Description
Technical field
The present invention relates to vehicle cooling technology field, be specially a kind of commercial car and join retarder flow
Regulation valve.
Background technology
Commercial car Retarder flow control valve uses the common wax of engine-cooling system at present
Formula thermoregulator, coolant flows through the retarder being furnished with dedicated heat exchanger the most afterwards, then from electromotor
Return to car load radiator and participate in circulation.The performance of common wax formula thermoregulator is determined by expanding material, expands
Volumetric expansion after absorbed outside energy, produces power, and valve starts to open at, until valve is complete
Opening, the time needs about 90S.And instantaneous generation substantial amounts of heat during retarder braking, high-grade system
The heat produced time dynamic reaches tens kilowatts.Common thermoregulator valve cannot instantaneous be opened, and coolant cannot
Take away amount of heat.During retarder braking, in order to avoid top grade braking produces amount of heat, and protect
Retarder.Conventional method is to reduce gear braking.Because the heat of gear low generation during retarder braking
Amount is few.But, by retarder downshift mode of braking, for driver, easily produce maloperation,
And the faults such as retarder damage occur.Thermoregulator is connected with retarder simultaneously, and coolant flow resistance is big,
Pump power is big, and energy expenditure is big.
Summary of the invention
A kind of radiating rate is fast, can reduce automobile to the invention aims to overcome above-mentioned deficiency to provide
The commercial car of oil consumption joins retarder flow control valve.
The present invention includes housing, also includes the cooling-water temperature sensor for gathering engine water temperature, for receiving
The automobile ECU of collection cooling-water temperature sensor water temperature signal, and for controlling the executor of motor action, described
It is provided with the first valve for controlling retarder mouth flow in housing, follows for controlling the size of electromotor
Second valve of circulation and the valve seat between the first valve and the second valve, described first
Valve and the second valve are coaxially arranged, are provided with motor outside described housing, and described motor output shaft passes through
Leading screw respectively be fixed on the first nut of the first valve central authorities and be fixed on that the second valve is central second
Nut matches.
The present invention collects engine water temperature sensor water temperature signal by ECU, by pre-setting control program
Executor control motor rotate, promote the first valve and the second valve come control valve open size,
Thus regulate the flow of systemic circulation, maintain engine water temperature, preferably protect electromotor, play reduction
Automobile fuel consumption, reduces the effect of the discharge of CO, HC in tail gas.Simultaneously by collecting retarder braking letter
Number, ECU, rotates by controlling motor by executor according to the relevant information pre-set, and promotes the
Systemic circulation mouth is closed by one valve and the second valve, opens retarder mouth simultaneously, makes coolant flow through slow
Speed device, takes away the amount of heat that retarder braking produces, protects retarder.

Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment further illustrates the present invention.
Embodiment: the present invention includes housing, also includes the cooling-water temperature sensor for gathering engine water temperature
9, for collecting the automobile ECU 10 of cooling-water temperature sensor 9 water temperature signal, and it is used for controlling motor action
Executor 11, be provided with in described housing the first valve 1 for controlling retarder mouth flow, for
Control the second valve 4 of the large and small cycles flow of electromotor and be positioned at the first valve 1 and the second valve
Valve seat 3 between 4, described first valve 1 is coaxially arranged with the second valve 4, installs outside described housing
Have motor 7, described motor 7 output shaft by leading screw 8 respectively be fixed on the of the first valve 1 central authorities
One nut 12 and the second nut 13 being fixed on the second valve 4 central authorities match.Described housing is by upper cover
Body 2 and lower cover 6 form, described housing be provided with retarder mouth, cooling liquid inlet, radiator mouth and
Partial circulating mouth, described valve seat 3 is arranged on lower cover 7 for controlling cooling liquid inlet and radiator mouth
Break-make, described first valve 1 and the second valve 4 are respectively equipped with the first cylindrical drum shell 14 and second
Cylindrical drum shell 15, described first cylindrical drum shell 14 and the second cylindrical drum shell 15 two ends are through and
The first bracing ring 16 and the second bracing ring 17, described upper outlet body 2 and lower cover 6 it is respectively equipped with on inwall
Being respectively equipped with the first guide collar 18 and the second guide collar 19 on inwall, described second guide collar 19 is used for
Cutting off radiator mouth and partial circulating mouth, described partial circulating mouth is arranged over for controlling partial circulating mouth flow
Sealing plate 20, described first cylindrical drum shell 14 and the outer wall edge respectively of the second cylindrical drum shell 15
First guide collar 18 and the second guide collar 19 slide axially thus regulate radiator mouth and partial circulating mouth
Uninterrupted, described first nut 12 and the second nut 13 are separately fixed at the first bracing ring 16 and
On two bracing rings 17.Described second guide collar 19 is provided with for preventing the second valve 4 side leakage
Sealing ring 5.Described first nut 12 is coaxial with the first valve 1, described second nut 13 and second
Valve 4 is coaxial.
Motor 7 rotarily drives the second valve 4 and moves, thus controls the large and small circulation of electromotor；With
Time motor 7 rotarily drive the first valve 1 and move, control retarder mouth coolant rate, retarder mouth
In order to ensure there are enough flows by retarder after opening, need to simultaneously close off electromotor systemic circulation,
I.e. first valve 1 contacts with valve seat 3, and electromotor systemic circulation is closed, and coolant flows to retarder mouth.
Coolant all by entering systemic circulation after retarder, returns to radiator.Sealing ring 5 is fixed on lower cover
On body 6, seal the second valve 4 surrounding leakage, reduce partial circulating flow after systemic circulation is opened.Motor 7
With controlling executor.According to ECT signal, automobile ECU provides dependent instruction,
Rotarily drive the first valve 1 by actuator driven motor and the second valve 4 moves, along with electromotor
Water temperature rises, and the second valve 4 moves to open maximum, and coolant rate is maximum, then cools down liquid temperature
Degree reduces, and automobile ECU provides instruction, and motor 7 rotates the second valve 4 and falls after rise, and lift reduces, and sends out
Motivation water temperature is finally reached balance.When automobile ECU receives retarder braking instruction, motor 7 quickly drives
Dynamic first valve 1 and the second valve 4, cuts off electromotor systemic circulation, makes coolant all by retarder,
Take away the amount of heat because producing when retarder is braked, thus protect retarder.Automobile ECU is not received
During to retarder braking instruction, coolant, without retarder, directly walks engine size circulation, fall
Low pump Energy consumption.Hydraulic type retarder flow control valve of the present invention can reduce in automobile
Oil consumption, in tail gas, CO discharge declines, and HC discharges decline, simultaneously works as protecting the effect of Retarder.
When the first valve 1 rises to the highest and time the second valve 4 contacts with valve seat 3, and retarder mouth is shut,
Coolant flows to partial circulating mouth by the second cylindrical drum shell 15；When the first valve 1 rise to the highest and
When second valve 4 contacts with sealing plate 20, coolant flows to radiator mouth.
Above-described embodiment is the present invention preferably embodiment, but embodiments of the present invention are not by upper
Stating the restriction of embodiment, that is made under other any spirit without departing from the present invention and principle changes
Become, modify, substitute, combine, simplify, all should be the substitute mode of equivalence, be included in the present invention
Protection domain within.
