Description
Technical field
The utility model relates to a kind of vehicle parking device, relates in particular to a kind of vehicle parking brake control device.
Background technology
In the existing vehicle parking brake control device; Mainly comprise fixed support, and the parking brake that is rotatedly connected of fixed support draw handle, Parking backguy, be connected Parking backguy and parking brake draw between draught line; Parking brake draws realizes Parking spur the Parking backguy through the traction to draught line; As in the parking brake structure of Honda Accord car, it draws on the handle at parking brake and is provided with guide groove, draws in the process at the pulling parking brake; Draught line is tangent with guide groove all the time; And parking brake draw with fixed support between the different and time changing of the distance of the rotating shaft that is rotationally connected an and draught line angle of drawing along with parking brake, thereby reach the purpose of change lever ratio, and the power of draught line is delivered in the Parking backguy through a three-legged structure.Three-legged structure has three hinge-points, and one of them hinge-point and draught line are hinged, and second hinge-point and parking brake stay bearing plate are hinged; The 3rd hinge-point and Parking backguy are hinged; In this structure,, reduced transmission efficiency because guide groove can increase friction; And in particular moment, the bottom three-legged structure does not have the effect that increases lever ratio.
Summary of the invention
Be to solve the deficiency that exists in the prior art, the utility model provides a kind of and increased the parking brake lever ratio, with transmission efficiency that improves the parking brake structural capacity and then the vehicle parking brake control device that reduces the parking brake operating effort.
For realizing above-mentioned purpose; The vehicle parking brake control device of the utility model; Comprise fixed support, and the parking brake that is rotatedly connected of fixed support draw handle, Parking backguy, be connected Parking backguy and parking brake draw between draught line, described parking brake draws realizes Parking spur the Parking backguy through the traction to draught line, on fixed support, is provided with guiding mechanism; Described draught line rolls with guiding mechanism and cooperates; Through this setting of rolling and cooperating, actv. reduces the friction force between draught line and the guiding mechanism, and the brake operation force transmission efficiency of whole operating control is improved.
As qualification to the utility model; Described draught line is made up of first draught line and second draught line; Guiding mechanism is made up of first track adjusting wheel and second track adjusting wheel that rotation is arranged on the fixed support; Described first draught line is connected in parking brake and draws between the handle and second track adjusting wheel, and second draught line is connected between the Parking backguy and second track adjusting wheel.
As the improvement to the utility model, described second track adjusting wheel is a variable-diameter structure, and second track adjusting wheel is set to variable-diameter structure, can improve the transmission ratio of second track adjusting wheel to power, further strengthens the transmission efficiency of total.
As the qualification to aforesaid way, described second track adjusting wheel is made up of the big grooved wheel and the small grooved wheel of concentric setting, and the connection of first draught line is arranged in the race of big grooved wheel, and the connection of second draught line is arranged in the race of small grooved wheel.
As improvement to the utility model, on fixed support, be provided with the guide groove that the trend to second draught line leads, through setting up guide groove, the trend of second draught line is fixed, so that second draught line is more stable to the pulling of Parking backguy.
In sum, adopt technique scheme, can effectively strengthen the transmission efficiency of whole operating control to the Parking operating effort, and then reduce the parking brake operating effort, its integral structure is simple.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further to specify:
Fig. 1 is the integral structure scheme drawing of the utility model.
Among the figure: 1, fixed support; 2, parking brake draws handle; 3, Parking backguy; 41, first draught line; 42, second draught line; 51, first track adjusting wheel; 52, second track adjusting wheel; 521, big grooved wheel; 522, small grooved wheel; 6, guide groove; 7, rotating shaft.
The specific embodiment
The vehicle parking brake control device of the utility model is the improvement of on the existing design basis, making; Its structure identical with existing structure comprises fixed support 1, and the parking brake that is rotatedly connected through rotating shaft 7 of fixed support 1 draws 2, Parking backguy 3, be connected Parking backguy 3 and parking brake and draw the draught line between 2; Parking brake draws and spurs Parking backguy 3 realization Parkings to 2 through the traction to draught line; The improvements that the relative existing structure of the utility model is made are on fixed support 1, to be provided with guiding mechanism, and draught line rolls with guiding mechanism and cooperates.
Based on above-mentioned unit design thought; In the present embodiment; By shown in Figure 1, draught line is made up of first draught line 41 and second draught line 42, and guiding mechanism is made up of first track adjusting wheel 51 and second track adjusting wheel 52 that rotation is arranged on the fixed support 1; First draught line 41 is connected in parking brake and draws between 2 and second track adjusting wheel 52, the tangent setting of race of itself and first track adjusting wheel 51; Second draught line 42 is connected between the Parking backguy 3 and second track adjusting wheel 52.Wherein, second track adjusting wheel 52 is a variable-diameter structure, is made up of the big grooved wheel 521 and the small grooved wheel 522 of concentric setting, and 41 connections of first draught line are arranged in the race of big grooved wheel 521, and 42 connections of second draught line are arranged in the race of small grooved wheel 522.On fixed support 1, be provided with the guide groove 6 that the trend to second draught line 42 leads.
