Understand the basic structure of hydraulic wheel side brake
The hydraulic wheel side brake is mainly composed of the following components:
Brake caliper body
Friction plate
Piston assembly
Seals
Hydraulic pipeline interface
Understanding these basic structures helps to better evaluate the applicability and quality of a product when selecting.
Key selection parameters
1.Braking torque requirements
Calculation basis:
Total weight of equipment
Maximum running speed
Braking distance requirements
Slope conditions
Professional advice: The brake torque should have a safety margin of 20%-30% to cope with emergencies and performance attenuation during long-term use.
2.Working pressure range
Standard scope:
Low pressure type: 6-12MPa
Medium pressure type: 12-20MPa
High pressure type: 20-35MPa
Matching principle: It must be matched with the working pressure of the hydraulic system to avoid braking failure or excessive pressure damage to the seal due to insufficient pressure.
3.Installation space limitations
Key points of measurement:
Space dimensions on the inner side of the wheel hub
Installation bolt hole position
Axial and radial clearances
Note: Leave enough heat dissipation space and maintenance gap to avoid poor heat dissipation or difficulty in maintenance due to insufficient space.
Special working conditions considerations
1.Harsh environment applications
Solution:
Choose stainless steel or special coating
Double seal design
Equipped with dust protection cover
Applicable scenarios: places with strong corrosiveness such as mines, ports, salt spray environments.
2.High frequency braking conditions
Technical requirements:
High thermal stability friction material
Forced cooling design
High temperature resistant seal
Typical applications: continuous downhill sections of roads, AGV equipment that frequently starts and stops, etc.
3.Use in low temperature environment
Special Requirements:
Low temperature hydraulic oil compatibility
Anti-cold brittle material
Low temperature start-up performance
Extreme conditions: environments below -40℃ need to be specially customized.
Common selection misunderstandings
1.Only look at the price and not the cost-effectiveness: Low-priced products may pay a greater price for their service life and maintenance costs
2.Ignore matching: The brake must match well with the vehicle control system
3.Ignore future requirements: Possible upgrades and load changes in equipment should be considered
4.Despise installation and debugging: Professional installation is crucial to performance
