Abstract

The invention discloses a self-positioning plastic vacuum tank and belongs to the field of vacuum tanks used for automobile brake vacuum assisting power systems. The self-positioning plastic vacuum tank comprises an upper cover, a lower cover and a sealing ring. The upper cover and the lower cover are in sealed connection through the sealing ring. An air inflow hole, an air outflow hole and a pressure sensor are further arranged on a tank body of the plastic vacuum tank. Self-positioning devices matched with each other are further arranged in the connecting position of the upper cover and thelower cover. The connecting position is coated with the sealing ring. The self-positioning plastic vacuum tank is improved in order to solve the technical problems that an existing iron or stainless steel vacuum tank is complex in machining procedure, low in use quality and easy to corrode and pollute, the rotation angles of an air inflow hole and an air outflow hole of the vacuum tank cannot be controlled, an upper cover and a lower cover are poor in sealing positioning and cannot be aligned, and the parallelism of installation bolts on a tank body is poor. The self-positioning plastic vacuumtank has the beneficial effects that the mass is small, vacuum storage is good, the upper cover and the lower cover can be perfectly aligned and machined, installation is easy, and the tank can be conveniently used and popularized in an automobile enterprise.

Description

technical field [0001] The invention relates to the field of vacuum tanks used in automobile braking systems, in particular to a self-positioning plastic vacuum tank. Background technique [0002] For a long time, fuel vehicles have been the main force in the automotive industry. However, with the increasing environmental pollution and the gradual depletion of oil resources, new energy vehicles have become a new growth point in the auto market. Promoting the transition from high-pollution and high-emission traditional fuel vehicles to zero-emission or low-emission new energy vehicles is the only way for the automotive industry. Traditional fuel vehicles mainly use the rotation of the engine to continuously pump the vacuum to ensure a certain amount of brake power, and the operation method is more sensitive. In existing electric vehicles, the engine has been replaced by an electric motor, and the engine in a hybrid electric vehicle is not always working, and the electric mo...
