(1) "变矩器扫油泵"段
(2) "变矩器充油泵"段 (3) "停车制动器分离泵"段 (4) "变矩器扫油滤网"盖 | |
该泵有三段：
- "变矩器扫油泵"段 (1)
- "变矩器充油泵"段 (2)
- "停车制动器分离泵"段 (3)
泵由"变矩器"上的一个齿轮驱动。
"变矩器扫油泵"段 (1) 位于驱动端。 该泵段带走"变矩器"壳体底部的油。 这些油流经盖 (4) 后面的扫油滤网。 然后这些油流回液压油箱。
其它两个泵段从液压油箱获得机油。
"变矩器充油"段 (2) 将油输送到"变矩器充油滤清器"、"变矩器进口安全阀"和"变矩器"。
"停车制动器释放"段 (3) 将油输送到"停车制动器释放油滤清器"。 然后机油分流。 "停车和辅助制动器阀"接收部分机油。 该机油用于释放弹簧接合的停车制动器。 分流后的其余机油流入"锁定离合器"和"举倾机构控制阀"。 该机油用于接合"变矩器"中的"锁定离合器"。 输送到"举倾机构控制阀"的油被用作信号油。
