Embodiment Construction

[0018] figure 1 The tensioning device 1 shown in the figure 1 On the housing not shown in the figure (especially the crankcase of the internal combustion engine). The base part 2 having an almost cup-shaped configuration forms centrally an axially protruding bearing pin 3 which contains a centrally located receptacle 5 designed as a stepped bore 4 . The free end of the bearing pin 3 is used to accommodate a sliding bearing 6 which, in order to form a rotational bearing 7 , is surrounded by a hub 8 which is integrally connected to a pivoting arm 9 . The free end of the eccentrically arranged pivot arm 9 is intended to be accommodated in figure 1 Tensioner pulley not shown. In order to effectively lock or fix the rotating arm 9 on the support bolt 3 of the base member 2, a snap connector 10 is provided, which is composed of a hole plate 11, and an axially protruding protrusion 12 It is connected to the perforated disk 11 on one side. In the mounted state, the bore plate 11 ...

Abstract

The invention relates to a tensioning device (1) of a traction mechanism drive, comprising a base part (2) and a pivot arm (9), between which base part (2) and pivot arm (9) is inserted a torsional spring (17) which exerts both a torque on the pivot arm (9) and also a spreading force between the base part (2) and the pivot arm (9). To axially secure the pivot arm (9) to the base part (2), a latching connector (10) is provided which has a perforated disc (11) which is supported on a bearing pin (3) of the base part (2) and which extends radially into a region of the hub (8) of the pivot arm (9). An axially projecting extension (12) of the latching connector (10) engages into a receptacle (5), which is designed as a stepped bore (4), of the bearing pin (3), wherein an end region (14) is supported, in a radially flared fashion, on a step (15) of the receptacle (5).

Description

technical field [0001] The invention relates to a tensioning device for a traction mechanism drive, basically comprising a base part and a pivoting arm, between which a torsion spring is inserted, which causes a tension in the pivoting arm A moment oriented in the tight direction and causes a spreading force between the pivot arm and the base member. Furthermore, the tensioning device comprises a damping device comprising a friction element interposed between the torsionally rigid and pivotable components of the tensioning device. The swivel bearing integrated in the tensioning device consists of a torsionally rigid pin connected to the base part, on which the swivel arm is rotatably mounted via a hub, wherein the components are joined together in a secure manner by means of a positioning element together. The tensioning pulley, which is rotatably positioned on the free end of the swivel arm, is supported on the traction mechanism of the traction mechanism drive in the mount...
