Description
Technical field
The utility model relates to automotive brake systems design field, particularly relates to a kind of parking brake structure and automobile.
Background technology
Current most of car brake system adopts brake parking mechanism, and its principle is by finger-tight parking brake pull bar, and parking brake pull bar connects parking drag-line, and parking drag-line is connected with automobile rear brake, thus braking during standstill masterpiece is used for trailing wheel.The size of braking during standstill power is relevant with the deceleration and stopping performance of the lever ratio of the operating effort acted on parking brake pull bar, parking brake structure, the mechanical efficiency of parking structure and rear brake.Because the requirement of different vehicle braking forces is different, therefore need the parking brake structure of assembling different lever ratio, this just causes parking brake structure can not be general in each vehicle, adds the cost of parking brake mechanical development design and development checking.
Utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of parking brake structure and automobile, solves the problem of parking brake structure poor universality in prior art.
According to an aspect of the present utility model, provide a kind of parking brake structure, comprising:
Parking brake bearing, is fixed on body platform;
Parking brake pull bar, is rotatably connected with parking brake bearing; And
Parking drag-line, is fixed on parking brake pull bar;
Wherein, parking brake pull bar offers multiple installation gear, and the distance of the junction of each installation gear and parking brake pull bar and parking brake bearing is all unequal, parking drag-line can be fixed on a gear in multiple installation gear.
Alternatively, parking brake pull bar is connected with parking brake bearing by rotating shaft, and parking brake pull bar can rotate around the axis.
Alternatively, install gear for installing through hole, parking drag-line is hooked in be installed in through hole.
Alternatively, one end that parking brake pull bar is relative with parking drag-line is arranged with a sheath.
According to another aspect of the present utility model, additionally provide a kind of automobile and comprise parking brake structure as above.
The beneficial effect of embodiment of the present utility model is: a kind of parking brake structure and automobile, by offering multiple installation gear for fixing parking drag-line on parking brake pull bar, when parking drag-line is installed on different installation gears, the lever ratio of parking brake structure is different, therefore when needs adjustment braking during standstill power, only need adjust the installation gear of parking drag-line, this structure is applicable to the vehicle that different braking during standstill power requires, can save the development and Design of parking brake structure and the cost of exploitation checking to a certain extent.
Accompanying drawing explanation
Fig. 1 represents the structural representation of parking brake structure of the present utility model.
Wherein in figure: 1, parking brake bearing, 2, parking brake pull bar, 3, parking drag-line, 4, rotating shaft;
21, gear is installed, 22, sheath.
Detailed description of the invention
Below with reference to accompanying drawings exemplary embodiment of the present utility model is described in more detail.Although show exemplary embodiment of the present utility model in accompanying drawing, however should be appreciated that can realize the utility model in a variety of manners and not should limit by the embodiment set forth here.On the contrary, provide these embodiments to be in order to more thoroughly the utility model can be understood, and complete for scope of the present utility model can be conveyed to those skilled in the art.
Embodiment
The effect of emergency brake system makes the resident brake system as you were of the automobile of stagnation of movement, and current most of car emergency brake system adopts hand-braking structure.Can vehicle parking depend on the parking power of rear brake and the size of the sliding force of vehicle on ramp in certain gradient, the sliding force of vehicle on ramp is relevant with vehicle weight to the angle in ramp, angle is larger, vehicle is heavier, the sliding force produced is larger, and therefore required parking power is also larger.And the size of parking power is relevant with the deceleration and stopping performance of the lever ratio of the operating effort acted on parking brake pull bar, parking brake structure, the mechanical efficiency of parking structure and rear brake, operating effort and lever ratio larger, mechanical efficiency and deceleration and stopping performance higher, the braking during standstill power of vehicle is larger.Due to varying in weight of different automobile types, the braking during standstill power thus needed is also different, therefore needs the parking brake structure of assembling different lever ratio, to adapt to the demand of braking during standstill power.As shown in Figure 1, embodiment of the present utility model provides a kind of parking brake structure, comprising: be fixedly installed on the parking brake bearing 1 on body bottom panel, the parking brake pull bar 2 be rotatably connected with this parking brake bearing 1, and is fixed on the parking drag-line 3 on parking brake pull bar 2.Wherein, parking brake pull bar 2 is provided with multiple installation gear 21, parking drag-line 3 can be fixedly installed on a gear in multiple installation gear 21, and wherein, it is all unequal apart from the distance of parking brake pull bar 2 and parking brake bearing 1 junction that each installs gear 21.When parking drag-line 3 is installed on different installation gears 21, the lever ratio of parking brake structure is different, therefore the braking during standstill power provided is different, this parking brake structure is applicable in the vehicle of different braking during standstill power requirement like this, can save development and Design cost and the exploitation checking cost of parking brake structure to a certain extent.
Alternatively, as shown in Figure 1, with the similar of parking brake structure in prior art, parking brake pull bar 2 is connected with parking brake bearing 1 by rotating shaft 4, and parking brake pull bar 2 can rotate around this rotating shaft 4.Chaufeur is by operation parking brake pull bar 2, and parking brake pull bar 24 rotates around the shaft, under the point action of parking brake bearing 1, operating effort is transferred to parking drag-line 3, and then makes parking drag-line 3 drive rear brake to realize the braking of trailing wheel.
Alternatively, as shown in Figure 1, the installation gear 21 on parking brake pull bar 2 is set to install the form of through hole, and of being hooked in multiple installation through hole installs on through hole parking drag-line 3, realizes being fixedly connected with of parking drag-line 3 and parking brake pull bar 2.It is worthy of note, the above parking drag-line 3 is hooked in connection mode on parking brake pull bar 2 and of the prior art to be fixedly connected with mode similar, therefore is not described in detail at this.
Alternatively, as shown in Figure 1, for the ease of driver's operation parking brake pull bar 2, one end that this parking brake pull bar 2 is relative with parking drag-line 3 is arranged with a sheath 22, this sheath makes driver's operation parking brake pull bar 2 more comfortable, and can increase the friction coefficient of parking brake pull bar 2, is convenient to driver's operation.
According to another aspect of the present embodiment, additionally provide a kind of automobile, comprise parking brake structure as above.
Above-described is preferred implementation of the present utility model; should be understood that the ordinary person for the art; can also make some improvements and modifications not departing under principle prerequisite described in the utility model, these improvements and modifications are also in protection domain of the present utility model.
