The utility model provides a passenger train and leading engine cooling fan arrangement structure of truck, includes fan leaf (1), fan axle (2), fan pulley (3), take-up pulley regulation pole (4), fan axle support (5), take-up pulley (6), frame (7), belt (8), crank pulley (9), angle adjusting lever (10), fan axle (2) on install fan leaf (1) and fan pulley (3), fan axle (2) install on fan axle support (5), fan axle support (5) are articulated with frame (7) through bolt (13), angle adjusting lever (10) one end links to each other with fan axle support (5), and the other end links to each other with frame (7). Because the fan shaft is arranged on the frame, the mounting size of the fan shaft relative to the center of the water tank can be adjusted, so that the center of the fan is coincided with the center of the radiator, the cooling efficiency of the fan is improved, and the problem of cracking of the cylinder cover is solved.
Description
Technical field
The utility model relates to a kind of cooling system for motor vehicle layout, relates in particular to a kind of passenger vehicle and truck front-mounted engine cooling fan layout.
Background technique
Motor Vehicle is converting chemical energy in the process of mechanical energy to, has quite a few energy to be converted into heat energy, and this part heat energy can cause engine failure if can not leave.For the protection motor, motor is worked in suitable temperature, therefore, the cooling system of Motor Vehicle must be arranged, the groundwork of cooling system is that heat is dispersed in the air to prevent engine overheat.In the cooling system of Motor Vehicle, the radiator of motor and cooling fan two parts that are absolutely necessary, and also the mutual layout of these two parts is also most important to the cooling effect of motor.
Traditional passenger vehicle and truck front-mounted engine cooling fan layout be with cooling fan cloth directly be arranged on the engine crankshaft or water pump spindle on, there is following shortcoming in this arrangement:
1) receives the restriction that car load is arranged and motor self is arranged; When cooling fan of engine is arranged on the engine crankshaft; Fan center is starkly lower than tank center perhaps when cooling fan of engine is arranged on the water pump spindle; Fan center is apparently higher than tank center, makes that fan can only inswept very limited radiator area, and the efficient of fan reduces.
2) because engine speed and pump rotary speed are certain at a certain operating point, so when cooling fan was put on engine crankshaft perhaps on the water pump spindle, its rotating speed also was nonadjustable, this has just brought difficulty to energy-saving and noise-reducing.
3) when fan is arranged on the water pump spindle, strengthened the load of water pump spindle, cause water pump early failue, accident rate obviously improves.
Deficiency to traditional passenger vehicle and the existence of truck front-mounted engine cooling fan layout; Existing technology has been made improvement, like the Chinese patent publication number: CN 101158308A, open day: on April 9th, 2008; Patent of invention title: " a kind of mounting mechanism of engine blower "; It is characterized in that at the cylinder head front-end face connecting plate being installed, the fan spindle bearing base member is fixed on the connecting plate, and fan pulley and fan fastening flange are installed in respectively on the fan spindle bearing base member.This embodiment of existing technology, though can solve 3 deficiencies of traditional passenger vehicle and the existence of truck front-mounted engine cooling fan layout; The cylinder head front-end face is installed connecting plate, has increased the extra load of cylinder head, has not only increased the complexity of the manufacturing of cylinder head; And in use; Because the imbalance of the extra load of cylinder head under the heat load situation has influence on the rigidity of cylinder head, even cause cylinder head cracking problem.
Summary of the invention
The purpose of the utility model is the deficiency that overcomes existing passenger vehicle and the existence of truck front-mounted engine cooling fan layout; The imbalance of the extra load of cylinder head under the heat load situation; Have influence on the rigidity of cylinder head, even cause cylinder head cracking problem, provide a kind of simple in structure; Easy to maintenance, and adjustable a kind of passenger vehicle and the truck front-mounted engine cooling fan layout of fan center.Its component are few, do not influence motor and cylinder head intensity, and fan center overlaps with the radiator center.
For realizing above-mentioned purpose; The technological scheme that the utility model adopts is: a kind of passenger vehicle and truck front-mounted engine cooling fan layout; Comprise fans, fan shaft, fan pulley, Idle wheel adjustable lever, fan shaft support, Idle wheel, vehicle frame, belt, crank pulley, angle adjustment bar, tensioner lever; Fans and fan pulley are installed on the described fan shaft, it is characterized in that: described fan shaft is installed on the fan shaft support, and the fan shaft support is hinged through bolt and vehicle frame; Angle adjustment bar one end links to each other with the fan shaft support, and the other end links to each other with vehicle frame.
The intermediate support place of said fan shaft support and tensioner lever is hinged, and an end of tensioner lever connects Idle wheel, and the other end connects the Idle wheel adjustable lever.
It is secondary to be provided with the threaded adjusting of being made up of screw and screw rod on described Idle wheel adjustable lever and the angle adjustment bar.
Described angle adjustment rod axis is vertical with the hinging shaft of fan shaft support.
Compared with prior art, the beneficial effect of the utility model is: 1. the fan shaft support links to each other with vehicle frame through bolt, can not have influence on the rigidity of cylinder head, has stopped cylinder head cracking problem.2. because fan shaft is mounted on the vehicle frame, can adjust the installation dimension of fan shaft with respect to tank center, make fan center overlap with the radiator center, the inswept radiator of fan area as much as possible has improved the cooling effectiveness of fan.3. can adjust the speed ratio of fan shaft very easily, select the fan of the little rotating speed of major diameter for use, reach the purpose of energy-saving and noise-reducing.4. reduce the load of water pump spindle, avoided the early failue of water pump.
