Abstract
The utility model provides a vehicle is with keeping the liftable chassis that the directive wheel support frame is vertical, the chassis has drive wheel and directive wheel, and wherein the directive wheel is installed on the directive wheel support frame that scalable adjustment height and one end articulated on the chassis. The utility model discloses can portably adjust vehicle ground clearance, make things convenient for the use in the different scenes of using.
Description
Technical Field
The utility model relates to engineering, gardens and agricultural machine and the relevant field of instrument, a vehicle that can conveniently adjust ground clearance is with keeping the vertical liftable chassis of supporting leg has specifically designed.
Background
In fields such as agricultural and afforestation machinery, the ground clearance adjustment of hand propelled operation machinery is mostly locking again after the support frame adjustment terrain clearance of manual dismantlement walking wheel, complex operation, and it is consuming time many. How to make it easier and at the same time more economical to manufacture, adjusting the vehicle ground clearance has been a real problem that is urgently needed to be solved. In a specific application scenario, such as an offset hand-push mower, since the handle side is already turned to one side of the outer side of the mower body during operation, it is not convenient to tilt the other end of the mower in a manner of driving and pressing the handle so as to detach and adjust the height of the operation supporting wheel. Similarly, if a simpler method were available to adjust the ground clearance, the labor intensity and overall operating time costs would be significantly reduced.
Disclosure of Invention
The utility model provides a vehicle is with keeping the liftable chassis that the directive wheel support frame is vertical, the chassis has drive wheel and directive wheel, and wherein the directive wheel is installed on the directive wheel support frame that scalable height-adjusting and one end hinged on the chassis. The utility model discloses can portably adjust vehicle ground clearance, make things convenient for the use in the different scenes of using.
The utility model provides a pair of vertical liftable chassis of directive wheel support frame is kept with to vehicle, including chassis, drive wheel, directive wheel support frame and directive wheel. The structure is as follows:
one side of the chassis is provided with a driving wheel.
The other side of the chassis is provided with a limiting plate with an arc-shaped groove.
The steering wheel support frame is a pair of telescopic supports, the fixed end of the telescopic supports is hinged to one side of the limiting plate of the chassis support, and the telescopic ends are provided with positioning blocks which are inserted into the arc-shaped grooves of the limiting plate.
The telescopic end is simultaneously provided with a steering wheel.
Further, the fixed end and the telescopic end of the steering wheel support frame are nested and installed together along the telescopic direction, and a linear telescopic adjusting mechanism is arranged.
Further, when the plane of the chassis frame is in a horizontal state, the positioning block at the telescopic end of the steering wheel support frame is positioned in the middle of the total span of the arc-shaped groove of the limiting plate.
Furthermore, the arc-shaped groove of the limiting plate is in the form of an involute arc taking the axle center of a hinge shaft at the fixed end of the steering wheel support frame as the center of a circle.

Fig. 2 is one of the perspective views of the present invention.
Fig. 3 is a back perspective view of the limiting plate arc-shaped groove track of the present invention.
Detailed Description
The essential features and advantages of the invention will be further explained below with reference to examples, but the invention is not limited to the embodiments listed.
Referring to fig. 1, a driving wheel shaft 2 is installed on the front side of a chassis 1, and driving wheels 3 are installed on both ends of the driving wheel shaft 2.
The bottom of the rear side of the chassis 1 is provided with a limiting plate 5 with an arc-shaped groove 4.
The fixed end 6 of the steering wheel support frame is hinged to the top of the rear side of the chassis 1 through a hinge 7.
The top of the telescopic end 8 of the steering wheel support frame is connected to the bottom of the fixed end 6 of the steering wheel support frame through two pairs of telescopic sleeves 9.
The middle part of the telescopic end 8 of the steering wheel support frame is provided with a hinge hole and is inserted into the arc-shaped groove 4 of the limiting plate 5 through a bolt 10.
A pair of steering wheels 11 are arranged at the bottom of the telescopic end 8 of the steering wheel support frame.
A steering link 18 is mounted between the pair of steering wheel brackets 17.
In the state shown in fig. 1, the frame plane of the chassis 1 is horizontal, and at the moment, the positioning block bolt 10 of the telescopic end 8 of the steering wheel support frame is positioned in the middle of the total span of the arc-shaped groove 4 of the limiting plate.
Referring to fig. 2, a screw rod 12 and a corresponding nut 13 are respectively arranged on the fixed end 6 and the telescopic end 8 of the steering wheel support frame for adjusting the extension of the fixed end 6 and the telescopic end 8 of the steering wheel support frame, and a rotating handle 14 is arranged at the other end of the screw rod 12.
Referring to fig. 1 and 3, the arc-shaped groove 4 of the limiting plate 5 is an involute arc with a center line 15, which is centered on the hinge point of the fixed end of the steering wheel support frame, i.e., the axis of the hinge shaft 16 of the hinge 7.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
