The utility model be a kind of on the ice and snow road or on the muddy road surface, be used for self-propelled vehicle, be particularly useful for operational, the adjustable automatic anti-slip device of automobile (trailer).

In known automobile (trailer), ice snow covered pavement is anti-skidding at present still can not meet the demands.The unit that has just stops transport when running into ice snow covered pavement, promptly is the automobile (trailer) of not stopping transport, and can not improve due average speed per hour, can not ensure safety, and influences economic construction, influences people's lives.Especially for operational automobile (trailer), under the ice snow covered pavement condition, training quality and fight capability are affected, be directly connected to national defense construction.

Task of the present utility model need propose problem according to the skidproof task of automobile (trailer) ice snow covered pavement exactly, passes through analytical investigation, grasp its ice snow covered pavement travel in the characteristics of " wheel is easily braked, and the car difficulty is stopped ", use its rule, careful design, well-designed achievement of solving.

The target that solves anti-skidding task is, makes its skidproof effect approach the braking effect of non-ice and snow road, especially stops sideslip, ensures driving safety.Simultaneously, improve speed per hour as far as possible, reduce consumption of fuel.

Solving skidproof method is, make a kind of at present more satisfactory anti-skid device, promptly provided by the utility model, the adjustable automatic anti-slip device of automobile (trailer).

This device is as long as just can realize with common apparatus and technology.

Figure I is the outside drawing of automobile (trailer) dress with this device.It is flat garden body, and its thickness is≤150mm to be fixed in the lateral wheel automatic anti-slip.It is with the eyelet bolt tension, and (be close to, and other fixed forms are fixed by the single-wheel location with rim for automobile wheel inboard (two-wheel) or with the spoke outside for fixing seat cover.In the ordinary course of things, automobile (trailer) is as long as the trailing wheel dress is used (figure Ia).When often travelling on bigger ice and snow highway section, slope (this road surface almost is not existed), front-wheel also should the symmetry dress with (figure Ib).

Fig. 2 is the facing and left pseudosection of structure, work and use of this device.It is made of drive plate and fixed mechanism (9), checkered plate (11), driver plate (8,12,18), spring (16) slide block (20), fixed cover (21), adjustment cover (22), adjustment driver plate (10) and cover plate major metal spares such as (23).It is characterized in that with checkered plate (11), driver plate (8,12,18), spring (16), adjust driver plate (10) and slide block (20) etc., form several work piece groups (Fig. 3); (axially), (radially) some cover associated working part group (Fig. 4) of symmetry that each work piece group is overlapping with identical work piece group composition.This associated working part group and fixed cover (21) and adjustment cover (22 cooperatings, under the effect of slide block (20) centnifugal force and spring (16) expansion force, make the two ends that checkered plate (11) are housed of its symmetry, and the checkered plate (11) in the garden week of whole device produces identical flexible stroke simultaneously.

It is lubricated, mechanical with lithium base grease or graphite calcium base grease, and the long life uses, the adjustable automatic anti-slip device that replaceable wearing parts is repaired.

This device be with the vehicle wheel rotational speed of automobile (trailer) or quite speed per hour be foundation, according to ice snow covered pavement braking rule, make slide block (20) produce centnifugal force by certain vehicle wheel rotational speed, by driver plate group (8,12,18) or adjustment driver plate (10) transferring power that has annular (or other shapes), by the support of fixed cover (21) and the telescopic action of spring (16), the expanding-contracting action of automatic guidance checkered plate (11).

When this device is passed in 25 kilometers of the suitable speed per hours at automobile (trailer) dead ship condition and wheel (wheel of 650-16 tyre series was 2.9 circle/seconds), slide block (20) centnifugal force does not produce, or it is less to produce centnifugal force, at this moment, checkered plate (11) is by the support of fixed cover (21) and the expansion force of spring (16), and overcoming centnifugal force, to stretch out this device external.At this moment, the diameter of the non-landing ground of maximum gauge 〉=wheel of this device.Because tire heavy burden deflection is 7-30mm on the wheel, so cutter head and ice and snow road on the checkered plate at this position (11) are meshing.Because vehicle wheel rotational speed is lower than speed per hour or stops operating, make the cutter head on the checkered plate (11) after meshing produce cutting action to it again, and this meshing and cutting action, replaced the adhesive ability that should have of wheel and ice and snow road, thereby, possessed anti-skidding condition.So this moment, the landing ground position of this device was in anti-skidding state.And implement anti-skidding effectively.

When the suitable speed per hour of vehicle wheel rotational speed was more than 25 kilometers, because the raising of vehicle wheel rotational speed, the centnifugal force that slide block (20) is produced increased; This centnifugal force drives checkered plate (11), the compression spring (16) that cover (21) supports that is fixed by driver plate group (8,12,18), makes checkered plate (11) this device body interior (Fig. 2) of withdrawing.Because checkered plate (11) broken away from ice and snow road, removed the meshing and cutting action of checkered plate power head to ice and snow road, reduced the rolling resistance of wheel and meshing resistance etc., at this moment, this device reduces consumption of fuel and removes anti-skidding for improving average speed per hour.

When vehicle wheel rotational speed quite slows down or stops, because slide block (20) centnifugal force from large to small promptly, is not had by little change.At this moment, it is external that checkered plate (11) stretches out this device again, implements anti-skidding for shortening retarding travel or time.

Work and so forth, automobile (trailer) travelled on ice and snow road, implement anti-skidding effectively with remove in time anti-skidding.

Owing to operational needs or owing to the imperative duty of certain situation is decided, when needs permanent (uninterruptedly) are anti-skidding, or since certain situation do not need when anti-skidding, can pass through special tool left rotation and right rotation adjustment cover (22), at this moment, adjust cover (22) and adjust driver plate (10) by the drive of the connecting pin in the deep-slotted chip breaker, this is adjusted driver plate (10) and links to each other with driver plate (12,18) respectively.When adjusting cover anti-clockwise rotation driver plate (12) when pulled, force checkered plate (10) by compression spring (16), checkered plate (11) is withdrawn in this device body.Otherwise driver plate (18) forces slide block (20) to move on to minimum (inoperative) position by the maximum centrifugal force position when pulled, and other end checkered plate (11) is by the extension effect of spring (16), and it is external to stretch out this device.If respectively (can not simultaneously) fix, just can realize anti-skidding or forever not skidproof purpose forever.
