Abstract
The utility model discloses a kind of diamond type changeable wheel track mechanism, by castellated shaft and the telescopic shaft that forms, push rod, the control mechanism of screw rod and nut composition and unilateral bearing composition, whole telescoping mechanism is connected with the wheel hub of wheel by unilateral bearing, castellated shaft is connected with three abutments by the second bearing, three abutments, nut is all hinged with push rod, second bearing passes through retainer ring spacing, telescopic shaft, control mechanism passes through clutch shaft bearing, second bearing, 3rd bearing and the first bearing and vehicle frame are connected, castellated shaft can accept the power that propulsion source transmits, thus castellated shaft is rotated, due to the character of the single direction rotation of unilateral bearing, and then give wheel power, vehicle is advanced.When vehicle needs to change wheelspan time, shake screw rod, because the rotation direction of screw rod two ends motion thread is contrary, can make nut simultaneously near or away from, by the deformability of diamond structure, push rod can be made to drive support and then drive castellated shaft to move, finally make wheel move, reach the object changing wheelspan.
Description
Technical field
The utility model relates to a kind of structure changing wheelspan, particularly a kind of diamond type changeable wheel track mechanism for miniature energy-saving car.
Background technology
The wheelspan of current vehicle is all immutable, and when running into comparatively rugged road surface and more anxious bend, vehicle stability is not enough; And when running into comparatively narrow lane face or parking, wider wheelspan can affect alerting ability.
Utility model content
The utility model object is to provide a kind of diamond type changeable wheel track mechanism for miniature energy-saving car.
The utility model is by telescopic shaft, control mechanism and unilateral bearing composition, telescopic shaft is made up of castellated shaft and spline housing, control mechanism is by push rod, screw rod and nut composition, telescopic shaft is connected with the wheel hub of wheel by unilateral bearing with control mechanism, castellated shaft is connected with three abutments by the second bearing, three abutments, nut is all hinged with push rod, second bearing passes through retainer ring spacing, telescopic shaft, control mechanism passes through clutch shaft bearing, second bearing, 3rd bearing and the first bearing and vehicle frame are connected, spline housing can accept the power that propulsion source transmits, thus castellated shaft is rotated, due to the character of the single direction rotation of unilateral bearing, and then give wheel power, vehicle is advanced.Due to the character of unilateral bearing single direction rotation, at Ackermann steer angle, two sidecar wheels slide separately, are independent of each other, and achieve the function of differential.When vehicle needs to change wheelspan time, shake screw rod, because the rotation direction of screw rod two ends motion thread is contrary, can make nut simultaneously near or away from, four push rods and two three abutments form diamond structure, by the deformability of diamond structure, push rod can be made to drive three abutments and then drive castellated shaft to move, finally make wheel move, reach the object changing wheelspan.
The beneficial effects of the utility model are:
The change of wheelspan is controlled by the screw rod contrary with two sections of rotation directions, comparatively laborsaving, and due to the self-locking character of worm drive, eliminate lockable mechanism, the rotation of axletree and the change of wheelspan are independent of each other, and the single direction rotation character of unilateral bearing makes this mechanism have differential ability.Mechanism is symmetrical, and two sidecar wheel amount of movements are equal.Purely mechanical structure, convenient and strength-saving.
Accompanying drawing explanation
Fig. 1 is schematic perspective view of the present utility model.
Fig. 2 is perspective exploded view of the present utility model.
In figure: 101-wheel, 102-castellated shaft, 103-push rod, 104-first bearing, 105-spline housing, 106-screw rod, 107-nut, 201-unilateral bearing, 202-clutch shaft bearing, 203-second bearing, 204-second bearing, 205-three abutments, 206-the 3rd bearing.
Detailed description of the invention
Refer to shown in Fig. 1 and Fig. 2, the utility model is by telescopic shaft, control mechanism and unilateral bearing 201 form, telescopic shaft is made up of castellated shaft 102 and spline housing 105, control mechanism is by push rod 103, screw rod 106 and nut 107 form, telescopic shaft is connected by the wheel hub of unilateral bearing 201 with wheel 101 with control mechanism, castellated shaft 102 is connected with three abutments 205 by the second bearing 204, three abutments 205, nut 107 is all hinged with push rod 103, second bearing 204 passes through retainer ring spacing, telescopic shaft, control mechanism is by clutch shaft bearing 202, second bearing 203, 3 206 bearing and the first bearing 104 are connected with vehicle frame, spline housing 105 can accept the power that propulsion source transmits, thus castellated shaft 102 is rotated, due to the character of the single direction rotation of unilateral bearing 201, and then give wheel power, vehicle is advanced.Due to the character of unilateral bearing 201 single direction rotation, at Ackermann steer angle, two sidecar wheels slide separately, are independent of each other, and achieve the function of differential.When vehicle needs to change wheelspan time, shake screw rod 106, because the rotation direction of screw rod 106 two ends motion thread is contrary, can make nut 107 simultaneously near or away from, four push rods 103 and two three abutments 205 form diamond structure, by the deformability of diamond structure, push rod 103 can be made to drive three abutments 205 and then drive castellated shaft 102 to move, finally make wheel 101 move, reach the object changing wheelspan.
