Problems solved by technology

[0003] When the current tensioner is assembled, the tensioning force of the tensioner is fixed. In this way, when the tensioner is assembled for different models, there are often different requirements for the tensioning force of the tensioner, which requires Different types of tensioners are manufactured for different models, and the manufacturing cost is relatively high

Embodiment Construction

[0028] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0029] Depend on Figure 1 to Figure 7 As shown, the dual-torque variable gear mechanical tensioner of the present invention includes a cylinder body 1 , a swing arm 2 , a first elastic element 3 and a second elastic element 4 .

[0030] The swing arm 2 is installed on the cylinder body 1, and the swing arm 2 and the cylinder body 1 are connected by a rotating shaft 202. The rotating shaft 202 has a central axis X, and the swing arm 2 can rotate around the central axis X relative to the cylinder body 1. Belt pulley 6 is rotatably installed on the swing arm 2. The effect of belt pulley 6 is to compress the belt to apply tension to the belt, so that the belt is tensioned, so as to facilitate the normal operation and transmission work of the belt.

[0031] The first elastic element 3 is located between the cylinder body 1 and the swing ...

Abstract

The invention discloses a dual-torque variable-gear mechanical tensioner comprising a cylinder, a rocker, a first elastic element and a second elastic element. The rocker is mounted on the cylinder and can rotate relative a central axis of the cylinder; the first elastic element is disposed between the cylinder and the rocker; the first elastic element is used for biasing the rocker, so that the rocker can rotate in a first direction relative to the cylinder; the second elastic element is mounted on the cylinder and is used for applying torque to the cylinder so that the rocker can rotate in the first direction relative to the cylinder; the cylinder is provided with a gear mechanism used for adjusting torque of the second elastic element. The dual-torque variable-gear mechanical tensioner allows tension to be adjusted through gear varying to adapt to different vehicles.

Description

technical field [0001] The invention relates to a tensioner, in particular to a double-torque variable gear mechanical tensioner. Background technique [0002] An automobile engine usually includes an accessory transmission system. In today's society, more and more accessory transmission systems transmit the power of the automobile engine from the main shaft to the pulleys connected with each accessory through a belt. These accessories usually include air conditioning compressors, water pumps, alternators, hydraulic pumps, power steering, etc. In this accessory drive system, one or more tensioners are usually included. One of the main functions of the tensioner is to provide a certain belt tension for the accessory drive system of the car, so that the belt can smoothly transmit the power of the car engine from the main shaft To the leather pulleys of each accessory without slipping. [0003] When the current tensioner is assembled, the tensioning force of the tensioner is ...
