摘要： The body of a rail vehicle is lowered when it is stationary to facilitate ingress and egress. The body is raised in preparation for motion to provide satisfactory road clearance. In one embodiment of the invention, a lifting cylinder, in series with a supplementary spring, is extended during travel, and is contracted when the rail vehicle is stopped. In other embodiments, a hydraulic cylinder, either alongside, or coaxial with the supplementary spring, compresses the supplementary spring when the rail vehicle is stopped. In a further embodiment, the hydraulic cylinder is replaced with an electromechanical adjusting element such as a screw drive. A control system, preferably actuated by unlocking and locking of the door opening lock, actuates the lowering and raising of the body.

摘要： A wheel set guidance for trucks of rail vehicles, especially commuter traffic vehicles. To have a continuously extending floor on as low a level as possible, a truck with free wheels is proposed where the free wheels are mounted in pedestal bearings that are connected with a frame structure that is connected to the truck frame in such a way as to be pivotable in a vertical direction. One of the wheel sets can be driven, with the free wheels thereof being connected in a twist-resistant manner via gear arrangement, so that from a motion standpoint the same effect is achieved as if the driven wheel set were connected with a rigid wheel set shaft, but without this shaft being in the way of the floor, so that a vehicle equipped with this truck can have a continuously extending floor on a low level.

摘要： A bogie for rail vehicles, particularly commuter or short-haul vehicles, has two wheel sets spaced apart in the direction of travel. One wheel set is mounted upon a wheel mounting frame which is coupled to a tranverse member of the bogie frame by way of an intermediate beam member. The arrangement is such that a lateral force applied to one wheel of the set by a curved rail will be translated into a rotational force to rotate the wheel mounting frame and therewith the wheel set, to negate the aforesaid lateral force. Such an arrangement reduces wheel flange wear and the risk of derailment.

摘要： A multi-unit rail vehicle for commuter traffic. To keep the entry and exit of the vehicle only slightly higher than the level of the street, and to make it possible to travel through the entire vehicle without steps, a continuous, level central walkway is provided that is at the same height as the entryway. To accommodate the driving bogie, the wheel sets are driven via drive shafts and reduction gear mechanisms. The drive motors can be disposed to the side below the car body and beyond the pivot range of the bogie. If room permits, vertical motors can also be provided in one corner of the car body, with such a vertical motor also driving the wheel sets via drive shafts and reduction gear mechanisms. Advantageously, two drive motors can be provided that are disposed diagonally across from one another relative to the point of rotation of the bogie, with the drive shafts of the motors being parallel to the wheel sets, and torque being transferred via further drive shafts. To accommodate the central walkway, the cross members of the bogie are angled-off. By disposing the entryway and the continuous central walkway on the same level, loading and unloading of passengers is accelerated, stopping times are reduced, and expensive platforms at the level of the vehicle floors are eliminated.
