How to ensure the quality of maintenance of electric transaxle of cleaning vehicle?
As the core power transmission system of cleaning vehicle, electric transaxle plays a vital role in the performance, efficiency and life of the vehicle. In order to ensure the quality of its maintenance, so as to ensure the normal operation of cleaning vehicle and extend its service life, the following will be elaborated in detail from multiple aspects.

1. Basic maintenance points of electric transaxle of cleaning vehicle

(i) Regular inspection of motor brushes

Motor brushes are one of the key components affecting the performance of electric transaxle. About 70% of motor failures are related to worn brushes. Therefore, it is necessary to check the wear of brushes every six months. If the brushes are severely worn, it will cause unstable operation of the motor or even damage, which will affect the normal operation of the entire transaxle. Regular inspection can timely detect brush problems, replace them in advance, and avoid potential expensive repair costs.

(ii) Lubrication
Lubrication is essential for the performance of electric transaxle. It is recommended to use synthetic oil for lubrication every 200 working hours to reduce friction and improve efficiency. Good lubrication can extend the service life of transaxle and keep it in good performance for more than 3000 working hours. During the lubrication process, make sure to use the appropriate lubricant and follow the correct lubrication method to avoid component damage caused by improper lubrication.
(III) Temperature range control
Extreme temperatures can have an adverse effect on the internal components of the electric transaxle. Therefore, it is recommended to operate these devices within a safe temperature range of -20°C to 40°C to prevent startup and performance problems. In high temperature environments, the viscosity of the oil will decrease, which may lead to insufficient lubrication and increased component wear; while in low temperature environments, seals may become brittle and easily break, causing oil leakage and other problems. Therefore, try to avoid using the cleaning car in an environment outside the recommended temperature range, or take appropriate temperature adjustment measures.
(IV) Tighten the connection
Loose connections can cause power loss and affect equipment performance. Check and tighten the connections regularly to maintain a stable current flow and prevent performance degradation.
