Abstract

The utility model discloses an arm power drive tricycle vehicle by oneself, including frame, saddle, actuating mechanism, brake mechanism and steering mechanism. The bicycle is mainly characterized in that a transverse handle rod and a driving lever are driven by arm power to drive a linkage rod, a crank shaft, a chain wheel, a flywheel, a shaft and two rear wheels to move, so that the bicycle runs, a pedal plate, a front wheel frame and the front wheels are controlled by two feet to turn, and the bicycle is braked by a brake handle and a brake cable which are connected with a brake device. The utility model discloses simple structure is stable, easy to carry out, has increased a drive form for manpower tricycle.

Description

Arm force driven tricycle

Technical Field

The utility model relates to a manpower drive vehicle equipment, especially an arm power drive tricycle.

Background

The existing manpower-driven self-propelled tricycle is mostly driven by pedals, and only special vehicles such as disabled people and the like drive cranks to drive crankshafts, chains and the like by arm power shaking, and the driving form is not comprehensive.

Disclosure of Invention

In order to increase the driving form of the existing manpower tricycle, the utility model provides a new driving form of the tricycle driven by the arm force lifting and pressing operation.

The utility model provides a technical scheme that the problem adopted is: the transverse handle rod is lifted and pressed by the arm force, the driving lever connected with the transverse handle rod drives the linkage rod to move, the crank shaft and the chain wheel to do circular motion, and then the chain is driven to drive the sprocket flywheel, the wheel shaft and the rear wheel to do circular motion through chain transmission to drive the vehicle.

The number of the wheels is three, one of the wheels is arranged in the front and used for controlling the direction of the vehicle, and the other wheel is arranged in the rear and used for driving the vehicle and braking.

The mechanical parts are assembled together through the frame. The transverse handle rod of the driving lever is provided with a brake handle device which is connected to a brake device of a rear wheel axle through a brake cable. The turning of the vehicle is realized by controlling the front wheels through two feet.

The beneficial effects of the utility model are that, the utility model discloses technical scheme mechanical structure is simple common, and spare parts such as used chain wheel, chain, sprocket flywheel, brake spare part, saddle are the current ripe product in market, and stable in structure, scheme easy to implement have increased a drive form for manpower tricycle.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

FIG. 2 is a schematic sectional view taken along line A-A' of FIG. 1.

In the figure, 1, a frame, 2, a saddle, 3, a transverse handle rod, 4, a driving lever, 5, a linkage rod, 6, a crankshaft, 7, a chain wheel, 8, a chain, 9, a chain wheel flywheel, 10, a rear wheel, 11, a front wheel, 12, a pedal, 13, a brake handle, 14, a brake cable, 15, a brake device, 16, an axle, 17, a bearing group, 18, a front wheel frame and 19, a guide chain wheel are arranged.

Detailed Description

This scheme includes frame 1, saddle 2, actuating mechanism, brake mechanism and steering mechanism.

The arm force of the driving mechanism acts on a transverse handle rod 3 fixed on a driving lever 4, the driving lever 4 is driven to reciprocate by lifting and pressing the transverse handle rod 3, the driving lever 4 is movably connected with a frame 1, the driving lever 4 is movably connected and combined with a linkage rod 5 and drives the linkage rod 5 to move, the linkage rod 5 is movably connected and combined with a crank shaft 6, the crank shaft 6 and a chain wheel 7 are fixedly connected, the crank shaft 6 is movably connected with the frame 1, the linkage rod 5 drives the crank shaft 6 and the chain wheel 7 to do circular motion, the chain wheel 7 drives a chain 8 to move, the chain 8 changes the motion direction through a guide chain wheel 19, force is transmitted to the chain wheel flywheel 9 to enable the chain wheel flywheel 9 to do circular motion, the chain wheel flywheel 9 is fixed with a wheel shaft 16 and a rear wheel 10, and the wheel shaft 16 is movably connected with the frame 1, so that the rear wheel 10 does circular motion to drive the vehicle.

When the direction needs to be controlled, force on feet of a person acts on the pedal plates 12, the pedal plates 12 are fixedly connected with the front wheel frame 18, the front wheel frame 18 is connected with the frame 1 through the bearing group 17, the front wheel frame 18 is movably connected with the front wheels 11, and the force on the feet of the person is transmitted to the front wheels 11 through the pedal plates 12 and the front wheel frame 18 to enable the front wheels 11 to steer, so that the purpose of controlling the direction of a vehicle is achieved.

When the vehicle is required to be braked, force on hands acts on the brake handle 13, the force is transmitted to the brake device 15 through the brake cable 14, the wheel shaft 16 and the rear wheel 10 are prevented from continuing to do circular motion, and therefore the purpose of braking the vehicle is achieved, and the brake handle 13 is fixed on the cross handle rod 3.

The utility model discloses the during operation, the user takes on saddle 2 continuous with frame 1, and saddle 2 can height-adjusting as required, and both hands are held tight horizontal handle pole 3, and two pedals are on running-board 12, thereby do the activity drive vehicle of ordering about the vehicle motion.
