System.
Background technology
At present, generating set is equipped with Some vehicles, that is, there are two engines, a motor-powered vehicle travels,
One engine driven generators generates electricity.Three kinds of working conditions, the first operating mode be present in two engines:Vehicle traveling is driven to use
Engine works independently, second of operating mode:Driving electrical power generators are worked independently with engine, the third operating mode:Two are started
Machine works simultaneously, this operating mode be only applicable to vehicle travel on preferable road surface and with speed limitation in the case of.Due to vehicle pair
Acceleration and grade climbing performance have higher requirements, therefore drive vehicle traveling engine to possess larger stand-by power, two hairs
Motivation works simultaneously when, due to being limited with speed, driving vehicle traveling engine load rate it is relatively low, therefore cooling requirement also compared with
It is low.Due to restricted to generating set volume and weight, available driving electrical power generators are smaller with engine power, flat
When being worked in original, generating set generated output meets requirement, but when being worked on plateau, because driving electrical power generators are used
Engine power declines, and causes generating set generated output insufficient.
The content of the invention
Present invention aim to solve the deficiency of above-mentioned background technology, there is provided a kind of vehicle of carrying generating set is cold
Two groups of engines are connected by but system, the system by the cooling system of rational design, equal energy when two engines work independently
Meet respective cooling requirement;During two simultaneous firings, traveling engine driving can be allowed to cool down by linkage driving mechanism
Fan helps generating engine radiating, reduces the accessory power of generating engine, improves its generated output to meet that plateau makes
With operating mode, while improve traveling engine load rate.
In order to achieve this, the cooling system of vehicle of the carrying generating set designed by the present invention, including generating engine
With traveling engine, the traveling engine is connected with cooling fan;The pump intake and delivery port of the traveling engine
Between main radiator is connected with by cooling water pipe;Pass through cooling between the pump intake and delivery port of the generating engine
Water pipe is connected with secondary radiator;Connected between the water inlet of the main radiator and the water inlet of secondary radiator by cooling water pipe
There is ball valve, the delivery port of the main radiator connects the delivery port of check valve, the water outlet of the secondary radiator by cooling water pipe
Mouth connects the water inlet of check valve by cooling water pipe;The output end of the generating engine and the output end of traveling engine it
Between be connected with linkage driving mechanism.
Further, the linkage driving mechanism includes the freewheel clutch being connected with traveling engine output end and surpassed
More the first belt pulley of clutch connection, the first belt of the second belt pulley and connection being connected with the output end of generating engine
The belt of wheel and the second belt pulley;First belt pulley connects cooling fan.
Further, automatic expansion tightening wheel is additionally provided between first belt pulley and the second belt pulley, the belt bypasses
Automatic expansion tightening wheel.
Further, the ball valve is ecp ball valve.
The beneficial effects of the invention are as follows:Traveling shares a set of cooling system with engine and dynamo engine, reduces
The volume and weight of generating set;During two simultaneous firings, cooling fan reduces hair by traveling engine driving
The accessory power of dynamo engine, its generated output is improved, it is met plateau applying working condition, while improved traveling and start
The rate of load condensate of machine.
