211~0300 PARTIALLY LINED DISK BRAKE FOR
INSTALLATION IN DRIVE MECHANISMS IN
INDUSTRlAL FACILITIES, CABLE RAILWAY
DRIVE UNITS, AND THE LIKE
In industry, for e~ample in conveyor systems of various kinds, such as conveyor belts and cranes, as well as in cable railways and ski lifts, partial-lining disk brakes are utilized with a brake disk arranged on a drive shaft or a driven shaft, at least one brake force generator for 5 closing a brake caliper by way of a lever system during the b~aking step, the t~vo brake levers of which act, with brake linings mourlted to e~rlt~ngeable supports, on the peApheral zone of the two brake disk snrf~es, as well as with a lifting device assoGiated with the brake force generator for opening the brake caliper by means of the lever system 10 during release of the brake.
Such a partially lined disk brake has been known, for e~ample, from the prospectlls "Scheibenbremse SB 14" [l:)isk Brake SB
14] by the company Bubenzer Bremsen Gerhard Bubenzer Ing. GmbH.
Disk brakes exhibît considerable advantages over the dNm 15 brakes which latter are predominantly utilized, in particular, in United States industry.
21003~0 Byvirtue of the use of highly developed friction pad materials in conjunction with the lining configuration and the ensuing favorable wear characteristic, disk brakes are distinguished by significantly longer operating lifetimes as compared with drum brakes. Another advantage 5 of disk brakes resides in that the braking torque can be varied by way of the disk diameter without altering the braking mechanics whereas in case of drum brakes a brake drum having the corresponding diameter must be chosen for changing the braking torque, necessitating at the same time braking mechanics adapted to the drum diameter.
Based on the irrefutable advantages of the disk brake, the drum brakes in industrial facilities of all kinds are increasingly replaced by disk brakes. This tendency also prevails in the industry of the United States.
One problem in replacing a drum brake by a disk brake in 15 existing facilities resides in that, on account of the limited mounting space between the drive motor and the gear system, the total dimension of the disk brake in the direction of the axis of rotation of the brake disk must not be substantially larger than the width of the brake drum of the drum brake. As far as the United States market is concerned, there is the 20 additional difficulty that the use of a space-consurning electromagnetic lifting unit with direct current operation is required for reasons of connecting the lifting unit into the circuit of the drive motor.
The invention is based on the object of developing a partially lined disk brake of the type di~cll~sed hereinabove with a compact, simple 25 structure and a high braking power.
This object has been attained according to the invention by a partially lined disk brake having the features of claim 1.
Suitable further developments of the invention are covered, in particular, by claims 3 and 4 as well as by the further dependent claims.
The partially lined disk brake according to this invention is S distinguished especially in the preferred embodiment with two brake calipers, due to the use of a lifting device for both brake calipers offset toward the outside in the brake disk plane, by a compact structure and a simple drive mech~ni~m for closing and opening the brake calipers. In existing industrial plants and the like operating with brake drums, the latter can be exchanged without difficulties ~g~in~t the novel partial-pad disk brake.
The invention is described in greater detail below with reference to two embodiments of a partially lined disk brake illustrated in the drawings wherein:
Figure 1 is a frontal view of a first embodiment of the novel partially lined disk brake, Figure 2 is a section along line II-II of Figure 1, Figure 3 is a frontal view of a second embodiment of the disk brake, and Figure 4 is a schematicview of the servo drive mech~ni~m for a disk brake with one brake caliper.
The partially lined disk brake 1, mounted on a base plate 2, according to Figures 1 and 2 for installation in conveyor belts, machine tools, crane facilities, cable railways, etc. exhibits as tbe main structural parts a brake disk 3 arranged on a drive shaft or driven shaft, a brake spring 4 for dosing a brake caliper 5 by way of a lever system during the braking step, the two brake lever pairs 6, 6, 7, 7 of which act, with brake linings 9 attached to çx~h~ngeable supports 8, on the peripheral zone of --0~00 the two brake disk surfaces 3a, 3b, as well as an electromagnetic lifting device 10 associated with the brake spring 4 and operated with direct current.
