装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a spare tire hoisting device for a vehicle such as an automobile, and more particularly to a spare tire hoisting device having a differential gear.
従来より、差動歯車機構を用いたスペアタイヤ巻き上げ
装置は広く使用されている。Conventionally, spare tire hoisting devices using differential gear mechanisms have been widely used.
しかし、このスペアタイヤ巻き上げ装置の差動歯車機構
は該差動歯車機構そのものに巻き上げた状態で保持する
機能を有しているが、車両の振動に対し、この保持機能
が充分でなく、次第にゆるんでし１うことか最近問題と
なってきている。However, although the differential gear mechanism of this spare tire hoisting device has the function of holding the spare tire in the hoisted state, this holding function is not sufficient against vibrations of the vehicle, and the spare tire gradually loosens. This has recently become a problem.
そこで、スペアタイ−ヤ巻き上げ装置の逆転防止装置に
関しての考案が種々なされているが、これらは次のよう
な欠点がある。Therefore, various designs have been made regarding reverse rotation prevention devices for spare tire hoisting devices, but these devices have the following drawbacks.
（１）駆動軸の左端にハンドルを挿入すると逆転防止の
係合が外れて、巻き上げ装置の逆転が可能となる型式（
特公昭５１−４６９３５号、実開昭５３−４４８４３号
）のものはハンドルの係止孔に泥や小石が進入すると機
構が作動しなくなったり、あるいは錆付いたりして信頼
性に問題がある。(1) When the handle is inserted into the left end of the drive shaft, the anti-reverse engagement is released and the hoisting device can be reversed (
The mechanism disclosed in Japanese Patent Publication No. 51-46935 and Japanese Utility Model Publication No. 53-44843) has reliability problems because if mud or pebbles enter the locking hole of the handle, the mechanism may stop working or become rusted.
（２）板ばねを用いた型式（実開昭５３−４４８４４号
、実開昭４８−２５４４２号）のものは構造が簡単で安
価であるが、例えば駆動軸を５ｋｇ・ｍで締め付けた場
合、差動歯車の減速比を１０分の１とすると約１ｋｇ・
ｍ程度の逆転時ｔＬのトルクが必要となり、この値を満
たすためには相当大型の板ばねを必要とするとともに、
耐久性にも問題がある。(2) Types using leaf springs (Utility Model Application No. 53-44844, Utility Model Application No. 48-25442) have a simple structure and are inexpensive, but for example, when the drive shaft is tightened to 5 kg・m, If the reduction ratio of the differential gear is 1/10, it will weigh approximately 1 kg.
A torque of tL is required at the time of reverse rotation of about m, and in order to satisfy this value, a fairly large leaf spring is required, and
There is also a problem with durability.
