Abstract

A kind ofly be used to advance the propulsion unit 10 of linotype machine to be provided with petrol engine 12, this petrol engine 12 can have pulling/backflush device or motor-driven starter.Motor 12 is connected to oil hydraulic pump 16 via the centrifugal clutch 14 of a known type, and this oil hydraulic pump 16 comprises hydrostatic driver element 18.In a preferred embodiment, clutch 14 is designed to engage between priming speed and idling.

Description

The effort reducing start mechanism that is used for hydraulically propelled vehicles
Technical field
The serial number that the application requires on December 19th, 2007 to propose is the rights and interests of 61/015,057 U. S. application, and its content is by with reference to being merged in.
Background technique
The linotype machine propulsion unit is known, the linotype machine propulsion unit that assignee for example of the present invention sells with the LineDriver trade mark.In these unit, petrol engine directly drives oil hydraulic pump, and this drives oil hydraulic pump accommodating fluid static(al) drive system.The unit of even now gets fine for the purposes work of its expection, but when be used for lower temperature, pilots engine because hydraulic fluid high viscosity at a lower temperature makes it be difficult to (pulling or electronic), so motor is difficult to start.
Summary of the invention
A kind of centrifugal clutch of known type places between motor and the oil hydraulic pump.In wide meaning of the present invention, clutch designs is for only engaging on engine idle.In a preferred embodiment, clutch designs is for engaging between starting (recoil or electronic) speed and idling.In the preferred embodiment, in case engine start, clutch will be engaged, and make will not have joint or separation at normal operation period.
Can show these and other purpose and advantage of the present invention in conjunction with the accompanying drawings more all sidedly from following description, wherein run through the identical reference character of several views and indicate same or analogous part.
Description of drawings
Fig. 1 illustrates the combination of motor-clutch of the present invention-pump.
Fig. 2 illustrates the illustrative arrangement figure of propulsion unit.
Embodiment
Propulsion unit, for example will be used to advance the propulsion unit of linotype machine to be designated as 10 usually, and be provided with petrol engine 12, this petrol engine 12 can have pulling/backflush device or motor-driven starter.Motor 12 is connected to oil hydraulic pump 16 via the centrifugal clutch 14 of a known type, and this oil hydraulic pump 16 comprises hydrostatic driver element 18, and this hydraulic drive unit 18 is connected to wheel motor 20 again.In a preferred embodiment, clutch 14 is designed to engage between starting (recoil or electronic) speed and idling.As an example, priming speed can be 600rpm, and engaging speed can be 830rpm and idling can be 1440rpm.In the preferred embodiment, in case engine start, clutch will be engaged, and make will not have joint or separation at normal operation period.
Can be contemplated that and to carry out various changes and improvements to propulsion unit, and not depart from as the spirit and scope of the present invention defined by the following claims.

Claims (3)

1. in a kind of propulsion unit, this propulsion unit has gas engine, by described gas-engine-driven oil hydraulic pump and hydrostatic driver, improvement comprises: centrifugal clutch, this centrifugal clutch be by described engine-driving, and drive described oil hydraulic pump.
2. propulsion unit as claimed in claim 1, wherein said motor has idling, and centrifugal clutch engages on described idling.
3. propulsion unit as claimed in claim 1, wherein said motor has idling and priming speed, and centrifugal clutch engages between described idling and described priming speed.
