I. Core Specifications (Estimated Values)
1. Model: ZBMT4-400FHB
• ZBMT: Likely denotes "Braked Wheel Track Motor" (Zhì Dòng Lún Shì Guǐ Dào Mǎ Dá).
• 4: Design series or size code.
• 400: Displacement (unit: cm³/rev), indicating oil volume per revolution.
• FHB: May represent "Braked (Fǎn Zhì) High-Pressure (Gāo Yā) Version."
2. Key Performance Metrics:
• Rated Pressure: 250–350 bar (common high-pressure range in the industry).
• Peak Pressure: Up to 400 bar (short-term overload capacity).
• Speed Range: 0–500 rpm (low-speed, high-torque characteristics).
• Braking Torque: Estimated at hundreds to thousands of N·m (specific data required for confirmation).
• Power Range: Approximately 50–100 kW (dependent on pressure-flow matching).
3. Structural Features:
• Brake Type: Spring-applied, hydraulically released (common design).
• Motor Type: Swashplate axial piston motor (efficient and compact).
• Mounting Style: Flange or hub-mounted (suitable for direct wheel drive).
• Sealing Design: High-pressure shaft seals to prevent leakage.

II. Typical Applications
1. Construction Machinery:
• Driving systems for road rollers, pavers, excavators, etc.
• Ideal for scenarios requiring precise speed and braking control (e.g., climbing, parking).
2. Agricultural Machinery:
• Steering or drive systems for combine harvesters, forage harvesters, etc.
• Adaptable to muddy or sloped terrains.
3. Industrial Vehicles:
• Hydraulic drive wheels for forklifts and stackers.
• High reliability and low maintenance for logistics equipment.
4. Specialized Equipment:
• Heavy-duty braking applications in mining machinery or drilling platforms.

III. Technical Advantages (Estimated)
1. Efficient Braking:
• Hydraulically released, spring-applied design ensures safe parking during power failure or malfunction.
• Short braking response time for emergency stops.
2. High-Pressure Tolerance:
• Designed for high-load conditions, extending service life.
• Optimized shaft seals and bearings to minimize leakage and wear.
3. Modular Design:
• Compatible with various pumps and valves for flexible hydraulic system integration.
• Easy maintenance to reduce downtime costs.

IV. Selection Considerations
1. Parameter Verification:
• Obtain specific displacement, pressure, speed, and braking torque data from the supplier.
• Match system flow and pressure to avoid motor overload or inefficiency.
2. Environmental Adaptability:
• Confirm operating temperature range (e.g., -40°C to +80°C).
• Check protection rating (e.g., IP67) for outdoor or harsh environments.
3. Brake Compatibility:
• Ensure brake compatibility with the vehicle’s control system (e.g., CAN bus, electrical interfaces).
• Consider brake release pressure alignment with hydraulic system pressure.
