What are the differences between the 153 rear axle and the 457 axle?
1 Answers
The specific differences between the 153 rear axle and the 457 axle are as follows: 1. Bearings: The 457 axle has enlarged bearings, but its load capacity remains the same as the 153. According to parameters, the 153 is a Dongfeng 10-ton axle, while the 457 is a 13-ton axle, and the 457 definitely has a stronger load-bearing capacity than the 153. The 435 axle is a 10-ton axle with eight half-shaft bolts and six drive shaft threads, whereas the 457 axle is a 13-ton axle with ten half-shaft bolts and eight drive shaft threads. 2. Diameter: For the 457, this number indicates that the pitch circle diameter of its driven gear is 457mm, 485mm, or 498mm, with varying output torque—the 457 can reach 45,000 N·M. In fact, there are many factors that affect load-bearing capacity, including the main and driven gears, axle housing, half-shafts (for example, single-stage axles are prone to breaking, so engineering vehicles generally use Steyr and Mercedes wheel-reduction axles), etc. (Heavy loads also involve components like brakes.) The 153 axle, with a driven gear pitch circle diameter of 435mm, was originally introduced by Dongfeng using Nissan Diesel technology, with a 5T front axle and a 10T rear axle, installed on Dongfeng's original 153 model, hence the name 153 axle.
