Embodiment Construction

[0077] figure 1 An exploded view of a guided vehicle 20 according to the invention is shown. The guide carriage 20 comprises a main body 30 made of unhardened steel, which extends in the longitudinal direction 11 with a substantially constant, U-shaped cross-sectional shape. Arranged on the inside of the U-legs 35 are respectively V-shaped grooves 33 , against which a separate running track pad 40 of hardened rolling bearing steel rests in each case. Two running track pads 40 extend in the longitudinal direction 11 with a substantially constant cross-sectional shape, wherein the running track pads each have two vehicle running tracks 41a; 41b, so that the guide vehicle 20 has a total of four rows of rolling bodies ( figure 2 The reference number is 21).

[0078] An end cap 50 with an inner longitudinal end face 55 abuts directly on two opposite, planar longitudinal end faces 31 of the main body 30 . The two end caps 50 are designed identically, here being produced from pl...

Abstract

A guide carriage is configured for use with an guide rail. The guide carriage has at least one row of rolling bodies received in a circulatory channel. The circulatory channel has a load-bearing section and a return channel connected together at their ends by a deflection channel. The load-bearing section is delimited by a carriage raceway on the guide carriage and a rail raceway on the guide rail. At least one sealing lip is arranged in sealing engagement with the guide rail when the guide carriage is mounted on the guide rail. At least one separate rolling-body guide part, composed in one piece of an elastomer, has two deflection sections, between which at least one guide section, extending longitudinally, is arranged. An associated sealing lip is arranged on the guide section. At least one radially inner deflection surface of a deflection channel is arranged on each deflection section.

Description

technical field [0001] The invention relates to a guided vehicle according to the preamble of claim 1 . Background technique [0002] A guided vehicle is known from DE 10 2007 056 862 A1, which is provided for use with longitudinally extending guide rails. The guide carriage comprises four rows of spherical rolling bodies, which are each accommodated in an associated continuous running channel, wherein the invention can also be used for spherical rolling bodies. Each running channel comprises a load-bearing section and a return channel, which are each connected to each other at two opposite ends by a curved deflection channel. The carrier section is delimited at the guide vehicle by a vehicle running track and at the guide rail by a guide rail running track, which each extend in the longitudinal direction. All deflection channels are arranged inside two separate end caps, which are fastened to two opposite longitudinal end faces of the main body of the guide vehicle. [0...
