Abstract

The invention discloses a manual gear shifting mechanism, and belongs to the technical field of engineering machinery. According to the manual gear shifting mechanism, the defects that a traditional manual gear shifting mechanism has complex structure, low reliability and poor maneuverability in the prior art are overcome. The main structure of the manual gear shifting mechanism comprises an upperplate, a front fish eyeball head, a rear fish eyeball head, a bracket, and a cross shaft assembly. The lower end of the upper plate is provided with an upper yoke, and a lower yoke is arranged on thebracket. The upper yoke is in transmission connection with the lower yoke through the cross shaft assembly. A front plank and a rear plank are further arranged on the upper plate. The front plank isconnected with the front fish eyeball head, and the rear plank is connected with the rear fish eyeball head. The manual gear shifting mechanism is mainly used for construction machinery.

Description

Technical field: [0001] The invention belongs to the technical field of engineering machinery, and in particular relates to a manual shift mechanism. Background technique: [0002] In construction machinery, the loader needs to work under different working conditions. In order to achieve forward, backward, and switching between different speeds, a gear shifting mechanism is required. At present, there are mainly three kinds of control on the gear position of the gearbox: 1. manual shift mechanism; 2. electric control handle shift mechanism; 3. automatic shift mechanism. At present, the first and second types are widely used, and with the development of electronic control technology, the third type is becoming more and more common. [0003] However, in the current domestic market, the manual shifting mechanism occupies more than 70% of the market share. The manual shifting mechanism is popular among domestic users for its reliability, durability, low cost, and easy maintenan...
