Embodiment Construction

[0032] I to V gears are sequentially arranged on the driven shaft 1, and the I gear driven gear 7 is installed on the hydraulic clutch, and the hydraulic clutch and the driven shaft are connected by the spline 4 and the spline groove 2; the ratchet 19 is placed in a semi-concave In the groove part 16, the ratchet end arm 10 is fixed on the ratchet wheel 19 through threaded connection, and the assembled semi-groove part 16 is interference-fitted into the special-shaped hole 14; II to V gear driven teeth 8 pass through the bearing 9 and The driven shaft 1 is connected, and the bearing 9 is an interference fit with the driven shaft 1. The cylindrical head 11 slides into the driven shaft 1, the fixed sleeve 12 is sleeved on the outside of the pull rod 13, and then the convex arm 25 is embedded in the square groove 15 to keep the pull rod from rotating.

[0033] Under normal conditions, the ratchet 17 falls in the half groove part 16, as Figure 13 , 14 As shown, it is in neutral...

Abstract

The invention relates to a mechanical type pull rod shift transmission. Driven gears from gear I to gear V are arranged on a driven shaft in sequence; a hydraulic clutch is arranged in the gear I (reverse gear); the driven shaft corresponding to the positions of the driven gears from gear II to gear V is a hollow plain shaft; two axisymmetric profiled holes in 180 degrees are opened on the position where the driven shaft is contacted with a ratchet wheel; profiled holes between adjacent driven gears are arranged in a staggered way in 90 degrees; a cylindrical head of the pull rod slips into the hollow plain shaft of the driven gear. The transmission finishes shifting action from gear I to gear V by the linear motion of the pull rod, therefore, the shifting is not only high in accuracy and short in time but also small in shifting force and easy in automobile start (gear I or reverse gear). The transmission has simple structure, high efficiency and small volume and is suitable for vehicles with mechanical type manual transmission, in particular suitable for vehicles with narrow space.

Description

Technical field [0001] The invention relates to a transmission for automobiles, in particular to a mechanical pull-rod shift transmission. Background technique [0002] At present, there are two main categories of automotive transmissions, one is automatic transmissions, which are mostly composed of hydraulic torque converters, clutches as auxiliary components, planetary gear trains, and complex control systems. However, there are inevitably certain disadvantages at the same time, such as: large fuel consumption, complex mechanism, difficult manufacturing, heavy weight, and unsuitable maintenance. Moreover, its complex manufacturing process has affected the development of the automobile industry to a certain extent. The other is a mechanical manual transmission. Because the shifting device of this transmission is heavy, it is mostly hydraulically driven. The hydraulic drive has high requirements for components, its cost is high, and it requires a large layout space. Especia...
