Abstract

The utility model provides a novel gear selecting and shifting speed-changing operation mechanism for a vehicle, which realizes the purpose of gear selecting and shifting speed changing by using a self-lubrication radial joint bearing as a moving member. The novel gear selecting and shifting speed-changing operation mechanism has the technical scheme that an inner hole of the self-lubrication radial joint bearing is connected with a shaft in clearance fit, both ends of the shaft are fixed on a fixed seat, and an outer ring of the self-lubrication radial joint bearing is fixed in a bearing sleeve; an operating lever and a gear shifting swing arm are directly and fixedly connected with the bearing sleeve; and a gear selecting swing arm is supported on the side surface of the fixed seat through a gear selecting swing arm shaft, one end of the gear selecting swing arm is fixedly provided with a lining with an inner spherical surface, a swing rod is fixed in the side direction of the bearing sleeve, a ball joint of the swing rod is matched with the lining with the inner spherical surface, the gear selecting swing arm can swing around the gear selecting swing arm shaft through the swing rod fixed in the side direction of the bearing sleeve, and a return torsion spring of the gear selecting swing arm is arranged between the gear selecting swing arm and the gear selecting swing arm shaft. The novel gear selecting and shifting speed-changing operation mechanism has the characteristics of strong generality, reliable performance, long service life, is flexible and convenient to operate and the like.

Description

A kind of new automobile shifting selector gear

Technical field

The utility model relates to automobile shifting selector gear.

Background technique

The constantly progressive and development along with automotive industry, people require also more and more higher to the automobile variable speed manoeuvring performance.Present automobile shifting selector gear motive position is easy to wear, causes handling that smoothness is poor, structural failure or reliability reduce.

Summary of the invention

The utility model proposes a kind of new automobile shifting selector gear, with self-lubricating plain radial bearing as moving link to realize shifting speed change purpose, this mechanism has highly versatile, reliable performance, manoeuvrable makes things convenient for characteristics such as long service life.

For this reason, the technical solution of the utility model is: a kind of new automobile shifting selector gear, comprise self-lubricating plain radial bearing, fixed base, operating handle, block selecting swing arm, block selecting arm shaft, gearshift swing arm, it is characterized in that: the endoporus of self-lubricating plain radial bearing is connected with an axle interference fit, the two ends of axle are fixed on the fixed base, and the outer ring of self-lubricating plain radial bearing is fixed in the bearing housing; Operating handle and gearshift swing arm are directly fixedlyed connected with bearing housing; The block selecting swing arm is supported on the fixed base side by the block selecting arm shaft, block selecting swing arm one end is fixed with the lining of band inner ball surface, the bearing housing lateral fixation has fork, the bulb of fork cooperates with the lining of band inner ball surface, the block selecting swing arm can be provided with the return torsion spring of block selecting swing arm by the side fixed fork of bearing housing around the swing of block selecting arm shaft between block selecting swing arm and the block selecting arm shaft.

Beneficial effect: swung to realize the block selecting purpose by operating handle, the operating handle swing is to realize the gearshift purpose.The bearing housing that the plain radial bearing outer ring links is with it realized shift speed change together by the operating handle swing; The laterally disposed fork of bearing housing, fork swing by operating handle and drive the block selecting rocking arm and move up and down to realize the block selecting speed change.The block selecting returning device is set, to realize block selecting return function simultaneously on the block selecting arm shaft.It is big that this selector gear shifting is handled pivot angle, reaches 23 °～25 °, and motive position easily realizes dust sealing and band self-lubricating function, so reliable performance, manoeuvrable makes things convenient for advantages such as long service life.This mechanism can be contained in the inner shift speed change of realizing of operator cabin, also can be contained in the operator cabin bottom and realize shift speed change.This mechanism connects firmly suitable simultaneously the connection with the remote flexible axle of gearbox with remote ball-joint pull bar, can change the size of plain radial bearing and fixed base mounting hole distance and shifting swing arm geomery and mate different automobile types, be applicable to existing light-duty vehicle, in-between car and heavy-duty car.
