Abstract
The utility model discloses a reversing structure of a power-driven van, and can effectively solve the problems that uncontrollable reversing return and potential safety hazards in a reversing structure of an existing power-driven van. The reversing structure of the power-driven van comprises a reversing handle and a reversing shaft which is in shaft connection with the reversing handle, a turn angle potentiometer is installed on the bottom of the reversing shaft and is in electronic-control-signal connection with a reversing motor, and the reversing shaft penetrates through a reversing installation frame and is installed on the reversing installation frame through a bearing. The reversing structure of the power-driven van is characterized in that a first friction block, a spring and a second friction block are successively installed on the periphery of one side of the reversing shaft from top to bottom, wherein the one side of the reversing shaft is close to the reversing handle. The first friction block is installed on the reversing installation frame in a close-fitting mode, the second friction block is installed on the periphery of the reversing shaft in a close-fitting mode, the upper end of the spring is pressed tightly by the second friction block, and the lower end of the spring is limited by a limiting ring of the reversing shaft.
Description
Technical field
The utility model relates to the handling vehicle field, is specially a kind of steering structure of electrocar.
Background technology
The existing electronic car steering structure of removing comprises steering tiller and the steering shaft that mutually is coupling, see Fig. 1 and Fig. 2, wherein steering shaft 11 passes and turns to erecting frame 2, and by clutch shaft bearing 12, the second bearing 13 is installed on and turns to erecting frame 2, steering shaft 1 outside is equipped with torsion spring 14, torsion spring 14 can be given steering shaft 11 certain turning to torsion and can allow the steering tiller self-aligning, drive the steering shaft rotation by rotating steering tiller during steering operation, thereby drive the corner potential device that is installed on the steering shaft bottom and rotate the generation angular signal, the control steer motor was rotated after the steer motor controller received this angular signal, its shortcoming is: because torsion spring has the self-return function, in use as long as operating personal unclamps steering tiller, steering shaft just can drive steering tiller auto-steering return under the return effect of torsion spring, and the corner potential device also can produce angular signal and be rotated by steer motor controller control steer motor simultaneously, afterwards driving wheel flutter turns to, and tend in actual use exist the situation that does not need this kind auto-steering, and this kind auto-steering also may cause electrocar to be in danger out of control, brings hidden danger to safety in production.Among Fig. 2,15 is the clutch shaft bearing mount pad, and clutch shaft bearing 12 is installed on by clutch shaft bearing mount pad 15 and turns to erecting frame 2; 6 is bearing plate, and it plays the 13 axially movable effects of restriction the second bearing.
Summary of the invention
For the problems referred to above, the utility model provides a kind of steering structure of electrocar, and it can effectively overcome the problem that return is uncontrollable, have potential safety hazard that turns to of existing electrocar steering structure existence.
Its technical scheme is such, it comprises steering tiller and the steering shaft that mutually is coupling, described steering shaft bottom is equipped with the corner potential device, described corner potential device is connected with steer motor controller automatically controlled signal, described steering shaft passes and turns to erecting frame and be installed on the described erecting frame that turns to by bearing, it is characterized in that: described steering shaft is equipped with the first friction shoe from top to bottom successively near the periphery of described steering tiller one side, spring and the second friction shoe, described the first friction shoe close-fitting is installed on the described erecting frame that turns to, described the second friction shoe close-fitting is installed on described steering shaft periphery, and the upper end of described spring is compressed by described the second friction shoe, the lower end is spacing by the spacing ring of described steering shaft.
It is further characterized in that: described the first friction shoe is installed on the described erecting frame that turns to by bearing mounting base.
Compare with the steering structure of existing electrocar, the beneficial effects of the utility model are: it replaces torsion spring in the existing structure with spring, and spring by compress with the second friction shoe of steering shaft close-fitting, the second friction shoe top is by spacing with the first friction shoe that turns to the erecting frame close-fitting to install, it stops the automatic rotary of steering shaft under the effect that does not turn to external force by the friction force between the first friction shoe and the second friction shoe, thereby reliable and stable when guaranteeing vehicle parking effectively avoids potential safety hazard.
Description of drawings
Fig. 1 is the structural representation of existing electrocar;
Fig. 2 is the steering structure schematic diagram of existing electrocar;
Fig. 3 is the steering structure schematic diagram of the utility model electrocar.
The specific embodiment
See Fig. 3, the utility model comprises steering tiller 11 and the steering shaft 1 that mutually is coupling, steering shaft 1 bottom is equipped with corner potential device 8, corner potential device 8 is connected with steer motor controller (not expressing among the figure) automatically controlled signal, steering shaft 1 passes to turn to erecting frame 2 and be installed on by bearing 7 and turns to erecting frame 2, steering shaft 1 is equipped with the first friction shoe 3 from top to bottom successively near the periphery of steering tiller 11 1 sides, spring 5 and the second friction shoe 9, the first friction shoe 3 close-fittings are installed on and turn to erecting frame 2, the second friction shoe 9 close-fittings are installed on steering shaft 1 periphery, and the upper end of spring 5 is compressed by the second friction shoe 9, the lower end is spacing by the spacing ring 10 of steering shaft 1.The first friction shoe 3 is installed on by bearing mounting base 4 and turns to erecting frame 2.Among Fig. 3,6 is bearing plate.
Specifically describe working process of the present utility model below in conjunction with accompanying drawing: see Fig. 3, when carrying out steering operation when rotating steering tiller 11 with steering tiller 11 to pressing down, because steering tiller 11 is coupling with steering shaft 1, so that the second friction shoe 9 holddown springs 5, the corner potential device 8 of steering shaft 1 bottom produces angular signal and this signal is passed to the steer motor controller, turned to by steer motor controller control wheel flutter, namely finish conventional steering operation, operating personal unclamps steering tiller 11 when Parking, spring 5 upwards resilience and promote the second friction shoe 9 and steering shaft 1 upwards until the second friction shoe 9 contacts with the first friction shoe 3 holds out against, owing to being subject to the friction force effect between the first friction shoe 3 and the second friction shoe 9, steering shaft 1 can't carry out the certainly revolution of angle, thereby reliable and stable can guarantee vehicle parking the time, effectively avoid potential safety hazard.The first friction shoe 3 and the second friction shoe 9 can be made by wear-resistant plastic.
