Abstract

A vehicle transmission having a valve body disposed adjacently to and in parallel with a side cover covering a front or rear side or a side surface of a transmission case in a vehicle width direction in a vehicle-mounted state, the side cover connected to the transmission case, in which an electromagnetic valve is included on the side cover side of the valve body, when viewed in a direction horizontal and parallel to mating surfaces of the transmission case and the side cover, a strainer for removing a foreign material in a hydraulic oil is disposed between the side cover and the valve body to overlap with at least a portion of the electromagnetic valve, and the strainer has an inflow portion for allowing the hydraulic oil to flow in disposed vertically above an oil surface.

First claim

The invention claimed is:

1. A vehicle transmission having a valve body disposed adjacently to and in parallel with a side cover covering a front or rear side or a side surface of a transmission case in a vehicle width direction in a vehicle-mounted state such that a longitudinal direction of the valve body extends along a vertical direction, the side cover connected to the transmission case, wherein
an electromagnetic valve is included on the side cover side of the valve body,
when viewed in a direction horizontal and parallel to mating surfaces of the transmission case and the side cover, a strainer for removing a foreign material in a hydraulic oil is disposed between the side cover and the valve body to overlap with at least a portion of the electromagnetic valve,
the strainer has an inflow portion for allowing the hydraulic oil to flow in disposed vertically above an oil surface, and
the hydraulic oil pumped by an oil pump is supplied to the inflow portion.

2. A vehicle transmission having a valve body disposed adjacently to and in parallel with a side cover covering a front or rear side or a side surface of a transmission case in a vehicle width direction in a vehicle-mounted state, the side cover connected to the transmission case, wherein
an electromagnetic valve is included on the side cover side of the valve body,
when viewed in a direction horizontal and parallel to mating surfaces of the transmission case and the side cover, a strainer for removing a foreign material in a hydraulic oil is disposed between the side cover and the valve body to overlap with at least a portion of the electromagnetic valve,
the strainer has an inflow portion for allowing the hydraulic oil to flow in disposed vertically above an oil surface,
the hydraulic oil pumped by an oil pump is supplied to the inflow portion,
a first space is formed between the side cover and the strainer,
a filter for filtering is disposed in the first space,
the strainer has an outflow portion disposed vertically under the oil surface,
the hydraulic oil flowing into the first space from the inflow portion passes through the filter and flows out from the outflow portion, and
the hydraulic oil flowing out from the outflow portion is supplied through the valve body to a lubrication required portion.

3. The vehicle transmission according to claim 2 , wherein
the filter is disposed in the vertical direction, and
the first space is divided into two spaces by disposing the filter in the vertical direction.

4. A vehicle transmission having a valve body disposed adjacently to and in parallel with a side cover covering a front or rear side or a side surface of a transmission case in a vehicle width direction in a vehicle-mounted state, the side cover connected to the transmission case, wherein
an electromagnetic valve is included on the side cover side of the valve body,
when viewed in a direction horizontal and parallel to mating surfaces of the transmission case and the side cover, a strainer for removing a foreign material in a hydraulic oil is disposed between the side cover and the valve body to overlap with at least a portion of the electromagnetic valve,
the strainer has an inflow portion for allowing the hydraulic oil to flow in disposed vertically above an oil surface,
the hydraulic oil pumped by an oil pump is supplied to the inflow portion,
a first space is formed between the side cover and the strainer,
a filter for filtering is disposed in the first space,
at least one oil outflow hole is formed at positions lower than the inflow portion in the vertical direction of the strainer,
the hydraulic oil flowing into the first space from the inflow portion passes through the filter and flows out from the oil outflow hole, and
the hydraulic oil flowing out from the oil outflow hole is discharged to a second space on the transmission case side.

5. The vehicle transmission according to claim 4 , wherein
the filter is disposed in the vertical direction, and
the first space is divided into two spaces by disposing the filter in the vertical direction.
