Pedal de embreagem com cilindro mestre: Desconstruindo 15 Peças críticas para mudanças perfeitas

This is a focused technical deconstruction of the Pedal de embreagem com cilindro mestre montagem para o FAW Jiefang CA3250P66K2L1T1E 6×4 caminhão despejando. Este guia detalha 15 serviceable parts, sourced from the main pedal bracket BOM, that form the complete in-cab clutch control system.

O Pedal de embreagem com cilindro mestre is a critical driver interface, responsible for disengaging the engine’s power from the transmission to allow for smooth gear shifts. On the FAW J6P, this is not a simple mechanical or hydraulic linkage; it is a sophisticated air-assisted hydraulic module. Esse Pedal de embreagem com cilindro mestre conjunto (part of the larger pedal bracket) uses pneumatic pressure from the truck’s air brake system to multiply the driver’s foot force, making the actuation of the heavy-duty clutch feel light and effortless. This deconstruction will analyze the key components of the Pedal de embreagem com cilindro mestre, including the hydraulic oil cup, the air-over-hydraulic booster, the pedal itself, and the electronic interlock switch. Um funcionamento adequado Pedal de embreagem com cilindro mestre is essential for driver comfort and protecting the transmission from damage.

Essencial 1: O “Air-Over-Hydraulic” Lógica (The Booster System)

Este é o coração do Pedal de embreagem com cilindro mestre. This group of components creates the hydraulic pressure to actuate the clutch, and uses pneumatic air to provide the assist.

1. Componente: 'Conjunto de reforço da embreagem’ (1602110-76C) – Quantidade 1
Esse (Comp. 3) is the primary component. É um “master cylinder” integrated with a pneumatic booster. O Hydraulic Logic is that when the pedal is pressed, an internal piston pushes hydraulic fluid from the ‘Clutch oil cup’ (Comp. 2) down a line to the clutch slave cylinder.

O Lógica de Assistência Aérea is what makes this part of the Pedal de embreagem com cilindro mestre special. A small lever (Comp. 14) opens an air valve inside this booster, which uses high-pressure air from the truck’s brake system to do most of the pushing. This reduces driver effort from hundreds of pounds to just a few.

2. Componente: ‘Conjunto do copo de óleo da embreagem’ (1602100-76C) – Quantidade 1
Esse (Comp. 2) is the reservoir that holds the hydraulic (clutch/brake) fluid for the Pedal de embreagem com cilindro mestre. It is mounted directly on top of the ‘Clutch booster’ (Comp. 3) and must be kept sealed and filled to the correct level.

3. Componente: ‘Arm – operação da válvula de ar do reforço da embreagem’ (1602027-50A) – Quantidade 1
Esse (Comp. 14) is the small, precise lever that connects the ‘Clutch pedal’ (Comp. 9) to the air valve on the ‘Clutch booster’ (Comp. 3). Its geometry is key to the progressive feel of the Pedal de embreagem com cilindro mestre.

Essencial 2: O “Mecânico” Lógica (The Pedal Linkage)

This group of components forms the physical linkage of the Pedal de embreagem com cilindro mestre, translating the driver’s foot movement into mechanical force for the booster.

1. Componente: ‘Pedal da embreagem’ (1602037-50A) – Quantidade 1
Esse (Comp. 9) is the main steel lever that the driver presses. It is a heavy-duty component designed to withstand millions of cycles. It is topped with a ‘Pad – pedal de embreagem’ (3504037-50A) para aderência. This is the primary input for the Pedal de embreagem com cilindro mestre.

2. Componente: 'Haste – principal’ (1602091-50A) & 'Casquilho’ (3504061-50A)
Esse (Comp. 8, 11) is the pivot system. The ‘Shaft – principal’ is the large-diameter pin that the clutch pedal and brake pedal both pivot on. The ‘Bushing – eixo do pedal da embreagem’ (Comp. 11, Quantidade 4) are pressed into the pedal to provide a smooth, baixo atrito, and quiet pivot point. Worn bushings are a common cause of a “sloppy” i>Clutch Pedal With Master Cylinder.

3. Componente: ‘Retorno da primavera – pedal de embreagem’ (3504036-50A) – Quantidade 1
Esse (Comp. 13) is a heavy-duty spring. Isso é Return Logic is to ensure the pedal returns firmly to the top position after being released. A weak or broken spring would cause the Pedal de embreagem com cilindro mestre to feel vague and may not fully re-engage the clutch.

4. Componente: ‘Clutch limit block’ (1602038-76C) – Quantidade 1
Esse (Comp. 16) é o “stop block” ou “pára -choque” that defines the upper travel limit of the pedal, preventing it from over-traveling and damaging the switch or linkage.

Essencial 3: O “Montagem & Elétrica” Lógica (Suporte & Switch)

This group includes the main bracket that holds the Pedal de embreagem com cilindro mestre to the cab and the electronic safety switches that integrate it with the vehicle’s ECU.

1. Componente: ‘Clutch pedal bracket’ (1602020-76C) – Quantidade 1
Esse (Comp. 12) is the main structural foundation for the Pedal de embreagem com cilindro mestre. It is a heavy, stamped-steel bracket that bolts to the cab’s firewall. It must be extremely rigid to absorb the force of the driver’s leg and the booster’s air pressure without flexing.

2. Componente: ‘Conjunto do interruptor da embreagem’ (3754030-76C) – Quantidade 1
Esse (Comp. 17) é um interruptor eletrônico ativado pelo pedal da embreagem. O Safety Interlock Logic é crítico. This switch signals the ECU that the pedal is depressed, which performs two functions: 1) It allows the engine to be started (starter-motor safety), e 2) It informs the engine and cruise control that a gear shift is in process. This is a vital electronic part of the Pedal de embreagem com cilindro mestre.

3. Componente: Fastener Group (Q436150, CQ1740510, etc.)
Esse (Comp. 4, 5, 6, 7, 10) is the hardware. This includes the ‘Hex head bolt with groove’ (Comp. 5) and ‘Open lock washer’ (Comp. 10) for securing the ‘Shaft – principal’ (Comp. 8), preventing it from “walking” laterally. The other fasteners secure the booster (Comp. 3) to the bracket, ensuring a rigid, leak-free mount for the Pedal de embreagem com cilindro mestre.
