Abstract
The utility model relates to a single cylinder motor vehicle, in particular to a hydraulic power-assisted steering system, which is characterized in that a single cylinder engine is connected with a steering oil pump through a drive mechanism, the oil outlet of the steering oil pump is connected with an oil inlet of a hydraulic power-assisted steering gear through a high-pressure oil pipe, the oil outlet of the hydraulic power-assisted steering gear is connected with an oil inlet of an oil can through an oil return pipe, the oil outlet of the oil can is connected with the oil inlet of the steering oil pump through an oil inlet pipe, and the steering rocker of the hydraulic power-assisted steering gear is connected with steering wheels through steering longitudinal draw bars. The technical scheme can facilitate drivers to easily and flexibly control the steering of motor vehicles by using the smaller control force, which solves the weaknesses of arduous steering and inflexibility of single cylinder motor vehicles, especially when carts are in overloading.
Description
Technical field:
The utility model relates to a kind of single cylinder engine motor-car, relate in particular to a kind of hydraulic power-assist steering system.
Background technology:
At present domestic have only twin-tub, multi-cylinder car to adopt the hydraulic directio power-assisted, and power actuated vehicles such as single cylinder low speed load-carrying vehicle, single cylinder trac., single cylinder three wheeled motor vehicle, single cylinder motor bike all do not adopt hydraulic power-assisted steering, but adopting the steering swivel system of pure machinery, this steering swivel system exists and turns to shortcomings such as heavy, inflexible.
Summary of the invention:
The purpose of this utility model is exactly at the existing in prior technology deficiency, and a kind of technical scheme of single-cylinder hydraulic servo steering system is provided, and this scheme is improved the steering swivel system of single cylinder vehicle, makes to turn to the light, flexible of change.
This programme is realized by following technical measures: it comprises oil can, steering side tube, wheel flutter, hydraulic power steering gear and connected bearing circle, single cylinder engine is connected with power steerig pump by transmission device, the oil outlet of this power steerig pump is connected with the oil inlet of hydraulic power steering gear by high pressure fuel pipe, the oil outlet of this hydraulic power steering gear is connected with the oil inlet of described oil can by oil return pipe, the oil outlet of this oil can is connected with the oil inlet of described power steerig pump by oil inlet, and the pitman arm of described hydraulic power steering gear is connected with wheel flutter by steering side tube.
Total system is power with the single cylinder engine, drive power steerig pump work by transmission device, enter hydraulic power steering gear by various pipeline high pressure oils, the chaufeur steering wheel rotation drives the pitman arm swing, the hydraulic power steering gear high pressure oil applies a propelling thrust in the same way to pitman arm simultaneously, further drive wheel flutter work, realize the direction power-assisted by steering side tube.When bearing circle did not rotate, the hydraulic power steering gear high pressure oil did not apply propelling thrust to pitman arm, did not produce the power-assisted effect.
Described transmission device is V-belt or gear or other transmission device.
The beneficial effect of this programme can be learnt according to the narration to such scheme, use this scheme can make steerman with less control effort, control vehicle that can easy and flexible turns to, and has solved the single cylinder engine motor vehicle and has particularly turned to heavy, inflexible shortcoming during the cart heavy duty.
Description of drawings:
Fig. 1 is the structural representation of the utility model specific embodiment.
Among the figure, 1 is single cylinder engine, and 2 is the V-belt, and 3 is power steerig pump, and 4 is oil inlet, and 5 is oil can, and 6 is high pressure fuel pipe, and 7 is oil return pipe, and 8 is hydraulic power steering gear, and 9 is bearing circle, and 10 is pitman arm, and 11 is steering side tube, and 12 is wheel flutter.
The specific embodiment:
For clearly demonstrating the technical characterstic of this programme,, and, this programme is set forth in conjunction with its accompanying drawing below by a specific embodiment.
By accompanying drawing 1 as can be seen, the single-cylinder hydraulic servo steering system of this programme, oil can 5, hydraulic power steering gear 8, bearing circle 9, steering side tube 11, wheel flutter 12 and various oil pipe are arranged, also have single cylinder engine 1, transmission device, the power steerig pump 3 that power is provided for total system.Single cylinder engine 1 drives power steerig pump 3 work by transmission device, oil can 5 is connected with power steerig pump 3 by oil inlet 4, power steerig pump 3 is connected with hydraulic power steering gear 8 by high pressure fuel pipe 6, and the pitman arm 10 of hydraulic power steering gear 8 drives wheel flutter 12 work by steering side tube 11.Transmission device can be V-belt or gear or other transmission device, and present embodiment is V-belt 2.
Total system is a power with single cylinder engine 1, drive power steerig pump 3 work by transmission device, enter hydraulic power steering gear 8 by various pipeline high pressure oils, chaufeur steering wheel rotation 9 drives pitman arm 10 swings, hydraulic power steering gear 8 high pressure oils apply a propelling thrust in the same way to pitman arm 10 simultaneously, further drive wheel flutter 12 work, realize the direction power-assisted by steering side tube 11.When bearing circle 9 did not rotate, hydraulic power steering gear 8 high pressure oils did not apply propelling thrust to pitman arm 10, do not produce the power-assisted effect.
