With reference to accompanying drawing, in endless-track vehicle, left and right each complete disc brake is between engine compartment comprehensive actuator output shaft and side speed reducer input shaft.Under the effect of control system and actuator thereof, bear the work of normal brake application, emergency braking, parking braking, can provide one to make the moment of torsion that vehicle stops from top speed and vehicle is remained on 60% the slope.The load mode of complete disc brake is under the effect of control fluid, to compress dynamic and static dish through master cylinder, realizes the purpose of slowing down or stopping through rubbing.
The original installment state of complete disc brake is the Parking state of break, so vehicle should carry out freeing of parking function earlier before starting; In the going of vehicle (not using parking braking function to stop in going in principle); The driver will operate brake petal as required; Make the control fluid of corresponding brake circuit (normal brake application oil circuit or emergency braking oil circuit) inject master cylinder; Rotation → the promotion of master cylinder action → connection lever with rotate involute positioning block → rotations wheel ball bearing assembly rotations → promotions that wheel ball bearing is fitted together and move wheel ball bearing and move (elimination Separation) → compress brake disc (linking to each other with spline) → separate (make mobile wheel ball bearing return by 15 because of moving the spring that stretches, two extension springs make rotation wheel ball bearing return) with the brake drum of side speed reducer.
Assembling summary of the present invention: supporting roller (10) is housed on the raceway of land (11); Rotating wheel ball bearing assembly (5) is contained on the land (11) through the seam location; Raceway floats on supporting roller 10 below it; Moving wheel ball bearing (4) is contained on the rotation wheel ball bearing assembly (5) through the seam location; Between the bullet groove of rotation wheel ball bearing assembly 5 and the bullet groove of mobile wheel ball bearing 4 roller (9) is housed; Thermal baffle (8) is bonded on the end face of the pressing plate assembly (being called for short quiet dish II) (3) of being with the C/SiC friction facing with high-temperature plastic; And link to each other with the internal spline of mobile wheel ball bearing with involute outer spline, above-mentioned parts assemble the back between land (11) and quiet dish II (3) with 21 springs (6) that are used to make mobile wheel ball bearing return with its axial pulling, will be placed on the brake disk assembly (abbreviation Moving plate) (2) of C/SiC friction facing then on the end face of the quiet II of coiling (3) that has combined; After all parts assemble in order; To be contained on the inner stopper of land (11) through the outer stopper location with the tie-plate assembly (being called for short quiet dish I) (1) of C/SiC friction facing at last, and circumferentially fix, be contained on the side speed reducer housing and through quiet dish I (1) outer stopper location and fix through land (11) and side speed reducer with two bolts.
Its structural feature is following:
(1), adopt complete disc brake, the effective friction area of break is increased considerably, friction element thermal capacity increases, the average temperature rising of friction element significantly descends, thereby working life, braking moment and the reliability of break are increased substantially;
(2), complete disc brake travelling brake, emergency braking and parking braking adopt a cover actuator, control system is simple in structure;
(3), two quiet dishes (quiet dish I (1), quiet dish II (3)) are arranged, a Moving plate (2) in this break.On quiet dish I (1) and the quiet dish II (3) respectively riveted joint have eight C/SiC friction facings and riveted joint that flat key is arranged, Moving plate (2) is gone up riveted joint to be had 12 C/SiC friction facings and rivets flat key, its operating conditions: dry type are arranged.Because the C/SiC friction facing that adopts in the design; Have better thermostability, wear resistance; Especially dynamic and static friction factor is greatly improved, and so just makes the friction facing specific pressure descend 36% than copper-base powder metallurgy, and the physical dimension of parts is reduced; The specific pressure value reduces, and the reliability of system improves;
(4), land (11) is circumferentially fixed with the seam location and with two bolts with the tie-plate assembly (1) (quiet dish I) that has the C/SiC friction facing; Moving plate behind this unit construction (2) links to each other with the input end of side speed reducer through involute splines, and land (11) connects seam and the side speed reducer location and with ten five screws circumferentially fixing of back through quiet dish I (1) with quiet dish I (1); For guarantee heat radiation good with the friction facing wearing and tearing after chip removal, in Moving plate (2) and quiet structure of coiling I (1), designed radiating fin and groove.
(5), being processed with involute outer spline on the pressing plate assembly (3) of band C/SiC friction facing (quiet dish II) links to each other with internal spline on the mobile wheel ball bearing (4); It is structurally become one; When under the effect of control system and actuator thereof, promote with rotating the involute positioning block (14) that the wheel ball bearing assembly is fitted in, make and rotate the rotation of wheel ball bearing assembly; Thereby promote to move wheel ball bearing (4) and pressing plate (3) (quiet dish II) same moved further (elimination Separation), compress brake disc.The pressing plate assembly (3) of band C/SiC friction facing (quiet dish II) square key is inserted in the keyway of quiet dish I (1), guarantees quiet dish II (3) the moving of no clamping stagnation in the keyway of quiet dish I (1), and the while can prevent quiet dish II (3) rotation;
(6), on the raceway of land (11) supporting roller (10) is housed; Supporting roller (10) is positioned at land (11) and rotates between the wheel ball bearing assembly (5); Play the effect of rotating the wheel ball bearing assembly of supporting, the resistance of in rotating wheel ball bearing assembly (5) movement process, reducing friction goes slick it;
(7), to move wheel ball bearing (4) and the bullet groove of rotating wheel ball bearing assembly (5) be to be the bullet groove centre of sphere with its center, produces in the circular movement process through the skewed slot angle to move axially, frictional loss is little, can realize that bigger leading compare;
(8), rotate on the wheel ball bearing assembly and be inlaid with involute positioning block (14), thereby make on the master cylinder be close on the flank of tooth of involute positioning block (14) of break with the arc-shaped tooth of lever.The working stroke of master cylinder and the wearing and tearing stroke that the adjustment stroke satisfies friction facing have been guaranteed;
(9), move between wheel ball bearing (4) and the quiet dish II (3) thermal baffle arranged, separate since during braking a large amount of heat of rapid generation be delivered on the mobile wheel ball bearing (4);
(10), separate thoroughly.Be used to make the spring (6) that moves wheel ball bearing and rotate the wheel ball bearing return for guaranteeing thorough separation of brake disc (2) and quiet dish I (1) and quiet dish II (3), having designed in the structure;
(11), complete disc brake is easy to realize seriation, generalization; It is integrated to be easy to form braking technology; Can under the situation that does not change radial dimension, only change number of friction pairs and can adjust braking moment, to adapt to the requirement of vehicle different capacity, the speed of a motor vehicle, weight.
