Fifth Wheel Lubrication Casing for Even Grease Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current lubrication methods for fifth wheel turntables are inefficient, difficult to apply, especially in cold climates, and result in uneven distribution of grease, leading to increased wear and friction, and pose economic and environmental challenges due to excess grease and packaging issues.
Innovation Solution
A lubrication device comprising an elongated, plastically formable casing made from elastic materials like collagen, containing high viscosity grease, which can be shaped to fit the base plate and rupture under pressure to ensure even distribution across the mating surfaces, allowing for quick, clean, and adaptable lubrication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional manual lubrication methods are used, then grease can be applied to the mating surfaces, but the distribution is uneven and the process is time-consuming and difficult in cold climates
Solution Approach 1:
The lubricating grease is pre-filled and sealed within a casing that is designed to be placed on the base plate before the upper plate is positioned. The casing contains the grease in a controlled manner, and when the upper plate is disposed on top, the grease is automatically released and distributed through the pressure applied by the upper plate, eliminating the need for manual application and ensuring even distribution.
Solution Approach 2:
The lubrication system is self-service in that the grease is automatically distributed when the upper plate is placed on the base plate. The pressure from the upper plate ruptures the sealed casing and forces the grease through distribution channels or directly onto the mating surfaces, without requiring external intervention or manual application.
2Ease of operation
If grease is applied manually, then lubrication can be performed, but it is difficult in cold climates and results in excess grease and packaging waste
Solution Approach 1:
The lubricating grease is contained within a flexible casing that can be easily handled and positioned. The casing is designed to rupture under pressure, releasing the grease in a controlled manner. This eliminates the need for traditional packaging and reduces waste, while the flexible nature of the casing makes the lubrication process easy to perform even in cold climates.
Solution Approach 2:
The lubrication device is designed as a disposable unit where the grease is sealed in a single-use casing. After the grease is distributed, the entire device is discarded, eliminating the need for cleaning and maintenance. This reduces packaging waste compared to traditional reusable lubrication systems and makes the process simpler and cleaner.
3Manufacturing precision
If the lubrication device is placed on the base plate and ruptured under pressure, then grease is evenly distributed, but the device must be adaptable to various sizes and shapes of fifth wheel couplings
Solution Approach 1:
The lubrication device incorporates a flexible casing that can dynamically adapt to different sizes and shapes of fifth wheel couplings. The casing is designed to be pliable and capable of conforming to the specific geometry of the base plate, ensuring that the grease is evenly distributed across the mating surfaces regardless of the coupling configuration.
Solution Approach 2:
The casing is made from flexible material that can be easily shaped and adapted to fit various base plate configurations. This flexibility allows the same lubrication device design to be used across different sizes and types of fifth wheel couplings, providing universal adaptability while maintaining even grease distribution through pressure-actuated release.

AI summary
A turntable lubrication device for lubricating sliding mating surfaces of a base plate and an upper plate, the device comprising; —a casing, and—a lubricating grease contained and sealed within the casing, which lubrication device is intended to be manually positioned on the mating surface of the base plate and ruptured under pressure of the upper plate when the upper plate is positioned on top of the base plate, thereby allowing the grease to be distributed between the mating surfaces. The lubrication device is elongated and plastically formable, thus allowing the device to be shaped and curved so that it substantially follows a circumferential shape of the base plate such that the grease is evenly distributed over the sliding mating surfaces.
