What are the differences between the 153 rear axle and the 457 axle?
3 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.
I've been driving in the trucking industry for over a decade and frequently work with 153 and 457 rear axles. The 153 rear axle is typically used in medium-duty trucks, like some older Dongfeng models, with a load capacity of around 8-10 tons, making it suitable for urban deliveries or short-haul freight. The 457 rear axle is used in heavy-duty trucks, offering stronger load capacity, easily handling over 15 tons, and is particularly suited for mountainous roads or long-distance transport. The differences are quite significant: the 153 is lighter and more compact, with simpler and more economical gear ratios; the 457 is much heavier, with a reinforced axle housing, sturdier gears, and a higher reduction ratio, providing more power when climbing hills. Having driven both, the 457 feels more stable on the road, but it doesn't accelerate as quickly as the 153. In terms of maintenance, the 153 requires frequent gear oil changes to prevent wear, while the 457 is more durable, allowing for slightly longer oil change intervals. Overall, the 153 is lower in cost and simpler to maintain, while the 457, though more expensive, is more reliable in the long run.
I'm a car enthusiast with in-depth knowledge of truck components. The 153 rear axle is a basic model used in light to medium-duty vehicles, featuring a relatively simple structure and a load capacity of around 10 tons. The 457 rear axle is an upgraded version designed for heavy-duty applications, capable of handling 15 tons or more. The main differences lie in size and efficiency: the 457 axle is larger, with an optimized gearbox offering a higher reduction ratio, which enhances climbing ability and fuel economy. I've test-driven a vehicle equipped with a 457 axle, and it delivers more power and stable braking. Additionally, the 457 uses better materials, making it less prone to overheating or damage. The 153 performs adequately on flat roads, but the 457 is better suited for rugged terrain. In terms of maintenance, the 457 requires higher-quality lubricants but has a longer lifespan. Overall, the 153 is more affordable and suitable for beginners, while the 457 is a professional choice for fleets.
