Abstract
A tricycle is composed of split mechanism consisting of front axle, back axle, tension wheel mechanism consisting of tension wheel, self-locking pawl, control cable and brake body, back axle mechanism consisting of back axle and wheels, limit stop block on axle, and balance spring set between back axle and balance arm, and back axle mechanism consisting of tension wheel, chain and flywheel. The utility model discloses rational in infrastructure, easy control, difficult rollover.
Description
The utility model relates to a kind of three-wheel vehicle.
At present, common three-wheel vehicle is owing to front vehicle frame connects with back vehicle frame rigidity, when riding, handlebar is stiff, be difficult to grasp control, when running into Uneven road and inclination under steam, bicyclist self center of gravity will depart from the car body longitudinal plane of symmetry, the bicyclist follows wigwag motion or inclination, makes the bicyclist in tension; , excessive velocities little at turn radius, when transformation is too urgent, as control improper because its action of centrifugal force very easily causes roll-over accident; Moreover people that usually can be by bike often not necessarily can be by tricycle.
The purpose of this utility model provides the three-wheel vehicle of a kind of modern design, rational in infrastructure, easy to control, not prone to tip over, it is applicable to the small-sized transportation of family, outer trip, the worker is on and off duty and industrial and mining enterprises do patrol and examine, the transport facility of plant maintenance.
The purpose of this utility model realizes by following measure: a kind of three-wheel vehicle, it comprises by split mechanism, hind axle mechanism, tension wheel mechanism and the line self-locking mechanism of stopping is formed, split mechanism is connected by the chain axle sleeve with the aftercarriage support by the flat pipe of front vehicle body stamen axle, flat pipe stamen axle is provided with positive stop, the balance spring group is housed between aftercarriage support and the equilibrium arm to be constituted, can make the car body held stationary that swings and reset, in the process of riding, when running into turning or Uneven road and inclination, because freely swinging relatively of front and back car body, can utilize the centre-of gravity shift of human body, overcome centnifugal force, the total maintenance of two trailing wheels contacts with ground, make bicyclist and institute's cargo held stationary, not prone to tip over; Hind axle mechanism is by constituting from supporting the hind axle and the wheel that connect the aftercarriage support, and wheel can be joined ordinary bicycle wheel or electric wheel hub, makes it to become electro-tricycle; Tension wheel mechanism is made of the chain and the flywheel of tension wheel and tight engagement, when chain swings with front vehicle body, because tension wheel makes chain and flywheel reliably nibble closing, is unlikely to chain releasing and kills; Line is stopped self-locking mechanism by brake lever self-locking pawl, control wire and be attached thereto the body of stopping that connects and constitute, when the brake lever reinforcing surmounts latching point, make the self-locking of self-locking pawl, make the body of stopping be in the tight state of stopping by control wire, unclamp self-locking, by spring the self-locking pawl is resetted, make the body of stopping be in releasing orientation, also can make three-wheel vehicle when withdraw from use, be in self-locking state safety and park by control wire.
The utility model is rational in infrastructure, handsome in appearance, easy to control, the difficult overturning, and it is free and relaxed to ride, strong with the attachments of a bicycle interchangeability, can be in self-locking state when withdraw from use, safe and reliable, has popularizing value.
Below in conjunction with drawings and Examples in detail the utility model is described in detail.
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model split structural scheme of mechanism.
Fig. 3 is the utility model hind axle structural scheme of mechanism.
Fig. 4 is the utility model tension wheel structural scheme of mechanism.
Fig. 5 is the utility model line self-locking mechanism scheme drawing of stopping.
Shown in Fig. 1～5, a kind of three-wheel vehicle, it comprises by split mechanism, hind axle mechanism, tension wheel mechanism and the line self-locking mechanism of stopping and forming, its mainly be split mechanism by the flat pipe of front vehicle body stamen axle (1) and aftercarriage support (2) by hinge shaft sleeve link, flat pipe stamen axle (1) is provided with balance spring group formation is housed between positive stop (5), aftercarriage support (2) and the equilibrium arm (3); Hind axle mechanism is made of hind axle (6) and the wheel (7) that separable support connects aftercarriage support (2); Tension wheel mechanism is made of with flywheel (10) the chain (9) of tension wheel (8) and tight engagement; Line is stopped self-locking mechanism by brake lever (11), self-locking pawl (12), control wire (13) and be attached thereto the body of stopping (14) that connects and constitute.
Claims (1)
1. three-wheel vehicle, it is made up of split mechanism, hind axle mechanism, tension wheel mechanism and the line self-locking mechanism of stopping, and it is characterized in that: split mechanism by front vehicle body flat pipe stamen axle (1) and aftercarriage support (2) by hinge shaft sleeve link, flat pipe stamen axle (1) is provided with positive stop (5), aftercarriage support (2) constitutes to the balance spring group is housed with equilibrium arm (3); Hind axle mechanism is made of hind axle (6) and the wheel (7) that separable support connects aftercarriage support (2); Tension wheel mechanism is made of with flywheel (10) the chain (9) of tension wheel (8) and tight engagement; Line is stopped self-locking mechanism by brake lever (11), self-locking pawl (12), control wire (13) and be attached thereto the body of stopping (14) that connects and constitute.
