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. |
