Description
Technical field
The invention belongs to light vehicle field, particularly relate to a kind of two-wheel wheel rack device.
Background technology
The midfoot support of axletree is lived by the two-wheel support of prior art compact car generally by supporting seat the earliest, then exists
The two ends installing wheel of axletree, to form dual wheels, when using this dual wheels, it is generally required to fix support seat, two
Axially also being fixed of wheel, during turning, wheel cannot cause floating of one of them wheel along with the inclination of vehicle frame, lead
Cause turn time can disequilibrium, turn to extremely difficult.
The problem turning to difficulty for solving two-wheel, people use the wheel connecting two sidecar wheels at a wheel shaft sidewards in recent years
One differential mechanism is installed in the middle of axle and changes two wheels of vehicle speed difference of rotating speed when turning, reach to solve two-wheel and turn
Time can disequilibrium, turn to the problem of difficulty, but this kind installs the method for differential mechanism at Ackermann steer angle on the wheel shaft of wheel
Wheel still also cannot can cause floating of one of them wheel along with the inclination of vehicle frame, understands disequilibrium, turns when causing turning
To extremely difficult.
Prior art Patent number be the two-wheel wheel fork of a 201620488812X band vibration damping be that the present inventor researches and develops improvement
A kind of two-wheel wheel fork, although this two-wheel wheel fork is provided with crane span structure between two wheel forks, and crane span structure the right and left arranges wheel fork even
Connect and be cased with the prismatic axle of shock-absorbing spring in the installing hole of arm on prismatic guide pin bushing and the right and left wheel fork and be flexibly connected, therefore work as vehicle
When in the middle of exercising, road is uneven, prismatic axle can do in the prismatic axle movable span of prismatic guide pin bushing along with the vibration of spring
Lower rectilinear movement, owing to the structure of prismatic axle designs, changes piece wheel shaft of tradition and connects the design of two sidecar wheels sidewards, and crane span structure is taken turns
The design of fork can not only play the enforcement of the alignment and balance in two-wheeled direction, left and right, and can reach again the purpose of independent shock-absorbing.
But when two-wheel wheel fork is turned, spring sometimes there will be the compression problem such as insensitive, and during turning, wheel still cannot tilt, and also can
Cause floating of one of them wheel, just do not reach balance, unstable, still cannot solve to turn to difficult problem.
Summary of the invention
It is an object of the invention to for shortcoming of the prior art, and provide design to be possible to prevent Ackermann steer angle one wheel
Floating of son, turns to difficulty solving the sulky vehicle of existing two-wheel support, thus realizes when turning that dual wheels can be along with car
The inclination of body and tilt, reach balance and stability, improve a kind of two-wheel wheel rack device of turn performance.
The technical scheme is that a kind of two-wheel wheel rack device, mainly by two axle blocks 12, be fixedly mounted on wheel shaft
The wheel shaft 13 being used for installing wheel on seat 12 and the wheel carrier composition being connected on two axle blocks 12；It is characterized in that: described
Wheel carrier mainly by controlling fork 2, front and back two axle block bracing frames 7 and the wheel being arranged between two axle block bracing frames
Axle bed control cage 4 forms；Structure and installation between it are connected as: be provided with axis hole six at the two ends of two axle block bracing frames 7
20, corresponding also is provided with axis hole 8 22 on two axle blocks, and two jointed shafts 4 11 are respectively by axle block bracing frame two
Two axle blocks 12 are respectively articulated with and are arranged on two axle block bracing frames 7 by the axis hole 8 22 on the axis hole 6 20 of end and axle block
Two ends on, and axle block 12 is to swing back and forth with jointed shaft 4 11 for axle center；At two described axle blocks 12
Top is designed with two engaging lugs 9 of band axis hole 7 21, and the corresponding two ends in axle block control cage 4 also are provided with axis hole five
19, two jointed shafts 3 10 are respectively by axis hole 7 21 and the axle block control cage two ends of two engaging lugs in two axle block top
Axis hole 5 19 two ends of axle block control cage 4 are respectively hinged on two engaging lugs 9 of two axle blocks；Control fork 2 solid
Determine connection to be arranged on below vehicle steering shaft 1；It is provided with an axis hole 1 in the centre controlling fork 2, is provided with controlling fork 2 bottoms
One axis hole 2 16, is controlling to be additionally provided with on fork 2 loose slot 3 of horizontal axle block control cage 4 activity of confession；With axis hole one
An axis hole 3 17 is also designed in the 15 corresponding centres in axle block control cage 4, and the axle block control cage 4 being transversely mounted is by cutting with scissors
Spindle 1 is hinged on, by controlling the axis hole 1 on fork 2 and the axis hole 3 17 in axle block control cage 4, the activity controlling to pitch 2
On groove 3；Corresponding with axis hole 2 16 is also respectively equipped with an axis hole 4 18 front and back in the middle of two axle block bracing frames 7, hinge
Spindle 26 is by the axis hole 4 18 on two axle block bracing frames 7 front and back and controls the axis hole 2 16 of fork 2 bottoms by control fork 2
Bottom is movably articulated on two axle block bracing frames 7 of before and after；And control fork 2 is can left and right pendulum with jointed shaft 26 for axle center
Dynamic.
The advantage of a kind of two-wheel wheel rack device of the present invention is: due to the described wheel being connected on two axle blocks 12
Frame is mainly by controlling fork 2, front and back two axle block bracing frames 7 and the axle block being arranged between two axle block bracing frames
Control cage 4 forms, and is laterally through and controls the axis hole that the axle block control cage 4 of fork 2 loose slots 3 is pitched by control by jointed shaft 1
1 and axle block control cage 4 on axis hole 3 17 be hinged on control fork, jointed shaft 26 is supported by two axle blocks front and back
Control fork 2 bottoms are movably articulated in two axle blocks of before and after and prop up by axis hole 4 18 and the axis hole 2 16 of control fork 2 bottoms on frame 7
On support 7, and control fork 2 is can to swing with jointed shaft 26 for axle center, and axle block control cage 4 just can be along with control
Swinging front and back between the axle block bracing frame 7 of two of fork 2 swings, and controls the right and left axle block 12
Swinging, jointed shaft 4 11 passes through the axis hole 6 20 at axle block bracing frame two ends and the axis hole 8 22 of axle block respectively by axle block 12
Be hingedly mounted on the two ends of two axle block bracing frames 7, and axle block 12 be with jointed shaft 4 11 for axle center back and forth left and right
Swinging, the two ends of axle block control cage 4 are hinged on two engaging lugs 9 of two axle blocks by jointed shaft 3 10 the most respectively,
Therefore, when vehicle is turned to the left or to the right in enforcement, the center of gravity of people will tilt along with inclination of vehicle, below steering spindle
Control fork 2 will the driven wheel axle bed control cage of swing to the left or to the right 4 with jointed shaft 26 as axle center swing to the left or to the right,
Axle block control cage 4 swings to the left or to the right and drives two axle blocks 12 of the right and left to swing to the left or to the right, thus carries
Inclination that dynamic left and right two-wheel is turned to the left or to the right along with vehicle and tilt.When just can reach to prevent from turning, a wheel does not lands
Float thus solve two-wheel in prior art and turn to difficult problem, reach to improve turn performance, promote car body to turn to smoothly, turn
Curved balance and stability purpose.The position of centre of gravity that can make vehicle tilts to the direction turned, it is achieved the raising of turn performance makes occupant
It is difficult to experience centrifugal force.
