| 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. |
