Improvement

The torque converter is easy to heat up

 Inability to climb hills

Climbing long slopes is prone to overheating

 Punch

Easy to burn the friction plate

 Loud noise

Cause Analysis

 Small horse-drawn cart

 The hydraulic flow of the charging oil is low and the pressure fluctuates greatly

Comparison with Top Euro brand 

Customized design to solve customer pain points

 Short lead time, 3 months

Electrically controlled shifting and automatic shifting mode are adopted to reduce shifting impact and protect gears from damage

Hydraulic torque converter has large circulation, large transmitted torque, large traction and strong climbing ability. Change

Torque is not easy to heat up.

 The clutch structure is improved to reduce the friction plate burning phenomenon caused by the inaccurate control of the engagement time of the two clutches during the shifting process.

 The gear is thickened to improve the reliability of the gearbox. Higher reliability and longer life.
