Abstract

The utility model discloses a rhombus agricultural transport vehicle, which is characterized in that an assistant rear wheel is arranged at the rear of the vehicle body via a reach. The rhombus permutation of the utility model is that: an assistant wheel is arranged at the rear of the tricycle to relieve the front small wheel pressure; the pressure is divided scientifically and reasonably among four wheels, thus the overpressure of the front small wheel is relieved greatly and the stability of the vehicle is improved. For example, the center of gravity of the tricycles is moved backward when running slopes, which result in the front small wheel unsteady and leaning backward. The rhombus permutation agricultural tricycle adopts lengthening vehicle and large loading vehicle, the rhombus permutation has the same four points as the square permutation, but the endured pressure and resistance are different, the resistance of the rhombus permutation is less than that of the square permutation; the pressure of the front small wheel and the back small wheel is relatively small, which plays a role of balance and stability. The utility model has the advantages of strong stability, large loading, elegant appearance as well as practicability.

Description

The rhombus agriculture truck

Technical field the utility model relates to a kind of self-propelled vehicle, relates to a kind of rhombus agriculture truck specifically.

Our used transport trolley of background technology is three-wheel or four-wheel transport trolley basically, and three-wheel transporter uses flexibly, and is with low cost, but its poor stability, load carrying ability is little; Four-wheel transport trolley good stability, load carrying ability is big, but alerting ability is relatively poor, the cost height.

It is a kind of simple in structure, with low cost that the summary of the invention the purpose of this utility model is to provide, safety and stability, load carrying ability height, adaptable rhombus agriculture truck.

The purpose of this utility model is to realize by following technical scheme:

A kind of rhombus agriculture truck, its structural feature is: auxiliary rear wheel is installed by pitman in the back at car body.

Movable on the said pitman two oblique fulcrum bars are installed, the other end of two oblique fulcrum bars connects said auxiliary rear wheel, the fixing damping spring respectively at the two ends of said pitman.

On car body, fix two steady braces that connect auxiliary rear wheel.

Advantage of the present utility model is: the utility model is broken the square arrangement method, as automobile all is square arrangement, 4 of square arrangement are formed a plane, its stability is greater than 3 agricultural tricycles of forming the plane, and 3 resistances of forming a face are less than square arrangement, diamond array is exactly the pressure of steamboat before auxiliary rear wheel of design is alleviated behind the three-wheel vehicle, the past on request anterior displacement of rear main wheel science, the four-wheel pressure ratio is: left driving wheel=right driving wheel=preceding steamboat+auxiliary rear wheel, tripping power center of gravity wheel far away more, and the pressure that is subjected to is just more little, from the near more wheel of center of gravity and pressure is also just big more, relation between the design four-wheel of science is particularly important, the pressure of driving wheel is greater than the pressure of flower wheel, 2/3rds pressure is pressed on two driving wheels, 1/3rd pressure is shared on preceding steamboat and these two steamboats of auxiliary rear wheel, pressure with 2/3rds removes to promote 1/3rd pressure, the pressure division of labor suffered between four is scientific and reasonable, alleviated the excessive problem of pressure of preceding steamboat greatly, also improve the stability of car, move after the center of gravity when the last abrupt slope as three-wheel vehicle, steamboat shakiness before causing, the sense of layback is arranged, the diamond array agricultural tricycle, use adds long vehicle and the big vehicle of load-carrying, diamond array and square arrangement are four points equally, but pressure is different with resistance, the resistance of diamond array is less than square arrangement, steamboat and auxiliary rear wheel pressure are less before the rhombus car, play balance and stable effect, it is strong that it has stability, load carrying ability is big, practical characteristics elegant in appearance.

The further advantage of the utility model is: the bumper of agriculture truck is the damping of going up downforce at present, bumper of the present utility model is to be made of an equicrural triangle, its damping is horizontal, two jiaos of the big more tops of pressure are also just big more, following angle is simultaneously also big, the suffered pressure of the damping spring on the big more both sides of angle is also just big more, good damping effect.

Description of drawings Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the location diagram of the utility model wheel.

The specific embodiment as shown in Figure 1 and Figure 2, a kind of rhombus agriculture truck, pitman 4 is installed in back at car body, two sliding sleeves 2 are installed on the pitman, sliding sleeve connects oblique fulcrum bar 6 by bearing pin 3, the other end of two oblique fulcrum bars connects auxiliary rear wheel 7, and the fixing damping spring 1 respectively at the two ends of said pitman is fixed two steady braces 5 that connect auxiliary rear wheels on car body.

Claims

1, a kind of rhombus agriculture truck is characterized in that: auxiliary rear wheel (7) is installed by pitman (4) in the back at car body.

2, rhombus agriculture truck according to claim 1, it is characterized in that: movable two oblique fulcrum bars (6) of installing on the said pitman, the other end of two oblique fulcrum bars connects said auxiliary rear wheel, the fixing damping spring (1) respectively at the two ends of said pitman.

3, rhombus agriculture truck according to claim 1 is characterized in that: fix two steady braces (5) that connect auxiliary rear wheel on car body.
