Detailed description of the invention

Referring to Fig. 1 to Fig. 4, this utility model provides the Anti-side-turning device on a kind of tricycle, is installed on tricycle Middle part, connects main car frame and Rear frame, main car frame arranges a front-wheel, Rear frame arranges two trailing wheels；Anti-rollover Device includes housing 1 and pivot 2, and housing is made up of with lower cover 4 upper cover 3, is combined by bearing between described pivot 2 and housing 1 Connecting, bearing combination includes big bearing 5 and little bearing 6, is respectively at front end and the rear end of housing 1, thus realizes housing 1 around pivot Axle 2 rotates；Be on described pivot 2 between big bearing 5 and little bearing 6 and be provided with runner 7, described runner 7 be provided with two adjacent And accommodating end face 8 in a certain angle, be respectively equipped with valve rubber 9 between two accommodating end faces 8 and housing 1 inwall, work as three-wheel When car is turned, main car frame drives housing 1 and pivot 2 that the rotation around axis of relative angle occurs, and runner 7 occurs to turn with pivot 2 Time dynamic, one of them accommodating end face 8 extrudes the valve rubber 9 of correspondence, and valve rubber 9 is squeezed occurs shape between housing 1 and runner 7 Become, thus buffer the centrifugal force produced when tricycle is turned；Described pivot 2 end is fixing with external connection support 10 to be connected, outward Portion connects the fixing Rear frame that connects of support 10, and housing 1 is fixing connects main car frame, thus realizes the phase between main car frame with Rear frame To rotation.

Being additionally provided with handbrake mechanism on described pivot 2, described handbrake mechanism includes fixing tooth 11, the latch being located on pivot 2 12 and be located on housing 1 and can realize rotate power transmission shaft 13, described latch 12 one end has and fixes the wheel that tooth 11 engages Tooth 14, the other end is hinged on housing 1 by jointed shaft 15；One end of power transmission shaft 13 is provided with cam bit 16, and the other end is fixing to be drawn Ring 17, described draw ring 17 is in outside housing 1, is provided with two installing holes 18 at draw ring 17 two ends；Described cam bit 16 is by passing Dynamic chain 19 realizes being connected with the gear teeth 14 side of latch 12；When rotating counterclockwise draw ring 17, cam bit 16 pulls latch outwardly 12, the gear teeth 14 depart from fixing tooth 11；When rotating clockwise draw ring 17, cam bit 16 promotes latch 12 inwardly, and the gear teeth 14 engagement is solid Determine tooth 11.

As it is shown in figure 5, described runner 7 is the extrusion with triangle as cross section, center is provided with axis hole 21, with valve rubber 9 Two accommodating end faces 8 of coupling are to cave inward and curved cancave cambered surface 20, and two cancave cambered surfaces 20 are symmetrical structure.

When tricycle is turned, with housing 1 connect the relative Rear frame being connected with external connection support 10 of main car frame around Pivot 2 rotates, and when turning to the left, as shown in Figure 6, Rear frame turns right relative to main car frame, and the revolver in Rear frame has relatively Main car frame climbs away ground turned-out trend, and centrifugal force when this trend is owing to turning to the left produces, and runner 7 extrudes The rubber blanket 9 on right side, rubber blanket 9 deforms upon, and offsets and absorbs centrifugal force；When bending to right, as it is shown in fig. 7, Rear frame Main car frame relatively turns left, and the right wheel in Rear frame has relative main car frame to climb away ground turned-out trend, and this becomes Centrifugal force when gesture is owing to bending to right produces, the rubber blanket 9 on the left of runner 7 extruding, and rubber blanket 9 deforms upon, and offsets also Absorb centrifugal force；So that the centrifugal force of tricycle and occupant is cancelled out each other with its gravity, three wheels contact all the time Ground, adds the ground connection gross area of tire, effectively prevents tricycle rollover and breaks away.

When vehicle is kept straight in smooth-riding surface, Anti-side-turning device is in normal condition, as it is shown in figure 5, during runner 7 is in Position, both sides rubber blanket 9 is not compact.

When the vehicle is running, parking brake is in disengaged condition, and the gear teeth 14 depart from fixing tooth 11, as shown in Figure 2；And when vehicle stops Time only, by pulling the parking brake pull bar of vehicle front, parking brake pull bar pulls connection steel bar, and steel bar drives draw ring 17, and draw ring 17 carries Moving cam sheet 16 promotes latch 12 inwardly, and the gear teeth 14 rotate around the jointed shaft 15 of latch 12 and finally engage fixing tooth 11, make pivot Axle 2 forms state of checking, and limits swinging of vehicle.

The Anti-side-turning device on a kind of tricycle provided this utility model embodiment above is described in detail, Principle of the present utility model and embodiment are set forth by specific case used herein, and the explanation of above example is only It is to be adapted to assist in the technical scheme understood disclosed in this utility model；Simultaneously for one of ordinary skill in the art, according to this The thought of utility model, the most all will change, in sum, and this specification content Should not be construed as restriction of the present utility model.
