Description
Technical field
The utility model relates to the layout of a kind of novel hydrodynamic retarder in car load transmission system, is applicable to heavy truck auxiliary braking field.
Background technique
At present, the hydrodynamic retarder of domestic most heavy truck coupling is connected on speed changer, adopts the mode of serial or parallel connection.Required braking moment is large, and weight is large, and volume is large and cost is high, and need mate corresponding speed changer, the construction cycle is long, also needs to change driveline arrangement, causes hydrodynamic retarder application on heavy trucks the driver to have significant limitation.
Summary of the invention
For the problems referred to above, the purpose of this utility model is to provide the layout of a kind of novel hydrodynamic retarder in car load transmission system, for meeting auxiliary braking demand, need to develop a hydrodynamic retarder and realize auxiliary brake function, and meet little on transmission system impact, coupling is simple, the demands such as cost is low, lightweight, and the construction cycle is short.
The technical solution of the utility model is achieved in that the layout of a kind of novel hydrodynamic retarder in car load transmission system, is made up of radiator, motor, speed changer, hydrodynamic retarder body, heat exchanger, motor thermostat, water pump, external thermostat, oil cooling service pipe, oil temperature sensor temperature, cooling-water temperature sensor; It is characterized in that: hydrodynamic retarder assembly is formed by connecting by oil pipe by hydrodynamic retarder body and heat exchanger, hydrodynamic retarder assembly is connected in parallel on the engine torque extraction mouth place of car load transmission system, hydrodynamic retarder body and heat exchanger are connected by oil cooling service pipe by hydrodynamic retarder assembly, oil temperature sensor is fixed on oil pipe, heat exchanger connects external thermostat, external thermostat one termination radiator, heat exchanger is got back to through water pump, realizing the complete radiation system of hydrodynamic retarder, is the major cycle of cooling line; External thermostat the other end water pump, get back to heat exchanger, form short circle, do not dispel the heat, the outside external thermostat of hydrodynamic retarder assembly is bolted on motor body, and water route is metal winding pipe, suitably arranges with Full Vehicle System space, cooling-water temperature sensor is positioned at heat exchanger water outlet, to monitor water temperature.
The car load transmission system of what good effect of the present utility model was brand-new install additional hydrodynamic retarder, hydrodynamic retarder is arranged in the front end of car load transmission system, be positioned at engine torque extraction mouth place, the braking moment that hydrodynamic retarder produces enters transmission system through speed changer amplification, realize auxiliary brake function, effectively reduce the braking moment of hydrodynamic retarder design, change little to transmission system, coupling is simple, shortens the construction cycle etc.
Accompanying drawing explanation
Fig. 1 is that car load of the present utility model installs hydrodynamic retarder transmission system schematic diagram additional.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described: as Fig. 1, novel hydrodynamic retarder, at a layout for car load transmission system, is made up of radiator 1, motor 2, speed changer 3, hydrodynamic retarder body 4, heat exchanger 5, motor thermostat 6, water pump 7, external thermostat 8, oil cooling service pipe 9, oil temperature sensor temperature 10, cooling-water temperature sensor 11; It is characterized in that: hydrodynamic retarder assembly is formed by connecting by oil pipe by hydrodynamic retarder body 4 and heat exchanger 5, hydrodynamic retarder assembly is connected in parallel on the engine torque extraction mouth place of car load transmission system, hydrodynamic retarder body 4 and heat exchanger 5 are connected by oil cooling service pipe 9 by hydrodynamic retarder assembly, oil temperature sensor 10 is fixed on oil pipe 9, heat exchanger 5 connects external thermostat 8, external thermostat 8 one termination radiator 1, heat exchanger 5 is got back to through water pump 7, realizing the complete radiation system of hydrodynamic retarder, is the major cycle of cooling line; External thermostat 8 the other end water pump 7, get back to heat exchanger 5, form short circle, do not dispel the heat, the outside external thermostat 8 of hydrodynamic retarder assembly is bolted on motor body, and water route is metal winding pipe, suitably arranges with Full Vehicle System space, cooling-water temperature sensor 11 is positioned at heat exchanger water outlet, to monitor water temperature.
When hydrodynamic retarder body 4 does not work, water temperature is not high, and external thermostat 8 controls water route and walks short circle, water pump 7.When hydrodynamic retarder 4 is started working, produce a large amount of heat energy while producing braking moment, and heat-energy losses is controlled by external thermostat 8, major cycle is walked in water route, to water pump 7 after cooling water tank 1, realizes the thermolysis of hydrodynamic retarder in work.The effect of oil temperature sensor detects hydrodynamic retarder assembly working oil temperature, and after exceeding permission oil temperature, hydrodynamic retarder assembly is quit work automatically by electric control system controls, is in normal temperature range all the time to protect Full Vehicle System work.Effectively by its independently oil cooler system radiating connect into the cooling system of car load.
Meet the demand of the auxiliary braking of car load transmission system, solve cost declining, loss of weight and space are arranged and are mated the problems such as difficulty, innovate first and adopt new way in car load transmission system, realize the auxiliary brake function being arranged on the hydrodynamic retarder at engine torque extraction mouth place, at home and abroad field all belongs to innovation, has shown technological advancement.
