Non-Deflectable Wheel Steering TRIZ Cases
- Steer-by-Brake Control for Commercial Vehicle Traffic Jams
Dissymmetrical wheel braking creates yaw for low-speed lane following in commercial vehicles without active steering actuators.
- Differential Hydraulic Drive Steering With Variable Wheel Acceleration
Wheel acceleration is varied from steering input rate so left and right hydraulic drives respond more naturally during slow or rapid maneuvers.
- Tank Steer Gear Set Assembly for Tighter Vehicle Turns
A compound planetary gear set and clutches reverse one axle shaft for tight turns without multiple electric machines.
- Four-Bar Linkage Steering Interface for Hydrostatic Transmission Speed Control
A four-bar linkage couples a hydraulic steering cylinder to pump displacement arms via a pivotable input member.
- Steering Control System Actuator for Hydraulic Flow Adjustment
A steering control system actuator adjusts hydraulic fluid flow rate to axle shafts via mechanical coupling with the steering wheel.
- Agricultural Vehicle Crawler Steering Mode Control
Dynamic mode selection adapts crawler track steering to mimic wheeled vehicles, reducing soil accumulation and improving driving comfort.
- Crawler Crane Combination with Rotatable Connecting Beam
Two crawler cranes link via a rotatable connecting beam to double lifting capacity while maintaining operational flexibility.
- Trailer Yaw Control via Selective Wheel Brake Slip
Selective braking on outer wheels creates a yaw moment to rotate the trailer outward, avoiding inner radius contact without adding self-steering axles.
- Work Vehicle Transmission Segmentation and Control
A work vehicle combines outputs from straight-traveling and turning system transmission paths using cooperative stepless devices.
- Reverse Switch Activation Mechanism with Cam and Lost Motion Slot
A reverse switch activation mechanism uses a cam surface to push a plunger, initiating the reverse signal during pedal depression.
- Epicyclic Gear Pivot Mechanism for Military Vehicle Steering
Epicyclic gear trains with dog clutches reverse wheel rotation to enable tight pivoting without skid steering complexity.
- Segmented Hydraulic Drive System for Tracked Vehicles
Segmented hydraulic circuits allow selective pump activation, reducing power losses from oversized components while maintaining maximum tractive force.
- Twin Variator Transmission with Parallel Shafts for Shunt Gear Input
Parallel shafts supply independent drive ratios to shunt gears in a twin variator, resolving packaging conflicts and reducing frictional losses.
- Joystick Control System for Zero-Turn Utility Vehicles
A multi-axis joystick controls vehicle speed and direction through an electric controller.
- Soft Ground Crawling Robot with Dynamic Posture Adjustment
A soft ground crawling robot uses a swinging stepping motor to adjust its body orientation for stable movement.
- Steerable Crawler Chassis Hydraulic Power Split
A steerable crawler chassis uses variable displacement hydraulic motors to redistribute drive energy through a closed circuit for precise steering control.
- Regenerative Steering Differential Torque Management
A regenerative steering differential gear assembly transfers torque between primary and secondary members to drive final drives.
- Coaxial Hydraulic Transaxle Neutral Zone Control
A compact hydraulic transaxle uses a coaxial motor shaft and axle arrangement to minimize assembly complexity.
- Hydraulic Steering Device for Self-Propelled Vehicles
A hydraulic steering device actuates steerable rear wheels via a cylinder and transmits angles to front drive wheels through mechanical linkages.
- Hydraulic Steering Control for Agricultural Tracked Vehicles
Electric power steering controller regulates opposing hydraulic motor speeds to resolve high turning moments in tracked agricultural vehicles.
- Work Vehicle Multi-Mode Turn Control via Steering and Braking
A controller manages steering actuators and brakes to execute multi-mode turns on work vehicles.
