CZJB differential creating the core power system of E-TRIKE
With the rapid development of green travel and terminal logistics, electric tricycles (E-TRIKEs) are becoming an essential tool for urban distribution and short-distance transportation in overseas markets. Faced with complex road conditions and high load demands, E-TRIKEs place higher demands on their powertrains: they must deliver powerful power while maintaining a smooth ride. CZJB’s independently developed differential, combined with a high-performance motor, is the ideal solution to this demand.
1. The Importance of Differentials:
Turning is essential for electric tricycles. Without a rear differential, both wheels would rotate at the same speed during turns, causing tire drag, increased wear, and even affecting vehicle handling. A differential automatically adjusts wheel speed during turns, ensuring stability, steering flexibility, and improved safety.
2. Two types of CZJB differentials to meet different needs
(1) Aluminum alloy differential – Lightweight and flexible, suitable for carrying passengers
Lightweight Design: Aluminum alloy reduces vehicle weight and improves fuel efficiency.
Preferred for narrow-tire bikes: Ideal for urban commuting and family travel.
Comfort: Smoother power delivery delivers a smoother ride.
(2) Iron differential – strong and durable, designed for pulling goods
High-strength construction: Durable, wear-resistant steel casing.
Strong load-bearing capacity: Loads up to 800kg, ensuring stress-free transportation.
A great logistics helper: Suitable for complex road conditions and heavy loads.
3. Advantages of the CZJB differential
(1) More stable single-speed sprocket mounting method
Three positioning grooves are added to CZJB differential disc brake surface, which, when combined with the matching sprocket, allows for quick positioning during assembly. At the same time, the force points when the sprocket rotates are increased from six screw positions to nine, thereby improving the fixing strength of the sprocket.
(2) The bearings at the spline can bear higher strength loads
CZJB differential uses oil-containing bearings made through powder metallurgy technology, which can withstand greater loads and are less prone to damage.
(3) Stronger bonding strength
CZJB differential is divided into three parts, and 6 M4 screws are used to fasten each end to greatly improve the bonding strength.
(4) Stronger bonding strength
CZJB differential is composed of three parts, featuring flexible structural switching and low cost, making it easier to achieve customization of non-standard products.
(5) Higher impact strength
CZJB differential uses 60Si2Mn spring washers at both ends of the pinion, which are wear-resistant and can withstand large load impacts.
