Abstract
The utility model relates to a ground claw braking device on an ice-snow road surface. The ground claw braking device on the ice-snow road surface structurally comprises a cantilever hinged to an automotive rear axle, an oil cylinder, a tension spring, a transversely arranged bent frame, and a plurality of steel nails, wherein the oil cylinder is arranged on the automotive rear axle and used for driving a rotation arm to move, the tension spring is connected between an automotive chassis and the cantilever and used for pulling the rotation arm, the bent frame is connected at the rear end of the rotation arm, and the plurality of steel nails are connected to the bent frame. The use of the ground claw braking device on the ice-snow road surface enables an automobile to stop and run safely in the travelling process on the ice-snow road surface, reduces the occurrence of traffic accidents, and protects the safety of people and property.
Description
Technical field
The utility model relates to a kind of auxiliary automobile braking device, specifically a kind of ice-snow field ground pawl brake gear.
Background technology
Accumulated snow, freezing highway up train are being arranged, the phenomenon of slipping of brake occurring through regular meeting, the traffic accident of the traffic accident that causes thus during than the driving of normal highway section will exceed doubly a lot.And adopt anti-slipping chain to twine the non-skid feature of tire, though can improve the antiskid capability of ice-snow field up train, when vehicle drove on the nothing snow highway section, the anti-slipping chain on the tire will cause certain infringement to the road surface of highway.So, the technical scheme that does not also have a kind of effective solution snowfield to brake at present.
The utility model content
The purpose of this utility model just provides a kind of ice-snow field ground pawl brake gear, to solve the problem that on ice-snow field traveling automobile is difficult for checking car, reduces the generation of traffic accident.
The utility model is achieved in that a kind of ice-snow field ground pawl brake gear, include: be hinged on the cantilever on the automobile axle, be arranged on the automobile axle, be used for promoting the oil cylinder of described spiral arm action, be connected between car chassis and the described cantilever, be used for the extension spring of the described spiral arm of pulling, be connected the horizontal framed bent of described spiral arm rear end, and be connected the some steel nails on the described framed bent.
The rear end of described framed bent and described cantilever is fixed together.
Peg graft by axle sleeve and spindle nose and be connected in the rear end of described framed bent and described cantilever.
The utility model is by being erected at the front end face of the piston rod promotion spiral arm in the oil cylinder on the back axle, the spiral arm rear end is sunk, the framed bent and the steel nail that are connected the spiral arm rear end are pressed towards the road surface, thereby make steel nail take off the accumulated snow on the road surface or freeze layer, reach the purpose of stable brake.When piston rod was return in the oil cylinder, spiral arm can be made the steel nail on the framed bent break away from the road surface by the extension spring pull-up, and automobile can normally travel.And when vehicle drives on the normal road surface, but because the automobile normal braking, need not this auxiliary brake, thereby can not cause damage to highway pavement.
Use of the present utility model can make vehicle realize ice-snow field driving process safe parking and safe driving, has reduced the generation of traffic accident, has protected the safety of personnel and property.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of a kind of implementation of framed bent.
Among the figure: 1, semiaxis, 2, back axle, 3, oil cylinder, 4, cantilever, 5, extension spring, 6, framed bent, 7, steel nail, 8, the chassis.
The specific embodiment
As shown in Figure 1, cross-under has semiaxis 1 in the back axle 2 of automobile, on the outer wall top of back axle 2 oil cylinder 3 is housed, and the oil circuit of this oil cylinder is communicated on the automobile oil circuit, and master cock can be arranged in the automobile cab, as the assist brake switch.Also be hinged with the spiral arm 4 of steel at the outer wall trailing flank of back axle 2, the front end face projection of spiral arm 4, the upper edge height exceeds the height that arranges of oil cylinder 3, makes piston rod in the oil cylinder 3 can push up the front end face of spiral arm 4.Be connected to framed bent 6 in the rear end of spiral arm 4, framed bent 6 is horizontal, and is parallel with back axle 2.Fix the downward steel nail 7 of row's nail point at framed bent 6.Posterior segment at spiral arm 4 has aperture, and the lower end of extension spring 5 is passed aperture and hooked spiral arm 4, and the upper end of extension spring 5 is hooked on the chassis 8 of automobile, forms machine drawing structure on the spiral arm.
Framed bent 6 and can have multi-formly with the connection mode of cantilever 4, a kind of is that framed bent 6 is bar structure, with the rear end of cantilever 4 be fixed and welded together (Fig. 1).Another kind is that framed bent 6 is to be provided with the triangle pipe link on cross bar top, is provided with axle sleeve (Fig. 2) at the top of triangle pipe link; The rearward end of cantilever 4 is made the spindle nose shape, and cross-under is in the described axle sleeve of framed bent 6, and the two grafting is combined together.The former is fixed connection structure, and auxiliary brake stroke is bigger; The latter is rotation connection structure, can realize the appropriate deflection of framed bent 6 relative spiral arms 4, so that local pawl brake gear also can take off reliably to ice-snow field or the snow drift of fitfull monoclinic phase projection, to realize reliable brake.Can be by active pull rod, limit pull rod or spacing extension spring etc. be set on framed bent 6, the level position hold mode during the control brake when the appropriate deflection of framed bent and non-brake.
Certainly also can adopt some other fit system to carry out being connected of framed bent and cantilever, these improve and design the protection domain that is this patent.
