Abstract
The invention discloses a parking and driving combined wet brake which comprises a plurality of movable friction sheets, a plurality of static friction sheets, a plurality of springs, a brake cylinder, a brake piston, a brake shell and a brake cylinder cover, wherein the movable friction sheets and the static friction sheets are arranged at intervals in parallel, an inner hole of the brake shell is machined into a tooth-shaped spline, the excircle of each static friction sheet is also machined into a tooth-shaped spline, the static friction sheets are arranged on the tooth-shaped spline in the brake shell to form a whole; tooth-shaped spline inner holes of the movable friction sheets are connected with an external spline on a drive bridge half axle to form a whole, the head part of a piston rod of the brake cylinder supports against the movable friction sheets, and a rodless cavity of the brake cylinder is internally provided with a plurality of bearing springs which act on the brake piston. A multiple-movable and static friction sheet combined form is adopted in the invention, the brake moment is large; the driving brake is integrated with the parking braking organically, thus the parking and driving combined wet brake is simplified, braking safety and reliability of vehicles are enhanced, service life of brake parts is effectively prolonged, and braking effect is further improved; and the parking and driving combined wet brake has high reliability.
Description
Technical field
The present invention relates to a kind of break, particularly various vehicles make uses break.
Background technique
Existing vehicle braked device system mostly is divided into parking brake and two braking device of service brake, and when vehicle was out of service, by parking brake work, vehicle was in static braking state.The parking brake of vehicle mostly is installed in driving wheel main transmission input shaft side, has only driving wheel place braking state when therefore stopping, and non-driving wheel place free state, the braking moment that vehicle obtained is limited.In case of emergency, when the ramp heavy duty was stopped, the landslide phenomenon happened occasionally as vehicle.
During the vehicle driving running state, its braking work is finished by service brake, service brake mainly contains patterns such as shoe type, caliper disc brake at present, and these breaks are subjected to its structure influence, and what the braking working surface had directly exposes, and what have can't seal, foreign material such as the water on the travel face, sandstone, earth, dust enter working surface, make its braking effect variation, especially under bad working environments such as mine, down-hole, formed huge potential safety hazard especially; Moreover be exactly the power of these breaks from oil pressure or air pressure, the deficiency of retardation pressure can have a strong impact on braking effect.If brake oil, tracheal rupture take place, then brake total failure, abroad the incident that therefore problem is recalled relevant vehicle vehicle in the world also appearred in some well-known quality automakers.
Summary of the invention
The objective of the invention is to: overcome the above-mentioned defective of the above-mentioned existence of traditional braking device, provide a kind of new-type Security higher, the parking of reliable operation and the combined type break that travels.
Technological scheme of the present invention is as follows: be made of a plurality of movable friction plates, a plurality of static friction sheet, a plurality of spring, brake cylinder head, brake piston, braking housing and brake cylinder head; Movable friction plate, the alternate parallel arranged of static friction sheet, static braking housing endoporus is processed into the profile of tooth spline, and the outer fenestra of static friction sheet is processed into the profile of tooth spline, and the static friction sheet is loaded on the drag housing body internal tooth form spline and constitutes one; Movable friction plate profile of tooth spline endoporus is connected with external splines on the half shaft and becomes one, and the club head of master cylinder piston leans brake strip, and some springs are housed in the master cylinder rodless cavity, and spring action is in brake piston.
Movable friction plate of the present invention and static friction sheet are disc.
Movable friction plate periphery of the present invention is less than the outside diameter circle of braking housing internal tooth form spline.
Spring of the present invention is a butterfly spring.
The present invention has the following advantages:
1. this break braking working surface is totally-enclosed in the braking housing, can adapt to rugged environment such as road surface mud, water, sandstone, dust well, prevent that these pollutants from entering break service braking surface, it is than drum brake and disk type braker safety and reliability commonly used.
2. this wet multi-disk brake can increase and decrease the work logarithm of dynamic and static braking plate as required, adapts to the braking moment usage requirement of car load, helps the seriation of product.
3. this break also can be loaded between ransaxle main transmission and the planet wheel side reducer, and less braking moment of break after the transmission no-load voltage ratio, can produce a bigger braking moment on driving wheel, obtain satisfied braking effect..
4。This break adopts master cylinder to take back oil, oil cylinder loses pressure and is braked by butterfly spring, the controlling schemes that entrance pressure power oil brake unclamps, can prevent effectively that existing vehicle brake conduit from breaking or brake circuit leaks and cause braking oil pressure to descend, the malfunctioning accidents caused phenomenon of car brakeing, its safety reliability is higher.
5. after using this braking, traditional shutdown system will be cancelled, and two system combinations are one, and structure is simpler; Vehicle parking promptly can need not to operate parking brake system automatically with car brakeing, in the time of preventing from well to have vehicle parking now, forgetting handle brake slide car, and accidents caused phenomenon; Be that four-wheel is all braked when this break vehicle parking is housed, effect is hand braking better than existing.
6. long service life, maintenance load is very little, and break working surface gap need not to adjust.
Description of drawings
Accompanying drawing is a structural representation of the present invention.
Embodiment
The present invention is described in detail below in conjunction with accompanying drawing.
The present invention is made of a plurality of movable friction plates 1, a plurality of static friction sheet 3, a plurality of butterfly spring 7, brake piston 5, braking lid 2, braking housing 4 and brake cylinder head 6.Disc movable friction plate 1, static friction sheet 3 alternate parallel arranged, and envelope will be in the space that braking lid 2,4 combinations of braking housing form.Static braking housing 4 endoporus are processed into the profile of tooth spline, and the outer fenestra of static friction sheet 3 is processed into the profile of tooth spline, and static friction sheet 3 is loaded on the braking housing 4 internal tooth form splines, makes them constitute one; Movable friction plate 1 periphery is less than the outside diameter circle of braking housing internal tooth form spline, and movable friction plate 1 profile of tooth spline endoporus is connected with external splines on the half shaft and becomes one, and half shaft rotates the moving sheet that rubs that drives on it and rotates together.The club head of master cylinder piston 5 leans brake strip, and some butterfly springs 7 are housed in the master cylinder rodless cavity, and butterfly spring 7 acts on brake piston.
Have an amount of fluid in the break and be lubricated and cool off, the heat when being used for taking away braking improves dynamic and static friction plate operating conditions and improves its reliability; As the oil cylinder of break drive part with piston be distributed in brake shaft to, its quantity is some, decides on the needs of break.This break can be installed on by the ransaxle differential casing, also can be installed on appropriate locations such as ransaxle wheel reductor inboard.
