Vehicle Speed Reduction Device Mounting Structure Linear Force Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mounting structures of speed reduction and brake devices in vehicles require increased strength and size to handle braking forces, leading to increased weight and size, which hinders miniaturization and weight reduction.
Innovation Solution
The mounting structure positions the clamping portion, caliper mounting portion, and casing mounting portion on a substantially straight line parallel to the braking force direction, enhancing rigidity with cross members and arm support portions, allowing for reduced size and weight while maintaining structural integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the mounting plate is strengthened by increasing plate thickness or width to receive braking moments, then the strength is improved, but the weight and size increase
Solution Approach 1:
The patent repositions the caliper mounting portion and casing mounting portion along the braking force direction (creating a linear arrangement), thereby changing the spatial dimension of force transmission. This dimensional reconfiguration allows braking forces to be transmitted directly through the mounting structure without generating large moments, eliminating the need for increased plate thickness or width while maintaining strength.
Solution Approach 2:
The patent changes the geometric parameter arrangement by positioning the clamping portion, caliper mounting portion, and casing mounting portion on a substantially straight line parallel to the braking force direction. This parameter change in spatial configuration transforms the force transmission path, reducing the mechanical moments acting on the mounting plate and allowing for weight reduction.
2Strength
If the mounting plate width is increased from front surface to back surface to receive braking moments, then the strength is improved, but the device size increases
Solution Approach 1:
The patent reconfigures the mounting structure by arranging components along the braking force direction rather than increasing width in the front-to-back dimension. This dimensional change in force transmission path eliminates the need for increased mounting plate width while maintaining the capability to receive braking forces.
3Weight of moving object
If the mounting structure is miniaturized and lightened, then the weight and size are reduced, but the ability to receive braking forces is compromised
Solution Approach 1:
The patent achieves miniaturization and weight reduction by fundamentally changing the dimension of force transmission - arranging the clamping portion, caliper mounting portion, and casing mounting portion in a linear configuration parallel to the braking force direction. This allows small, lightweight mounting structures to effectively transmit braking forces without generating large moments that would require heavy reinforcement.

AI summary
A mounting structure for a speed reduction device of a vehicle includes a vehicle frame, a casing mounted on the vehicle frame at a casing mounting portion, a brake caliper mounted to the casing at a caliper mounting portion, a brake disc mounted on a drive axle of the vehicle, and a clamping portion mounted on the brake caliper for applying clamping force to the brake disc. The clamping portion, the caliper mounting portion, and the casing mounting portion are positioned on a substantially straight line, and are positioned substantially parallel to the direction of braking force.
