Problems solved by technology

[0004] A disadvantage of the known guide carriages is that a section of this lubricant flow path has to pass by the fastening holes at very short intervals
This creates problems in sealing the lubricant flow path against the outflow of lubricant

Embodiment Construction

[0027] figure 1 An exploded view of the guided vehicle 20 according to the invention is shown. The guided vehicle 20 includes a main body 30 made of non-hardened steel, which extends along the longitudinal direction 11 in a substantially constant, U-shaped cross-sectional shape. A V-shaped groove 33 is respectively arranged on the inner surface of the U-shaped leg 35, and a separate rolling surface liner 40 made of hardened rolling bearing steel abuts against the groove 33, respectively. The two rolling surface linings 40 extend along the longitudinal direction 11 with a substantially constant cross-sectional shape, wherein the rolling surface linings respectively have two vehicle rolling surfaces 41, so the guided vehicle has a total of four rows Rolling element (in figure 2 Reference numeral 21). The present invention can also be applied to some guided vehicles, for which the hardened rolling surface of the vehicle is directly arranged on the main body 30.

Abstract

A guide carriage for an elongated guide rail includes a main body, an end cap, and at least one row of rolling bodies accommodated in a continuous bypass channel. The end cap bears indirectly against a longitudinal end face of the main body and has a fastening bore through which a fastening screw passes. The fastening screw is screwed into the main body. The continuous bypass channel has a supporting portion and a return channel that are connected via a curved bypass channel that is arranged in the end cap. A lubricant flow path is arranged in the end cap and extends from a lubrication port to the row of rolling bodies. A first cavity is arranged between the fastening bore and the fastening screw. The first cavity forms a component of the lubricant flow path.

Description

Technical field [0001] The invention relates to a guided vehicle according to the preamble of independent claim 1. Background technique [0002] Document EP971140B1 discloses a guided vehicle which is arranged for use with elongated guide rails. The guided vehicle includes four rows of ball-shaped rolling elements, and the rolling elements are respectively accommodated in the associated continuous revolving channel. Each revolving passage includes a supporting section and a return passage, and the supporting section and the return passage are respectively connected to each other by a curved turning passage at their ends. The supporting section is defined by a vehicle rolling surface on the guided vehicle and a rail rolling surface on the guide rail, and the vehicle rolling surface and the rail rolling surface respectively extend in the longitudinal direction. All the steering channels are arranged inside two separate end caps, which are fixed on the two opposite longitudinal en...
