Fig. 1 is the parking system schematic diagram of the embodiment of the present invention；
Fig. 2 is the brake-power compensator schematic diagram of the parking system of the embodiment of the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in embodiment of the present invention is clearly and completely described.
Parking system is that the wheel that its role is to maintain vehicle makes it to rotate for parked vehicle being maintained at resting state, making its irremovable device.
Fig. 1 is the structural representation of a kind of drag-line parking system of the embodiment of the present invention.Described parking system includes in parking controller the 2, first drag-line 1, second drag-line 3 and brake-power compensator 4(figure and do not represent).Described first drag-line 1 and the second drag-line 3 are respectively used to couple together parking bar (not shown) with being arranged on brake (not shown) on wheel.Described brake-power compensator 4 is arranged in described parking controller 2.
Described first drag-line 1 and one end of the second drag-line 3 are connected with corresponding brakeage lever (not shown), and the other end is connected with brake-power compensator 4, and brake-power compensator 4 is connected with parking controller 2.The effect of brake-power compensator 4 is that the load being applied on the first drag-line 1 of wheel and the second drag-line 3 realizes equal.The first drag-line 1 and the second drag-line 3 in parking system act on the brake, brake and wheel effect, make wheel to rotate.
Fig. 2 is the structural representation of the brake-power compensator 4 of a kind of parking system of the embodiment of the present invention.As it can be seen, described brake-power compensator 4 includes a scroll bar 401, described scroll bar 401 is connected with driving motor 5.Described brake-power compensator 4 also includes a turbine 402, and described scroll bar 401 engages with turbine 402, and described scroll bar 401 is driving being rotated by of motor, meanwhile, drives turbine 402 to rotate.Described turbine 402 is fixed axle 403 by driving gear and is arranged on parking controller housing 21, when turbine 402 rotates, drives described driving gear to fix axle 403 and rotates.Fix, by driving gear, the driving gear 404 that axle 403 is arranged on parking controller housing 21, when driving gear fixes axle 403 rotation, described driving gear 404 can be driven to rotate.Described driving gear 404 engages with driven gear 405, when driving gear 404 rotates, drives described driven gear 405 to rotate.Described driven gear 405 is fixed axle 407 by driven gear and is connected with described parking controller housing 21 and driven gear wire spool 408 respectively.Described driven gear 405, under the driving of driving gear 404, drives described driven gear wire spool 408 to rotate.Described driven gear wire spool 408, for connecting the first drag-line 1 and the second drag-line 3 of described parking system, and drives described first drag-line and described second drag-line work.
In parking system work process, described parking controller 2 can rotate by driving driving gear to fix axle 403, driving gear fix axle 403 and drive driving gear 404 to rotate.Driving gear 404 engages with driven gear 405, drives driven gear 405 to rotate, and thus drives driven gear wire spool 408 to rotate.When driven gear wire spool 408 rotates, the first drag-line 1 and the second drag-line 3 can be pulled simultaneously, and because the first drag-line 1 and the second drag-line 3 are both connected to driven gear wire spool 408, both stress are equal, ensure consistent effect on the brake, and then acted on and wheel by brake, make wheel to rotate, it is achieved the purpose of parking.By turbine and worm transmission, the parking power of parking system can realize mechanical self-latching.
Above-mentioned turbine 402 can be complete circular gear, it is also possible to be sector gear as shown in Figure 2.It is said that in general, when worm gear is under the driving of worm screw, when rotational angle is less than 360 °, uses sector gear can reduce the space shared by turbine, the most more save material.
Above-mentioned driven gear 405 can be complete circular gear, it is also possible to be sector gear as shown in Figure 2.When the rotational angle that driven gear wire spool 408 drives described first drag-line 1 and the work of the second drag-line 3 is not reaching to 360 °, use sector gear can reduce the space shared by driven gear 405.
As shown in Figure 2, swing arm 406 can also be coupled by a gear and described driving gear be fixed axle 403 and driven gear is fixed axle 407 and coupled together, increase driven gear wire spool 408 further and drive the concordance of stress in described first drag-line 1 and the work of the second drag-line 3.
During it addition, described first drag-line 1 and the second drag-line 3 are wrapped on described driven gear wire spool 408, it is also possible to strengthen driven gear wire spool 408 and drive the concordance of stress in described first drag-line 1 and the work of the second drag-line 3.
In another one embodiment, can from different directions the first drag-line 1 and the second drag-line 3 be wrapped on described driven gear wire spool 408.As in figure 2 it is shown, be to be wound around described first drag-line 1 and the second drag-line 3 in opposite directions.When described driven gear wire spool 408 rotates, the first drag-line 1 and the second drag-line 3 move the most in different directions, and finally make different wheels stop operating.
In another embodiment, in order to ensure first drag-line 1 and the direction of motion of the second drag-line 3, some directive wheels can be set at brake-power compensator.As in figure 2 it is shown, the first drag-line 1 guides through the first directive wheel 410, the second drag-line 3 guides through the second directive wheel 409.Guarantee that the first drag-line 1 and the second drag-line 3 move according to specific direction respectively, and then preferably reach the effect of anticipation, it is ensured that wheel cannot rotate.In real process, the quantity of directive wheel can as shown in Figure 2 two, it is also possible to be more.
The embodiment of the present invention additionally provides a kind of automobile, the parking system described in dynamical system and claim 7, and described dynamical system can be motor, it is also possible to be gasoline engine, the power needed for providing for automobile.
The above is the preferred implementation of the embodiment of the present invention; it should be pointed out that, for those skilled in the art, on the premise of without departing from embodiment of the present invention principle; can also make some improvements and modifications, these improvements and modifications are also considered as protection scope of the present invention.
