Description
The utility model relates to a kind of electric boosted trishaw.
Sale at present and the electric boosted trishaw that uses, all by handlebar, front fork, front-wheel, vehicle frame, hind axle, rear main wheel, back follower, pedal transmission mechanism, compositions such as electrical motor and servodrive mechanism and stop mechanism, but mainly there is following point in the process of moving in the electric boosted trishaw of this kind structure: 1. since hind axle one end captive joint with wheel hub and tire thereof and become rear main wheel, being used for driving three-wheel vehicle travels, the other end of hind axle and its wheel hub and tire are connected to become the back follower by bearing, be used for making three-wheel vehicle to make circular movement, to reach the purpose of turning.External contracting drum brake is installed on the hind axle of three-wheel vehicle, glancing impact, make brake collar embrace the brake wheel that is connected with hind axle by brake handle and pull bar, thereby the rear main wheel of captiveing joint with hind axle is stopped operating, but only braked a rear main wheel, then follower is under the effect of the force of inertia that car load travels, can continue to slide forward, make car load produce a side direction moment, not only reduced braking effect, and to cause car load be that the center of circle causes that car load walks crosswise with the rear main wheel, when emergency braking, the also traffic accident that can overturn causes braking dangerous reliable.2. owing to adopt external contracting drum brake, car load is glancing impact in the way of going up a slope, because of deadweight produces the power to downhill running, thereby make brake collar reduce to the friction force of brake wheel, brake collar can't rouse by braking with locked wheels, add that the back follower can't brake, thereby cause car load can slip car on the ramp, it is unreliable to brake.3. the braking employing is hand braking, and when emergency braking, handle is grasped direction on the other hand, and brake handle under another hand can influence braking effect, causes braking force not enough, and operating difficulties, is unfavorable for safe driving.
The purpose of this utility model provides the electric boosted trishaw of a kind of brake safe failure-free.
It is more reliable that the further purpose of the utility model provides a kind of braking, easy to operate electric boosted trishaw.
The technical scheme that realizes the utility model purpose is: a kind of electric boosted trishaw, has handlebar, front fork, front-wheel, vehicle frame, rear main wheel, pedal, crank, back follower, hind axle, brake handle, front tension bar and rebound, by preceding sprocket wheel, the pedal transmission mechanism that chain and flywheel are formed, electrical motor and by drive sprocket, the servodrive mechanism that chain and passive sprocket wheel are formed, and the rear main wheel end of following improvement: a at hind axle arranged, brake shoe carrier is by bearing and hind axle load, brake shoe carrier is captiveed joint with steel spring or vehicle frame, brake shoe assembly be installed in the brake wheel and with the brake shoe carrier load, the drive hubs of brake wheel and rear main wheel is made one, and drive hubs is captiveed joint with hind axle; B is at the back follower end of hind axle, brake shoe carrier is by bearing and hind axle load, brake shoe carrier is captiveed joint with steel spring or vehicle frame, brake shoe assembly be installed in the brake wheel and with the brake shoe carrier load, brake wheel is made one with the passive wheel hub of back follower, and passive wheel hub is by bearing and hind axle load; C. the pivoted arm of the camshaft on two brake shoe carriers respectively by back stay, side rocking arm, transition axis, intermediate rockers and in pull bar and rebound load, and transition axis is by shaft seat and vehicle frame load.
The technical scheme that realizes further purpose of the present utility model is: be fixedly connected with brake pedal on the brake handle.
Advantage after the employing technique scheme is: because the passive wheel hub of the drive hubs of the rear main wheel at hind axle two ends and back follower fuses with brake wheel respectively, car load is at the glancing impact that travels, by brake handle and Transmission, camshaft in the brake wheel is rotated, cam spreading brake shoe on the camshaft, make brake shoe and brake wheel friction, force brake wheel to stop operating, thereby rear main wheel and back follower have been braked simultaneously, car load can not produce side direction moment like this, both improved braking effect, do not walked crosswise or the traffic accident of overturning in the time of can not making the car load emergency braking again, accomplished that brake safe was reliable.2. braking in car load is going up a slope the way, though car load also has a power that slides downwards, brake shoe rises at the inwall of brake wheel, thereby can not reduce the friction force of brake shoe and brake wheel, be that two-wheel is braked simultaneously in addition, thus can not cause car load on the ramp, to slip car, so braking is reliable.3. after adding brake pedal on the brake handle, during service brake, can with the hands hold handlebar,, not only can guarantee braking effect, make the rapid pulsation-free braking of car load with foot-operated brake pedal down, and easy to operate, more guaranteed the safety of driving a vehicle.
The utility model is described in further detail below in conjunction with embodiment that accompanying drawing provides.
