Abstract
The utility model relates to a transmission technical field especially relates to a two -way tensioning ware, connecting first take -up pulley (3) on tensioning assembly (2) and rotating second take -up pulley (4) connected on first fixing base (1) including first fixing base (1), setting tensioning assembly (2), the rotation on first fixing base (1), it still includes fixes second fixing base (5) on the engine, first fixing base (1) is rotated and is connected on second fixing base (5). This kind of two -way tensioning ware can be applicable to hybrid engine.
Description
Technical field
This utility model relates to technical field of transmission, particularly relates to a kind of Dual directional tightener.
Background technology
Tensioner is holding means conventional on belt, chain transmission system, is characterized in keeping belt, chain in transmission
During can have suitable tensile force, thus avoid belt creep, or avoid Timing Belt occur to jump tooth, de-tooth and haul out,
Or prevent chain-loose, come off, alleviate sprocket wheel, chain wear.
But the stretcher being applied to dynamo belt of prior art mainly includes fixing consolidating on the engine
Reservation, be arranged on fixing seat side tension assembly and be arranged on fixing seat opposite side rotation wheel, this structure is applicable to
Fuel engines, but because only that the tension assembly being arranged on fixing seat side has regulatory function, and it is arranged on fixing seat
The rotation wheel of opposite side does not has regulatory function, and both can not exchange, but is because fuel engines and is only come by oil
Drive, so a kind of power, and hybrid power engine uses oil or electricity to drive, so there being two kinds of power, and two power
And differ, so the stretcher of this structure of prior art is just not suitable for hybrid power engine, if hybrid power starts
Machine uses the stretcher of this structure, and effective power transmission efficiency can reduce.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of can be suitably used for hybrid power engine two-way
Tight device.
This utility model be the technical scheme is that a kind of Dual directional tightener, including first fixing seat, being arranged on first
Tension assembly, the first regulating wheel being rotatably connected on tension assembly on fixing seat and be rotatably connected on first and fix on seat
The second regulating wheel, it also include fixing on the engine second fix seat, described first fixes seat is rotatably connected on second
On fixing seat.
Using above structure compared with prior art, this utility model has the advantage that fixes seat and second by first
Being rotationally connected between fixing seat, such tension assembly is the most not just for regulation the first regulating wheel, moreover it is possible to by the first fixture
And second fixture regulate the second regulating wheel, so regulation effect of getting up is more preferable, adapts on hybrid power engine
Use so that its effective power transmission effect is higher.
As preferably, described second fixes seat is provided with annular protrusion, and described first fixes seat is provided with and annular protrusion
The through hole matched, described annular protrusion stretches into and is additionally provided with lining between through hole, and the outer wall of described annular protrusion and the inwall of through hole
Set.First fixes seat and second fixes and uses this rotational structure between seat, and rotating effect is preferable, and because being provided with lining,
Frictional force is less between the two, and then makes tension assembly can preferably go to regulate the second regulating wheel.
As preferably, described tension assembly includes
Base, is fixed on first and fixes on seat；
Turning arm, is rotatably connected on base, and is rotationally connected for the first regulating wheel；
Spring, between described base and turning arm, spring upper end end face contacts with turning arm, lower spring end end face with
Base contacts, is used for biasing described turning arm and makes it inside contract direction motion towards described spring；
Damping piece, circumference spacing on turning arm and and base contacts, for provide stop turning arm rotate friction resistance
Buddhist nun's power；
Bracing frame, is arranged between spring and damping piece and fixes with damping piece, is used for preventing from directly extruding resistance because of spring
Damping member and make damping piece damage.
Use this tension assembly, drive spring to inside contract this work turning arm time in running order for original tensioner
Changing the turning arm when tensioner is in running order into as state drives spring to extend out, i.e. so turning arm and spring upper end
End contact force, so being not required to set up bending hook, the most also spring torsion will be caused to decline because of having used long
Subtracting, tensile force is not easy to lose efficacy so that the using effect of spring is preferably and service life is higher.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model Dual directional tightener.
Fig. 2 is the exploded perspective view of this utility model Dual directional tightener.
As shown in the figure: 1, first fix seat；2, tension assembly；3, the first regulating wheel；4, the second regulating wheel；5, second fix
Seat；6, annular protrusion；7, through hole；8, lining.
