206G.207G Type Bogies

6G-type, 2O7G type and casting bolster spring bogie 2O6G span (ram) vary, respectively, 2480,uggs nederland,2560 and 2400, increasing the welded bogie bogie anti-roll capability. 4. Bogie brake 206G, 207G-type bogies and 206 bogie brake Chao same (see Figure 6), bilateral tread brake, brake by phosphorus. To reduce the wear of brake system components to carry out the following improvements: (1) bogie according to a variety of brake lining of steel I-class precision manufacturing, the surface roughness of the rolling stock is reduced to 1991 by ffj, Lane ~ j boats Xia '. . . One by one hairpin. . , Sulfuric acid coriander for a flight one by one, pull the central store 5l}】 suspension II6 turn: _J aircraft system power devices, Mi read a marketing suite gap (30mm diameter pin to set an example A) from 1. O ~ O. 58ram to 0.7O ~ O. 28ram, reducing the pin diameter between the sets!, Jj runout, subtract, vibration, anti-wear rate, meaning the effective increase in wear of the casing to extend the life of the brake pin sets. (2) The Brake Head hung suspended in between the seat cushion pad did not eliminate the gap between the horizontal seat hanging on the brake, Brake Head,mbt uk, the vibration of the brake beams to impose constraints and restrictions, can improve the system of higher moving beam axis head, Brake Head casing wear and brake beam, the line to eliminate friction and noise. (3) the removal mitigation brake beam springs, re-established as brake beam safety support. 5. Two transmission power device 206G, 207G-type bogies are installed, a truck alternator 8kW Induction and secondary transmission, by the shaft conveyor. Gear box, master-slave pulley,abercrombie outlet, cold V-belt, universal shaft, generator and belt tensioner and other components (see Figure 7). As a result of different motor drive axles (RD4 and RDl0), 206G,mbt uk, 207G bogie drive shaft by various agencies. 206G-type switch-type frame with the motor axle RD4, and a bogie 206 Cheung, tapered back with the main pulley fixed on the RD4 sleeves type axle 4) 1lO outside the Chung journal 』-, i ~ j207G Bogies the main pulley is mounted on the ~ IlRD. Strong link axle shaft end link axis. The link shaft M11O thread and special three keys and RD. Solid shaft combination, can ensure smooth transmission, reliable work. The two main technical parameters of transmission and generators, such as Bu: Motor type motor maximum power (kW) motor limit speed r / min motor power minimum speed r / rain for a total transmission ratio KFW 1084OOO95O2O63.932O7G4. O7 transmission ratio gearbox models P55JK-AB 291-type connector to the motor hanging in the middle of the motor-side beams, improving the bogie 3 side of the box spring of the stress condition, thereby reducing the bogie frame caused by the mass eccentricity Additional nod and roll vibration vibration, the vibration of the bogie has also been improved. 6. Hotbox detector probe from the heat resistance, junction boxes, conduit, wire and bolt axle temperature detection devices and other components. Each 206G, 2O7G bogie allowed only a 5-pin plug and car control by 1991 Khin Road vehicles-r 'l · 77 · Mexican bandits stripped 0g star meal' · T8 · more cloth for carrying baby foot basis j aldehyde Dai Ying; hole h ring system phase line outlet. Facilitate the transit operation facelift bogie. Fourth, test 206G, 207G-type bogies and related components for the steel, welded bogie of the static strength and fatigue testing; high-speed (200km / h) test bed; vehicle through small radius curves (R90m) test; Vehicle Derailment coefficient, wheel load reduction rate, overturning factor, tests for determining the maximum lateral force; vehicle wheel weight determination; through the standard gauge, broad gauge rail vehicle testing; line dynamic test and train braking distance test. The results showed that, 206G, 207G Bogie basic performance indicators to meet the contract specification requirements. V. CONCLUSIONS In summary, the tourist bus with the 206G, 207G D-type passenger car axle, the design is reasonable, in reducing wear, improving the quality of operation has made some progress, for the future transformation of passenger car 206 and other new Bus transfer frame design, manufacture and accumulated useful experience. The retention problem is: (1) welded frame, bolster strength reserve is too large, so the weight is too large. (2) Bolster layout of the vertical bar of the vibration of the bogie, the future should be studied. (3) The emergency brake, can not guarantee that the braking distance required (V ~ 120km / h when no more than 800m, V ~ 140km / h time is not greater than 1200m). Railway Vehicle by 1991
