30kN.m Construction Machinery Vehicle Brake Pressure Torque Testing Machine Construction Machinery Vehicles
Brake Moment Tester Functional Parameters: →30kN.m construction machinery vehicle brake pressure torque testing machine, evaluating the impact of brake air pressure changes on braking torque during continuous operation, the effect of braking torque variations on brake air pressure, and the influence of temperature changes on brake performance. →Remove grease, coatings, and other foreign objects from the friction surfaces of brake linings, pads, brake drums, and discs. Install the brake sample onto the HRJ fatigue testing machine according to the actual vehicle state, tightening with the specified torque for connecting bolts and nuts. Conduct brake break-in tests and brake fatigue strength tests. Check for deformation of pin holes in drum brake support areas, deformation and damage of brake shoes, displacement of friction linings, deformation of brake backing plates, and deformation and loosening of mounting points. For disc brakes, inspect deformation at the brake pad insertion points, deformation of brake calipers, deformation and damage of brake pads, and deformation and loosening of mounting locations. →Automotive brake fatigue performance test temperature measurement device, measuring and recording brake temperature, brake lining/pad temperature, temperature changes within 15 seconds after the brake drum/disc stops rotating. Measure brake fluid temperature changes, with temperature measurements taken at 1-minute intervals after brake test actions are released. →20bar/s air pressure control, brake drum deceleration braking torque 3.5m/s2 or 5.9m/s2, braking cycle 5s±0.5s, braking time less than 1.5s, brake drum/disc rotation angle greater than 15°, number of brake applications 5000/50000 times. Carrier frequency signal conditioning. →Plot rotation angle-time curves for brake drums/discs, braking torque-time curves, forward rotation time curves for brake drums/discs, return time curves for brake drums/discs, braking time curves, braking torque stabilization time curves, brake drum/disc idle time curves, and brake temperature control curves. |
