Technical requirements for cars to use

When servicing cars monitor the condition of the friction surfaces of the parts, welds, rivets and bolts, cracks in the details, and sites cart, check the axle unit work, drive undercar generator, center, nadbuksovogo of spring and spring suspension.

Check the condition of trucks for maintenance of passenger trains at stations formation or turnover, as well as maintenance items along the way. In addition, six months after the trolley was monitored at a single technical audit and before each seasonal traffic - summer and winter. Bogie wagons in international traffic, including 1435 mm, are served at the same time regardless of their location (under the car or on the way of sludge item rearrangement of cars).

Depending on the nature of the damage trucks eliminate faults directly in, and after uncoupling the car of the train or its submission to a special way, where there is a corresponding process equipment.

Never setting in train and the survey in their carriages with a cart, where there is a mismatch gaps between horizontal and vertical skolzunami, and the gap between the bolster and the bogie frame or plank on frame truck LSC and LSC-5-CRI less than 20 mm. To bolster, cart frame, and central parts of cradle hanging cracks of any size are not permitted. Unacceptable failure in the safety straps securing knots, cracks or breaks brackets and mounting parts shock absorbers, cracks pyatnikov, thrust bearings, skolzunov and defects of attachment.

The cars with trucks KHP CRI-bearing body is carried on horizontal skolzuny. In this regard, the gap allowed by at least 9 mm should be controlled between the hard edge pyatnika and glides. On the surface of the horizontal skolzunov not allowed bully. In addition, the trucks of this type of cast iron insert edge elevation above the box skolzuna bolster should not be less than 11 mm.

Hydraulic shock absorbers replaced if cracks in the cylinder tank, mounted or in heads, leakage of oil from the absorber, no rubber bushings in the heads of the absorber and at least 7 mm gap between the body and the shock absorber bracket bolster. At border formation and turnover dampers replace if since the last revision more than six months or the period of the audit will expire on the way. When sending the train in flight shall also be pureed casing vibration absorbers of 2 mm.

Do carts CMV gaps between the frame and the frame trolley car and truck between the frame and the ceiling permitted axle box of at least 30 mm. In the case of a weakening of rubber packet leashes carts LSC-CRI package replaces.

When checking the technical condition of cars trucks emphasis on serviceability elements of wheel sets, axle-box springs and central suspension, suspension system and bolster beams, pallet, central suspension spring suspension (tie rods, beads, earrings, pendants support beams), friction damper mounting assembly, safety brackets and bolts, trailing leashes carts LSC-CRI.

Bogie carriages KHP CRI-I, LSC-CRI II, LSC-5 and CMV, following refurbishment, meet high technical requirements and apply to train at a speed of 120-140 km / h Under coaches for speeds up to 200 km / h only with the cart rolled TSK-l, technical condition must comply with the special instructions.

When the single technical revisions (ETP) of passenger cars are subject to maintenance carts with rolling out from under the car in the event of a change of wheel sets a limit on rental, with a condition requiring podemki body, in wagons in international traffic, with cars circulating at speeds of 140 km / h and above, in the presence of wheel sets with a drive of the generator from the middle of the axis, the axis of the neck from the front, with the gear-belt-drive line. In other cases, the technical inspection is performed without the rollout carts out of the car. ETP is performed on designated routes of repair, equipped with the necessary equipment, mechanized devices. When a single technical audits for inspection and repair in specialized units to shoot high-speed bogies regulators pressing brake pads, sensors protivoyuznyh regulators, hydraulic shock absorbers.

Wheel sets with gearboxes in the middle of the shaft, or from the front axle, and with the drive pulley belt drive to roll out technical inspections of the relevant production areas. While sensors monitor the heat boxwood dismantled after disconnecting their wires in Junction box.

Bogie frame is cleaned of dirt and subjected to careful visual inspection. Violations of welds and cracks are not allowed. Bogie frame repair welding is performed in accordance with instructions for welding and surfacing in the repair of cars and containers (UBC 32 Color 201-78).

