Description
Technical field
The present invention relates to automobile braking device field, especially, is a kind of non-maintaining braking automobile structure.
Background technique
Braking device produces friction by between brake block and wheel hub or disc, and becomes thermal energy consumption to fall kinetic energy during automobile running in the process of friction.Common braking device has " drum brakes " and " disk type brake " two kinds of patterns, their basic characteristic is as follows: drum brakes installs two semi-circular brake blocks inside wheel hub, utilizes " lever principle " to promote brake block and makes brake block and wheel hub inner faces contact and rub.The mode of action of drum brakes: briefly, drum brakes is exactly utilize brake block static in brake drum, removes the brake drum rubbed along with vehicle wheel rotation, to produce the braking device that the frictional force speed that turns a wheel reduces.Disk type brake is with static brake disc, and clamp along with the braking disc of tyre rotation is to produce frictional force, the speed that turns a wheel is by low braking device.
No matter make " drum brakes " or " disk type brake " all to adopt brake block to brake, due to rubbing action, brake block can be worn gradually, and the brake block that cost is lower in general weares and teares faster.Will change brake block in time after friction material uses, otherwise steel plate directly will contact with brake disc, finally can lose braking effect and damage brake disc.Meanwhile, during brake, the wearing and tearing of brake block can produce the powder of high temperature, often can observe burning on some wheel hubs, and the powder corrosion being substantially exactly high temperature causes.
Summary of the invention

Embodiment
Below in conjunction with drawings and Examples, the present invention is further described:
Embodiment one:
Consult Fig. 1, in the present embodiment, this maintenance-free brake structure comprises the transmission shaft 110 be connected with wheel hub power, brake disc 100 and braking plate 200, described transmission shaft 110 is fixed on the axis of described brake disc 100, described braking plate 200 is dish type and the center of described braking plate 200 is provided with the aperture with described transmission shaft 110 air-tight fit, the both sides of described brake disc 100 are coaxially arranged with described braking plate 200, the non-brake dish side of described braking plate 200 is provided with the telescoping member 210 controlling described braking plate 200 and stretch vertically, the circumference of described two panels braking plate 200 is provided with the elasticity covering 300 in space between braking plate 200 described in closed two panels, low melting point working medium is full of in space between braking plate 200 described in described two panels, in described braking plate 200 and described brake disc 100, at least one of them inside is provided with refrigeration component.
Above-mentioned maintenance-free brake structure, described low melting point working medium is low-melting alloy.
Low-melting alloy, refers to the low melting alloy of fusing point lower than 232 DEG C (fusing points of Sn); Usually be made up of low melting metal elements such as Bi, Sn, Pb, In.Low-melting alloy is often used as solder widely, and the temperature-sensitive assembly such as safety fuse cutout, fus in the device such as electrical equipment, steam, fire-fighting, fire alarm, is the quite potential low-melting alloy new material of a class.Low-melting alloy comprises: 47 DEG C of low-melting alloys, 50 DEG C of low-melting alloys, 55 DEG C of low-melting alloys, 60 DEG C of low-melting alloys, 70 DEG C of low-melting alloys, 92 DEG C of low-melting alloys, 120 DEG C of low-melting alloys, 138 DEG C of low-melting alloys, 180 DEG C of low-melting alloys.
In the present embodiment, select the low-melting alloy of 47 DEG C, due to comparatively close to normal temperature, therefore, under the state of non-brake, the dissolving temperature maintaining low-melting alloy makes it keep liquid state to be easier to.
Above-mentioned maintenance-free brake structure, described refrigeration component is semiconductor refrigerating sheet, and semiconductor refrigerating sheet has minimum volume, makes it be easy to install.
