Description
Technical field
This utility model belongs to vehicle brake technology field, is specifically related to a kind of brake block from flat
Weighing apparatus formula brake gear.
Background technology
Hub is braked due to reliability and powerful brake force so that it is be the most still arranged in many
In vehicle, such as heavy goods vehicle, motorcycle, electric motor car.Hub brake is by device by hydraulic pressure
In brake hubs, there is brake block toward extrapolation, make brake block and along with in the brake hubs of vehicle wheel rotation
Face occurs friction to produce the effect of skidding.
But existing hub is braked in braking procedure, and its brake block can produce and move up and down,
Making brake block is to keep balance in braking.Such as, Publication No. CN203868187U
Chinese patent disclose a kind of novel hub and stop, mainly by housing, brake block, rocking arm wheel, multiple
Position spring composition, rocking arm wheel is arranged on housing, is provided with back-moving spring, brake block in brake block
Being arranged on housing by back-moving spring, described hub is stopped at least provided with three identical brakes
Sheet, is provided with movable rotor in the inside of every two panels brake block abutting end, and movable rotor is taken turns with rocking arm
On lobe contact, reduce span between the both ends of each brake block, effectively drop
The deformation of brake block itself in low braking procedure, improves the life-span of brake block.But due to this skill
Art scheme is to use cam rocker arm to be connected to brake block, by bracing wire or pull bar stress, therefore exists
In brake process, dynamics is uneven, and braking effect is unstable.Brake block is can not in braking simultaneously
Keep balance, and then reduce brake reliability.
In order to improve the insensitivity of brake, occur in that various water brake system at present
Dynamic device, such as, the Chinese patent of Publication No. CN201434030Y discloses a kind of motorcycle
Brake disc, including brake hubs, is provided with the ungulate upper and lower brake block of two symmetries in brake hubs,
The other end of upper and lower brake block is fixed on brake disc, is connected by return spring, upper and lower
Brake block outer side edges can contact with brake hubs, brake pump and bleeder screw and oil-feed screw phase
Logical.Although this technical scheme have employed hydraulic principle so that brake is formed little, to a certain degree
On improve the security performance of brake.But owing to upper and lower brake block is not provided with any fixing
Device, therefore, upper and lower brake block moves up and down former so can the generation of braking, it is impossible to keep flat
Weighing apparatus, thus affect braking reliability.
For another example, the Chinese patent being disclosed as CN203739873U discloses a kind of automobile liquid compacting
Dynamic device, its structure is brake pedal linkage push rod, and push rod connects the master cylinder in master cylinder and lives
Plug, master cylinder connected pipes, oil pipe connects brake cylinder, and brake cylinder is arranged on the braking end
On plate, brake cylinder is in series with secondary wheel cylinder, and secondary wheel cylinder is arranged on bottom back-plate, secondary
Being provided with secondary piston in level wheel cylinder, secondary piston top is provided with friction head, and friction head is close
Brake drum inwall, is provided with spring base bottom back-plate, the back-moving spring that spring base is arranged
Boss in apical grafting secondary piston.By bifurcated parallel pipeline between brake cylinder and secondary wheel cylinder
Connect, the axis of furcation pile warp back-plate.This hydraulic vehicle brake system is at two-piece type
Drum increases on the basis of stopping and arranges a secondary wheel cylinder and increase the setting of a friction head, makes drum
Stop mechanism expand, skidding effect is further promoted.But, owing to left and right is braked
The lower end of hoof is to support pin by left and right to be respectively hinged on back-plate, therefore at braking procedure
In, left and right brake-shoe can be flared out and sliding downwards, and As time goes on, spring is being grown
Phase is deformed by under the effect of pulling force, thus causes left and right brake-shoe can not automatically reset and lose
Go balance, and then shadow brake safe performance.
In sum, existing bulging braking device is owing to being directly brake block to be arranged on support
On, it is not provided with any fixing device, when brake block is braked, mostly there is brake block can not
Keep the deficiency of balance, the most how to make brake block remain poised state when braking, with
Improve the stability of skidding, be current vehicle brake technology field problem demanding prompt solution.
Utility model content
For solving the problems referred to above, the invention provides a kind of brake block self-balancing type brake gear.
This device, by arranging fixed support, makes brake block not produce in braking procedure and moves up and down,
Make brake block remain poised state, and then improve braking reliability.
The present invention is achieved by following technical solution.
A kind of brake block self-balancing type brake gear, including housing, right brake block, left brake block
And hydraulic pump, described hydraulic pump is arranged on housing upper, right brake block and left brake by bolt
Sheet is respectively symmetrically and is arranged on enclosure interior left and right side, described right brake block and left brake block
Lower end is hinged by swivel pin, and the upper end of right brake block is connected with oil-out B by pipeline, left
The upper end of brake block is connected with oil-out A by pipeline, described right brake block and left brake block
