Abstract
The transverse coupling assembly for the end trucks utilizes a hollow shaft which is mounted via a bearing to a middle truck or vehicle body and connected via linkages to the two end trucks. In one embodiment, the shaft houses a torsion spring element which is pretensioned and which connects the shaft to a linkage. In another embodiment, the shaft can be provided with partitions to form a storage space for a fluid operating medium, diesel oil or the like.
Claims13
In combination with a rail vehicle having at least two longitudinally spaced trucks for supporting a body;
- a transverse coupling assembly for coupling said trucks comprising
- a hollow shaft disposed longitudinally of said trucks and said vehicle,
- bearing means supporting each end of said shaft relative to said body;
- a torsion spring element extending within said shaft at least over one end section, said spring element being secured at one end to said shaft and being relatively rotatable at an opposite end to said shaft within a predetermined angle;
- and
- a pair of linkages, each linkage connecting a respective one of said trucks to a respective end of said shaft and including a lever secured to said torsion spring element and connected to a respective one of said trucks.
A transverse coupling assembly for a rail vehicle having at least two longitudinally spaced trucks, said assembly comprising
- a hollow shaft,
- a means supporting each end of said shaft relative to a vehicle body,
- a torsion spring element extending within said shaft at least over one end section, said spring element being secured at one end to said shaft and being relatively rotatable at an opposite end to said shaft within a predetermined angle;
- and
- a pair of linkages, each linkage being connected to a respective end of said shaft for connecting said shaft end to a truck and including a lever secured to a respective end of said torsion spring element.
In combination with a rail vehicle having at least two longitudinally spaced trucks for supporting a body;
- a transverse coupling assembly for coupling said trucks comprising
- a hollow shaft disposed longitudinally of said trucks;
- a pair of spaced-apart partitions in said shaft defining a storage space therebetween for receiving and storing a fluid operating medium;
- means supporting each end of said shaft relative to said body, said means including a joint-like internal bearing within one end of said shaft and having an inner ring secured to a journal pin in a pillow block;
- and
- a pair of linkages fixedly connected to said shaft, each linkage connecting a respective one of said trucks to a respective end of said shaft.
A transverse coupling assembly for a rail vehicle having at least two longitudinally spaced trucks, said coupling assembly comprising
- a hollow shaft disposed longitudinally of said trucks;
- means for supporting each end of said shaft relative to a vehicle body, said means including a joint like bearing disposed within each end region of said shaft and a journal pin extending from said bearing;
- a pair of linkages fixedly connected to said shafts, each linkage connecting a respective one of said trucks to a respective end of said shaft;
- and
- a pair of spaced-apart partitions in said shaft defining a storage space therebetween for receiving and storing a fluid operating medium.
