Description
Technical field
The utility model is related to vehicle manufacture field, in particular to a kind of pedal assembly for vehicle and has
This is used for the vehicle of the pedal assembly of vehicle.
Background technology
In correlation technique, the brake pedal used on automobile can be divided into two kinds：Truck dead lever is than pedal and variable lever ratio
Pedal.Truck dead lever is generally suspension type structure than pedal, i.e., using simple lever principle, one end connection rotating shaft of pedal arm and
Used as fulcrum, the other end of pedal arm connects input of the pedal tread as power, and the one end on pedal arm near rotating shaft is connected with
Bearing pin, bearing pin is the output end of power.The pedal structure is simple, cheap；But the lever ratio of brake pedal is immutable, there is provided
Force characteristic cannot realize the desirability of brakes.
Four-bar linkage structure being used variable lever ratio pedal, wherein a rocking bar is used as pedal arm, a rocking bar is made in addition more
It is the output arm of force, its lever ratio gradually increases from small.Early stage i.e. in pedal travel has less lever ratio, can quickly disappear
Except idle stroke sets up pressure；There is larger lever ratio in the later stage of pedal travel so that driver can use less pedal
Power produces larger hydraulic pressure.The brake pedal input-output characteristic of quadric chain is more preferable, but due to complex structure, manufacture
It is relatively costly.

Chute 5, the first jointed shaft 6, the second jointed shaft 7, pedal support 8.
Specific embodiment
Embodiment of the present utility model is described below in detail, the example of the embodiment is shown in the drawings.Below by
The embodiment being described with reference to the drawings is exemplary, it is intended to for explaining the utility model, and it is not intended that new to this practicality
The limitation of type.
In the description of this specification, reference term " one embodiment ", " some embodiments ", " example ", " specifically show
The description of example " or " some examples " etc. means to combine specific features, structure, material or spy that the embodiment or example are described
Point is contained at least one embodiment of the present utility model or example.In this manual, to the schematic table of above-mentioned term
State and be necessarily directed to identical embodiment or example.And, the specific features of description, structure, material or feature can be with
Combined in an appropriate manner in any one or more embodiments or example.Additionally, in the case of not conflicting, this area
Technical staff the feature of the different embodiments or example described in this specification and different embodiment or example can be entered
Row is combined and combined.
The utility model is described with reference to refer to the attached drawing and specific embodiment.
The pedal assembly 100 for vehicle of the utility model embodiment is described with reference to Fig. 1 first.
As shown in figure 1, including pedal support 8, pedal arm 2, pedal 1, connecting rod 3 and defeated for the pedal assembly 100 of vehicle
Go out portion 4.One end of pedal arm 2 is hinged with pedal support 8, and pedal support 8 is fixedly connected with the vehicle body of vehicle, and the one of pedal arm 2
End is first axle with the hinge axes of pedal support 8.Pedal 1 is located at the other end of pedal arm 2.One end of connecting rod 3 and pedal
The middle part of arm 2 is hinged, and one end of connecting rod 3 can be second axis with the hinge axes at the middle part of pedal arm 2.Output section 4 and company
Bar 3 is hinged and connected and output section 4 is removable along straight line.
Specifically, as shown in figure 1, the first jointed shaft 6 and the second jointed shaft can be included for the pedal assembly 100 of vehicle
7, one end and the pedal support 8 of pedal arm 2 are hinged by the first jointed shaft 6, i.e. the central axis and first axle of the first jointed shaft 6
Line overlaps, one end of connecting rod 3 being hinged by the second jointed shaft 7, the i.e. central shaft of the second jointed shaft 7 with the middle part of pedal arm 2
Line overlaps with second axis.One end of pedal arm 2 and being hinged for pedal support 8 can fix hinge, one end of connecting rod 3 and pedal
Being hinged for the middle part of arm 2 can be middle hinge.
When driver is to 1 input power of pedal, pedal arm 2 around first axle rotate, the connecting rod 3 being hinged with pedal arm 2 around
First axle is rotated and rotated around second axis, and the motion of connecting rod 3 drives output section 4 to be produced along straight line (L4 directions in Fig. 1)
Raw displacement, in pedal arm 2 in first axle rotation process, the angle (alpha+beta) between pedal arm 2 and connecting rod 3 constantly becomes big.
As shown in figure 1, the power and the arm of force of the input of pedal 1 are respectively F2 and L2, the power and the arm of force of the output of connecting rod 3 are respectively F1
And L1.The distance between first axle and second axis are R, and the power of output to output section 5 is F3, between pedal arm 2 and connecting rod 3
Angle (alpha+beta).
According to lever principle：F1=(F2L2)/L1 (1)
Had according to trigonometric function：L1=Rsin (alpha+beta) (2)
F3=F1sin α (3)
Arrange and can obtain according to formula (1), (2), (3)：
F3=((F2L2))/L1sin α=F2L2sin α/(Rsin (alpha+beta)) (4)
I=F3/F2=L2sin α/(Rsin (alpha+beta)) (5)
It is understood that L1 changes as the angle (alpha+beta) between pedal arm 2 and connecting rod 3 changes, and because alpha+beta
∈ (0,180 °), it can thus be appreciated that：When alpha+beta ∈ (0,90 °), lever ratio i is smaller；When alpha+beta ∈ (90 °, 180 °), sin α increase
Greatly, sin (alpha+beta) reduces, sin α/sin (alpha+beta) increases, therefore lever ratio i increases.
The pedal assembly 100 for being consequently for vehicle realizes the change of lever ratio in the course of the work.
According to the pedal assembly 100 for vehicle of the utility model embodiment, by setting pedal arm 2, pedal 1, connecting
It is hinged and connected between bar 3 and output section 4, the pedal assembly 100 for being used in vehicle constitutes slider-crank mechanism, by power input
The circular motion of pedal 1 is converted into the linear motion of the output section 4 of power output end, makes thick stick during driver's pushes pedals 1
Bar gradually increases than i, i.e., in the early stage of pedal travel, there is provided less lever ratio i, can effectively shorten idle stroke, in pedal row
In the later stage of journey, there is provided larger lever ratio i, the input power F2 at pedal 1 can be reduced, obtain larger brake force, effectively carried
Rise the sensation of driver's pushes pedals 1.Simultaneously as output section 4 moves along a straight line, the vehicle part being connected with output section 4
(such as vacuum booster, various pump classes) can be kept along axial-movement, without reusing ball head structure, make the overall design of vehicle more
