Definitions
- the invention relates to a block brake unit for rail vehicles, with a push rod designed as a threaded spindle of a play adjusting device, the end of which forms a rod head, via a connecting device having spherical surfaces, is coupled in a pressure-transmitting manner to a brake block holder movable in a transverse plane to the push rod, with the push rod being non-rotatable about its longitudinal direction
- Connecting device has a cross bolt, the two projecting ends of which engage in horizontal grooves.
- Such a block brake unit is known from EP-B-0010816.
- the known connecting device on the rod head of the push rod has a blind hole with a hemispherical bore base into which the corresponding spherical, rear Engages end of a rod-shaped transmission part.
- the transmission part is provided with a printing tar, which has a spherical surface on the front, the radius of which is substantially larger than that of the spherical surface at the rear end; both spherical surfaces have a common spherical center.
- the pressure plate lies with its spherical surface on a flat surface of the brake pad holder, to exclude lateral displacements, the brake pad holder is provided on both sides of the printer with a backward projecting vertical web, and nothing can be found in the document about devices for preventing vertical displacements of the printer relative to the brake pad holder.
- the transmission part can be penetrated near its rear end by a cross bolt, the projecting ends of which are guided in horizontal grooves on the rod head; furthermore, for this purpose the pressure plate can have lateral flats which are guided on the webs of the brake block holder and thus non-rotatably couple the transmission part to the brake block holder which is also rotatably guided by the pendulum guide.
- the push rod as a rod head has a spherical head which is mounted in a corresponding spherical bearing recess of the brake pad holder, and in that the spherical head is penetrated in the center by the transverse bolt which extends transversely to the push rod and has projecting ends engage in the horizontal grooves on the side of the bearing recess in the brake block holder.
- Fig. the front end of a block brake unit with rod head and brake block holder
- Connection device in view according to Fig.l, but also on an enlarged scale.
- the block brake unit according to Fig.l has a brake motor with transmission gear, which are arranged in a housing 1 shown only partially and which can be formed, for example, according to one of the prior art mentioned above or in another known manner.
- a push rod 2 in the form of a threaded spindle protrudes forward from the game next, which is also accommodated in the housing 1, and carries a ball head 3 at its front end as a rod head.
- the ball head 3 is in a correspondingly spherical bearing recess 4 of a brake block holder 6 provided with brake blocks 5 stored.
- the bearing recess 4 is designed in the manner of a blind bore 7 with a hemispherical bottom of the bore in the brake pad holder 6.
- the blind bore 7 is partially covered by a bearing ring 8, which, in a manner not shown, for example by a screw connection, fixed but releasably attached to the brake pad holder 6.
- the bearing ring 8 is, based on the blind bore 7, provided on the inside with a spherical zone-shaped inner surface 9, this inner surface 9 and the hemispherical bore bottom of the blind bore 7 have one common center point 10;
- the center of the ball of the ball head 3 is also located in the center of the ball 10.
- a sealing ring 11 is inserted into the inner surface 9 of the bearing ring 8, which cooperates with the ball head 3 and prevents dirt from penetrating into the blind bore 7.
- the ball head 3 is penetrated in the center by a horizontal cross bolt 12 which extends transversely to the push rod 2 and protrudes with its two ends 13 from the ball head 3 and engages in horizontal grooves 14 of the brake block holder 6 adjoining the blind bore 7 laterally; the housing-side ends of the horizontal grooves 14 are overlapped by the bearing ring 18 and covered so as to prevent contamination.
- the cross pin 12 is rotatably supported about its axis in the ball head 3.
- the ends 13 are flattened parallel to the horizontal grooves 14 to ensure a flat contact, in the exemplary embodiment the ends 13 are designed as a square.
- the push rod 2 carrying the ball head 3 engages with a shaft part 15 with radial clearance 16 through the bearing ring 8, which in this area has an opening section 17 which widens conically towards the housing 1 in this connection to the inner surface 9.
- the shaft part 15 is tapered towards the ball head 3, it is essential that it has a smaller diameter than the push rod 2 in the region of the passage through the bearing ring 8.
- the brake block holder 6 is suspended and guided in the usual way by means of a pendulum lever 18 on the housing 1, during braking and releasing processes, the brake block holder 6 thus experiences a circular path lying in a vertical plane around the upper articulation point of the pendulum lift 18 forward and backward movements.
- the brake pad holder 6 can experience horizontal displacements at right angles to the plane of the drawing in FIG. 1, the pendulum lever 18 can be correspondingly displaceably mounted or designed to be elastically deflectable.
- Rotary couplings 19 of this type are known in various designs; according to FIG. 3, as housing 20, they have an outer ring body designed as a hexagon, within which end faces 21 formed with radial splines or saw teeth a part 22 and the shaft part 15 firmly connected to the push rod 2 abut each other.
- the housing 20 is secured by means of a locking ring 23 against axial displacements relative to the push rod 2 in the direction of the brake block holder 6, between an inner shoulder 24 of the housing 20 and an inner shoulder 25 of the shaft part 15, a compression spring 26 is clamped, which loads the end faces 21 in the mutual pressing direction.
- the housing 20 is connected to the part 22 and thus the push rod 2 in a rotationally fixed manner by means of a screw connection or axial toothing 27.
- a pin extension 28 of the push rod 2 is rotatably mounted in a corresponding axial blind bore 29 of the shaft part 15.
- the push rod (2) which is designed as a threaded spindle of a device closest to the game, is mounted in a corresponding bearing recess (4) of the brake block holder (6) by means of a ball head (3).
- This enables the push rod (2) to be deflected relative to the brake block holder (6) without constraint on all sides with constant pressure force transmission, so that the push rod linkage on the brake block holder (6) means that no bending or transverse forces can be introduced into the push rod (2).
- the ball head (3) is penetrated by a transverse bolt (12), the projecting ends of which are guided in horizontal grooves (14) of the brake pad holder (6) in order to hold the push rod (2) about its longitudinal direction.
- a rotary coupling that transmits pressure force and only disengages when a certain limit torque is exceeded can be arranged, whereby a manual resetting of the lash adjuster is made possible by turning the push rod.
