Abstract
The utility model discloses a tensioning pulley assembly of an engine, which comprises a base, a belt pulley and a tensioning arm. The belt pulley is arranged at one end of the tensioning arm in matched mode, the base is arranged at the other end of the tensioning arm in matched mode, a shaft sleeve is arranged between the base and the tensioning arm in matched mode, and the tensioning arm and the base are connected with each other in matched mode to form a cavity. An elastic part is arranged in the cavity in matched mode and is matched with the base, a groove is arranged on the tensioning arm, and a first gasket and a second gasket are sequentially arranged in the groove in matched mode. Through the mode, the tensioning pulley assembly of the engine is simple in structure and low in production cost, reduces frictional damping and improves durability.
Description
Technical field
The utility model relates to technical field of engines, particularly relates to a kind of engine stretching wheel assembly.
Background technique
Along with the develop rapidly of automobile, belt wheel also is being widely used in tightening belt in the accessory belt transmission system on the motor car engine, realizes effective transmission.Under the overall situation of energy-saving and emission-reduction, low-tension and low frictional loss transmission are the targets that the belt wheel design aspect is pursued, and have adopted spring seat and annular cover to cooperate the main frictional damping that produces in the belt wheel work in traditional belt wheel design.For the loss of reducing friction; When the motor head accessory system does not need high damping to suppress dynamic fluctuation; Should design low damping product as much as possible, save material and reduce cost, reduce weight, simplify the production assemble flow, and satisfy actual use simultaneously.
The model utility content
The technical problem that the utility model mainly solves provides a kind of simple in structure, engine stretching wheel assembly that cost of production is low, can reduce belt wheel weight, reduces frictional damping, has improved endurance quality.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of engine stretching wheel assembly is provided, comprises: base, belt wheel and tension arms; Said belt wheel is equipped with at tension arms one end; Said base is equipped with at the tension arms the other end, is equipped with axle sleeve between said base and the tension arms, and said tension arms and base are connected and constitute a cavity; Be equipped with elastic component in the said cavity; Said elastic component and base match, and have a groove on the said tension arms, are equipped with first pad and second pad in the said groove successively.
In preferred embodiment of the utility model, said belt wheel is connected at tension arms one end through bolt.
In preferred embodiment of the utility model, said first pad is a thrust washer, and said second pad is the front end pad.
In preferred embodiment of the utility model, be provided with a plurality of bearings between said belt wheel and the base, be provided with dust cover between said bearing and the belt wheel.
In preferred embodiment of the utility model, said elastic component is a spring.
The beneficial effect of the utility model is: the utility model engine stretching wheel assembly is simple in structure, cost of production is low, reduces belt wheel weight, reduces frictional damping, has improved endurance quality.
Description of drawings
Fig. 1 is the structural representation of the utility model engine stretching wheel assembly one preferred embodiment;
Fig. 2 be shown in the decomposing schematic representation of engine stretching wheel assembly;
The mark of each parts is following in the accompanying drawing: 1, base, 2, belt wheel, 3, tension arms, 4, cavity, 5, elastic component, 6, groove, 7, first pad, 8, second pad, 9, bearing, 10, dust cover, 11, axle sleeve, 12, bolt.
Embodiment
Below in conjunction with accompanying drawing the preferred embodiment of the utility model is set forth in detail, thereby the protection domain of the utility model is made more explicit defining so that advantage of the utility model and characteristic can be easier to it will be appreciated by those skilled in the art that.
See also Fig. 1 and Fig. 2, a kind of engine stretching wheel assembly comprises: base 1, belt wheel 2 and tension arms 3; Said belt wheel 2 is equipped with at tension arms 3 one ends; Said base 1 is equipped with at tension arms 3 the other ends, is equipped with axle sleeve 11 between said base 1 and the tension arms 3, and said tension arms 3 is connected with base 1 and constitutes a cavity 4; Be equipped with elastic component 5 in the said cavity 4; Said elastic component 5 matches with base 1, has a groove 6 on the said tension arms 3, is equipped with first pad 7 and second pad 8 in the said groove 6 successively.
In addition, said belt wheel 2 is connected at tension arms one end through bolt 12.
In addition, said first pad 7 is a thrust washer, and said second pad 8 is the front end pad.
In addition, said belt wheel 2 is injection-moulded in bearing 9, is provided with dust cover 10 between said bearing 9 and the belt wheel 2.
In addition, said elastic component 5 is a spring.
The utility model engine stretching wheel assembly is fastening through bolt 12 with belt wheel 2 and tension arms 3 right sides; Respectively spring and axle sleeve 11 cooperations are installed on the base 1 again; Cooperate base 1 then to be installed to tension arms 3 left sides, in the groove 6 in tension arms 3 left sides, behind the installation thrust washer front end pad is installed earlier at last, accomplish installation; The frictional damping of belt wheel 2 mainly comes from axle sleeve 11, thrust washer 7 and front end pad 8, has reduced friction.
Be different from existing technology, the utility model engine stretching wheel assembly is simple in structure, cost of production is low, reduces belt wheel weight, reduces frictional damping, has improved endurance quality.
The above is merely the embodiment of the utility model; Be not thus the restriction the utility model claim; Every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the utility model.
