Description
Technical field
This utility model relates to technical field of automobile, particularly relates to engine wheel system accessory technical field, is specifically related to a kind of automatic tensioner.
Background technology
Regulating wheel is the tensioner of V belt translation, can be by use is fixing or self-regulated regulating wheel realizes.Regulating wheel is typically located at the inner side of slack list, so that band is only by bend in one direction；Meanwhile, for ensureing that small pulley cornerite will not reduce too much, regulating wheel should be installed close proximity to big belt wheel.When using fixing regulating wheel, the change in size produced due to elongation and the abrasion thermal coefficient of expansion different with electromotor fuselage and belt of life span inner belt so that electromotor tensile force in operation process is the most unstable.When the centre-to-centre spacing of belt can not regulate, regulating wheel can be used band tensioning.If tensile force is excessive, driving means is prone to produce noise and belt life shortens；If tensile force is too small, belt easily skids, vibrates generation noise, and belt is prone to wrinkling, damaged, thus the lost of life.Regulating wheel plays the most important effect in the drive system of automobile engine as can be seen here.
The Chinese utility model patent application of Patent No. ZL201220444243.0 of the applicant's earlier application discloses a kind of automatic tensioner, including body (1), support plate (2), spring (3), belt pulley (12), axle bolt (14), bearing (16), linking arm (19), rotary middle spindle (18), described body (1) is provided with installation pin, the recessed groove (17) along the circumferencial direction installing pin is offered on described body (1), although this automatic tensioner avoids the interference when assembling with pin control hole, decrease the parallelism error of automatic tensioner and the electromotor installation base surface caused because of Assembly Interference, improve the coplanarity of regulating wheel and train, product is normal for service life, it is easy to engine assembly employee and is easily assembled belt.But, when the support plate of this automatic tensioner can not bear bigger load, long-time use, body easily comes off.
And for example, the Chinese utility model patent application of Patent No. ZL201420723305.0 of the applicant's earlier application discloses a kind of automatic tensioner, including the belt pulley (3) being arranged on support (5), body (2) and spring (1), the installed surface of support (5) is fixedly connected with the sleeve (6) running through support (5)；Sleeve (6) is outwardly hollow-core construction；Offering axial installation gap (7) on the circumference wall of jacket casing (6), spring (1) is wrapped in upper and spring (1) the one end of jacket casing (6) and is connected to install in gap (7), and the other end is connected on body (2) in the limited mouth (2.4) offered.This tension wheel structure advantages of simple, assemble firm, lighter weight, be hardly damaged.But, this regulating wheel can not bear bigger load, when using for a long time, and its internal each component wear is relatively big, easy premature breakdown.
