Description
Technical field
The present invention relates to brake caliper technical field, specifically a kind of eccentric pull-up structure formula hydraulic brake caliper.
Background technique
Caliper is fixed on knuckle by rack mounting apertures, can axially be occurred along guide pin and bracket relatively sliding
It is dynamic.Under the action of brake pressure, piston pushes piston side friction block, is pressed against piston side friction block on the disc brake rotor.Meanwhile
Brake pressure pushes caliper shell to move along guide pin, is pressed against fist side friction block also on the disc brake rotor, generates brake force.In
It is that brake disc two sides are clamped by friction block, and are braked.Brake disc tightens together with hub for vehicle wheel again, so wheel also stops
Rotation stop is dynamic.
With the progress of braking, friction block is constantly worn, and the gap between friction block and brake disc constantly increases, for dimension
The stability of this gap is held, caliper generally has the function of clearance automatic compensation.In braking, elasticity can occur for piston seal
Deformation；When loosening braking, sealing ring restores Zona transformans piston and returns to original position.After friction block is worn, between disc
Gap increases, and piston displacement increases when braking, and sealing ring and piston generate relative displacement in contact surface；After pressure release, after piston
The recovery deformation that the amount of shifting is still only dependent upon sealing ring keeps gap centainly to realize the compensation of friction block gap
Stability, to reach the stable state for theoretically braking mode.
As consumer market is higher and higher to the requirement in terms of automobile trip comfort and environmental protection and energy saving, in dragging for caliper
Stagnant, eccentric wear is screamed and is put forward new requirements to research staff in terms of tapping the noises such as abnormal sound.Develop it is low drag, low eccentric wear,
The caliper for improving noise situation is imperative.
Existing brake-caliper support is generally the push-pull configuration without outer beam, or the selection structure with outer beam.With outer beam
Selection structure, the function due to friction block backboard without drawing, so being forever a push mode, under this mode, due to friction block backboard
The torque that tup stress generates, can aggravate the offset of friction block center of effort, to be easy to cause eccentric wear, make to cause due to eccentric wear
Drag, the trend of noise etc. increases.Push-pull configuration without outer beam, the movement of external friction block is larger, so as to form push-pull configuration
Mode, this modality portions alleviate the offset of friction plate center of effort, alleviate eccentric wear to a certain extent, so that part drops
It is low dragged as caused by eccentric wear, rubbed partially, the influence of noise etc., but still remain friction surface pressure be unevenly distributed and ask
Topic causes to drag, rub partially, noise etc. can not further decrease.
Assembly method of the most caliper on axis is: one smaller above axis or be zero degree with horizontal line angle
Design.The influence being self-possessed using the friction block self weight of symmetrical positioning method, caliper shell assembly to gap is more obvious, together
When, the sealing ring, shell rebound after pressure release are larger to the impact equivalent of friction block, be easy to cause and tap abnormal sound and eccentric wear
Tendency.
Existing caliper generally uses large span, planar support or small span, single-point branch between external friction block and shell
It holds.Large span, planar support, although support is more stable, planar support forms clearance fit, easily causes abnormal sound noise.It is small across
Support that for large span, the support of small span is unstable, and single-point support also be easy to cause radial direction away from, single-point
It is unstable.
Therefore, it is necessary to design it is a kind of it is low drag, low eccentric wear, the eccentric pull-up structure formula hydraulic braking card for improving noise situation
Pincers.
Summary of the invention
The purpose of the present invention is overcome the deficiencies of the prior art and provide it is a kind of it is low drag, low eccentric wear, improve noise situation
