Problems solved by technology

In the working state of the chain guide, since the two installation parts are located at both ends, the force in the middle of the support will be relatively concentrated, which will cause the support to deform in the middle and affect the performance of the entire chain guide

Embodiment Construction

[0022] The invention relates to a chain drive system of an internal combustion engine, in particular to a guide rail support and a guide rail in the chain drive system.

[0023] figure 1 and figure 2 It is a three-dimensional schematic view of the guide rail support of the present invention, and the guide rail support 100 is formed by punching and bending a metal plate. In order for the guide rail on the fixed side to resist the tension or vibration of the chain and to guide it stably, a metal material having high strength, rigidity, and durability is required.

[0024] The guide rail support 100 has a plate-shaped body portion 1, which is arched and forms a mounting surface 10 facing the chain on the outside of the arch, on which a slide for guiding the chain can be installed ( not shown), the sliding member is made of a low-friction resin material. The first side in the width direction of the main body part extends vertically relative to the chain movement direction to f...

Abstract

The invention relates to a guide rail support piece and a guide rail. The guide rail support piece comprises a plate-shaped body part, at least one first mounting part vertically extending from the first side in the width direction of the body part and relative to the movement direction of a chain and at least one second mounting part vertically extending from the second side in the width direction of the body part and back to the movement direction of the chain. At least one third mounting part vertically extending from the first side in the width direction of the body part and back to the movement direction of the chain is arranged on the body part. The third mounting parts and the first mounting parts are located in different positions in the movement direction of the chain. The guide rail support piece is simple in structure and low in manufacturing cost, and in addition, the strength of the guide rail support piece is improved.

Description

technical field [0001] The invention relates to a chain drive system of an internal combustion engine, in particular to a guide rail support and a guide rail in the chain drive system. Background technique [0002] In order to stabilize and properly maintain the tension on the moving chain between the sprockets, guide rails are usually used which slide and guide the moving chain. [0003] Chinese patent CN104033553A discloses a chain guide rail, which includes a guide block for slidingly guiding the moving chain; and a base member for supporting the guide block along the chain movement direction. The base member is composed of a guide block supporting part extending in the chain movement direction, two parallel base body installation parts extending perpendicularly from both sides of the width direction relative to the chain movement direction, and two parallel base bodies arranged on both sides of the width direction The side wall portion is formed by punching a rolled ste...
