Abstract
The utility model relates to a crawler type multi-road condition automatic deformation wheel, which comprises a wheel blade, a half axle, a cam axle sleeve, a positioning spring, a vibration damping spring, a sliding axle, a driving disc, a half axle sleeve pipe, a hydraulic oil cylinder and a rolling axle. The hydraulic oil cylinder is utilized to drive the cam axle sleeve to slide horizontally on the half axle sleeve pipe, when the hydraulic oil cylinder draws the cam axle sleeve leftwards, the rolling wheel at the end part of the rolling axle is pressed at the different positions on the cam axle sleeve to cause that the outer outline of the deformation wheel is changed, thereby causing that vehicles not only can travel on the good road surface, but also can pass on the loose and soft road surface like sand road surface, snow road surface and miriness road surface. The utility model can effectively improve the off-road performance and the traffic capacity of the vehicles, and can reach the interchange with the walking mechanism the prior vehicle.
Description
Technical field
The utility model discloses a kind of automobile-used deformation wheel, refering in particular to is crawler type automatic deformation wheels for multiple highway conditions.
Background technology
In recent years, the development of automotive field has obtained great advance, and China also becomes the world the fourth-largest car production state.Common automobile traveling mechanism has two kinds: general round wheel and Athey wheel.Most wheels have adopted air-inflation tyre to contact with ground, and this also is our modal wheel form, and the automobile that this wheel is installed is mainly at highway with travel on the ground preferably.The impact that air-inflation tyre brings in the time of can absorbing running car well is fit to run at high speed.But because tire and ground-surface area of contact are smaller, make automobile under the situation in bad order of road surface,, occur easily sinking and skidding that crossing ability reduces greatly, even can't walk at all such as when sand ground, snowfield and mire travel.On the contrary, Athey wheel but has great ground contact area, also P Passable under the very poor situation of pavement conditions.Yet Athey wheel is bulky, complex structure, and special walking manner has determined it can not have as the speed of justifying wheel, add the destructive effect of metal track road pavement, some highway even limited entering of caterpillar-type vehicle is installed, these reasons make that the range of use of Athey wheel is very limited.
The utility model content
The purpose of this utility model is to overcome the deficiency of prior art, and provide a kind of simple in structure, easy to use, can adapt to the crawler type automatic deformation wheels for multiple highway conditions that change to realize running at high speed in the road surface, low speed passes through.
The utility model is to adopt following proposal to realize: it has a drive plate, one side of described drive plate is connected with semiaxis in being sleeved on axle tube by seal cover cap, the center that is equipped with opposite side is equipped with the seal cover cap of axle tube, outside described axle tube, be arranged with one group of hydraulic ram at least, one end of the cam sleeve that the piston of described hydraulic ram is outer with being sleeved on axle tube is connected, described drive plate upper edge radial equipartition has axis hole, in described axis hole, slide-bar is housed, one end of described slide-bar is hinged with the wheel sheet, the other end is hinged in the groove of roller shaft one end, the other end of described roller shaft is equipped with roller and contacts with cam sleeve, the wheel on the described adjacent slide-bar
