Description
Technical Field
The utility model relates to an accelerator pedal support belongs to automobile manufacturing technical field.
Background
The motive machine exhaust auxiliary braking system is a device which can decelerate an automobile, keep stable speed when the automobile descends a long slope and improve the driving safety, and is mainly used for commercial vehicles. The brake drum and the brake friction plate are prevented from being overheated due to long-time service of service brake, so that the brake efficiency is reduced, and even the brake capacity is completely lost.
The auxiliary exhaust brake of engine has the working principle that an exhaust throttle valve is arranged between an exhaust main pipe and a silencer, and the exhaust back pressure of the engine is improved through exhaust throttling, so that the negative work in the exhaust stroke of the engine is increased. This is typically done by an electrical system including an exhaust assist switch (i.e., an exhaust assist brake switch), a throttle switch, a clutch switch, a solenoid valve, etc.
The existing engine exhaust auxiliary brake system mostly adopts an exhaust auxiliary switch to control the on-off of an electromagnetic valve, and the electromagnetic valve controls air pressure to control the opening and closing of an exhaust valve. When the auxiliary discharge switch is closed, the electromagnetic valve closes the air inlet valve and opens the exhaust valve under the action of the valve spring, so that the brake control air chamber of the electromagnetic valve is communicated with the atmosphere and isolated from the air storage tank. When the auxiliary exhaust switch is opened, the electromagnetic valve is opened, so that the exhaust valve is closed, the air inlet valve is opened, and the compressed air is filled into the operating air chamber to close the exhaust brake butterfly valve.
The clutch and the accelerator pedal mechanism are provided with the linked switch, when the exhaust brake switch in the cab is turned on, if the accelerator pedal or the clutch pedal is stepped on a certain distance, the exhaust brake switch can not play a role of exhaust braking even if the exhaust brake switch is in a closed position by mistake, so that the phenomena of deflagration, high temperature, black smoke emission and the like caused by poor combustion of the engine are avoided, and the service life of the engine is not influenced. When the exhaust brake is frequently used, such as repeated occurrence on a downhill road or frequent low-intensity brake on a flat road, the exhaust brake switch can be turned on, when the vehicle needs to accelerate, the exhaust brake can be automatically released by pressing down the accelerator pedal, and the exhaust brake can be automatically recovered by releasing the accelerator pedal. When the speed changer needs to be shifted, the clutch pedal is stepped down, and the auxiliary braking action is released, so that the influence of the reduction of the vehicle speed on smooth gear shifting is avoided.
