Product Description

Product Introduction

It consists of a transmission shaft with a central support and a transmission shaft with a sliding joint. The two shafts are connected by a Hooke-type universal joint in the middle. This assembly can transmit torque and compensate for changes in the position and angle of the transmission and rear axle during vehicle motion.

 

Technical Parameters

1. The assembly’s yield torque ≥ 44,000 N·m 
2. Rotational speed: 2500 rpm; residual unbalance ≤ 80 g·cm. 
3. Torsional Fatigue Endurance Requirement: Under the rated load torque, the median life shall be ≥200,000 cycles; evaluation torque: 22,000 N·m. 
4. Universal joint durability requirements: Under installation angles of 7 degrees, the universal joint must withstand the evaluation torque and number of cycles specified below: Evaluation torque: 14,300 N·m; Number of cycles: 2,000,000.

 

Product Advantages

A lightweight, high-precision shaft tube is employed, with the drive shaft runout as low as 0.6 mm and dynamic balance reaching G16 standards. Shock-absorbing paper is installed inside the shaft tube, effectively reducing drive shaft noise.

 

Product Use

The medium- and heavy-duty propeller shaft, used in medium- and heavy-duty trucks, transmits power from the transmission to the rear axle. Typically, it consists of a propeller shaft with an intermediate support combined with a propeller shaft equipped with a sliding joint.