We rolled out carts, in addition, controls the horizontal bearing surfaces skolzunov, glides. On the frame of the car and check the surface pyatnikov skolzunov. Wear them to be a thickness of 30 mm. Side bearing trolleys LSC-CRI regardless of the thickness should be no gaps, scratches and grease grooves have a depth of 3 mm. Skolzuna output of the box, wait at least 13 mm, no more than regulate the staging of two rubber pads with a total thickness less than 8 mm. The depth of the side bearing in the box may be at least 17 mm. Before podkatkoy trolley car under side bearing grease sulfurized lubricant produced by TU-32 (CT-551-73) or the brand US-2 (GOST 1033-79). The use of other brands of lubricants for this purpose is not allowed.

Even wear horizontal and vertical overlaps skolzunov carts LSC-5 and CMV may be a maximum of 8 mm. With more wear pads or replace skolzuny like and rubber gaskets, having fissure damages or lost elasticity

All control work is performed on a podkachennyh bogies that are on the straight and horizontal (well thought) section of railway track. Here, check and adjust the gap Mezhno side and end vertical skolzunami bolster beams and skolzunami bogie frame.

On trolleys CMV controlled clearance between the top surface of the neck cradle (reference) beam and the upper wall of the suspension holes no more than 19 mm. If the clearance exceeds the allowable size, it is a fault in the central suspension, which in this case is the case and replace defective parts. Safety Brackets carts are cleaned, checked for cracks and breaks, as well as the accuracy of their installation.

Verifiable gap between the world of pan and set support washers safety rods hanging trolley KHP Central Research Institute of I-must be from 1 to 4 mm. If necessary, adjusted gap between the top shelf trigger guard and bolster the lower plane, the maximum value of which is: for trucks LSC-5 - 70 mm, LSC-Research Institute of I -140 + 5 x 10 mm, LSC-CRI II - 140 + -20 mm dimension LSC-CRI CRI 85 + 10 -5 mm and CMV - 23 + 10 -5 mm.

In cars with the support of the body on the horizontal skolzuny carts LSC-controlled gap between CRI pyatnikom and glide as well as in the TO-2, should not be less than 9 mm. Check that the longitudinal leashes on their symmetry with respect to the frame of the trolley, and the location bolster and hydraulic shock absorbers.

The gaps between the horizontal skolzunami carts CMV and CVD-5 and car frame is adjusted to the size of not more than 6 and less than 2 mm, ie to the same size as in the preparation of maintenance cars in flight (TS-2). Check and if necessary adjust the gap between the longitudinal beam bogie frame and the ceiling roll boxes, trolleys component in CVD and CVD-5-CRI at least 56 mm, and carts as CMV at least 43 mm.

Ends unified technical audit node test friction shock absorbers nadbuksovogo spring suspension. Here, pay attention to the density of the crown nuts fastening shpintonov. With the weakening of the mounting tighten the castle nut until fully extended disk spring, set up a cone. To be able to set the pin setting washers thickness of 5 mm. Diameters of regulatory goals and there should match the diameter disc springs.

Unified technical inspection trolleys TSC-1 (for a passenger train PT-200) is made only with the rollout of them from cars. Dates and technical requirements for maintenance of these trucks are set by the Ministry of Transport.

Revision trolleys 1435 mm is similar to broad gauge trolleys with additions and changes that characterize their design features. Adjustments in the ETP on trolleys 1435 mm, are laid up, be done with a special device - a hydraulic press, which allows to simulate a load equal to the load of the car body.

Vertical clearance between the longitudinal beam and axle boxes have bogies LSC-CRI CRI dimension should be 30 mm, and a trolley LSC-CRI Envelope 0-T - 55 + 10 - 20 mm with a missing adjusting bolt.

The gap between the bolster and pallet trucks at LSC-CRI for 18 local coaches RIC dimension is set to 70 mm, and for the 30-seat cars with forced ventilation dimension RIC-64 mm for the 30-seat coaches dimension RIC with air conditioning - 65 mm.

Under a load equal to the weight of the car body, the gap between the ceiling and the upper parts of the longitudinal girder trolley shall be equal to the trolley CMV 53 - 5 mm. CVD in the cart-CRI CRI dimension, this gap is 30 mm as measured between the ceiling and the upper parts adjusting screw. The gap should be at least 5 mm in the sum of not more than 25 mm, which is controlled by a leash with no load on the truck. When inspecting or installing hydraulic damper control clearances, which should not be less than 7 mm. To obtain these clearances used rubber washers, and the adjustment process is carried out at the released brake rigging.
