Steering Pump Mounting Plate Vibration Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing mounting arrangement of the steering pump assembly in vehicles is challenging to service due to space constraints and allows transmission of vibrations and ambient air/noise into the operator cab.
Innovation Solution
A mounting arrangement with a releasable mounting plate, tubal isolation mounts, and a sealing member that secures the steering pump assembly below the floorboard, using aligned apertures and openings to absorb vibrations and prevent air/noise entry, with a handling member for easy removal and reassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the steering pump assembly is mounted on the floorboard of the operator cab, then the steering pump assembly can be easily removed and serviced from within the operator cab, but vibrations from the vehicle structure are transmitted into the operator cab
Solution Approach 1:
The patent introduces a mounting plate with vibration-absorbing material as an intermediary component between the steering pump assembly and the floorboard. This mounting plate serves as a mediator that allows the pump to be mounted for easy servicing while simultaneously absorbing vibrations to prevent them from transmitting into the operator cab. The mounting plate with its vibration-absorbing properties resolves the contradiction by providing both ease of repair and vibration isolation.
2Strength
If the steering pump assembly is mounted on the lower surface of the operator cab, then it is securely fixed, but it becomes difficult to remove and service due to space constraints
Solution Approach 1:
The patent segments the mounting arrangement into a separate, removable mounting plate assembly that can be detached as a unit from the steering pump assembly. This allows the mounting plate with all its fasteners and vibration-absorbing components to be removed together with the pump, making servicing easier. The segmentation enables the mounting system to provide secure fixed mounting during operation while allowing easy removal when servicing is needed.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively isolates vibrations and seals the steering pump assembly from ambient air and noise, facilitating easier maintenance and reducing noise and air ingress into the operator cab.
Implementation Method 1
The mounting arrangement includes a tubal isolation mount located within each first opening of the mounting plate... to absorb vibrations and prevent air/noise entry
Implementation Method 2
The mounting arrangement further includes a sealing member provided between the top plate and the mounting plate and portions of the sealing member are configured to surround each isolation mount and the pump adaptor

AI summary
A mounting arrangement for a steering pump assembly of a vehicle is disclosed. The mounting arrangement includes a mounting plate coupled to a floorboard of the vehicle. A top plate is disposed above the mounting plate and a bottom plate is disposed below the mounting plate. The mounting plate, top plate and bottom plate include a first, second, and third apertures, respectively, which are in alignment with one another along a pump axis. A first, second, and third openings of the mounting plate, top plate and bottom plate, respectively, are in alignment with one another. A tubal isolation mount is located within first opening of the mounting plate. A fastener extends through each isolation mount, each second and third opening and a body of the steering pump assembly. A sealing member is provided between the top plate and the mounting plate.
