Rear Differential Assembly for Dongfeng EQ145

This rear differential assembly is for Dongfeng EQ145 application enquiries. The axle identification and gear configuration determine the matching assembly.

Compare the crown-wheel and pinion tooth counts, axle-shaft splines, mounting pattern and input flange. Include the axle plate and original assembly photographs when requesting a replacement.

Send the vehicle and axle identification, crown-wheel and pinion tooth counts, spline details and quantity. Include the flange and housing dimensions for the assembly required.

The rear differential assembly for the Dongfeng EQ145 is the final-drive component of the truck’s rear axle, the point where the driveline makes its last speed reduction before torque reaches the wheels. Drive enters through the input flange, passes from the pinion to the crown wheel, and leaves through the side gears toward the two axle shafts, and those side gears allow the shafts to rotate at different speeds when the truck corners so the outer rear wheel covers more ground than the inner one without forcing either tyre to slip. The assembly works under continuous load in a goods-carrying application, which is why the gear pair and its carrier are supplied as one exchange unit rather than as loose components.

• Component: rear differential assembly for the Dongfeng EQ145 rear axle
• Vehicle application: Dongfeng EQ145 truck
• Position in the driveline: final reduction stage between the propeller shaft and the axle shafts
• Working parts: input flange, pinion and crown wheel, side gears

The rear differential assembly for the Dongfeng EQ145 is matched to the truck through the axle plate and the physical measurements of the original unit, not through a ratio printed on this page. Dongfeng identifies its rear axles by plate and stamping, and those two sources are the reference for a correct order. A workshop compares the crown-wheel and pinion tooth counts of the removed unit, counts the axle-shaft splines and measures the mounting pattern and the input flange, then passes the figures with the enquiry. Photographs of the axle plate and the old assembly give TOSEN the same view the workshop has, which is why they are requested at quotation stage.

• Reference sources: the axle plate and the markings on the removed assembly
• Measurements to take: crown-wheel and pinion tooth counts, axle-shaft splines, mounting pattern, input flange
• Supporting evidence: photographs of the axle plate and the original assembly
• Selection rule: match the physical axle, not the truck name alone

Each rear differential assembly for the Dongfeng EQ145 leaves TOSEN as a new, inspected component matched to the axle details in the enquiry. The inspection covers the tooth counts, the axle-shaft splines and the flange and mounting dimensions, so the unit that ships matches the axle described in the order. Where the enquiry includes photographs, they become the reference for the check, which reduces the chance of a mismatch between the shipped unit and the axle on the truck. Fleets running several EQ145 vehicles can send the details of every truck in one list and receive assemblies matched vehicle by vehicle.

What is the rear differential assembly for the Dongfeng EQ145?

The rear differential assembly for the Dongfeng EQ145 is the final-drive unit of the truck’s rear axle, containing the pinion, the crown wheel and the side gears in one assembled component. Drive from the propeller shaft enters at the input flange, is reduced and redirected by the gear pair, and is divided between the two rear axle shafts, which can rotate at different speeds when the truck turns. The unit replaces the original part as a complete assembly.

How is the correct EQ145 differential identified?

Identification starts with the axle plate and the markings on the assembly being replaced. Count the crown-wheel and pinion teeth, count the axle-shaft splines, and measure the mounting pattern and the input flange, then send those figures with photographs of both the plate and the removed unit. TOSEN uses that information to match the order to the physical axle on the EQ145 rather than to the model name alone.

Why are photographs requested with an EQ145 differential enquiry?

Photographs show the axle plate stamping, the shape of the input flange and the layout of the mounting surface exactly as they appear on the truck, and written descriptions can miss details that a picture preserves. An EQ145 that has spent years in fleet service may not match every published description of the model, so pictures of the actual axle let the enquiry be checked against the vehicle in front of the workshop.

What should an EQ145 differential enquiry contain?

State the truck model and the axle plate details, the tooth counts of the crown wheel and pinion, the axle-shaft spline count, the flange and mounting dimensions, the quantity required and the destination. Attach photographs of the axle plate and the original assembly, and TOSEN will match the enquiry to the correct rear differential assembly before quoting.
