BRIEF SUMMARY
TECHNICAL FIELD
This invention relates to an auxiliary apparatus for a vehicle.
BACKGROUND ART
Power equipment such as an engine is mounted on a vehicle. Also mounted are auxiliary apparatus such as a water pump, an idler, a power steering hydraulic pump, an alternator, and an air conditioner compressor, which serve functions auxiliary to that of the power equipment. These auxiliary apparatus are driven by the power equipment in a way in which pulleys or electromagnetic clutches of the auxiliary apparatus are connected to the power equipment via a crankshaft pulley and a belt.
By the way, these auxiliary apparatus are installed in a limited boarding space in the periphery of the power equipment in a limited-space power equipment room by being fixed to the power equipment.
In view of the need to be installed in a limited boarding space and the need to be produced at lower production costs by omitting each own pulley and decreasing the number of component parts, a pair of auxiliary apparatus have been conventionally known in which a water pump and a power steering hydraulic pump are combined in a tandem form. In this type of vehicular auxiliary apparatus comprising a pair of auxiliary apparatus, one housing and one driving shaft are commonly used by these two apparatus and a single pulley is secured on this driving shaft. Therefore, by making that pulley connected to power equipment through a crankshaft pulley and a belt, the two apparatus are respectively driven by the power equipment.
In the aforementioned conventional vehicular auxiliary apparatus, however, it is true that the common use of the driving shaft allows these two apparatus to transmit power to each other, but one of the auxiliary apparatus and the other of the auxiliary apparatus cannot be handled independently of each other because the two apparatus cannot be detached from or attached to each other due to the common use of the housing and the driving shaft.
That is to say, these vehicular auxiliary apparatus cannot deal with a situation in which one of the auxiliary apparatus is always needed and the other of the auxiliary apparatus is optionally needed. In addition, in these vehicular auxiliary apparatus, if one of the auxiliary apparatus should become out of order and needs to be mended or replaced with a new one, the other of the auxiliary apparatus must also be dismantled simultaneously, and therefore the mending or replacing operation is troublesome.
This invention has been made in view of the above conventional circumstances. It is an object to be attained to allow one of the auxiliary apparatus and the other of the auxiliary apparatus to be handled independently of each other, while satisfying the need to be installed in a limited boarding space and the need to be produced at lower production costs.
SUMMARY OF THE INVENTION
A vehicular auxiliary apparatus comprises a pair of auxiliary apparatus which are mounted on a vehicle, being combined in a tandem form, and serve functions auxiliary to that of power equipment of the vehicle, and is characterized in that one of the auxiliary apparatus and the other of the auxiliary apparatus can transmit power to each other and are attachable to and detachable from each other.
Since one of the auxiliary apparatus and the other of the auxiliary apparatus can transmit power to each other, each own pulley can be omitted and the number of component parts can be decreased, and therefore this vehicular auxiliary apparatus can be produced at low costs.
Moreover, because one of the auxiliary apparatus and the other of the auxiliary apparatus are attachable to and detachable from each other, these can be handled independently of each other.
That is to say, by detaching one of the auxiliary apparatus from the other of the auxiliary apparatus, the vehicular auxiliary apparatus can deal with a situation in which the one of the auxiliary apparatus is always needed and the other of the auxiliary apparatus is optionally needed. Besides, if one of the auxiliary apparatus should become out of order and has t
