Abstract

The utility model relates to a chassis for motor-driving tricycles, which is composed of two longitudinal main beams and a plurality of transverse beams. The chassis for motor-driving tricycles is characterized in that the main beams are made of rectangular steel tubes, each of the centers is provided with a smooth bending, and the shapes of the side surfaces are caused to be similar to an arc tangent curve-shaped so as to form a space frame structure. The factors of longitudinal fracture of the chassis are eliminated. The chassis for motor-driving tricycles has the advantages of high strength, good installation performance, and more than one time increase of the bearing capacity.

Description

The motor tricycles chassis

The utility model relates to automotive frame's technical field of being made up of the frame member of vertical and horizontal layout.

The motor tricycles chassis, need to satisfy bear cut out lotus, run at high speed, uneven road surface jolts, instantaneous stamping power and travel in the requirement of multinomial performances such as rollover power, be one of most important assembly parts of three wheeled motor car.Existing motor tricycles chassis mostly adopts plane framework formula structure, and promptly girder and crossbeam are in the same plane.This chassis weak link is many, torque resistant and the anti-poor performance of jolting, and the processing technology complexity, the whole workpiece distortion is big, occurs problems such as fracture, bending easily, influences safe in utilization.

The motor tricycles chassis that the purpose of this utility model is a kind of intensity height of design, bearing capacity is big, safety performance is good.

For achieving the above object, the utility model by the following technical solutions: whole three-wheel vehicle chassis is made of girder longitudinally and many crossbeams being fixed on the girder.Its constructional feature be two longitudinally girder make by rectangular steel pipe, there is a level and smooth bending that makes progress at the middle part of girder, make the latter half of girder be higher than first half, and latter half is parallel with first half, thereby makes whole chassis form a space frame structure.

The utility model has the advantages that: removed the longitudinal fracture factor on chassis fully by the girder that has bending that rectangular steel pipe is made, the intensity height, safety performance is good, null solution quantity is few, manufacture craft is simple, and under the situation that overall weight does not increase, bearing capacity can be enhanced about more than once.

Below in conjunction with accompanying drawing the utility model is further described.

Fig. 1 is a front view of the present utility model;

Fig. 2 is the birds-eye view of Fig. 1,

Fig. 3 is the left view of Fig. 1.

In the embodiment that accompanying drawing provides, two longitudinally girder (3) make by rectangular steel pipe, there is a level and smooth bending that makes progress at the middle part, making its side view is the arc tangent curvilinear figure, before, during and after 7 crossbeams (2) (4) (5) (6) (7) (8) (9) divide and upper, middle and lower and Main Girder Welding are one, form an oblong space framework, the rear portion of framework is higher than anterior parallel.Vertical beam assembly parts such as (1) weld or are installed on the framework, form novel motor tricycles chassis.

Claims (1)

1. A kind of motor tricycles chassis, constitute by girder longitudinally and many crossbeams being fixed on the girder, it is characterized in that: two longitudinally girder (3) make by rectangular steel pipe, there is a level and smooth bending that makes progress at the middle part of girder (3), make the latter half of girder (3) be higher than first half, and latter half is parallel with first half.
