Abstract
A support structure for supporting a hydraulic unit of a brake system on a vehicle body is provided. The hydraulic unit has a housing and a motor attached to a lateral side surface of the housing. The hydraulic unit has a predetermined support width and is supported at two or more support positions on a vehicle body by way of resilient members. The support structure comprises a support member for supporting the hydraulic unit in such a manner as to allow a gravitational axis of the hydraulic unit to be disposed within the support width when viewed in a side elevation. A hydraulic unit arrangement and a method for supporting the hydraulic unit are also provided.

A support structure for supporting a hydraulic unit of a brake system on a vehicle body, wherein the hydraulic unit has a housing with a lateral side surface and a lower side surface, wherein a motor is attached to the lateral side surface of the housing, the support structure comprising:
- a support member for supporting the hydraulic unit on a vehicle body at two or more support positions by way of resilient members,
- wherein the support positions are spaced apart from each other to provide a predetermined support width, wherein the support member is attached at one of the support positions to the lateral side surface of the housing and at another of the support positions to the lower side surface of the housing, and wherein the support positions are arranged so that a gravitational axis of the hydraulic unit defined by a center of gravity of the hydraulic unit is disposed within the support width.
A hydraulic unit arrangement for a vehicle brake system comprising:
- a hydraulic unit having a housing with a lateral side surface and a lower side surface, wherein a motor is attached to the lateral side surface of the housing;
- and
- a support member for supporting the hydraulic unit on a vehicle body at two or more support positions by way of resilient members,
- wherein the support positions are spaced apart from each other to provide a predetermined support width, wherein the support member is attached at one of the support positions to the lateral side surface of the housing and at another of the support positions to the lower side surface of the housing, and wherein the support positions are arranged so that a gravitational axis of the hydraulic unit defined by a center of gravity of the hydraulic unit is disposed within the support width.
A method of supporting a hydraulic unit of a brake system on a vehicle body by means of a support member, wherein the hydraulic unit has a housing with a lateral side surface and a lower side surface, wherein a motor is attached to the lateral side surface of the housing, wherein the support member supports the hydraulic unit at two or more support positions by way of resilient members, wherein the support positions are spaced apart from each other to provide a predetermined support width, wherein the support member is attached at one of the support positions to the lateral side surface of the housing and at another of the support positions to the lateral side surface of the housing, the method comprising the steps of:
- determining the support positions so that a gravitational axis of the hydraulic unit defined by a center of gravity of the hydraulic unit is disposed within the support width.
A support structure for supporting a hydraulic unit of a brake system on a vehicle body, wherein the hydraulic unit has a housing having a lateral side surface and a lower side surface, wherein a motor is attached to the lateral side surface of the housing, wherein the hydraulic unit has a predetermined support width and is supported at two or more support positions on a vehicle body by way of resilient members, wherein the support positions are respectively provided on the lower side surface and the lateral side surface of the housing in such a way that a gravitational axis of the hydraulic unit defined by a center of gravity of the hydraulic unit is disposed within the support width, the support structure comprising:
- a bracket attached to the vehicle body and having a lower side support surface nearly in parallel with the lower side surface of the housing and a lateral side support surface nearly in parallel with the lateral side surface of the housing,
- wherein one of the resilient members is disposed between the lower side surface of the housing and the lower side support surface of the bracket so as to have a support axis that extends substantially perpendicularly to an axis of rotation of the motor and is located on a plane on which the axis of rotation of the motor is located, and wherein another of the resilient members is disposed between the lateral side surface of the housing and the lateral side support surface of the bracket so as to have a support axis nearly in parallel with the axis of rotation of the motor.
