Howo High quality Input Shaft WG2210020105

Description

The function introduction of the Input Shaft WG2210020105 of SINOTRUK HOWO and STEYR:

Howo input shaft WG2210020105 function:

Just like a “matchmaker”, it transmits the power generated by the engine to the gearbox, enabling the vehicle to achieve different speeds and power outputs, and ensuring the normal operation of the vehicle.

HOWO input shaft WG2210020105 structural design:

HW18710 Transmission: The main gearbox adopts a double-pin shaft structure, with the two pin shafts arranged 180° apart. The auxiliary gearbox uses a planetary reduction mechanism. After the power is input from the input shaft, it is divided into two pin shafts, then gathered to the main shaft, and finally output through the planetary reduction mechanism of the auxiliary gearbox. This can reduce the center distance and gear thickness of the transmission, shorten the axial length, and lighten the weight.

Main shaft floating structure: To ensure correct meshing and load distribution evenly, the main shaft adopts a hinged floating structure, eliminating the traditional needle roller bearings. This makes the main shaft assembly structure simpler. Moreover, the main shaft only bears torque and does not bear bending moments, thereby improving the force conditions of the main shaft and bearings, and enhancing the reliability and lifespan of the transmission.

Common models of the Howo input shaft:

AZ2203020105: Haowuo Heavy Truck Transmission Input Shaft and One-Axis Gear Assembly, suitable for some Haowuo models.
WG2210020105: Suitable for Haowuo Heavy Truck Wanhai models, also compatible with Shandaka models.
AZ9970320113: Haowuo Heavy Truck 70 Mining Vehicle Input Shaft Assembly.
AZ2203020249: Haowuo Heavy Truck T7H, Shandaka C7H, Haohan Input Shaft and One-Axis Gear Assembly (Overdrive, Helical Teeth, Short Input Shaft).

Howo input shaft WG2210020105 malfunction and its causes:

Gear wear: Frequent and intense driving over an extended period, or failure to maintain the vehicle on time, can cause the gears in the input shaft assembly to wear out, resulting in reduced vehicle power, poor shifting performance, and abnormal noises.

Bearings issue: Poor bearing quality or lack of lubrication will cause damage to the bearings of the input shaft assembly, resulting in noise and affecting the efficiency of power transmission.
Improper assembly: Incomplete or incorrect operation during maintenance or assembly, as well as unskilled workers, will lead to improper assembly of the input shaft assembly, causing abnormal noises during vehicle operation and even affecting normal gear shifting.

Other reasons: The aging of the oil seal in the input shaft assembly can lead to oil leakage, affecting lubrication and sealing performance; Insufficient or poor quality transmission oil will increase the friction between components, causing overheating and wear, which can result in faults in the input shaft.

The Hovua input shaft WG2210020105 is a key transmission component within the gearbox. Its maintenance cycle is not independently set but is closely linked to the overall maintenance of the gearbox. Maintenance is mainly achieved through the replacement cycle of the gearbox oil and regular inspections. The following are the specific maintenance cycles and related suggestions:

1. Basic Maintenance Cycle (Based on Transmission Oil Replacement)
The lubrication and protection of the Havo input shaft rely on the transmission oil. Therefore, the replacement cycle of the transmission oil directly determines the maintenance frequency of the input shaft. The specific cycle varies depending on the vehicle model and usage scenario:

Regular road transport vehicle models (such as Haowo T7H, HOWO-7, etc.):
It is recommended to change the transmission oil every 60,000 – 80,000 kilometers. During the replacement, the wear conditions of the input shaft-related components (such as gears, bearings) will be checked to ensure proper lubrication and reduce frictional losses of the input shaft.
Heavy-duty / harsh working condition vehicles (such as mining Haowo 70 mining trucks, engineering vehicles):

Due to the heavy load and complex driving environment, the transmission oil deteriorates faster. It is recommended to replace it every 30,000 – 50,000 kilometers, and shorten the inspection cycle to avoid abnormal wear of the input shaft due to insufficient lubrication.
