Abstract
The utility model relates to a rotary vane for an automotive vacuum pump. The rotary vane is characterized in that a rotor is eccentrically arranged in a shell, two L-shaped rotary vane bodies are arranged in a rotor groove, and after the rotor rotates, the circular arc ends of the rotary vane bodies are always clung to the wall of the shell under the effect of centrifugal force. Due to rectangular grooves in the inner sides of the rotary vane bodies, the weight of the rotary vane bodies is reduced, so that the inertia torque is reduced, and the power consumption is also reduced.
Description
Technical field
The utility model relates to a kind of blade for automobile vacuum pump.
Background technique
Vehicle-mounted vacuum pump, its Main Function is for the vacuum booster unit of brake system of car provides vacuum, to alleviate the fatigue strength of driver, and ensures that brake system of car can provide enough braking force.Vehicle-mounted vacuum pump is by the rotation of the rotor in vacuum pump and blade, and the air that suction port is sucked is compressed at pump housing inner chamber, discharges from air outlet, and therefore the pump housing, rotor and this three's of blade structure is the key of vacuum pump performance.
Summary of the invention
The utility model provides a kind of blade for automobile vacuum pump, particularly has the blade of less consumed power, and concrete technological scheme is as follows:
Blade entirety presents L shaped shape, and one end of blade is provided with circular arc.
There is the groove of the rectangle of several proper alignment the inner side of blade.
The utility model, by changing the structure of blade, has reduced the weight of blade, thereby has reduced inertia torque, has also therefore reduced power consumpiton.
Brief description of the drawings
Below in conjunction with accompanying drawing, the utility model is further described:
Fig. 1 is the work schematic diagram of blade.
Fig. 2 is the schematic diagram of blade in the utility model.
Wherein, 1, blade 2, rotor 3, housing 4, circular arc 5, groove
Concrete mode of execution
Rotor is housed prejudicially in housing, the blade of two L shaped shapes is housed in rotor, after rotor rotates, the arc end of blade is close to all the time shell body wall under the effect of centrifugal force.The rectangular recess of blade inner side has reduced the weight of blade, thereby has reduced inertia torque, has also therefore reduced power consumpiton.
