Abstract
The utility model discloses a driving and braking device of a tricycle, which mainly comprises wheels, tricycle shafts, bearings, brake discs and rotary ratchets, wherein the tricycle shafts and the bearings are arranged at the centers of the wheels; the brake discs and the rotary ratchets are arranged on the bearings; rear wheels of the tricycle are respectively provided with the brake discs and the rotary ratchets. The utility model improves the driving and the braking effects of the tricycle, reduces the labor intensity, enhances the climbing capacity and the turning flexibility, and extends the long service life. The utility model is mainly suitable for man-power tricycles.
Description
The utility model relates to a kind of three-wheel vehicle and drives and brake equipment.
At the manual tricycle that uses at present, its driving and brake equipment mostly are the centres that driven wheel is installed in back cart axle, with brake equipment be installed in the centre of back cart axle or wherein a wheel wheel in the heart.The major defect of this constructional device is a propulsive effort, and braking force is inhomogeneous, causes vehicle body not steady, and it is poor to drive braking effect.
The purpose of this utility model provides a kind of reasonable in design, and is simple in structure, can overcome above-mentioned shortcoming, and the three-wheel vehicle of driving and good braking effect drives and brake equipment.
The utility model is that three-wheel vehicle drives and brake equipment, mainly includes wheel, is located at the axletree of wheel center and places the bearing in the outer garden of axletree to form.Also comprise placing on the bearing, be loaded on the brake disc and the Drive ratchet of two wheel two sides behind the three-wheel vehicle respectively.
The utility model compared with prior art has following remarkable advantage and good effect.The one, the setting of Drive ratchet, it is laborsaving that three-wheel vehicle is driven, and improves moving velocity and hill climbing ability.The actuating device of symmetry reduces the distortion of vehicle body, prolongs the service life of three-wheel vehicle.The 2nd, being symmetrical arranged of brake disc braked flexibly three-wheel vehicle under steam, turns steadily, improves the traffic safety effect.
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is the utility model integral structure and installation site figure.
Fig. 2 is the utility model actuating device cut-away view.
Fig. 3 is the utility model brake equipment cut-away view.
As shown in Figure 1, the utility model mainly comprises wheel 1, and the core wheel of wheel 1 is provided with bearing 3 in (6), and two ends of axletree 2 place respectively in the bearing 3, and two wheels 1 are associated in together.The centre of axletree 2 also is provided with driving chain wheel 14, and brake disc 4 and Drive ratchet 5 are placed in the both sides of the core wheel 6 of each wheel 1 respectively, and brake disc 4 is fixed on the bearing of establishing in the dried core wheel 63, and 5 of Drive ratchets are fixed on axletree 2 and the core wheel 6.5 of described Drive ratchets are made up of the ratchet shell 7 ratchet hearts 8, and the interior garden of ratchet shell 7 is provided with mixes pearl 9 and ratchet sour jujube 10, and ratchet also is provided with the transmission tip 11 in the heart, Drive ratchet be separately fixed at nut 12 and screw 13 on the not end of axletree 2 with core wheel 6 on.Thereby make axletree 2 come geared wheel 1 by Drive ratchet 5.When three-wheel vehicle drove, with axletree 2 transmissions, axletree 2 drove wheel 1 to overtake by Drive ratchet 5 to driving chain by driving chain wheel 14.When car is turned,, reach flexible turning because the unidirectional rotation of Drive ratchet 5 makes the speed of two wheels 1 form differential.Because of brake disc 4 has 2 to be mounted respectively on each wheel 1, improved braking effect.
The utility model can be widely used in manual tricycle.
