Description
Technical field
The present invention relates to a kind of air-cooling apparatus of motor car engine, especially a kind of side-mounted angle transmission mechanism of car engine cooling fan.
Background technique
At present, in the fan belt driving mechanism drive fan cooling system that existing rear engine vehicle adopts, require the radiator fan axle must be parallel with engine crankshaft, promptly motor and radiator will be arranged side by side, simultaneously open the air port, be sealed into the air channel at body side wall.Can be along with passenger vehicle is equipped with popularizing of high power engine, the also corresponding increase of its water jacket heat dissipating capacity, so the radiator heat-dissipation area of cooling system and the also corresponding increase of requirement of fan diameter, but be subjected to the restriction of car load width and floor level, if fan shaft and engine crankshaft are arranged in parallel, brought significant limitation can for the layout of rear engine vehicle; If the cabin do not had the forced ventilation measure, engine operating temperature will less stable, and oil consumption is higher, and noise and exhaust emission pollution are bigger.Chinese patent publication number: CN 1580512A, open day on February 16th, 2005, the patent of invention that name is called " automobile cooling fan driving mechanism assembly " discloses a kind of fan drive device that can the side fan, and it is made up of driving-shaft assembly, middle wheel assembly, fan drives assembly, fan assembly.Middle wheel assembly is connected with fan drives through transmission shaft, and the fan drives changed course also drives fan assembly and rotates.Realized that fan shaft and engine crankshaft are arranged vertically, and can satisfy the spatial requirement of rear engine vehicle.But driving components such as middle wheel assembly, transmission shaft and the fan drives of this mechanism are rigid members such as axle, coupling and gear, the driven off by shaft noise of gear and transmission is bigger, the lubrication system complexity, installation precision is had relatively high expectations, particularly this device from great, antivibration, shock resistance are relatively poor, when being applied to rear engine vehicle, because jolting, vibrating of vehicle rear is bigger, transmission component is fragile, poor reliability.
Summary of the invention
The present invention mainly solves the existing in prior technology transmission shaft and bearing support is lubricated complicated, the installation precision height, coupling is easy to wear, from great, problems such as resistance to shock difference, provide a kind of good anti-vibration, noise little, easy to install and use, from the angle transmission mechanism of car engine cooling fan of heavy and light.
The technical solution adopted for the present invention to solve the technical problems is: a kind of angle transmission mechanism of car engine cooling fan, comprise fan assembly, fan assembly is connected with the fan belt wheel assembly, fan pulley on the wheel assembly of fan belt is connected with transmission pulley on being arranged on belt pulley angle transmission mechanism assembly through belt, with the perpendicular powered pulley that is provided with of transmission pulley, powered pulley is connected with power plant through power belt on belt pulley angle transmission mechanism assembly.
Belt pulley angle transmission mechanism assembly of the present invention comprises power intake, bearing support and bracket assembly, drive bevel gear, driven wheel of differential, gear shaft, bearing cap, end cap, casing and transmission pulley, drive bevel gear and driven wheel of differential are meshing with each other in casing, gear shaft on the driven wheel of differential is fixed on the casing through bearing cap and end cap, on the gear shaft of casing outside, transmission pulley is installed, the wheel beam warp bearing support and the bracket assembly of drive bevel gear are fixed on the casing, on the drive bevel gear wheel shaft of casing outside powered pulley are installed.
The present invention can also bearing support and bracket assembly be provided with the base fixing frame.
The present invention can also make the fan belt wheel assembly be connected with fan assembly through magnetic clutch.
Fan belt of the present invention wheel assembly comprises belt pulley assembly and fixed base, and fixed base is installed on the automobile chassis.
The present invention can also be equipped with Idle wheel near belt.
Compared with prior art, the invention has the beneficial effects as follows: 1, between belt pulley angle transmission mechanism assembly and fan belt wheel assembly, adopt belt transmission, formation flexibly connects, simple in structure, in light weight, good anti-vibration, noise is low, installation and easy to maintenance, and transmission performance is reliable and stable.2, this mechanism is low to the mounting point required precision of fan and engine crankshaft belt pulley, arranges and debugs conveniently.3, need not change velocity ratio in the gear-box to the transmission speed ratio adjustment, need only change the size of the external diameter of belt pulley, versatility is good.4, this mechanism has realized that cooling fan axle and engine crankshaft are arranged vertically, and has at first solved the problem of complete vehicle structure layout aspect, secondly is the deposit of doing the cooling capacity aspect for high power engine.5 and since intercooler and heat sink side, reduced vehicle space to stacked installation take width and height, increased the flexibility that cooling system arranges and the proximity of motor, reduced greatly by the influence factor in car load space.But also greatly reducing row's height behind the car load, the fuse heat diffusion area that strengthens intercooler and radiator along car load vehicle commander direction will become and be easy to, and help the layout of seat in the vehicle body.6, because the fan side can be cancelled air inlet duct, reduced fan air draught resistance greatly, improve air output, the utmost point is beneficial to and reduces the cooling constant value; And the air draft of fan can also directly be brushed the engine body surface and be improved the heat radiation of the heated oxygen sensor on the outlet pipe; And mandatory reinforcement engine nacelle hot-air convection, improve cabin temperature.
