Description
Technical field
The utility model relates to battery-driven car motorcycle brake device and manufactures field, relates in particular to a kind of fender guard for battery-driven car motorcycle disc-brake.
Background technology
Battery-driven car, motor bike are that a kind of moving velocity is very fast, on the outskirts of a town, the vehicle that are commonly used in road, owing to travelling fast, flexibly, can walk in People's Bank of China, therefore higher to the sensitivity requirements of brake equipment.Brake equipment generally can be divided into shoe type and jaw type (disc brake) two kinds, has the advantages such as good braking effect, stable working, good heat dissipation, reliable operation, battery-driven car and motor bike widely use due to jaw type brake structure.
The caliper brake device of battery-driven car motor bike is made up of hydraulic oil pipe, brake clamp, brake disc (disk brake) etc., and its brake disc is fixed on lateral wheel, with rotation of wheel.During operation, when depressing brake pedal (or manual brake lever of holding with a firm grip), oil cylinder pushing friction lining is close to brake disc, the friction lining on both sides and the both ends of the surface of brake disc are fitted comprehensively, until brake disc is vised tightly, centre can produce very large friction drag, forces wheel to stop operating, and reaches the object of stopping or slowing down.
Because battery-driven car motorcycle brake dish operates with rotation of wheel, by bike through poor road surface, or when travelling in sleet sky, after thin sand and soil and rainwater etc. are involved in by wheel, easy adhesion on the disc brake rotor, cause disc brake sheet to rub ear-piercing abnormal sound, directly affect drag function, reduce safety shut-down effect, increase the dangerous situations such as brake plate loss.
Chinese patent CN201045054Y discloses following technology contents: for realizing providing one to block muddy water, greatly reduce the wearing and tearing of disk brake, again can be antitheft and structure is simple, motorcycle disc-brake protective hood easy for installation, it comprises the disk brake guard shield configuring with disc brake body and be connected, anti-theft column lock and the lower pump shielding plate of brake, the disk body of described disk brake guard shield is provided with pump breach under the brake of the lower pump of corresponding brake, the card of disk brake guard shield is provided with front shock absorber connection hole, anti-theft column lock mounting hole and lock core hole, the card center of disk brake guard shield is provided with front-axle hole.
Although above-mentioned patent can block muddy water, effect is general, still has muddy water and infiltrates.Meanwhile, disk brake entirety is covered not only that guard shield institute consumption material is more, cost is high, and if install not in place or travel in way and occur to loosen, can produce a very large impact brake equipment, cause safety misadventure.
Summary of the invention
It is simple, easy for installation that technical problem to be solved in the utility model is to provide a kind of structure, effectively can block the guard shield of battery-driven car motorcycle disc-brake of muddy water, grail.For this reason, the utility model is by the following technical solutions:
For a guard shield for battery-driven car motorcycle disc-brake, comprise disc cover plate, described cover plate is connected with wheel hub; The bottom surface of cover plate is annular arrangement, and decile offers mounting hole; The outside face of described cover plate side is provided with fin.When cover plate is arranged on battery-driven car motorcycle front-wheel, with hub support bar phase; When being arranged on trailing wheel, be connected with motor cover or strut bar.The mounting hole that cover plate bottom surface is offered, corresponding with the screwhole position on the strut bar of battery-driven car motor bike or motor cover, only need originally back out in order to fixing screw, sheathed for guard shield get on after be screwed again, without the need to extra spare and accessory parts, easy for installation.
On the basis adopting technique scheme, the utility model also can adopt following further technical scheme:
The fin of described cover plate side surface is the oblique setting in interval.This had both reinforced cover plate lateral stiffness, played reinforced rib effect, again admissible directed wind-force.Fin rotates along with guard shield, is conducive to, when battery-driven car motorcycle driving, the muddy water dropped on guard shield, sandstone etc. being thrown away better.
Described guard shield and wheel hub junction are provided with pad, make guard shield install more laminating with firm.
Described guard shield external diameter is greater than the diameter of brake disc, and guard shield can hold in it brake disc, makes the foreign matter such as muddy water, sandstone to enter disc brake apparatus, extends disc brake sheet operating cycles, keeps good braking effect.
Described guard shield can adopt ordinary rigid plastics to make, not only Portable durable, and with low cost.
Adopt the technical solution of the utility model, particularly guard shield according to the existing screw of battery-driven car motor bike, in the strut bar being fixedly mounted on wheel hub or motor cover, with vehicle wheel rotation.The muddy water taken up when vehicle travels, sandstone, because the effect of vehicle body mud guard can fall within guard shield, utilize the effect of centnifugal force and directed wind-force, the muddy water fallen, sandstone can better stop and throw away by oblique fin, keep the good braking effect being contained in disc brake apparatus in guard shield, improve travel safety.

Detailed description of the invention
By reference to the accompanying drawings, a kind of guard shield for battery-driven car motorcycle disc-brake that the utility model provides is described further.
Embodiment one, a kind of guard shield for battery-driven car motorcycle disc-brake that the utility model relates to, comprise disc cover plate, this cover plate is connected with wheel hub (motor cover).The bottom surface 1 of cover plate is in annular arrangement, and decile offers mounting hole 2, and the screw in the wheel hub of position and battery-driven car motor bike or motor cover is corresponding.The outside face of cover plate side 3 is provided with fin 4.
Embodiment two, in order to avoid silt to enter disc brake apparatus better, the fin 4 of cover plate side 3, in the oblique setting in interval, is conducive to the muddy water dropped on guard shield, sandstone etc. to throw away.The external diameter of guard shield is greater than the diameter of brake disc, and guard shield can hold in it brake disc, ensures that the foreign matter such as muddy water, sandstone can not enter disc brake apparatus.Other are identical with embodiment one.
Embodiment three, according to the configuration guard shield that the battery-driven car sold general on market manufactures, the base plate internal diameter of guard shield is 200 millimeters, and external diameter is 256 millimeters; Guard shield base plate offers four mounting holes, and each mounting hole diameter is 4 millimeters, and the distance of center circle of symmetrically arranged two mounting holes is from being 221.15 millimeters; The width of guard shield side plate is 37 millimeters, is provided with 12 pieces of fins above, and the length of every block fin is 35.5 millimeters; The thickness of cover plate is 6 millimeters.Other are identical with embodiment one.
Embodiment four, in order to guard shield is installed more firm, is provided with pad in the junction of guard shield and wheel hub (motor cover), makes more to fit between guard shield and wheel hub (motor cover).Other are identical with embodiment one.
