专利汇可以提供Brake system for a travelling brake carriage of an aerial cableway专利检索，专利查询，专利分析的服务。并且A brake system for a travelling brake carriage of an aerial cableway, the travelling brake carriage embodying a brake carriage body and a housing provided with a braking spring accumulator. A piston and cylinder arrangement is operatively associated with the braking spring accumulator. The cylinder has a compartment for a braking fluid medium, and the braking spring accumulator applies a braking force to such fluid medium via the piston and cylinder arrangement. At least one braking block is supported by the brake carriage body, said braking block being provided with cooperating pairs of braking shoes, one shoe of each pair being arranged to each side of the associated supporting cable. A respective sliding piston acts upon each braking shoe. Means are provided for transmitting the pressure of the fluid medium within the piston and cylinder arrangement against the braking shoes in a direction urging the latter into a braking position towards the associated support cable, and means are provided for applying a counterforce against the braking shoes in a direction opposite to the braking urging action exerted by the fluid medium of the piston and cylinder arrangement.，下面是Brake system for a travelling brake carriage of an aerial cableway专利的具体信息内容。

权利要求

1. A brake system for a travelling brake carriage operatively connected with a travelling support carriage of an aerial cableway equipped with at least one support cable for supporing said travelling support carriage and said travelling brake carriage, the improvement comprising said travelling brake carriage embodying a brake carriage body, a housing extending in the lengthwise direction of the travelling brake carriage, said housing being provided with a braking spring accumulator, a piston and cylinder arrangement operatively associated with said braking spring accumulator, said cylinder having a compartment containing a first braking fluid medium, said braking spring accumulator continually applying a braking force upon said first fluid medium via said piston and cylinder arrangement, at least one braking block supported by said brake carriage body, said braking block being provided with cooperating pairs of braking shoes, the shoes of each pair being arranged to respective opposite sides of the associated support cable, a respective double-acting piston member having first and second opposed faces acting upon each braking shoes, unobstructed means for transmitting the pressure of the first fluid medium within the piston and cylinder arrangement against said first face of each of said double-acting piston members and thereby against the braking shoes in a direction urging the latter into a braking position towards the associated support cable, and means for continually applying a counterforce against the braking shoes in a direction opposite to the urging force exerted by the first fluid medium of the piston and cylinder arrangement, said means for applying a counterforce including means for controllably feeding a second fluid medium at a pressure greater than the pressure of the first fluid medium against said second face of each of said double-acting piston members.

2. The brake system as defined in claim 1, wherein said braking spring accumulator contains spring means acting upon the piston of said piston and cylinder arrangement.

3. The brake system as defined in claim 1, wherein said braking block is provided with bores extending substantially radially with respect to said support cable, each of said double acting piston members being slidably arranged in one of said bores and cooperating with an associated braking shoe.

4. The braking system as defined in claim 3, wherein said means for applying a counterforce to the braking shoes incorporates conduit means for feeding pressurized oil to said second face of each sliding double acting piston member.

5. The braking system as defined in claim 1, wherein said housing is arranged at the region of the lengthwise axis of the travelling brake carriage and substantially symmetrically with respect thereto.

6. The brake system as defined in claim 1, wherein a pair of support cables is provided for supporting the travelling support carriage and the travelling brake carriage, said travelling brake carriage being provided with one such braking block for each such support cable, each braking block being equipped with said cooperating pairs of brake shoes, one of the brake shoes of a pair being arranged to one side and the other of the same pair to the opposite side of the associated support cable, each braking block being provided with a bore for each associated brake shoe, a respective sliding piston member defining said double-acting piston members arranged in each bore and cooperating with an associated brake shoe.

7. The brake system as defined in claim 6, wherein said means for controllably feeding a second fluid medium incorporates an oil conduit system for feeding oil under pressure to the double-acting piston members in the bores of the braking block for urging the associated braking shoes in a direction away from the associated support cable.

8. The braking system as defined in claim 7, wherein said transmitting means incorporates conduit means flow communicating with said first face of each of the double-acting piston members within the bores for urging such double-acting piston members in a direction towards the associated support cable.

9. A brake system for a travelling brake carriage of an aerial cableway equipped with at least one support cable for supporting said travelling brake carriage, the improvement comprising said travelling brake carriage embodying a brake carriage body, a housing extending in the lengthwise direction of the travelling brake carriage, said housing being provided with a brakIng spring accumulator, a piston and cylinder arrangement operatively associated with said braking spring accumulator, said cylinder having a compartment containing a first braking fluid medium, said braking spring accumulator continually applying a braking force upon said first fluid medium via said piston and cylinder arrangement, at least one braking block supported by said brake carriage body, said braking block being provided with cooperating pairs of braking mechanisms, the braking mechanisms of each pair being arranged to respective opposite sides of the associated support cable, means for transmitting the pressure of the first fluid medium within the piston and cylinder asrrangement against the braking mechanisms in a direction urging the latter into a braking position towards the associated support cable, and means for continually applying a counterforce against the braking mechanisms in a direction opposite to the urging force exerted by the first fluid medium of the piston and cylinder arrangement, said means for applying a counterforce including means for controllably feeding a second fluid medium at a pressure greater than the pressure of the first fluid medium against the braking mechanisms, said counterforce being sufficient to normally maintain said braking mechanisms in a non-braking position during proper functioning of said aerial cableway.
