Abstract

The invention provides a stiff pole shift system which comprises a shift control assembly and a shift draw bar assembly, wherein the shift draw bar assembly is divided into a front shift draw rod and a rear shift draw rod which are connected through a damping device. The damping device comprises a sliding block sleeve installed at the end part of the front shift draw rod and a sliding block installed at the end part of the rear shift draw rod, and the sliding block is inserted into the sliding block sleeve and matched with the sliding block sleeve in a sliding manner. A bush is arranged at the bottom of the sliding block sleeve, and the bottom of the sliding block sleeve is clamped at the inserting end of the sliding block through a damping spring. A dust cover is sheathed outside of the damping device, one end of the dust cover is clamped on the sliding block sleeve through a snap spring, and the other end of the dust cover is clamped at the end part of the rear shift draw rod through the snap spring. The stiff pole shift system damps the vibration suffered through the damping device, so that the out-of-gear times of a gearbox are greatly reduced in the vehicle running process, and the driving comfort and reliability is increased. An unlock mechanism can conveniently release the locking device of a telescopic rod assembly. The structure is simple, safe and stable.

Description

technical field

[0001] The invention belongs to the field of heavy trucks and relates to a shift system, in particular to a hard rod shift system. Background technique

[0002] Heavy-duty trucks currently widely use the hard lever shift system, which has the advantages of light operation, long service life, low maintenance cost, and clear shift selection. However, the shift control device of this system is arranged on the floor of the driver's cab, and the driver's cab is connected to the vehicle frame through a suspension, so that the driver's cab will move relative to the vehicle frame during driving. When driving on a road with poor road conditions, the shift lever may vibrate severely or even shift out of gear, which will seriously affect the driving comfort and reliability of the vehicle. Contents of the invention

[0003] The invention provides a hard lever gear shifting system, the purpose of which is to reduce the vibration received by it, and greatly reduce the n...

Embodiment Construction

[0017] The specific implementation of the present invention will be described in further detail below by describing the embodiments with reference to the accompanying drawings, so as to help those skilled in the art have a more complete, accurate and in-depth understanding of the inventive concepts and technical solutions of the present invention.

[0018] Such as Figure 1 to Figure 3 As shown, the present invention provides a hard rod shift system, including a shift manipulation assembly 1 and a shift rod assembly 3 . The shift rod assembly 3 is divided into a front gear shift rod 7 and a rear gear shift rod 12, and the front gear shift rod 7 and the rear gear shift rod 12 are connected by a buffer device 4. The buffer device 4 can absorb the impact of the shift rod assembly 3 during driving, reducing the probability of the transmission being out of gear.

[0019] The buffer device 4 includes a slider sleeve 8 installed at the end of the front gear shift rod 7 and a slider ...
