Vehicle Motor Bracket Layout for Compact Protected Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional structures for supporting electric motors on vehicles are bulky, heavy, and hinder efficient connection to electrical terminals and driveshafts, limiting their application in electric vehicles.
Innovation Solution
A vehicle structure that includes a motor assembly with a motor bracket between the electric motor and frame housing, allowing easy connection to electrical leads and driveshaft, with the motor assembly, inverter, and On-board Battery Charger arranged along a straight line from the vehicle's front to rear, supported by frame rails.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional frame housing is used to support the electric motor, then the motor is protected from damage, but the housing becomes bulky and makes it difficult to connect the motor to electrical terminals and driveshaft/transmission
Solution Approach 1:
The frame housing is divided into a first portion and a second portion that are selectively positionable relative to each other. This segmentation allows the housing to be configured in different positions to facilitate connections with electrical terminals and driveshaft/transmission while maintaining motor protection, thereby reducing the bulky nature of the conventional single-piece housing.
2Reliability
If a conventional frame housing is used to support the electric motor, then the motor is protected from damage, but the housing becomes unnecessarily heavy
Solution Approach 1:
By dividing the frame housing into two selective portions, the design allows for optimization of each portion's mass and material usage. The portions can be independently designed and positioned to provide necessary protection while minimizing overall weight, avoiding the unnecessary heaviness of conventional monolithic housings.
3Volume of moving object
If the motor assembly and inverter are positioned close to each other, then space is optimized, but connection between electrical components becomes more difficult
Solution Approach 1:
The frame housing portions are selectively positionable, allowing the housing to adapt its configuration based on operational requirements. This dynamic positioning capability enables the housing to facilitate electrical connections between the motor and inverter when needed, while maintaining compact spacing between components for space optimization.

AI summary
A vehicle includes a motor assembly, a chassis, and an inverter. The motor assembly and the inverter are affixed to the chassis at a location where the motor assembly and the inverter are opposed to one another. The motor assembly includes an electric motor, a frame housing, and a motor bracket. The motor bracket is provided between the electric motor and the frame housing, and the electric motor is fixed to the frame housing via the motor bracket. The electric motor includes at least one electrical contact which is structured to be connected to electrical leads which extend between the electric motor and the inverter. The vehicle is an electric powered agricultural machine.
