The parking brake - a design and the principle of functioning

Design of the mechanism of the parking brake

1 — the Brake board
2 — the Lock ring
3 — the Spring washer
4 — the Executive lever
5 — the Forward boot
6 — the Back boot
7 — Razzhimnaya a spring
8 — Razzhimnaya a level
9 — Directing boots

10 — the Returnable spring of a forward boot
11 — the Returnable spring of a back boot
12 — the Adjusting spring
13 — the Regulator
14 — the Plate of the directing spring
15 — the Directing spring
16 — the Anchor finger
17 — the Cap of a service opening of access to the regulator


Design of the hummock drive of the parking brake

1 — the Lever of the drive of the parking brake
2 — the Sensor switch of raising of the parking brake
3 — the Lock-nut
4 — the Adjusting nut
5 — the Equalizer
6 — the Arm
7 — the Collar
8 — the Left driving cable
9 — the Clamp (only for models with disk brake mechanisms of back wheels)

10 — the Right driving cable

Efforts of a tightening of threaded connections, Nanometer

T1: 5.9
T2: 18
T3: 32


Principle of functioning of the parking brake

1 — the Driving cable
2 — the Executive lever
3 — Razzhimnaya a level
4 — the Boot A

5 — the Boot B
6 — Returnable springs
7 — Anchor fingers
8 — the Point of support "Р"


Designs of the mechanism and the hummock drive of the parking brake are shown on illustrations.

When raising of the control lever located between forward seats, the executive lever of the back brake mechanism under the influence of the effort developed by a driving cable develops a razzhimny level concerning the point "Р" in the direction of "F". Being developed, the razzhimny level presses brake boots to a working surface of a drum. Boots have a floating design and keep on a brake board by means of anchor fingers, and the boot A is displaced under the influence of the effort developed by directly razzhimny level whereas the boot B nestles on a drum surface under the influence of force of reaction of "F" through the point of support "Р".

At an otpuskaniye of the parking brake the driving cable is weakened and boots come back to starting positions under the influence of the efforts developed by returnable springs.
