Description
Technical field
The present invention relates to a kind of brake system, particularly one many friction plates brake system, belong to vehicle body fittings field.
Background technique
Brake system is divided into disc type, drum-type two kinds, and the mode of action of disk type brake is that clamp arrange brake block, and phase mutual friction between the brake disc that during brake, brake block and wheel link, until wheel stops operating.Have in disk type brake and punch on brake disc, utilize and travel the natural wind that brings and reach heat radiation object.The mode of action of drum brakes is that basin shape brake drum is connected with wheel, and semi-moon shaped brake block upwards jack-up under the effect of connecting rod, phase mutual friction, makes wheel stall.Disk type brake can coordinate with hydraulic system easily, is used for high-grade car; And the cost of drum brakes is lower, absolute brake Li Genggao, more utilization is with in the trailing wheel or lorry of pony car.But, these brake system are all generally act on the brake disc that is connected with automotive hub, no matter be disc type or drum-type, bicycle hub for vehicle wheel only have a brake disc or brake drum, two panels brake block, during brake, the strength acted on brake disc or brake drum is quite large, and brake disc or brake drum are mostly utilize ironcasting to form, resemble drum brakes drum used on high capacity waggon, because gravity is large, frictional force is large, usually there will be brake drum car drum temperature that is damaged or that cause because of frictional force too high is the situation of brake disc heating distortion, What is more because the damage of brake drum, because drum type braking device also cannot install antilock device, even cause traffic accident, cause serious economy or life safety, so, in order to reduce the temperature of brake drum, have driver to water on brake drum to cool brake drum, although disc type is comparatively safe, but, can not for heavy vehicle, because brake block is few, lifting surface area on brake disc is limited, brake strength is less, in addition, owing to only there being a brake disc, when braking too fast, shake or the jumping phenomena of vehicle can be caused, brake to have too slowly and be difficult to tackle urgency, how to overcome these phenomenons, it is the suggestion thing that researcher is concerned about.
Summary of the invention
The phenomenon such as easily cause shake for brake drum easily damaged or distortion, brake disc or beat, the invention provides a kind of many friction plates brake system, its objective is to reduce the strength be applied on single brake disc, accelerate the heat dissipation rate of brake disc, reduce the shake in brake process or jumping phenomena.
Technological scheme of the present invention is: a kind of many friction plates brake system, comprise semiaxis, brake drum is directly or indirectly fixedly connected with semiaxis, semiaxis periphery is provided with back axle housing, directly or indirectly be rotationally connected between back axle housing and brake drum, perpendicular to axial directionly in brake drum Moving plate and quiet dish are arranged alternately, described Moving plate is circumferentially arranged at intervals with breach, described brake drum periphery is provided with strip opening vertically, Moving plate circumferentially between breach the raised area slide axially and be arranged in brake drum perimeter strip opening, Moving plate central part arranges porose, gap is had between described hole and back axle housing, back axle housing periphery in described brake drum is splined shaft, portion of described quiet disk center is provided with the internal spline that to match with back axle housing periphery splined shaft, quiet dish is by being slidably connected between internal spline and back axle housing, the quiet card relative with Moving plate is provided with friction plate, the quiet dish being positioned at semiaxis power side end is connected with drive unit, the quiet dish in end away from drive unit is fixedly connected on back axle housing, during driving, semiaxis drives brake drum to rotate together with Moving plate, quiet dish does not rotate, during brake, the quiet dish of drive unit drive end makes except moving near realizing brake away from the used quiet dish except the quiet dish in end of drive unit and Moving plate along splined shaft, brake drum is fixedly connected with by supporting sleeve with semiaxis, be rotationally connected between back axle housing and supporting sleeve, described back axle housing is vertically connected with disk, disk is arranged at outside brake drum opening side, described drive unit is arranged on disk, described drive unit is at least two covers, each drive unit is uniformly distributed along disk, described drive unit is oil hydraulic cylinder, described Moving plate breach circumferentially has two at least, described each notch geometry is identical, circumferentially be uniformly distributed, brake drum perimeter strip opening number and breach number match, described Moving plate breach is circumferentially no less than four, brake drum perimeter strip opening number and breach number match, described quiet dish and Moving plate at least respectively arrange two.
The good effect that the present invention brings is, owing to being provided with multiple Moving plate and corresponding quiet dish, reduce the friction pressure on each brake disc, reduce the vehicle brought that brakes to beat or jitter phenomenon, improve the stopping power of brake system, reduce the required strength of brake, because there is certain gap between brake system Moving plate and quiet dish, improve the heat dissipation potential of brake disc, owing to being provided with multiple brake block, there is multi-level brake insurance, ensure that the safe and reliable of braking system.
