Description
Technical field
The present invention relates to a kind of brake, and in particular to a kind of brake suitable for the low-power vehicles.
Background technology
Existing Vehicular brake device typically has following several ways：Hub brake, the brake of rubber brake skin, mechanical disc brake, motor
The modes such as car disc brake are braked.In this several mode of braking, first two braking quality is poor, far can not meet that traffic safety will
Ask；Mechanical disc brake can not compensate automatically after friction disc wear, cause very big potential safety hazard；And use motorcycle hydraulic brake
Device obvious cost for bicycle, small displacement power assist vehicle is too high, and inapplicable (without so big brake force), so as to make
Into the wasting of resources.
Some low-power brake for vehicle still use traditional common lock and caliper brake, its brake rubber block short life, need
Often change, directly wear rim, reduce rim intensity and surface etch resistant properties, influenceed by external environmental factor it is big etc. a variety of
Drawback.
The content of the invention
To solve the above problems, the present invention provides a kind of brake suitable for the low-power vehicles, safe and reliable, event
Barrier rate is low, service life length.
To achieve these goals, a kind of brake suitable for the low-power vehicles of the invention, is by brake lever, restrictor bar
Composition, the lower end of described restrictor bar are connected with one end of rocking arm, and the other end of rocking arm withstands the piston rod of master cylinder, and master cylinder passes through system
Hydrodynamic pipe communicates with the wheel cylinder halfbody being placed on support, relative to the another of wheel cylinder oil pocket on the pump housing of described wheel cylinder halfbody
Side is provided with mutually isolated oil sump chamber and plunger shaft, and the piston component with return mechanism, piston are provided with plunger shaft
It is exposed at outside plunger shaft to piston rod end dynamic sealing in component, oil sump is provided with nearly return end and adjacent piston head in plunger shaft
Chamber intercommunicating pore connects with oil sump chamber, is connected at remote return end provided with wheel cylinder oil pocket intercommunicating pore with wheel cylinder oil pocket, described oil sump
Chamber, plunger shaft, piston component and intercommunicating pore form the startup master cylinder with wheel cylinder halfbody one.
The pump housing front end of wheel cylinder halfbody has pincerlike arm, and piston is opened provided with oil sealing, piston between the two loaded in the pump housing
The liner plate of the provided inner attrition piece in mouth end is in contact, and on pincerlike arm of the outside friction disc loaded on the pump housing, liner plate is connected with support,
Support casing is loaded on vehicle frame loaded on the pump housing by deck.
The brake is provided with two wheel cylinder halfbodies, and opposed type is set, and Packed connection is set between two wheel cylinder oil pockets
Oil duct, form opposed type braking operation mechanism.
Start master cylinder and be directly designed to an entirety with the body portion of brake cylinder half, compared with prior art, lack a system
Dynamic oil pipe, structure closely, safety and production cost it is relatively low, the setting of the pulling cable connecting mechanism on piston rod outer end head in addition
Be easy to current electric bicycle, small displacement power assist vehicle brake handle on brake cable match, without making big repacking, very
It is easily installed and is used on electric bicycle, small displacement power assist vehicle.Piston move, withstand liner plate, inner attrition piece, at the same time by
It is placed in the pump housing in support, therefore the pump housing while the power by one with piston opposite direction, then pincerlike arm is driven together with outside friction disc
Moved to brake disc lateral surface compaction direction, and then brake disc is stopped operating, when braking finishes, brake force is released, and master cylinder is lived
Plug is set back in the presence of return spring, and brake disc is resumed work state therewith.Braking moment is big, effect is good, steadily may be used
Lean on, slow down or stop arbitrarily, operation is flexible, does not damage rim, service life length, is influenceed the advantages that small by external environmental factor.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention.
