a gear shifter

Abstract

The invention relates to a gear shifting manipulator. The gear shifting manipulator comprises a manipulator support, a gear-shifting limit block, a limit bolt, a gear shifting shaft, a gear-shifting rocker arm and a shift-selecting rocker arm, wherein the gear-shifting limit block is movably mounted at the top end of the manipulator support, and consists of a transverse limit part and a longitudinal limit shaft; the gear-shifting rocker arm comprises a basis part and a connecting arm; a gear lever is arranged at the top end of the basis part in a penetrating manner; a bolt clamping groove is formed in the connection position of the basis part and the connecting arm; the limit bolt is provided with a cylindrical cavity, and the other end of the limit bolt is in contact connection with a neutral limit groove in a movable manner; a spring is embedded in the cylindrical cavity; one or more pairs of anti-rotation blocks are arranged on the limit bolt; the gear-shifting limit block collides with a gear-shifting limit blocking pad during forward shifting and backward shifting; one side of the upper end of the shift-selecting rocker arm is connected with a shaft body at one end of the gear shifting shaft in an assembled manner, and a rotating shaft of the gear-selecting rocker arm is fixedly arranged on the other side of the upper end of the shift-selecting rocker arm. The gear shifting manipulator disclosed by the invention has the advantages that the structural design is reasonable, the operation and the use are simple, the feeling of manipulation is good, gear selection and shifting are convenient and reliable, the out-of-gear problem after engagement of gears can be effectively avoided.

Description

technical field [0001] The invention belongs to the technical field of auto parts, and relates to a gear shift manipulator, in particular to a gear shift manipulator with a limit device that can effectively avoid problems such as disengagement of gears and failure to find a neutral gear after gears are engaged. Background technique [0002] Manual gear shift manipulators are generally not designed with shift manipulators. In actual use, manual gear shift manipulators, especially truck manual gear shift manipulators, often lose gear due to vehicle bumps and other reasons; It is difficult to find the neutral position due to the gear limit device. When changing gears, you need to shake the gear lever repeatedly to find the feeling and then change gears. The control feeling is very bad. [0003] The manual gear shift manipulator shakes the shift rocker arm left and right when selecting gears, and the gear selection rocker arm rotates around the gear selection rocker shaft throug...

AI Technical Summary

Problems solved by technology

Although this invention can also realize the gear shift limit operation, the locking area has an integrated casting structure and is a spherical structure. This structural design is easy to make the locking element stuck on the side of the locking area after shifting and cannot be effectively returned. , at the same time, because the locking element has a certain deflection angle with the shift arm during the gear selection process, and the casting structure of the locking area cannot match the deflection with the shift arm. This deflection angle cannot be effectively transitioned. During the rotation process Unexpected wear will be caused to the locking area and locking elements; at the same time, when the manipulator is shifted back to neutral, the locking elements will not return to normal in time, and they will be stuck on the limit groove so that the neutral position cannot be found. Improved shift efficiency and shift feel
