Hydraulic component mounting assembly with anti-rotation poka-yoke banjo connection

A hydraulic component mounting assembly comprising:

• a hydraulic component having a port and including a surface, wherein the surface includes a first mounting hole configured to receive a stopping fastener, wherein the stopping fastener protrudes from the surface by a first distance when the stopping fastener is inserted into the first mounting hole;
• and
• an anti-rotation banjo connection comprising
• a banjo plate attached to a pipe at a first end edge of the banjo plate, the banjo plate including an opening configured to receive a bolt;
• wherein the banjo plate further includes a hollow portion in fluid communication with the pipe and extending along a fluid flow axis of the banjo plate from the first end edge to the opening at which the banjo plate is provided with a transverse aperture configured to access the hollow portion;
• wherein the bolt is configured to be screwed into the port of a hydraulic component;
• whereby the port is in fluid communication with the pipe by a fluid path offered by the bolt and the hollow portion when the bolt is screwed into the port;
• wherein a second end edge of the banjo plate, opposite to the first end edge, is provided with a positioning notch configured to partially surround a stopping fastener when the bolt is screwed into the port and the stopping fastener is inserted into the first mounting hole of a surface of the hydraulic component so as to protrude from the surface by a first distance longer than a plate distance by which the banjo plate is spaced apart from the surface when the bolt is screwed into the port;
• whereby an edge wall delimiting the positioning notch is configured to interfere with the stopping fastener preventing the banjo plate from rotating about the bolt when the stopping fastener is inserted into the first mounting hole and the bolt is screwed into the port;
• whereby the bolt is screwed into the port when the stopping fastener is inserted into the first mounting hole only if the second end edge is closer than the first end edge to the stopping fastener;
• wherein an underplate fastener is at least partially located between the banjo plate and the surface of the hydraulic component when the banjo plate is attached to the hydraulic component;
• and
• wherein the surface includes a second mounting hole configured to receive an underplate fastener, wherein the underplate fastener protrudes from the surface by a second distance when the underplate fastener is inserted into the second mounting hole, wherein the second distance is shorter than the plate distance by which the banjo plate is spaced apart from the surface when the bolt is screwed into the port, whereby the banjo plate is configured to cover the underplate fastener when the underplate fastener is inserted into the second mounting hole and the bolt is screwed into the port.

A process for assembling a hydraulic component mounting assembly comprising:

• causing a surface of the hydraulic component mounting assembly to get at least partially in contact with a front surface of the drum brake backplate;
• inserting a stopping fastener into a first mounting hole, whereby the stopping fastener clamps, in combination with the surface, a respective edge of an at least one drum brake backplate aperture;
• causing a positioning notch to partially surround a stopping screw;
• inserting a bolt into an opening of the banjo plate and screwing the bolt into a port;
• wherein inserting the stopping fastener into the first mounting hole, the stopping fastener clamps, in combination with the surface, the respective edge of the at least one drum brake backplate aperture:
• and
• inserting an underplate fastener into a second mounting hole, whereby the underplate fastener clamps, in combination with the surface, the respective edge of the at least one drum brake backplate aperture.
