  • Patent number: 8960464
    Abstract: A coupler for transit cars includes a coupler anchor, a coupler mechanism supported to the coupler anchor by a deformation tube and draft gear element, and a coupler support mechanism. The coupler support mechanism includes two support arms pivotally mounted to a lower part of a coupling connector. A tension rod is provided for each support arm to control the pivotal displacement of each support arm. Each support arm further includes a torsion spring which is loaded as the support arm is pivotally displaced in an upward direction and unloaded as the support arm is pivotally displaced in a downward direction. The position of each support arm may be adjusted independently, thereby allowing adjustment of the coupler along longitudinal and lateral planes of the transit car.

  • Patent number: 7552830
    Abstract: A central buffer coupling for rail-mounted vehicles has a coupling shaft (1) and a drawgear (2) comprising a bearing bracket (4), whereby the rear end (3) of the coupling shaft (1) is connected to the drawgear (2) and coupled to the car body of the rail vehicle via the bearing bracket (4) of the drawgear (2) so as to be horizontally pivotable. The drawgear (2) includes a shock absorber (5, 8), wherein the shock absorber (5, 8) is configured such that upon the exceeding of a definable critical impact force being transmitted through the coupling shaft (1) to the drawgear (2), the connection between the drawgear (2) and the coupling shaft (1) is disengaged and the coupling shaft (1) is at least partially removed from the power flow transmitted to the drawgear (2).

  • Patent number: 6796448
    Abstract: A railcar draft gear housing formed from an austempered ductile iron casting having an original shape and including an open end, a closed end, and wall structure axially extending between the housing's ends. The wall structure of the housing defines an axial section between and spaced from the ends. The axial section of the wall structure is configured to withstand impact energy imparted to the housing in excess of 81,000 inch pounds while retaining and exhibiting substantially linear elasticity wherein the resultant ratio of stress to energy input remains substantially constant thereby allowing for flexible distortion of the housing in a manner promoting enhanced energy damping characteristics while allowing the casting to return to the original shape after the impact energy is released threrefrom.

  • Patent number: 6276542
    Abstract: A unique transit system incorporates at least one internally powered, wheeled, transport vehicle having both manual controls enabling a user to drive the vehicle on a surface street and an on-board computer (OBC) system enabling software control of at least vehicle steering and velocity. A controlled roadway system having a roadway surface upon which the transport vehicle runs on its internal power on the same wheels as on surface streets is provided as well. On surface streets off the controlled roadway the manual controls are active, and on the controlled roadway the software controls are active. Manual or computer control depends on whether the vehicle is on the controlled roadway or surface streets. The OBC communicates with a Master computer for the controlled roadway, providing a range of functions. The transport vehicles operate at a fixed and constant speed on the controlled roadway system.

  • Patent number: 4775059
    Abstract: To avoid, after excessive shocks in the underframe in the forestructure and at the coupling of a traction/thrust pivoted joint or device of a vehicle, deformations of a central buffer coupling at the underframe of the vehicle is proposed. Arranged between the carrier plate for the support of the traction/thrust device and the coupling uptake at the underframe in each instance is a shock absorber which in case of excessive shocks becomes deformed elastically and/or plastically and permits a deformation path preset for the force acting at the time.

  • Patent number: 4576294
    Abstract: In a rail vehicle with anticlimb equipment, the occurring normal shocks are absorbed by draw and buffer devices which are provided in tandem with the central buffer couplers. To take up excessive impacts, an excess-impact safety effective through deformation is built into the coupler bar of the central buffer coupler. The purpose of the inventive arrangement with an additional excess-impact safety is to be able, upon a collision accident, to take up further excess impacts, in addition to those which are absorbed by the excess-impact safety of the coupler bar. The additional excessive-impact safety is so disposed that it remains unaffected during the response of the excess-impact safety of the coupler bar.

  • Patent number: 4287834
    Abstract: The stops of a draft gear housing of a rail car central coupler have to meet relatively large tractive and compressive forces in service. Up to now the expense involved in the fastening of such stops has been very great. In many cases, where the stops or bearings were joined to the center or stub sill, cracks formed and/or the sill became deformed. This incurs considerable expense for repairs and means a loss of service while the vehicle is being repaired. In accordance with the instant disclosure, to avoid such problems the center or stub sill of the rail car is now made such that the front stop and the rear stop are integral parts of the sill.
