction coefficient will decrease, which will affect the transmission of power and cause slippage.

The wear of the slotted disk: the slots of the driven disk interact with the slots of the first transmission shaft for a long time, which can lead to wear. Wear leads to a weakening of the landing of the driven disk on the slotted shaft, which leads to blows and shaking when transmitting power, as well as to the emergence of an abnormal noise during movement.

Clutch vibration: when the car starts from the place or shifts the transmission, in the process of turning on the clutch, obvious vibration is felt. The clutch pressing disc, the flywheel or the driven disk may have uneven wear or surface deformation, or the compression spring may have uneven elasticity, or individual springs can be damaged, which leads to uneven force on the adhesion disk when it is turned on.

Sinotruk clutch policy

Warranty service

Warranty period: as a rule, the warranty period for the Cinotes of SinoTRUK, as on the wear -out part, can be six months or about 10,000 kilometers. However, there may be differences between different models and series, and the warranty period for the clutch disk of some models can be slightly or less.

Warranty volume: during the warranty period, if the clutch disc is out of order due to inhuman factors, such as problems with the quality of the material, defects of the production process, such as cracks, falling, breakdown of the spring disc spring, etc., Sinotruk will provide free Repair or replacement services. However, if the damage is caused by the incorrect actions of the driver, such as the long half -pushed clutch, the frequent sharp operation of the clutch, overload, which causes excessive wear of the clutch disc, and other human factors, then the guarantee, as a rule, does not apply.
