A kind of device reducing automotive hub windage
Technical field
The invention belongs to automotive fields, are a kind of auxiliary devices reducing automotive hub windage specifically.
Background technology
Automobile friction of brake block and brake disc in brake makes to have accumulated a large amount of heat on brake disc, and brake disc needs to the greatest extent
These fast heats distribute, and not so the brake disc in the condition of high temperature is highly susceptible to damage for a long time, and then influences vapour
The braking effect of vehicle.
Wheel hub is an important component of auto parts and components, has mutual corresponding bolt hole on wheel hub and brake disc,
Together with so that wheel hub is bolted with brake disc, wheel hub generally on the market has the hollow out of large area, stops in automobile
The wheel hub of hollow out contributes to air-flow by brake disc when vehicle, radiates to brake disc, reduces the temperature of brake disc.But it is logical to depend merely on nature
The radiating rate of wind is slow, and when need not brake in vehicle traveling process, and the hollow out of wheel hub will give the traveling band of automobile
Carry out resistance, and the travel speed of automobile is faster, the resistance brought by wheel hub is bigger, and automobile overcomes the energy that resistance is consumed
It is more.Especially when automobile on a highway when driving, the travel speed of automobile is fast, and the number of brake is few, the wheel of hollow out
The shortcomings that hub is brought is just more prominent.There is the automobile of some brands to match a dismountable totally enclosed lid to wheel hub,
In running car into loading onto lid before expressway, with energy saving, but dismounting takes time and effort in this way, and the lid after unloading also needs
It wants space to store, uses very inconvenient.
Invention content
Purpose of the present invention is to be intended to provide a kind of auxiliary device reducing automotive hub windage, make wheel hub in the brake of automobile
Hull temperature is low when need not radiate without ventilative engraved structure, reduces the running resistance of automobile, and in the brake of automobile
With ventilative engraved structure when disk temperature height needs to radiate, accelerate the radiating rate of brake disc.
To realize the above-mentioned technical purpose, the technical solution adopted by the present invention is as follows:
A kind of auxiliary device reducing automotive hub windage, includes the wheel hub and brake disc of automobile, and the surface of the wheel hub is radial
It is evenly equipped at least three pieces wheel hub blade, the both ends of the wheel hub blade are respectively and fixedly provided with a swingle, and the swingle is mounted on wheel hub
On end cap in corresponding rotating hole, under outer force effect, wheel hub blade can rotate in rotating hole makes wheel hub blade be in closing shape
State or opening state;The wheel hub vane hinge is in one end of compression bar;The other end of the compression bar and the base surface of pressing plate are solid
Fixed connection.
The base surface of the pressing plate is fixedly connected with one end of mandril, and the other end of the mandril and the top plate face of movable plate connect
It connects;The movable plate is mounted on by piston seal in the inner cavity of gas-liquid conversion cylinder, and movable plate can be in gas-liquid under outer force effect
It is moved up and down in the inner cavity of conversion cylinder, the liquid converted for gas-liquid is provided in the inner cavity of the gas-liquid conversion cylinder;In wheel hub
Centre of surface position be provided with the mounting hole to match with gas-liquid conversion cylinder, the gas-liquid conversion cylinder passes through mounting hole and brake disc
It is fixedly connected.
The present invention due to above-mentioned design advantageously:Brake disc temperature is low need not radiate when, wheel hub blade
It is closed, has sealed the hollow out on wheel hub, reduce the running resistance of automobile;When the temperature height of brake disc needs to radiate
When, among the heat transfer to gas-liquid conversion cylinder of brake disc, so that gas-liquid conversion object is moved by thermal evaporation promotions mandril, by thermal energy turn
Kinetic energy has been turned to, the dissipation of heat is accelerated, on the other hand, the movement of mobile mandril energy band dynamic pressure plate, and then by wheel hub blade
It opens, so that brake disc is divulged information, accelerate the radiating rate of brake disc.
