Abstract
The utility model discloses a front end wheel device of a centrally-mounted fan engine, solving the problems that the distribution of the fan on the existing engine is not reasonable and the cooling performance to the engine is poorer. The front end wheel device has the advantages that the structure is simple, the use is convenient and the cooling performance of the engine is improved by reasonable design of the fan position on the engine. The structure thereof is as follows: a fan bracket assembly is arranged between a crankshaft assemble and a water pump assembly, and comprises a fan belt wheel, a fan bracket and a connecting device of the fan belt wheel and the fan bracket (such as a bearing, a sealing piece and the like); the fan belt wheel is also connected with a tensioning device and a crankshaft belt wheel respectively by a ribbed belt I; and simultaneously the fan bracket assembly is also connected with an engine cylinder by the water pump assembly.
Description
Technical field
The utility model relates to a kind of mid-Duct-Burning Turbofan front end train wheel apparatus.
Background technique
On after market, superheating phenomenon appears in the part vehicle at present.Because fan is contained on the bent axle, so rotation speed of the fan and motor speed ratio are 1: 1 on the motor.From improving the engine cooling ability, the associated part of engine-cooling system will improve to improve the engine-cooling system performance.
Summary of the invention
The utility model be exactly for the layout that solves fan on the present motor unreasonable, to the relatively poor problem of the cooling performance of motor, provide a kind of simple in structure, easy to use, by appropriate design, to improve the mid-Duct-Burning Turbofan front end train wheel apparatus of engine cooling performance to position of fan on the motor.
For achieving the above object, the utility model adopts following technological scheme:
A kind of mid-Duct-Burning Turbofan front end train wheel apparatus, its structure is: the fan bracket assembly is arranged between crank assemblby and the water pump complement, comprises fan pulley, fan bracket, the connection set of fan pulley and fan bracket; Fan pulley also is connected with crank pulley with tension device respectively by poly Vbelt belt I; Fan bracket also is connected with engine cylinder-body by water pump complement simultaneously.
Described tension device is Idle wheel I, and it is installed on the air compressor gear cap, and is connected with poly Vbelt belt I.
Described fan bracket is fixed on the engine cylinder-body by the water pump body of water pump complement.
Described water pump complement is provided with water pump pulley, and water pump pulley is connected with crank pulley by poly Vbelt belt II; Poly Vbelt belt II is by the Idle wheel II tensioning on the tension cushion block; The tension cushion block is fixed on the engine cylinder-body by housing for timing gear.
Described water pump pulley also is connected with poly Vbelt belt III, poly Vbelt belt III then be fixed on the air-conditioning carriage on generator be connected with air-conditioning.
Mid-Duct-Burning Turbofan of the present utility model is arranged and is comprised a fan bracket assembly, has parts such as bearing, Sealing that fan pulley is connected with fan bracket in the fan bracket assembly.The fan pulley of fan bracket assembly is connected with crank pulley by poly Vbelt belt I.Poly Vbelt belt I comes tensioning by the Idle wheel I on the air compressor gear cap.The fan bracket assembly is fixed on the engine cylinder-body by the water pump body of water pump complement.The power that crank pulley passes over drives fan pulley by the bearing in the fan bracket assembly and rotates, and then fan is rotated.The water pump pulley of water pump complement is connected with crank pulley by poly Vbelt belt II.Poly Vbelt belt II is by the Idle wheel II tensioning on the tension cushion block.The tension cushion block is fixed on the engine cylinder-body by housing for timing gear with the bolt of two M8.Generator and air-conditioning are fixed on the air-conditioning carriage, connect by the belt pulley of poly Vbelt belt with water pump complement.Generator and air-conditioning can be adjusted tensioning by turnbuckle separately.
The beneficial effects of the utility model are: when engine blower was contained on the bent axle, the fan speed ratio was 1: 1.In order to improve the fan speed ratio, position of fan is arranged in the middle of bent axle and the water pump, by a fan bracket assembly, fan is connected with poly Vbelt with bent axle.Like this, the fan speed ratio rises to 1.16: 1, and rotation speed of the fan has improved 16%.Because air quantity, the blast of fan are directly proportional with first power, the quadratic power of rotation speed of the fan, therefore improving rotating speed is the effective ways that increase air quantity and blast, and rotation speed of the fan improves better for improving engine overheat phenomenon effect like this.The speed ratio of water pump remains unchanged, and impeller profile etc. do not change yet, and only changes the profile of water pump body, and satisfying installation requirement, so the water pump cooling performance remains unchanged.It is basic identical with other WD615 product spaces that air-conditioning position and generator position keep, and guaranteed the versatility of product.By above design and layout, further cooperate car load to arrange and will the cooling performance that improve car load be played a role simultaneously.
