Description
Technical field
The utility model relates to automotive engine applications, especially relates to a kind of automobile engine water pump drive unit.
Background technique
Traditional engine water pump is belt drives, and water pump works with the running of motor always.Car load initial start stage, needs engine temperature to raise rapidly and carries out warming-up, to meet good function of the engine and emission request, especially when winter, external environment was lower, more needs motor temperature within the shortest time to raise.In engine-cooling system; generally be provided with large and small cycles; when engine start; heat up as early as possible in order to motor can be made; usually the passage towards radiator can be closed; make the cooling water in engine water jacket be pressed into engine water jacket by water pump again, now cooling water does not flow through radiator, only between water jacket and water pump, carries out short circle.But utilize short circle still comparatively slow to the speed of carrying out warming-up, had electronically controlled water pump product for this problem at present, directly by ECU, pump rotary speed has been controlled, its level of integration is higher, development cost increases, and it is comparatively large to cause engine body to be changed, and the construction cycle increases.
Model utility content
The utility model is to overcome above-mentioned deficiency of the prior art, water air pump inoperative when providing a kind of engine start thus make the automobile engine water pump drive unit of motor rapid warming-up.
To achieve these goals, the utility model is by the following technical solutions:
A kind of automobile engine water pump drive unit of the present utility model, comprise crank pulley, water pump drive wheel, friction wheel and belt, described crank pulley is connected with the bent axle of motor, described belt carries out transmission around crank pulley and friction wheel, motor is provided with the actuator that friction wheel can be driven to be subjected to displacement, make friction wheel take turns Contact Transmission with water pump drive or be separated, motor is also provided with belt adjusting mechanism, comprise can actuator drive under rotate rotating turret, described rotating turret be provided with can with the Idle wheel of belt contacts.Like this, motor just started need warming-up time, when friction wheel and water pump drive are taken turns and be separated by actuator, water pump does not operate, thus engine body temperature is raised rapidly; At the end of warming-up, actuator promotes friction wheel to be made it to take turns with water pump drive to contact, and water pump can run well.In warming-up process, actuator makes rotating turret rotate simultaneously, and the Idle wheel on rotating turret is reduced for the tension force of belt, thus compensates the amount of tension of belt, reduces the loss for belt.
As preferably, described friction wheel is provided with friction wheel support, and described friction wheel support is provided with directional post, and the lower end of described rotating turret is provided with the guide groove matched with directional post.Like this when friction wheel generation relative displacement, rotating turret also can rotate under friction wheel support effect, thus Idle wheel is reduced for the tension force of belt.
As preferably, the upper end of described rotating turret is provided with the wheel carrier be rotationally connected, and described Idle wheel is arranged on the left end of wheel carrier, is provided with holddown spring between the right-hand member of described wheel carrier and rotating turret.Make Idle wheel provide suitable tension force to belt by holddown spring, certain compensation rate can be provided after belt uses a period of time simultaneously, ensure that V belt translation is stable and carry out.
As preferably, the direction of displacement that described friction wheel and water pump drive are taken turns overlaps with the radial direction that water pump drive is taken turns, friction wheel and water pump drive take turns between radial maximum displacement be 5 ~ 10mm.
Therefore, the utility model has following beneficial effect: reduce engine start warm-up period, improves the burning quality of engine idle, improves the service behaviour of motor.
Accompanying drawing explanation
Fig. 1 is the structural representation under the utility model contact condition;
Fig. 2 is the structural representation under the utility model separated state.
In figure, belt 1, Idle wheel 2, wheel carrier 3, holddown spring 4, rotating turret 5, guide groove 501, friction wheel 6, water pump drive wheel 7, friction wheel support 8, directional post 9, crank pulley 10, actuator 11.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
In embodiment as shown in Figure 1, a kind of automobile engine water pump drive unit, comprises crank pulley 10, water pump drive wheel 7, friction wheel 6 and belt 1.Crank pulley is connected with the bent axle of motor, belt carries out transmission around crank pulley and friction wheel, motor is provided with actuator 11, actuator can adopt solenoid valve or the driving mechanism such as cylinder, oil hydraulic cylinder, is undertaken controlling actuator's switch by ECU in manual or car.Actuator can drive friction wheel to be subjected to displacement, thus makes friction wheel and water pump drive take turns Contact Transmission or be separated with taking turns with water pump drive.
Motor is also provided with belt adjusting mechanism, and comprise the rotating turret 5 that can rotate under actuator drives, rotating turret is triangular in shape, is connected in the middle part of rotating turret with engine rotation.Rotating turret be provided with can with the Idle wheel 2 of belt contacts.The upper end of rotating turret is provided with the wheel carrier 3 be rotationally connected, and Idle wheel is arranged on the left end of wheel carrier, is provided with holddown spring 4 between the right-hand member of wheel carrier and rotating turret.Friction wheel is provided with friction wheel support 8, and friction wheel support is provided with directional post 9, and the lower end of rotating turret is provided with the guide groove 501 matched with directional post.The direction of displacement that friction wheel and water pump drive are taken turns overlaps with the radial direction that water pump drive is taken turns, friction wheel and water pump drive take turns between radial maximum displacement be 5mm.
In actual use, when motor just started need warming-up time, as shown in Figure 1, when friction wheel and water pump drive are taken turns and be separated by actuator, belt only drives friction wheel to rotate, and water pump drive wheel does not rotate, water pump does not operate, thus engine body temperature is raised rapidly; At the end of warming-up, as shown in Figure 2, when actuator's promotion friction wheel makes it to take turns with water pump drive and contacts, belt drive friction wheel makes and then drives water pump drive to be taken turns and rotates, and water pump can run well.In warming-up process, be separated because friction wheel is taken turns with water pump drive by actuator, belt is by further tensioning, and actuator makes rotating turret rotate simultaneously, and the Idle wheel on rotating turret is reduced for the tension force of belt.
