Abstract
The utility model discloses a child Mtx mototrax frame, comprising a vertical pipe, a girder of the frame and a rear end frame, wherein, the whole of the girder of the frame is pressed by single pipe; the welded place of the girder of the frame and the vertical pipe is provided with a reinforcing rib; the rear end frame is made of a solid pipe and is fixed on the girder of the frame by a bolt; the girder of the frame is provided with a left hanger and a right hanger of an engine; the girder of the frame is provided with a lower bracket, a fixed position for the engine is formed between the girder of the frame and the lower bracket. The fixed position for the engine of the utility model adopts three positions to be fixed and adds a fixed position for the lower bracket compared with the prior frame to support the engine and a foot rack, thereby preventing the engine and the foot rack from falling down in the process of the child Mtx mototrax flying and jumping; moreover, the utility model has simple structure and convenient installation and can bear the weight of the engine and reduce the vibration.
Description
Technical field
The utility model is a kind of motorcycle accessories, particularly relates to a kind of Xiao Tong cross-country motorcycle vehicle frame.
Background technology
Xiao Tong cross-country car vehicle frame on the market is the installation basis of car load parts now, and it forms one integral body with organic gangs such as driving engine, driving system, suspension gear, steering hardware, wheels.Vehicle frame not only will bear driving engine, each part assembly and people's quality, impact and vibrations but also will bear from ground-surface, pitch in the process of moving, people's weight all concentrates on the back afterbody of vehicle frame, impulsive force is very big, afterbody support tube or vehicle frame are fractureed, the shock effect that is caused is on vehicle frame, influence to vehicle performance is very big, and can pass to chaufeur, greatly reduce comfort, so vehicle frame must possess enough intensity and bending resistance, antitorque ability, also should alleviate own wt as much as possible simultaneously, to improve its dynamic property and economy.Several problems below the present vehicle frame ubiquity that uses on the Xiao Tong cross-country car: 1, the low-carbon alloy structural steel that the vehicle frame main beam working strength is not high (20CrMo) material, it generally is the structural alloy steel (CrMo) that adopts 2.54cm, two pipes also are welded on the standpipe, two-tube centre adds reinforced rib, needs the many places welding, is connected with main body of vehicle frame by a large amount of screw bolt and nut again, the waste materials, set-up time is longer, reduce intensity in the use greatly, and vehicle frame is laid particular stress on.2, the driving engine fixed bit is only fixed with two bolts, can not firm well driving engine.
The utility model content
The utility model is to overcome the deficiencies in the prior art, provide a kind of can guarantee frame strength, stationary engine, minimizing vibrations Xiao Tong cross-country motorcycle vehicle frame.
A kind of Xiao Tong cross-country motorcycle of the utility model vehicle frame, finish by following technical scheme:
A kind of Xiao Tong cross-country motorcycle vehicle frame has comprised standpipe, vehicle frame main beam, back tailstock, and the integral body of described vehicle frame main beam is by the single tube press forming; Described vehicle frame main beam and standpipe weld are provided with a reinforced rib; Described back tailstock is made by solid tubes, and back tailstock adopts and is bolted on the vehicle frame; Described vehicle frame main beam is provided with the left and right hangers of driving engine; Described vehicle frame main beam is provided with bottom bracket, forms a driving engine fixed position between vehicle frame main beam and the bottom bracket.
It is to be divided into two by hangers that the left and right hangers of described driving engine adopts detachable structure, last slice be welded on the vehicle frame main beam, following sheet and last slice adopt bolt.
The fixed position of described driving engine adopts fixedly be by hangers stationary engine top at 3, and bottom bracket is held the weight of driving engine, and is fixed at midway location by vehicle frame main beam.
Above-described bottom bracket is provided with the groove that can hold stationary engine.
Described vehicle frame main beam is to use the single tube of 5.08cm medium carbon structural alloy steel (30CrMo).
Described back tailstock is the square solid tubes, and back tailstock is Y-shaped, and back tailstock and vehicle frame main beam welding back are triangular in shape.
Described reinforced rib is semi-circular pipe.
The left side that described vehicle frame main beam is provided with; right hangers; left and right sides hangers adopts detachable structure; described vehicle frame main beam is provided with bottom bracket; driving engine is installed for convenience; hangers is divided into two; last slice be welded on the vehicle frame main beam; following sheet and last slice adopt bolt; like this connection mode with on girder, punch; directly the single piece type hangers is fixed on above the girder and compares with bolt; can avoid on girder, punching; minimizing is to the influence of main beam structure intensity, and the driving engine fixed bit adopts three stationkeeping, increases the bottom bracket fixed bit than general vehicle frame; hold driving engine and leg rest frame, can protect driving engine better; the leg rest frame can not drop out in Xiao Tong cross-country car flyer process.
Described vehicle frame main beam is to use the single tube of 5.08cm.Described reinforced rib is semi-circular pipe.Vehicle frame main beam uses the mono-tube design of 5.08cm, and material adopts medium carbon structural alloy steel (30CrMo), medium carbon structural alloy steel (30CrMo) strength of material height.Girder adopts the 5.08cm single tube, and two 2.45cm pipes are light than using, owing to adopt single tube, welding is local to be reduced, and monoenergetic does not make vehicle frame attractive in appearance, but also guarantees the intensity of vehicle frame.Standpipe and Main Girder Welding place also add a semi-circular pipe reinforced rib, strengthen intensity herein.Back tailstock uses import aluminum alloy aluminium sheet 6061 materials, adopts to be bolted on the vehicle frame, and back tailstock is the square solid tubes, compares use alloy structureal steel (CrMo) pipe, also makes the weight can be not overweight in the requirement of proof strength.Adopt such scheme, simple in structure, easy for installation, but vehicle frame bears the weight of driving engine, reduces vibrations.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a block diagram of the present utility model.
The specific embodiment
Below in conjunction with the accompanying drawing further instruction, as shown in the figure, a kind of Xiao Tong cross-country motorcycle vehicle frame has comprised standpipe 2, vehicle frame main beam 1, back tailstock 3, and the integral body of vehicle frame main beam 1 is to use the single tube of 5.08cm, by the single tube press forming; Vehicle frame main beam 1 and standpipe 2 welds are provided with the reinforced rib 12 of a semi-circular pipe; Back tailstock 3 is the square solid tubes, and back tailstock is the square solid tubes, and back tailstock is Y-shaped, and back tailstock and vehicle frame main beam welding back are triangular in shape.Back tailstock 3 adopts and is bolted on the vehicle frame main beam 1; Vehicle frame main beam 1 is provided with the left and right hangers 13 of driving engine; Vehicle frame main beam 1 is provided with bottom bracket 11, forms a driving engine fixed position between vehicle frame main beam 1 and the bottom bracket 11.It is to be divided into two by hangers that the left and right hangers of driving engine 13 adopts detachable structure, last slice 131 be welded on the vehicle frame main beam, following sheet 132 131 adopts bolt with last slice.The fixed position of driving engine adopts fixedly be by above hangers 13 stationary engines at 3, and bottom bracket 11 is held the weight of driving engine, and is fixed at midway location by vehicle frame main beam 1.Bottom bracket 11 is provided with the groove 112 that can hold stationary engine.
