Detailed Description
The following describes the embodiments of the present invention in detail. It is to be understood that the description of the embodiments herein is for purposes of illustration and explanation only and is not intended to limit the invention. In the present invention, the use of the terms of orientation such as "upper and lower" in the case where no description is made to the contrary generally means the orientation in the assembled and used state. "inner and outer" refer to the inner and outer contours of the respective component itself.
In order to realize the above object, the utility model discloses an aspect provides an additional booster unit of car vacuum booster, as shown in fig. 1, car vacuum booster's additional booster unit includes vacuum booster casing 1, general casing 1 divide into preceding cavity 3 and back cavity 4 and can be in the air chamber baffle 2 that casing 1 removed, be equipped with brake master cylinder push rod 6 in the preceding cavity 3, air chamber baffle 2 is close to one side of preceding cavity 3 is equipped with ferromagnetic metal, preceding cavity 3 is kept away from one side of ferromagnetic metal is provided with electro-magnet 5.
Compared with the existing vacuum booster, the additional boosting device of the automobile vacuum booster can save more labor when a driver brakes the automobile, and can obtain better braking effect by treading the brake pedal with the same force.
Particularly, foretell technical scheme is add an additional booster unit on current car vacuum booster, is in vacuum booster's vacuum cavity promptly add one set of electro-magnet 5 in the preceding cavity 3, and be close to at air chamber baffle 2 one side of preceding cavity 3 is equipped with ferromagnetic metal, through such setting, except getting into in the back cavity 4 when the driver tramples brake pedal and producing the power that the pressure differential formed with the interior vacuum of preceding cavity 3, still have electro-magnet 5 to air chamber baffle 2 appeal, can increase air chamber baffle 2 is right the thrust of brake master cylinder push rod 6 improves braking efficiency, and reduces the reaction force to brake pedal, can make driver's laborsaving more when braking.
In an alternative embodiment, the electromagnet 5 is disposed coaxially with the brake master cylinder push rod 6, and a passage through which the brake master cylinder push rod 6 passes is disposed on the electromagnet 5.
Through the coaxial arrangement of the electromagnet 5 and the brake master cylinder push rod 6, the electromagnet 5 can enable the ferromagnetic metal attraction center point on the air chamber partition plate 2 to coincide with the brake master cylinder push rod 6, and when the electromagnet 5 generates attraction force on the ferromagnetic metal, the air chamber partition plate 2 can intensively act on the brake master cylinder push rod 6, so that energy loss is reduced, and efficiency is increased.
In an alternative embodiment, the auxiliary booster of the vehicle vacuum booster further comprises a sensing device disposed on the brake pedal, and a controller connected to the sensing device and the electromagnet 5 through wires. The controller can be a PLC controller or an ECU.
The additional booster device of the automobile vacuum booster is more intelligent through the arrangement, and the additional booster device of the automobile vacuum booster is controlled to be started or closed by detecting the change of the brake pedal through the sensing device. The power consumption of the electromagnet 5 is switched on or off by transmitting a signal to the controller, so that the additional power assisting device of the automobile vacuum booster can be powered off timely when not used, and the purposes of energy conservation and environmental protection are achieved.
