Abstract

The utility model discloses a vehicle wet-type integrated brake which consists of a crank, a swing arm, a plurality of static friction plates, a plurality of dynamical friction plates, a braking shell and a braking cover body, wherein two ends of the crank are supported in the static braking shell, the outer part of the upper end of the crank is connected with a triangular spline inner hole at one end of the swing arm through a triangular spline, the other end of the swing arm is provided with a through hole articulated with a braking driving element, a braking shell inner hole is machined into a tooth-shaped spline, the disc-shaped static friction plates and dynamical friction plates with working braking friction are arranged at intervals, the static friction plates with excircles provided with the tooth-shaped splines are arranged on the static tooth-shaped splines in the braking shell to combine the static friction plates with the splines together. The vehicle wet-type integrated brake can well adapt to harsh operation conditions such as mud, water, gravel and dust on road surfaces, and prevent similar pollutants from entering working friction surfaces of the brake, with high safety and reliability. Moreover, a parking system can be removed and combined with the vehicle wet-type integrated brake together, thus having simple structure. The vehicle wet-type integrated brake has long service life and convenience in maintenance, and a brake clearance does not need to be adjusted.

Description

Automobile-used wet type synthetical restraint device

Technical field

The utility model relates to a kind of braking device, relates in particular to a kind of automobile-used wet type synthetical restraint device.

Background technique

At present the motor vehicle braking system of various vehicles such as mine, engineering machinery generally by parking brake system, (also the claiming work) braking system of travelling constitutes, the form of service brake mainly contains these breaks such as shoe brake, clipper disk brake because of being subjected to structure influence, its braking working surface exposes a bit, some can't seal, the abominable applying working condition influence of pollutants such as road surface mud, water, sandstone, dust, make its braking qualitative change poor, cause potential safety hazard.The power of these breaks is directly from oil pressure or air pressure in addition, and the deficiency of retardation pressure also can have a strong impact on braking effect.If brake oil, tracheal rupture are then braked total failure.

Summary of the invention

The purpose of this utility model is: overcomes the above-mentioned defective of prior art, a kind of good braking effect, safe and reliable, long service life is provided, and easy to maintenance, the automobile-used wet type synthetical restraint device that brake clearance need not to adjust.

The utility model is made up of crank throw, swing arm, a plurality of static friction sheet, a plurality of movable friction plate, braking housing, braking lid; The crank throw two supports is in static braking housing, the crank throw upper end is outside to be connected by the serration spline endoporus of serration spline with swing arm one end, the swing arm the other end is that through hole and braking driving element are hinged, braking housing endoporus is processed into the profile of tooth spline, disc service braking friction movable friction plate, static friction sheet are alternately, the static friction sheet that has the profile of tooth spline at cylindrical is loaded on the static braking housing internal tooth form spline, and both are become one.

Movable friction plate cylindrical described in the utility model is less than braking housing internal tooth form spline outside diameter circle.

The utlity model has following characteristics: 1, dynamic and static braking plate, totally-enclosed in the braking housing, can adapt to abominable applying working condition such as road surface mud, water, sandstone, dust well, prevent that this pollutant from entering break work friction surface, cause poor stop even inefficacy, than drum brake and clipper disk brake safety reliability height commonly used.2, and the work logarithm that can increase and decrease dynamic and static braking plate as required make the braking moment of break adapt to the usage requirement of car load, it helps the seriation of product.3, this break is loaded between ransaxle main transmission and the planet wheel side reducer, and less braking moment of break after the wheel reductor no-load voltage ratio, just can produce a bigger braking moment on driving wheel, obtain satisfied braking effect.4, can adopt spring reset single-acting hydraulic jack driving mode, when the hydraulic oil of oil hydraulic cylinder takes back oil, hydraulic cylinder piston rod is under action of reset spring, retraction drives break swinging arm usefulness in cylinder, this decompression braking, the controlling schemes that entrance pressure power oil brake unclamps is by oil, atmospheric pressure safety and reliability.And shutdown system can be cancelled, two systems unite two into one simple in structure.5, long service life, easy to maintenance, brake clearance need not to adjust.

Embodiment

Below in conjunction with accompanying drawing the utility model is elaborated.

The utility model is made up of crank throw 1, swing arm 2, a plurality of static friction sheet 3, a plurality of movable friction plate 4, braking housing 5, braking lid 6.Crank throw 1 two supports is in static braking housing 5, and outside, crank throw 1 upper end is connected by the serration spline endoporus of serration spline with swing arm 2 one ends, and swing arm 2 the other ends are that through hole and braking driving element are hinged.Braking housing 5 endoporus are processed into the profile of tooth spline, and the disc service braking rubs movable friction plate 3, static friction sheet 4 alternately, and the static friction sheet that has the profile of tooth spline at cylindrical is loaded on the static braking housing 5 internal tooth form splines, and they are become one.Movable friction plate 4 cylindricals are less than braking housing 5 internal tooth form spline outside diameter circles, external splines on movable friction plate 4 profile of tooth spline endoporus and the ransaxle on the semiaxis is connected and becomes one, ransaxle rotates the moving sheet that rubs of drive and moves with it, there is an amount of fluid in the break and is lubricated and cools off, the heat when taking away braking.

The utility model can be installed on by bolt by the ransaxle differential casing, also can be installed on ransaxle wheel reductor inboard.When this break was not braked, the break swing arm was in relaxation state, and crank throw does not act on brake strip, and had the gap between the brake strip, separated between dynamic and static friction, and half shaft can unrestricted motion, and the wheel on the ransaxle must give freely and travelling; When needing braking, dynamical element (available single-acting hydraulic jack) acts on swing arm, drive swing arm and rotate (direction as shown is a clockwise direction), swing arm drives door shape crank throw by serration spline and together rotates, crank throw promotes the left surface that (from direction as shown) presses the right of braking enclosure interior to the right with dynamic and static friction plate, dynamic and static friction plate working surface is tightly contacted, reach braking effect.The back dynamical element that finishes resets swing arm to loosen, and break is in non-braking state again.
