Technical field
The present invention relates to automobile cooling system technical field, refer to a kind of cooling system of vehicle carrying generator set particularly.
Background technique
At present, Some vehicles is equipped with generator set, namely has two motors, a motor-powered vehicle travels, an engine driven generators generating.There are three kinds of working conditions in two motors, the first operating mode: drive vehicle traveling motor to work independently, the second operating mode: drive electrical power generators motor to work independently, the third operating mode: two simultaneous firings, this operating mode is only applicable to vehicle when travelling on better road surface and have vehicle-speed limit.Because vehicle has higher requirements to acceleration performance and grade climbing performance, therefore vehicle traveling motor is driven to have larger stand-by power, during two simultaneous firings, owing to having vehicle-speed limit, drive vehicle traveling engine load rate lower, therefore cooling require also lower.Due to restricted to generator set volume and weight, available driving electrical power generators engine power is less, when Plain works, generator set generated output meets usage requirement, but when working on plateau, owing to driving electrical power generators engine power to decline, cause generator set generated output not enough.
Summary of the invention
Object of the present invention is exactly the deficiency that will solve above-mentioned background technology, a kind of cooling system of vehicle carrying generator set is provided, two groups of motors are connected by the cooling system of appropriate design by this system, and two motors Shi Junneng that works independently meets respective cooling requirement; During two simultaneous firings, allow by linkage driving mechanism and travel the heat radiation of engine-driving cooling fan help generating engine, reduce the accessory power of generating engine, improve its generated output to meet plateau applying working condition, improve traveling engine load rate simultaneously.
For realizing this object, the cooling system of vehicle of the lift-launch generator set designed by the present invention, comprise generating engine and travel motor, described traveling motor is connected with cooling fan; Main radiator is connected with by water-cooling tube between the pump intake of described traveling motor and water outlet; Secondary radiator is connected with by water-cooling tube between the pump intake of described generating engine and water outlet; Ball valve is connected with by water-cooling tube between the water intake of described main radiator and the water intake of secondary radiator, the water outlet of described main radiator connects the water outlet of one-way valve by water-cooling tube, the water outlet of described secondary radiator connects the water intake of one-way valve by water-cooling tube; Linkage driving mechanism is connected with between the output terminal of described generating engine and the output terminal travelling motor.
Further, described linkage driving mechanism comprises the free wheel device, the first belt pulley be connected with free wheel device, the second belt pulley be connected with the output terminal of generating engine and the belt connecting the first belt pulley and the second belt pulley that are connected with traveling engine output end; Described first belt pulley connects cooling fan.
Further, be also provided with automatic expansion tightening wheel between described first belt pulley and the second belt pulley, automatic expansion tightening wheel walked around by described belt.
Further, described ball valve is ecp ball valve.
The invention has the beneficial effects as follows: traveling motor and dynamo engine share a set of cooling system, reduce the volume and weight of generator set; During two simultaneous firings, cooling fan, by travelling by engine-driving, decreases the accessory power of dynamo engine, improves its generated output, make it meet plateau applying working condition, improves the Rate of load condensate travelling motor simultaneously.

Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
The cooling system of vehicle of the lift-launch generator set as shown in Fig. 1-2, comprise generating engine 6 and travel motor 1, described traveling motor 1 is connected with cooling fan 11; Main radiator 2 is connected with by water-cooling tube 13 between the pump intake of described traveling motor 1 and water outlet; Secondary radiator 3 is connected with by water-cooling tube 13 between the pump intake of described generating engine 6 and water outlet; Ball valve 4 is connected with by water-cooling tube 13 between the water intake of described main radiator 2 and the water intake of secondary radiator 3, the water outlet of described main radiator 2 connects the water outlet of one-way valve 5 by water-cooling tube 13, the water outlet of described secondary radiator 3 connects the water intake of one-way valve 5 by water-cooling tube 13; Linkage driving mechanism is connected with between the output terminal of described generating engine 6 and the output terminal travelling motor 1.
In technique scheme, described linkage driving mechanism comprises the free wheel device 12 be connected with traveling motor 1 output terminal, the first belt pulley 8 be connected with free wheel device 12, the second belt pulley 14 be connected with the output terminal of generating engine 6 and connects the belt 9 of the first belt pulley 8 and the second belt pulley 14; Described first belt pulley 8 connects cooling fan 11.
In technique scheme, be also provided with automatic expansion tightening wheel 10 between described first belt pulley 8 and the second belt pulley 14, automatic expansion tightening wheel 10 walked around by described belt 9.
In technique scheme, described ball valve 4 is ecp ball valve.
Embodiment one: travel motor 1 and work independently.Cooling fan 11 is driven by traveling motor 1; Ecp ball valve 4 is opened, cooling water pumps by travelling motor 1 water pump, one tunnel returns through main radiator 2 and travels motor 1 water pump, another road returns through ecp ball valve 4, secondary radiator 3 and one-way valve 5 successively and travels motor 1 water pump, circulating successively, realizing the cooling to travelling motor 1.Because main radiator 2 and secondary radiator 3 work simultaneously, requirement when travelling the larger operating mode of motor 1 heat dissipating capacity can be met.
Embodiment two: generating engine 6 works independently.Cooling fan 11 is driven by the second belt pulley 14, automatic expansion tightening wheel 10, free wheel device 12 by generating engine 6; Cooling water is pumped by generating engine 6 water pump, returns generating engine 6 water pump, circulates successively, realize the cooling to generating engine 6 through secondary radiator 3.
