快速充油液压换挡系统
摘要：
一种快速充油液压换挡系统，主要包括快速充油油路和缓冲升压油路。所述快速充油油路由二位二通电磁阀、单向阀组成。所述缓冲升压油路的进油口与主油路连通，出油口与换挡离合器油缸连通。所述二位二通电磁阀进油口与主油路连通，出油口与单向阀的进油端连通，单向阀的出油端与换挡离合器油缸连通。本实用新型将主油路分为快速充油油路和缓冲升压油路，换挡初期，先通过快速充油油路对换挡离合器油缸充油，使液压油以更快的速度充入换挡离合器油缸，有效缩短换挡时间。
摘要（英）：

The utility model provides a fast oil filling hydraulic gear shifting system, which mainly comprises a fast oil filling oil path and a buffer pressure boosting oil path, wherein the fast oil filling oil path consists of a two-position two-way electromagnetic valve and a one-way valve, an oil inlet of the buffer pressure boosting oil path is communicated with a main oil path, an oil outlet of the buffer pressure boosting oil path is communicated with a gear shifting clutch oil cylinder, an oil inlet of the two-position two-way electromagnetic valve is communicated with the main oil path, an oil outlet of the two-position two-way electromagnetic valve is communicated with the oil inlet end of the one-way valve, and the oil outlet end of the one-way valve is communicated with the gear shifting clutch oil cylinder. The fast oil filling hydraulic gear shifting system has the advantages that the main oil path is divided into the fast oil filling oil path and the buffer pressure boosting oil path, and in the early gear shifting stage, the gear shifting clutch oil cylinder is firstly filled with oil through the fast oil filling oil path, so that the hydraulic oil is filled into the gear shifting clutch oil cylinder at a higher speed, and the gear shifting time is effectively shortened.
