Abstract

PURPOSE:To enable to set a large gear ratio in an emergency low speed stage by a method wherein rotation is transmitted from an idler shaft in a reverse stage through an intermediate shaft, which serves for both the reduction of speed and the change of rotational direction, to a countershaft in order to sequentially reduce the rotational speed. CONSTITUTION:An idler gear shaft 23 is rotated in its speed-reduced state through a drive gear 20a in a reverse stage and an idler gear 20b by means of the power inputted to a main shaft 11''. An intermediate gear shaft 27 is further rotated in its speed-reduced state through the drive gear 26a of the idler gear shaft 23 and a driven gear 26b. The rotation of the intermediate gear shaft 27 is furthermore reduced through the drive gear 26c of the intermediate gear shaft 27 and a driven gear 26d, which is made into an integral body with the countershaft 12 by means of a synchronizing mechanism in order to obtain the emergency low speed stage. In such speed changes in three stages as mentioned above, the setting of a larger gear ratio becomes possible.

Description

[Detailed description of the invention] The present invention can be used, for example, in a one-wheel drive vehicle.

Regarding the transmission of a vehicle that is capable of rough 1-speed driving, etc., it is particularly important to shift from 1st gear to 1-magical gear ratio (hereinafter abbreviated as LL). The gear is 2-shaft normal 11. similar to the previous) IL speed a gear. It opens even though it is assembled with a joint type structure.

A 4-wheel drive vehicle has a lower I\C'1. compared to a 2-wheel drive vehicle. I17 Grizupka has increased to 19 in pitching and rough road running ability.
Therefore, in order to fully utilize this performance, the 1st to 4th forward gears are set to the 1st gear (L gear with a large ratio of 7). In addition, this [Improve the driving ability on steep slopes etc. using the EL gear stage] has already been achieved! The applicant has proposed J.S.1j11.

Here, the gearbox C, which has 4 forward gears and 1 reverse gear, has a shift position opposite to S and J in reverse gear, and when the In2 is output from rough [1-mode], it alternates between forward and reverse gears. I have something to say, i! Anti-slip in the same luff j-1j direction as the second transition stage 111
It is desirable that there be a 1-speed gear in 11.Also, in terms of production and compatibility with other car models, it is desirable to have a gear mechanism that obtains the normal 1st to 4th gears separately. It is desirable to install a gear mechanism for gears, and for this reason, J:
Su1I resignation 1! The Yamanaka mechanism, which is responsible for the synchronization force that selects one of the gears A7 and A of the round 7 group and IEL gear, is the same as the Yamanaka mechanism of the forward speeds of 1st to 11th speeds.
There are 114 of them each in constant meshing type.

By the way, it is composed of a two-shaft, constantly meshing type [1st gear gear j72! For J3 in Y, the distance between the I:L drive gear A7 on the main shaft side and the L driven gear on the subshaft side is determined by d3, and in order to increase the gear ratio, it is 13! - Trizogi 1) 1X17 + Decrease the number.” Also there is (
Yu limit vl! Therefore, [1-Gear gear!] There is a problem in that there are restrictions on setting a large ratio, and it becomes impossible to obtain a gear ratio higher than that.

Therefore, in order to easily set the gear 7 ratio of the 1st gear, it is necessary to decelerate only one gear using the 1:1 drive and driven gear of the upper gear. Deceleration V\7 for deceleration is performed in multiple stages with different lu (T is enough.

In this case, [Shi, gear ψ group of the gear stage (YoSame 11
Since the rear 50 gear V group is arranged adjacent to the 111 gear, the idler gear of this 19 il gear group is used, and the gear which also functions for deceleration and rotation direction conversion (=
No need to add J and perform 3-stage deceleration 1) 41,
As a prior art related to this point, for example, Japanese Patent Application Laid-Open No. 56-90
15 (There is a problem in Publication No. 8.

However, in the above-mentioned publication r 4J, there is an intermediate gear (7) which dispatches its help to the main 11C and takes out C, and ``this gear (
3. The idler gear A7 and the second stage deceleration gear puller are placed on the 7th axis, and the idler gear 17 is not used for deceleration. J: Since the gear X, which also functions as a gear reducer and converts the direction of rotation, meshes with the gear A7 for reduction of the gear shaft connected to -, it is supported independently and arranged in C, so it becomes multi-phase in a 411 yen structure. , 6 extra spaces are required. Furthermore, that Gi17
Since it directly meshes with the secondary shaft 4゛A7, it is possible to reduce the speed and change the direction of rotation (the second stage before and after the 7)
The selection of gear A7 ratio for the second stage lacks precision.

The present invention was made in view of the circumstances,
For the 1st to 4th gear gear mechanisms, the gears for reverse gear and [L change gear] gears are each equipped with a two-shaft, constantly meshing type. Idler gear drive with drive gear A7 and idler gear - IA7 or 13 deceleration and rotation φl - direction change 1a
