Definitions
- the invention relates to a block brake for rail vehicles, in which a brake linkage acted upon by a brake cylinder acts radially on at least one wheel set of the chassis of the rail vehicle via brake blocks consisting of brake block shoes and brake block soles.
- Block brakes for rail vehicles are known from practice, particularly in the field of freight traffic, via which up to a max. permissible speed of 120 km / h the entire braking of the rail vehicle takes place.
- the brake blocks consisting of brake block shoes and brake block soles act directly on the tread of the wheel tire of the wheel set.
- the brake pads are suspended from a brake cross-member, which is usually designed in the form of a triangle (brake triangle).
- the brake block shoes with the brake cross member are articulated in the rail vehicle or in the chassis of the rail vehicle on its frame and are acted upon by a brake cylinder via a brake pull rod with the interposition of the center brake linkage and any connecting levers between the brake cross members.
- This block brake described above fulfills its task up to the stated speed at the loads customary in goods transport of up to 22.5 t per axle and consists of simple, economically manageable components which can be maintained with little effort.
- a disadvantage has been found, however, that the braking heat generated during braking leads to damage to the wheel tire and the tread. The consequence of this is a rough and wavy tread u. U. even cracks in the tread.
- the mechanical action of the brake pads on the tread also causes ripples to form on the tread. These changes in the tread of the wheel tire result in a very high rolling noise. If the wheel tire is damaged by crack formation, the wheel set must be replaced.
- the object of the present invention was to arrange and design the inherently economical block brake in a rail vehicle in such a way that higher braking powers can be achieved, that damage to the wheel tires of the wheel set is avoided, and that the __bollling noise of the wheel sets is minimized.
- this object is achieved in that at least one rotationally symmetrical brake body is fixedly arranged on the wheel set shaft of the wheel set between the wheel disks of the wheel set, on the outer surface of which the brake pad applied rests.
- At least one brake pad can be provided on both sides of the wheelset shaft and both brake pads, acting radially on the wheelset shaft, rest on the outer surface of the brake body when acted upon.
- the wheel axle is kept free of additional longitudinal forces, so that the wheel set can largely adjust itself to the course of the track even when braking.
- two or more brake bodies are arranged on the wheelset shaft and a brake pad acting on each of the brake bodies is provided on both sides of the wheelset shaft. Increasing the number of brake bodies on a wheelset shaft enables a higher braking power to be achieved.
- the brake block shoes are suspended from brake block hangers and are mounted on a brake crossmember.
- the brake crossmember is designed as a brake triangle.
- each brake pad can be guided axially on the brake body.
- the brake cross member is guided laterally on the frame of the chassis or the underframe of the rail vehicle.
- FIG. 1 shows the vertical longitudinal section through the part of a running gear of a rail vehicle with the block brake according to the invention
- FIG. 2 shows the top view of the part of the drive according to FIG. 1
- FIG. 3 shows the front view of the part of the drive according to FIG. 1
- the wheel set (1) consisting essentially of the wheel set shaft (2) with the wheel disks (3) is, as is known from practice, via external axle bearings (4) and leaf support springs, not shown, with the interposition of Schaken ⁇ hangers, also not shown suspended on spring brackets (5) of the base frame (6) of the rail freight wagon.
- a rotationally symmetrical brake body (7) is arranged on the wheelset shaft (2) on both sides of the central longitudinal axis of the rail freight wagon.
- the rotationally symmetrical brake body (7) has a cylindrical outer surface (8) and a flange (9) projecting beyond the outer surface (8).
- a brake cross member (11) is articulated on each side of the wheel set (1) via brake block hangers (10).
- the brake crossmember (11) carries a brake block (14) consisting of a brake block sole (12) and a brake block shoe (13) at each of its two longitudinal ends.
- the brake blocks (12) each Bremklotz- shoe (13) have the circumferential surface (8) of the P Bremskör- ers (7) •
- each brake cross member (11) is articulated to a brake lever (15), a brake lever (15) with its upwardly projecting end being articulated on a fixed point bearing (16) of the underframe (6) of the rail freight wagon.
- the second brake lever (15) carries at its upper free end (marked A) a brake pull rod, not shown.
- both brake levers (15) are articulated to one another by means of a brake lever connector (17).
- the brake lever (15) carrying the brake cable rod is further articulated via its articulation (18) carrying the brake lever connector (17) to a brake hanger (19), which is also articulated to the underframe (6) of the railway freight wagon.
- the wheel set (1) is braked by means of a brake cylinder by means of the brake cable rod (not shown) and a center brake linkage (also not known from practice) in that the brake blocks (14) via the brake block soles (12) against the lateral surface (8 ) of the brake body (7) are pressed.
- a wheel flange on each longitudinal side of the brake body (7) instead of the one wheel flange (9) of the brake body (7) or to cover the outer surface (8) of the brake body (7) with a brake block (14).
- lateral contour for example convex or concave. It is also conceivable to guide the brake crossmember (11) by lateral guides in the base of the rail freight wagon.
- the brake blocks (14) can be guided onto the brake body (7) on the one hand in such a way that the required transverse movements of the wheel set (1) take place relative to the brake crossmember (11) and thus to the brake block (14) and on the other hand in such a way that the transverse movements of the wheel set (1) are transmitted to the brake crossbars (11) and thus to the brake blocks (14) and that axle brake linkages consisting of brake blocks and brake crossbar swing with these transverse movements.
