A hinged metal shield mounted ahead of an EV high-voltage component deflects crash-driven parts to prevent shorts and simplify access.

A one-way freewheel clutch and planetary gear set enable smooth multi-speed axle shifts without shift collars, reducing weight and control complexity.

A front cover spreads crash loads across cellular sections, enabling controlled deformation that cuts weight while preserving impact protection.

Partitioned electrical and hydraulic rooms give an electric hydraulic excavator dedicated cooling paths, improving temperature control and reliability.

By separating the battery from the cover member, this case enables larger capacity, longer travel distance, lower cost, and easier maintenance.

Controlled fragile zones in a lower connecting member absorb side-collision loads while preserving rear-seat foot space.

Suspension pressure is shifted between driven rear axles during gear changes to limit traction loss, slippage, and instability.

A beneath-cab battery module uses side access and removable fastening to protect battery elements while simplifying installation and maintenance.

Placing the inverter between the battery and operation section saves space, shortens harnesses, and improves service access and stability.

Protective members around a cross-member busbar path reduce deformation, stack interference, and short-circuit risk under external loads.

A layered wheelbase boundary replaces heavy brackets and ladder frames to house batteries with lower weight, high strength, and crash resistance.

A pin-through-tube joint strengthens a vehicle frame against shear and bending loads while supporting traction batteries and powertrain elements.

Direct wheel-integrated electric motors replace engines and gearing to simplify utility vehicles, improve braking, and enable 360-degree turning.
