Abstract

The invention provides a transmission double-lever control device assembly. A transverse gear shifting lever is provided with a switch control block, a self-locking control block and a gear shifting block, the switch control block, the self-locking control block and the gear shifting block rotate synchronously with the transverse gear shifting lever, and a shell is provided with a self-locking assembly and a reverse gear lock assembly. A groove is formed in the self-locking control block in the circumferential direction, and when the self-locking assembly is located in the groove, neutral gearpositioning is carried out on the gear shifting block. The circumferential surface of the gear shifting block is provided with a protrusion, the gear shifting block slides horizontally, and when gearshifting forth increases and the reverse gear lock assembly reaches the top of the protrusion, a reverse gear position is selected into. According to the transmission double-lever control device assembly, self-locking and reverse gear locks are arranged on the control assembly, all the gears share the self-locking assembly, the consistency of gear shifting force is guaranteed, meanwhile the gearshifting force can be debugged without disassembling a gearbox, the number of parts is reduced, the cost is reduced, and the transmission double-lever control device assembly has high use value and promotion value.

Description

technical field

[0001] The invention relates to the field of gearboxes of motor vehicles, in particular to an assembly of a double-rod operating device for a gearbox. Background technique

[0002] As the main part of the automobile transmission system, the transmission should not only realize the function of variable speed and torque, but also prevent the transmission from automatically shifting and disengaging. It cannot be engaged in two gears at the same time. lock function.

[0003] In order to prevent reverse gear from being mistakenly engaged, there is also a reverse gear lock function. The high and low gear conversion of the transmission auxiliary box synchronizer of the main and auxiliary box structure must be carried out when the main box is in neutral, and the main and auxiliary box interlock function is also required. Single H-operated transmissions usually arrange self-locking, interlocking, reverse gear lock, and main and auxiliary box interlocking mechanisms i...

Examples

Embodiment 1

[0045] The working principle of a transmission double-lever operating device assembly provided by the present invention in forward gear will be described in detail below.

[0046] First, the gear selection operation is performed, and the gear selection shaft assembly 15 drives the shift dial 5 to move axially to the forward gear selection position; at this time, the shift dial 5 is in the neutral position, and the self-locking pin 8 is in the self-locking position. In the groove of the first boss on the control block 4, the neutral gear is positioned; the ejector rod of the air circuit control valve 6 and the ejector rod of the neutral gear indicator switch 7 are located in the corresponding V-shaped groove on the switch control block 3, and the air Road control valve 6 and neutral indicator switch 7 are both in open state; the handle pin 18 of the reverse gear lock assembly is in contact with the circumferential surface of the shift knob 5, and the reverse gear indicator switc...
