Abstract

The utility model provides a low barycenter and difficult overturn tricycle, belonging to the field of the man power vehicle. The utility model adopts the method that a frame (1) is hung under an axle (6) through a bearing bush frame (2), and a carriage (7) is suspended on the frame (1) through a pressure spring (10), which causes the barycenter of the entire tricycle to be move downwards, and therefore, the overturn danger is reduced, and the tricycle body can be run stably and freely. The utility model has the advantages of easily, safety, and reliability.

Description

Rickshaw

The utility model belongs to the manpower transportation field.

At present, the vehicle frame of existing three-wheel vehicle all is to be pressed on the axletree of back wheels of vehicle, and railway carriage then is to be pressed on the vehicle frame.Like this, the center of gravity height, driving is unstable; Fastrunning or when curving has liftoff sense; As hollow or anxious turning, easily overturn.Therefore, the tumble injury people of regular meeting, danger close.

It is low that the purpose of this utility model provides a kind of center of gravity, the three-wheel vehicle of not prone to tip over.

The purpose of this utility model is achieved in that the bearing liner frame is hung vehicle frame 12 times, props railway carriage 7(with pressure spring 10 and see accompanying drawing 2 on vehicle frame 1 at axletree 6 overcoat bearing liner framves 2).Thereby reduce the railway carriage center of gravity, make its not prone to tip over.

The utility model is described in further detail below in conjunction with drawings and Examples.

Accompanying drawing 1 is an overall schematic of the present utility model.

Accompanying drawing 2 is trailing wheel part scheme drawings of the present utility model.

Wherein: 1, vehicle frame; 2, bearing liner frame; 3, holding screw; 4, clamp nut; 5, bearing bead; 6, axletree; 7, railway carriage; 8, connecting screw; 9, coupling nut; 10, pressure spring; 11, angle bar; 12, wheel.

As shown in Figure 2, the utility model utilizes bearing liner frame 2 to hang axletree 6 times, with holding screw 3 vehicle frame 1 is fixed on the bearing liner frame 2, thereby vehicle frame 1 is fixed under the axletree 6.Be lined with bearing bead 5 between bearing liner frame 2 and the axletree 6.

As shown in Figure 2, on vehicle frame 1, use connecting screw 8 and coupling nut's 9 fixation pressure springs 10 and railway carriage 7.7 of railway carriages are on pressure spring 10.And can utilize angle bar 11 support pressure springs 10.After railway carriage 7 was fixed on the pressure spring 10, when weightening finish in the case or meet the hollow vehicle body when jolting, railway carriage 7 can press down pressure spring 10 automatically, thereby lowers the center of gravity in good time, reaches the effect of timely balance.

The utility model adopts vehicle frame 1, be hung under the axletree 6 by bearing liner frame 2, and railway carriage 7 makes the car load down-shift of working center by the way of pressure spring 10 scaffolds on vehicle frame 1.When turning round, a lateral pressure spring 10 bears more weight, presses down automatically, and railway carriage 7 natures are inclined slightly to curving a side, has reduced the danger of overturning; When chance was jolted, railway carriage 7 center of gravity of can in good time sinking was automatically travelled steadily freely car body.

The utility model is light safety again in use, is the failure-free vehicle.

Claims (1)

1, a kind of three-wheel vehicle of exerting oneself is characterized in that: vehicle frame (1) is hung under the axletree (6) by bearing liner frame (2), and railway carriage (7) passes through pressure spring (10) scaffold on vehicle frame (1).
