Abstract

The utility model relates to an engine support for a motorcycle. A sleeve pipe is fixed with a motorcycle frame through bolts; the sleeve pipe is welded with a support arm and a bracket; the length L[1] and the angle beta of the support arm can be correspondingly changed according to the connection point of a selected engine; the other end of the support arm is welded with suspenders, and the total length L[3] of the suspenders and the length L[2] between one end and a centerline can also be selected according to the different connection points of the suspended engine. The utility model is characterized in that when the engine model is replaced, the motorcycle frame does not need to be redesigned or the connection part of the engine does not need to be redesigned; the engine can be connected with the motorcycle frame just by changing some sizes of each component of the utility model.

Description

Engine support for motorcycle

The utility model relates to a kind of motor cycle engine hanger bracket.

At present, the hanging method of motor cycle engine is broadly divided into fixed type and detachable two kinds.The hitch point that the fixed type suspension is hung (Fig. 1, Fig. 2) its driving engine is connected with vehicle frame is non-dismountable, therefore, when a kind of vehicle frame hangs the driving engine of multiple model, when the relative Vehicle Frame Design benchmark of hitch point is inconsistent, then must be according to the model of pre-mounted engine designing car frame again.On the motor bike of some higher gears time, its driving engine is to be connected (as Fig. 3) by a vibration damping joint with the vehicle frame of motor bike.It can not adapt to the installation of multiple model driving engine equally, when the conversion engine type, still needs to redesign the vibration damping joint.

The purpose of this utility model is, is connected with motorbike frame with the hanger bracket of a kind of convertible angle and size, makes vehicle frame can hang the driving engine of multiple model, when the conversion engine type, need not to redesign frame of motorcycle and with the attaching parts of driving engine.

Technical solution of the present utility model is, an effective bolt of cover and frame of motorcycle are fixed, and connects support arm and support on the sleeve pipe, the length L of support arm ₁Can do corresponding change according to selected driving engine contact with angle beta.The other end of support arm welds another sleeve pipe, the total length L of sleeve pipe ₃Length L with an end distance line of centers ₂Also can be selected according to the difference of the driving engine weld nugget that is hung.

The utlity model has when the re-engining model, need not redesign the advantage of frame of motorcycle or redesign driving engine attaching parts, when the conversion engine type, only need change a little some size of each parts of the present utility model and can be connected with the vehicle frame of motor bike, thereby simplified production control, reduced productive costs.

The detachable vibration damping head of Fig. 2 scheme drawing;

Fig. 3 structural representation of the present utility model;

Fig. 4 is that the H of Fig. 3 is to scheme drawing.

The center of sleeve pipe 1 penetrates bolt 2, and the length of sleeve pipe 1 is limited by motorbike frame 8, is equipped with tight nut 7 itself and vehicle frame are fixed.The curved part support arm 3 of U template places between sleeve pipe 1 and the sleeve pipe 4 length L of support arm 3 ₁Hitch point by institute's mounted engine is selected, and the other end of support arm 3 and sleeve pipe 4 join, and the angle of the axle center of sleeve pipe 4 and sleeve pipe 1 is β, and the size at β angle is by the determining positions of mounted engine hitch point, and 4 of sleeve pipes obtain different positions thus, as: A ₁, A ₂, A ₃Deng.With the connection location of two other hitch point of driving engine then by the total length L of sleeve pipe 4 ₃And the length L 2 of vehicle frame symmetrical center line determines relatively.After treating that its each position is determined, with the contact point welding of support arm 3 with sleeve pipe 1 and sleeve pipe 4.Support 5 is used for connecting spacer 6 and is welded on the sleeve pipe 1, makes spacer 6 obtain the position that is connected with vehicle frame 8, and spacer 6 is used for limiting hanger bracket and rotates the play that reaches on X-axis around X-axis, and hanger bracket fastener 9 is fixed on the frame of motorcycle.

Be example only with MX50Q-4 type motor bike, hanger bracket β=202 of use °, L ₁=73.4mm, L ₂=27.9mm, L ₃=77.5mm.

Claims

1, a kind of motor cycle engine hanger bracket of being made up of sleeve pipe, support arm is characterized in that, it is L that support and length are arranged on the sleeve pipe that connects to ground ₁And can change the support arm of its angle, the length that the other end of support arm is connected to one end distance vehicle frame symmetrical center line is L ₂, total length is L ₃Another sleeve pipe, the angle between two sleeve pipes is β, the other end of support is connected to spacer and fixes with frame of motorcycle.
