Abstract

The utility model relates to a frame of motorcycles or tricycles, which aims to resolve the problem of incapability of bearing large-volume engines in the prior art and the like. The frame comprises a main tube and a main beam connected with an approximately upper end of the main tube. Two inverted L-shaped suspension brackets are arranged at the middle lower portion of the main tube towards the rear side of the cycle. Cross beams are connected between the middle section and the rear portion of the two suspension brackets. The rear portions of the suspension brackets on both sides of the main beam are provided with Y-shaped supports facing upward, the front upper end of the support is connected to the middle portion of the main beam, and the rear upper end of the support is located on both sides of the middle rear side of the main beam. The frame further comprises horizontal support bars disposed on both sides of the main beam, one end of the support bar is connected to the middle portion of the main beam and the other end extends toward the rear of the main beam, and the middle portion of the support bar is connected with the rear upper end of the support. The cross beam at the tail portion of the suspension bracket is provided with a connecting shaft sleeve. By utilizing the structure, the engine can be installed between the left L-shaped suspension bracket and the right L-shaped suspending bracket, and the utility model allows large volume of the engine, because the two L-shaped suspension are used to bear the engine.

Description

Two take turns, the motor tricycle vehicle carriage

Technical field

The utility model relate to a kind of two take turns, the motor tricycle vehicle carriage.

Background technology

Existing two take turns or the motor tricycle vehicle carriage all similar substantially to bicycle rack, driving engine is suspended on cant beam below, its place ahead by bolt, this structure causes the volume of driving engine can not be too big, high-power two is taken turns, motor-tricycle thereby can not make; And existing two take turns with motor tricycle vehicle carriage and trailing wheel on the back flat frame installed all are one design-calculateds, like this, two-wheeled motorcycle can only use as two-wheeled motorcycle, motor-tricycle can only use as motor-tricycle, for the family that needs two kinds of motor bikes simultaneously, just need to buy two kinds of motor bikes, cause bigger waste.

The utility model content

For overcoming above-mentioned defective, the purpose of this utility model be to provide a kind of simple in structure, can carry that two of large volume driving engine is taken turns, the motor tricycle vehicle carriage.

For achieving the above object, the utility model two is taken turns, the motor tricycle vehicle carriage, comprise be responsible for and with the girder of being responsible for nearly upper end position bonded assembly, described girder extends to rear view of vehicle from being responsible for; Be provided with two in the position of being responsible for the middle and lower part to rear view of vehicle and fall L shaped hanger bracket, two hanger brackets are opened from being responsible for to expand to the left and right sides, girder below; Be connected with crossbeam between the stage casing of two hanger brackets and the afterbody; Hanger bracket afterbody in described girder both sides upwards is provided with Y font bracing frame, and the preceding upper end of bracing frame is connected the middle part of girder, and the back upper end of bracing frame is arranged in the both sides at girder rear; Also comprise the horizontal support bar that the girder both sides are set, the one end is connected the girder middle part, and the other end extends behind girder, and its middle part is connected with the back upper end of bracing frame; On the crossbeam of hanger bracket afterbody, be provided with connecting bushing.

Further, also comprise with the suitable three-wheel vehicle of described axle sleeve after flat frame, behind the described three-wheel vehicle flat frame front end be provided with at least one with the suitable axle sleeve of hanger bracket afterbody connecting bushing.

Further, also comprise with the suitable cart of described axle sleeve after flat frame, behind the described cart flat frame front end be provided with at least one with the suitable axle sleeve of hanger bracket afterbody connecting bushing.

Adopt said structure, be positioned at the L shaped hanger bracket and integrally formed encircling type vehicle frames such as crossbeam and Y shape bracing frame of the left and right sides, girder front lower place, like this, can be between the L shaped hanger bracket of two left and right sides with engine installation, and, then allow the volume of driving engine bigger owing to carry driving engine by two L shaped hanger brackets; And the crossbeam that is located at the hanger bracket afterbody is provided with connecting bushing, can install and change the back flat frame of trailing wheel by bearing pin easily, thereby more easily realizes the conversion of two-wheeled motorcycle and motor-tricycle.

Description of drawings

Fig. 1 takes turns for the utility model two, the structural representation of motor tricycle vehicle carriage.

Fig. 2 is the structural representation of flat frame behind the three-wheel vehicle.

The specific embodiment

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

To shown in Figure 2, the utility model two is taken turns, the motor tricycle vehicle carriage as Fig. 1, comprise be responsible for 1 and with the girder 2 of being responsible for nearly upper end position bonded assembly, described girder extends to rear view of vehicle from being responsible for; Be provided with two in the position of being responsible for 1 middle and lower part to rear view of vehicle and fall 3, two hanger brackets 3 of L shaped hanger bracket and expand to the left and right sides, girder below and to open from being responsible for 1, the outside of two hanger brackets is provided with stretcher 31; Be connected with crossbeam 4 between the stage casing of two hanger brackets 3 and the afterbody; Hanger bracket afterbody in described girder 2 both sides upwards is provided with Y font bracing frame 5, and the preceding upper end of bracing frame is connected the middle part of girder, and the back upper end of bracing frame is arranged in the both sides at girder rear; Also comprise the horizontal support bar 6 that the girder both sides are set, the one end is connected the girder middle part, and the other end extends behind girder, and its middle part is connected with the back upper end of bracing frame; On the crossbeam of hanger bracket afterbody, be provided with connecting bushing 7.

For the ease of installing and change the back flat frame of cart and three-wheel vehicle, only need to get final product at the suitable axle sleeve 8 of flat frame the place ahead setting thereafter and hanger bracket afterbody connecting bushing.

In sum, be positioned at the L shaped hanger bracket and integrally formed encircling type vehicle frames such as crossbeam and Y shape bracing frame of the left and right sides, girder front lower place, like this, can be between the L shaped hanger bracket of two left and right sides with engine installation, and, then allow the volume of driving engine bigger owing to carry driving engine by two L shaped hanger brackets; And the crossbeam that is located at the hanger bracket afterbody is provided with connecting bushing, can install and change the back flat frame of trailing wheel by bearing pin easily, thereby more easily realizes the conversion of two-wheeled motorcycle and motor-tricycle.
