Abstract
The utility model relates to a kind of vacuum booster with radial air inlet structure, belongs to automobile brake technical field.Dust boot one end and rear housing interference fit, the other end and valve rod interference fit, foam filter elements one and valve body interference fit, rubber valve seat and valve body interference fit, air valve base contacts cooperation with rubber valve seat, there is 8-10 radial air inlet hole dust boot side, along interference assembling foam filter elements two on the position of dust boot induction opening.The utility model has the advantage of: novel structure is simple, the inflow noise value of servo-unit is little.Driver and crew can not produce bad sensation, improve driver comfort.
Description
Technical field
The utility model belongs to automobile brake technical field, especially the improvement to automobile vacuum booster.
Background technology
Vacuum booster is the brake power assist unit in light, car brake system, is the critical component in brake system of car.Its principle of work is the vacuum producing while utilizing engine petrol work, or the vacuum that produces of the vacuum pump that installs additional of diesel motor, when chaufeur depresses brake pedal, the thrust of borrowing the different difference of pressure of two epitrochoidal chambers in vacuum booster to produce, by design proportion, amplify brake pedal force and promote brake master cylinder piston, braking liquid in compression brake master cylinder produces hydraulic pressure, and is delivered to wheel drg and makes brake shoe brake cheek contact and then produce friction drag control car retardation or braking with wheel nave.
Conventional vacuum booster air intake structure as shown in Figure 1.Dust boot 1 ' one end and rear housing 6 ' interference fit, the other end and valve rod 7 ' interference fit, foam filter elements 2 ' together with valve body 3 ' interference fit, rubber valve seat 4 ' with valve body 3 interference fit, air valve base 5 ' with rubber valve seat 4 ' contact cooperation, dust boot 1 ' end have axial admission hole 8 ', induction opening 8 ' shape and quantity because of the dimensions of servo-unit different.When servo-unit is worked, air is by the induction opening 8 on dust boot ' enter, then through foam filter elements 2 ' enter into servo-unit inside.
The air inlet mode of conventional vacuum booster is axial admission, when vacuum booster is worked, needs a large amount of air from the external world, to enter into servo-unit inside.The inflow noise of this kind of intake method is larger, although the performance of vacuum booster is not greatly affected, chaufeur is relatively disliked inflow noise, causes driver comfort to reduce.
Summary of the invention
The utility model provides a kind of vacuum booster with radial air inlet structure, and to solve conventional vacuum booster axial admission, inflow noise is larger, the problem that driver comfort reduces.
The technical solution of the utility model is: dust boot one end and rear housing interference fit, the other end and valve rod interference fit, foam filter elements one and valve body interference fit, rubber valve seat and valve body interference fit, air valve base contacts cooperation with rubber valve seat, there is 8-10 radial air inlet hole dust boot side, along interference assembling foam filter elements two on the position of dust boot induction opening.
The utility model has the advantage of: novel structure is simple, the inflow noise value of servo-unit is little.Driver and crew can not produce bad sensation, improve driver comfort.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model background technology;
Fig. 2 is structural representation of the present utility model.
The specific embodiment
Dust boot 1 one end and rear housing 6 interference fit, the other end and valve rod 8 interference fit, foam filter elements 1 and valve body 3 interference fit, rubber valve seat 4 and valve body 3 interference fit, air valve base 5 contacts cooperation with rubber valve seat 4, there is 8-10 radial air inlet hole 9 dust boot 1 side, along interference assembling foam filter elements 27 on the position of dust boot 1 induction opening.
Induction opening shape and quantity because of the dimensions of servo-unit different, when servo-unit is worked, air first passes through foam filter elements two, is entered, then enter into servo-unit inside through foam filter elements one by the radial air inlet hole on dust boot.
Claims (1)
