Just the operation principle of the laborsaving hand brake device of the present invention is described in detail below.
When need to pull the hand brake parking when, the grip part 11 of handle 1 need to be lifted upwards, at this moment, second piston bar 221 drives the
Two pistons 222 are moved downward and are pressed to hydraulic oil, push the hydraulic oil at the top of the second hydraulic cavities 2b to the second hydraulic cavities 2b
Bottom makes third piston 232 be moved downward under the promotion of hydraulic oil, pushes the hydraulic oil of the first bottoms hydraulic cavities 2a to first
The top of hydraulic cavities 2a, meanwhile, First piston bar 211 drives first piston 212 to move upwards, and is pushed up to the first hydraulic cavities 2a is flowed to
The hydraulic oil in portion concedes space.In the process, third piston 232 drives third piston rod 231 to move downward, and is lived by third
Stopper rod 231 drives the cable wire 6 being connected on annulus 5 to move downward, and makes the tight wheel of the braking caliper device being connected with cable wire 6 brake.
Meanwhile sealing block 8 is moved downward also with third piston rod 231, therefore spring 7 is stretched.
It lets go in a flash, the grip part 11 of fixed handle 1 need to be pressed downwards, at this moment, First piston bar 211 drives first piston 212
It moves downward and gives hydraulic oil pressure, the hydraulic oil at the top of the first hydraulic cavities 2a is pushed to the bottom of the first hydraulic cavities 2a, make the
Three pistons 232 move right under the promotion of hydraulic oil, push the hydraulic oil of the second bottoms hydraulic cavities 2b to second hydraulic cavities 2b
Top, meanwhile, second piston bar 221 drive second piston 222 move upwards, to the hydraulic pressure flowed at the top of the second hydraulic cavities 2b
Oil concedes space.In the process, third piston 232 drives third piston rod 231 to move right, to making cable wire 6 loosen
Releasing of brake caliper arrangement.In addition, during third piston rod 231 moves right, the spring 7 being stretched originally can also produce
Raw restoring force, pulls sealing block 8 to move right, to promote third piston rod 231 to move right, the operation of release parking brake is made to become
It obtains more effortless.
To sum up, in the present invention, either pull the hand brake still RELEASE PARKINGBRAKE, in hydraulic cylinder 2 all as the hydraulic oil in force source
It needs to flow to the larger part of diameter of cylinder from the smaller part of diameter of cylinder, and 2 pressure then remains unchanged in hydraulic cylinder, such as
This, pulling the hand brake and can increase the hydraulic coupling acted on third piston 232 during RELEASE PARKINGBRAKE, and lives with third
In the case that active force that the connected braking caliper devices of plug 232 need is constant, it can reduce and need to act on parking brake handle
Active force, to reach labour-saving purpose.And the laborsaving hand brake device of the present invention is simple in structure, convenient and practical, operating characteristics
It is good.
In addition, in the present embodiment, spring 7 and block 9 are provided in third cylinder body 23, certainly in other embodiment
In, spring 7 and block 9 can not also be set, third cylinder body 23 is directly sealed by sealing block 8, naturally it is also possible to pass through it
He seals form.
The above is merely preferred embodiments of the present invention, be not intended to limit the invention, it is all the present invention spirit and
All any modification, equivalent and improvement made by within principle etc., should all be included in the protection scope of the present invention.
