A vehicle brake device

technical field

Background technique

With the improvement of my country's economic level, the number of private vehicles in my country has grown rapidly and has become the first in the world, and the total production of vehicles in my country is also the first in the world. Safety performance is the most critical indicator of vehicle performance, and braking performance is the key among the keys. In the conventional definition, the braking system is a series of special devices used on the vehicle to make the outside world (mainly the road surface) exert a certain force on some parts of the car (mainly the wheels), so as to perform a certain degree of forced braking on it. Conventional brake devices include engine brake, parking brake, service brake, secondary brake and auxiliary brake. Among them, engine braking refers to the speed at which the vehicle is restrained by the engine, which has high requirements for the entire vehicle, and is mainly suitable for high-end vehicles or special vehicles; parking brake refers to the use of hand brakes or the parking gear in automatic gear, Lock the transmission shaft or the rear wheel, but it is mostly used in the parking state, and the effect is not good or applicable in the state of driving or emergency braking; the driving brake, also known as the foot brake, is used by the driver It is operated by feet; the second brake refers to a set of devices that can ensure that the car can still slow down or stop when the service brake system fails; auxiliary brake refers to vehicles that often drive in mountainous areas and some special-purpose vehicles. Vehicles are equipped with related braking devices in order to improve driving safety and reduce the performance degradation of the driving brake system and the wear of the brakes. To sum up, the more effective braking methods in the driving process are the service brake, the second brake and the auxiliary brake, but there are also the following problems: (1) on the service brake, the conventional disc Braking is easy to cause a locked state due to emergency braking, especially in the case of high-speed operation, emergency braking will easily cause a high pressure difference and fit between the brake pad and the brake disc, making it impossible to separate again, causing the vehicle to fail. If the disc brake effect is weakened, it will lead to ineffective braking; (2) Conventional service brakes generally control the brake effect according to brake friction or pressure. For brake pads The requirements are high, and the brake oil needs to be continuously replenished. What is more critical is that during the long-term occlusal wear process, it will cause sensor deviation and cause brake failure, and the brake life is short; (3) In the emergency braking process , the most likely problem is inertia rollover, and most of them are inertial forward rollover and rollover; the current second braking device is seldom equipped with relevant devices to suppress this situation. Therefore, in view of the above problems, it is urgent to design and develop a vehicle service braking device.
