Abstract
The utility model relates to an accelerating and boosting device for a manpower vehicle. The utility model is characterized in that a fixed frame 13 is fixed on a rear wheel supporting frame of a manpower vehicle; the rear wheel hub 1 of the manpower wheel is provided with a small chainwheel 2; the small chainwheel 2 is connected with a large chainwheel 4 by a chain 3; the front brake or the rear brake of the manpower vehicle is demounted; a wire rope 8 is fixed on a vehicle brake handlebar 6; the vehicle brake handlebar 6 is exerted by force; a big gear 16 and a small gear 17 which are meshed rotate by the wire rope 8, so that the rear wheel of the bicycle can boost and accelerate.
Description
The utility model relates to rickshaw and adds the speed booster technical field.
The rickshaw that uses at present and make quickens and reinforcement is realized by riding of people fully, the strength of staff is not used fully, thereby rickshaw acceleration and reinforcement are restricted.
The purpose of this utility model is that a kind of rickshaw of design adds speed booster, and the strength of staff also is applied in the acceleration and reinforcement of rickshaw.
The utility model is achieved in that fixed mount 13 is fixed on the rickshaw trailing wheel bearing support, minor sprocket 2 is fixed on the rickshaw rear-wheel hub 1, steel rope 8 is fixed on brake on 6, hinge wheel 4 is connected with minor sprocket 2 by chain 3, axle I5 is contained on the fixed mount 13 by pair of bearings I14, the fixing hinge wheel 4 by key II12 is arranged on axle I5, miniature gears 17 and big gear wheel 16 engagements, miniature gears 17 is contained on the I5 by bearing I II18, clockwork spring 19 is housed in the miniature gears 17, clockwork spring 19 outermost end are fixed in the miniature gears 17, its inner terminal is fixed on the I5, the ratchet 20 that a pair of ratchet I21 is arranged on the big gear wheel 16 and be fixed on the II11 by key III24 meshes, and spring 22 1 ends are fixed on the ratchet 20, and its other end is fixed on the fixed mount 13, ratchet II23 is fixed on the fixed mount 13 and meshes with big toothed chain wheel 16, axle II11 passes spring 22 and is contained on the fixed mount 13 by pair of bearings II15, and rope sheave 9 is contained on the II11 by key I10, is wound with steel rope 8 on the rope sheave 9.
The utility model has the advantages that: make rickshaw speed faster, load carrying ability increases.
Below in conjunction with accompanying drawing, the utility model is described further with embodiment:
Accompanying drawing is the utility model structural representation.
In the accompanying drawing 1, the rickshaw rear-wheel hub, 2, minor sprocket, 3, chain, 4, hinge wheel, 5, axle I, 6, the brake handle, 7, handlebar, 8, steel rope, 9, rope sheave, 10, key I, 11, axle II, 12, key II, 13, fixed mount, 14, bearing I, 15, bearing I I, 16, big gear wheel, 17, miniature gears, 18, bearing I II, 19, clockwork spring, 20, ratchet, 21, ratchet I, 22, spring, 23, ratchet II, 24, key III.
Fixed mount 13 is fixed on the rickshaw trailing wheel bearing support, minor sprocket 2 is fixed on the rickshaw rear-wheel hub 1, the front brake or the back brake gear of rickshaw are unloaded, steel rope 8 is fixed on front brake or back brake on 6, hinge wheel 4 is connected with minor sprocket 2 by chain 3, firmly hold brake 6 this moment, driving axle II11 by steel rope 8 rotates, axle III11 drives ratchet 20 and rotates, because the contrary tooth engagement of ratchet 20 and ratchet I21, ratchet I21 is on big gear wheel 16, and big gear wheel 16 rotation driving pinions 17 also rotate, and spring 22 is owing to the rotation of ratchet 20 is tightened, this moment, ratchet II23 and big gear wheel 16 were along the tooth engagement, do not influence big gear wheel 16 and rotate, miniature gears 17 tightens clockwork spring 19 makes an I5 drive hinge wheel 4 rotations, drives the rickshaw trailing wheels by chain 3 and minor sprocket 2 and quickens and reinforcements; When staff unclamps brake 6 the time, spring 22 discharges elastic force makes rope sheave 9 revolution steel ropes 8 once more on rope sheave 9, because hand of rotation changes, ratchet 20 and ratchet I21 are along the tooth engagement, have only ratchet 20 to rotate, big gear wheel 16 is not rotated, and also drives big gear wheel 16 rotations for preventing that miniature gears 17 rotates under clockwork spring 19 elastic force effects, because ratchet II23 and big gear wheel do not rotate big gear wheel 16 for contrary tooth meshes 16 this moments.Make brake 6 reinforcings again, course of action is the same, makes brake can finish the process of rickshaw with hand reinforcing and speedup to 6 reinforcings with unclamping repeatedly.
