Description
Technical field
The present invention relates to the automobile braking device field, especially, is a kind of non-maintaining braking automobile structure.
Background technique
Braking device is by producing friction between brake block and wheel hub or the disc, and the kinetic energy during with automobile running is transformed into thermal energy consumption and falls 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 is at two semi-circular brake blocks of wheel hub the inside installing, and utilization " lever principle " promotion brake block makes brake block contact with the wheel hub inner face and rubs.The mode of action of drum brakes: briefly, drum brakes is exactly to utilize static brake block in the brake drum, and the brake drum along with vehicle wheel rotation of going to rub is to produce the turn a wheel braking device of Speed Reduction of frictional force.Disk type brake is with static brake disc, clamps braking disc along with tyre rotation to produce frictional force, and the speed that turns a wheel is with low braking device.
No matter make " drum brakes " still " disk type brake " all adopt brake block braking because rubbing action, brake block can be worn gradually, the brake block that cost is lower in general weares and teares sooner.Will in time change brake block after friction material uses, otherwise steel plate will contact directly with brake disc, finally can lose braking effect and damage brake disc.Simultaneously, 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 that basically is exactly high temperature causes.
Summary of the invention
In order to address the above problem, the object of the present invention is to provide a kind of non-maintaining brake structure, in the time of this non-maintaining brake structure positive braking, need not renewal part and also do not produce harmful matter.

Fig. 2 is the embodiment's two of this non-maintaining brake structure structural representation.
Embodiment
The present invention is further described below in conjunction with drawings and Examples:
Embodiment one:
Consult Fig. 1, in the present embodiment, this non-maintaining brake structure comprises the transmission shaft 110 that is 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, the center that described braking plate 200 is dish type and 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 disc side of described braking plate 200 is provided with the telescoping member 210 that the described braking plate 200 of control stretches vertically, upwards be provided with the elasticity covering 300 in space between two described braking plates 200 of sealing the week of described two braking plates 200, be full of low melting point working medium in the space between described two described braking plates 200, in described braking plate 200 and the described brake disc 100 at least one of them inside be provided with the refrigeration member.
Above-mentioned non-maintaining brake structure, described low melting point working medium is low-melting alloy.
Low-melting alloy refers to that fusing point is lower than the low melting alloy of 232 ℃ (fusing points of Sn); Usually formed by low melting metal elements such as Bi, Sn, Pb, In.Low-melting alloy often is used as scolder widely, and the temperature-sensitive assemblies such as the safety fuse cutout in the devices such as electrical equipment, steam, fire-fighting, fire alarm, fus, is the low-melting alloy new material that a class has much development potentiality.Low-melting alloy comprises: 47 ℃ of low-melting alloys, 50 ℃ of low-melting alloys, 55 ℃ of low-melting alloys, 60 ℃ of low-melting alloys, 70 ℃ of low-melting alloys, 92 ℃ of low-melting alloys, 120 ℃ of low-melting alloys, 138 ℃ of low-melting alloys, 180 ℃ of low-melting alloys.
