Description

Support type skid-proof and trap-proof device for motive vehicle

The utility model belongs to automobile-use and prevent that tire from skidding and prevent to be absorbed in the device of muddy highway on ice-snow field.

At present, automobile adopts iron chains anti-skidding and adhesive tape or low temperature resistant polyurethane etc. with anti-skid device more.The former destroys the road surface, damages tire; The latter costs an arm and a leg, is short in needed material, and the loading and unloading effort.Therefore influence its application.Chinese patent CN89210498.8 number a kind of automobile rotating anti-slip device is disclosed in the recent period again, it is mainly by rotating sprocket, principal arm, formations such as extension spring, have many iron chains on the rotating sprocket, when on ice and snow road, travelling, can put down sprocket wheel makes it to keep contacting with tire, iron chains is laid on the road surface, when on black road surface, travelling, sprocket wheel can be packed up and be fixed on the back axle, though this technology has overcome destruction ground-surface problem, but it still damages tire, and structure is also complicated, and cost is than higher, for having one section ice and snow is arranged on the black road surface, there is the situation of one section no ice and snow to use very inconvenience, particularly to thick snow road surface, muddy road surface is inapplicable, so its Applicable scope is little.

The utility model is at the situation of prior art, designs a kind ofly both to be applicable to that the ramp that freezes was anti-skidding, is applicable to again that road surfaces such as thick snow, mire, warm and sunny sand are anti-to fall into, and is simple in structure, easy to use, the anti-skidding anti-sinking device of automobile-use support type that cost is low.

The utility model is achieved by following manner: automobile-use support type skid-proof and trap-proof device, and comprise detent mechanism, support transmission device, its major technique feature is:

Said detent mechanism is by being fixed on the positioning plate on the big box plate directly over the vehicle wheels center and the slide rule cover on it of being connected, the location slide rule can slide up and down in the slide rule cover, slide rule lower end, location roll case and formation is rolled in interior location, wherein be shaped on the isometrical circular hole that two rows arrange according to certain rules respectively on positioning plate lower part and the location slide rule, they also can plurality of rows, as three rows, four rows etc., location slide rule and positioning plate can be connected by their cooresponding isometrical circular holes and bearing pin, according to concrete condition of service, can utilize bearing pin to locate is connected after isometrical circular hole on slide rule and the positioning plate aligns, it can be the integral multiple of a certain numerical value that circular hole on the slide rule of location moves the distance that aligns with respect to the circular hole on the positioning plate, in this way 3 millimeters integral multiple.

Said support transmission device is by passing through external axle, spindle nose fishplate bar and screw bolt and nut are fixed on the pivot arm on the wheel for motor vehicle semiaxis, pass through axle and bearing and sleeve pivotally attached strut with pivot arm, the steel spring that the outer upper end of sleeve is connected, and in the strut lower end and the middle and lower part horizontal fagging and the wire spring that are provided with constitute, wherein wire spring upper end is to be connected and horizontal fagging is passed in the lower end by nut, horizontal fagging is vertical with strut to be connected and the following of horizontal fagging can be provided with additional fagging, vertically being connected here can adopt welding also can adopt other industrial way commonly used, as being connected by screw etc.Above-mentioned situation is the situation at automobile (lorry), as shown in Figure 1, 2, then can carry out the relevant member of design and installation stationary positioned plate as the case may be for other self-propelled vehicle.

The utility model working process and principle are: the effect of detent mechanism is to determine before the strut action and the ground-surface angle, the effect of supporting mechanism is that the torque axis that the vehicle wheels semiaxis is exported is become the power that supported cart is advanced, and utilizes the bearing force conicity force parallel with the road surface to overcome resistance promotion self-propelled vehicle and advances.Because roll the location is to control before the strut action indirectly and the ground-surface angle by (can the adopt welding be connected) steel spring on sleeve that is connected, so also need before using at first pivot arm to be forwarded to directly over the vehicle wheels center, strut is overlapped with pivot arm, determine as required that then the location rolls down the distance of edge to steel spring, usually to freezing this distance of ramp generally between 1.8～2 centimetres, muddy, generally (value should be less than normal when the road surface was softer between 0.2～1 centimetre for this distance of the warm and sunny husky road surface of thick snow, otherwise should be bigger than normal), when this distance is determined back (can adjust sometimes during concrete certainly the use), check two rounds of location slide rule and positioning plate again, seek near a pair of corresponding aperture (it is 0～1.5 millimeter to the corresponding aperture distance between center line that present technique designs this) that overlaps, mobile slide rule will be located slide rule with bearing pin again after this is overlapped fully to corresponding aperture and will be fixed on the positioning plate.To freezing, avenge firmly the road surface, before using present technique, wire spring on the strut also need move to control position, be that the wire spring upper end is connected by nut, and the hole of horizontal fagging can be passed in the lower end, to guarantee with the road 55～60 ° desirable angle being arranged before strut supports, this is one of essential condition that realizes present technique.Fig. 9～12nd, the skidproof working process scheme drawing of present technique, wherein Fig. 9 is detent mechanism control the contact to earth situation of position of wire spring down, Figure 10 is wire spring lower end locating point (stopping reach), and Figure 11 is the position that horizontal fagging contacts to earth and begins to move, and Figure 12 is that strut supports the position that stops.Figure 13～16th, the anti-working process scheme drawing that falls into of present technique (remove wire spring and add additional fagging this moment), wherein Figure 13 is the situation in detent mechanism control lower supporting rod location, roll pressure to steel spring by location and make strut, horizontal fagging overcome resistance to arrive this shown position this moment, and the purpose that adds additional fagging here is increase and ground-surface area of contact.Figure 14 is the position that strut begins to move, and Figure 15 is the situation of pivot arm when changeing the half cycle rear pole and supporting, and Figure 16 is the position of strut action when stopping, and finishes the working process of present technique by said process.

The utility model is compared with prior art, has simple in structurely, easy to use, and Applicable scope is big, both has been applicable to that the ramp that freezes is anti-skidding, is applicable to thick snow, mire again, warm and sunny husky ground-surface is anti-falls into, processing and manufacturing easily, characteristics such as cost is low.
