Principle of functioning of the gauge-switch of level of a brake liquid
Design of the vacuum amplifier of brakes The scheme of the organisation of a drive of a lay brake
All models of cars considered in the present Management are equipped by hydraulic brake system with vacuum strengthening. Both on forward, and on back wheels of the car brake mechanisms of a disk design are established. All brake mechanisms are equipped by self-regulators. The hydraulic system consists of two independent contours, - forward and back. In default one of the contours, the second continues to function, providing the car adequate braking. The scheme of connection of hydraulic lines of brake system is presented on an illustration. The special control lamp built in in an instrument guard notifies the driver on infringement of serviceability of functioning of brake system, and also about excessive falling of level of a brake liquid. The main brake cylinder (ГТЦ) ГТЦ it is established on assemblage of the servo-driver of the vacuum amplifier of the brakes, fixed on a back partition of an impellent compartment. From above the big tank of a hydraulic liquid equipped with a tight plastic cover is located on the cylinder. ГТЦ has the dual design providing functioning of two independent hydraulic contours. Pressure of a liquid in each of contours is forced by the individual piston in the main cylinder. Inside tightly executed tank GTTS the gauge-switch of level of a liquid is built in. At lowering of level of a brake liquid below some limit the gauge-switch provides operation built in in a combination of devices of a control lamp. The Gauge-switch has язычковую a design with the constant magnet built in a float and is is normal-opened. Until the float settles down above язычкового the switch, the contour of a control lamp remains opened. At falling of level of a liquid approximately on 30 mm below the maximum mark the float is combined with the magnet built in it with язычковым the switch, providing activation of the last and, accordingly, short circuit of a chain of a control lamp.
The vacuum amplifier of brakes The amplifier uses depression created in the inlet pipeline for increase of efficiency of functioning of a hydrodrive of brake system. The servo-driver of the vacuum amplifier is fixed on a back partition of an impellent compartment in the last. The vacuum amplifier enters into a standard complete set of all models «8 inches + 9 inches». Lay brake The trosovyj drive of a lay brake is brought to brake mechanisms of back wheels of the car, - приводные cables fasten to executive levers of brake boots of a lay brake. Protivootkatnaja system The protivootkatnaja system serves for simplification трогания the car standing on lifting (Razdel Protivootkatnaja system - the device, a functioning and safety measure principle see). System of antiblocking of brakes (ABS) ABS prevents premature blocking of wheels of the car at sharp braking (the Section System of antiblocking of brakes (ABS) - the general information, a functioning principle see). System of dynamic stabilisation (VDC) VDC (the Section System of dynamic stabilisation (VDC see) - the general information, a functioning principle) provides increase of stability of movement of a vehicle at movement on a slippery road covering or fulfilment of the sharp maneuvers connected, for example, with a detour of obstacles in high speed. In the work VDC uses functions ABS and, besides functions of direct appointment, carries out also function антипробуксовочной monitoring systems/monitoring systems (TCS). Service of brake system On termination of any of procedures of the service, connected with removal or dismantling any of components of brake system without fail check efficiency of functioning of brake system and, only having made sure of full serviceability of its operation, start car operation. Trial runs should be made on a pure dry and equal road covering. Check efficiency of braking of a vehicle on various speeds of movement and various efforts of squeezing of a pedal of a foot brake. The car should be braked in regular intervals, keeping thus course stability. Try not to suppose the premature blocking of wheels fraught with loss of the control over management. Remember that to number of the factors affecting efficiency of braking of a vehicle, the condition and pressure of a rating of tyres, level of loading of the car and correctness of geometry of a suspension bracket concern. Safety measures At service of components of brake system of cars it is necessary to observe some special safety measures: a) For refuelling of brake system use only a hydraulic liquid of class DOT 3; b) Frictional overlays of brake kolodok/boots can contain unhealthy asbestos. Try not to inhale a brake dust, do not blow off its compressed air. To rubbing of components of brake mechanisms apply only special cleaning structures; c) Watch observance of all demanded admissions and efforts of a tightening of fixture. At service of components use only the serviceable tool. At the slightest doubts address for the help to experts. Remember that serviceability of functioning of brakes is traffic safety pledge; d) At the slightest signs of infringement of serviceability of functioning of brake system car operation should be suspended! |
