Abstract
The utility model relates to an engine bracket structure for motorcycles, which comprises a bracket with a left bracket pipe and a right bracket pipe, a beam pipe fixed at the bottom of the bracket for installing supports of rear pedals. The engine bracket structure is characterized in that connecting pipes are respectively welded at an end of the left bracket pipe and an end of the right bracket pipe, and each connecting pipe is perpendicular to the left bracket pipe or the right bracket pipe, and two end openings of the beam pipe are provided with internal screwed holes. The connecting pipe of the left bracket pipe and the connecting pipe of the right bracket pipe are respectively fixed at two ends of the beam pipe through a pair of bolts with threads. The engine bracket structure for motorcycles changes an installing position of the left bracket pipe and an installing portion of the right bracket pipe of the previous structure, thereby enabling installation of the bracket to have no interference with that of hanged bolts of the engine, accordingly the hanged bolts of the engine can be assembled directly through guns, labor intensity of workers can be lowered, and assembling efficiency can be enhanced.
Description
Technical field
The utility model relates to frame of motorcycle, relates in particular to the motorcycle engine bracket structure.
Background technology
Existing motorcycle engine bracket comprises carriage left side pipe and the right pipe of carriage, the end of carriage left side pipe and the right pipe of carriage is flats, the carriage left side tube end of this flats and the right tube end of carriage are provided with and are used for and bottom of frame bonded assembly mounting hole, are provided with the Hanging bolt that is used to hang the driving engine lower end at bottom of frame.The right tube end of carriage left side tube end and carriage is at the attachment point of close Hanging bolt of the attachment point of bottom of frame and bottom of frame.Also be provided with a crossbeam pipe at bottom of frame, the two ends of crossbeam pipe respectively connect a back foot support by bolt respectively, and the crossbeam pipe is away from the attachment point of Hanging bolt and bottom of frame, the installation mutually noninterfere that is installed on Hanging bolt of back foot support.Existing motorcycle engine bracket structure, during online assembling, no matter engine holding frame is adorned still back dress earlier, because the right tube end of carriage left side tube end and carriage is at the attachment point of close Hanging bolt of the attachment point of bottom of frame and bottom of frame, therefore the Hanging bolt of driving engine all is subjected to the influence of carriage left side pipe and right pipe, make Hanging bolt to assemble, must adopt the manual type assembling, have a strong impact on efficiency of assembling with rifle.
The utility model content
The technical matters that the utility model solves is: a kind of motorcycle engine bracket structure is provided, the installation mutually noninterfere of the installation of engine suspension bolt and carriage, can be directly with the Hanging bolt of rifle assembling driving engine, and the attachment point position of pedal frame after changing not.
The technical solution of the utility model is: a kind of motorcycle engine bracket structure, comprise carriage, be fixed on the crossbeam pipe that bottom of frame is used to install the back foot support with carriage left side pipe and carriage right side pipe, it is characterized in that, the end of described carriage left side pipe and the end of the right pipe of carriage respectively are welded with one section connection pipe, connection pipe is vertical with the right pipe of carriage with carriage left side pipe respectively separately, the two-port of described crossbeam pipe all is made as internal thread hole, and the connection pipe of carriage left side pipe and the connection pipe of the right pipe of carriage respectively are fixed on the two ends of described crossbeam pipe by a pair of screw bolt.
The afterbody of each pair screw bolt is equipped with outside thread, and the head of each pair screw bolt is equipped with internal thread hole; The afterbody of described pair of screw bolt passes described connection pipe and screws in the internal thread hole of described crossbeam pipe.
Described pair of threaded bolt heads has the back foot support by bolted connection.
The beneficial effects of the utility model are:
1, because the end of the end of carriage left side pipe and the right pipe of carriage respectively is welded with one section connection pipe, the connection pipe of carriage left side pipe and the connection pipe of the right pipe of carriage respectively are fixed on the two ends of described crossbeam pipe by a pair of screw bolt, changed the installation site of carriage left side pipe and carriage right side pipe in the original structure, make the installation of carriage and the installation mutually noninterfere of engine suspension bolt, therefore can directly assemble the Hanging bolt of driving engine with rifle, alleviate labor strength, improve efficiency of assembling.
2, because the afterbody of two screw bolts is provided with outside thread, the head of two screw bolts is provided with internal thread hole, two threaded bolt heads have the back foot support by bolted connection, therefore though carriage is connected the two ends of crossbeam pipe in this structure, but the back foot support still continues to be installed in the two ends of crossbeam pipe, it is simple in structure, need not to increase in addition improvement cost.
Description of drawings
Fig. 1 is a mounting structure scheme drawing of the present utility model;
Fig. 2 is a mounting structure scheme drawing of the present utility model;
Fig. 3 is the P place enlarged diagram of Fig. 2;
Fig. 4 is the structural representation of two screw bolts in the utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
Referring to Fig. 1～Fig. 4, a kind of motorcycle engine bracket structure, comprise carriage 1 with carriage left side pipe 1a and the right pipe of carriage 1b, be fixed on bottom of frame and be used to install the crossbeam pipe 2 of back foot support, the end of carriage left side pipe 1a is welded with one section connection pipe 3a, the end of the right pipe of carriage 1b is welded with one section connection pipe 3b, connection pipe 3a is vertical with carriage left side pipe 1a 1b, connection pipe 3b is vertical with the right pipe of carriage 1b, the two-port of crossbeam pipe 2 all is made as internal thread hole, and the connection pipe 3a of carriage left side pipe and the connection pipe 3b of the right pipe of carriage respectively are fixed on the two ends of crossbeam pipe 2 by a pair of screw bolt 4.The afterbody of each pair screw bolt 4 is equipped with outside thread 4a, and the head of each pair screw bolt 4 is equipped with internal thread hole 4b; The afterbody of two screw bolts passes connection pipe and screws in the internal thread hole of crossbeam pipe 2.Two threaded bolt heads 4b have the back foot support by bolted connection.The Hanging bolt 6 of driving engine 5 bottoms and the attachment point mutually noninterfere that is positioned at the carriage at crossbeam pipe 2 two ends can alleviate labor strength directly with the Hanging bolt 6 of rifle assembling driving engine, improve efficiency of assembling.