The brake lever pairs 6, 6; 7, 7 of the brake caliper 5 are ;
5 articulated to the base plate 2 and can be pivoted in a limited way in an outwardly displaced central plane 12-12 in parallel to the perpendicular plane 11-11 of the axis of rotation of the brake disk 3. -The free ends of the two brake levers 6 of one brake lever pair 6, 6 are joined together by a pivot pin 14 arranged in parallel to the brake disk plane 13-13, an operat;ng lever 15 being fixedly mounted to this pivot pin and projecting in the upward and downward directions past the pivot pin 14. The operating lever 15 is designed as a dual lever with two parallel, congruent individual levers 15a, 15b, the latter being connected to each other by the pivot pin 14 and two further pins 16, 17.
15 One end of the operating lever 15 is connected via the extended pins 16, 17 with another operating lever 18 arranged horizontally in an outwardly offset plane in parallel to the central pivoting plane 12-12 of the two brake lever pairs 6, 6; 7, 7. The operating lever 18 is likewise fashioned as a dual lever with two parallel, congruent individual levers 18a, 18b 20 which latter are joined by the pins 16, 17.
The two operating levers 15, 18 constitute a bent angle lever 20. ~
The brake spring 4, accommodated in a housing 21 attached ~ ~ -to the base plate 2, acts on a tie rod 22 articulated to a hinge pin 31 at - - :25 the free end of the outwardly bent operating lever 18 of the angle lever 20.
The electromagnetic lifting unit 10 is mounted on the base plate 2 to be offset toward the outside with respect to the axis of rotation o 23-23 of the brake disk 3 and comprises two lifting rods 24 forming a fork 25 and being horizontally adjustable in the brake disk plane 13-13 by an electromagnetic drive mechanism. The lifting rods 24 of the lifting device 10 are connected in articulated fashion by a hinge pin 26 to the one ends of the two single levers 27a, 27b of an angle lever 27 designed as a dual lever, the latter being pivotable about an a~is 28-28 parallel to the central pivoting plane 12-12 of the brake lever pairs 6, 6; 7, 7. The angle lever 27 is articulated with its other end to the lower end of a push rod 29 which latter is articulated with its upper end to a hinge pin 30 of the bent lever 18 of the angle lever 20 for operating the brake caliper 5 and is movable in the pivoting plane 19-19 of the lever 18 in the vertical direction.
A tie rod 32 with an integrated, automatic brake lining wear adaptor is articulated to the lower end of the lever 15 directly engaging the one brake lever pair 6, 6 of the brake caliper 5 and to the free ends of the other brake lever pair 7, 7.
In the second embodiment of a partially lined disk brake 33 utilized with preference, illustrated in Figure 3, this brake is equipped with two identical brake calipers 5 acting in diametrical opposition on the brake disk 3 and with a lifting unit 10 for opening both brake calipers 5.
In this brake disk arrangement, for releasing the two brake calipers 5, a rotatable shaft segment 34 is inserted, in place of a pivot pin 14, in the free ends of the one brake lever pair 6, 6 of the two brake calipers 5, and the two shaft segments 34 bridging the brake disk 3 are connected to each other by a flexible coupling 35 compen~tin~ for a displacement of the shaft segments 34 due to differing wear of the linings of the two brake calipers 5.
003~0 The kinematics of the servo drive mech~ni~m of the partially lined disk brakes 1, 33 during the braking step and during release of the brakes are clarified in Figure 2 by the guide arrows associated with the individual operating elements, the solid arrows indicating the braking step S and the dashed-line arrows indicating the release of the brakes.
Figure 4 shows a schematic view of the servo drive mechanism for a disk brake with one brake caliper, demonstrating the mode of operation of the lever system of the servo drive mech~ni~m in two parallel planes and in a plane perpendicular thereto.
