Brakes and steering of ZIL-4331 cars

___________________________________________________________________________

Pneumatic drive of brakes of a ZIL-4331 car. The pneumatic drives of brake systems with multi-circuit drives of cars ZIL-4331, 433360, 431410, etc.) have a lot in common in the purposes and design of autonomous circuits, in the pneumatic drive and the devices used.


Rice. 2. Diagram of the pneumatic drive of the brake systems of the ZIL-4331 car 1 - compressor; 2 — brake chambers of the front wheels; 3—control valves; 4 — pressure limitation valve; 5 — pneumoelectric sensors for turning on the brake signal; 6 — auxiliary brake system valve; 7 — air distributor; 8 — emergency parking system release valve; 9, 11 — air cylinders of the service brake system; 10 — condensation air cylinder; 12 — taps for draining condensate; 13 — pneumoelectric sensors for pressure drop in brake systems; 14 - triple safety valve; 15 — parking brake valve; 16 — pneumatic cylinders for driving the auxiliary brake system mechanisms; 17 — two-pointer pressure gauge of the service brake system; 18 — two-section valve of the service brake system; 19 — double safety valve; 20 — pressure regulator; 21 — fuse against condensate freezing; 22 — air cylinder of the parking brake system with a sensor for its activation; 23 — air cylinder of the auxiliary brake system; 24 — control valve for the brake system of a trailer (semi-trailer) with a single-wire drive; 25 — control valve for the brake system of a trailer (semi-trailer) with a two-wire drive; 26—single safety valve; 27— accelerator valve; 28 — brake chambers of the rear wheels; 29 — quick release valve; 30 — brake force regulator; 31 — two-line bypass valves; 32, 33 - connecting heads The diagram of the pneumatic drive of the brakes of the ZIL-4331 car is shown in Fig. 2. Compressed air from compressor 1 through the pressure regulator 20, the condensate freeze guard 21, the condensation air cylinder 10 is supplied to the block of protective valves (double 19 and triple 14), which distribute the air, filling the air cylinders of the first four independent circuits: - brake drive front wheels (contour /); — rear wheel brake drive (circuit //); drive of the parking and spare brake systems, as well as the combined drive of the brakes of a trailer or semi-trailer (circuit ///); — auxiliary brake drive and power supply to other pneumatic devices, including vehicle transmission units (circuit IV). Along with this, there is a V drive circuit for the emergency brake release system, which does not have its own air cylinder.

All air cylinders have valves 12 for draining condensate, and all circuits have built-in pneumatic-electric sensors 13 for compressed air pressure drop. A two-pointer pressure gauge 17 is connected to the air cylinders of the two first circuits of the drive mechanisms of the ZIL-4331 service brake system. To check the operation of the brake systems, valves 3 control outlets are installed at various points of the pneumatic drive, to which portable pressure gauges are connected. Circuit I includes an air cylinder 11, a pressure drop sensor 13, a lower section of the brake valve 18, a pressure limiting valve 4, brake chambers 2 of the front wheels and a control valve 3. Circuit II includes an air cylinder 9, a pressure drop sensor 13, an upper section of a valve 18, a brake force regulator 30 with an elastic element, a control valve 3 and brake chambers 28 of the ZIL-4331 rear wheels. Circuit III includes an air cylinder 22, a pressure drop sensor 13, a manually operated parking brake valve 15, an accelerator valve 27, two dual-line bypass valves 31, a quick brake release valve 29, a control valve 3, spring energy accumulators located in the brake chambers 28 rear wheels. This circuit also includes: a single safety valve 26, trailer (semi-trailer) brake control valves 25 and 24, respectively, with a two-wire and a single-wire drive, two automatic connection heads 32, one connection head 33 (type A) and a brake signal sensor 5 that provides light signal when any ZIL-4331 brake system is operating. Circuit IV includes an air cylinder 23, a pressure drop sensor 13, a push-button valve 6 for turning on the auxiliary brake, two pneumatic cylinders 16, a brake signal sensor 5, a control valve 3 and an air distribution box 7, which is designed to supply compressed air to the clutch pneumatic booster, switch gears in the divider, pneumatic windshield wipers and other consumers of compressed air. Circuit V includes a push-button pneumatic valve 8 for emergency release of the parking brake, a dual-line bypass valve 31, a triple safety valve 14 and brake chamber energy accumulators 28. Steering control of ZIL-4331 vehicles The main condition for trouble-free and durable operation of the ZIL-4331 steering control is keeping it clean hydraulic system.

For power steering, only clean filtered oil is used, which is poured through a funnel with a double mesh and a filler filter installed in the pump reservoir. The use of contaminated oil causes rapid wear of the pump and hydraulic booster. The power steering system is filled at the manufacturer with all-season oil for hydraulic systems of R-brand vehicles (TU 38-1011792-71). This oil has a low pour point and contains anti-wear, antioxidant and other additives that improve its quality. When operating the ZIL-4331 power steering system filled with oil P, it is only added to the pump reservoir if necessary. An oil change is performed only when repairing power steering system units. In the absence of oil P, it is permissible to add oils recommended by the manufacturer as substitutes. However, the durability of the pump and steering mechanism is reduced. When adding substitute oil, the oil is changed 2 times a year (in autumn and spring). Rules for adding and changing oil, as well as brands of substitute oils, are given in the “Steering Maintenance” section. If the hydraulic booster fails due to damage to the ZIL-4331 power steering pump or the hydraulic booster itself, or destruction of the pump drive hose or belt, you can only use the steering mechanism for a short time, until the malfunction is eliminated. Long-term operation of a vehicle with inoperative power steering leads to rapid wear of the steering mechanism or its breakdown, since this overloads the thrust ball bearings, steering screw and other parts of the ball nut assembly. The wear of the driveshaft and steering column also accelerates. For the same reason, it is not allowed to tow a car for a long time with the engine not running without hanging its front axle. It is prohibited to stop the engine until the vehicle comes to a complete stop, and also to move with the engine not running on descents or coasting along a horizontal section of the road. In these cases, the ZIL-4331 power steering pump stops working and the force on the steering wheel and on the steering mechanism parts increases sharply. When maneuvering and getting out of deep ruts when driving on bad country roads, it is forbidden to hold the steering wheel turned all the way in one direction or another for a long time.

In this case, the pump operates on the safety valve, which causes rapid heating of the oil and can lead to pump failure. To continue driving in the event of failure of the power steering hoses of the ZIL-4331, connect the discharge hole of the pump to the return pipe on the pump reservoir, close the discharge and return holes of the steering mechanism with wooden plugs or in another way that provides protection against the ingress of dirt or foreign bodies, and add oil. With such movement, the engine must operate at the lowest possible crankshaft speed; monitor the temperature of the oil in the pump reservoir and if it gets too hot, stop the car so that the oil cools down.
